Frequently asked questions
How much is the maximum OAS payment in 2026?
For the April to June 2026 quarter, the maximum is $743.05 per month at ages 65–74 and $817.36 per month at 75 and over (which includes the permanent 10% increase at age 75). Amounts are indexed to CPI quarterly — a further 1.2% increase is announced for July to September 2026.
What is the OAS clawback threshold for 2026?
The recovery tax applies at 15% of net world income above the annual threshold: $93,454 for 2025 income (affecting July 2026–June 2027 payments) and $95,323 for 2026 income. OAS is fully clawed back at roughly $152,062 (65–74) or $157,923 (75+) of 2025 income.
How much more do I get by deferring OAS to age 70?
Each month you defer past 65 adds 0.6% to your pension, up to a maximum of 36% at age 70 (60 months). At current rates that lifts the 65–74 maximum from $743.05 to about $1,010 per month, permanently. There is no benefit to deferring beyond 70, and you cannot receive GIS while deferring.
Do I get full OAS if I have not lived in Canada for 40 years?
No. A full pension requires 40 years of residence in Canada after age 18. Otherwise you receive a partial pension of 1/40th of the full amount per year of residence — for example, 20 years gives 50%. The minimum to qualify is 10 years of residence if you live in Canada, or 20 if you live abroad.
Is OAS taxable?
Yes, OAS is taxable income, unlike the Guaranteed Income Supplement (GIS), which is tax-free. High-income recipients also repay some or all of their OAS through the recovery tax, which Service Canada withholds from monthly payments during the July-to-June recovery period after the income year.
Who qualifies for the Guaranteed Income Supplement?
GIS tops up OAS for low-income pensioners living in Canada. For April to June 2026, a single pensioner with annual income under $22,512 (excluding OAS) can receive up to $1,109.85 per month tax-free. Couples have different cut-offs depending on whether the spouse receives OAS or the Allowance.
