Income Tax Calculator Ontario 2024

How the Ontario Income Tax Calculator Works

The Ontario income tax calculator estimates your tax liability by applying Ontario's progressive tax rates to your taxable income. The calculation process involves several key steps:

1. Determine your taxable income by subtracting eligible deductions from your total income
2. Apply Ontario's tax brackets to calculate provincial tax
3. Calculate federal tax using Canada's tax brackets
4. Add provincial and federal taxes to get total tax liability
5. Subtract any eligible tax credits

This calculator uses the official 2024 tax rates and brackets provided by the Government of Ontario and Canada Revenue Agency. The results are estimates and may not reflect your actual tax liability.

2. Select your filing status (Single, Married, or Other)
3. Enter any eligible deductions in the "Deductions" field
4. Enter any tax credits in the "Credits" field
5. Click "Calculate" to see your estimated tax liability

Worked Examples

Let's look at two examples to understand how the calculator works:

Example 1: Single filer with $50,000 income

Total Income: $50,000

Deductions: $5,000 (RRSP contributions)

Taxable Income: $45,000

Provincial Tax: $45,000 × 5.05% = $2,272.50

Federal Tax: $45,000 × 15% = $6,750

Total Tax Before Credits: $9,022.50

Credits: $1,000 (Ontario Child Benefit)

Estimated Tax Liability: $8,022.50

Example 2: Married filers with $120,000 combined income

Total Income: $120,000

Deductions: $10,000 (RRSP contributions)

Taxable Income: $110,000

Provincial Tax: $110,000 × 9.15% = $10,065

Federal Tax: $110,000 × 20.5% = $22,550

Total Tax Before Credits: $32,615

Credits: $2,500 (Ontario Child Benefit)

Estimated Tax Liability: $29,615
