Ontario's Progressive Tax Rates

Ontario uses a progressive tax system where higher income brackets pay higher tax rates. The current tax rates for 2023 are:

Worked Examples

Example 1: Single filer with $50,000 taxable income

Calculation:

$48,535 × 5.05% = $2,449.98
Remaining $1,465 × 9.15% = $134.07
Total tax = $2,449.98 + $134.07 = $2,584.05

Example 2: Married filer with $100,000 taxable income

Calculation:

$48,535 × 5.05% = $2,449.98
$48,534 × 9.15% = $4,433.98
Remaining $5,931 × 11.16% = $662.07
Total tax = $2,449.98 + $4,433.98 + $662.07 = $7,546.03
