Worked Calculations and Checklists
RRSP deduction limit 2026 and how big your refund will really be
How your 2026 RRSP deduction limit is calculated ($33,810 cap), the March 1, 2027 deadline, a worked refund calculation, and when delaying the deduction pays off.
Your 2026 RRSP deduction limit is 18% of your 2025 earned income, up to a maximum of $33,810, minus your 2025 pension adjustment (if you are in a workplace pension plan), plus any unused room carried forward from earlier years. The exact figure is printed on your 2025 notice of assessment and in CRA My Account. Contributions made by March 1, 2027 can be deducted on the 2026 return. The tax saving is roughly the deduction multiplied by your marginal rate: for an Ontario employee at $75,000, a $5,000 contribution saves about $1,632.50.

How the 2026 limit is built
| Component | Where it comes from | Example (illustrative) |
|---|---|---|
| 18% of 2025 earned income | Salary, net self-employment and rental income, minus some deductions | 18% × $72,000 = $12,960 |
| Capped at the 2026 dollar limit | $33,810 for 2026 | Not reached |
| Minus 2025 pension adjustment (PA) | T4 box 52 if you belong to an RPP or DPSP | −$4,000 |
| Minus past service PA, plus PA reversal | T215 / T10 slips, if any | $0 |
| Plus unused room from earlier years | Notice of assessment | +$9,500 |
| 2026 RRSP deduction limit | $18,460 |
To earn the full $33,810 of new room for 2026, 2025 earned income had to be at least $33,810 ÷ 18% = $187,833. For 2027 the dollar limit is $35,390.
Earned income includes employment income, net self-employment income, net rental income, alimony or support received that is taxable, and some disability pensions. It does not include investment income, capital gains, pensions, RRSP/RRIF withdrawals, EI or OAS.
Worked example: the refund at $75,000 in Ontario
The employee from the take-home pay example has taxable income of $74,273 and contributes $5,000.
| Without RRSP | With $5,000 RRSP | |
|---|---|---|
| Taxable income | $74,273 | $69,273 |
| Federal tax | $8,258.60 | $7,233.60 |
| Ontario basic tax | $3,696.06 | $3,238.56 |
| Ontario Health Premium | $750 | $600 |
| Total income tax | $12,704.66 | $11,072.16 |
| Saving | $1,632.50 |
Of that saving, $5,000 × 29.65% = $1,482.50 comes from the bracket rate and $150 from the Health Premium step at $72,000. The contribution's after-tax cost is $5,000 − $1,632.50 = $3,367.50. The saving shows up as a bigger refund (or smaller balance owing) because withholding was based on salary without the RRSP; employer group RRSPs deducted at source give the saving on each paycheque instead.
The deadline and timing rules
- March 1, 2027: last day to contribute and deduct for 2026 (the first 60 days of 2027). Contributions made from March 2 count for 2027.
- You do not have to deduct in the year you contribute. You can contribute now and carry the deduction forward to a year with a higher marginal rate, for example the year after a promotion or a parental leave year ending. You report the contribution on Schedule 7 either way.
- The plan must mature by December 31 of the year you turn 71: convert to a RRIF, buy an annuity or withdraw (taxable).
- Spousal RRSP: you contribute and deduct using your room, your spouse owns the plan. If your spouse withdraws within roughly three calendar years of your last contribution, the withdrawal is taxed to you (attribution).
- Withdrawals are fully taxable, with tax withheld at source by the institution; the withholding is a prepayment, and the final tax depends on your rate that year.
When an RRSP deduction is worth more, or less
| Situation | Effect |
|---|---|
| Marginal rate now higher than in retirement | Classic case: deduct at 29.65% or more, withdraw later at a lower rate |
| Parent receiving the CCB | Lower net income raises the CCB (13.5% for two children in the middle band), so the effective saving is larger |
| Near the OAS recovery threshold ($95,323) | Deductions now help, but large RRIF withdrawals later may trigger the 15% recovery |
| Income in the 19.05% band (Ontario, $20k–$54k) | Modest saving; a TFSA may be more flexible |
| Planning to buy a first home | Consider the FHSA first: deductible like an RRSP, tax-free on a qualifying withdrawal |
| Very low income this year | Contribute if you want, but delay the deduction to a higher-income year |
Home Buyers' Plan and Lifelong Learning Plan
You can withdraw RRSP funds without tax under two programs, as long as you repay them:
- Home Buyers' Plan (HBP): up to $60,000 per person for a qualifying first home, repaid over 15 years (repayments normally start the second year after the withdrawal; for a first withdrawal made from 2022 to 2025 they start in the fifth year after it, so a 2022 withdrawal is first repaid in 2027). Missed repayments are added to income.
- Lifelong Learning Plan (LLP): up to $10,000 a year and $20,000 in total for full-time education of you or your spouse, repaid over 10 years.
Contributions made less than 90 days before an HBP or LLP withdrawal may not be deductible. You can combine the HBP with an FHSA for the same home.
Mistakes to avoid
- Over-contributing. You can exceed your limit by $2,000 without penalty; above that the excess costs 1% a month. See over-contribution penalties.
- Using last year's limit from memory. A pension adjustment or a new job changes it; check My Account.
- Spending the refund. The refund is partly a tax deferral; investing or using it to top up a TFSA keeps the plan working.
- Assuming withdrawals are taxed at the withholding rate. They are added to income and taxed at your marginal rate.
Frequently asked questions
Is there a minimum age for an RRSP?
There is no minimum age, but you need earned income reported on a return to build room. Many teenagers with part-time jobs file to start accumulating room.
Does an RRSP contribution reduce CPP or EI?
No. CPP and EI are based on gross employment earnings. Only income tax is reduced.
Can I contribute after I turn 71?
Not to your own RRSP, but if you still have room and earned income you can contribute to a spousal RRSP until the end of the year your spouse turns 71.
What about Quebec?
RRSP limits are federal and the deduction applies on the TP-1 too, at Quebec rates. The combined saving is therefore similar in structure.
