If you’re already collecting Old Age Security (OAS) and your income is modest, there’s a good chance you qualify for extra money every month — and you may not even know it. The Guaranteed Income Supplement, or GIS, is one of the most under-claimed benefits for Canadian seniors, partly because a lot of people simply don’t realize it’s a separate program from OAS.
Below is a plain-English look at what GIS is, who can get it, how much it pays in 2026, and how to apply or keep it renewing automatically. If you’re helping an aging parent manage their finances, this is worth bookmarking too.
1. What Is the Guaranteed Income Supplement?
The Guaranteed Income Supplement is a non-taxable monthly benefit paid on top of Old Age Security to seniors with low income. It’s not a stand-alone pension. Think of it as a top-up that boosts your total monthly government income if your other income falls below certain limits.
A few key points:
- GIS is administered by Service Canada, and eligibility is checked using income information shared with the Canada Revenue Agency (CRA).
- Because it’s tax-free, you don’t pay tax on the amount you receive. You still have to file a tax return every year to keep it coming.
- You cannot receive GIS on its own. You must already be receiving the OAS pension before GIS can be added to your payment.
2. Who Qualifies for GIS in 2026
Eligibility comes down to four basic conditions:
- You are 65 or older.
- You are already receiving the OAS pension.
- You live in Canada (see the FAQ below for how long you can be away).
- Your income, or your combined income with a spouse or common-law partner, falls below the limit for your situation.
Your GIS eligibility and payment amount are worked out from the income on your tax return, which in practice means your previous year’s income. CPP, workplace pensions, RRIF withdrawals, investment income and most employment income all count toward the test. Your OAS pension itself is not counted, which is why the limits in the table below sit well above what OAS alone pays. If you receive a pension from outside Canada, check with Service Canada how it is assessed.
If your income has dropped because you retired or another pension was reduced or stopped, you can ask Service Canada to set your GIS using an estimate of this year’s income instead of last year’s.
One more rule: if you came to Canada under a sponsorship agreement, you generally cannot receive GIS while the agreement is in effect, apart from limited exceptions such as the sponsor having died. Canada.ca says that for sponsorships since October 1, 2025, this lasts for the entire length of the agreement. The exceptions are a sponsor who has died, been in prison for more than six months, been convicted of an offence against you, or declared personal bankruptcy.
3. 2026 Maximum Monthly Payment Amounts by Situation
GIS amounts are adjusted every January, April, July, and October to reflect the cost of living, and they don’t decrease if the cost of living drops. OAS was indexed up 1.4% for October to December 2026, and GIS follows the same quarterly schedule. Here are the current maximums and income limits from the official Canada.ca GIS page:
| Your situation (age 65+) | Annual income must be less than | Maximum GIS per month |
|---|---|---|
| Single, widowed or divorced | $23,112 | $1,138.90 |
| Spouse or partner receives the full OAS pension | $30,528 (combined) | $685.56 per person |
| Spouse or partner receives the Allowance | $42,768 (combined) | $685.56 per person |
| Spouse or partner receives neither OAS nor the Allowance | $55,392 (combined) | $1,138.90 |
These are maximums. Canada.ca says the maximum amounts are not guaranteed, and your actual payment depends on your income within each limit. The closer your other income gets to the limit, the smaller your GIS becomes.
Worked example: OAS plus GIS together
Take a single 70-year-old with a full OAS pension and almost no other income:
- OAS: $762.50 per month
- GIS (maximum): $1,138.90 per month
- Combined: $1,901.40 per month, or about $22,817 per year
For a couple where both partners receive full OAS and GIS at the couple rate, each person can receive up to $762.50 + $685.56 = $1,448.06, which is about $2,896 a month for the household. At 75 or older, the single maximum rises to $838.75 + $1,138.90 = $1,977.65 per month.
