OAS / GIS Calculator 2026

Canadians 65+ who have lived in Canada for at least 10 years after age 18 qualify. Full OAS requires 40 years of Canadian residence after age 18. You receive a prorated amount (years/40) if you have fewer than 40 years.

If your net income exceeds $95,323 in 2026, you must repay 15% of the amount above this threshold, up to your full OAS benefit. The repayment is made via your income tax return and reduces future OAS payments.

Deferring OAS increases your monthly benefit by 0.6% per month (7.2%/year), up to a maximum of 36% at age 70. Deferring makes sense if you have other income sources before 70 and you expect to live into your mid-80s or beyond.
