How Ontario Income Tax Works

Ontario uses a progressive tax system, meaning your tax rate increases as your income rises. The province collects income tax through withholding from employment income and through annual tax returns.

The Ontario government uses your taxable income to determine how much tax you owe. Taxable income is calculated by subtracting deductions and credits from your total income.

Taxable Income Formula

Taxable Income = Total Income - Deductions - Tax Credits

Once you have your taxable income, the Ontario government applies the progressive tax rates to calculate your tax liability.

Ontario Tax Brackets

Worked Examples

Example 1: Single Filer with $50,000 Income

For a single filer with $50,000 taxable income:

The first $49,020 is taxed at 5.05%: $49,020 × 0.0505 = $2,499.99
The remaining $980 is taxed at 9.15%: $980 × 0.0915 = $89.52
Total tax owed: $2,499.99 + $89.52 = $2,589.51
Effective tax rate: ($2,589.51 / $50,000) × 100 = 5.18%

Example 2: Married Couple with $100,000 Income

For a married couple filing jointly with $100,000 taxable income:

The first $49,020 is taxed at 5.05%: $49,020 × 0.0505 = $2,499.99
The next $49,020 is taxed at 9.15%: $49,020 × 0.0915 = $4,469.98
The remaining $1,960 is taxed at 11.16%: $1,960 × 0.1116 = $218.53
Total tax owed: $2,499.99 + $4,469.98 + $218.53 = $7,188.50
Effective tax rate: ($7,188.50 / $100,000) × 100 = 7.19%
