Overview

Format for 2006 Return

To streamline the collection of corporate information, corporations are able to file a combined CT23 Corporations Tax and Annual Return for the 2000 and subsequent taxation years. The CT23 Corporations Tax Return collects the information required by the Corporations Tax Act. The Annual Return collects the information required by the Ministry of Government Services (MGS) under the authority of the Corporations Information Act. For information on the Annual Return, please refer to page 27 of this guide.

Also, more corporations will have the option of filing a CT23 Short-Form Corporations Tax and Annual Return. Please refer to page 7 of this guide for further information on who may file a CT23 Short-Form Corporations Tax and Annual Return.

This guide is to be used to complete the 2006 CT23 Corporations Tax and Annual Return.

Acronyms used in this guide are as follows:

  • CT23 - refers to the CT23 Corporations Tax Return.
  • Annual Return - refers to the MGS Annual Return.
  • CT23 and Annual Return - refers to the combined CT23 Corporations Tax and Annual Return.
  • References to the Corporations Tax Act are noted as - s.5 (meaning refer to section 5).
  • References to the Ontario Ministry of Finance Information Bulletins or Interpretation Bulletins are noted - Information Bulletin 4003R1 or Interpretation Bulletin 3004.

    Copies of these Bulletins may be obtained by calling the Revenue Operations and Client Services Branch at the numbers shown on page 2 or by visiting our website at: ontario.ca/finance
  • References to the federal Income Tax Act, Canada are noted as " fed".

CT23 and Annual Return Format

The CT23 Corporations Tax and Annual Return consists of 20 pages, including 3 pages relating solely to the MGS Annual Return (MGS Schedules A and K).

The Corporations Tax Act

This guide is provided for convenience only. For legislative accuracy refer to the Corporations Tax Act, R.S.O. 1990, Chapter 40, as amended ("Act"). Failure to comply with the provisions of the Act may result in loss of your Ontario Charter and dissolution and forfeiture of the corporation' s property to the Crown.

Highlights of Amendments

Capital tax deduction and rates

The capital tax deduction will increase and the capital tax rate will decrease (as shown in the table below) until capital tax is fully eliminated on January 1, 2012.

  Jan 1, 2005 Jan 1, 2006 Jan 1, 2007 Jan 1, 2008 Jan 1, 2009 Jan 1, 2010 Jan 1, 2011 Jan 1, 2012
Deduction ($ Millions) 7.5 10 12.5 15 15 15 15 Eliminated
Rate (%) 0.3 0.3 0.3 0.3 0.225 0.15 0.075

The 2006 Ontario Budget proposed to cut the current capital tax rates by five per cent, effective January 1, 2007 - two years earlier than the first currently scheduled rate cut.

At the time of printing the 2006 Ontario Budget proposed measures required passage by the legislature and royal assent to become law.

Treatment of Corporations Incorporated Outside Canada

For taxation years ending after May 11, 2005, Ontario corporate tax liability is determined with reference to whether a corporation is resident (rather than incorporated) inside or outside Canada.

Instalments

For taxation years commencing after December 31, 2005, Ontario parallels the calculation of instalments under the federal Income Tax Act (ITA) where a corporation has been involved in a wind-up or rollover, or where the preceding taxation year is less than 183 days. For additional information, refer to Info.B. 4007R1.

Four new tick boxes on page 3 of CT23

The 2006 CT23 Tax Return includes four new tick boxes on page 3. These boxes must be checked if any of the following is applicable:

  • first year filing after incorporation or amalgamation;
  • first year filing of a parent after winding-up a subsidiary;
  • the corporation was involved in a non-arm's length transaction under subsection 85(1) or 85(2) of the ITA;
  • Section 83.1 of the CTA applies (redirection of payments for certain electricity corporations).

New Ontario CT Schedule 24

This schedule is filed by corporations for the first year of filing after incorporation, amalgamation or by parent corporations filing for the first time after winding-up a subsidiary corporation(s) under section 88 of the ITA during the current taxation year. For additional information, refer to the Identification Section, page 12 of this guide.

New Ontario CT Schedule 44

This schedule is filed by corporations which received all or substantially all (90 per cent or more) of the assets of a non-arm's length corporation in the taxation year, and subsection 85(1) or (2) of the ITA applied. For additional information, refer to the Identification Section, page 12 of this guide.

Authorizing or Cancelling a Representative

This new form is to be completed to authorize the release of confidential information about your Corporations Tax Account or Mining Tax Account to the representative named, or to cancel consent for an existing representative.

DFILE

Effective March 1, 2006, a return on CD-ROM will be accepted.

Ontario Charitable Donations and Gifts

Schedule 2 has been revised to account for Ontario paralleling the new federal rule for charitable donations carried forward after an acquisition of control.

Ontario Political Contributions

The maximum deduction allowed for political contributions in computing a corporation's taxable income for a taxation year has been increased from $15,000 to $16,800 for contributions made after December 31, 2003 and before January 31, 2009. For additional information, refer to Interpretation Bulletin 3002R2.

Specified Tax Credits

Ontario Film and Television Tax Credit (OFTTC)

The OFTTC is increased from 20% to 30% for labour expenditures incurred after December 31, 2004 and increased from 30% to 40% for the first $240,000 of labour expenditures on a first-time production.

Ontario Production Services Tax Credit (OPSTC)

The OPSTC is increased from 11% to 18% for labour expenditures incurred after December 31, 2004 and before April 1, 2006.

As announced on February 9, 2006, the Ontario government proposes to extend the 18 per cent tax credit rate for the OPSTC until March 31, 2007.

Ontario Computer Animation and Special Effects Tax Credit (OCASE)

The OCASE's previous cap of 48% of production costs has been removed for labour expenditures incurred after May 11, 2005.

Ontario Book Publishing Tax Credit (OBPTC)

Effective for books published after May 11, 2005, the OBPTC is available for more categories of books by replacing the single category for children's books with four categories as follows: children's fiction, children's nonfiction, children's poetry and children's biography.

Ontario Interactive Digital Media Tax Credit (OIDMTC)

Effective for eligible products completed after May 11, 2005, qualifying corporations no longer need to own at least 90 per cent of the copyright.

The 2006 Ontario Budget proposes to raise the tax credit from 20 per cent to 30 per cent for corporations qualifying under the existing OIDMTC provisions.

The Budget also proposes to extend the eligibility for the OIDMTC at a rate of 20 per cent to multi media developers that exceed the current size test and to fee for- service work done in Ontario. For further information, please refer to Information Notice 6013.

Ontario Sound Recording Tax Credit (OSRTC)

The following changes are effective for taxation years ending after May 11, 2005 or for master recordings completed after May 11, 2005:

  • The minimum period of time required by an eligible company to carry on a sound recording business is reduced from 24 to 12 months.
  • The minimum required playing time for an eligible sound recording is reduced from 40 to 15 minutes.
  • A sound recording company is required to market an eligible recording through a 'distribution plan approved by a person designated by the Minister of Culture' instead of an 'established national distributor.'
  • The definition of sound recording has been expanded to include a recording made on any fixed medium (e.g., MP3 files).

Federal Concordance Measure

The 2006 Ontario Budget proposes to parallel, subject to federal implementation, the income tax measures noted below as announced by the federal government in either November 2005 or in the 2005 Federal Budget, as they apply to corporations and their effective dates. They are as follows:

  • extension of the carry-forward period for non-capital losses from 10 to 20 years;
  • capital cost allowance provisions relating to cogeneration systems that use black liquor;
  • tax deferral for a patronage dividend paid by an agricultural cooperative corporation that is received in the form of eligible shares, where the income inclusion would be deferred from the year the share is received to the year the share is disposed of;
  • limit to the expenses that a taxpayer can claim in respect of certain transactions, such as the issuance of shares, where the amount of the expenditure on which a tax credit or deduction may be claimed is limited to the cash outlay

Do you have to file an Ontario Corporations Tax Return?

