Employer Health Tax (EHT)

Overview

The Employer Health Tax (EHT) is a payroll tax on remuneration (for example, salaries, wages, bonuses, taxable benefits, stock options etc.) that employers in Ontario provide to current and former employees.

The purpose of this tax is to assist in providing the government with revenue to fund health care in Ontario.

Who pays EHT

Employers are required to pay EHT on remuneration paid to employees who either:

• physically report for work at your permanent establishment in Ontario
• are attached to your permanent establishment in Ontario
• do not report to work at any of your permanent establishments but are paid from or through your Ontario permanent establishment

If your Ontario payroll is more than your allowable exemption amount, you will have to pay EHT .

You do not have to pay EHT if you are eligible to claim the exemption and your company’s annual Ontario payroll is below your exemption amount.

For detailed information, please visit the dedicated EHT webpages for Remuneration, Permanent Establishments, and Employer-Employee Relationship.

EHT exemption

The exemption amount is currently $ 1 million.

The exemption amount is scheduled for adjustment for inflation on January 1, 2029.

For 2020, the Ontario government increased the exemption amount from $490,000 to $1 million, due to the special circumstances caused by the coronavirus (COVID‑19) in Ontario. This increase was made permanent in 2021. For 2019, the exemption amount was $490,000 and for 2014 – 2018, it was $450,000.

You can claim the tax exemption if:

• you are an eligible employer as defined under the EHT Act
• you pay income taxes
• your Ontario payroll for the year (including the payroll of any associated employers) is less than $5 million or you are a registered charity
• you are not under the control of any level of government (e.g. your board of directors does not include any municipal representatives)

Eligible employers who are members of an associated group are required to enter into an agreement to share the tax exemption for the year using the Associated Employer Exemption Allocation form.

EHT tax exemption example

If you are an eligible employer with a total Ontario payroll of $1,800,000 per year, you would claim the exemption on the first $1,000,000 and pay EHT on the remaining $800,000 of your payroll for the year. Note that the tax rate you use is based on the level of your Ontario payroll before you have deducted any tax exemption.

Learn more about the EHT tax exemption and eligible employer scenarios.

Associated employers

Eligible employers who are members of an associated group must enter into an agreement to share the tax exemption for the year. Associated employers are connected by ownership or by a combination of ownership and relationships between individuals.

One employer in the group must complete an Associated Employers Exemption Allocation Form form on behalf of the whole group and submit it to the ministry with its annual return. If any associated employer is missing from this form or if the form is not submitted, all of the employers in the associated group will be denied the tax exemption. For 2014 and later years, no exemption can be claimed if the associated group’s combined annual Ontario remuneration (payroll) is over $5 million. Employers are required to complete an annual return for each account that has Taxable Ontario Remuneration.

Visit the Ministry of Finance’s Online Services Page to file and submit your Associated Employers Exemption Allocation Form online.

For detailed information about associated employers and filing rules, visit the Associated Employers webpage and related scenarios.

Registered charities

There are special EHT rules for registered charities. For detailed information, visit the Registered Charities webpage and related scenarios.

Tax rates and how to calculate EHT

Rates

Calculate your EHT

The tax rate you use is based on the level of your Ontario payroll before you have deducted any exemption. The EHT is calculated by deducting your  exemption from your total Ontario remuneration and then multiplying that amount by your tax rate.

There is no exemption amount available if you or your associated group of employers has more than $5 million of annual payroll. An employer is not eligible to claim an exemption if associated companies have already claimed the full exemption.

Example (a): An employer has total Ontario remuneration of $1,300,000 before deducting the exemption. They will use a tax rate of 1.95% because the payroll is over $400,000 before the exemption is deducted. The EHT calculation would be:

• $1,300,000 (total Ontario remuneration) minus $1,000,000 (exemption) equals $300,000
• $300,000 (remuneration after deducting exemption) multiplied by 1.95% (tax rate) is $5,850 EHT owing.

