For taxation years ending after December 31, 2008, corporations are required to file a harmonized T2 Corporation Income Tax Return with the Canada Revenue Agency (CRA). The harmonized tax return includes the following Ontario corporation taxes:
However, the harmonized tax return does not include the Ontario Insurance Premium Tax (Premium Tax). For taxation years ending in 2009 and 2010, corporations subject to Premium Tax previously filed the Insurance Premium Tax Return with the Ontario Ministry of Finance (the ministry). For taxation years ending in 2011 and beyond, corporations will file the new CT - Insurance Premium Tax Return (the tax return) with the ministry.
Generally, insurance corporations carrying on business through a permanent establishment and other entities liable to calculate, collect and remit Premium Tax under the Act in Ontario are liable to pay Premium Tax and must file the tax return. This includes incorporated and unincorporated entities such as:
A completed tax return and supporting documents must be submitted on or before the last day of the sixth month after the end of the taxation year. If the return is filed late, a penalty may be imposed.
For taxation years ending in 2009 and later, taxpayers may use ONT‑TAXS online to file, pay and view the tax return.

Payments and credits are first applied against any tax owing, second against any penalty owing, third against any interest owing, and fourth against any other amounts owing.
Instalments are not required to be made by an insurance exchange, or under the following circumstances:
Instalments may be paid quarterly (every three months) if the Premium Tax for the current taxation year or the previous taxation year is equal to or greater than $2,000 and less than $10,000. Quarterly instalments should be calculated according to one of the following three methods:
Instalments must be paid monthly if the Premium Tax for both the current taxation year and the previous taxation year are each $10,000 or more. Monthly instalments should be calculated according to one of the following three methods:
The use of the first method requires estimating the Premium Tax in the current taxation year. Where the instalments made using the first method are less than the actual tax payable, interest may be assessed on any deficiency in the instalment account.
When calculating instalments for a previous year that has less than 365 days, the Premium Tax for that previous year must be grossed up to 365 days. Furthermore, if a previous year has less than 183 days, the Premium Tax for that previous year is the greater of the:
A corporation that is the successor corporation of amalgamated corporations must use the total predecessor corporations' Premium Tax in the computation of instalments.
A corporation that is involved in a wind‑up or rollover must include the subsidiaries' Premium Tax or the transferor corporations' Premium Tax in the calculation of instalments.
For taxation years that end on the last day of a month, instalments (monthly or quarterly) are due by the last day of the following month or quarter. For taxation years that do not end on the last day of a month, instalments are due by the same day of the following month or quarter.
The difference between the current year Premium Tax 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 the taxation year, if your corporation was a Canadian‑controlled private corporation (CCPC) throughout the taxation year and the taxable income in the prior year was less than or equal to $500,000. The taxable income is grossed up to 365 days if the prior year has less than 51 weeks.
In all other cases, the balance of tax is due within two months after the end of your taxation year.
Interest is calculated and compounded daily for every day that there is a surplus or deficiency in a corporation's account. The corporation's account is divided, by period of time, into an instalment account and a tax account.
The instalment account begins on the first day of the taxation year and ends on the day before the balance of tax due date. The tax account begins on the balance of tax due date which is two months (or three months for a CCPC) after the end of the taxation year.
Interest on a surplus is allowed by the ministry at three percentage points below the base rate, and interest on a deficiency is payable by the corporation at three percentage points above the base rate. The base rate approximates the average prime rate of the major Canadian banks.
Along with unpaid Premium Tax, a deficiency in a corporation's account also includes interest, penalties and other unpaid amounts. If a tax return is not filed on time, no interest will be allowed on a surplus for the period from the day the tax return was required to be filed to the day the tax return is filed.
All records, documents and receipts pertaining to the tax return must be kept for seven years. For further information, please read about the Retention/Destruction of Books and Records.
The Identification Number is a unique number assigned by the ministry to your account and noted on your return.

A corporation may file its harmonized T2 Corporation Income Tax Return utilizing the functional currency reporting provisions in the federal Income Tax Act (the ITA).

Premium Tax is payable by an Ontario corporation that enters into or pays premiums under an insurance contract with an unlicensed insurer. Premium Tax is also payable by an Ontario individual who, through an Ontario insurance broker, enters into or pays premiums under an insurance contract with an unlicensed insurer.
An unlicensed insurer is an insurance corporation that is not licensed under the Insurance Act to carry on an insurance business in Ontario.
The insurance contract is in respect of property situated in Ontario or a person who is resident in Ontario, but does not include life insurance.
The premiums placed with unlicensed insurers should be reported on lines 10B, 10C and 10D as applicable, and the related Premium Tax reported on lines 13 to 16.
Premium Tax is payable in respect of a reciprocal or inter‑insurance exchange which is a group of subscribers exchanging reciprocal contracts of indemnity or insurance with each other through the same attorney.
Groups of subscribers are typically organizations such as hospitals, school boards, municipalities or law firms which provide self-insurance to the members of the group.
The premiums in respect of a reciprocal or inter‑insurance exchange should be entered on lines 11C and 11D as applicable, and the related Premium Tax reported on lines 14 to 16.
Insurance exchanges are not required to make instalment payments but must pay the Premium Tax by the balance of tax due date.
An Ontario administrator of a benefit plan, commonly referred to as an Uninsured Benefit Arrangement (UBA) is required to collect and remit Premium Tax. This requirement includes unincorporated administrators.
A UBA is a plan which gives protection against risk to individuals that could otherwise be obtained by taking out a contract of insurance. A UBA may be either funded or unfunded.
A UBA is a funded benefit plan if the contributions paid into it are in excess of the amounts required for the payment of benefits foreseeable and payable within 30 days. Any other UBA is an unfunded benefit plan.
Where a UBA is a funded benefit plan, Premium Tax is levied on the contributions paid into the plan by the planholder and the members. Where a UBA is an unfunded benefit plan, Premium Tax is levied on the benefits paid out of the plan. Furthermore, all UBAs are subject to Premium Tax on payments in respect of administration fees.
Under certain criteria, a qualifying trust that is a UBA may elect to be deemed an unfunded benefit plan where it would otherwise be a funded benefit plan.
The box Election filed under s.74.2 (3.1) of the CTA should be checked if the corporation is making this election.
The Premium Tax on UBAs should be reported on line 17.
In the calculation section, determine the total Premium Tax on lines 18 and 19, enter the payments made on line 20, and determine the net Premium Tax payable or refundable on line 21. If there is a refund and it should be applied to the next taxation year, check the box Apply credit to future reporting period.
If a paper tax return is filed, it must be signed and dated by an authorized signing officer. The information contained in the tax return must be true, correct and complete.

In order to discuss this tax return with a third party (such as your accountant or solicitor) the ministry requires proper authorization. An Authorizing or Cancelling a Representative form must be completed and returned to the ministry.