Exempt from Filing (EFF)

You may be exempt from filing a CT23 for the current taxation year, if your corporation meets all of the criteria listed below:

  • files a federal income tax return (T2) with Canada Revenue Agency (formerly Canada Revenue Agency);
  • has no Ontario taxable income;
  • has no Ontario Corporations Tax payable;
  • is a Canadian-controlled private corporation (CCPC) throughout the taxation year (i.e., generally, a private corporation with 50% or more shares owned by Canadian residents as defined in subsection 125(7) of the Income Tax Act, [Canada]);
  • has provided its Canada Revenue Agency Business Number to the Ontario Ministry of Finance, Corporations Tax;
  • is not subject to the Corporate Minimum Tax (i.e., alone or as part of an associated group whose assets exceed $5 million or whose total revenues exceed $10 million).

Corporations are required to file an EFF Corporations Tax Return declaration form on page 2 for every taxation year for which the status is claimed (effective for taxation years ending on or after January 1, 2000).

Corporations who are claiming EFF status may still be required by the Ministry of Government Services to file an Annual Return; please refer to page 27 of this guide.

Financial Institutions (banks, credit unions, mortgage investment corporations, registered securities dealers, bank mortgage subsidiaries, loan and trust corporations and trustees to the public) and insurance corporations, do not qualify for the exemption from filing a CT23 for a taxation year.

The following loss situations will require otherwise EFF corporations to file a CT23 tax return complete with all related schedules and financial statements:

  • If a corporation has a loss in the current taxation year that is to be carried back and applied to a previous taxation year(s), regardless of whether the loss is the same as for federal purposes or not, a CT23 tax return is required for the current taxation year. The corporation must also provide information indicating that the loss is to be carried back and specify the year and the amount of loss to be carried back to each taxation year.
  • If a corporation has a prior year loss, that is not the same for both federal and Ontario purposes and the corporation is applying a loss carry forward from the prior year to the current year, a CT23 tax return for the prior taxation year in which the loss was incurred is also required. Although a tax return for the loss year is not required where the loss is not being applied, the Ministry will accept the filing of a tax return for a loss year at the time the loss is incurred.
  • If a corporation has a prior year loss that is the same for both federal and Ontario purposes, but in the current taxation year the corporation is applying a different amount of loss for Ontario than the loss amount being applied for federal income tax purposes, the corporation is required to file a CT23 tax return for the current taxation year only.
  • A CT23 for an EFF period may be required, if requested by the ministry.

Ontario Corporations Tax Account No. (MOF)

In order to file a CT23 or an EFF declaration you will require an Ontario Corporations Tax Account No. (MOF). This account number will be assigned to you shortly after you register with the Ministry of Ministry of Government Services (MGS). If you have already registered with MGS and are still unaware of your Ontario Corporations Tax Account No. (MOF), please contact the ministry (see page 2 listing).

Can You File a CT23 Short-Form Corporations Tax and Annual Return?

A corporation may file a CT23 Short-Form Corporations Tax and Annual Return if it meets all of the following criteria:

  • The corporation is a Canadian-controlled private corporation (CCPC) throughout the taxation year.
  • The corporation has a permanent establishment only in Ontario (i.e., the corporation's Ontario allocation factor is 100%).
  • The corporation is not a financial institution.
  • The corporation's taxation year ends on or after January 1, 2001, its gross revenue and total assets are each $1,500,000 or less; OR the corporation's taxation year commences after September 30, 2001, its gross revenue and total assets are each $3,000,000 or less.
  • The corporation's total assets and gross revenues are each $1,000,000 or less.
  • The corporation's taxable income for the taxation year is $200,000 or less. For a taxation year with less than 51 weeks, taxable income must be grossed-up. The gross-up equals the corporation's taxable income multiplied by 365 days and divided by the number of days in its taxation year.
  • The corporation is not a member of a partnership/joint venture or a member of an associated group of corporations during the taxation year.
  • The only tax credits the corporation is claiming are the Incentive Deduction for Small Business Corporations (IDSBC), the Co-operative Education Tax Credit (CETC), the Graduate Transitions Tax Credit (GTTC), or the Apprenticeship Training Tax Credit (ATTC).
  • A Family Farm or Fishing Corporation which is not subject to the Corporate Minimum Tax (CMT) may also use the CT23 Short-Form Corporations Tax and Annual Return for a taxation year ending on or after January 1, 2000, if it meets all of the above criteria excluding the total asset and gross revenue test.

When must you file?

A completed CT23, Annual Return (if applicable) and supporting documents must be received within 6 months after the end of the corporation's taxation year. The Minister considers the CT23 delivered on the date it is received by the Ministry of Finance.

What are the penalties if you file your CT23 late and have not made sufficient payments for the year?

Rules for Calculating Penalty

The following penalties may be imposed for filing incomplete or late CT23s that are required to be filed on or after December 18, 1998. A taxpayer having one late filed CT23 may be subject to a penalty of 5% of the deficiency in the tax account for the taxation year, plus an additional 1% for each full month that the CT23 is late, to a maximum of 12 months. A taxpayer having two late filed CT23s within 4 taxation years may be subject to a penalty on the latter return of 10% plus 2% for each full month that the CT23 is late to a maximum of 20 months. For additional details on these penalties, refer to Information Bulletin 4004R, Penalties and Fines.

When will we pay or charge interest?

Calculating Daily Compound Interest (Information Bulletin 4010)

Notice of (Re)Assessment

  • Debit Interest at the rate provided in the Regulations, is calculated and charged daily for every day that there is a deficiency in your account (includes unpaid taxes, interest, penalties and other unpaid amounts). A corporation's account is divided for interest purposes, by period of time, into an instalment account for the instalment period and a tax account for the period after the instalment period. The instalment period is the period from the first day of your taxation year to the day before the balance of tax due date or the day before the most recent (re)assessment for the taxation year, whichever is earlier.
  • Instalment credit interest, at the rate provided in the Regulations, is calculated daily for each day that there is a surplus in your instalment account, from the last day of the first month in the instalment period to the end of the instalment period.
  • Credit interest on overpayments at the rate provided in the Regulations, is calculated and allowed daily for each day there is a surplus in your tax account after the end of your instalment period for the taxation year. If a return is not filed on time, no credit interest will be allowed for the period from the day your return was required to be filed to the day after your return is filed.

Application of Payments

Any amount paid, applied or credited (on or after August 1, 1995) in respect of amounts payable, will be applied firstly against any tax owing, secondly against any penalty owing, third against any interest owing and fourth against any other amounts owing by the corporation.

Revised Instalments

Instalment debit and credit interest will be re-calculated to reflect revised instalments resulting from the reassessment of the tax payable on which the instalments are based, except in the case of loss carry-backs.

Effects of Loss Carry-backs

Loss carry-backs for losses incurred in taxation years that end on or after August 1, 1995, do not affect the calculation of interest for the instalment account, the tax account or for the purposes of determining the amount of the late-filing penalty (if the CT23 due date is on or after August 1, 1995), until the date that is the later of the following:

  1. The first day of the taxation year after the loss year;
  2. The day on which the corporation's CT23 for the loss year is delivered to the Minister; or
  3. The day on which the Minister receives a request in writing from the corporation to reassess the particular taxation year to take into account the deduction of the loss.

Interest off-set

Debit and credit interest is netted for a particular taxation year. Netting between different taxation periods is not permitted.

What should you include with your CT23?

Paper returns and D-Filed returns

The ministry prefers corporations to file the financial statements prepared for the shareholders of a corporation (Refer to Information Bulletin 4002R1). However, the ministry will normally accept a hard copy of the General Index of Financial Information (GIFI).

