In 2020, Ontario had the following progressive tax rates:

Taxable Income	Tax Rate
$0 - $44,703	5.05%
$44,704 - $89,407	9.15%
$89,408 - $150,000	11.16%

Over $220,000	13.16%

These rates apply to all Ontario residents, regardless of their filing status. The calculator uses these exact rates to compute your tax liability.

Calculation Method

The calculator uses the following method to determine your tax liability:

Determine your taxable income by subtracting any deductions or exemptions from your total income.
Apply the Ontario tax rates to each portion of your taxable income that falls into different brackets.
Sum the taxes from each bracket to get your total tax payable.

Tax Calculation Formula

For a given taxable income (I), the tax (T) is calculated as:

T = (I₁ × 0.0505) + (I₂ × 0.0915) + (I₃ × 0.1116) + (I₄ × 0.1216) + (I₅ × 0.1316)

Where:

I₁ = Income in the first bracket ($0 - $44,703)
I₂ = Income in the second bracket ($44,704 - $89,407)
I₃ = Income in the third bracket ($89,408 - $150,000)
I₄ = Income in the fourth bracket ($150,001 - $220,000)
I₅ = Income above $220,000

The calculator handles all these calculations automatically once you enter your income and filing status.

Worked Example

Let's calculate the tax for a single Ontario resident with a taxable income of $120,000 in 2020.

First $44,703: $44,703 × 5.05% = $2,261.91
Next $44,704 to $89,407: $44,704 × 9.15% = $4,060.56
Next $30,593 to $120,000: $30,593 × 11.16% = $3,414.36
Total tax: $2,261.91 + $4,060.56 + $3,414.36 = $9,736.83

So, a taxable income of $120,000 would result in approximately $9,736.83 in Ontario income tax for 2020.

Note: This is a simplified example. Actual tax calculations may include additional deductions, credits, and adjustments.
