Your RRSP deduction limit — the maximum you can contribute and deduct in a given tax year — is calculated by the Canada Revenue Agency and shown on your most recent Notice of Assessment. The formula is: 18% of your previous year’s earned income, to a maximum dollar ceiling, minus any pension adjustment from a workplace pension, plus any unused room carried forward from prior years.
For the 2026 tax year, the RRSP dollar ceiling is $33,810. This is the cap on new room generated from the 18% formula, regardless of income.
Quick Answer
An employee earning $90,000 in 2025 with no pension and no carried-forward room can contribute up to $16,200 (18% x $90,000) to their RRSP for 2026, well below the $33,810 ceiling. A $1,000 contribution at a 40% combined marginal rate saves $400 in tax that year.
RRSP Contribution Room Formula
New room for the current year = min(18% x prior-year earned income, annual dollar ceiling) minus pension adjustment.
Total available room = new room + unused room carried forward from all prior years.
You can find your total available room on line A of Schedule 7 of your T1 return, or in your CRA My Account under “RRSP and PRPP Deduction Limit.”
Annual RRSP Dollar Ceilings
| Tax year | Dollar ceiling |
|---|---|
| 2023 | $30,780 |
| 2024 | $31,560 |
| 2025 | $32,490 |
| 2026 | $33,810 |
The ceiling is indexed annually. Earned income that would generate more room than the ceiling (over $187,833 in 2026) is simply capped at the ceiling amount.
What Counts as Earned Income
Earned income for RRSP purposes includes employment income (T4 boxes 14 and 57-60), self-employment net income, rental income net of expenses, alimony received, and research grants. It does not include investment income (dividends, interest, capital gains), pension income, RRSP withdrawals, or Employment Insurance benefits.
Pension Adjustment
If you participate in a Registered Pension Plan (RPP) or Deferred Profit Sharing Plan (DPSP), a pension adjustment (PA) is reported in box 52 of your T4. The PA reduces your new RRSP room dollar-for-dollar to account for pension accruals. A PA of $10,000 on a $90,000 salary reduces new room from $16,200 to $6,200.
Worked Example
Ontario employee, 2026:
- 2025 employment income: $120,000
- 18% x $120,000 = $21,600 (below $33,810 ceiling)
- Pension adjustment (box 52): $5,400
- New room: $21,600 – $5,400 = $16,200
- Unused room from prior years: $12,000
- Total 2026 RRSP room: $28,200
- Combined marginal rate: 43.41%
- Tax savings on full $28,200 contribution: $12,242
The $2,000 Buffer
CRA allows a $2,000 lifetime over-contribution buffer above your deduction limit at any time, with no penalty. This buffer cannot be deducted — it simply avoids the 1% monthly penalty tax that applies to excess contributions above $2,000. Use it carefully: the buffer is a cumulative lifetime amount, not an annual allowance.
Spousal RRSP
You can contribute to a spousal RRSP using your own contribution room. The contribution reduces your deduction limit and generates a deduction for you, but the account belongs to your spouse. Withdrawals are eventually taxed in the spouse’s hands (with a 3-year attribution rule: withdrawals within 3 calendar years of any spousal contribution are taxed back to the contributor). Spousal RRSPs are a primary income-splitting tool for retirement.
Contribution Deadline
RRSP contributions for the current tax year can be made up to 60 days after December 31 of that year. For the 2026 tax year, the RRSP deadline is March 2, 2027. Contributions made January 1 to March 2, 2027 can be claimed on either the 2026 or 2027 return (not both).
Edge Cases and Rules
- RRSP accounts must be closed (converted to a RRIF, annuity, or lump-sum withdrawal) by December 31 of the year the account holder turns 71. No contributions can be made after that conversion.
- If you have a net past service pension adjustment (PSPA), it further reduces your available room and may require CRA approval before taking effect.
- Group RRSP contributions by payroll deduction count against the same deduction limit as personal RRSP contributions.
- Contributions to a PRPP (Pooled Registered Pension Plan) use the same deduction limit as RRSP contributions.
Frequently asked questions
- What is the RRSP contribution limit for 2026?
- The 2026 RRSP dollar ceiling is $33,810. Your personal limit is the lower of $33,810 or 18% of your 2025 earned income, minus any pension adjustment, plus unused room from prior years. The exact figure is on your 2025 Notice of Assessment.
- How is RRSP contribution room calculated?
- New RRSP room = min(18% of prior-year earned income, annual dollar ceiling) minus pension adjustment. Add any unused room carried forward from previous years for your total available deduction limit.
- Where do I find my RRSP deduction limit?
- Your RRSP deduction limit is shown on line A of Schedule 7 of your T1 return, on your Notice of Assessment, and in CRA My Account under 'RRSP and PRPP Deduction Limit.' It is updated each year after CRA processes your return.
- What is a pension adjustment and how does it affect RRSP room?
- A pension adjustment (PA) is the value of pension benefits accrued in a registered pension plan or DPSP, reported in box 52 of your T4. It reduces your new RRSP room dollar-for-dollar. A $10,000 PA on a salary that generates $21,600 of room leaves $11,600 in new RRSP room.
- Can I contribute to a spousal RRSP?
- Yes. You can contribute to a spousal RRSP using your own deduction limit. You receive the tax deduction; your spouse owns the account and is taxed on withdrawals (subject to the 3-year attribution rule). Spousal RRSPs are the primary income-splitting tool for retirement planning.
- What is the RRSP contribution deadline for 2026?
- The RRSP contribution deadline for the 2026 tax year is 60 days after December 31, 2026 — March 2, 2027. Contributions made between January 1 and March 2, 2027 can be applied to either the 2026 or 2027 return.
- What happens if I over-contribute to my RRSP?
- CRA allows a $2,000 lifetime over-contribution buffer with no penalty. Any excess above $2,000 is subject to a 1% monthly penalty tax on the highest excess amount during the month. The penalty is reported on form T1-OVP. The $2,000 buffer is cumulative over your lifetime, not an annual reset.
- Does rental income count as earned income for RRSP purposes?
- Yes. Net rental income (gross rents minus allowable expenses) is earned income for RRSP calculations. However, capital gains from selling rental property are not earned income and do not generate RRSP room.
- When must I close my RRSP?
- Your RRSP must be converted or closed by December 31 of the year you turn 71. Options include converting to a RRIF, purchasing an annuity, or withdrawing the full balance as a lump sum (fully taxable). No further contributions can be made after conversion.
- How much tax does an RRSP contribution save?
- Your tax savings equal the contribution amount multiplied by your combined federal-provincial marginal rate. A $15,000 contribution at a 43% marginal rate saves $6,450 in the year of contribution. The tax is deferred, not eliminated — RRSP withdrawals are taxable as income when made.
- Can I carry forward unused RRSP room?
- Yes. Unused RRSP deduction room carries forward indefinitely. If you contribute less than your limit in any year, the difference accumulates and can be used in future years. This is useful when income and marginal rates increase — making contributions more valuable in a later year.
