Understanding OAS in Canada
🇨🇦 What is Old Age Security?
Old Age Security is a monthly pension paid by the federal government to Canadians 65 and older. Unlike CPP, OAS is not based on employment history — it's based on how long you've lived in Canada after age 18. You need a minimum of 10 years in Canada to qualify for partial OAS, and 40 years for the full amount. OAS is taxable income and is indexed to inflation quarterly.
📊 2026 OAS Key Numbers — July–September 2026 Quarter
OAS and GIS amounts are indexed to inflation every January, April, July, and October — they are not fixed for the full year. The dollar figures below are for the July–September 2026 quarter; check canada.ca for the current quarter's amounts. The clawback threshold below is based on 2026 income and applies to OAS payments from July 2027 to June 2028 — not to what you're being paid right now. The payments you're actually receiving this quarter (July–Sept 2026) were clawed back based on your 2025 income instead, using a different threshold ($93,454) — see the FAQ below for both.
| Maximum monthly OAS (age 65–74) | $751.97 |
| Maximum monthly OAS (age 75+) | $827.17 |
| Clawback threshold (2026 income, applies July 2027–June 2028) | $95,323 |
| Clawback rate | 15% of income above threshold |
| Deferral bonus (per month after 65) | +0.6% (max +36% at 70) |
| Full eligibility | 40 years in Canada after 18 |
| Maximum GIS (single) | $1,123.17/month |
| Maximum GIS (each spouse in couple, both full OAS) | $676.09/month |
⏰ Should You Defer OAS?
Deferring OAS past 65 increases your monthly benefit by 0.6% per month — 7.2% per year — up to a maximum of 36% more at age 70. The break-even point for deferring from 65 to 70 is approximately age 82–83. If you have other income sources (CPP, pension, RRIF) and don't need OAS at 65, and if you're in good health, deferring to 70 typically results in significantly more lifetime income. However, if you have a lower income and may qualify for GIS, taking OAS at 65 is usually better since GIS is reduced dollar-for-dollar by OAS income.
💸 OAS Clawback Explained
OAS recovery tax runs about 18 months behind the income it's based on. For OAS payments you're receiving right now (July 2026–June 2027), the clawback was based on your 2025 net income: it starts above $93,454, and OAS is fully eliminated at $152,062 (age 65–74) or $157,923 (age 75+). For the next payment period (July 2027–June 2028), clawback will be based on your 2026 net income: it starts above $95,323, with full elimination currently estimated at approximately $155,109 (age 65–74) or $161,088 (age 75+) — these two figures are estimates since they depend on OAS payment amounts not yet finalized for that period. Either way, the rate is 15 cents of clawback per dollar of income above the threshold. The clawback is applied as a withholding tax through the payment year. Strategies to reduce clawback include income splitting with a spouse, RRSP/RRIF withdrawal timing, and TFSA-first withdrawal strategies.
🌍 OAS for Newcomers and Immigrants
If you immigrated to Canada later in life, you may still qualify for partial OAS based on the years you have lived in Canada after age 18. Each year of Canadian residency equals 2.5% of the full OAS amount — so 10 years gives you 25%, 20 years gives you 50%, and so on up to 40 years for the full pension. You must have lived in Canada for at least 10 years after age 18 to collect OAS while living in Canada. If you have lived in a country that has a social security agreement with Canada, those years may count toward your eligibility. Countries with agreements include the United States, United Kingdom, Australia, and many others. Contact Service Canada to find out if your home country qualifies.
🛡️ Strategies to Reduce OAS Clawback
If your net income is above or near the $95,323 clawback threshold, there are legitimate strategies to reduce your taxable income and preserve more of your OAS. Pension income splitting with a spouse can move up to 50% of eligible pension income — including RRIF withdrawals and CPP — to your spouse's return. TFSA withdrawals are not included in net income and do not affect OAS, making them an ideal source of retirement income for high earners. Converting RRSP savings to a TFSA before age 71 reduces future RRIF minimum withdrawals. Charitable donations and medical expenses can also reduce net income. Planning the timing of RRSP-to-RRIF conversion and RRIF withdrawals across years can help keep income below the threshold in key years.
❓ Frequently Asked Questions About OAS
Do I have to apply for OAS or is it automatic?
OAS is not automatic for everyone. Some Canadians are enrolled automatically and receive a letter from Service Canada the month after their 64th birthday. If you do not receive a letter, you must apply. You can apply online through My Service Canada Account or by paper application. Apply at least 6 months before you want payments to begin to avoid delays.
Can I receive OAS if I live outside Canada?
Yes, if you are 65 or older, a Canadian citizen or legal resident, and have lived in Canada for at least 20 years after age 18, you can receive OAS while living abroad. If you have fewer than 20 years, you can only receive OAS while residing in Canada or in a country with a social security agreement with Canada.
Is OAS affected by CPP income?
Yes indirectly. OAS itself is not based on CPP, but your CPP income counts toward your net income for the OAS clawback calculation. If your total net income — including CPP — exceeds $95,323, your OAS will be reduced by 15 cents for every dollar above that threshold.
What is the difference between OAS and GIS?
OAS is a universal pension available to all eligible Canadians 65 and older — it is taxable income. GIS is an additional non-taxable benefit for low-income OAS recipients. You must already receive OAS to receive GIS. GIS is income-tested and reduces as your other income increases, phasing out entirely when your income reaches approximately $25,000 per year for singles.
