Ontario Tax Formula

The Ontario provincial tax is calculated using progressive tax brackets. The formula is:

Ontario Tax = Sum of (Taxable Income × Tax Rate for each Bracket)

Where:

Taxable Income is your total income minus deductions and credits.
Tax Rate is the percentage applied to each bracket of income.

For example, if your taxable income is $50,000 and you're single, the calculation would be:

Ontario Tax = ($44,701 × 5.05%) + ($5,299 × 9.15%) + ($4,000 × 11.16%) + ($5,000 × 12.16%) + ($20,000 × 13.16%)

Example Calculation

Let's calculate the Ontario tax for a single filer with $50,000 in taxable income.

First $44,700 at 5.05%: $44,700 × 0.0505 = $2,261.65
Next $5,299 at 9.15%: $5,299 × 0.0915 = $485.25
Next $4,000 at 11.16%: $4,000 × 0.1116 = $446.40
Next $5,000 at 12.16%: $5,000 × 0.1216 = $608.00
Remaining $20,000 at 13.16%: $20,000 × 0.1316 = $2,632.00

Total Ontario Tax: $2,261.65 + $485.25 + $446.40 + $608.00 + $2,632.00 = $6,433.30
