The CRA allows eligible couples to split up to 50% of qualifying pension income.
That does not mean 50% is always the best choice.
A full split may reduce tax for the higher-income spouse while pushing the other spouse into a higher tax bracket. It may protect one person’s OAS and create a recovery tax for the other. It can improve one tax credit while reducing another.
The best pension income split is the amount that produces the strongest combined result for the household—not automatically the largest amount permitted.
What Does the 50% Limit Mean?
Pension income splitting allows an eligible pension recipient to jointly elect with a spouse or common-law partner to allocate up to half of qualifying pension income for tax purposes.
The original pension recipient is the transferring spouse.
The other person is the receiving spouse.
The election can be any amount from zero up to the maximum calculated on Form T1032. It does not have to equal exactly 50%.
For example, a couple may choose to split:
- 10%
- 25%
- 37%
- 50%
- A specific dollar amount below the maximum
The election is made annually, so the amount can change from year to year.
Why 50% Often Appears Attractive
Canada’s tax system uses graduated rates.
When one spouse has substantially more taxable income than the other, shifting eligible pension income may reduce the amount taxed at the higher spouse’s marginal rate.
For example:
Before pension splitting
- Spouse A: $100,000
- Spouse B: $30,000
After a $25,000 split
- Spouse A: $75,000
- Spouse B: $55,000
This may reduce combined tax because more household income is reported by the lower-income spouse.
The precise result depends on the province, deductions, credits and other income.

Equal Income Is Not Always the Goal
Couples sometimes assume the ideal result is to make both spouses’ incomes exactly equal.
That can be a useful starting point, but it is not a universal rule.
The optimal split may be affected by:
- Tax brackets
- OAS recovery tax
- Age amount
- Pension income amount
- Medical expenses
- Charitable donations
- Spousal amount
- Provincial tax credits
- Income-tested benefits
- Capital gains
- RRIF withdrawals
A slightly uneven income allocation may produce a lower combined tax bill.
The Pension Income Amount Can Change the Result
Eligible pension recipients may be able to claim the federal pension income amount on up to $2,000 of qualifying income.
Pension splitting may allow the receiving spouse to claim some or all of this amount when the eligibility requirements are satisfied.
However, the CRA notes that pension income qualifying for the transferring spouse’s pension income amount does not necessarily qualify for the receiving spouse in every case because eligibility can depend on age and income type.
A smaller split may be enough to give the receiving spouse access to the available credit without transferring the full 50%.
OAS Recovery Tax Can Make a Smaller Split Better
OAS is subject to a recovery tax when a recipient’s net world income exceeds the annual threshold.
For the 2025 income year, the threshold is $93,454. The federal government currently lists an estimated 2026 income-year threshold of $95,323 for the July 2027 to June 2028 recovery period. The final 2026 threshold will be confirmed later.
Suppose the transferring spouse’s income is only $10,000 above the applicable threshold.
A pension split large enough to bring that spouse below the threshold may protect the OAS payment.
Splitting additional income after that point may provide less benefit and could create new tax or benefit consequences for the receiving spouse.
A Full Split Can Push the Receiving Spouse Into OAS Recovery
When both spouses receive OAS, reducing one spouse’s income while increasing the other’s must be evaluated carefully.
Suppose:
- Spouse A has income of $115,000.
- Spouse B has income of $85,000.
- The applicable OAS threshold is approximately $95,000.
Allocating $20,000 from A to B could produce:
- Spouse A: $95,000
- Spouse B: $105,000
Spouse A’s recovery-tax exposure may fall, while Spouse B may now face recovery tax.
A smaller split could produce a better combined result.
How the OAS Recovery Tax Is Calculated
The recovery tax is generally 15% of the recipient’s income above the applicable threshold, up to the amount of OAS that must be repaid.
For example, using the official 2025 threshold of $93,454:
Income: $100,000
Excess income: $6,546
Recovery tax: $6,546 × 15% = $981.90
The recovery tax affects later monthly OAS payments through deductions based on the prior income year.
A pension split can reduce the transferring spouse’s net income, but it raises the receiving spouse’s net income by the same amount.
The Age Amount Can Be Affected
The federal age amount is an income-tested tax credit available to qualifying individuals who are at least 65.
As net income rises, the credit is gradually reduced.
Pension splitting could:
- Preserve more of the transferring spouse’s age amount
- Reduce the receiving spouse’s age amount
- Shift which spouse receives more benefit
- Produce little net household improvement
Provincial and territorial age credits may have separate thresholds and calculations.
The tax projection should consider both spouses rather than looking only at the transferring spouse’s return.
The Spouse or Common-Law Partner Amount Can Change
When one spouse has low income, the other may be able to claim a spouse or common-law partner amount.
Allocating pension income to the lower-income spouse can reduce or eliminate that claim.
The tax saved through pension splitting may still exceed the lost credit, but the effect should be included.
The CRA notes that pension splitting can affect credits calculated using one taxpayer’s income, including the age amount, spouse or common-law partner amount and OAS repayment.
Household-Based Credits May Not Change
Some benefits use the combined net income of both spouses.
Because pension splitting lowers one spouse’s income and raises the other’s by the same amount, combined family income does not change.
The CRA uses the GST/HST credit as an example of a benefit that generally does not change solely because of pension splitting when it is calculated from combined family income.
This does not mean every federal, provincial or territorial program is unaffected.
Some programs use individual income, while others use household income.
Medical Expenses Can Affect the Best Split
Medical expenses are often claimed by the spouse for whom the credit produces the greatest result.
