GSTR-2B in 2026: How the Auto-Drafted ITC Statement Works with IMS, and How to Reconcile It

GSTR-2B decides how much input tax credit you can claim each month, so it's worth understanding properly. You never file it — the GST portal builds it from what your suppliers upload — but since October 2024 the Invoice Management System (IMS) lets you accept, reject or hold those documents before the statement is finalised. This guide is for business owners and accountants who claim ITC. It covers when GSTR-2B is generated, the cut-off dates, how IMS actions change it, the 2025 updates and the changes now proposed, Rule 36(4), and a worked ₹ reconciliation of a trader's books. Checked against the GST portal, CGST Rules and GSTN advisories in October 2026.

Quick answer

GSTR-2B is a read-only, auto-drafted statement of the input tax credit available to you for a month (or a quarter if you're in QRMP). It's built from your suppliers' GSTR-1, GSTR-1A and IFF, ISD and non-resident returns, and import data from customs, and it's generated on the 14th of the following month. Its ITC figures auto-fill Table 4 of your GSTR-3B.

• Rule 36(4): you can claim ITC on supplier invoices only if they appear in your GSTR-2B

• On IMS you accept, reject or keep invoices pending; anything left untouched is deemed accepted on the 14th

• Act on IMS after the 14th? Recompute GSTR-2B before filing GSTR-3B

• From October 2025, credit notes can be kept pending for one tax period (a month, or a quarter for QRMP filers) only

What is GSTR-2B and why does it matter?

GSTR-2B is the statement of input tax credit referred to in section 38 of the CGST Act and Rule 60(7). For each tax period it lists, document by document, the credit your suppliers have made available to you, the credit you must reverse because of credit notes, and the credit you can't take at all.

Two legal provisions turn it from an information sheet into a limit. Section 16(2)(aa) says you can take credit only if the supplier has furnished the invoice details and they have been communicated to you. Rule 36(4), in force since 1 January 2022 (Notification 40/2021-CT), says those details must appear in GSTR-2B. The old tolerance that allowed a small percentage of credit on invoices missing from the statement is gone. If it's not in GSTR-2B, you wait until it is.

GSTR-2B also drives what the portal expects to see in your GSTR-3B. The figures flow automatically into Table 4, and if your claim runs too far ahead of the statement, Rule 88D lets the portal send a DRC-01C intimation asking you to pay the excess with interest or explain it within seven days. Many of the scrutiny notices businesses now receive start with a gap between books, GSTR-2B and GSTR-3B — see our guide to replying to GST notices.

Who gets a GSTR-2B? Normal taxpayers (including SEZ units and developers) and casual taxpayers. Composition dealers don't, because they can't claim ITC; they see GSTR-4A instead. Input Service Distributors, non-resident taxable persons and TDS/TCS registrants don't get one either.

When is GSTR-2B generated, and what are the cut-off dates?

For a monthly filer, GSTR-2B for a month is generated on the 14th of the following month. For a QRMP filer, GSTR-2B isn't generated for the first two months of the quarter; a single quarterly statement (the portal calls it GSTR-2BQ) is generated on the 14th of the month after the quarter.

What goes into it depends on when your supplier filed, not the invoice date. The portal's cut-off windows are:

So an invoice dated 20 May that your supplier only uploads in its September GSTR-1, filed on 11 October, lands in your September GSTR-2B, not May's. If the same supplier files on 12 October, it moves to October's GSTR-2B. This is why a supplier filing one day late can push your credit back a month.

When it isn't generated. If you haven't filed GSTR-3B for the previous period, the portal won't generate the next GSTR-2B on the 14th. Once you file the pending return, you can generate it from the IMS dashboard.

How IMS changed GSTR-2B

The Invoice Management System went live on 1 October 2024, and taxpayers could act on documents from 14 October 2024. Every invoice, debit note and credit note your supplier saves or files in GSTR-1, GSTR-1A or IFF appears on your IMS dashboard (Services → Returns → Invoice Management System). You can then:

• Accept — the record goes into the "ITC available" part of GSTR-2B and its credit auto-fills GSTR-3B.
• Reject — the record goes into an "ITC rejected" section, shown for reference only, and none of its credit flows to GSTR-3B.
• Keep pending — the record stays out of GSTR-2B and GSTR-3B and waits on IMS until you decide, up to the section 16(4) time limit. Pending isn't allowed for every document type.
• No action — the default. Anything still on "No Action" when GSTR-2B is generated is deemed accepted.

