RRSP Contribution Deadline: The First 60 Days Rule and Last-Minute Strategies

The First 60 Days Rule: How It Works

The Registered Retirement Savings Plan (RRSP) operates on a contribution year that extends beyond the calendar year. According to the Canada Revenue Agency (CRA), you can contribute to your RRSP within 60 days after the end of the calendar year and apply that contribution to the previous tax year. In practice, this means amounts deposited in January and February are deductible on your prior-year tax return.

For example, a contribution made on January 15, 2026 can reduce your 2025 taxable income. The exact deadline falls around March 1 to 3 depending on the year, since 60 days after December 31 shifts slightly in leap years. Always verify the exact date on canada.ca, as the CRA confirms it each year.

To find out how much room you have, check your prior-year Notice of Assessment or log in to My Account on the CRA website. You can also use our RRSP calculator to estimate the impact on your tax refund.

Why So Many People Wait Until the Last Minute

Most people contribute in January and February for two main reasons: they wait until they have a clear picture of their annual income to maximize the deduction, and they simply procrastinate on what feels non-urgent. Many financial institutions run heavy advertising campaigns during this window, which amplifies the sense of urgency.

It helps to distinguish two separate deadlines: the RRSP contribution deadline (early March) and the tax filing deadline (April 30 for most individuals). Even if you contribute before the early-March deadline, you are not required to claim the deduction on your prior-year return — you can defer it.

The RRSP Loan: A Strategy to Handle with Care

If you lack the cash but want to maximize your contribution, an RRSP loan lets you borrow from a financial institution, deposit the amount into your RRSP immediately, and then repay the loan using the tax refund you receive. The idea is that the refund covers much — or all — of the loan.

But there are real risks to weigh:

• Interest on an RRSP loan is not tax-deductible, unlike interest on money borrowed for non-registered investment purposes.
• If your marginal tax rate is low, the tax savings may not cover the interest costs.
• Slow repayment extends the interest period and reduces the net benefit of the strategy.
• Variable income earners risk overestimating their refund and ending up with residual debt.

An RRSP loan can make sense for a high-income earner with a stable salary and a significant catch-up contribution to make. For everyone else, run the numbers carefully before committing.

Deferring the Deduction to a Higher-Income Year

Here is a nuance many people overlook: contributing to your RRSP and claiming the RRSP deduction are two separate actions. You can deposit money now — letting it grow tax-sheltered immediately — and choose to claim the deduction on a future return when your marginal tax rate is higher.

This approach is particularly useful if:

• You are early in your career with modest income but expect significant earnings growth in the coming years.
• You received exceptional income this year (a bonus, asset sale) but anticipate an even higher-income year ahead.
• You simply want to start sheltering investment growth now without optimizing the deduction immediately.

The CRA allows this deduction deferral with no time limit. However, the contribution must still fall within your available contribution room to avoid an overcontribution — which is penalized at 1% per month on amounts exceeding $2,000 over your limit.

Unused Room Carries Forward: There Is No Absolute Rush

One of the most reassuring features of the RRSP is that unused contribution room accumulates from year to year with no expiry. If you cannot contribute this year, you do not lose that room — it simply rolls over to future years.

Each year, new contribution room accrues at 18% of your prior year's earned income, up to the annual dollar limit set by the CRA (check the current limit on canada.ca). If you have accumulated unused room over several years, your total available contribution capacity may be substantial.

This means someone who was unable to contribute for three years has not forfeited anything. They simply have more flexibility in future years — for instance, in a year of exceptionally high income where the deduction would deliver an even greater tax benefit.

In summary, the early-March RRSP deadline is real and matters if you want to deduct a contribution on your prior-year return. But it should not push you into a hasty decision. Always confirm the exact date on canada.ca, assess your tax situation carefully, and consult a qualified tax advisor when in doubt.
