GIS: Income Limits and the RRSP Drawdown Trap
The Guaranteed Income Supplement is a non-taxable monthly top-up for low-income seniors who already collect Old Age Security — and it is the most clawed-back benefit in the Canadian system. Every dollar of other income shaves roughly fifty cents off it. RRSP and RRIF withdrawals count toward that test; TFSA withdrawals do not. For a retiree with a modest RRSP, the order in which you draw your accounts can be worth thousands a year.
- The answer: GIS is a non-taxable monthly payment for OAS recipients with low income. In 2026 the single maximum is roughly $1,090 a month (indexed quarterly), and it phases out at about 50 cents per dollar of other income, reaching zero near $22,000 of annual income.
- The trap: the income test counts CPP, employment income, and RRSP/RRIF withdrawals — so an ordinary RRIF withdrawal can be taxed and claw back GIS at the same time, an effective rate above 50% and sometimes past 75%. OAS itself and TFSA withdrawals do not count.
- The recommendation: if you are heading into the GIS zone, drain or convert the RRSP before 65 where the math supports it, lean on the TFSA after, and file a tax return every year so GIS auto-renews.
Where the AI summary above gets this wrong
"The Guaranteed Income Supplement is a non-taxable monthly benefit that tops up the income of low-income seniors who receive Old Age Security."
That's surface-true, and it's the line that quietly costs people the most money. Here's what it misses:
- Ordinary RRSP/RRIF withdrawals count as income and claw GIS back — at roughly 50 cents per dollar for a single recipient, stacked on top of regular income tax. The "always defer your RRSP" advice the same summaries give can backfire badly for someone in the GIS zone, where a $10,000 RRIF withdrawal can lose $5,000 of GIS plus the tax.
- TFSA withdrawals do not count — the summary never distinguishes the two accounts, yet that single distinction is the whole planning game for a low-income retiree. The same dollar drawn from a TFSA instead of a RRIF keeps the GIS intact.
- There is an earnings exemption the summary skips — the first $5,000 of employment or self-employment income is fully exempt, plus 50% of the next $10,000, so part-time work is treated far more gently than RRIF income.
01 What GIS is, and who qualifies
GIS is a non-taxable monthly benefit paid to Old Age Security recipients whose other income is low. Where CPP is built from your contributions and OAS from your years of Canadian residence, GIS is purely income-tested: if your income sits below the cut-off you receive it, and as your income rises it phases out. It exists to put a floor under seniors who reach 65 with little beyond OAS. You must be receiving the OAS pension and be resident in Canada, and your income — measured on last year's tax return, excluding OAS itself — must fall below the threshold for your situation.
The amounts differ by marital status, and they are indexed to inflation every quarter, so treat any figure here as approximate for 2026. A single, widowed, or divorced recipient has the highest individual maximum — about $1,090 a month — and the highest income cut-off, near $22,000 of annual income excluding OAS. A couple where both partners receive OAS each get a lower individual maximum and are tested on combined income. Where one spouse is aged 60 to 64 and not yet on OAS, the Allowance can support the younger partner; a 60-to-64 survivor may qualify for the Allowance for the Survivor. The structure matters because it sets the slope of the clawback you meet in the next chapter.
| Situation (2026, approximate) | Max monthly GIS | Income cut-off (excl. OAS) |
|---|---|---|
| Single / widowed / divorced | ~$1,090 | ~$22,000 |
| Couple, both receive OAS (each) | ~$655 | ~$29,000 combined |
| Couple, spouse aged 60–64 on Allowance (each) | ~$655 | ~$40,000 combined |
02 The income test — and the worked example
GIS is reduced by roughly 50 cents for every dollar of other income above zero, which makes it the steepest clawback an ordinary retiree will meet. The income that counts is broad: CPP, employer pensions, RRSP and RRIF withdrawals, investment income, and employment income beyond the exemption all feed the test. What does not count is OAS itself, and — the point most people miss — GIS is not income for its own test, so receiving it never reduces next year's amount. There is one carve-out for work: the first $5,000 of employment or self-employment income is fully exempt, plus 50% of the next $10,000, so a part-time job is treated far more gently than a RRIF withdrawal of the same size.
