How the Calculation Works
The calculator uses the following formula to determine your Ontario income tax:
Ontario Tax = Sum of (Taxable Income × Rate for Each Bracket)
Where each bracket's rate is applied to the portion of income within that bracket.
The calculator also accounts for federal taxes using the current federal tax brackets. The total tax liability is the sum of provincial and federal taxes.
Worked Example
Let's calculate the tax for a single filer with $100,000 taxable income:
- $48,592 × 5.05% = $2,442.14
- ($97,185 - $48,592) × 9.15% = $4,424.98
- ($100,000 - $97,185) × 11.16% = $262.89
- Total Ontario Tax = $2,442.14 + $4,424.98 + $262.89 = $7,130.01
Adding federal taxes would increase the total tax liability.
