Ontario Health Premiums are additional fees collected from taxpayers to fund provincial healthcare services. The amount you pay depends on your taxable income for the year. This guide explains how to calculate your 2025 Ontario Health Premium based on your income, including the tax brackets and the exact formula used.

How to Calculate Ontario Health Premiums

The Ontario Health Premium is a percentage of your taxable income, calculated based on specific income brackets. The exact rate depends on your income level for the year. Here's how the calculation works:

Note: Health Premium rates are subject to change each year. The 2025 rates are based on current projections and may be adjusted before the final tax year begins.

Key Steps in the Calculation

Determine your taxable income for the year
Identify which income bracket your taxable income falls into
Apply the corresponding Health Premium rate to your income
Round the result to the nearest dollar

The Health Premium is added to your Ontario tax liability and is not refundable. It's important to understand how this affects your overall tax burden, especially if you're in a higher income bracket.

2025 Taxable Income Brackets

The Ontario Health Premium is calculated using the following taxable income brackets for 2025:

Income Bracket	Health Premium Rate
$0 - $45,282	1.6%
$45,283 - $90,567	2.5%
$90,568 - $150,000	3.3%
$150,001 - $220,000	4.0%
Over $220,000	5.0%

These brackets are based on projected tax rates for 2025. The actual rates may differ slightly when the final tax tables are released by the Ontario government.

Health Premium Calculation Formula

The exact formula for calculating the Ontario Health Premium is:

Health Premium = Taxable Income × Premium Rate

Where the Premium Rate is determined by your taxable income bracket as shown in the table above. The calculation is straightforward but important to understand, especially if you're in a higher income bracket where the premium rate increases significantly.

For example, if your taxable income is $120,000, you would fall into the $90,568 - $150,000 bracket with a 3.3% premium rate. The calculation would be:

Health Premium = $120,000 × 3.3% = $3,960

Example Calculation

Let's walk through a complete example to illustrate how the calculation works.

Scenario: Single Filer with $110,000 Taxable Income

Determine taxable income: $110,000
Identify income bracket: $90,568 - $150,000 (3.3% rate)
Calculate premium: $110,000 × 3.3% = $3,630
Round to nearest dollar: $3,630

In this case, the Ontario Health Premium would be $3,630, which would be added to your total tax liability. This represents an additional 3.3% of your taxable income in this bracket.

Remember: The Health Premium is not refundable, even if you have a tax refund. It's important to budget for this additional expense when preparing your tax return.
