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

You must pay EHT if you have 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 (for example, they work from home) but are paid from or through your Ontario permanent establishment

If your Ontario payroll exceeds your allowable exemption amount, you will have to pay EHT .

You do not have to pay EHT , if you are an eligible employer, as defined under the EHT Act, who has annual payroll below your exemption amount.  

EHT tax exemption

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.

For 2019, Ontario provided EHT relief for small eligible employers through a tax exemption on the first $490,000 of total Ontario payroll each year. For 2014 – 2018, the tax exemption 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
• your board of directors does not include any municipal representatives

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 EHT tax exemption on the first $1,000,000 and pay EHT on the remaining $800,000 of your payroll for the year.

Tax rates and how to calculate EHT

Rates

Calculate your EHT

Your EHT is calculated by multiplying your Ontario payroll for the year – after deducting your tax exemption – by your tax rate. The tax rate you use is based on the level of your Ontario payroll before you have deducted any tax exemption.  There is no tax exemption amount available if you or your associated group of employers has more than $5 million of annual payroll.

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.

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 tax exemption
• eligible for the tax exemption but your payroll exceeds your allowable exemption

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

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:

• online
• in-person by calling 1-866-ONT-TAXS (1-866-668-8297) to make an appointment with a Ministry of Finance representative

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

• through ONT-TAXS online https://www.fin.gov.on.ca/en/services/onttaxs/index.html
• in person at certain ServiceOntario centres
• 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 15th 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 15th of the following calendar year.

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 ($600,000 for 2020 and prior years) 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 15th. 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.

Interest rates may change every 3 months, at the beginning of January, April, July and October.

Understanding your Monthly Account Summary/Notice of Assessment

In the Year - to - Date Summary section, payments are displayed in the Credit/Payment Applied column.

If your payment is greater than the Instalment Amount

The amount displayed in the Credit/Payment Applied column (A) will never exceed the Instalment Amount. If the payment amount is greater than the Instalment Amount, the credit will be displayed in the Balance column (B) of the Year-to-Date Totals. The total payment is displayed at the top of the Account Summary/Notice of Assessment (C). The credit will also be noted on line 3 of the Employer Health Tax Instalment Statement (D).

Example 1

September 2011 Instalment Amount is $1,365.00 with a $1,565.00 payment. The October Account Summary/Notice of Assessment will reflect this as follows:

If your payment is less than the Instalment Amount

If the payment amount is less than the Instalment Amount, the total amount paid will be displayed in the Credit/Payment Applied column (A) and the debit balance reflected in the Balance column of the Year - to - Date Summary (B). This debit will also be displayed in the Balance column of the Year - to - Date Totals (C) and the total payment reflected at the top of the Account Summary/Notice Assessment (D). The debit will also be noted on line 3 of the Employer Health Tax Instalment Statement (E).

Example 2

September 2011 Instalment Amount is $1,365.00 with a payment of $1,165.00 and there is not enough credit on account to cover. The October Account Summary/Notice of Assessment will reflect this as follows:

If your payment is less than the Instalment Amount but there is a credit on your account

If the payment amount is less than the Installment Amount and there is a credit on the account as shown in the previous months statement (see Example 1), this credit will be added to the payment and displayed as one total in the Credit/Payment Applied column (A). The total payment amount will be displayed at the top of the Account Summary/Notice of Assessment (B).

Example 3

October 2011 Instalment Amount is $1,560.00 with a payment of $1,360.00 and there is enough credit on the account to cover the $200.00 difference. The November Account Summary/Notice of Assessment will reflect this as follows:
