The Old Age Security (OAS) program provides monthly payments to most Canadians aged 65 and older. However, many retirees are surprised to learn that these benefits can be reduced or even temporarily suspended if their income exceeds certain limits. This reduction—officially called the OAS Recovery Tax and often referred to as the OAS clawback—is administered by the Canada Revenue Agency (CRA).
For 2025, the government has updated income thresholds and policies that may affect how much OAS you receive. Here’s a detailed look at three key red flags that could trigger a clawback and what you can do to protect your payments.

1. Your Net Income Exceeds the 2025 Threshold
The most common reason for an OAS clawback is a net income that surpasses the annual threshold set by the CRA.
- For the July 2025 to June 2026 payment period, the income recovery threshold is $90,997.
- Once your net income—reported on line 23400 of your tax return—exceeds this amount, the CRA starts reducing your OAS at a rate of 15 cents for every dollar over the threshold.
If your income is high enough, your OAS could be reduced to zero for the year. This includes not just employment income but also RRSP withdrawals, capital gains, and certain investment earnings.
Tip: If you’re close to the threshold, consider strategies like splitting pension income with a spouse, timing RRSP/RRIF withdrawals, or using a Tax-Free Savings Account (TFSA) to generate non-taxable income.
2. Large One-Time Income Events
Even if you typically have modest retirement income, one-time financial events can unexpectedly trigger the clawback. Examples include:
- Selling a cottage or investment property and realizing a large capital gain
- Withdrawing a lump sum from your RRSP or RRIF
- Receiving a significant severance or bonus payment
These events can temporarily push your net income above the clawback threshold, leading to a higher OAS recovery tax for the following July–June payment cycle.
Tip: Plan large withdrawals or asset sales carefully. Consider spreading capital gains across multiple years or using the capital gains reserve when selling property to smooth out income and reduce clawback exposure.
3. Failure to Update or File Your Tax Return on Time
Your OAS payments are calculated based on the income you report to the CRA each year. If you fail to file your tax return by the deadline, or if you make significant errors, the CRA may:
- Suspend your OAS payments until accurate information is received
- Apply an automatic clawback based on estimated income, which may be higher than your actual earnings
Tip: File your taxes before the April 30, 2025 deadline, even if you owe nothing. Double-check income reporting and consider working with a tax professional to avoid miscalculations that could lead to unnecessary clawbacks.
How to Minimize or Avoid OAS Clawbacks
While you can’t control the government thresholds, you can take steps to protect your OAS payments:
- Use TFSAs: Earnings in a TFSA do not count toward taxable income.
- Split Pension Income: Couples can lower individual income levels by splitting eligible pension income.
- Strategic RRSP/RRIF Withdrawals: Plan withdrawals before age 65 or spread them over multiple years to avoid sudden spikes in income.
- Consider Deferring OAS: If you expect high income at age 65, deferring OAS up to age 70 can both increase your monthly payments and reduce the risk of early clawbacks.
The OAS clawback can be a shock for retirees who have worked hard to save for retirement. By understanding the 2025 rules and planning ahead, you can protect your monthly OAS payments and reduce the impact of the CRA’s recovery tax.
