RRSP tax savings in Ontario
An RRSP deduction reduces taxable income, so the value of a contribution depends on the tax brackets your income passes through. This calculator uses the 2026 federal and Ontario income tax brackets to estimate the income-tax reduction from an RRSP deduction.
It is designed as a quick planning tool for Ontario residents. Your actual refund can differ because a tax return also includes credits, payroll withholding, Ontario surtax, the Ontario Health Premium, pensions, benefits, and other deductions.
Tip: Check your available RRSP deduction limit in CRA My Account or on your latest Notice of Assessment before contributing.
