How Much Tax Refund Does an RRSP Contribution Give You?

Short answer: There's no fixed refund. An RRSP deduction lowers your taxable income, so the tax saved depends on your marginal tax rate (federal plus provincial) and your other credits. We don't publish provincial rate tables because we haven't verified current ones.
Rough idea (made-up numbers)
Estimated tax effect ≈ deductible contribution × your marginal rate. | Deductible contribution | Marginal rate you enter | Estimated tax reduction | |---|---|---| | $5,000 | 20% | $1,000 | | $5,000 | 30% | $1,500 | | $5,000 | 40% | $2,000 |
These are illustrations. The actual result is on your notice of assessment.
Cautions
- It is a deferral for many people: withdrawals are generally taxable (not covered in detail here).
- You can only deduct contributions up to your limit (see limits).
- Fees and interest on borrowed money are not deductible (CRA).
- Contributions over the limit by more than $2,000 trigger a 1% monthly tax.
How to find your marginal rate
Use your tax software or CRA's information, or ask a tax professional. We are not providing a rate for you.
