Guaranteed Income Supplement (GIS): A Plain-Language Guide for Seniors

If money is tight in retirement, the Guaranteed Income Supplement is one of the most important benefits to know about, and one that too many seniors quietly miss out on. It is a monthly, non-taxable top-up for lower-income seniors, and it can make a real difference in covering rent, groceries, and care.

This guide explains what GIS is, who qualifies, how much you might receive, and the one thing you must do every year to keep it. If you are helping a parent on a modest income, this is worth ten minutes.

What the Guaranteed Income Supplement is

The Guaranteed Income Supplement, or GIS, is a monthly payment that tops up Old Age Security for seniors with little or no other income. Unlike OAS and the Canada Pension Plan, GIS is non-taxable, so every dollar stays in your pocket.

It is designed to make sure older Canadians have a basic income floor. The amount is income-tested, which means it goes down as your other income goes up, and it stops once your income passes a yearly threshold. You can read the official overview on the Government of Canada's GIS page.

The detail that trips people up is simple: GIS is tied to OAS. You have to be receiving Old Age Security first in order to get the supplement.

Who qualifies for GIS

To receive the Guaranteed Income Supplement, you generally need to:

• Be 65 or older and already receiving Old Age Security.
• Live in Canada.
• Have an annual income below the threshold set for your situation.

The income limit depends on whether you are single, or married or common-law, and on whether your partner also receives OAS or the Allowance. Because it is income-tested, even a modest pension or some part-time work can change the amount. The official GIS eligibility page lists the current thresholds, which are updated over time.

How much GIS can you get?

The amount is based on your income and your marital status, so it varies a lot from person to person. Someone whose only income is OAS receives the most, while the supplement gradually decreases as other income rises.

Because the figures are refreshed every few months and depend on your situation, the 2026 amounts may differ from what a neighbour quoted last year. The best way to know your own number is to check the official GIS payment amounts page or sign in to your My Service Canada Account. If GIS is part of a care budget, it helps to see it next to real costs in our complete care guides and listings across Canada.

How to apply for GIS

For many people, GIS is handled automatically. When you are enrolled in OAS, Service Canada often assesses you for GIS at the same time, using your tax information, and lets you know if you qualify.

That said, do not assume. If you did not get a letter, or your income has recently dropped, you may need to apply. You can do it online through your My Service Canada Account, or with a paper GIS application. It is always worth applying if there is any chance you qualify, because it is not automatic for everyone.

The one thing you must do every year

Here is the single most important point in this guide: file your income tax return every year, on time, even if you had no income at all.

GIS is renewed automatically each year based on your tax return. If you do not file, your payments can stop, and getting them restarted is a hassle nobody wants. This is the most common way seniors lose their GIS by accident. Filing is free at many community volunteer tax clinics, so help is available. Put a reminder in the calendar each spring, and your supplement keeps flowing.

The Allowance and the Allowance for the Survivor

GIS has two close cousins for people aged 60 to 64, the years just before OAS begins.

• The Allowance is for 60 to 64 year olds whose spouse or common-law partner receives the GIS. It helps bridge the gap until you reach 65. See the Allowance details.
• The Allowance for the Survivor is for 60 to 64 year olds with a low income whose spouse or partner has died. See the Allowance for the Survivor details.

Both are worth checking if they describe your situation, since they can offer real support in those in-between years.

GIS payment dates and how it is paid

GIS is paid monthly, together with your OAS, on the same schedule as the Canada Pension Plan. The government publishes the benefit payment dates for the year, so you always know when to expect it.

As with the other benefits, direct deposit is the safest way to receive it. You can set it up or update it in your My Service Canada Account or by phone, and if you switch banks, update your details right away.

Extra benefits GIS can unlock

GIS is valuable on its own, but it can also open doors to other help. Many provinces and territories offer their own top-ups and benefits for GIS recipients, and some programs use GIS eligibility as a fast way to qualify you for extras like drug coverage or housing support.

It is worth asking about these when you apply, and checking our provincial benefits overview and any home accessibility grants you might be eligible for. A little stacking of benefits can meaningfully ease the cost of care.

Staying compliant and avoiding scams

Keeping your GIS comes down to two habits: file your taxes every year, and keep your information current. Tell Service Canada promptly if your income changes a lot, if your marital status changes, or if you move or spend an extended time outside Canada, since these all affect your eligibility.

And please be careful with scams, because seniors are often targeted. Service Canada will never call, text, or email to demand payment, threaten you, or ask for your banking details. If a message feels wrong, it is. Hang up, do not click any links, and call the official number below to check.

Putting GIS to work for care

For lower-income seniors, GIS combined with OAS and CPP can be the difference between just getting by and being able to afford the right care. It is non-taxable, so it stretches further than it looks on paper.

A few ways to make the most of it:

• Stack it with OAS and the Canada Pension Plan, and check provincial benefits.
• Look at lower-cost options like senior apartments and subsidized housing, where GIS goes furthest.
• Compare real monthly fees in our guides and listings across Canada so you know what fits the budget.

Seeing every benefit side by side often reveals that more is possible than a family first feared.

Common questions about GIS

What is GIS, in plain terms? It is a monthly, non-taxable top-up to Old Age Security for seniors with a low income. The lower your other income, the more you receive.

How is GIS different from OAS and CPP? OAS is based on your age and years in Canada, CPP on what you contributed at work, and both are taxable. GIS is an income-tested top-up on OAS, and it is tax-free.

Is GIS taxable? No. Unlike OAS and CPP, GIS is non-taxable. You still report it, but the amount itself is not taxed.

Why did my GIS stop? The most common reason by far is a missed tax return. GIS renews from your taxes each year, so if a return is late or unfiled, payments pause until you file.

Can I work and still get GIS? Yes, within limits. There is an earnings exemption, so some employment and self-employment income does not count, though higher income gradually reduces the supplement.

Where to get help

You do not have to work this out alone, and you should not leave money on the table. For your own situation, Service Canada can confirm exactly what you qualify for.

• By phone: call Service Canada at 1-800-277-9914 (TTY 1-800-255-4786) for GIS and Old Age Security.
• Online: your My Service Canada Account is the fastest way to apply, check amounts, and update your details.
• Free tax help: community volunteer tax clinics can file your return each year so your GIS keeps renewing.
