A Deep Dive into the Guaranteed Income Supplement (GIS)
What is the Guaranteed Income Supplement (GIS)?
The Guaranteed Income Supplement (GIS) is a non-taxable monthly payment from the Canadian government designed for low-income Old Age Security (OAS) pensioners. The primary purpose of the GIS is to provide additional financial support to seniors to help them meet their basic needs. Understanding **what income is used to calculate GIS in Canada** is crucial for proper retirement planning.
This benefit is intended for residents of Canada who are 65 or older and have an income below specific thresholds set by the government. Unlike the Canada Pension Plan (CPP), the GIS is not tied to your employment history; it is purely income-tested. One common misconception is that GIS is the same as OAS. In reality, GIS is a separate benefit that *supplements* the OAS pension for those with low income.
GIS Formula and Mathematical Explanation
The calculation for the GIS is designed to be a sliding scale: the higher your other income, the lower your GIS benefit. The core principle is that your GIS is reduced by a set amount for every dollar of countable income you (and your spouse, if applicable) earn. The basic formula is:
Estimated GIS = Maximum GIS Benefit – (Countable Income × Reduction Rate)
Typically, the GIS is reduced by $0.50 for every $1 of monthly income. For couples, the calculation can be more complex. The first step is always to determine your total countable income, which is a key part of figuring out **what income is used to calculate GIS in Canada**.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Countable Income | Your (and your spouse’s) total annual income from various sources, excluding OAS/GIS. | CAD ($) | $0 – ~$54,000 |
| Maximum GIS Benefit | The highest possible monthly GIS payment, which depends on your marital status. | CAD ($) | ~$650 – ~$1,100 per month |
| Reduction Rate | The rate at which the GIS benefit decreases as income increases. | Factor | Generally 0.5 (or 50%) |
This table explains the variables involved in the GIS calculation.
Practical Examples
Example 1: Single Pensioner
Meet Robert, a single, 68-year-old pensioner. His only income besides OAS is a $9,000 annual pension from his former employer.
- Inputs: Marital Status = Single, Annual Income = $9,000.
- Calculation: The GIS calculation shows that Robert’s income reduces his benefit. Based on current rates, his GIS is not eliminated but is significantly reduced from the maximum.
- Financial Interpretation: Robert is eligible for a partial GIS payment each month, which substantially supplements his OAS and small pension, helping him cover living expenses more comfortably. Understanding **what income is used to calculate GIS in Canada** allowed him to anticipate this supplemental income.
Example 2: Couple where Spouse Receives OAS
Consider Maria (66) and David (67). Both receive the OAS pension. Their combined annual income from CPP and a small RRSP withdrawal is $22,000.
- Inputs: Marital Status = Spouse receives OAS, Your Income = $12,000, Spouse’s Income = $10,000.
- Calculation: Their combined income of $22,000 is used. Each of them receives a GIS payment, calculated based on their shared income against the couple’s threshold.
- Financial Interpretation: Because their combined income is below the cutoff for a couple, they each receive a monthly GIS payment. This demonstrates how the GIS system supports couples based on their joint financial situation.

Key Factors That Affect GIS Results
The question of **what income is used to calculate GIS in Canada** involves several components. Here are six key factors:
- Marital Status: Being single, or having a spouse who does or does not receive OAS, dramatically changes the maximum benefit and the income cut-off levels.
- CPP or QPP Benefits: Payments from the Canada Pension Plan or Quebec Pension Plan are considered countable income and will directly reduce your GIS amount.
- Private Pension Income: Income from workplace pensions, superannuation, or foreign pensions is included in the calculation. You can find more details on our page about pension income and GIS.
- RRSP/RRIF Withdrawals: Money taken out of a Registered Retirement Savings Plan (RRSP) or a Registered Retirement Income Fund (RRIF) is taxable income and therefore counts against your GIS entitlement for the following year.
- Employment Income: While there is a small earnings exemption, most income from employment or self-employment will reduce your GIS. This is a critical aspect of **what income is used to calculate GIS in Canada**.
- Investment Income: Interest, dividends, and capital gains from non-registered investments are also considered countable income.
Frequently Asked Questions (FAQ)
No, your OAS pension payment is NOT included in the income calculation for GIS. The GIS is a supplement to your OAS.
No. Once you are approved for GIS, your entitlement is automatically reviewed each year when you file your income taxes. This is why it is vital to file your taxes on time every year. Explore our tax filing guide for seniors.
If you or your spouse retire or experience a significant loss of pension income, you can request that Service Canada calculate your GIS based on an *estimate* of your current year’s income instead of last year’s. This is an important option when considering **what income is used to calculate GIS in Canada**.
No, the Guaranteed Income Supplement is a non-taxable benefit. You do not have to pay income tax on any GIS payments you receive.
Generally, GIS payments are only made for up to six months if you are outside of Canada. After that, payments are suspended until you return to live in the country.
Besides OAS and GIS payments, other exemptions include the first $5,000 of employment income and 50% of the next $10,000. For more on this, see our GIS income exemptions page.
