What a CGEB underpayment means
A CGEB underpayment is a Canada Groceries and Essentials Benefit deposit that lands lower than you expected, or lower than the previous quarter. CGEB replaced the GST/HST credit in July 2026 — Finance Canada announced it in January 2026 and Parliament passed it in February 2026. So underpayment questions apply from the first quarterly deposit onward.
CGEB is income-tested. The amount is not fixed: it depends on your adjusted family net income (AFNI) and your household size, and it can be recalculated during the year. A lower-than-expected deposit is usually the system working as designed rather than an error — the trick is knowing which cause is in play.
TL;DR: a CGEB underpayment is almost always one of four things — your AFNI rose and the 5% phase-out ate more of the benefit, a spouse has not filed, the CRA recalculated mid-year, or your marital status or custody changed. Check the AFNI in CRA My Account; the CRA issues a retroactive adjustment once the underlying cause is fixed.
Why a CGEB deposit can be lower than expected
CGEB uses the same AFNI engine and the same recalculation rules as the Canada Child Benefit and the old GST/HST credit, so a low deposit comes down to the same handful of causes:
- Your AFNI rose. CGEB phases out at 5% of every dollar of AFNI above approximately $46,500. A raise, a bonus, investment income, or a smaller RRSP contribution lifts AFNI and shrinks the benefit. A $10,000 higher AFNI above the threshold reduces CGEB by $500 a year.
- A return was filed late or not at all. CGEB is calculated from filed returns. If one spouse has not filed, the CRA cannot determine the couple amount and the benefit is reduced or paused until the return is in.
- The CRA recalculated. A reassessment, corrected income slip, or updated information can change the AFNI mid-year, which adjusts the remaining quarterly deposits.
- Marital status or custody changed. A separation, a new common-law relationship, or a change in who the child primarily lives with all change the entitlement, and the CRA recalculates from the date of the change.
- Transition timing. When CGEB replaced the GST/HST credit in July 2026, the first deposit looked different because the structure and amounts changed. That is a structural difference, not an underpayment.
How to check your CGEB amount
The single source of truth is CRA My Account. The steps mirror what you would do for a CCB amount you wanted to verify:
- Open Benefits and Credits. Sign in at canada.ca and find the CGEB entry. It shows the benefit-year amount, the quarterly schedule, and the AFNI used.
- Read the AFNI. Compare it against your filed return. For a couple, AFNI is both spouses' net income (line 23600 each) added together — walk it through in adjusted family net income explained.
- Compare to the expected amount. Run your numbers in the calculator on this site. If the calculator and the CRA agree, the lower deposit is the phase-out, not a mistake. If they disagree, the AFNI the CRA used is probably different from what you filed.
If the income on the notice is higher than your return, look for an unfiled spouse return, a reassessment, or income the CRA picked up from a slip you did not include.
How a CGEB underpayment gets corrected
CGEB corrections follow the CCB and GST/HST credit pattern exactly. When the cause is fixed — the missing return is filed, the marital status is updated, or a reassessment is processed — the CRA recalculates the benefit and issues a retroactive adjustment for the quarters you were underpaid.
You do not have to claim each quarter individually. The recalculation sweeps the whole period back to the relevant date and the catch-up amount is deposited to the same account. Under the CCB, the CRA can adjust retroactively for up to several years when a late return finally lands, and CGEB uses the same machinery.
The action on your side is almost always the same: file any outstanding return. A family with low or zero income still has to file, because the benefit is calculated from the return and an unfiled return is the most common reason a CGEB deposit comes in low. Once both spouses file, the CRA recalculates and the underpayment resolves itself.
Common questions
What does CGEB underpayment mean?
A CGEB underpayment is a Canada Groceries and Essentials Benefit deposit that is lower than you expected, or lower than a previous quarter. The most common causes are a higher adjusted family net income (AFNI), a tax return that was filed late or not at all, or a mid-year recalculation after a change in marital status or custody. CGEB replaced the GST/HST credit in July 2026, so underpayment questions apply from the first benefit year onward.
Why is my CGEB payment lower than expected?
The usual reasons, drawn from how the CCB and GST/HST credit behave, are: your AFNI rose, which increased the 5% phase-out above ~$46,500; one spouse has not filed, so the CRA cannot calculate the couple amount; the CRA recalculated after new information; or your marital status or the number of children under 19 changed mid-year. The switch from the GST/HST credit in July 2026 can also make a deposit look different from the old credit.
How do I check my CGEB payment?
Sign in to CRA My Account, open Benefits and Credits, and review the CGEB amount, the benefit year, and the AFNI used to calculate it. Compare that AFNI against your filed return. If the income is higher than you expected, the phase-out explains the lower deposit. If a spouse has not filed, the amount stays reduced until they do.
How does the CRA correct a CGEB underpayment?
The same way it corrects the CCB and the GST/HST credit. When the missing return is filed or the corrected information is processed, the CRA recalculates your CGEB and issues a retroactive adjustment for the quarters you were underpaid. You do not need to request each quarter separately — filing the return is what triggers the recalculation and the catch-up payment.
