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. For planning examples, see what happens if you exceed the GIS income limit and how much can I earn on GIS before clawback.
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.
GIS and CPP deferral: a key trade-off
Deferring CPP to 70 increases your CPP by 42% but may reduce your GIS if CPP income pushes you over the GIS income threshold. For very low-income seniors who expect to receive significant GIS, starting CPP at 65 may actually preserve more total income:
| Scenario | CPP at 65 | CPP at 70 | Difference |
|---|---|---|---|
| Low-income senior, CPP ~$400/month | CPP: $400; GIS ~$1,000/month | CPP: $568; GIS ~$916/month | Total: ~$1,400 vs ~$1,484 — modest gain |
| Low-income senior, CPP ~$800/month | CPP: $800; GIS ~$687/month | CPP: $1,136; GIS ~$519/month | Total: ~$1,487 vs ~$1,655 — defer wins |
The break-even analysis for GIS recipients is more complex than for those above the GIS threshold — the GIS offset partially neutralizes the CPP deferral bonus. If GIS preservation matters more than lifetime CPP maximization, model both scenarios before choosing your CPP start date.
