Employer Health Tax

Employer Health Tax (EHT) is a payroll tax on remuneration paid to employees and former employees.

A regulation that would provide special rules applicable to eligible employers who are registered charities and to employers who are associated with registered charities is proposed to come into effect January 1, 2017.

As part of the regulation development process, we invite you to review the Notice of intention to bring forward an Ontario Regulation under the Employer Health Tax Act Regarding Special Rules for Registered Charities and have your say by clicking on that web page's 'Comment on this proposal via email' button.

The EHT exemption increased to $450,000 from $400,000 of Ontario payroll.

Private sector employers with annual Ontario payrolls over $5 million, including groups of associated employers [PDF], are no longer eligible for the exemption.

Registered charities, including those with payrolls over $5 million, continue to be eligible for the exemption.

Do I have to pay EHT?

You have to pay Employer Health Tax if you are an employer and you:

  • have employees who physically report for work at your permanent establishment in Ontario, or
  • have employees who are attached to your permanent establishment in Ontario, or
  • have employees who do not report to work at any of your permanent establishments but are paid from or through your Ontario permanent establishment, and
  • have Ontario payroll in excess of your allowable exemption amount.

Tax rates

The EHT rates vary from 0.98% on Ontario payroll less than $200,000, up to 1.95% for payroll in excess of $400,000.

The amount of EHT you, as an employer, pay is calculated by multiplying your Ontario payroll for the year – after deducting any tax exemption – by the applicable tax rate. The tax rate is based on the Ontario payroll of the employer before deducting any tax exemption.

Total Ontario remuneration Rate
Up to $200,000.00 0.98%
$200,000.01 to $230,000.00 1.101%
$230,000.01 to $260,000.00 1.223%
$260,000.01 to $290,000.00 1.344%
$290,000.01 to $320,000.00 1.465%
$320,000.01 to $350,000.00 1.586%
$350,000.01 to $380,000.00 1.708%
$380,000.01 to $400,000.00 1.829%
Over $400,000.00 1.95%
  • The tax rate for a multiple account employer is based on the combined Ontario payroll of all the employer's accounts.
  • The tax rate for an associated employer is based on the Ontario payroll for that employer.

For example, an employer with $175,000 of Ontario payroll, and who does not have any tax exemption, would have a tax rate of 0.98%, and would pay EHT of $1,715 for the year.

Instalment payments: Ontario payroll over $600,000

Employers with an annual Ontario payroll over $600,000 have to make monthly employer health tax instalment payments.

Employers who are eligible for a tax exemption, and who have Ontario payroll over $600,000, have to make monthly instalments as soon as their payroll exceeds their allowable exemption amount.

Employers with an annual Ontario payroll of $600,000 or less do not need to make instalment payments.

How do I file an EHT return?

The Ministry of Finance will mail you a personalized annual return. If you did not receive a return, you should contact the Ministry of Finance. You should also contact the ministry when your Ontario payroll for the year exceeds your allowable exemption amount.

If you receive an annual return, you must complete it and send it to the ministry, even if no EHT is payable. If you are not an associated employer, once you submit a nil return, the ministry will stop sending you annual returns automatically.

You can also file your return online, using ONT-TAXS online.

Special returns (Remuneration paid once a year)

Employers who pay their entire Ontario payroll in one month need to file a special EHT return within 15 days following the month in which the payroll was paid. Eligible employers are required to file a special return if their Ontario payroll in one month exceeds their available exemption amount.

Final returns

Employers who amalgamate, cease to have a permanent establishment in Ontario, or who are ceasing operations in Ontario, are required to file a final return within 40  days of ceasing operations. For most employers, 'ceasing operations' would likely be the last date of payroll.

Due dates

  • Annual returns are due March 15th of the following calendar year.
  • Special returns are due on the 15th of the month after the payroll was paid.
  • Final returns are due 40 days after your business closes or the amalgamation date.

Note: Financial institutions are not authorized to accept or process employer health tax returns.
