RRSP tax refund calculator

An RRSP contribution is deducted from your income, so it saves tax at your top marginal rates. You get the saving as a refund when you file, unless your employer reduces payroll tax at source.

Within your deduction limit on your notice of assessment: 18% of last year’s earned income, up to the yearly maximum.

Your answer

Tax saved$2,965.00