Where the GIFI is filed, the ministry may request financial statements in the form specified by the legislation (see paragraphs 2 and 3 of Information Bulletin 4002R1) where the GIFI is incomplete, inaccurate, or does not provide sufficient information to verify the corporation's tax liability under the Act.

Whatever method is used for filing, financial statements of all partnerships and/or joint ventures of the corporation must be filed with the ministry.

Elections for Rollovers

The transferor and transferee corporations in a "rollover" are required to file a joint Ontario election made under sections 29.1 and 31.1 of the Act. These elections are the Ontario counterparts to federal elections made under subsections 85(1), 85(2) and 97(2) of the Income Tax Act (Canada). Corporations should use a hard copy of federal form T2057, T2058 or T2059 as appropriate, altered as necessary for Ontario purposes.

Corporations are recommended to file their Ontario election form with their CT23. However, under the Act, corporations are allowed to file their Ontario election by the latest date that a federal tax return must be filed by any party to the election. This date may be subsequent to the due date for the CT23.

Transferor and transferee corporations must file a copy of their federal election form T2057, T2058 or T2059 with their CT23, where the transferee and the transferor are either a corporation or a partnership with at least one corporate partner.

Corporations that elect under section 85 of the federal Income Tax Act to transfer assets to or from a non-arm's length corporation with a permanent establishment in a Canadian jurisdiction other than Ontario must file additional information. See Tax Legislation Bulletin 96-3 'Inter-Provincial Asset Transfers' for details. The bulletin is available by calling the ministry at the numbers listed on page 2 of this guide, or refer to our website at ontario.ca/finance.

Send your tax payment(s) (payable to the Minister of Finance) and completed CT23 by the appropriate due dates to:

Ministry of Finance
PO Box 620, 33 King Street West
Oshawa ON  L1H 8E9

For information on what should be included with your Annual Return please see page 27 of this guide.

After You File

What happens to your CT23 after we receive it?

When we receive your CT23, we review it based on the information you provided and send you a Notice of Assessment based on that review.

In some cases your CT23 may be selected for a more detailed review and additional information may be requested

Tax Payments

Corporations may make tax payments using any of the following methods:

  • at any financial institution in Ontario where the corporation maintains an account;
  • by mail or delivery to any Ministry of Finance tax office;
  • electronically, using a financial institution's Internet Banking Service. Internet Banking, where offered, is an online tax payment service available 24 hours a day, seven days a week, whereby a corporation can remit tax payments through its financial institution's website.

Is the monthly payment of instalments always required?

No. Monthly instalments are not required under the following circumstances:

  • First Year Filing - all taxes must be paid on or before the balance of tax due date which is either 2 or 3 months after the end of the taxation year. (Refer to Balance of Tax below.)
  • Tax payable for either the current or previous taxation year is less than $2,000 - all taxes must be paid on or before the balance of tax due date which is either 2 or 3 months after the end of the taxation year. (Refer to Balance of Tax below)

Quarterly instalments

Tax must be paid by quarterly instalments (every three months), if your tax payable for the current year or preceding year is equal to or greater than $2,000 and less than $10,000. This applies to taxation years commencing in 2002.

Quarterly instalments should be calculated according to one of the following methods:

  • ¼ of the tax payable for the current taxation year
  • ¼ of the tax payable in the previous taxation year
  • for the first quarter of the taxation year, ¼ of the tax payable two years ago; and for the next three quarters, 1/3 of the difference between last year's tax payable and the instalment paid for the first quarter.

Monthly instalments

Tax must be paid by monthly instalments, if your tax payable for the current taxation year and for the previous taxation year are each $10,000 or more.

Each instalment, usually due on the last day of the month, should be calculated according to one of the following methods:

  • 1/12 of the tax payable for the current taxation year;
  • 1/12 of the tax payable in the previous taxation year;
  • for the first two months, 1/12th of the tax payable two years ago; and for the next ten months, 1/10th of the difference between last year's tax payable and the amount paid for the first two months.

When calculating instalments, if one of the previous two taxation years used to calculate the instalment was less than 365 days, the tax payable for the year must be grossed up to a full 365 days. For taxation years beginning after December 31, 2005, if one of the previous taxation years was less than 183 days, the tax for that year is substituted by the greater of:

  • the tax payable grossed up to 365 days; and
  • the tax payable for the last preceding year that did exceed 182 days.

A corporation that is the successor corporation of amalgamated corporations must use the total predecessor corporations' tax liabilities in the computation of instalments.

For taxation years beginning after December 31, 2005, when a corporation is involved in a wind-up or rollover, it must include the subsidiaries' tax liabilities or the transferor corporations' tax liabilities, in the calculation of instalments.

Balance of Tax

The difference between the current year tax liability and the amounts paid by instalments represents the balance of tax due.

The balance of tax due must be paid within three months after the end of your taxation year, if your corporation was a Canadian-controlled private corporation throughout the taxation year and had taxable income of purposes (for additional information regarding the business limit for Ontario purposes refer to page 13) for the previous taxation year.

In all other cases, the balance of tax is due within two months after the end of your taxation year.

If the previous taxation year was less than 51 weeks, the corporation's business limit for Ontario purposes must be prorated (i.e., $400,000 × the number of days in taxation year ÷ 365). The taxable income must not be more than this prorated limit.

For Accounts or Payment enquiries, please call the Corporations Tax Branch Accounts Enquiry lines at the numbers listed on page 2.

Voluntary Disclosure

It is the policy of the Ontario Ministry of Finance that any corporation or individual, who voluntarily discloses a violation of a statute administered by the ministry, be allowed to settle any related debt by making full payment including interest.

If the above condition is met, and subject to the comments in the paragraph below, the ministry will not prosecute or impose civil penalties for gross negligence, willful evasion, or late-filing.

Claim forms can be obtained by calling the ministry's Information Centre, the telephone numbers on page 2 of this guide or by downloading the form from our website: ontario.ca/finance.

The OITC is a 10% refundable tax credit for qualifying public and private corporations (prior to May 5, 1999 only qualifying Canadian-controlled private corporations [CCPCs] were eligible) having a permanent establishment in Ontario.

The OITC is calculated on qualifying expenditures (annual maximum of $2,000,000) made in the taxation year for Scientific Research and Experimental Development (SR&ED) carried on in Ontario that are eligible for the federal investment tax credit under fed.s.127.

Corporations are eligible to claim the full OITC where their Ontario taxable paid-up capital and federal taxable income in the preceding taxation year do not exceed $25 million and $200,000 ($300,000 if the taxation year ends after 2002) respectively. The annual qualifying expenditure limit of $2 million is progressively reduced for those corporations:

  • whose 'taxable paid-up capital' or 'adjusted taxable paid-up capital' in the preceding taxation year, is greater than $25 million but less than $50 million; and
  • whose federal taxable income is:
    • more than $200,000 but less than $400,000 in the preceding taxation year that ends before 2003; or
    • more than $300,000 but less than $500,000 in the preceding taxation year that ends after 2002 (following legislative changes introduced in the 2003 federal budget).

If the corporation is part of an associated group, the Ontario taxable paid-up capital and federal taxable income of these corporations must also be included in the determination of the annual qualifying expenditure limit.

Effective for taxation years that end after March 22, 2004, small CCPCs that have a group of common investors (that was not formed to gain access to multiple expenditure limits) will not have to share the $2 million expenditure limit.

Effective December 9, 2002, associated non-resident corporations with no permanent establishment in Canada are to be included as part of an associated group.

Credit unions and insurance corporations are required to use taxable paid-up capital employed in Canada as determined for the federal large corporations tax instead of 'taxable paid-up capital' or 'adjusted taxable paid-up capital'.

Co-operative Education Tax Credit (CETC)

If claiming the CETC, attach CT23 Schedule 113 and enter the total tax credit claimed on page 7, line [192].

