Guaranteed Income Supplement (GIS) Guide
The Guaranteed Income Supplement (GIS) is a monthly benefit that provides additional financial support to low-income seniors who already receive Old Age Security (OAS). For many eligible Canadians, GIS plays an important role in helping cover everyday living expenses during retirement.
Unlike Old Age Security, GIS is income-tested. This means your eligibility and payment amount depend largely on your annual income and household situation. Understanding how the program works can help you determine whether you may qualify and how much assistance you could receive.
What Is the Guaranteed Income Supplement (GIS)?
The Guaranteed Income Supplement is a federal benefit administered by Service Canada. It is designed to provide additional monthly income to eligible seniors who receive Old Age Security and have limited income during retirement.
Unlike CPP or OAS, GIS is not based on employment history or years of contributions. Instead, it is primarily determined by your annual income and marital status.
Who Can Receive GIS?
To qualify for the Guaranteed Income Supplement, you must generally receive Old Age Security and meet the income requirements established by the Government of Canada. Eligibility is reassessed each year using information from your income tax return.
| Requirement | Description |
|---|---|
| Age | Generally 65 or older. |
| Receiving OAS | Required in most situations. |
| Income | Must fall below the applicable annual threshold. |
| Residence | Must satisfy applicable residency requirements. |
How Is GIS Different from OAS?
Although the Guaranteed Income Supplement and Old Age Security are closely connected, they are separate programs with different eligibility rules and payment calculations.
| Feature | Old Age Security (OAS) | Guaranteed Income Supplement (GIS) |
|---|---|---|
| Main purpose | Basic retirement pension. | Additional support for low-income seniors. |
| Based on income? | No (except Recovery Tax). | Yes. |
| Requires OAS? | No. | Generally yes. |
| Taxable? | Yes. | No. |
How Is GIS Calculated?
Your Guaranteed Income Supplement payment depends on several factors, including your annual income, marital status and whether your spouse or common-law partner also receives government retirement benefits.
The Government of Canada reviews payment rates regularly, and your benefit may change if your income changes from one year to the next.
| Factor | Affects GIS? |
|---|---|
| Annual income | Yes |
| Marital status | Yes |
| Receiving OAS | Yes |
| Employment history | No |
| CPP contributions | No |
Is the Guaranteed Income Supplement Taxable?
No. GIS payments are generally tax-free. Although they do not need to be included as taxable income, you should still file your annual income tax return because Service Canada uses your reported income to determine your ongoing eligibility.
Failing to file your tax return on time could delay or interrupt your Guaranteed Income Supplement payments.
GIS Income Limits
Eligibility for the Guaranteed Income Supplement depends largely on your annual income. The Government of Canada reviews income thresholds regularly, and your eligibility may change if your financial situation changes from one year to the next.
Because GIS is income-tested, lower-income seniors generally qualify for higher monthly payments, while increasing income may reduce the amount received.
| Income Situation | Possible GIS Outcome |
|---|---|
| Very low income | May qualify for the maximum GIS payment. |
| Moderate income | May qualify for a partial GIS payment. |
| Income above the applicable threshold | May not qualify for GIS. |
How Much Can You Receive?
The amount of your Guaranteed Income Supplement depends on your annual income, marital status and whether your spouse or common-law partner receives Old Age Security, GIS or other retirement benefits.
Maximum payment rates are reviewed by the Government of Canada on a regular basis and may change over time.
| Situation | Possible Payment |
|---|---|
| Single senior with very low income | May qualify for the maximum GIS amount. |
| Couple with low combined income | May qualify for partial or full GIS depending on eligibility. |
| Higher household income | Reduced GIS or no eligibility. |
Does GIS Need to Be Renewed Every Year?
In most cases, you do not need to submit a new GIS application every year if you continue to meet the eligibility requirements and file your annual income tax return on time.
Service Canada generally reviews your income information each year using data provided by the Canada Revenue Agency to determine your continued eligibility and payment amount.
| Situation | Annual Review |
|---|---|
| Income tax return filed | Eligibility is generally reviewed automatically. |
| Income tax return not filed | GIS payments may be delayed or interrupted. |
| Major income changes | Your GIS payment may change after review. |
Single vs. Married Eligibility
Your marital status is an important factor when determining GIS eligibility. The Government of Canada uses different income thresholds depending on whether you are single, married or living in a common-law relationship.
If your marital status changes, you should notify Service Canada promptly because your benefit amount may need to be recalculated.
| Household Situation | Income Considered |
|---|---|
| Single | Your annual income. |
| Married or common-law | Combined household income is generally considered. |
| Change in marital status | May affect future GIS payments. |
How Income Affects Your GIS Payment
Because GIS is designed to support lower-income seniors, increases in annual income may reduce your monthly benefit. Income from pensions, employment and certain investments may affect your eligibility depending on the applicable program rules.
Reporting your income accurately each year helps ensure that your GIS payments are calculated correctly and reduces the risk of overpayments or underpayments.
| Income Source | May Affect GIS? |
|---|---|
| CPP retirement pension | Yes |
| Employer pension | Yes |
| Employment income | Yes (subject to applicable GIS rules). |
| Investment income | Yes |
| Other retirement income | Yes |
How to Check Your GIS Eligibility
If you receive Old Age Security or expect to become eligible soon, you can review your Guaranteed Income Supplement eligibility through My Service Canada Account (MSCA). The online portal allows eligible seniors to review benefit information, update personal details and manage their retirement benefits.
Reviewing your information regularly helps ensure that your income, marital status and payment details remain accurate for future GIS assessments.
| Service | Available Through MSCA |
|---|---|
| View GIS information | Yes |
| Review OAS benefits | Yes |
| Update personal information | Yes |
| Manage direct deposit | Yes |
What Happens If Your Income Changes?
Because GIS is income-tested, changes to your annual income may increase or reduce your monthly benefit. Service Canada normally reviews your income every year using information provided through your income tax return.
If your financial circumstances change significantly, you should contact Service Canada to determine whether your GIS payments may be affected.
Can You Receive GIS with Other Retirement Benefits?
Yes. The Guaranteed Income Supplement is designed to work alongside Old Age Security and may also be received by eligible seniors who receive Canada Pension Plan benefits or other retirement income.
However, because GIS is income-tested, other sources of retirement income may affect the amount you receive.
| Benefit | Can Be Received with GIS? |
|---|---|
| Old Age Security (OAS) | Yes (generally required). |
| Canada Pension Plan (CPP) | Yes. |
| Employer Pension | Yes, but may affect payment amount. |
| RRIF Withdrawals | Yes, but may affect eligibility. |
| Investment Income | Yes, but may affect payment calculations. |
How to Maintain Your GIS Benefits
Receiving GIS is not simply a matter of qualifying once. To continue receiving payments, you should keep your personal information current and file your income tax return every year, even if you have little or no taxable income.
Most ongoing eligibility reviews are completed automatically using information from the Canada Revenue Agency.
- File your income tax return every year.

Planning Retirement with GIS
The Guaranteed Income Supplement can represent an important portion of retirement income for eligible low-income seniors. Understanding how GIS works together with OAS, CPP and other retirement income sources can help you build a more stable financial plan.
If you expect your retirement income to change, reviewing your benefit eligibility each year can help you understand how future payments may be affected.
| Retirement Income Source | Relationship with GIS |
|---|---|
| Old Age Security (OAS) | Generally required to receive GIS. |
| Canada Pension Plan (CPP) | Can be received together, but affects income calculations. |
| Employer Pension | May reduce GIS eligibility depending on income. |
| Personal Savings | May influence overall retirement planning. |
| Investment Income | May affect annual income calculations. |
