These rates are subject to change each year. The calculator automatically uses the most current rates available.

How Ontario Income Tax Works

Ontario's income tax system is progressive, meaning higher incomes are taxed at higher rates. The tax is calculated by applying each tax rate to the portion of income that falls within that bracket.

The Ontario government uses this progressive system to ensure that higher earners contribute a larger share of their income through higher tax rates.

Worked Examples

Example 1: $50,000 Income

For a taxable income of $50,000:

• $49,020 × 5.05% = $2,451.01
• ($50,000 - $49,020) × 9.15% = $88.90
• Total tax = $2,451.01 + $88.90 = $2,539.91
• Net income = $50,000 - $2,539.91 = $47,460.09
• Effective tax rate = ($2,539.91 / $50,000) × 100 = 5.08%

Example 2: $100,000 Income

For a taxable income of $100,000:

• $49,020 × 5.05% = $2,451.01
• ($98,040 - $49,020) × 9.15% = $4,322.09
• ($100,000 - $98,040) × 11.16% = $180.00
• Total tax = $2,451.01 + $4,322.09 + $180.00 = $7,053.10
• Net income = $100,000 - $7,053.10 = $92,946.90
• Effective tax rate = ($7,053.10 / $100,000) × 100 = 7.05%