The CETC is a refundable tax credit available to taxpayers hiring eligible university or college students enrolled in a recognized post-secondary education program. Ontario corporations with a permanent establishment in Ontario subject to Ontario corporate income tax are eligible for the credit.

There are two types of work placements: co-operative work placements which commence after July 31, 1996 and leading edge technology (LET) work placements which commence after December 31, 1997.

A credit of 10% is available to corporations whose previous taxation year's salaries and wages paid are equal to $600,000 or more. An enhanced credit of 15% is available to businesses whose previous taxation year's payroll was $400,000 or less. The enhanced credit is phased out for payroll between $400,000 and $600,000. The enhanced credit applies to work placements commencing after December 31, 1997.

The maximum credit is $1,000 for each work placement, regardless of the rate claimed in calculating the credit.

A qualifying co-operative work placement must be a minimum of 10 weeks while a qualifying leading edge technology work placement must be a minimum of 10 weeks with an average of 24 hours of employment per week.

For most work placements, the maximum employment period is four months. However, if the employment period of a qualifying work placement exceeds four months, there could be more than one qualifying work placement for that particular student. Each four month employment period is considered a separate qualifying work placement each of which qualifies for a maximum of $1,000.

The maximum eligible employment period for a LET program is 16 months except where the employment commences after May 4, 1999 under a qualifying apprenticeship program, in which case the maximum eligible employment period is extended to 24 months.

The 2004 Ontario Budget amended the CETC following the implementation of the new Apprenticeship Training Tax Credit (ATTC). The CETC continues to be available for qualifying co-op placements. However, with respect to qualifying leading edge technology work placements, transitional rules apply for apprenticeships in their first 36 months that straddle May 18, 2004. Salaries and wages paid before May 19, 2004 qualify for the CETC, and amounts paid or payable for services performed after May 18, 2004 qualify for the ATTC.

For apprenticeships not in their first 36 months and for work placements in approved fields of study other than co-operative education programs, no deduction may be claimed for salaries and wages paid after December 31, 2004 and for employment commencing after October 25, 2004.

Eligibility for the CETC requires:

  • a letter of certification from the Ontario college, university or other post-secondary institution, containing information as specified by the Minister, stating that the student is enrolled in a qualifying education program; or
  • a voucher for LET programs (other than an apprenticeship) stating that the educational program meets the definition of a qualifying program in leading-edge technology and that the work performed by that student during the work placement is in a related field.

For LET work placement commencing before March 1, 1999 refer to the important notice section of the Ontario Jobs Opportunity Voucher for special instructions.

Leading-edge technology programs include such fields as computer science, telecommunications technology, sciences (microbiology), mathematics and engineering.

For additional information on the CETC refer to Interpretation Bulletin 3021R, dated May 2006.

Any questions relating to a course that qualifies as a qualifying cooperative education program or qualifying LET program should be directed to the Specialty Assessment Unit (SAU).

For productions that commenced principal photography on or after March 28, 2003, equity investments from government agencies will no longer be treated as assistance. An enhanced credit rate of 40% on the first $240,000 of qualifying labour expenditures is available for first time producers. Productions that are shot in Ontario outside of the Greater Toronto Area receive a 10 per cent bonus on all Ontario labour expenditures incurred for productions after May 2, 2000.

If the qualifying employment commenced after May 6, 1997, but before January 1, 1998, the GTTC rate is 10%. If the qualifying employment commenced after December 31, 1997 and before July 5, 2004, the following rates apply:

  • For corporations whose salaries and wages in the previous taxation year were $400,000 or less, the GTTC rate is 15%.
  • The GTTC rate is progressively reduced for corporations whose salaries and wages paid in the previous taxation year were over $400,000, but less than $600,000.
  • For corporations whose salaries and wages in the previous taxation year were $600,000 or greater, the GTTC rate is 10%.

The maximum credit for each qualifying placement is $4,000, regardless of the rate claimed in calculating the credit.

Qualifying employment is considered to be working an average of more than 24 hours per week during the employment period.

The tax credit may only be claimed by the corporation based on qualified expenditures paid during the first twelve-month period of qualified employment. The credit must be claimed in the taxation year in which the last day of the 12-month period of employment falls. The minimum employment period to qualify for the GTTC is six consecutive months. Consecutive periods of employment by two or more associated corporations is considered to be one continuous period of employment.

Qualifying post-secondary graduates must have graduated from a prescribed program of study, as prescribed by the regulations, within the past three years and cannot be related to the qualifying employer.

Qualifying graduates must have been unemployed or have not been employed by any person for more than 15 hours per week for at least 16 of the last 32 weeks immediately preceding the first day of qualifying employment.

A person who is considered to be a full-time student by the educational institution, is deemed to be employed while enrolled in a prescribed program of study.

Qualifying expenditures are salaries and wages, including taxable benefits, paid or payable to the employee during the first twelve-month period of employment, less any related government assistance received, including assistance received by associated corporations in respect of the qualifying employment (including grants, subsidies and forgivable loans). The qualifying expenditures have to be incurred prior to January 1, 2005.

The Budget also proposes to extend the eligibility for the OIDMTC at a rate of 20 per cent to multi media developers that exceed the current size test and to feefor-service work done in Ontario. For further information on the 2006 Ontario Budget, please refer to Information Notice 6013

For additional information please call the Ontario Media Development Corporation at 416 314-6858.

Ontario Sound Recording Tax Credit (OSRTC)

If claiming the OSRTC, enter the total amount of the tax credit on page 7, line [201]. The corporation must complete and include with its CT23 the OSRTC claim form. Attach the original certificate or a certified copy of the certificate obtained from the Ontario Media Development Corporation to your CT23 tax return.

The OSRTC claim form can be obtained by calling the ministry at the telephone numbers on page 2 of this guide or by downloading the form from our website: ontario.ca/finance.

For additional information please contact the Ontario Media Development Corporation at 416 314-6858.

The OSRTC is calculated as 20 per cent of qualifying expenditures incurred after January 1, 1999 by an eligible sound recording company with respect to an eligible Canadian sound recording by an emerging Canadian artist or group.

For expenditures incurred after January 1, 1999, the credit is available to all Ontario-based, Canadian controlled sound recording companies. An eligible sound recording company must carry on its sound recording business for at least 12 months (24 months for taxation years ending prior to May 12, 2005) preceding the taxation year and allocate, in the current taxation year, more than 50% of its taxable income to Ontario. The 12-month test includes time spent as a sole proprietorship and, in the case of a corporate reorganization, time spent by a predecessor corporation.

An eligible sound recording must be produced by an eligible sound recording company.

Effective for taxation years ending after May 11, 2005 or for master recordings completed after May 11, 2005:

  • The minimum required playing time for an eligible sound recording is reduced from 40 to 15 minutes.
  • The requirement that a sound recording company market an eligible recording through an 'established national distributor' is replaced with a more flexible requirement that the company have a 'distribution plan approved by a person designated by the Minister of Culture.'
  • The definition of sound recording has been expanded to include a recording made on any other fixed medium (e.g., MP3 files.).

For additional information on the OSRTC, please refer to Tax Legislation Bulletin, Number 01-4 dated, March 2001.

Apprenticeship Training Tax Credit (ATTC)

If claiming the ATTC, attach CT23 schedule 114 and enter the total tax credit claimed on page 7 line [203] of the CT23. Enter the total number of apprentices hired on page 7, line [202].

The ATTC is a 25% to 30% refundable tax credit that applies to eligible expenditures incurred after May 18, 2004 in hiring qualifying apprentices in certain skilled trades during the first 36 months of the apprenticeship. Ontario corporations with a permanent establishment in Ontario and subject to Ontario corporate income tax are eligible for the tax credit.

