Tax refund estimator
The estimator starts with employment income, subtracts the entered RRSP deduction, applies year-specific federal and supported provincial or territorial brackets, then subtracts the basic personal and Canada employment credits. Eligible donation credits are applied through the shared donation engine. Ontario surtax and Health Premium, B.C.’s low-income tax reduction, Manitoba’s income-tested basic amount, and Yukon’s income-tested basic amount are included.
It compares estimated income tax with tax already deducted. It does not model Quebec, CPP/QPP or EI/QPIP reconciliation, other income types, spouse or dependant claims, tuition, disability or medical credits, dividends, capital gains, self-employment, non-residency, or many province-specific credits and reductions.
RRSP tax savings
The income-tax engine runs before and after the proposed deduction. The difference is estimated tax savings, not a guaranteed refund increase. The tool does not calculate available contribution room and caps the modeled deduction at entered employment income.
Donation tax credit
The calculator applies the supported federal and provincial or territorial non-refundable donation-credit rates, including first-$200 and above-$200 tiers and supported highest-income tiers. It assumes an eligible gift and official receipt, and applies the general claim limit of 75% of entered net income. It does not optimize carry-forwards or model ecological, cultural, estate, or other special gifts.
GST / HST
Add-tax mode applies the selected jurisdiction’s supported rate and rounds to cents. Reverse mode divides the tax-included total by one plus the combined rate. Results assume an ordinary fully taxable supply; exemptions, zero-rated supplies, rebates, place-of-supply rules, and special product taxes are outside scope.
Mortgage payments
The entered nominal annual rate is converted from Canadian semi-annual compounding to an equivalent payment-period rate. Level-payment formulas estimate principal and interest; accelerated schedules use one-half or one-quarter of the monthly payment. Results do not represent approval or affordability and exclude mortgage insurance, property tax, fees, renewals, and future rate changes.
Tax years
2025 is presented as a tax-return year. 2026 is an estimate based on currently published rates and rules as verified August 21, 2026; filing forms and personal administrative outcomes may differ.
