The Old Age Security (OAS) program is one of Canada’s largest federal benefits, designed to provide financial assistance to seniors aged 65 and older. Unlike the Canada Pension Plan (CPP), which is based on contributions, OAS is funded by general tax revenue and is available to most seniors who meet residency and income requirements.
However, the Canada Revenue Agency (CRA) monitors OAS payments closely, and certain financial or tax-related issues can trigger red flags that result in reduced benefits — or in some cases, a temporary suspension. With growing pressure on federal finances and new rules being discussed for 2025 and beyond, seniors need to be aware of the main factors that could impact their monthly OAS income.
Here are the three key CRA red flags that could cause your OAS payments to be reduced or cut.
Old Age Security Is Going to Cut in the Future: What Seniors Need to Know
1. Exceeding the OAS Income Threshold
One of the biggest reasons seniors lose part or all of their OAS payment is due to the OAS Recovery Tax, often called the clawback.
For the 2024 tax year (payments affecting 2025), the OAS clawback begins when your net world income exceeds $90,997. For every dollar of income above that amount, 15 cents is deducted from your OAS benefit. Once your income reaches approximately $148,000, your OAS payment could be fully clawed back.
Examples of income that count toward this threshold include:
- CPP or other pension income
- Employment income
- Investment income (interest, dividends, capital gains)
- Rental income
- Withdrawals from RRSPs or RRIFs
Even one-time events — such as selling a property or taking a large RRSP withdrawal — can push your income high enough to trigger the clawback.
Tip: Seniors should plan withdrawals strategically, consider income-splitting with a spouse, and consult a financial advisor to manage taxable income levels and avoid unnecessary OAS reductions.
2. Not Filing Your Taxes on Time
Filing your annual tax return is essential to receiving OAS payments. The CRA uses the information from your tax return to determine your eligibility and calculate your monthly OAS amount.
If you miss the tax filing deadline or fail to report income properly, the CRA may suspend your payments until your information is updated. This is because the agency cannot verify your income level, which is crucial for determining whether a clawback applies.
In other words: No tax return means no verified income — and that can lead to missed payments.
To stay on track:
- File your tax return before April 30 each year (June 15 if self-employed).
- Make sure all sources of income are accurately reported.
- Review your Notice of Assessment to ensure there are no errors affecting your benefits.
Seniors who fail to file for multiple years may even be required to reapply for OAS, which can delay payments significantly.
3. Residency or Status Changes
The OAS program is designed primarily for Canadian residents, though some seniors who move abroad may still qualify for partial benefits depending on their time spent living in Canada.
To qualify for full OAS payments, you must have lived in Canada for at least 40 years after turning 18. If you’ve lived in Canada for between 10 and 39 years, you may still qualify for a partial pension.
However, moving outside of Canada or changing your residency status can trigger CRA reviews that lead to benefit adjustments or suspensions.
Key residency-related red flags include:
- Moving to another country for more than six months without notifying Service Canada.
- Failing to file taxes as a Canadian resident.
- Not updating your address or contact information with Service Canada and CRA.
- Returning to Canada after years abroad without re-establishing residency properly.
It’s also worth noting that non-residents are typically subject to a 25% withholding tax on OAS payments, although this can sometimes be reduced depending on Canada’s tax treaties with other countries.
Tip: Always inform Service Canada if your residency or marital status changes to avoid interruptions or overpayments that you may later have to repay.
How to Protect Your OAS Payments
While these CRA red flags can cause concern, seniors can take proactive steps to protect their benefits and avoid unexpected payment cuts:
- Keep your income under the clawback threshold whenever possible.
- File your taxes early each year to ensure your eligibility is up to date.
- Monitor your CRA MyAccount for any alerts or updates related to your benefits.
- Inform Service Canada immediately about any life or residency changes.
- Seek professional financial advice if you anticipate large one-time income events.
As federal spending pressures grow and policymakers debate changes to senior benefits, the CRA has become increasingly vigilant in monitoring OAS eligibility and payments. For many retirees, OAS is a critical part of their monthly income — and losing it due to avoidable red flags can create unnecessary financial hardship.
By understanding the top three CRA red flags — high income levels, missed tax filings, and residency changes — seniors can ensure they continue receiving their full OAS entitlement without disruption.
