Guaranteed Income Supplement
Do you qualify for the GIS?
The GIS tops up Old Age Security for lower-income seniors — and it's tax-free. See what you might receive and the income ceiling that ends it.
The Guaranteed Income Supplement is a monthly, tax-free top-up to OAS for lower-income seniors. The income test excludes OAS and TFSA withdrawals but counts CPP, RRIF and employment income — so where your retirement income comes from can affect your eligibility. Enter your income to estimate your GIS.
CPP + RRIF + other taxable income, excluding OAS and TFSA.
First $5,000 is fully exempt, plus 50% of the next $10,000.
Drawing more taxable income (e.g. from a RRIF) reduces GIS — sourcing from a TFSA instead preserves it.
Estimate for education, not advice. Based on 2026 GIS figures (single-rate benefit); couple amounts vary with your spouse's OAS/Allowance status. Deliberately minimizing taxable income has real trade-offs — confirm with Service Canada.