Example (b): An employer with $175,000 of Ontario payroll who is not eligible to claim any exemption would use a tax rate of 0.98%. The EHT calculation would be:

• $175,000 (total Ontario remuneration) multiplied by 0.98% (tax rate) is $1,715 EHT owing. 
   

Register for an EHT account

It is your responsibility to register for an EHT account with the Ontario Ministry of Finance if you are an employer who is either:

• not eligible for the exemption
• eligible for the exemption but your payroll exceeds your allowable exemption

Once you register for EHT, we will begin to send you annual returns.

You will be required to register and file a return as an associated employer if any of the following situations apply to you:

• you control, or are controlled, by another employer
• you hold significant influence over another employer, or they hold it over you
• you reported you were associated with another employer on your corporation’s income tax returns
• you opted out of being associated for purposes of the federal small business tax deduction
• you sold or bought another employer during this year
• the total Ontario remuneration for the associated group exceeds the available exemption.

Learn more about associated employers.

Before you register for EHT

You must have the following information for your organization:

• legal name
• trade name
• business address
• mailing address
• telephone and fax numbers
• name of contact person or authorized representative
• payroll start date
• payroll frequency
• federal business number (BN)
• employer type (for example, associated, multiple accounts or public sector employer)

Out-of-province employers

If you are an out-of-province employer, establishing a permanent establishment in Ontario for less than 24 months, it is important that you contact the Ministry. Please call 1-866-668-8297 to discuss requirements for your account registration.

Multiple accounts

An employer may set up separate payrolls for each payroll centre or payroll type and can report them separately by setting up multiple EHT accounts under one BN. A different extension number (e.g., TE0001, TE0002) will be assigned to each account.

A multiple accounts employer must file separate instalments and annual returns for each account. Eligible employers with multiple accounts must allocate the exemption between their accounts.

The tax rate for a multiple account employer is based on the combined Ontario payroll of all the employer’s accounts.

How to register

You can register for an EHT account:

• online
• by calling 1-866-ONT-TAXS (1-866-668-8297)

Pay monthly instalments

Starting in the 2021 tax year, the Employer Health Tax Act requires Ontario businesses with payroll over $1,200,000 to pay monthly instalments. Instalment payments may be made:

• through ONT-TAXS online
• in person at certain ServiceOntario centres
• through online banking or in person at participating Ontario financial institutions (check with your bank)
• by mail to:
  Ministry of Finance
  33 King St W
  PO Box 620  
  Oshawa ON L1H 8E9

If total Ontario remuneration is greater than $1.2 million for 2021 and later

You must pay monthly instalments, and file an annual return on or before March 15^th of the following calendar year.

If total Ontario remuneration is less than $1.2 million for 2021 and later years

You do not have to pay monthly instalments. File your annual return and pay EHT on or before March 15^th of the following calendar year.

Prior to 2021

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

How to calculate the EHT instalment

The requirement for instalment payments is based on the employer’s payroll from the prior year.

If you’re a new employer, in your first or second year of operation, estimate your annual payroll for the current year and use that amount to determine if you will have to make instalment payments. If your estimated annual payroll is over $1.2 million  then instalment payments are required as soon as your payroll exceeds the instalment threshold for the year.

Instalment Example for 2021:

If you have regular monthly payroll of $210,000 per month, you will use up your $1,000,000 exemption after 5 months. That means your payroll costs starting in May 2021 will begin to be subject to EHT. However, you do not need to start making monthly instalment payments until your payroll exceeds the instalment threshold of $1,200,000, which would happen in June. By the end of June, there would be $260,000 in taxable payroll ($210,000 monthly payroll x 6 months - $1,000,000 exemption), which should be multiplied by your EHT tax rate (1.95%). The June monthly instalment would be $5,070, due by July 15^th. To calculate your instalment for each month from July onwards, take your taxable payroll amount ($210,000) and multiply it by your EHT tax rate (1.95%) for a monthly instalment of $4,095 ($210,000 × 1.95%).

Audits

Auditors may carry out audits at your place of business to ensure that you’re in compliance with the EHT Act and Regulations.