You can change your action as many times as you like until you file GSTR-3B for that period; the latest action wins, and it freezes when the return is filed. If you act after the 14th, you must recompute GSTR-2B from the IMS dashboard before filing GSTR-3B, otherwise your return uses the old figures. There is no limit on how often you recompute.

What never appears on IMS but still goes straight into GSTR-2B: reverse-charge invoices, documents from GSTR-5 and GSTR-6, ICEGATE import records, invoices where credit is barred by section 16(4) or the place-of-supply rules, and Rule 37A reversals.

What a supplier sees. Your actions show on the supplier's outward-supplies view in IMS. If you reject an invoice after they've filed GSTR-1, they correct it through GSTR-1A or a later GSTR-1, and the corrected record comes back to your IMS for fresh action. If you reject a supplier's credit note, the supplier's output tax isn't reduced by it.

The 2025 and 2026 changes to IMS

How IMS and GSTR-2B have evolved

1 Jan 2022

Rule 36(4) limits ITC to invoices shown in GSTR-2B

14 Oct 2024

IMS live: accept, reject or keep pending; no action = deemed accepted

1 Oct 2025

Finance Act 2025 amendments to sections 34(2) and 38 in force — a supplier's credit note cuts its tax only if you reverse the ITC

October 2025 period

Credit notes can be kept pending for one tax period; you declare the ITC actually availed when reversing; remarks on reject/pending

8 Oct 2026

57th GST Council recommends Rule 60(6A) for IMS, an electronic credit reversal and reclaim statement (Rule 86C) and an ITC-correction mechanism (Rule 61(1B))

April 2027 return (proposed)

New mechanism for amending liability and ITC in returns, after public consultation

October 2025 period onwards. GSTN's advisory of 23 September 2025 made three changes. First, specified records — credit notes and their upward amendments, downward amendments of a credit note you rejected, and downward amendments of an invoice or debit note you already accepted and claimed in GSTR-3B — can now be kept pending, but only for one tax period (a month, or a quarter for QRMP filers), counted from the period in which the supplier reported the document. Second, when you accept such a record you can declare how much ITC you actually availed, so if you never took the credit (or took only part of it), you reverse only that amount. Third, you can add remarks when you reject or hold a record; suppliers see them on their dashboard.

On 8 October 2025 GSTN also clarified, against social-media claims, that ITC still auto-populates from GSTR-2B into GSTR-3B and GSTR-2B is still generated automatically on the 14th.

What's coming. The 57th GST Council (8 October 2026) recommended inserting Rule 60(6A) to give IMS a specific footing in the rules, including how long a credit note can stay pending, plus an Electronic Credit Reversal and Reclaim Statement (Rule 86C) and a mechanism under Rule 61(1B) to correct ITC in GSTR-3B so it lines up with GSTR-2B. The Council suggested these take effect from the April 2027 return, after public consultation. None of this is notified yet; until it is, the current portal behaviour described above applies.

What's inside a GSTR-2B: table by table

Download GSTR-2B from Services → Returns → Returns Dashboard → GSTR-2B tile, as a PDF summary or in Excel or JSON. Above 1,000 documents, use the advanced search or download the full file.

A negative figure in a GSTR-2B section (usually from a downward amendment or a large credit note) isn't carried as a negative into some GSTR-3B fields — reverse-charge Table 3.1(d), for example, auto-fills as zero — so check the system-generated GSTR-3B PDF for how the portal has treated it.

Remember that GSTR-2B only flags two kinds of ineligible credit. Blocked credit under section 17(5) — motor vehicles, food and beverages, club memberships, works contracts for immovable property and the like — will show as "available" if the supplier charged GST. You still have to reverse it yourself in Table 4B(1) of GSTR-3B. Our input tax credit guide lists what's blocked.