A credit of 30% is available to corporations whose salaries and wages in the preceding taxation year were $400,000 or less. The ATTC is progressively reduced for corporations whose salaries and wages in the preceding taxation year were over $400,000 but less than $600,000. For corporations whose salaries and wages in the preceding taxation year were $600,000 or greater, the ATTC rate is 25%.

The maximum credit for each eligible apprentice is $5,000 per year, to a maximum of $15,000 over the first 36 months of the apprenticeship. The maximum annual tax credit of $5,000 is pro-rated for the number of days the apprentice is employed (with that employer) during the year.

Eligible apprentices should be in a qualifying skilled trade and must be hired before January 1, 2008. Qualifying skilled trades include designated construction, industrial and motive power trades, as well as the service trades eligible under the present apprenticeship component of the CETC.

Eligible expenditures are salaries and wages, including taxable benefits, paid after May 18, 2004 and before January 1, 2011 to an eligible apprentice, less any related government assistance received in respect of the eligible apprentice.

For additional information on the ATTC and for a list of qualifying skilled trades, refer to Interpretation Bulletin 3020R dated May 2006.

Corporate Minimum Tax (CMT)(Page 8)

Attach CT23 schedule 101 if your Total Assets exceed $5,000,000 or Total Revenue exceeds $10,000,000. These amounts include the aggregate of the total assets and total revenue of any associated corporation. These amounts also include the corporation's, and/or any associated corporation's, share of any partnership/joint venture total assets and total revenue.

Corporations that are subject to CMT are required to file financial statements in accordance with GAAP (Refer to Information Bulletin 4002R1 dated November 2003). Your corporation is exempt from CMT if it is:

  • an investment corporation as referred to in s.47
  • a mutual fund corporation, or non-resident-owned investment corporation as referred to in s.49, or
  • a communal organization, a corporation exempt from income tax or a non-resident corporation that is subject to Ontario income tax only because it disposed of taxable Canadian property situated in Ontario.

Corporations subject to the CMT should DFILE (Refer to Information Bulletin 4003R1 dated May 2004). Corporations which are unable to obtain the necessary software package to DFILE, may file their tax return using the Ministry of Finance's pre-printed CT23. Complete Schedule 101 only if the corporation is subject to the CMT.

Corporations that are exempt from CMT, or are not subject to CMT in the year and are not applying a CMT credit, do not need to submit the CT23 Schedule 101.

For purposes of CMT, the calculation of the CMT base includes adjustments for elections filed under sections 85 and 97 of the federal Income Tax Act (ITA) and for application of section 85.1 of the ITA. Where such adjustments are applicable, s.57.9 of the Act requires corporations to jointly elect in the form approved by the minister. The minister will consider a letter that specifically states that the parties are electing under s.57.9 of the Act; the letter contains the names and accounts numbers of both the transferor and transferee; is signed and dated by the transferor and transferee; and contains a calculation of the adjustment to the CMT base. Where applicable, a copy of the federal election should also be filed.

Capital Tax (Pages 9 to 13)

On page 12, line [543], enter the total amount of the corporation's Capital Tax as calculated.

Attach the following, if applicable:

  • If your corporation is a member of a partnership or has contributed assets to a joint venture, schedules showing the corporation's share of the paid-up capital, eligible investments, total assets and gross revenue of all partnerships and joint ventures. The forms 'Paid-up Capital - Partnerships/Joint Ventures', 'Eligible Investments - Partnerships/Joint Ventures' and 'Share of Total Assets - Partnerships/Joint Ventures' can be obtained by calling the ministry at the telephone numbers on page 2 of this guide or by downloading from our website: ontario.ca/finance.
  • Supporting computations for any additions or deductions from Total Paid-up Capital page 9, lines [361] and [371], and Total Assets page 10, line [443].
  • List of all corporate names, amounts and types of investments claimed as Eligible Investments, page 9, lines [402] to [406].

Exemption from Capital Tax

Unassociated corporations with both total assets and gross revenues of not more than:

  • $1 million, for taxation years ending prior to January 1, 2001;
  • $1.5 million, for taxation years ending after December 31, 2000 and commencing before October 1, 2001;
  • $ 3 million, for taxation years commencing after September 30, 2001

are exempt from capital tax and from the requirement to calculate taxable paid-up capital.

Family farm corporations, family fishing corporations, credit unions that are prescribed not to be financial institutions and certain mutual insurance corporations are exempt from capital tax effective for taxation years ending after May 4, 1999. (Please refer to page 22 of this guide for details of the capital tax exemption for credit unions that are financial institutions.)

General Capital Tax Rate and the Elimination of Capital Tax by 2012

The table on Page 5 of this guide provides for the plan to gradually eliminate capital tax by 2012. Starting January 1, 2005, the $5 million deduction from taxable capital will be increased by $2.5 million each year until it reaches $15 million on January 1, 2008. Starting January 1, 2009, the general capital tax rate of 0.3 per cent will be reduced each year by .07 per cent until the capital tax is fully eliminated on January 1, 2012.

Taxable Capital Deduction (TCD)

For taxation years ending after September 30, 2001, taxable capital is reduced by the TCD. The TCD amount is as follows:

Applicable Period Taxation year ending – TCD
after Sept 2001 and before Jan 1, 2005 $ 5 million
after Dec 31, 2004 and before Jan 1, 2006 $ 7.5 million
after Dec 31, 2005 and before Jan 1, 2007 $ 10 million
after Dec 31, 2006 and before Jan 1, 2008 $ 12.5 million
after Dec 31, 2007 and before Jan 1, 2012 $ 15 million

The mechanics of the calculation of the TCD does not result in a reduction in taxable capital but in a reduction in the capital tax.

Deduction from Taxable Paid-up Capital

If the corporation is associated with other corporations that have permanent establishments in Canada and the taxable paid-up capital of the associated group is less than the TCD, the deduction is equal to the corporation's taxable paid-up capital. If the taxable paid-up capital of the associated group is greater than the TCD, the deduction is equal to:

TCD x Taxable paid-up capital of the corporation
Taxable paid-up capital of the associated group

Effective January 1, 2003, an 'alternative method' to allocate the TCD among a group of associated corporations was introduced. The alternative method allows the group of associated corporations to instead elect to use the group members' total assets in the previous year to allocate the TCD among the associated group. However, once an election is made, each corporation within the associated group must determine its share of the TCD in accordance with the election. For a non-resident corporation, its total assets in Canada shall be deemed to constitute its total assets for such purposes.

If the corporation chooses to make the election, check box 524 on page 11 and complete CT23 Schedule 591 for the applicable year.

Notes:

  1. Connected Partnerships

    Corporations that are members of a connected partnership may be required to make an adjustment when determining the reduction to which they are entitled. Generally speaking, two partnerships are connected when more than 50% of the income or loss of one of the partnerships is allocated to a particular person or particular group of persons and more than 50% of the income or loss of the other partnership is also allocated to the particular person, particular group of persons or a corporation that is associated with the particular person or any member of the particular group of persons. Corporations should contact the Corporations Tax Section of the Advisory Services and Program Policy Branch at 905 433-6513 for instructions on calculating the adjustment.

  2. Short Taxation Year

    Capital tax payable is prorated for corporations that have taxation years of less than 365 days. The proration is accomplished by multiplying the capital tax otherwise payable by the ratio of the total number of days in the taxation year to 365.

  3. Floating Taxation Year

    A floating taxation year refers to a taxation year that does not end on the same date each year. For example, a corporation may have a floating taxation year that ends on the last Saturday in December each year. As a result, in 2000 the number of days in such a corporation's taxation year would be 371 days and in 2001 would be 364 days. These situations, and in similar situations are considered to be full taxation years. In cases where the taxation year is less than 365 days, solely as a result of a floating taxation year, it is not considered to be a short taxation year and capital tax would not be reduced. If a corporation, which normally has a floating taxation year, has a short taxation year the corporation would use 365 days (no adjustment for a leap year).

