By GIS in 2026: Amounts, the 50-Cent Clawback and Why a Small RRSP Can Cost You Thousands
The Guaranteed Income Supplement (GIS) is the largest single top-up available to lower-income seniors in Canada — and the easiest to lose by accident. For October to December 2026, GIS pays up to $1,138.90 a month, tax-free, to a single senior whose other income is under $23,112. But GIS is reduced by roughly 50 cents for every $1 of income you report. That one rule means a small RRSP withdrawal can quietly cost you thousands of dollars. This guide gives the current amounts, the income limits, and the planning moves that protect the benefit.
GIS amounts: October to December 2026
| Your situation | Maximum GIS per month | Annual income must be below |
|---|---|---|
| Single, widowed or divorced | $1,138.90 | $23,112 |
| Spouse or partner receives the full OAS pension | $685.56 each | $30,528 (combined) |
| Spouse or partner receives the Allowance | $685.56 | $42,768 (combined) |
| Spouse or partner receives neither OAS nor the Allowance | $1,138.90 | $55,392 (combined) |
Source: Service Canada’s Old Age Security payment amounts for October to December 2026, up 1.4% from the previous quarter (the single maximum was $1,123.17 from July to September 2026). GIS is indexed every January, April, July and October and never falls with indexation. It is paid with your OAS pension — the maximum OAS pension itself is $762.50 a month at ages 65 to 74 and $838.75 at 75 and older — on the dates in our OAS payment dates guide. “Income” here means your net income from the previous tax year, not counting the OAS pension itself, and with an employment exemption described below.
How the 50-cent clawback works
GIS is not an all-or-nothing benefit. As your other income rises, your payment falls — by about $0.50 for every $1 of income in the main range, and by more in some low-income ranges where the GIS top-up is also being reduced. Service Canada recalculates your amount every July, using the tax return you filed that spring. So the income you earn in 2026 sets your GIS from July 2027 to June 2028. Two kinds of income are treated specially:
- Employment and self-employment income: the first $5,000 is fully exempt, and 50% of the next $10,000 (from $5,000 to $15,000) is also exempt. A part-time job is therefore cheaper, in GIS terms, than the same amount of investment income.
- OAS pension income: your OAS pension itself does not reduce your GIS. CPP/QPP benefits, RRSP and RRIF withdrawals, investment income and capital gains do.
Worked example: the $5,000 RRSP withdrawal that costs $2,500
Illustration only, using the general 50% reduction rate. Margaret, 68 and single, receives the OAS pension, a small CPP pension, and GIS. In December 2026 she withdraws $5,000 from her RRSP for a roof repair.
| Effect | Amount |
|---|---|
| RRSP withdrawal (counts as income in 2026) | +$5,000 income |
| GIS reduction from July 2027 (about 50%) | About -$2,500 over the following year (about -$208 a month) |
| Income tax on the withdrawal (if taxable income is high enough) | $0 to about $1,000, depending on her total income and credits |
| Same $5,000 taken from a TFSA instead | $0 GIS reduction — TFSA withdrawals are not income |
The same logic scales up. A $20,000 RRIF withdrawal can erase roughly $10,000 of GIS over the next benefit year — an effective cost far above the tax bracket shown on the withdrawal. This is the opposite problem from the OAS clawback, which affects higher-income seniors: GIS losses hit people with the least income, at a 50% rate, starting from the first dollars.
Five moves that protect your GIS
- Spend TFSA money before RRSP money. TFSA withdrawals never appear as income, so they never reduce GIS. For likely GIS recipients, drawing the RRSP down before age 65 — or converting income timing around it — is often worth more than the tax deduction was.
- Time RRSP withdrawals before OAS/GIS starts. Withdrawals between retirement and age 65 do not touch GIS, because GIS has not started. Melting down a small RRSP in your early 60s can preserve years of full GIS later.
- Use the pension income split. Couples can split eligible pension income (such as RRIF income after 65) on their tax returns. Moving income from the higher-income spouse to the lower-income one can raise the couple’s combined GIS.
- Watch capital gains and one-off income. Selling an asset, cashing a large GIC, or taking a one-time payment in one year reduces GIS for a full 12 months starting the next July. Spreading gains across two tax years can halve the damage.
- File your tax return every year, on time. GIS renewal is automatic only if you file. A late return is the most common reason payments stop in July — and the fix (filing, then waiting for reinstatement) takes months. Check all federal payment timing in our benefit payment dates table.
