Ontario 2020 Income Tax Calculator

Calculate your Ontario income tax for the 2020 tax year using this official calculator. This tool provides an estimate of your tax liability based on your income, deductions, and credits. For exact figures, consult a tax professional or use official government resources.

How the Ontario 2020 Tax Calculator Works

The Ontario 2020 income tax calculator estimates your tax liability using the progressive tax rates for the 2020 tax year. The calculation follows these steps:

Calculate your taxable income by subtracting eligible deductions from your total income.
Apply the Ontario tax brackets to your taxable income.
Subtract any eligible tax credits to determine your final tax liability.

Formula

Tax Liability = (Taxable Income × Tax Rate) - Tax Credits

Taxable Income = Total Income - Deductions

The Ontario government uses a progressive tax system, meaning higher income brackets are taxed at higher rates. The 2020 tax rates were:

15% on the first $44,753 of taxable income
28.5% on the next $44,753
33% on the next $50,251
39.5% on taxable income over $139,757

Worked Example

Let's calculate the tax for a single Ontario resident with $80,000 income, $5,000 in RRSP contributions, and $1,000 in tax credits.

Taxable Income = $80,000 - $5,000 = $75,000
First $44,753 at 15% = $6,713
Next $30,253 at 28.5% = $8,652
Total Tax Before Credits = $6,713 + $8,652 = $15,365
Final Tax Liability = $15,365 - $1,000 = $14,365

Example Result

Estimated Tax Liability: $14,365
