Formula Explained

The calculator uses the following formula to convert post-tax income to pre-tax:

Pre-tax Income = Post-tax Income / (1 - Tax Rate)

Where:

Post-tax Income - Your income after taxes are deducted
Tax Rate - The applicable tax rate based on your income bracket

Ontario's tax rates are progressive, meaning higher income brackets have higher tax rates. The calculator uses the following tax brackets for 2023:

Income Bracket	Tax Rate
$0 - $49,020	5.05%
$49,020.01 - $98,040	9.15%
$98,040.01 - $150,000	11.16%
$150,000.01 - $220,000	12.16%
$220,000.01+	13.16%

Note: These rates are approximate and may change. For exact calculations, refer to the Canada Revenue Agency's official tax tables.

Worked Examples

Example 1: Single person in $50,000 income bracket

If you earn $40,000 after taxes:

Pre-tax Income = $40,000 / (1 - 0.0505) = $42,083.33

This means your pre-tax income would be approximately $42,083.33 to result in $40,000 after taxes.

Example 2: Single person in $100,000 income bracket

If you earn $80,000 after taxes:

Pre-tax Income = $80,000 / (1 - 0.0915) = $88,235.30

This means your pre-tax income would be approximately $88,235.30 to result in $80,000 after taxes.
