How Much Tax Does an RRSP Contribution Save?

An RRSP contribution reduces your taxable income by the exact amount you contribute. The tax savings depend on your marginal tax rate (federal + provincial combined):

Province	Income $60K — Marginal Rate	Tax Saved on $10K RRSP
Ontario	~43.41%	~$4,341
British Columbia	~40.70%	~$4,070
Alberta	~30.50%	~$3,050
Quebec	~45.71%	~$4,571
Nova Scotia	~46.50%	~$4,650

How to Find Your RRSP Contribution Room

Your available RRSP room (deduction limit) is shown on your most recent Notice of Assessment from the CRA. You can also find it by logging into CRA My Account online. Unused room carries forward indefinitely — if you didn't contribute in prior years, that room is still available.

RRSP Contribution Deadline 2025

The RRSP deadline for contributions claimable on your 2024 return is March 3, 2025 — which is 60 days after December 31, 2024. This is a hard deadline. Contributions made on March 4 or later cannot be claimed on your 2024 return; they apply to 2025 instead. Make your contribution well in advance — bank processing can take 1–3 business days.

Should You Contribute to RRSP or TFSA?

The RRSP vs. TFSA decision depends primarily on your income now vs. expected income in retirement:

• RRSP is better when your current marginal tax rate is higher than your expected retirement rate — contributions save more tax now than you'll pay later on withdrawals
• TFSA is better when your income is low now or you expect similar/higher income in retirement — no deduction going in, but all growth and withdrawals are completely tax-free
• Do both if you have room and cash flow to spare — max RRSP first if you're a higher earner, TFSA first if you're lower income

Spousal RRSP — Income Splitting in Retirement

A spousal RRSP lets you contribute to your spouse's or common-law partner's RRSP. You get the tax deduction now (using your own contribution room), but in retirement your spouse withdraws the funds at their (potentially lower) tax rate. This is a powerful income-splitting strategy for couples where one partner earns significantly more. Note: if your spouse withdraws within 3 years of your contribution, the income is attributed back to you.

RRSP Home Buyers' Plan (HBP)

First-time home buyers can withdraw up to $35,000 from their RRSP tax-free under the Home Buyers' Plan. The withdrawal must be repaid over 15 years. If you don't repay the minimum annual amount, it is added to your income for that year. The HBP can be combined with the First Home Savings Account (FHSA) for an even larger down payment tax advantage.

RRSP Lifelong Learning Plan (LLP)

You can withdraw up to $100 per year (max $20,000 total) from your RRSP under the Lifelong Learning Plan to finance full-time education or training for yourself or your spouse. The withdrawals are not taxed if repaid within 10 years (2 years after the last year of study). This is a useful bridge for career changers or those returning to school.