    Corporations with a floating taxation year where more than one capital tax rate is applicable and a proration calculation based on the number of days in a period is required must use the actual number of days in the floating taxation year and not 365 to compute the proration.

Capital Tax: Financial Institutions (Page 13)

Financial institutions are required to complete the capital tax calculation for financial institutions on page 13. These financial institutions are required to calculate capital tax in accordance with Division B.1. Schedules detailing the calculations for the amounts used on page 13, lines [565] and [570] should be retained by the financial institution.

A financial institution is defined to include:

  • banks
  • registered securities dealers
  • mortgage investment corporations
  • credit unions (other than a central credit union or league prescribed by regulation)
  • corporations authorized under the laws of Canada or a province to accept deposits from the public and carry on the business of lending money
  • corporations that are authorized under the laws of Canada or a province to carry on the business of offering their services as a trustee to the public, and
  • any other corporation which is prescribed by regulation to be a financial institution.
Authorized foreign banks

In line with changes to the ITA, 'authorized foreign banks' must pay capital tax effective from June 28, 1999. An authorized foreign bank is defined by section 2 of the Bank Act and in general terms is a foreign bank authorized to operate in Canada through a branch. Paid-up capital of an authorized foreign bank is computed in the same manner as for the federal large corporations tax. The investment allowance of an authorized foreign bank is computed in the same manner as for other financial institutions under the Act with two exceptions: First, an investment made by an authorized foreign bank is not eligible if the investee corporation is exempt from capital tax. Second, an authorized foreign bank does not qualify for the full investment allowance discussed under 'Investments in Related Financial Institutions'.

Capital Tax Rates - Financial Institutions

The rates of capital tax payable by financial institutions (excluding credit unions) are:
    Taxable Capital over $400 million
Applicable Period First $400 million of Taxable Capital non-deposit taking deposit taking
Prior to Jan 1, 2009 .6 .72 .9
Jan 1, 2009 .45 .54 .675
Jan 1, 2010 .3 .36 .45
Jan 1, 2011 .15 .18 .225
Jan 1, 2012 eliminated

The 2006 Ontario Budget proposed to cut the current capital tax rates by 5 per cent, each year effective January 1, 2007. Refer to Information Bulletin 6013 for further information.

Taxable Capital Deduction (TCD)

The TCD discussed on page 21 for regular corporations also applies to financial institutions.

Where the financial institution is not related at any time in the taxation year to another corporation that is a financial institution with a permanent establishment in Canada and that is not exempt from capital tax by virtue of s.71 (1) of the Act, the financial institution receives the entire deduction.

Where the financial institution is related, the deduction is prorated by multiplying it by the fraction obtained in dividing the financial institution's taxable capital employed in Canada for the taxation year by the aggregate amount of taxable capital employed in Canada by all related financial institutions with permanent establishments in Canada that are not exempt from capital tax by virtue of s.71(1).

Credit Unions that are Financial Institutions

Effective May 5, 1999, credit unions that are financial institutions are exempt from capital tax. For taxation years straddling May 4, 1999, the amount of capital tax payable will be the tax determined using the rules and rates as they read on May 4, 1999 multiplied by the ratio of the number of days in the taxation year that are before May 5, 1999 to the total number of days in the taxation year.

The rates of capital tax payable by credit unions that are financial institutions for taxation years commencing before May 5, 1999 are:

  • 0.05% of taxable paid-up capital for the ratio that the number of days in the taxation year after December 31, 1997 and before January 1, 1999 are, to the total number of days in the taxation year multiplied by the corporation's Ontario allocation factor; and
  • 0.1% of taxable paid-up capital for the ratio that the number of days in the taxation year after December 31, 1998 and before May 5, 1999 are, to the total number of days in the taxation year multiplied by the corporation's Ontario allocation factor.

Investments in Related Financial Institutions

Effective on or after May 7, 1997, a financial institution is allowed to claim a full investment allowance for investments in shares and long-term debt of related financial institutions and insurance corporations in Canada, whether or not they have a permanent establishment in Ontario, provided that the financial institution claiming the investment allowance allocates all its capital to Ontario and is not controlled directly or indirectly by another financial institution. This full investment allowance does not apply to a financial institution that is an authorized foreign bank.

Small Business Investment Tax Credit (SBITC) for Financial Institutions

The SBITC allows certain financial institutions and credit unions to reduce their capital tax liability by making eligible investments to qualifying small businesses. The credit includes a 30% tax credit for investments in the equity capital of Community Small Business Investment Fund Corporations (CSBIFCs) that are made after May 6, 1997 and before January 1, 2004.

An additional 30 % tax credit may be claimed by a financial institution when the CSBIFC reinvests the capital in eligible investments under the Community Small Business Investment Funds Act in the taxation year. In order to claim the tax credit, in respect of investments made in CSBIFCs, a financial institution must obtain an approval letter by applying in writing to:

Manager, Business Investment Plans Section
Income Tax Related Programs Branch
Ministry of Finance
PO Box 624
33 King Street West
Oshawa ON  L1H 8H5

The approval letter must be attached to the CT23 for the year in which the tax credit is claimed.

Premium Tax (Page 13)

Uninsured Benefit Arrangements

Complete this section if you administer Ontario-related Uninsured Benefit Arrangements (UBA) and are liable to collect and remit premium tax related to the UBA. This provision applies to corporations and to unincorporated entities.

If reporting UBA premiums, enter the amount of UBA premiums on page 13, line [587] and the related amount of premium tax on page 13, line [588]. Insurance corporations should use the CT8 tax return to calculate this tax.

If an UBA plan has more than one administrator at the same time, an administrator may file an election in a letter form with its CT23 to account for all tax owing for the plan. The letter must include the name of the plan, names and addresses of all administrators of the plan, and a certification that all tax has been accounted for during the period covered by the election.

If partners of a partnership are each administrators of the same plan, the partners may wish to account for their UBA liability for the taxation year by filing a joint CT23 for their UBA tax only. A letter signed by each partner, must be filed with each joint return certifying that the partners' UBA liability has been reported in full for the taxation .year

Insurance Placed With Unlicenced Insurer

Complete this section if you are:

  1. an Insurance Broker who currently files a CT23 and who has placed an insurance contract with an unlicenced insurer, or
  2. a corporation that has purchased insurance directly from an unlicenced insurer.

Enter the total premium tax on premiums paid in the taxation year on page 13, line [588]. Attach a schedule to the CT23, showing the calculation of the premium tax.

Premium tax on insurance placed with unlicenced insurers is collected under the Corporations Tax Act for premiums paid to a broker during its taxation year commencing after 1997, and for premiums paid directly by a corporation after 1997.

Reconciliation of Net Income (Loss) for Federal Tax Purposes to Ontario (if different) (Page 14 and 15)

The reconciliation of federal net income for tax purposes from federal Schedule 1 to net income for Ontario purposes is to be prepared whenever items included in income or deductions allowed for Ontario tax purposes differ from those used in computing net income for federal tax purposes.

Some of the more common differences resulting in adjustments on the reconciliation schedule are Capital Cost Allowance, Cumulative Eligible Capital, and Reserves. Since these are often discretionary deductions taxpayers may choose to claim different amounts for Ontario and federal tax purposes.

Resource Allowance (lines [609], [617] and [659] )

The 2004 Ontario Budget announced that Ontario would not parallel the federal measure, introduced in the 2003 federal budget, that replaces the 25% resource allowance with a deduction for Crown royalties and mining taxes paid (the resource allowance is actually being eliminated gradually at the federal level over a five year period starting January 1, 2003, and a deduction for provincial and other Crown charges is being phased in over the same five-year period). Corporations will, therefore, be able to claim the full amount of the resource allowance for Ontario tax purposes.

