Canadian Income Tax Comparison Calculator

What this calculator compares

Compare estimated personal income tax across Canada’s 13 provinces and territories using the same annual taxable income. The results show estimated tax, average tax rates and marginal rates for different income types. This is an income-tax comparison, not a take-home-pay calculation.

How to use the calculator

Enter annual taxable income, not gross salary. Select Compare across Canada, then select a jurisdiction to inspect its tax breakdown.

On a small screen, the mini dropdown in the table heading switches between average and marginal rates. The separate income-type selector changes the second table. Neither selector changes the taxable income or estimated tax.

How the comparison is calculated

Each jurisdiction is calculated separately using the stated 2026 tax model. The comparison assumes an individual under 65, without spouse, dependant or pension-income amounts claimed. Where net income is required, it is assumed to equal taxable income; that is a modelling convention, not a tax-law identity.

The average rate is estimated tax divided by taxable income when that income is greater than zero. Each marginal rate measures the tax change from adding $100 of one income type to the same starting income. The four additions are tested separately, not accumulated.

How to interpret the results and limits

The headline range compares jurisdictions; it is not a confidence interval around one person’s tax bill. A negative dividend rate can mean a lower estimated tax liability, not necessarily a refund. At zero taxable income, the average rate is not applicable.

The model does not reproduce every credit, deduction, benefit interaction or filing circumstance. It excludes payroll deductions and AMT, and it does not compare living costs or determine where someone should live. The result disclosure identifies the calculation basis; jurisdiction details explain included adjustments.
