The OAS Pension Split Tax Rule Change 2025 is set to impact thousands of senior Canadians who rely on pension income to manage their retirement. As of July 2025, the Canada Revenue Agency (CRA) has updated the guidelines around how couples can split eligible pension income to reduce tax burdens, especially in relation to Old Age Security (OAS) clawbacks and taxable thresholds.
The change is significant for those engaged in old age security tax planning update strategies, as it alters how income is reported and shared between spouses or common-law partners. The revised policy aims to close loopholes, promote fair tax treatment, and ensure that high-income pensioners do not unfairly avoid OAS benefit reductions.
Understanding the revised splitting rules, eligibility, and implications is crucial for retirees, tax planners, and financial advisors in 2025.
What Is the OAS Pension Split Rule?
The OAS Pension Split Tax Rule Change 2025 revolves around the practice of income splitting—a mechanism allowing seniors to transfer up to 50% of eligible pension income to a lower-income spouse for tax purposes. This has long been used to reduce total household tax liability and avoid OAS clawbacks, which begin when individual net income exceeds $90,997 in 2025.
However, the CRA’s latest old age security tax planning update adjusts how income splitting interacts with OAS eligibility calculations. Previously, some high-income seniors could avoid partial or full OAS repayment by redistributing income to a lower-earning spouse.
The 2025 change limits this benefit for households with a combined income above specific thresholds, ensuring that OAS clawback rules apply more equitably.
Key Changes in OAS Pension Income Splitting – 2025
| Feature | Before 2025 | After July 2025 Update |
|---|---|---|
| Pension Income Splitting Limit | Up to 50% to lower-income spouse | Same limit, but CRA recalculates OAS income |
| OAS Clawback Threshold (Individual) | $86,912 (2024) | $90,997 (2025) |
| Combined Household Cap | No household cap | Cap of $140,000 for split-income benefit |
| Tax Filing Implication | One partner reduces income significantly | Both partners’ OAS now considered jointly |
| Impacted Groups | High-income couples | High-income couples and early retirees |
This table outlines how the OAS Pension Split Tax Rule Change 2025 creates a more balanced system by adjusting how split income affects Old Age Security clawbacks.
Why Did the CRA Introduce This Change?
The old age security tax planning update introduced in 2025 stems from growing concerns that wealthier Canadians were disproportionately benefiting from income-splitting strategies. By transferring income, some couples avoided paying OAS repayments while still enjoying high combined household earnings.
The CRA’s objective with the new rule includes:
-
Improved fairness in how tax savings are distributed
-
Reduction in manipulation of income to avoid OAS clawbacks
-
Alignment with retirement equity principles for middle- and low-income seniors
-
Minimizing misuse of pension splitting among early retirees with private pension income
The CRA emphasized that regular pension income splitting will still be allowed, but its impact on OAS benefit retention will be reassessed through joint household evaluation.
Who Will Be Affected by the 2025 Rule Change?
The OAS Pension Split Tax Rule Change 2025 will primarily affect:
-
Retired couples with high combined pension income (over $140,000 annually)
-
Early retirees using private pensions to reduce taxes pre-65
-
Those near or above the OAS clawback threshold
For middle-income seniors with modest pension income, the impact will be minimal. However, it’s vital for those close to the OAS clawback range to consult a financial advisor to restructure their retirement strategy before the new rules take full effect.
Additionally, tax software and planners will be required to adapt their calculations to reflect CRA’s joint OAS income assessment model.
Conclusion
The OAS Pension Split Tax Rule Change 2025 brings necessary reform to the existing pension income splitting system by limiting how much high-income couples can benefit from avoiding OAS clawbacks. For retirees engaged in old age security tax planning update strategies, the new joint income assessment model represents a pivotal shift in CRA policy.
While income splitting remains a legal tax-reduction tool, its use in OAS planning will now be more regulated. Retirees are advised to review their income structures and consult with financial professionals to ensure compliance and tax efficiency under the new guidelines.
FAQs

The CRA will now assess OAS clawback eligibility based on combined household income after pension splitting, not just the individual’s net income.

No. The new rule mainly impacts high-income senior couples and those who previously used pension splitting to avoid OAS clawbacks.
