Frequently Asked Questions

Everything you need to know about Old Age Security

You may be eligible for OAS if you are 65 years of age or older and have lived in Canada for at least 10 years after turning 18. For a full OAS pension, you need 40 years of Canadian residency after age 18. If you lived in Canada between 10 and 40 years, you receive a partial pension calculated as 1/40th of the full amount for each year of residency. Canadian citizens or legal residents living abroad may also qualify under international social security agreements.
The OAS clawback, officially called the OAS recovery tax, reduces your OAS pension if your net income exceeds $90,997 (2025). For every dollar of income above this threshold, your OAS is reduced by 15 cents. The OAS pension is fully eliminated when income reaches approximately $148,451 for seniors aged 65-74, or higher for those 75 and over. The clawback is applied at source through monthly withholding or through your tax return.
Yes, you can defer OAS for up to 60 months (5 years) past age 65. For each month you defer, your pension increases by 0.6%, for a maximum increase of 36% at age 70. This can be beneficial if you have other income sources between 65-70 or if your income would trigger the clawback. Once you start receiving OAS, the deferral increase is permanent and applies for life.
Since July 2022, OAS pensioners aged 75 and over automatically receive a 10% permanent increase to their pension. The maximum monthly OAS for those 75+ is $800.44 (Q1 2025), compared to $727.67 for those aged 65-74. This increase is applied automatically and you do not need to apply for it separately.
Canada has social security agreements with over 60 countries. These agreements can help you qualify for OAS by counting your years of residency or social security contributions in another country toward the 10-year minimum. However, the partial pension calculation is still based only on your actual years of Canadian residency. Some agreements also allow you to receive OAS while living in the other country.
Yes, OAS is fully taxable income. You will receive a T4A(OAS) slip each year showing the amount of OAS received and any tax withheld. You can request that tax be deducted at source from your OAS payments to avoid a large tax bill at filing time. The OAS recovery tax (clawback) is calculated separately from regular income tax.
OAS payments are reviewed and adjusted quarterly (January, April, July, and October) based on the Consumer Price Index (CPI). Payments can increase to keep up with inflation but will never decrease even if the CPI falls. This quarterly indexation ensures that the purchasing power of OAS is maintained over time.

CRA-Aligned: This calculator uses official Service Canada OAS rates for Q1 2025. Actual pension amounts are adjusted quarterly based on the Consumer Price Index. For a definitive assessment, contact Service Canada.

Understanding Old Age Security in Canada

How OAS provides retirement income to Canadian seniors

What is Old Age Security?

Old Age Security (OAS) is a monthly payment from the federal government for Canadians aged 65 and older. Unlike CPP, you do not need to have worked or made contributions to receive OAS. For 2025, the maximum monthly OAS payment is about $727 for those aged 65 to 74, and about $800 for those aged 75 and older.

Who is eligible for OAS?

You must be 65 or older and a Canadian citizen or legal resident. If you live in Canada, you need at least 10 years of residence after age 18 for a partial pension, or 40 years for the full pension. If you live outside Canada, you need at least 20 years of residence after age 18. Each year of residence earns you 1/40th of the full pension.

What is the OAS clawback?

If your net income exceeds $90,997 (2025 threshold), you must repay part of your OAS. The clawback rate is 15% of income above the threshold. For example, if your income is $100,997, you repay 15% of $10,000 = $1,500 per year. If your income exceeds about $148,000, the entire OAS pension is clawed back to zero.

Can you defer OAS for a higher payment?

Yes. You can defer OAS for up to five years past age 65. For each month you delay, your pension increases by 0.6% — that is 7.2% per year. If you defer to age 70, your OAS is 36% higher than if you started at 65. On a maximum pension of $727, deferring to 70 would increase it to about $989 per month. This makes sense if you have other income to live on until 70.

Is OAS taxable?

Yes. OAS payments are taxable income and must be reported on your tax return. Tax is not withheld automatically from OAS payments unless you request it or the CRA determines you owe the OAS recovery tax (clawback). You can request voluntary tax deductions from your OAS to avoid a large tax bill at filing time.

What is the OAS increase at age 75?

Since 2022, OAS payments automatically increase by 10% when you turn 75. This means the maximum monthly OAS for those 75 and older is about $800, compared to $727 for those aged 65 to 74. This increase was introduced to help older seniors who face higher healthcare and living costs as they age.

How do you apply for OAS?

In many cases, Service Canada automatically enrols you for OAS. You will receive a letter the month after you turn 64 informing you of your automatic enrolment. If you are not automatically enrolled, you can apply online through My Service Canada Account, by mail using Form ISP-3550, or in person at a Service Canada centre. Apply at least six months before you want payments to start.