A corporation may claim the resource allowance with respect to profits earned through a partnership where the partnership does not deduct Crown royalties and mining taxes in computing its income. Oil and gas companies can claim depletion deductions from earned depletion pools generated before 1990.

Enter the amount of federal resource allowance deducted on line [609].

Enter the amount of Crown charges deducted for federal purposes on line [617].

Enter the Ontario resource allowance claimed on line [659]. Attach schedule showing calculation.

Other Adjustments

For taxation years beginning after May 6, 1997, income computed for Ontario purposes must be used in determining Ontario resource profits. This will prevent corporations from obtaining a double benefit as a result of claiming both an Ontario incentive deduction and an additional resource allowance on that incentive.

Management fees (line [613])

Subsection 11(5) includes in income a designated fraction of management fees, rents, royalties and similar payments which are paid or payable to a non-resident person or non-resident owned investment corporation with who the corporation is not dealing at arm's length. For more information see Interpretation Bulletin 3004

The following schedule provides details of these rates and the effective date for each. If a taxation year straddles more than one rate period, a proration of each applicable rate will be required based on the ratio that the days in the taxation year that fall within a specific rate period are to the total days in the taxation year.

Add-Back Rate Applicable Period
5/12.5 2003 calendar year
5/14 2004 calendar year and thereafter

Royalties (Page 14)

Effective May 4, 1999, the following royalties will no longer be subject to the 5/15.5 add-back rule. Amounts paid or payable to a non-arm's length non-resident person or a non-arm's length non-resident owned investment corporation:

  • for the use or right to use computer software in Canada; or
  • for the use or right to use patents or information concerning industrial, commercial or scientific experience (know-how), including designs, models, plans, formulas and processes in Canada.

This is regardless of whether a tax treaty exempts the royalty from federal withholding taxes under the federal Income Tax Act (ITA).

This change is effective for amounts which are deducted and are payable by a corporation for a taxation year ending after May 4, 1999.

Incentives for New Electricity Supply

(Page 14)

On November 12, 2002, Ontario proposed several incentives to increase the supply of electricity generated from alternative or renewable sources. However, legislation was recently introduced repealing some of those tax incentives that have not been fully implemented, including the 10-year corporate income tax tax holiday (section 13.6 deduction from income) as well as the immediate 100% write-off for investments in qualifying energy-efficient equipment.

Depreciable Property - Fast Write-off Incentive (line [675])

New investments in qualifying assets used to generate electricity from alternative or renewable sources of energy, acquired after November 25, 2002 and before January 1, 2008, would be eligible for a 100% write-off in the year of acquisition. The Minister of Energy or their delegate may determine which property qualifies for the fast write-off.

Ontario Current Cost Adjustment (OCCA)

The OCCA deduction is an incentive to assist corporations with the costs involved in purchasing new pollution control equipment for use in Ontario. Corporations are entitled to a one-time deduction in computing Ontario taxable income in respect of the 'eligible cost' to the corporation of all 'eligible assets' acquired by the corporation for the taxation year. The deduction is in addition to the capital cost allowance (CCA) deductions allowed for federal and Ontario income tax purposes. For more information see Interpretation Bulletin 3005.

Ontario Research and Development Expenditures Deduction

In 2001 Ontario introduced the Ontario Scientific Research and Experimental Development deduction that replaced the R & D Super Allowance.

The new initiative allows corporations to exclude from taxable income for Ontario purposes, the amount of the federal ITC's relating to eligible Ontario Scientific Research and Experimental Development expenditures.

To claim the Super Allowance Replacement Deduction complete Schedule 161 and enter the amount on line [679].

Ontario New Technology Tax Incentive (ONTTI)

The ONTTI is effective for taxation years ending after May 6, 1997. It allows an immediate write-off, by way of 100% of capital cost allowance, for the cost of qualifying intellectual properties acquired in the course of an intellectual property transfer. Qualifying Intellectual Property includes such things as patents, licences, know-how and other similar property constituting knowledge. The intellectual property must be used primarily for the purpose of implementing in Ontario an innovation or invention in a business carried on in Ontario. The maximum expenditure allowed in a year is $20 million. For further information see Tax Legislation Bulletin 98-12.

Workplace Child Care Tax Incentive (WCCTI)

(Page 15, line [666])

The Workplace Child Care Tax Incentive (WCCTI) is a 30% deduction of qualifying capital cost expenditures, incurred by a corporation to construct new on-site licensed child care facilities in Ontario, to renovate existing facilities in Ontario or for contributions made to an unrelated party for these types of expenditures.

The corporation must obtain from the child care operator written confirmation that the money or qualified contributions are used for the purposes of constructing or renovating a child care facility or for the acquisition of playground equipment. The child care operator must provide the corporation with its licence number under the Day Nurseries Act.

Corporations which allocate part of their taxable income to other jurisdictions are entitled to 'gross-up' the WCCTI deduction to ensure that the full benefit of the deduction is realized.

The WCCTI is allowed on eligible expenditures incurred after May 5, 1998 and before January 1, 2005.

For additional information on the WCCTI refer to Tax Legislation Bulletin, Number 99-2, dated August 1999.

Workplace Accessibility Tax Incentive (WATI)

(Page 15, line [668])

The Workplace Accessibility Tax Incentive (WATI) provides a deduction in respect of qualifying expenditures incurred after July 1, 1998 and before January 1, 2005. The WATI can only be claimed once on a particular qualifying expenditure and is in addition to other deductions available for income tax purposes in respect of the qualifying expenditures. The amount of the WATI for a corporation or partnership of which the corporation is a member, during a particular taxation year is the total of:

  1. the expenditures incurred to provide the support services of a sign language interpreter, an intervenor, a note-taker, a reader or an attendant, during a job interview in Ontario; and
  2. qualifying expenditures up to a maximum of $50,000 per qualifying employee, other than the qualified expenditures included in the amount determined under paragraph 1 above.

The maximum of $50,000 per qualified employee is reduced by any qualified expenditures incurred in a prior taxation year, in respect of the qualifying employee which were included in determining a WATI deduction in that prior year. Corporations with allocation to other jurisdictions are entitled to 'gross-up' the WATI to ensure that the full benefit of the deduction is realized. A corporation or partnership making a WATI deduction must keep as part of their books and records a copy of the certificate or relevant documentation on which the corporation is relying in claiming that the employee is a qualifying individual.

For additional information on the WATI refer to Tax Legislation Bulletin, Number 99-1, dated August 1999.

Ontario School Bus Safety Tax Incentive (OSBSTI)

(Page 15, line [671])

The Ontario School Bus Safety Tax Incentive (OSBSTI) is a 30% deduction of the capital cost of acquiring a new school bus. The school bus must be included in class 10 of Schedule II of the regulations for purposes of the ITA. The OSBSTI can only be claimed once in respect of the acquisition and is in addition to the deduction available for income tax purposes with respect to the capital cost allowance. For a multi-jurisdictional corporation, the incentive is grossed up by the corporation's Ontario allocation factor. A new school bus eligible for the incentive is one defined under subsection 175(1) of the Highway Traffic Act that conforms to the CSA standard D250-M 1998. The school bus must be used primarily to transport students to and from school in Ontario. It must be acquired after May 4, 1999 and before January 1, 2006.

For additional information on the OSBSTI refer to Tax Legislation Bulletin, Number 003, dated June 2000.

Educational Technology Tax Incentive (ETTI)

(Page 15, line [673] )

The Educational Technology Tax Incentive (ETTI) is a 15% deduction calculated on the amount of a price discount given or a donation made after May 2, 2000 and before January 1, 2005, to an eligible Ontario community college or eligible Ontario university with respect to new eligible teaching equipment and new eligible learning technologies.

The ETTI is available to corporations and to a corporation that is a general partner in a partnership where the partnership has made the price discount or donation.

