- GST Appellate Tribunal (GSTAT)
- Issue
- GSTR-3B vs GSTR-2A ITC mismatch
- Demand
- ~₹6.35 lakh under Section 73
- Result
- Remanded for invoice-wise verification
The short version
- The GST Appellate Tribunal has held that the entire difference between GSTR-3B and GSTR-2A cannot be treated as ineligible ITC without examining the taxpayer's reconciliation and invoices.
- It cuts both ways: the taxpayer can't claim ITC just because an invoice exists or the supplier erred (the burden of proof is on the claimant under Section 155) — but the department can't disallow the whole mismatch without verifying it.
- For FY 2017-18 and 2018-19, CBIC Circular 183/2022 gives a defined mechanism to prove genuine credit through supplier or CA/CMA certificates.
- The officer was directed to do a category-wise and invoice-wise verification — not sustain a demand on the raw numerical gap alone.
If your business ever got a GST notice comparing your GSTR-3B credit with your GSTR-2A and demanding the difference, this ruling matters to you. Now that the GST Appellate Tribunal is up and running, one of the first questions it has tackled is the most common demand in the system — and the answer is refreshingly sensible.
What the dispute was about
A taxpayer received a demand under Section 73 of roughly ₹6.35 lakh (CGST and SGST) on the ground that the ITC claimed in GSTR-3B exceeded what was reflected in GSTR-2A. The department treated the gap, by itself, as excess or ineligible credit. The taxpayer's case was that the difference wasn't wrongful ITC at all — it was made up of several ordinary, explainable components — and that the demand had been confirmed without a real opportunity to present the reconciliation.
The principle: it cuts both ways
The Tribunal's core holding is balanced, and that balance is the takeaway. A mismatch is neither an automatic loss for the taxpayer nor an automatic win.
What the taxpayer can't do
Claim ITC merely because an invoice exists, or merely because the mismatch is the supplier's fault. Section 155 puts the burden of proving entitlement squarely on the person claiming the credit.
What the department can't do
Treat the entire GSTR-3B vs GSTR-2A difference as ineligible without examining the reconciliation and supporting evidence. The number alone doesn't prove the credit is wrong.
So the officer was directed to verify eligibility category-wise and invoice-wise under Sections 16 and 155 — a real examination, not a spreadsheet subtraction.
A mismatch usually isn't "fake" ITC
The reason this matters is that a GSTR-3B vs GSTR-2A gap has many innocent causes — especially in the early GST years. In this case the taxpayer broke the difference down into exactly these buckets:
| Component of the gap | Why it isn't wrongful ITC |
|---|---|
| Reverse charge (RCM) | Tax is paid by the recipient directly — it doesn't flow through a supplier's B2B return, so it won't sit in GSTR-2A. |
| Supplier reporting errors | The supplier filed GSTR-1 wrongly or late; the recipient's credit is still genuine. |
| B2C instead of B2B | Supplier tagged a B2B sale as B2C, so it never mapped to the buyer's GSTIN in 2A. |
| IGST instead of CGST/SGST | Supplier reported under the wrong tax head — the tax still reached the government. |
| Available in 2A, not claimed in 3B | The taxpayer under-claimed — the opposite of excess ITC. |
| Reversed in a later year | Credit already given back, so it can't be demanded again. |
Circular 183/2022: the proof mechanism
For FY 2017-18 and FY 2018-19 — when supplier-side GSTR-1 errors were rampant — CBIC Circular No. 183/15/2022-GST (27 December 2022) tells officers to verify such differences rather than summarily disallow them, using certificates scaled to the amount:
| Difference per supplier (in a FY) | What proves the credit |
|---|---|
| Up to ₹5 lakh | Certificate from the supplier confirming the supply was made and tax was paid. |
| More than ₹5 lakh | Certificate from a Chartered Accountant or Cost Accountant (with UDIN) confirming the same. |
The Tribunal added a useful point: certificates the taxpayer obtained after the appellate order weren't "new grounds of appeal" — they were simply documents to be considered within the Circular 183 framework, because the underlying invoices belonged to the disputed year.
The tax-head example worth knowing
One supplier (renting immovable property) had wrongly reported the tax as IGST, while the taxpayer correctly claimed CGST + SGST. Since the property and supplier were in the same state, the supply was intra-state (Section 8(2) IGST) with the place of supply being the property's location (Section 12(3)). The tax had reached the government; only the head was wrong. The Tribunal treated the taxpayer's CGST/SGST credit as lawful — the error was the supplier's reporting, not the recipient's claim.
RCM stands apart — don't judge it by GSTR-2A at all
Reverse-charge credit runs on a different track: you pay the tax yourself and claim it, so it never depends on a supplier's B2B reporting. It cannot be examined by a GSTR-2A comparison. RCM liability, tax paid and the matching credit have to be verified independently on their own documents.
What taxpayers should take from this
- Reconcile category-wise, not just totals. Break your 3B–2A gap into RCM, supplier errors, B2C/B2B, tax-head errors, unclaimed credit and reversals — the way this taxpayer did.
- Build the Circular 183 file. For FY 2017-18/18-19 gaps, gather supplier certificates (≤ ₹5 lakh) or CA/CMA certificates (> ₹5 lakh) per supplier.
- Keep the burden in mind. Section 155 means you must prove entitlement — an invoice alone isn't enough; tie each credit to real inward supply and tax paid.
- Show up and respond. Missed hearings sink good cases. Reply to notices and attend — natural-justice relief exists, but you can't rely on it.
