RRSP Contribution Limit and Deadline for 2026

The two numbers that decide your room

Your RRSP contribution room for a year comes down to two figures, and you take whichever is smaller:

• 18 percent of your earned income from the previous year, and
• the annual dollar limit, which is $33,810 for 2026.

If 18 percent of last year's earned income is below the dollar cap, your room is that 18 percent figure. If it is above the cap, your room is limited to $33,810. The cap is what stops very high earners from sheltering an unlimited amount.

The exact figure for your own situation is printed on your latest CRA notice of assessment and shown in your CRA My Account. The rules below explain how that number is built.

The 18 percent rule and the dollar cap

Earned income for RRSP purposes is mostly employment income, net self-employment income, and a few other sources such as net rental income. Investment income and capital gains do not count toward it.

So someone with $80,000 of earned income in the prior year generates 18 percent of that, which is $14,400 of new room, comfortably under the $33,810 cap. Someone with $250,000 of earned income would calculate 18 percent as $45,000, but their new room is capped at $33,810 instead.

The dollar cap is indexed and rises most years, which is why the 2026 figure differs from earlier years.

Unused room carries forward

You do not lose room you do not use. Any contribution room you do not use in a given year carries forward indefinitely and adds to your room in future years.

This is why many people have far more room available than a single year's calculation would suggest. If you contributed little in your earlier working years, that unused room is still sitting there, available whenever you have the cash to use it. It is also why a large one-time contribution, for example after a bonus or an inheritance, is often perfectly within the rules even though it exceeds a single year's 18 percent figure.

The contribution deadline

RRSP contributions work on a slightly unusual calendar. You can apply a contribution to a given tax year if you make it during that year or within the first 60 days of the following year.

In practice that places the deadline for the 2025 tax year in early March 2026. The cutoff is normally March 1, and when that date lands on a weekend it moves to the next business day. A contribution made in those first 60 days can be deducted on either the prior year's return or a later one, which gives you some flexibility to claim the deduction in the year it saves you the most tax.

Because the deduction reduces taxable income at your marginal rate, the RRSP Tax Refund Calculator is the quickest way to see what a given contribution is worth to you before the deadline.

How a workplace pension affects your room

If you belong to a registered pension plan or a deferred profit sharing plan at work, your RRSP room is reduced by a pension adjustment. The idea is that you are already building retirement savings through the workplace plan, so your separate RRSP room is trimmed to keep total tax-sheltered saving roughly fair across people with and without a pension.

The pension adjustment appears on your T4 and is already factored into the room shown on your notice of assessment. If you have a generous defined-benefit pension, do not be surprised to see modest RRSP room even on a good salary.

Over-contributions and the penalty

There is a lifetime buffer of $2,000. You can be over your contribution limit by up to that amount without a penalty, although the excess is not deductible.

Go beyond the $2,000 cushion and the CRA charges a penalty of 1 percent per month on the excess for as long as it stays in the account. That adds up quickly, so it is worth tracking your room rather than guessing. If you do over-contribute, withdrawing the excess promptly limits the penalty.

Frequently asked questions

What is the RRSP dollar limit for 2026? The annual dollar limit is $33,810. Your actual room is the lesser of that figure and 18 percent of your prior-year earned income, plus any unused room carried forward.

When is the RRSP deadline for the 2025 tax year? Within the first 60 days of 2026, which normally means on or around March 1, moving to the next business day if it falls on a weekend.

Does unused RRSP room expire? No. Unused room carries forward indefinitely and is added to your room in later years.

Do capital gains count as earned income for RRSP room? No. RRSP room is based on earned income such as employment and net self-employment income. Capital gains and investment income do not generate room.

How much will a contribution save me in tax? A contribution reduces your taxable income at your marginal rate. Enter your income, province, and contribution amount in the RRSP Tax Refund Calculator to see the estimated refund.
