Use this free calculator to estimate your 2026 Old Age Security (OAS) pension with the Recovery Tax clawback. Enter your age, years of Canadian residency after 18, OAS start age, and estimated net world income to see your gross monthly OAS, the 15% clawback impact, and your net annual benefit — all updated instantly.
Old Age Security (OAS) is a monthly pension available to most Canadians aged 65 and older, funded from general tax revenues. Unlike CPP, it is not tied to your employment history — the amount depends on your years of Canadian residency after age 18, your OAS start age (65–70), and your net world income through the 15% Recovery Tax (clawback). This free online calculator shows your estimated gross monthly OAS, the clawback impact above the $95,323 threshold (2026), and your net annual benefit. Adjust your age, residency years, deferral choice, and income level to see how each factor affects your OAS pension.
The maximum monthly OAS pension for ages 65–74 is $743.05 (Q2 2026), and for ages 75+ it is $817.36 due to the 10% top-up. These amounts are indexed quarterly to the CPI and apply to residents with 40+ years of Canadian residency after age 18.
The OAS clawback is a 15% Recovery Tax on net world income above $95,323 (2026 threshold). For every dollar of income above that threshold, your OAS is reduced by 15 cents. At $154,708 (ages 65–74) or $160,647 (ages 75+), the clawback fully eliminates your OAS pension.
Yes, you can defer OAS for up to 60 months (age 70). Each month of deferral increases your pension by 0.6%, for a maximum 36% increase at age 70. Unlike CPP, OAS cannot be taken before age 65. Deferring can help offset the clawback if you have other retirement income.
You need at least 10 years of Canadian residency after age 18 to qualify for any OAS. The full pension requires 40 years. If you have fewer than 40 years, your OAS is prorated — for example, 20 years of residency gives you 50% of the maximum monthly amount.
