Employer Health Tax

Ontario taxes and COVID-19. Learn more.

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

The Ontario government has increased the EHT exemption for 2020 from $490,000 to $1 million due to the special circumstances caused by the coronavirus (COVID‑19) in Ontario. In the 2020 Ontario Budget, the government announced it was making the EHT payroll exemption increase permanent.

The EHT exemption is indexed to inflation every five years and the next adjustment had been scheduled for 2024. Given the doubling of the exemption threshold starting in 2020, the government moved the next scheduled adjustment for inflation to January 1, 2029.

To be able to claim the tax exemption, employers must be eligible employers as defined under the EHT Act. Employers who have a municipal representative on their board of directors, or who are under the control of any level of government, are generally not eligible employers.

Employers normally cannot claim the exemption if their Ontario payroll for the year (including the payroll of any associated employers) is over $5 million. However, eligible employers who are registered charities can claim the exemption even if their payroll exceeds $5 million.

Effective January 1, 2017, special rules apply to eligible employers who are registered charities.

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

Do I need to register for EHT?

You need to register with the province if you are an employer and you are:

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.

Ontario Payroll (Total 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 $1.2 million (starting in 2021)

Starting in the 2021 tax year, employers with an annual Ontario payroll over $1.2 million have to make monthly employer health tax instalment payments.

This means, starting in 2021, all employers should begin remitting monthly instalments as soon as their annual payroll exceeds $1.2 million.

Employers with an annual Ontario payroll of $1.2 million or less do not need to make instalment payments.

Prior to 2021, employers were required to make monthly instalment payments when their annual Ontario payroll exceeded $600,000.

Please see the Guide for Employers for more information and examples of instalment obligations.

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. Once you submit a nil return, the ministry will stop sending you annual returns automatically. It is the employer’s responsibility to contact the ministry when changes occur that affect your requirement to file an EHT return.

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.
