Line 21000 of the Tax Return: Elected Split-Pension Deduction

On the Canadian T1 return, Line 21000 is where the transferring spouse or common-law partner claims the deduction for the elected split-pension amount. If you receive eligible pension income, you and your partner can jointly elect to move up to 50% of it onto their return, lowering your taxable income and usually the couple’s combined tax. The figure you enter on Line 21000 comes directly from Line 22 of Form T1032, Joint Election to Split Pension Income, and the receiving spouse reports the identical amount as income on Line 11600.¹

Who Can Make the Election

Both you and your spouse or common-law partner must be residents of Canada on December 31 of the tax year. If either of you dies during the year, residency is measured at the time of death. You also cannot have been living apart for 90 continuous days or more ending on or after December 31 because of a breakdown in the relationship. Separations for medical or work reasons don’t disqualify you.²

Both partners have to agree; one person cannot unilaterally push pension income onto the other’s return. Only one joint election is permitted per tax year, so if you both receive eligible pension income, you have to choose which one will be the transferring partner. The higher-bracket spouse usually transfers to the lower-bracket spouse, but the right call depends on each person’s full income picture and the effect on income-tested benefits.³

Which Pension Income Qualifies

What counts as eligible pension income depends on the transferring spouse’s age at year-end. At any age, life annuity payments from a registered pension plan qualify, which covers most employer-sponsored defined benefit pensions.²

Once the transferring spouse turns 65, the list expands to include:

RRIF withdrawals, including life income fund (LIF) payments
Annuity payments purchased with RRSP funds
Certain qualifying distributions from retirement compensation arrangements

Variable pension benefits paid from a money purchase provision of a registered pension plan or from a pooled registered pension plan qualify only once the transferring spouse is 65 or older at year-end.²

Some retirement income never qualifies for this election, regardless of age. Old Age Security, Canada Pension Plan and Quebec Pension Plan benefits, and U.S. Social Security payments received by Canadian residents cannot be split through Line 21000. RRIF amounts transferred to an RRSP, another RRIF, or an annuity are also excluded. CPP has its own separate sharing mechanism that works on different rules.²

Filing Form T1032

The joint election is made on Form T1032. You can allocate any amount from zero up to 50% of the transferring spouse’s eligible pension income. The form pulls figures from slips like the T4A or T4RIF and walks through the calculation step by step.⁴

Both spouses sign the same Form T1032. The elected amount from Line 22 goes to two places: the transferring spouse enters it as a deduction on Line 21000, and the receiving spouse reports the identical amount as income on Line 11600. The numbers must match exactly on both returns. A mismatch is one of the fastest ways to trigger a CRA review of both filings, and if the split is rejected the couple typically ends up with a higher combined tax bill plus interest on the unpaid balance.³

If you file electronically through NETFILE-certified software, Form T1032 is transmitted as part of both digital filing packages. Paper filers must attach a completed and signed copy to both returns, not just one. The form must be filed by the filing due date for the tax year.³

Deciding How Much to Split

The obvious benefit is moving income from a higher tax bracket to a lower one, but two other effects often matter more.

The receiving spouse may be able to claim the pension income amount on Line 31400, a non-refundable credit worth up to $2,000 of qualifying pension income. If the receiving spouse had no pension income of their own, the election itself can create eligibility for this credit. Step 4 of Form T1032 calculates the pension income amount for both spouses after the split. Even a modest split can be worth doing if it unlocks a credit that would otherwise go unclaimed.⁵

The bigger lever for many retirees is the Old Age Security recovery tax. For the 2026 tax year, once your individual net income passes $95,323, you lose 15 cents of OAS for every dollar above the threshold. Splitting pension income reduces the transferring spouse’s net income and can pull it below the clawback line.⁶

The trade-off is that the receiving spouse’s net income goes up, which can reduce their age amount, GST/HST credit, or other income-tested benefits. It matters especially when the receiving spouse gets the Guaranteed Income Supplement, since GIS eligibility is tied to reported income including Line 11600. Model the numbers both ways before you file.

Amending or Revoking the Election

You aren’t locked in. The CRA lets you amend the split amount or revoke the election entirely, provided you apply within three calendar years after the filing due date for the tax year the election covers. Both spouses have to agree to the change.²

To change the amount, submit a new completed and jointly signed Form T1032. To revoke the election, send a letter signed by both partners requesting the revocation. That flexibility is useful when you realize after filing that a different allocation would have produced a better result, or that the split cost you more in reduced benefits than it saved in tax.²

Penalties for False Reporting

Honest mistakes usually lead to a reassessment and interest on tax owing. Deliberate misreporting is treated differently. If you knowingly make a false statement or omission on your return, the gross negligence penalty is the greater of $100 or 50% of the understated tax related to that false statement. Inflating the eligible pension amount, or filing an election your spouse never agreed to, falls into that category.⁷
