How Marginal Tax Rates Work in Ontario

Marginal tax rates refer to the rate at which your next dollar of income is taxed. In Ontario, your effective tax rate depends on both federal and provincial tax brackets.

The Ontario government uses a progressive tax system, meaning higher income brackets are taxed at higher rates. The current tax rates (as of 2023) are:

Federal Tax Brackets

Income Range	Tax Rate
$0 - $53,359	15%
$53,359 - $106,717	20.5%
$106,717 - $165,430	26%
$165,430 - $235,675	29%
$235,675+	33%

Ontario Provincial Tax Brackets

Income Range	Tax Rate
$0 - $49,231	5.05%
$49,231 - $98,462	9.15%
$98,462 - $150,000	11.16%
$150,000 - $220,000	12.16%
$220,000+	13.16%

The combined federal and provincial tax rates create a more complex marginal tax structure. For example, your first $53,359 is taxed at 15% federally and 5.05% provincially, totaling 20.05% for that portion of income.

Federal vs. Provincial Tax Rates

The federal government and Ontario province each have their own tax brackets. The combined effect means your marginal tax rate changes at different income levels than either system alone.

Effective Marginal Tax Rate = Federal Marginal Rate + Provincial Marginal Rate

For example, if you earn $60,000:

The first $53,359 is taxed at 15% federal + 5.05% provincial = 20.05%
The remaining $6,641 is taxed at 20.5% federal + 9.15% provincial = 29.65%
Your effective marginal tax rate for the $6,641 is 29.65%

This means your next dollar earned is taxed at 29.65%, not the 20.5% federal rate alone.

Frequently Asked Questions

What is the difference between marginal and average tax rates?

Marginal tax rates show how your next dollar is taxed, while average tax rates show the total tax paid divided by total income. Marginal rates are higher for higher income brackets because you're paying more on your higher-earning years.

How do tax credits affect my marginal rate?

Tax credits reduce your tax liability dollar-for-dollar, effectively lowering your marginal rate. For example, if you have a $2,000 tax credit and your marginal rate is 25%, you save $500 in taxes.

Are there any deductions that can lower my taxable income?

Yes, you can claim deductions for eligible expenses like RRSP contributions, medical expenses, and home office costs. These reduce your taxable income, potentially lowering your marginal rate.

How often do tax rates change?

Tax rates are typically updated annually when the federal and provincial budgets are introduced. Major changes are rare but can occur if the government introduces new tax policies.
