GIS Eligibility and Income Cutoffs (2026)

The Guaranteed Income Supplement (GIS) is a tax-free monthly benefit for low-income Canadian seniors aged 65 and over who receive Old Age Security. Eligibility requires Canadian residency and an annual income below threshold amounts that vary by marital status and OAS receipt of a spouse. For Q1 2026, a single OAS recipient with income below $22,488 receives some GIS; the maximum monthly amount is $1,108.74. GIS is reduced by approximately $0.50 per dollar of non-OAS income above zero.

GIS eligibility requirements

• Age 65 or older.
• Receiving the Old Age Security pension.
• Canadian resident (legal status; not strictly the 40 years required for full OAS).
• Annual net income (excluding OAS itself and certain other items) below the cutoff for marital status.

Unlike OAS, GIS is income-tested annually. Eligibility and amount are recalculated each July based on the prior year’s tax return.

2026 GIS maximum amounts and income cutoffs

Income is calculated excluding OAS but including most other income: CPP, RRIF/RRSP withdrawals, employment income (with a $5,000 exemption plus 50% partial exemption between $5,000 and $15,000), interest, dividends, capital gains, and pension income. TFSA withdrawals do not count as income.

Worked example: single senior

Maria is 68, receives OAS, and has annual income of $12,000 from CPP. Her GIS calculation:

• Income for GIS: $12,000 (CPP)
• GIS reduction: roughly $0.50 per dollar of income, so $6,000 reduction annually = $500/month
• Maximum monthly GIS: $1,108.74
• Estimated GIS: $1,108.74 – $500 = $608.74/month

Combined with OAS ($743.05/month), Maria’s total monthly federal benefits are approximately $1,351.79 ($16,221/year), plus her CPP of $1,000/month for total income of $28,621/year.

Employment income exemption

To encourage seniors to remain in the workforce, the Income Tax Act exempts the first $5,000 of employment or self-employment income for GIS purposes, plus 50% of the next $10,000. A senior earning $15,000 from employment has effective GIS-counted employment income of $0 + 50% × $10,000 = $5,000 (the first $5,000 is fully exempt, the next $10,000 is half-exempt).

How GIS is calculated and paid

GIS is recalculated each July based on the prior calendar year’s tax return. Service Canada applies the formulas based on the income reported. GIS payments are made monthly, deposited together with OAS. The GIS amount can change July 1 each year based on income changes.

For seniors who experience a sudden income drop (e.g., spouse dies, employment ends), Service Canada can recalculate based on estimated current-year income through Form ISP-3025 (Statement of Income for the GIS for the current year). This avoids waiting until the next July recalculation.

Allowance and Allowance for the Survivor

The Allowance is for low-income Canadians aged 60-64 whose spouse receives OAS and GIS. The Allowance for the Survivor is for widowed Canadians aged 60-64 with low income. Both are means-tested similarly to GIS and end at age 65 when the recipient becomes eligible for OAS and possibly GIS.

Strategies to maximize GIS

Because GIS reduces at approximately 50% of income above the threshold, every dollar of income earned costs $0.50 of GIS. Strategies to preserve GIS:

• Withdraw from TFSA, not RRIF. TFSA withdrawals are not income for GIS; RRIF withdrawals are.
• Realize capital gains in non-GIS years (before 65 or after GIS phase-out).
• Contribute to spouse’s RRSP using spousal RRSP to keep retirement income lower in your own GIS-eligible years.
• Take advantage of employment income exemption ($5,000 fully exempt + 50% of next $10,000).

Application

GIS is generally automatic if the senior files annual tax returns. Service Canada uses tax return data to determine eligibility. Seniors who haven’t applied can submit Form ISP-3025 (or apply through My Service Canada Account). Eligibility can be retroactive up to 11 months from the application date.
