Is the Guaranteed Income Supplement (GIS) taxable?

No. Unlike CPP and OAS, the Guaranteed Income Supplement (GIS) is completely tax-free income. You do not pay federal or provincial income tax on it, but you must still report it on your tax return.

What is the maximum income to qualify for GIS in 2026?

The income limit depends on your marital status. For single seniors, the individual income cut-off is roughly $21,624 (excluding OAS). For couples where both receive OAS, the combined limit is higher.

Does CPP reduce your GIS payments?

Yes. GIS is strictly income-tested. For every $1 you receive from other income sources like CPP, private pensions, or RRSP withdrawals, your GIS benefit is reduced by 50 cents ($0.50).
