Frequently Asked Questions
What is the Guaranteed Income Supplement?
The GIS is a monthly non-taxable benefit for low-income OAS pensioners aged 65+. It is based on your income (excluding OAS) and marital status. You must reapply or have your tax return assessed each year.
How is GIS reduced?
GIS is reduced by approximately 50 cents for every dollar of income you receive above the exemption threshold (excluding OAS). Employment income has a partial exemption of up to $5,000.
Is GIS taxable?
No. GIS payments are non-taxable and do not need to be reported as income on your tax return. However, your other income determines how much GIS you receive.
