The Guaranteed Income Supplement (GIS) is a monthly, non-taxable benefit paid to low-income Canadian seniors who receive OAS. It is income-tested and reduces as your other income increases.
How the GIS Works
GIS eligibility is based on your net income in the previous calendar year, excluding OAS. In 2025, single seniors can receive GIS if their income is below approximately $22,056. The GIS is reduced by 50 cents for every dollar of other income. A spike in income — such as a large RRIF withdrawal — can reduce or eliminate GIS for the following year.
Why It Matters in Retirement
The GIS planning trap affects a broader group than expected. A well-designed drawdown strategy coordinating RRIF withdrawals, TFSA use, and CPP timing can preserve GIS eligibility for those near the threshold.
