The Guaranteed Income Supplement is one of the most important monthly benefits for low-income seniors in Canada. Many retirees rely on the Guaranteed Income Supplement to cover basic living costs alongside Old Age Security.
If you are wondering who is eligible for Guaranteed Income Supplement, how much the Guaranteed Income Supplement for a couple is, what income is used to calculate GIS in Canada, and how to apply for Guaranteed Income Supplement, this detailed guide covers everything based on official information from Government of Canada sources.
What Is the Guaranteed Income Supplement in Canada
The Guaranteed Income Supplement, often called GIS, is a non-taxable monthly benefit paid to low-income seniors who already receive Old Age Security.
The Guaranteed Income Supplement is designed to provide additional financial support to seniors who have little or no income other than OAS. Payments are reviewed and adjusted every year based on income reported in your tax return.
Who Is Eligible for Guaranteed Income Supplement
Understanding who is eligible for Guaranteed Income Supplement is the first step to receiving payments.
To qualify for the Guaranteed Income Supplement in Canada, you must:
- Be 65 years of age or older
- Be receiving Old Age Security
- Live in Canada
- Have a low annual income based on thresholds set by the government
Eligibility for Guaranteed Income Supplement depends heavily on your marital status and income level.
Income Limits for Guaranteed Income Supplement
Income thresholds change every year, but generally:
- Single seniors must have income below a set limit
- Couples must have a combined income below a higher threshold
The lower your income, the higher your Guaranteed Income Supplement payment.

How Much Is the Guaranteed Income Supplement for a Couple
One of the most searched questions is how much is the Guaranteed Income Supplement for a couple.
The Guaranteed Income Supplement for a couple depends on both partners’ income and whether both receive Old Age Security.
Maximum GIS Payment for Couples
For 2026, approximate maximum monthly amounts are:
- Couple where both receive OAS: up to around $650–$700 each per month
- Couple where one receives OAS and the other receives Allowance: slightly different rates apply
This means a couple could receive over $1,300 per month combined through the Guaranteed Income Supplement.
However, these are maximum amounts. The actual Guaranteed Income Supplement for a couple is reduced as income increases.
What Income Is Used to Calculate GIS in Canada
A key factor in determining your benefit is understanding what income is used to calculate GIS in Canada.
The Guaranteed Income Supplement is calculated based on your previous year’s income, as reported on your tax return.
Types of Income Included
The following types of income are used to calculate GIS:
- Employment income
- Pension income (including CPP)
- Investment income
- Rental income
Types of Income Not Included
Some benefits are excluded when calculating GIS:
- Old Age Security payments
- Guaranteed Income Supplement payments themselves
This is why filing your taxes every year is essential to continue receiving the correct amount.
How Guaranteed Income Supplement Payments Are Calculated
The Guaranteed Income Supplement works on a sliding scale.
- Lower income = higher GIS payment
- Higher income = reduced GIS payment
For every dollar of income above a certain level, your GIS benefit is gradually reduced.
This ensures that the Guaranteed Income Supplement targets those who need it most.
