Tax Calculation Formula

The calculator uses the following formula to estimate your Ontario taxes:

Net Pay = Gross Income - (Federal Tax + Provincial Tax + CPP + EI)

The tax rates for Ontario residents are based on the current tax brackets provided by the Canada Revenue Agency (CRA) and the Ontario government.

Federal Tax Calculation

The federal tax is calculated using progressive tax brackets. For example:

Federal Tax = Sum of (Taxable Income × Rate for each bracket)

Provincial Tax Calculation

Ontario uses a flat tax rate for the first $44,773 of taxable income, then progressive rates for higher incomes.

Provincial Tax = Sum of (Taxable Income × Rate for each bracket)

CPP and EI Calculation

CPP and EI are calculated as percentages of your earnings, with maximum contribution limits.

CPP = Earnings × CPP Rate (up to maximum)

EI = Earnings × EI Rate (up to maximum)

Worked Example

Let's calculate taxes for a single Ontario resident with a gross income of $60,000.

Step 1: Federal Tax Calculation

Using the 2023 federal tax brackets:

$0 - $53,359: 15% tax rate
$53,359 - $106,717: 20.5% tax rate
$106,717 - $220,000: 26% tax rate

Federal Tax = ($53,359 × 0.15) + (($60,000 - $53,359) × 0.205)

Federal Tax = $8,003.85 + $1,323.05 = $9,326.90

Step 2: Provincial Tax Calculation

Ontario tax brackets for 2023:

$0 - $44,773: 5.05% tax rate
$44,773 - $89,543: 9.15% tax rate
$89,543 - $150,000: 11.16% tax rate
$150,000 - $220,000: 12.16% tax rate

Provincial Tax = ($44,773 × 0.0505) + (($60,000 - $44,773) × 0.0915)

Provincial Tax = $2,269.90 + $1,275.05 = $3,544.95

Step 3: CPP and EI Calculation

Using 2023 rates:

CPP Rate: 5.95% (maximum $3,480)
EI Rate: 1.66% (maximum $910)

CPP = $60,000 × 0.0595 = $3,570.00

EI = $60,000 × 0.0166 = $996.00

Final Calculation

Total Deductions = $9,326.90 (Federal) + $3,544.95 (Provincial) + $3,570.00 (CPP) + $996.00 (EI)

Total Deductions = $17,437.85

Net Pay = $60,000 - $17,437.85 = $42,562.15
