Calculate your 2024 Ontario income tax with our free tax calculator. This tool provides an estimate of your provincial tax liability based on your taxable income and deductions. While it's not a substitute for professional tax advice, it helps you understand your tax obligations and plan your finances.

How the 2024 Ontario Tax Calculator Works

The Ontario tax calculator uses the 2024 provincial tax rates and brackets to estimate your tax liability. Here's how the calculation works:

Tax Calculation Formula

Ontario tax = (Taxable Income × Tax Rate) - Deductions

Where Tax Rate is determined by your taxable income bracket.

The calculator applies the progressive tax rates shown in the table below. Each dollar of income in a particular bracket is taxed at that rate, plus the taxes due on the income in all lower brackets.

Important Notes

This calculator provides an estimate based on the current tax laws. Actual tax liability may vary based on your specific circumstances, deductions, and credits. Always consult a tax professional for personalized advice.

2024 Ontario Tax Brackets

The 2024 Ontario tax rates are progressive, meaning higher incomes are taxed at higher rates. Here are the tax brackets for Ontario residents:

Taxable Income	Tax Rate
$0 - $45,142	5.05%
$45,142.01 - $90,287	9.15%
$90,287.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
Over $220,000	13.16%

For example, someone earning $100,000 would pay 5.05% on the first $45,142, 9.15% on the next $54,858 ($45,142.01 to $100,000), resulting in a total tax rate of approximately 8.5%.

What to Enter

Worked Examples

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

Example 1: Low Income

If you earn $50,000 and have no deductions:

Taxable income: $50,000
Tax rate: 5.05% (since $50,000 is in the first bracket)
Estimated tax: $50,000 × 5.05% = $2,525

Example 2: Higher Income

If you earn $120,000 and have $10,000 in deductions:

Taxable income: $120,000 - $10,000 = $110,000
Tax calculation:
- $45,142 × 5.05% = $2,264.71
- ($110,000 - $45,142) × 9.15% = $59,755.29 × 9.15% = $5,453.84
- Total tax = $2,264.71 + $5,453.84 = $7,718.55