The available medical-expense credit is affected by a threshold connected with the claimant’s income.
Reducing one spouse’s net income may improve the value of a medical-expense claim.
Increasing the other spouse’s income may make that spouse less favourable as the claimant.
Before finalizing the pension split, determine:
- Which spouse will claim medical expenses
- Which expenses qualify
- The selected 12-month claim period
- Each spouse’s income after splitting
- Provincial medical-expense rules
The best split may change when large dental, prescription or long-term care expenses occur.
Charitable Donations Can Affect the Calculation
Charitable donations can usually be combined and claimed by one spouse.
Donation-credit rates can depend partly on taxable income and donation amounts.
A pension split that lowers the higher-income spouse may change which person should claim the donations.
The donation strategy should therefore be calculated together with the pension split.
Capital Gains Can Change the Best Percentage
A retiree may have an unusually high-income year because of:
- Sale of investments
- Sale of a cottage
- Business disposition
- Fund distributions
- Realized capital gains
- Taxable pension lump sums
A 50% pension split could be valuable in that year even when a smaller split was optimal previously.
The following year, with no major capital gain, the ideal percentage may fall.
This is why pension splitting should be reviewed annually.
RRIF Withdrawals Can Change the Result
RRIF income can qualify for pension splitting when the recipient meets the applicable age or survivor requirements.
The amount withdrawn from a RRIF may vary each year.
A large withdrawal can:
- Move the owner into a higher tax bracket
- Increase OAS recovery tax
- Reduce age credits
- Increase the amount available for pension splitting
The solution may involve coordinating:
- RRIF withdrawal amount
- Pension split
- CPP and OAS timing
- TFSA withdrawals
- Non-registered income
The split should not be calculated in isolation after all other retirement-income decisions have already been made.
One Spouse May Have Employment Income
A spouse can receive eligible pension income while still working.
When the other spouse also has employment income, transferring the full 50% may move pension income into an equal or higher marginal tax bracket.
For example:
- Retired spouse pension income: $70,000
- Working spouse employment income: $65,000
A large split may provide little tax savings and could make the working spouse’s return more expensive.
Test the actual combined result.
One Spouse May Be Under Age 65
The receiving spouse can be younger than 65.
However, age can affect whether the allocated pension income qualifies for the pension income amount.
The CRA warns that the transferring spouse’s qualifying pension does not automatically create the same pension-income-credit eligibility for the younger receiving spouse.
The split may still reduce tax through lower brackets, but the credit result can differ.
Both Spouses May Have Eligible Pension Income
Only one joint pension-splitting election can be made for the year.
When both spouses have eligible pension income, determine:
- Which spouse should transfer
- How much should be transferred
- Whether no split is better
- Whether changing RRIF withdrawals would improve the result
The higher-pension spouse is often selected as the transferring spouse, but other income and credits may reverse that decision.
Withholding Tax Does Not Determine the Best Split
Pension providers withhold tax from the original recipient’s payments.
Form T1032 reallocates the relevant withholding in proportion to the elected split.
For example, a 30% split generally transfers 30% of the related pension withholding to the receiving spouse’s tax return.
The amount withheld is only a tax prepayment.
Do not choose the split based on which spouse appears to be receiving a refund before the withholding allocation is completed.
An Illustrative Comparison
Suppose one spouse receives $80,000 of eligible employer pension income and the other receives $30,000 from other sources.
The couple could compare:
No split
- Spouse A: $80,000
- Spouse B: $30,000
25% split
- Spouse A: $60,000
- Spouse B: $50,000
40% split
- Spouse A: $48,000
- Spouse B: $62,000
50% split
- Spouse A: $40,000
- Spouse B: $70,000
The 25% or 40% split could produce a better result than 50%, depending on:
- Provincial rates
- Age credits
- OAS
- Pension credits
- Medical expenses
- Other deductions
Use tax software or professional calculations to compare the actual total payable.
When a 50% Split May Work Well
A full split may be effective when:
- One spouse has substantially more taxable income
- The receiving spouse has very little income
- The transferring spouse faces OAS recovery tax
- The receiving spouse remains below recovery thresholds
- Both spouses can make use of pension-related credits
- No major individual-income-tested benefits are lost
- The tax brackets are meaningfully different
Even in these circumstances, calculate the combined result.
When a Smaller Split May Work Better
A smaller split may be preferable when:
- Only enough income needs to move to reach a lower tax bracket
- The transferring spouse only needs to get below the OAS threshold
- A full split would reduce the receiving spouse’s age amount
- A spouse credit would be lost
- The receiving spouse has employment or business income
- Both spouses already have similar taxable incomes
- Provincial benefit thresholds are involved
- Medical-expense planning favours a particular income level
When No Split May Be Best
No pension split may be appropriate when:
- The receiving spouse already has higher income
- Both spouses fall within similar tax ranges
- The transferred amount would reduce valuable credits
- The income does not qualify
- The couple was not eligible to make the election
- The administrative adjustment would produce no meaningful benefit
The election is optional.
Questions to Test Before Choosing 50%
- What is each spouse’s taxable income before splitting?
- Which income qualifies?
- Which spouse should transfer?
- What happens at 10%, 25%, 40% and 50%?
- Does either spouse receive OAS?
- How much recovery tax applies under each option?
- Does either spouse lose the age amount?
- Does a spouse credit change?
- Who should claim medical expenses?
- Who should claim charitable donations?
- Are there large RRIF withdrawals?
- Are there capital gains?
- Does one spouse still work?
- Which provincial programs are affected?
- What is the combined tax—not merely each person’s refund?