Your CPP timing decision also feeds this calculation, because CPP is income that reduces GIS — one more reason to run the numbers in our CPP at 60 vs 65 vs 70 guide before you apply.
How to apply, and what to do if your income drops
Many seniors are enrolled in GIS automatically when they are approved for the OAS pension, based on the income information the government already has. If that did not happen for you — for example, if you delayed OAS, recently immigrated, or your income fell after you started OAS — you apply yourself, either in My Service Canada Account or with paper Form ISP-3025. Apply as soon as you apply for OAS: GIS cannot be paid retroactively for more than 11 months, so a late application is money permanently lost, not merely delayed.
The July recalculation cuts both ways, and this is the part most guides leave out. If your income drops partway through the year — you retire, stop working, or a pension ends — you do not have to wait for next July. Contact Service Canada and ask for your GIS to be based on an estimate of your current-year income instead of last year’s tax return. Retirement and the loss of a regular income source are exactly the situations this estimate option exists for. Without it, a senior who retired in September can be stuck with a GIS amount calculated on a full working salary for up to ten more months, even though the salary is gone.
The reverse also applies. If you receive a one-time payment — a severance amount, a large RRSP withdrawal to clear a debt, or a capital gain — in a single year, that one year of high income reduces your GIS for the entire following benefit year. Where you have any choice about timing, splitting a large withdrawal or a property sale across two calendar years, or completing it before your OAS and GIS begin, usually costs far less than taking it all in one GIS year.
Finally, keep Service Canada informed directly. A change of address, marital status, or a spouse’s death changes your payment category, and benefits paid at the wrong rate create an overpayment debt that is recovered from future payments. A short call when your situation changes is much cheaper than a recovery letter a year later.
Common mistakes
- Assuming GIS is automatic forever. It renews only when you file a tax return each year. No return, no July payment.
- Taking a lump-sum RRSP withdrawal in a GIS year without doing the 50% math. The withdrawal is taxed and cuts next year’s GIS — a double cost most people only discover a year later.
- Forgetting to report a change in marital status. Marrying, separating, or a spouse’s death changes your rate category. Report it promptly: overpayments must be repaid, and underpayments are money lost.
- Staying outside Canada too long. GIS stops after 6 months outside Canada, unlike the OAS pension itself, which can be paid abroad if you meet the residency rules.
- Not applying because you were not enrolled automatically. Many seniors are auto-enrolled with OAS, but not everyone. If you receive OAS and have low income and no GIS, apply through My Service Canada Account or with Form ISP-3025.
Frequently asked questions
How much GIS can I get in 2026?
For October to December 2026, the maximum is $1,138.90 a month if you are single, widowed or divorced, and $685.56 a month each for a couple where both partners receive the full OAS pension. Your actual amount depends on your previous year’s income and falls as income rises, ending completely at $23,112 of income for a single person.
Is GIS taxable?
No. GIS is a tax-free benefit. You receive a T4A(OAS) slip showing it, but the amount is not included in your taxable income — and your OAS pension itself does not count as income for the GIS calculation.
How much does GIS fall for each $1 I earn?
About 50 cents per $1 of income in the main range, and effectively more in some ranges where the low-income top-up is also reduced. Employment income gets special treatment: the first $5,000 is exempt, and half of the next $10,000 is exempt.
Does an RRSP or RRIF withdrawal reduce my GIS?
Yes. RRSP and RRIF withdrawals are income. They reduce your GIS starting the following July, by roughly 50% of the withdrawal amount over the next benefit year. TFSA withdrawals do not reduce GIS at all.
When is GIS recalculated?
Every July, using the income on the tax return you filed that spring. The October to December 2026 amounts rose 1.4% with inflation indexation; the income test behind them is your 2025 income for payments from July 2026 to June 2027.
Can I get GIS if I still work part-time?
Yes, if your total income is under the limit for your situation. The employment exemption — $5,000 fully exempt plus 50% of the next $10,000 — means a modest part-time income reduces GIS by much less than the same amount of pension or investment income.
Bottom line: GIS can add up to $1,138.90 a month in tax-free income in late 2026, but every dollar of reported income costs you about 50 cents of it. File every year, prefer TFSA withdrawals over RRSP withdrawals once GIS starts, and do the clawback math before any lump-sum move. This article is general information, not financial advice.
