Contribute to an RRSP Now and Claim the Deduction Later?

An eligible RRSP contribution and the deduction claimed for it are related but not identical. You may be able to report a contribution now and deduct it in a later year, subject to your deduction limit and filing requirements.

Adapted from a guide first written for Quebec readers: passages specific to Quebec were removed. Rules in your province may differ.

You can sometimes contribute to an RRSP in one year and claim the deduction in a later year. The contribution still needs to be reported, and an undeducted contribution is not the same thing as unused contribution room. Track both amounts carefully on your CRA records and tax return.

Contribution versus deduction

A contribution puts money into the plan. The deduction is the amount you claim to reduce taxable income on a return. You may deduct an eligible contribution up to the available RRSP deduction limit, but you do not necessarily have to claim every eligible dollar in the same year. Schedule 7 is used to report contributions and certain transfers; the Notice of Assessment shows the limit and unused amounts.

Why someone might wait

If you expect your marginal tax rate to be higher in a later year, delaying a deduction may make that deduction more valuable. But this is not guaranteed: future income, tax rates, benefit calculations, cash-flow needs and investment growth all matter. A refund is not an investment return, and money contributed to an RRSP is generally taxable when later withdrawn.

Safeguards

• Do not contribute beyond your available deduction room; excess contributions can trigger tax.
• Report contributions in the correct tax year, including eligible first-60-day receipts where applicable.
• Keep receipts and reconcile them against Schedule 7 and your CRA account.
• Do not claim a deduction that would exceed the available limit.
