Calculate Your Tax Rate Ontario

Calculating your Ontario tax rate helps you understand how much tax you owe on your income. This calculator uses the current provincial tax brackets to provide an estimate of your tax liability. Whether you're an Ontario resident or planning to move there, knowing your tax rate is essential for financial planning.

How Ontario Tax Rates Work

Ontario uses a progressive tax system, meaning your tax rate increases as your income rises. The provincial government sets tax brackets that determine how much tax you pay on different portions of your income.

Note: This calculator uses the 2023 tax rates. Check the Ontario Revenue Agency (ORA) website for the most current rates if you're calculating taxes for a future year.

Key Tax Concepts

Progressive taxation: Higher income earners pay a higher percentage of their income in taxes.
Tax brackets: Income ranges that have different tax rates.
Marginal tax rate: The tax rate applied to the last dollar of your income.

Federal vs. Provincial Taxes

In Ontario, you pay both federal and provincial taxes. The calculator focuses on provincial taxes, but it's important to note that your total tax liability includes both levels of government.

Ontario Tax Brackets

The current Ontario tax brackets for 2023 are as follows:

Taxable Income	Tax Rate
$0 - $44,703	5.05%
$44,704 - $89,407	9.15%
$89,408 - $138,585	11.16%
$138,586 - $206,350	12.16%
$206,351+	13.16%

Formula: Ontario tax = (Taxable income × Tax rate) - (Tax credits + Deductions)

The taxable income is your total income minus any eligible deductions. The tax credits reduce your tax liability dollar-for-dollar.
