What Is Pension Income Splitting?
Pension income splitting lets married or common-law couples allocate up to 50% of eligible pension income from one spouse to the other on their tax returns. The money doesn't actually move — it's a paper transfer that shifts taxable income to the lower-income spouse, reducing the family's total tax bill.
It's done on paper using Form T1032 when you file your taxes. Both spouses must agree to the split, and you can adjust the percentage every year to optimize for that year's income.
What Income Qualifies?
Eligible (Any Age)
- • Company defined benefit pension
- • Life annuity payments from a registered plan
Eligible (Age 65+)
- • RRIF withdrawals
- • LIF/LRIF withdrawals
- • RRSP annuity payments
Not eligible: CPP, OAS, GIS, RRSP lump-sum withdrawals (before annuitization or RRIF conversion), employment income, and investment income outside registered accounts.
Note: CPP has its own sharing mechanism (CPP Sharing/Assignment) which works differently — it splits the actual CPP benefit, not just the tax reporting.
How the Split Works in Practice
Let's say one spouse has $80,000 in RRIF income and the other has $20,000 in OAS + CPP. Without splitting, the high-income spouse is in a 33% bracket while the low-income spouse is at 15%.
By splitting 50% of the $80,000 RRIF income, each spouse reports $40,000 from the RRIF. Combined with their other income, both spouses end up in the 20–25% bracket range instead of one being at 33% and the other at 15%. The family saves roughly $4,000–$6,000 per year.
The OAS Clawback Bonus
Here's the double win: splitting reduces the higher-income spouse's net income, which can push them below the OAS clawback threshold (~$93,454 in 2026). If you're getting clawed back, splitting pension income can restore thousands in OAS benefits on top of the income tax savings.
Using the SimRetire Pension Splitting Calculator
Our calculator lets you input both spouses' income sources and finds the optimal split percentage. It shows the tax bill with and without splitting, and highlights any OAS clawback savings.
Example: The Smiths Save $5,200
John (age 68) has $45,000 from a DB pension and $30,000 from his RRIF. Anne (age 66) has $15,000 from CPP and OAS. Total family income: $90,000.
Without splitting, John's taxable income is $75,000 (33% marginal rate) and Anne's is $15,000 (15% rate). By splitting 50% of John's $75,000 eligible pension income, John reports $37,500 and Anne reports $52,500. Both are now in the 20–25% range.
Result: The Smiths save approximately $5,200 in combined income tax, plus Anne now qualifies for the full pension income tax credit on the transferred amount.
Frequently Asked Questions
Can I split CPP income with my spouse?
CPP uses a separate mechanism called "CPP Sharing" where you apply to Service Canada to share actual CPP benefits. This is different from pension income splitting on your tax return. Both spouses must have been contributing to CPP, and both must apply.
Do I need to be 65 to split pension income?
For life annuity payments from a defined benefit plan, there's no age requirement. For RRIF, LIF, and RRSP annuity income, the splitting spouse must be 65 or older.
Does pension splitting affect GIS eligibility?
Yes. GIS is based on combined family income. Pension splitting changes reported income for both spouses, which could affect GIS. For lower-income retirees receiving GIS, splitting may actually reduce benefits. Always model both scenarios.
