How RRSP contribution room works in Canada

A Registered Retirement Savings Plan (RRSP) is a tax-advantaged account that lets Canadians save for retirement. Each year, you generally generate new RRSP room equal to 18% of your prior-year earned income, up to an annual dollar limit set by the CRA. Your total RRSP deduction limit equals this new room plus any unused room from prior years, reduced by pension adjustments if you are a member of a pension plan.

2026 RRSP contribution limit

The 2026 RRSP dollar limit is $33,810.00. This caps the new RRSP room you can generate from 2025 earned income, but unused room from previous years can make your total deduction limit higher.

How the 18% rule works

For the 2026 tax year, your new RRSP room is 18% of your 2025 earned income, up to the annual limit of $33,810.00. Earned income generally includes employment earnings, self-employment net income, and certain other income, but excludes investment income and certain passive income. If you earned $33,810.00 or more in 2025, your new room reaches the full annual limit.

Unused RRSP room and carry-forward

If you contribute less than your deduction limit in a year, the unused amount carries forward indefinitely. Your total RRSP deduction limit is the sum of all unused room from previous years plus new room generated in the current year, minus pension adjustments. You can find your unused room on your CRA Notice of Assessment.

How pension adjustments affect RRSP room

A Pension Adjustment (PA) represents the value of pension benefits earned in a registered pension plan. It reduces your RRSP room so that pension plan members and RRSP savers receive comparable tax assistance. A Pension Adjustment Reversal (PAR) can restore room if you leave a pension plan early, while a Past Service Pension Adjustment (PSPA) reduces room when past pension benefits are upgraded.

RRSP contributions vs RRSP deductions

Contributing to an RRSP and claiming an RRSP deduction are separate steps. You can contribute in one year and deduct in a future year if that is more advantageous. Unused contributions remain available for future deduction. This calculator estimates your deduction limit and remaining room, not your optimal deduction timing.

What happens if you over-contribute

Excess RRSP contributions above your deduction limit may be subject to a 1% per month tax on the highest excess amount in each month. The CRA provides a lifetime $2,000 excess-contribution buffer before this tax typically applies. The actual tax depends on monthly balances and timing, which this calculator does not track.

The $2,000 excess-contribution buffer explained

The CRA’s $2,000 lifetime excess-contribution buffer allows you to contribute up to $2,000 above your deduction limit without triggering the 1% per month tax, subject to eligibility. Importantly, this $2,000 is not deductible RRSP room — you cannot claim a tax deduction for contributions within this buffer. Keep this distinction in mind when planning contributions.

RRSP contributions during the first 60 days

RRSP contributions made in the first 60 days of a calendar year (typically January 1 to March 1) can be deducted for either the previous tax year or the current year, at your choice. This timing flexibility does not change your total deduction limit, but it affects which tax year you claim the deduction. This calculator estimates total room and does not determine the optimal deduction year for first-60-days contributions.

Where to find your official CRA RRSP limit

Your official RRSP deduction limit appears on your latest CRA Notice of Assessment or Notice of Reassessment. If you are a pension plan member, it may also appear on Form T1028. You can also view it in CRA My Account. Always verify your limit with the CRA before contributing, as this calculator provides only an estimate.

Frequently Asked Questions

What is the RRSP contribution limit for 2026?

The 2026 RRSP dollar limit is $33,810.00. However, your actual RRSP deduction limit depends on your prior-year earned income, unused room from prior years, and pension adjustments. The limit caps the new room generated each year at 18% of earned income, up to $33,810.00.

How is my RRSP contribution room calculated?

New RRSP room is generally 18% of your prior-year earned income, up to the annual dollar limit. Your total deduction limit adds unused room from prior years and subtracts pension adjustments (PA), while pension adjustment reversals (PAR) may add room. Net Past Service Pension Adjustments (PSPA) reduce room. This calculator estimates that total.

Does unused RRSP contribution room carry forward?

Yes. Unused RRSP deduction room carries forward indefinitely and accumulates each year. You can find your total unused room on your latest CRA Notice of Assessment or in CRA My Account.

What is a Pension Adjustment?

A Pension Adjustment (PA) is the value of pension benefits you earned in a registered pension plan or deferred profit-sharing plan during a tax year. It reduces the amount of new RRSP room you generate the following year, so pension plan members typically receive less RRSP room.

What is a Pension Adjustment Reversal?

A Pension Adjustment Reversal (PAR) restores RRSP room when you leave a pension plan before retirement and receive a payout of your contributions. It is designed to balance the RRSP room previously reduced by the PA for benefits you did not receive.

What happens if I contribute more than my RRSP deduction limit?

Contributions above your RRSP deduction limit become unused contributions that you can carry forward and deduct in a future year. Excess amounts are generally subject to a 1% per month tax on the highest excess in each month, but the CRA provides a lifetime $2,000 excess-contribution buffer before this tax typically applies.

Is the $2,000 RRSP over-contribution buffer extra contribution room?

No. The $2,000 buffer is not deductible RRSP room. It is a lifetime excess-contribution amount that may be tolerated before the 1% per month tax generally applies, subject to eligibility. You cannot claim a tax deduction for amounts within this buffer.

Where can I find my official RRSP deduction limit?

Your official RRSP deduction limit is shown on your latest CRA Notice of Assessment or Notice of Reassessment, on Form T1028 if you are a pension plan member, or in your CRA My Account. Always verify your limit with the CRA before contributing.

Do contributions in the first 60 days count for the previous year?

Contributions made in the first 60 days of a calendar year (typically January and February) can be deducted for either the previous tax year or the current year, at your choice. This calculator estimates total 2026 room and does not determine exact deduction timing for first-60-days contributions.

Can I contribute to a spousal RRSP using my contribution room?

Yes. You can contribute to a spousal RRSP using your own contribution room and claim the deduction on your tax return. The attribution rules may apply to withdrawals made within three calendar years of the contribution.
