Tax refund estimator for Ontario, BC and Alberta

Enter the boxes from your T4 slip and any side income. You'll see your estimated refund or balance owing, and what an RRSP contribution would save. Everything runs in your browser — nothing is sent or stored.

What this includes

Federal and provincial income tax with the basic personal amounts, CPP and EI credits, the Canada employment amount, Ontario's surtax, tax reduction and Health Premium, the BC tax reduction, RRSP and FHSA deductions, and CPP on self-employment income (both halves). Rates are the published figures for each year.

Not included: tuition, medical, donation, disability and family credits, investment income, and other provinces and territories. It's an estimate to help you plan — not tax advice and not a filed return.
