Canadian tax math is simple in theory and a mess in practice. Federal brackets stack on top of provincial brackets, the basic personal amount phases down at high incomes, capital gains have a new 2/3 inclusion rate over $250,000, and the GST/HST credit is being folded into the new CGEB in July 2026. Our tax calculators handle every one of those moving pieces using the 2026 CRA brackets and the latest provincial tables for all 10 provinces and 3 territories.

If you only want one number — what will I owe, or what will my refund be — start with the Income Tax Calculator. It runs a full T1 estimate including federal + provincial tax, the basic personal amount, CPP and EI, and any RRSP deduction you enter. If you're trying to decide whether the next $1,000 of income is worth chasing, use the Marginal Tax Calculator instead — it shows your true marginal rate including provincial surtaxes.

For investors, the Capital Gains Calculator applies the new 2/3 inclusion rate correctly, including the $250,000 annual threshold below which the 50% rate still applies. For everyone else, the GST/HST Calculator handles the rate jungle (5% in AB, 15% HST in NS/NB/NL/PE, etc.) and the GST/HST Credit Estimator predicts your quarterly cheque.
