Whose contribution room does a spousal RRSP use?

The contributor's. If you contribute to your spouse's RRSP, the amount comes out of your own RRSP deduction limit and you take the deduction. Your spouse's room is not affected.

What is the three-year rule?

If the annuitant spouse withdraws in the year a contribution was made or in either of the two following calendar years, the withdrawal is taxed to the contributor, up to the total contributed in those three years (Form T2205). It counts calendar years, not 36 months. A contribution in December 2026 is clear from January 1, 2029.

Can I contribute to a spousal RRSP after I turn 71?

Yes, if you still have room, until the end of the year your spouse turns 71. Your own RRSP must be closed or converted by the end of the year you turn 71, but a spousal plan runs on the spouse's age.

When is the deadline for a 2026 contribution?

Contributions made in the first 60 days of 2027 can be deducted on the 2026 return or the 2027 return. The CRA publishes the exact date on its important-dates page. Our data file records it as March 1, 2027 pending that confirmation.

Do I have to deduct a contribution in the year I make it?

No. Undeducted contributions carry forward for good and appear on your Notice of Assessment. If your income will be higher next year, contribute now for the tax-free growth and claim the deduction when your marginal rate is higher.

How much can I take out under the Home Buyers' Plan?

Up to $60,000 from your RRSPs, tax-free, if you are a first-time buyer. The money must have been in the RRSP for at least 90 days. For first withdrawals made from 2026 to 2028, the 15-year repayment begins in the fifth year after the withdrawal. Missed repayments are added to your income.

Can I use the Home Buyers' Plan and an FHSA for the same home?

Yes. The CRA's Home Buyers' Plan page confirms the two can be combined for the same home. The FHSA allows $8,000 a year to a $40,000 lifetime limit, deductible going in and tax-free coming out.

What is the Lifelong Learning Plan?

A withdrawal of up to $10,000 a year and $20,000 in total from your RRSP to pay for full-time education or training for you or your spouse, repaid over 10 years (ITA section 146.02).

Spousal RRSP Rules and the 3-Year Rule (2026)

This guide is part of Tax-saving strategies for Canadians (2026).

Who this is for

Couples whose retirement savings are lopsided, so one spouse will retire in a high bracket and the other in a low one. Anyone deciding which year to deduct a contribution. First-time buyers with RRSP savings. Adults going back to school.

How it works

Spousal RRSP. You contribute to a plan your spouse owns. The contribution uses your room and you deduct it at your marginal rate. In retirement your spouse withdraws and pays tax at their rate. The 2026 RRSP dollar limit is $33,810, and new room is 18% of the previous year’s earned income.

The three-year rule. If your spouse withdraws in the year of a contribution or in the next two calendar years, the withdrawal is taxed back to you, up to the contributions made in those three years (Form T2205).

The first-60-days rule. A contribution made in the first 60 days of a year can be deducted for the previous year or the current one. Undeducted contributions carry forward for good.

Home Buyers’ Plan. A first-time buyer can withdraw up to $60,000 from RRSPs tax-free to buy or build a qualifying home, and can combine it with an FHSA ($8,000 a year, $40,000 lifetime) for the same home. The money must have been in the RRSP for 90 days. For first withdrawals from 2026 to 2028, the 15-year repayment starts in the fifth year after the withdrawal.

Worked example: $100,000 and $40,000 spouses (Ontario, 2026)

Spouse A earns $100,000 and puts $10,000 into a spousal RRSP for spouse B, who earns $40,000 and expects a small pension. Tax figures use the 2026 federal and Ontario brackets in our data files.

Line	Amount
A’s marginal rate at $100,000	31.48%
Tax saved by A’s $10,000 deduction	$2,991 (29.91% effective)
Rate B would pay withdrawing it on $40,000 of retirement income	19.05%
Rate A would pay withdrawing it on $80,000 of retirement income	29.65%
Gap between the two withdrawal rates	10.60% of every dollar withdrawn

The deduction is the same whichever plan the money goes into. The spousal plan changes who pays tax on the way out. The same $10,000 contributed in February 2027 could be deducted on the 2026 return at 31.48%, or held for 2027 if A expects a higher bracket.

The rules that trip people up

Calendar years, not months. A withdrawal one day early is taxed to the contributor.
Room is the contributor’s. Spousal contributions reduce your own room and count toward your over-contribution limit. You get a cumulative $2,000 buffer, then a tax of 1% a month on the excess.
HBP and LLP repayments. Any required repayment you skip is added to your income for that year.
Pension adjustments. A workplace pension reduces your RRSP room through the pension adjustment on your T4. Check the Notice of Assessment before contributing.

What to do next

Enter the contribution in the RRSP refund calculator to see what it saves this year, then use RRSP vs TFSA vs FHSA to compare your rate today with the rate at withdrawal. The income tax estimator shows each spouse’s marginal rate. More strategies: Tax-saving strategies for Canadians (2026).
