Your RRSP refund isn't a bonus

November 7, 20264 min read

Every spring, many Canadians get an RRSP tax refund and treat it like a gift. It isn't. It's the government deferring tax until you withdraw the money, usually in retirement.

How the refund works

Contributions to an RRSP reduce your taxable income. If your marginal tax rate is 30% and you contribute $10,000, your tax bill falls by about $3,000. That's the refund.

But every dollar that comes out of the RRSP later is taxed as income. The $3,000 isn't extra money; it's tax you'll pay later instead of now.

When the refund really pays off

  • If you reinvest it. Put the $3,000 into your TFSA or back into the RRSP, and it compounds alongside your contribution. Spend it, and the RRSP's advantage shrinks a lot.
  • If your tax rate is lower in retirement. Deducting at 30% and withdrawing at 20% is a genuine gain. Deducting at 20% and withdrawing at 30% loses money compared with a TFSA.

A simple comparison

You earn $10,000 before tax to invest, at a 30% tax rate now and later. RRSP: invest the full $10,000; it doubles to $20,000; you withdraw and pay 30%, leaving $14,000. TFSA: pay tax first, invest $7,000; it doubles to $14,000, withdrawn tax-free. Same result. The RRSP only comes out ahead if your rate falls in retirement, and it only matches the TFSA if you invest the whole pre-tax amount, refund included.

The habit

Decide before the refund arrives where it's going. The simplest rule: refund in, refund invested. Or ask your employer to reduce tax withheld at source (CRA form T1213) so the refund effectively lands in each paycheque, and invest it there.