4. Income Cutoff Thresholds
The income limits in the table above are the other half of the equation. If your income (or combined income with a spouse) is at or above the limit for your category, GIS payments stop for that period. Use this quick check to see where you land:
- Single, widowed or divorced, income under $23,112: you likely qualify. If you aren’t receiving GIS yet, contact Service Canada.
- Couple, both receiving OAS, combined income under $30,528: you may both qualify at the couple rate.
- Spouse receives the Allowance (age 60 to 64), combined income under $42,768: the higher combined limit applies.
- Spouse receives neither OAS nor the Allowance, combined income under $55,392: the highest limit applies, with a maximum equal to the single rate.
- Over your limit: no GIS for now, but recheck if your income falls, since you can ask for an estimate based on this year’s income.
One thing that trips people up: you must file a tax return every year, by April 30, even if you had no income at all. Canada.ca warns that if you haven’t filed your 2025 taxes with the CRA, your GIS payments may stop or be reduced. Each year your benefit is reviewed using your federal tax return, and skipping a filing can pause your payments even if you would otherwise still qualify.
5. How to Apply or Renew
Some seniors are automatically enrolled in GIS after they apply for OAS, especially if Service Canada already has enough income information on file. You should get a letter shortly after your 64th birthday saying so. If a month has passed since your 64th birthday and no letter has arrived, contact Service Canada. Others need to apply manually.
To apply, you can:
- Apply online through your My Service Canada Account (MSCA), which Canada.ca lists as the preferred way, or
- Complete and mail a paper application to Service Canada (form ISP-3025 if you are applying for GIS only).
Renewal is based on your tax return. You generally don’t need to reapply each year as long as you file on time. In July you receive a letter saying whether your benefit is renewed at a new amount, stopped, starting or resuming, or whether Service Canada needs more income information. If the letter doesn’t arrive, call Service Canada and have your SIN and last year’s income ready.
If a payment seems late, or if your application is denied and you believe you qualify, you can request a reconsideration of the decision through Service Canada. Keep a record of your application date and any correspondence in case you need to follow up.
6. GIS Payment Dates and How It’s Paid
GIS follows the same payment schedule as OAS and CPP. Payments are made monthly, typically landing in the last few business days of each month, and are deposited directly into your bank account if you’ve set up direct deposit (which is strongly recommended for reliability). The October 2026 payment date listed on Canada.ca is October 28.
Because GIS is added directly to your OAS deposit, you’ll usually see it as one combined payment rather than two separate transactions.
7. Frequently Asked Questions
Does GIS affect other benefits like provincial senior supplements?
It can. Some provinces calculate their own senior supplements based partly on your federal income, including GIS. It’s worth checking with your provincial seniors’ benefits office to see how GIS interacts with any provincial top-ups you receive.
What happens to GIS if a spouse passes away?
The surviving spouse’s GIS amount is typically recalculated, since it moves from a “couple” income assessment to a “single” one. There is also a separate Allowance for the Survivor program for widowed individuals aged 60–64 who aren’t yet eligible for OAS (up to $1,726.18 a month for October to December 2026 if income is under $31,152). Contact Service Canada as soon as possible after a spouse’s passing to update your file.
Can GIS be received while living part-time outside Canada?
Not for long. Canada.ca says you cannot collect GIS if you are outside Canada for more than 6 months. Contact Service Canada before you leave for an extended trip, since that can prevent overpayments you would have to repay later, and contact them again when you return to restart your payments.
Is GIS taxable income?
No. Canada.ca describes GIS as a monthly, tax-free payment. You still need to file your tax return every year by April 30, because your benefit is reviewed using that return.
—
Bottom line: if you’re 65 or older, already receiving OAS, and living on a modest income, check whether GIS is topping up your payments, or whether you should be applying. For October to December 2026, a single senior with income under $23,112 can get up to $1,138.90 a month. File your taxes every year without fail, and recheck the official Canada.ca GIS page each quarter, since the amounts and income limits change.
