Guaranteed Income Supplement: eligibility

The Guaranteed Income Supplement (GIS) is almost always presented as a table of thresholds: if your income is below a given amount, you qualify. That’s accurate, but it’s half the story. The GIS is also a planning lever: because it drops by roughly 50 cents per dollar of income, and because what counts as income depends on which account the money comes from, the timing and order of your withdrawals can decide your eligibility. Here’s how the GIS works, what counts as income, and why an RRSP withdrawal and a TFSA withdrawal don’t have the same effect.

Who qualifies for the Guaranteed Income Supplement

The GIS tops up the Old Age Security (OAS) pension. To qualify, you must:

• Be 65 or older and receiving the OAS;
• Live in Canada;
• Have income below the threshold for your marital status;
• Not be under a sponsorship agreement (with some exceptions).

The GIS is a tax-free monthly payment. In most cases, Service Canada enrolls you automatically when you become eligible for the OAS; otherwise, you have to apply.

What is the maximum income for the GIS in 2026?

The income threshold depends on your marital status, and so does the maximum amount paid. Here are the amounts for the quarter published as of March 31, 2026 — these figures are indexed each quarter (January, April, July, October):

• Single, divorced or widowed — annual income below $22,512; maximum GIS up to $1,109.85 per month.
• Spouse receives the full OAS — combined couple income below $29,760; maximum GIS up to $668.08 per month.
• Spouse receives the Allowance — combined income below $41,664; maximum GIS up to $668.08 per month.
• Spouse receives neither OAS nor the Allowance — combined income below $53,952; maximum GIS up to $1,109.85 per month.

The GIS is recalculated every year from your previous year’s tax return — which is why you must file by April 30, even though the GIS itself isn’t taxable.

What counts as income for the GIS?

This is where planning becomes possible. The income used to calculate the GIS is your net income (before adjustments), excluding the OAS and the GIS themselves. What counts, and what doesn’t, changes the effect of your withdrawals dramatically:

• Counts as income: the RRQ (the Quebec Pension Plan, QPP), employer pensions, interest and dividends, and above all withdrawals from an RRSP or RRIF (FERR) — every dollar withdrawn adds to net income.
• Doesn’t count: TFSA withdrawals (never included in net income), the OAS, and the GIS.
• Partly exempt: employment or self-employment income. The first $5,000 is fully exempt, and 50% of the next $10,000 is exempt too — an exemption designed for seniors who work a little.

The consequence is direct: at the same retirement income, a dollar taken from a RRIF reduces your GIS, while a dollar taken from a TFSA does not.

The GIS as a lever: the roughly 50% reduction rate

The GIS drops as income rises, at a rate of about 50 cents per dollar of counted income (the rate can be higher in some bands, where other benefits combine). This implicit reduction rate is steep: it’s the equivalent of a 50% marginal tax stacked on top of ordinary tax, on the slice of income that eats into the GIS.

That opens a planning window between stopping work and 65, or in the early GIS years: if your income is naturally low, withdrawing from a RRIF at that point can be costly in lost GIS, whereas the same cash need met from the TFSA leaves the supplement untouched. Conversely, drawing down the RRSP before claiming the OAS and GIS — during years when no GIS is at stake — can lighten the RRIF balance that would later inflate income and reduce the supplement.

The drawdown order of the RRSP, TFSA and RRIF decides which account feeds your income each year

GIS and the OAS clawback: two opposite mechanisms

Watch out for a common confusion. The GIS and the OAS clawback act at the two opposite ends of the income scale:

• The GIS targets low incomes: it drops by about 50% per dollar and disappears once income exceeds the thresholds above (about $22,512 for a single person).
• The OAS clawback targets high incomes: it only begins above $95,323 of net income (2026 income year), at a 15% rate, and fully recovers the OAS at about $154,753 (for those aged 65 to 74).

These are two distinct rules that almost never touch the same person in the same year. But they share a logic: in both cases, a TFSA withdrawal doesn’t count as income, while an RRSP or RRIF withdrawal does. Managing your net income means managing both.

At the other end of the scale, the OAS clawback follows the same net-income logic

The Allowance for a spouse aged 60 to 64

If you receive the GIS and your spouse is between 60 and 64, they may qualify for the Allowance — a separate benefit meant to bridge the period before they become eligible for the OAS themselves. It has its own conditions (residence, citizenship or legal status, and a combined income threshold). It’s a piece to fold into the plan of a couple with an age gap, because it changes the income and the thresholds that apply.

Frequently asked questions

Before you claim the GIS

• Check your marital status and the matching income threshold — they differ sharply between a single person and a couple.
• Look at where your cash will come from: a TFSA withdrawal doesn’t touch the GIS, an RRSP or RRIF withdrawal reduces it by about 50%.
• Consider drawing down the RRSP before 65, during years with no GIS at stake, to lighten future income.
• Coordinate it all with your drawdown order and the OAS clawback: all three decisions turn on the same net income.
