GST Credit Income Limit 2026: Maximum AFNI by Family Size + Phase-Out Math

The 2026 GST Credit Income Limits by Family Size

The GST/HST credit is a quarterly tax-free benefit paid to Canadians with low and modest incomes. For the benefit year running July 2025 to June 2026 — calculated from your 2024 tax return — the credit phases out completely at a different income for each family structure. Here are the income cutoffs at which the annual GST credit reaches zero, derived from the CRA's published calculation parameters:

A few things to read from this table carefully. First, the cutoffs are the zero point, not the start-of-reduction point. The credit starts to fall at $45,521 of AFNI — well below the cutoffs above. If your income is anywhere between $45,521 and the cutoff for your family size, you receive a partial credit. Second, children must be under 19 and registered for the Canada Child Benefit or the GST/HST credit to count here. Third, the credit amounts include a single-parent supplement: the first child in a single-parent household gets a $349 credit (same as the adult credit), not the $184 child credit. Fourth, AFNI for couples is the combined total of both partners' line 23600 amounts — this catches couples where one earner is near or above the threshold individually but both incomes together cross it.

How the Reduction Actually Works: the 5% Math

The CRA formula for the credit reduction is simple in structure and easy to model: for every dollar of AFNI above $45,521, your annual credit falls by 5 cents. That 5% reduction rate applies uniformly — no faster phase-out for higher incomes, no sharp cliff.

Here is a worked example for a couple in Burlington with combined AFNI of $52,000:

• Maximum annual credit for a couple: $698
• AFNI above the reduction threshold: $52,000 − $45,521 = $6,479
• Reduction at 5%: $6,479 × 5% = $324
• Remaining annual credit: $698 − $324 = $374 (~$93.50 per quarterly payment)

At $59,481, their reduction would hit $698 exactly ($59,481 − $45,521 = $13,960; $13,960 × 5% = $698), and the credit reaches zero. Above that income, no credit, no notice from CRA. The quarterly payments they were receiving simply stop.

What Counts as Income for the GST Credit Test

AFNI is your net income from line 23600 of your T1, not your gross pay. That distinction matters. RRSP contributions, employment expenses, and childcare deductions have already reduced net income before the GST credit income test applies. Here is what does and does not flow into AFNI:

The dividend gross-up is the most common surprise here. An investor holding Canadian dividend-paying stocks or REITs near the $45,521 threshold can push over the reduction threshold simply because eligible dividends are reported at 138% of the cash received. A retiree who received $10,000 in eligible dividends has $13,800 of AFNI from those dividends — $3,800 more than the cash that landed in their account. The CRA dividend tax credit partially offsets the income tax owed on the gross-up, but it does not reduce AFNI for benefit calculation purposes.

The July 2026 Transition: GST/HST Credit Becomes the CGEB

Starting July 3, 2026, the GST/HST credit is replaced by the Canada Groceries and Essentials Benefit (CGEB). The income eligibility rules and the family-size structure are unchanged. What does change is the amount: the federal government has legislated a 25% increase to the base credit amounts, locked in for five years (2026–2031).

Based on the current 2024-base-year maximums and applying a 25% increase (before any 2025-base-year indexation that CRA has not yet announced), the estimated CGEB maximums starting July 2026 are:

These are estimates pending the official CRA announcement of indexed parameters for the July 2026–June 2027 benefit year. The 25% increase applies to the federal credit only — provincial and territorial top-ups (such as Ontario's Ontario Trillium Benefit) are not included in the 25% increase. No application is required if you already receive the GST/HST credit. You will automatically transition to the CGEB. Your bank statement may still label the deposit under the old GST/HST credit name for the first few months as CRA updates its systems.

The income thresholds — the $45,521 reduction start and the family-size zero-cutoffs above — are not changed by the CGEB legislation. Higher amounts but the same income limits means the phase-out happens at a slightly higher dollar amount, but the AFNI numbers where the credit hits zero will move only with regular annual indexation, not by the 25% factor.

The One-Time June 2026 Top-Up: What You Actually Get

As a bridge payment ahead of the CGEB launch, the federal government issued a one-time GST/HST credit top-up starting June 5, 2026. The top-up equals 50% of your total annual entitlement for the July 2025 to June 2026 benefit year. If you received the full $533 annual credit as a single person (paid in four quarterly installments of $133.25), your top-up is $267 (50% × $533). Here are the maximum top-up amounts for each family structure:

The top-up was automatically issued without application if you were entitled to the January 2026 quarterly payment. If your income crossed the zero-cutoff for your family size and your credit was eliminated, you received nothing from the top-up — the gate is active entitlement to the January 2026 payment, not simply having received the credit at some earlier date. In shared custody situations, each parent receives 50% of the top-up they would otherwise be entitled to.