In order to claim this incentive the corporation must obtain a certificate issued by the eligible educational institution which received the donation or price discount stating that the equipment or technology meets the conditions of eligibility for the ETTI. The certification form must be retained by the corporation in order to claim this incentive. The certificate should not be submitted with the corporation's tax return.

If claiming the ETTI enter the total eligible amount for donations and price discounts in line [672] on page 15 of the CT23 return.

The amount of ETTI claim should be entered in line [673] and will be 15% of the amount in line [672] for corporations operating only in Ontario (100% allocation to Ontario). For multi-jurisdictional corporations (less than 100% allocation to Ontario) the amount in line [672] must be grossed up by dividing it by the corporation's Ontario allocation factor. The 15% incentive is then taken on the grossed up figure and entered in line [673].

For additional information on the ETTI refer to Tax Legislation Bulletin, Number 01-07, dated June 2001.

Tax Incentive for Investing in Ontario Jobs and Opportunity Bonds (Page 15, line [664])

The tax incentive to which a corporation is entitled under subsection 37.1(2) of the Act in respect of the interest received or receivable by it on an Ontario Jobs and Opportunity Bond in a taxation year is the amount of interest received or receivable which is otherwise to be included in income under section 12 and subsection 20(14) of the ITA less any accrued interest otherwise deducted under subsection 20(14) of the ITA.

Bonds are often sold between interest dates so that at the time of transfer from the transferor to the transferee, some interest has accrued. Under subsection 20(14) of the ITA, if the transferee corporation includes the total interest received in its income then it may deduct the portion of interest accrued prior to the transfer.

Continuity of Losses Carried Forward - Analysis of Balance by Year of Origin (Page 16)

Complete these schedules whenever losses are incurred or losses are carried forward.

Ontario parallels the federal measure that extends the loss carry-forward period for non-capital losses from 7 to 10 years, for losses that arise in taxation years that end after March 22, 2004.

The 2006 Ontario Budget proposes to parallel the Federal measure to extend the carry-forward period for non-capital losses from 10 to 20 years. See Bulletin 6013 for further details.

Note: Commencing with the 2001 CT23 tax return capital losses are now shown at 100% of losses (before applying inclusion rate).

Request for Loss Carry-back (Page 17)

Complete this schedule if the corporation is carrying back a non-capital, net-capital, farm or restricted farm loss. The onus is on the taxpayer to substantiate any loss being carried back to a prior year.

Summary of Taxes Payable (Page 17)

In the summary section, bring forward the amounts of Income Tax, Corporate Minimum Tax, Capital Tax and Premium Tax and enter the total on page 17, line [950]. Enter payments made on page 17, line [960]. Mutual fund corporations may enter their Ontario Capital Gains Refund amount on page 17, line [965]. Corporations may enter their QET on page 17, line [985]. If claiming the Specified Tax Credits, enter the unapplied amount (see Specified Tax Credits section) on page 17, line [955].

If you are requesting a refund:

  • for the full overpayment, complete line [975]. Any related credit interest will also be refunded;
  • and you want the total overpayment, including any related credit interest, to be applied to a particular taxation year, complete the 'Apply to' field but leave line [980] blank;
  • and you want to apply a specific amount to a taxation year, complete the 'Apply to' field and put the amount in line [980]. Any remaining balance will be refunded.

The capital gains refund of a mutual fund corporation for taxation years ending after February 27, 2000 is adjusted to reflect changes to the rate at which capital gains are included in income (66 2/3% for capital gains realized after February 27, 2000 and 50% for capital gains realized after October 17, 2000) and changes to the corporate income tax rate (see page 13 of this guide).

Certification (CT23) (Page 17)

Complete the 'Certification' section by providing the name, address, and title of the authorized signing officer of the corporation. Be sure to sign and date the CT23.

The Annual Return (MGS)

The Annual Return is comprised of page 1 of the combined CT23 Corporations Tax and Annual Return and either of MGS Schedule A or MGS Schedule K (page 18, 19 or 20). The information provided on these pages is collected under the authority of the Corporations Information Act for the purpose of maintaining a public database of corporate information. The Ministry of Finance (MOF) is collecting this information on behalf of the Ministry of Government Services (MGS). This collection process applies to corporations that have a taxation year ending on or after January 1, 2000.

If you answer 'Yes' to the question below, 'Is a MGS Annual Return Required?', most of the information on page 1 of the combined return and where applicable, MGS Schedule A or MGS Schedule K, will be provided to MGS by the MOF. Authority for providing this information is given pursuant to subsection 98(4) of the Corporations Tax Act.

Is A MGS Annual Return Required?

Every corporation that is incorporated, amalgamated or continued in Ontario under the Business Corporations Act, Ontario must file an Annual Return. This type of corporation is referred to as an 'Ontario Corporation'.

Every foreign corporation which has a licence endorsed under the Extra-Provincial Corporations Act to carry on business in Ontario must file an Annual Return. Foreign extra-provincial corporations are those corporations that are incorporated, amalgamated or continued outside Canada. This type of corporation is referred to as a 'Foreign Business Corporation'.

If neither of the above applies to the corporation then please answer 'No' to the question 'MGS Annual Return Required?'.

If one of the above conditions does apply but the corporation has filed the Annual Return electronically to MGS, then the corporation's response to the question will be 'No'.

Note: A corporation that is incorporated, continued, or amalgamated in a Canadian jurisdiction other than Ontario is not required to file an Annual Return.

How Can You File?

The following methods are available to file the Annual Return:

  • Complete and submit the combined preprinted paper CT23 and Annual Return or the Annual Return and EFF Declaration to the Minister of Finance at the address indicated on the top of page 1 of these documents.
  • Complete the electronic filing version of the Annual Return directly with the Ministry of Government Services. For information on this filing option, refer to the ServiceOntario website at ontario.ca/cnh4. If applicable, the corporation would submit its CT23 to the Minister of Finance separately.

When Must You File?

A corporation with share capital that is required to deliver a CT23 (or is EFF) and an Annual Return, is required to file the Annual Return within six months after the end of its taxation year. This applies whether the Annual Return is delivered to the MOF or electronically to MGS.

A corporation is only required to file one Annual Return in a calendar year. This return is due at the time the first CT23 is required to be delivered to the MOF during the calendar year. A corporation's CT23 is required to be delivered on or before the last day of the sixth month after the end of the taxation year.

The Annual Return will be considered delivered on the date it is received by the MOF. The effective date of filing for the Annual Return is the date the information is updated in the Ontario Business Information System (ONBIS). The effective date of filing for the CT23 is the date the MOF receives it.

If the Annual Return is filed electronically during MGS business hours, the date of receipt will be considered to be that day. Otherwise, the date of receipt will be the next business day of MGS.

An Annual Return is considered filed if it is complete and has been recorded in the ONBIS.

Incomplete Annual Returns are considered to be deficient. MGS will contact corporations regarding Annual Return deficiencies. The Annual Return will not be considered filed until the deficiency is corrected.

What Must You File?

Ontario Corporations must complete all of the information on page 1 of the combined CT23 Corporations Tax and Annual Return. MGS Schedule A will only be required if there has been a change in the information previously submitted to MGS with regard to the Directors, Officers, or Administrators of the corporation.

Foreign Business Corporations must complete all of the information on page 1 of the combined CT23 Corporations Tax and Annual Return and MGS Schedule K. MGS Schedule K will only be required if there has been a change in the information previously submitted to MGS with regard to Chief Officer/Manager or Agent for Service.

All information in the Annual Return must be current as of the date of delivery to the MOF or to the MGS.

Each corporation must keep an up-to-date paper or electronic record of the prescribed information set out in the return available for examination at its registered office or principal place of business in Ontario.

Note: If you are filing a CT23 or are claiming an exempt from filing (EFF) status please refer to the beginning of this guide for information on completion and filing requirements.
