The Guaranteed Income Supplement is one of the most generous benefits in Canada — and one of the most under-applied. Tens of thousands of eligible seniors receive no GIS simply because they forgot to apply or assumed they did not qualify.
Maximum GIS Amounts by Marital Status (2026)
| Situation | Monthly Maximum | Annual Maximum |
|---|---|---|
| Single, widowed, or divorced | $1,086.88 | $13,043 |
| Couple — both receiving OAS | $654.23 each | $7,851 each |
| Couple — only one receives OAS | $1,023.88 (OAS recipient) | $12,287 |
GIS is paid on the same schedule as OAS — the third-to-last business day of each month.
GIS + OAS Combined Maximum (2026)
For a low-income single senior receiving both OAS and the maximum GIS:
| Benefit | Monthly |
|---|---|
| OAS (ages 65–74) | $727.67 |
| Maximum GIS (single) | $1,086.88 |
| Combined maximum | $1,814.55/month |
| Annual combined | $21,775/year |
For couples where both receive the maximum OAS and GIS:
| Benefit | Per Person | Combined |
|---|---|---|
| OAS | $727.67 | $1,455.34 |
| GIS | $654.23 | $1,308.46 |
| Total per month | $1,381.90 | $2,763.80 |
Income Thresholds: How Much Can You Earn?
GIS is reduced by 50 cents for every dollar of income you earn beyond a small exemption.
Income Cutoffs to Receive Any GIS (2026)
| Situation | Maximum Annual Income (excluding OAS) |
|---|---|
| Single / widowed / divorced | ~$22,000 |
| Couple — both receive OAS | ~$29,136 combined |
| Couple — only one receives OAS | ~$52,416 combined |
What counts as income for GIS purposes:
- Employment income (with a $5,000 exemption)
- RRSP/RRIF withdrawals
- Pension income (CPP, private pensions, foreign pensions)
- Investment income (interest, dividends, capital gains)
- Rental income
What does NOT count:
- OAS itself
- GIS payments
- TFSA withdrawals
- Most one-time government payments
Employment Income Exemption
The first $5,000 of employment income is completely exempt when calculating GIS. On income between $5,000 and $15,000, only 50% counts — this allows low-income seniors who still work part-time to retain significant GIS benefits.
| Employment Income | Amount Counted Toward GIS Limit |
|---|---|
| $0–$5,000 | $0 (full exemption) |
| $5,001–$15,000 | 50% of this amount |
| Over $15,000 | 100% of excess |
GIS Phase-Out Rate
GIS is reduced by 50 cents for every dollar of income (after exemptions). This means:
| Income Above Exemptions | GIS Reduction |
|---|---|
| $1,000 | $500 less GIS |
| $5,000 | $2,500 less GIS |
| $10,000 | $5,000 less GIS |
The effective marginal tax rate for GIS recipients who earn income can be very high — combining GIS reduction (50%) with CPP (0%), income tax (~20–25%), and possible provincial benefit reductions can mean keeping only 25–30 cents of each dollar earned.
How to Apply for GIS
Unlike OAS, GIS is not automatically paid — you must apply.
When to apply:
- Apply along with your OAS application (form ISP-3026)
- If already receiving OAS, apply separately through Service Canada
- Re-qualify automatically each year by filing your taxes
If you miss GIS for a period you were eligible, Service Canada can retroactively pay up to 11 months of missed GIS payments once your application is approved.
Does TFSA Income Affect GIS?
No. Withdrawals from a TFSA do not count as income for GIS purposes. This is one of the most powerful financial planning strategies for lower-income seniors:
- Hold RRSP/RRIF assets in TFSA where possible before retirement
- Draw from TFSA in retirement rather than RRSP/RRIF
- TFSA withdrawals preserve full GIS entitlement
- RRSP/RRIF withdrawals reduce GIS dollar-for-dollar (after the 50% taper)
Example: A senior with $50,000 in an RRSP converts to TFSA during a low-income year before age 65 — then draws $10,000/year in retirement from TFSA instead of RRSP. Their GIS is preserved vs. being reduced by ~$5,000/year.
Allowance and Allowance for Survivor (Related Programs)
Two additional programs top up income for low-income Canadians who are not yet 65 but are connected to an OAS/GIS recipient:
| Benefit | Who Qualifies | Monthly Maximum |
|---|---|---|
| Allowance | Ages 60–64, low income, spouse receives OAS & GIS | $1,381.90 |
| Allowance for Survivor | Ages 60–64, widow/widower, low income | $1,647.34 |
These benefits end on the earlier of age 65 (when OAS/GIS begins) or when income exceeds the applicable threshold.