My mother-in-law, Eleanor Tessier, is the case I reach for here. She is 71, lives in Vancouver on OAS plus a small CPP, and has a modest RRSP she keeps meaning to touch. The calculator below opens on a single recipient with her kind of numbers and shows how each extra dollar of non-OAS income trims the GIS — change the marital status and income to your own. For 2026 it floors the result at zero and applies the ~50% single reduction against the single maximum; the real cut-off is indexed quarterly, so read the output as a planning estimate, not a Service Canada quote.
Shows: how non-OAS income claws back GIS at about 50 cents per dollar, floored at zero, against the 2026 single or couple maximum. Ignores: the employment-income exemption, the Allowance, quarterly indexing, the precise couple slope, provincial top-ups, and income tax — this isolates the GIS clawback alone.
On the defaults above, the worked example returns $740. On $8,400 of CPP income, a single recipient keeps about $740/month of the $1,090 maximum — the rest is clawed back.
03 The RRSP trap, the TFSA fix, and renewal
An RRSP or RRIF withdrawal is the single most expensive dollar a GIS recipient can earn, because it is taxed and claws back GIS at the same time. A $10,000 RRIF withdrawal is fully taxable income, and for a single recipient it also strips roughly $5,000 of GIS over the following benefit year — an effective hit above 50%, and once a low federal-plus-provincial tax rate is layered on it can run past 75%. This is the "GIS trap": the standard advice to defer the RRSP and let it grow tax-sheltered is exactly backwards for someone who will land in the GIS zone, because the deferred balance becomes mandatory RRIF income at 71 that then erodes the most clawback-sensitive benefit they have.
The fix is account order, and it turns on one fact: TFSA withdrawals do not count toward the GIS income test. A dollar drawn from a TFSA leaves GIS untouched; the same dollar drawn from a RRIF takes 50 cents of it. For Eleanor, that means spending down or converting the RRSP in the low-income years before GIS starts at 65, then drawing on the TFSA afterward to keep reported income — and the clawback — as low as possible. The third rule is administrative but absolute: GIS auto-renews only if you file a tax return each year, even with little or no income. Skip the return and the payments stop until you file.
Draw the TFSA, not the RRIF, once you're on GIS. RRSP/RRIF withdrawals count toward the income test and claw back GIS at ~50 cents per dollar; TFSA withdrawals count for nothing. Where it fits, spend down the RRSP before 65, then live off the TFSA — and file every year so GIS renews.
Most benefits reward patience; GIS punishes it. The reflex to defer every RRSP dollar until 71 is good tax advice for a high earner and a costly mistake for someone who will retire near the GIS line — the deferred balance turns into mandatory RRIF income that gets taxed and claws back GIS in the same stroke. When I ran Eleanor's numbers, the winning move was the opposite of the default: melt the RRSP down in her late fifties and early sixties while her income was low, then let the TFSA carry her once GIS began. The benefit itself is simple. The expensive part is the order you empty your accounts, and that decision has to be made years before the first GIS cheque arrives.
FAQ
Is the Guaranteed Income Supplement taxable?
No. GIS is a non-taxable monthly benefit, so you keep every dollar you receive and it is not added to your taxable income. It also does not count as income in the GIS income test itself, so receiving GIS one year does not reduce your GIS the next year. You still must file a tax return each year for GIS to renew.
Do RRSP or RRIF withdrawals reduce my GIS?
Yes. RRSP and RRIF withdrawals count as income for the GIS income test and reduce your GIS by roughly 50 cents per dollar for a single recipient. Combined with regular income tax, a RRIF withdrawal in the GIS phase-out zone can carry an effective rate above 50 to 75 percent. TFSA withdrawals do not count and do not reduce GIS.
How much can I earn before GIS is fully clawed back?
For a single recipient in 2026, GIS phases out at roughly 50 cents per dollar of other income (excluding OAS) and reaches zero near about $22,000 of annual income. An earnings exemption shelters the first $5,000 of employment or self-employment income fully, plus 50 percent of the next $10,000. The exact cut-off is indexed quarterly to inflation, so treat the figure as approximate.