Worked example: reconciling a trader's books with GSTR-2B

Mehta Traders in Ahmedabad is a monthly filer. Its purchase register for September 2026 shows ITC of ₹3,06,000, after a supplier's credit note of ₹4,000 tax for a volume discount. On 15 October, before filing GSTR-3B, the accountant matches the register against IMS and GSTR-2B.

What IMS shows, and what Mehta does:

1. 38 invoices carrying ₹2,74,500 of tax match the register exactly → accept.
2. An invoice for a car repair, tax ₹2,500, matches the register → accept, but note that credit on motor vehicle repairs is blocked under section 17(5) unless an exception applies.
3. The supplier's credit note for ₹4,000 tax matches → accept, declaring the full ₹4,000 as ITC availed earlier.
4. An invoice for tax of ₹6,000 is on IMS, but the goods are still in transit — section 16(2)(b) needs receipt → keep pending.
5. A supplier has uploaded the same invoice twice; the duplicate carries ₹7,200 tax and isn't in the register → reject, with a remark.

Two items in the register aren't on IMS at all: a bill of entry for imported packing machinery spares with IGST of ₹9,000 (it comes straight into GSTR-2B from ICEGATE), and an invoice for ₹18,000 tax from a supplier who hasn't filed its September GSTR-1 by 11 October.

Because Mehta acted after the 14th, the accountant recomputes GSTR-2B. The recomputed statement shows:

The reconciliation. Books ₹3,06,000 minus GSTR-2B ₹2,82,000 leaves ₹24,000, explained by the ₹18,000 invoice the supplier hasn't uploaded and the ₹6,000 invoice kept pending. Nothing is unexplained, so Mehta can file.

In GSTR-3B for September: Table 4A(1) imports ₹9,000; Table 4A(5) all other ITC ₹2,73,000 (₹2,77,000 less the ₹4,000 credit note). In Table 4B(1) it reverses the blocked ₹2,500. Net ITC claimed: ₹2,79,500. It doesn't add the missing ₹18,000 by hand — that would breach Rule 36(4) and risk a DRC-01C.

In October: once the goods arrive, Mehta accepts the pending ₹6,000 invoice. If the supplier files its GSTR-1 by 11 November, the ₹18,000 invoice appears in October's GSTR-2B and is claimed then. If it still hasn't appeared by the end of the year, Mehta follows up with the supplier — credit for FY 2026-27 must be taken by 30 November 2027 (or the annual return date, if earlier).

How to reconcile GSTR-2B with your books every month

Reconciliation isn't only about matching invoices. Two reversal rules work alongside it, and neither is fully visible from the IMS screen.

Rule 37A (supplier not paying). If your supplier filed GSTR-1 but hasn't filed its GSTR-3B for that period by 30 September after the year, GSTR-2B shows the credit in its "ITC reversed" section and you must reverse it by 30 November after the financial year, or pay it with interest. You can re-claim it once the supplier files.

Rule 37 (you not paying). Separately, if you don't pay a supplier within 180 days of the invoice date, you reverse that credit with interest and re-claim it when you pay. GSTR-2B won't tell you this — your payables ledger will.

A monthly GSTR-2B routine

1. 1

   Download IMS data early

   From about the 12th, download the IMS Excel and your purchase register for the month. Match on supplier GSTIN, invoice number, date, taxable value and tax.

   Tip: Most mismatches are invoice-number formats (INV/001 vs INV-001) — normalise before matching.

2. 2

   Act on every record

   Accept matches, reject duplicates and invoices that aren't yours, and keep pending only what you genuinely can't decide (goods in transit, disputed rates). Don't rely on deemed acceptance.

3. 3

   Chase missing suppliers

   List invoices in your books that aren't on IMS. Ask suppliers to file GSTR-1 or IFF before the cut-off, or GSTR-1A if they already filed.

4. 4

   Recompute GSTR-2B

   If you acted after the 14th, recompute GSTR-2B on the IMS dashboard so GSTR-3B picks up your latest actions.

5. 5

   Adjust GSTR-3B Table 4

   Reverse blocked credit (4B(1)), Rule 42/43 and Rule 37 reversals, and record ineligible ITC in 4D. Keep a working file showing books → GSTR-2B → GSTR-3B.

6. 6

   Track carry-forwards

   Keep a running list of pending, rejected and missing invoices and clear it every month before the section 16(4) deadline.

