Guaranteed Income Supplement (GIS): Who Qualifies and How Much You Get

The Guaranteed Income Supplement is a monthly, non-taxable benefit paid to low-income Canadians who are already receiving Old Age Security. It was designed as a last-resort income floor for seniors who have little or no other retirement income beyond OAS itself.

The reason so many eligible Canadians miss it: GIS isn't automatic. You have to apply. And if you don't file a tax return — or file it late — you can lose months or years of payments you were entitled to.

Government benefit figures on this page reflect 2026 amounts and are updated annually. Verify current amounts at Canada.ca or Service Canada before making any decisions.

Who qualifies for GIS

To receive GIS, you must meet all three of these conditions:

1. You are 65 or older
2. You live in Canada
3. You are receiving Old Age Security (OAS)

You must also have income below the thresholds set by the federal government. Those thresholds depend on your marital status and your spouse's or partner's income and benefit situation.

Note: You do not need to have worked in Canada. You do not need a CPP history. If you're 65+, receiving OAS, living in Canada, and your income is low enough — you likely qualify.

Income thresholds (2026)

GIS eligibility and payment amounts are based on your annual income (excluding OAS itself). The income counted includes CPP, workplace pensions, RRSP/RRIF withdrawals, employment income, and most other sources. Your OAS pension is excluded from the calculation.

GIS is income-tested on a sliding scale — it doesn't disappear at the threshold. Instead, for every dollar of other income you have above zero, your GIS is reduced by 50 cents. This means most low-income seniors receive some GIS even if they have a small CPP or pension income.

GIS is not taxable — and that matters

One of GIS's most significant features is that it is completely non-taxable. Unlike CPP, OAS, and most pension income, GIS does not appear as income on your tax return and is never included in income calculations for other purposes.

This is meaningful: someone receiving $1,086/month in GIS on top of $727/month OAS has $1,813/month in government income — and the GIS portion doesn't get clawed back, taxed, or counted against other programs.

How GIS interacts with CPP

Here's something important that surprises many people: delaying CPP can sometimes reduce your GIS.

If you're in a low-income situation where you'll be eligible for GIS, taking CPP early (even with the reduction penalty) can be strategically sound — because once you start receiving CPP, it counts as income and reduces your GIS by 50 cents for every dollar. Starting CPP later means a higher CPP payment that displaces more GIS.

This doesn't mean early CPP is always right for low-income Canadians — the math depends on your specific situation, health, and other income sources. But it's a real dynamic that a financial advisor familiar with GIS planning should walk through with you before you decide on CPP timing.

How to apply

Some Canadians are enrolled in GIS automatically when they begin receiving OAS — Service Canada has access to your tax file and may be able to determine eligibility without an application. However, this is not universal, and you should not assume you'll be enrolled automatically.

The safest approach: apply directly. You can apply for GIS at the same time you apply for OAS, or separately after you're already receiving OAS. Applications are available through Service Canada online, by phone, or at a Service Canada office.

To apply, you'll need:

• Your Social Insurance Number (SIN)
• Your most recent tax return (or consent to allow Service Canada to access your tax data)
• Your spouse or partner's information if applicable

You must file taxes every year to keep GIS

GIS is renewed annually based on your prior year's tax return. If you don't file a tax return, Service Canada cannot confirm your income level and will stop your GIS payments.

This catches people off-guard. Many lower-income seniors don't think they need to file taxes — especially if their only income is OAS and GIS itself. But the filing requirement exists regardless. File a return every year, even if you owe nothing. Your GIS depends on it.

What happens if you leave Canada temporarily

GIS requires that you live in Canada. If you leave Canada for more than 6 months in a calendar year, your GIS payments will stop. They can be reinstated when you return and re-establish residency, but there is no retroactive payment for the period you were outside Canada.

Seasonal travel (wintering in the U.S., for example) for periods under 6 months generally doesn't affect GIS — but if you're approaching that limit, it's worth confirming your specific situation with Service Canada before you go.

The Allowance — for spouses who aren't yet 65

If you are 60–64 years old and your spouse or partner is receiving GIS, you may be eligible for a related benefit called the Allowance. It pays up to approximately $1,381/month (2026) to lower-income Canadians who are not yet old enough for OAS.

There is also an Allowance for the Survivor — for Canadians aged 60–64 whose spouse or partner has died. These programs are extensions of the GIS system and worth investigating if they apply to your situation.
