Form T746, Calculating Your Deduction for Refund of Unused RRSP, PRPP, and SPP Contributions, is the CRA form you use when you take out contributions you never deducted. You still include the withdrawal in income, but T746 works out an offsetting deduction you claim on line 23200, so the same contribution isn't taxed twice. The deduction is the smaller of your unused contributions and the amount you withdrew.
This guide follows the T746 E (25) version of the form and the CRA T746 page, as of October 2026. It applies to your own RRSPs, PRPPs and specified pension plans, and to contributions you made to a spouse's or common-law partner's RRSP or SPP.
What counts as an unused contribution
Unused contributions are ones you didn't deduct from your income. They often come from putting more into a plan than you could deduct, then asking for it back. Employer contributions to your PRPP don't count for this form.
The two conditions you have to meet
For the deduction, it has to be reasonable for the CRA to consider that one or both of these apply:
- You expected to be able to fully deduct the contributions in the year you made them or the year before.
- You didn't make the contributions intending to withdraw them later and claim the deduction.
There's a timing rule too. The withdrawal has to happen in the year you made the contribution or the following year, or in the year the CRA sent you a notice of assessment or reassessment for the contribution year, or the following year.
Part one: lines 1 to 4, your unused amount
- Line 1: the year you made the unused contributions. If they span more than one year, fill in lines 1 to 4 on a separate T746 for each year, then total the line 4 amounts on the most recent form.
- Line 2: all contributions you made that year to your own and your spouse's or partner's plans. Include direct transfers of lump sums only if you have to report them on your return.
- Line 3: the part of line 2 you've deducted or will deduct for any year.
- Line 4: line 2 minus line 3. That's your unused contribution for the year.
Leave out contributions designated as Home Buyers' Plan or Lifelong Learning Plan repayments, ones used to cancel HBP or LLP withdrawals, ones treated as not deductible because they were made in the 89-day period before an HBP or LLP withdrawal, and employer PRPP contributions.
Part two: lines 5 to 12, what you took out
Line 5 is the year of the withdrawal. Lines 6 to 11 pull the amounts from your slips, and each one also has to be reported as income on your return.
| Line | Where the amount comes from |
|---|---|
| 6 | Box 20 of your T4RSP slips, the refund of unused RRSP contributions |
| 7 | Box 22 of your T4RSP slips |
| 8 | Box 24 of your T4RIF slips |
| 9 | Lump sum PRPP withdrawals included in box 194 of your T4A slips |
| 10 | Box 18 of your T4A slips, only if it's a withdrawal from your SPP |
| 11 | Amounts you include in income from a spouse's or partner's RRSP, RRIF or SPP, from Form T2205 |
The form names the income lines for most of them. The T4RSP amounts on lines 6 and 7 go on line 12900. The PRPP and SPP amounts on lines 9 and 10 go on line 11500 if you're 65 or older at the end of the year, or line 13000 otherwise. On line 11, the RRSP amount goes on line 12900, and the SPP and RRIF amounts follow the same 11500 or 13000 rule.
Line 12 adds lines 6 to 11. On line 7, don't include any amount you designated as a qualifying withdrawal on Form T1006. If your withdrawal came from a RRIF, the T4RIF slip is where box 24 sits.
Line 13: the deduction
Line 13 is whichever is less, line 4 or line 12. That's your deduction, and it goes on line 23200 of your return.
How to file it
If you're filing on paper, attach the completed T746 and the T4RSP, T4RIF or T4A slips showing the withdrawals to your return for the year of the withdrawal. If you're filing electronically, keep the form and slips in case the CRA asks to see them.

If you want the plan issuer to pay the refund without tax taken off first, that's a different form. Form T3012A is the request for a tax deduction waiver on a refund of unused contributions, made before the withdrawal.
Notes that catch people out
- Once the CRA lets you deduct the withdrawn contributions, they stop being RRSP contributions, and you can't deduct them for any year.
- If you included them on Schedule 7 in an earlier year, ask for an adjustment to that year's return. It reduces the unused contributions you can carry forward.
- Don't enter the amount on Schedule 7 again when you fill in this year's return.
- You may have to pay tax if the amount on line 4 is more than $2,000, as of October 2026. The form points to Guide T4040 and Form T1-OVP for that.
Don't use T746 if the unused contributions were an excess transfer of a lump sum from a registered pension plan. That's Form T1043 instead.
The verdict
If you've taken back RRSP, PRPP or SPP contributions you never deducted, T746 is how you avoid paying tax on them twice. Gather the slips, work out line 4 for each contribution year, compare it with what you withdrew, and claim the smaller figure on line 23200.
Frequently asked questions
What is Form T746 for?
It calculates the deduction you can claim when you withdraw unused RRSP, PRPP or SPP contributions that you didn't deduct from income.
Where does the T746 deduction go?
On line 23200 of your income tax and benefit return.
Do I attach T746 to my return?
Only if you file on paper, with the T4RSP, T4RIF or T4A slips. If you file electronically, keep them in case the CRA asks.
Is the T746 deduction the full withdrawal?
It's whichever is less: your unused contributions on line 4 or the total withdrawn on line 12.
What's the difference between T746 and T3012A?
T3012A asks for no tax to be withheld on the refund before you withdraw it, while T746 works out the deduction on your return afterwards.