A few rules make the routine easier. Reconcile before your supplier's cut-off where you can — a call on the 9th gets an invoice into this month's GSTR-2B; a call on the 13th usually doesn't. For QRMP suppliers, ask them to use IFF for B2B invoices in the first two months so you aren't waiting for the quarterly GSTR-1.

Common GSTR-2B problems and how to fix them

Supplier filed, but invoice is missing. Check the filing date. If it fell after the cut-off, it will be in next month's GSTR-2B. Check the GSTIN on the invoice too — a supplier who typed the wrong GSTIN has sent your credit to someone else and must amend the invoice in GSTR-1A or the next GSTR-1.

Invoice in "ITC not available". Either the invoice was uploaded after the section 16(4) deadline for that year, or the supplier charged CGST and SGST of its own state when you are registered in another state (it should have charged IGST). The first can't be fixed. For the second, ask the supplier to amend the place of supply and tax type.

Credit note you don't agree with. Since the October 2025 period you can hold it for one tax period while you check, then accept or reject. If you accept, declare the ITC you actually claimed on the original invoice. If the credit note is legitimate, rejecting it only delays matters — and leaves your supplier's tax unreduced, which usually leads to a dispute.

GSTR-3B ITC higher than GSTR-2B. If you claimed credit outside GSTR-2B — for example by keying in last month's late invoice by hand — expect a DRC-01C. Reply within seven days, either paying the excess through DRC-03 with interest at 18% a year or explaining the difference (for instance, credit taken in an earlier period). Unanswered intimations turn into demand notices.

Accepted something by mistake. Before GSTR-3B is filed, change the action and recompute. After filing, the action is frozen; reverse the excess credit in the next GSTR-3B, with interest if you used it.

What to do next

Set two calendar reminders: the 9th of each month to chase suppliers who haven't uploaded, and the 15th to act on IMS, recompute GSTR-2B and reconcile before your GSTR-3B is due. If you're a supplier, remember the same system works in reverse — your buyers see every GSTR-1 record on their IMS, so issue clean invoices with our free invoice generator and send proper credit notes when prices change.

Frequently asked questions

When is GSTR-2B generated?

GSTR-2B is generated on the 14th of the following month. Monthly filers get one statement for each month; QRMP filers get one statement for the whole quarter on the 14th of the month after the quarter. It is not generated if your previous GSTR-3B is unfiled — file that return and generate it from the IMS dashboard.

What is the difference between GSTR-2A and GSTR-2B?

GSTR-2A is dynamic: it keeps changing whenever a supplier uploads or amends a document, whenever they do it. GSTR-2B is a static statement frozen for a period using fixed cut-off dates, and it reflects your IMS accept/reject actions. ITC in GSTR-3B is auto-filled from GSTR-2B, and Rule 36(4) ties your claim to it, so GSTR-2B is the one to reconcile.

Can I claim ITC that is not in GSTR-2B?

No. Since 1 January 2022, Rule 36(4) and section 16(2)(aa) allow ITC on supplier invoices and debit notes only when they appear in your GSTR-2B. If a supplier uploaded late, the invoice shows in a later month's GSTR-2B and you claim it then, as long as you are within the 30 November time limit under section 16(4).

What happens if I take no action on IMS?

Records left with 'No Action' are treated as accepted when GSTR-2B is generated, so their credit flows into your GSTR-3B. That's convenient but risky: duplicate or wrong invoices will also be deemed accepted. Reject documents you don't recognise and keep pending those you can't yet decide on, where pending is allowed.

How long can I keep a credit note pending on IMS?

From the October 2025 tax period, a credit note (or its upward amendment) can be kept pending for only one tax period (a month, or a quarter for QRMP filers). After that you must accept or reject it. When you accept, you can declare how much ITC you had actually claimed, so you reverse only that amount rather than the full tax on the note.

Can I edit GSTR-2B if a supplier made a mistake?

No. GSTR-2B is read-only. If a supplier's invoice is wrong, reject it on IMS before you file GSTR-3B and ask the supplier to correct it through GSTR-1A or their next GSTR-1. The corrected record lands back on your IMS for fresh action, and the credit flows into a later GSTR-2B.