Three Moves to Stay Below the Income Cutoff

1. Contribute to your RRSP before the filing deadline

RRSP contributions deducted in the filing year reduce your net income on line 20800, which directly lowers AFNI. A person earning $50,000 of employment income who makes a $5,000 RRSP contribution brings AFNI to $45,000 — below the $45,521 reduction threshold entirely, keeping the full $533 single credit intact. The math: $5,000 RRSP contribution saves $250 in credit reduction (5% × $5,000) plus the federal and provincial income tax deduction. You need 2026 RRSP contribution room from your 2025 earned income; the 2026 RRSP limit is $33,810 or 18% of your 2025 earned income, whichever is less.

2. Fund discretionary spending from TFSA, not RRIF

If you are a retiree with savings split across a RRIF and a TFSA, the order of withdrawals matters enormously for AFNI. Every dollar pulled from the RRIF is taxable income counted toward your GST credit income test. Every dollar pulled from the TFSA is invisible to AFNI. For a couple sitting at $55,000 of AFNI — already in the reduction zone — replacing a planned $5,000 RRIF withdrawal with a $5,000 TFSA withdrawal saves $250 of GST credit (5% × $5,000) plus reduces their federal and provincial income tax. That is a real-dollar benefit from a bookkeeping choice about which account to tap first. See the 2026 RRIF minimum withdrawal table to understand which RRIF draws are mandatory versus optional.

3. Time capital gains events across tax years

A capital gain on selling a non-registered investment (50% of the gain is included in 2026 income) can push AFNI above the reduction threshold or all the way to zero entitlement in the year of the sale. If you have flexibility in when you trigger a gain — realizing it in January versus December, for example — you can sometimes distribute the gain impact across two benefit years rather than one, reducing the total credit lost. A gain of $20,000 above the $45,521 threshold costs you $1,000 of annual credit (5% × $20,000). That is the only year affected; in the following July, CRA recalculates from the new year's return, and a normal income year restores your credit. The planning point: do not let a manageable capital gain permanently eliminate your credit if deferring the timing is possible.

Payment Dates and the July Reset

The GST/HST credit is paid quarterly on January 5, April 2 (already paid for the 2024 base year), July 3, and October 5 (under the CGEB name starting July 2026), with the standard CRA footnote that you should wait 10 business days before contacting CRA if a payment is missing. Your entitlement resets each July based on your previous year's return. If your 2024 return resulted in a partial or zero credit but your 2025 income is lower, the July 2026 recalculation — now as the CGEB — will restore your entitlement automatically once CRA assesses your 2025 return. For detailed payment dates covering every benefit including OAS and CPP, see the GST/HST credit payment dates 2026.

How the GST Credit Stacks with Other Benefits

The GST credit is one of several federal benefits that use AFNI-based income tests, and they do not all use the same thresholds. Understanding the full picture matters because optimizing for one benefit can affect another:

• Canada Child Benefit (CCB): The 2026 CCB maximum is $7,997 per year for children under 6 and $6,748 for children 6–17. The CCB begins to reduce at AFNI above $37,487 (for 2026–27, announced at $38,237) — well below the GST credit's $45,521 threshold. Families with children are often dealing with CCB reduction and GST credit reduction simultaneously on the same income base. See the 2026 Canada Child Benefit amounts and thresholds for the full phase-out math.
• GIS (Guaranteed Income Supplement for seniors): The GIS income test is far tighter — a single senior loses all GIS at roughly $22,512 of income (excluding OAS). But seniors receiving GIS who also qualify for the GST credit receive both, stacked, because GIS payments are non-taxable and excluded from AFNI. See the 2026 GIS payment amounts for how they interact.
• OAS clawback: The OAS recovery tax threshold is $95,323 for 2026 — far above the GST credit zero-cutoff. If you are earning enough for OAS clawback to apply, you lost GST credit eligibility well below that level.
• Ontario Trillium Benefit: Ontario's combined energy, property, and sales tax credit has its own income test administered jointly with the GST credit through the T1 return. The OTB does not receive the 25% CGEB increase; that increase is federal-only.

The GST credit is not means-tested in the same way as GIS — there is no household assets test, no interview, no application for existing tax filers. If you file your return, CRA automatically calculates your entitlement. The practical upshot: filing your return promptly every year is the only required action. For new residents, Form RC151 replaces the tax return requirement in the first year.
