Every accountant knows the slogan “no 2B, no ITC”. The half that produces notices is the second one: an invoice can sit in your GSTR-2B and still be credit you should not take this month. This post follows one credit from the supplier's return to your GSTR-3B and marks where each check belongs, so that the figure you file is one you can defend.
New to the return? Our guide on what is GSTR-2B explains the basics first.
The path from the supplier's return to your GSTR-3B
Two provisions create this path. Under Section 16(2)(aa) of the CGST Act, effective 1 January 2022, credit is available only when the supplier has furnished the invoice details in the statement of outward supplies and those details have been communicated to you. Rule 36(4) of the CGST Rules says the same thing from the claim side:
“(b) the details of such invoices or debit notes have been communicated to the registered person in FORM GSTR-2B” Source: Rule 36(4), CGST Rules, as amended by notification 40/2021-CT
Before 1 January 2022 the rule allowed provisional credit on invoices the supplier had not yet reported, capped at 5% of the eligible credit. Rule 36(4) as it stands today allows nothing beyond what 2B shows. If a client still “takes 5% extra to be safe”, that habit comes from a rule that no longer exists.
What lands in GSTR-3B
The portal auto-drafts GSTR-3B Table 4 from your 2B (GSTR-3B user guide). The line that carries eligible invoice credit is Table 4(A)(5), “All other ITC” (GSTR-3B help, Table 4). Two things follow for anyone reconciling.
- You reconcile against 2B, not against last month's 3B. The 2B for the month is the reference figure; your books either agree with it, or the difference has a reason you can name.
- What you do in IMS changes the 2B. Records kept Pending are not part of GSTR-2B or GSTR-3B. If you change an action, you can recompute GSTR-2B when you file GSTR-3B and take the corresponding credit (GSTN IMS FAQ). The steps are in how to recompute GSTR-2B, and the accept, reject or pending decision is in the IMS decision tree.
The 2B Excel you download carries the B2B, B2BA, CDNR and CDNRA tables, so amendments and credit or debit notes are part of the same statement. See what GSTR-2B contains if you need the table-by-table view.
Which invoices count towards this month's claim
| Situation | Effect on the 2B | Claim in 3B this month? |
|---|---|---|
| Supplier reported the invoice; it is in your 2B | Included | Yes, if the checks in the next section also pass |
| Supplier has not filed GSTR-1 or IFF | Not shown | No. Section 16(2)(aa) and Rule 36(4) block it |
| You kept the invoice Pending in IMS | Not part of 2B or 3B | No, until you accept it and recompute 2B before filing |
| You rejected the invoice in IMS | Can be changed back to accepted before filing 3B | Only after you change the action and recompute |
| In 2B, but the goods or services have not arrived | Included | No. Section 16(2)(b) requires actual receipt |
| In 2B, but the supplier has been unpaid beyond 180 days | Included | Reverse it under Rule 37; re-claim on payment |
| Invoice of an earlier financial year, after the Section 16(4) date | May still be shown | No. The time limit has passed |
What GSTR-2B does not check
The 2B is built from what suppliers report. It knows nothing about your godown, your bank statement or your calendar. Three conditions therefore stay with you.
- Receipt. Section 16(2)(b) requires that “he has received the goods or services or both”. An invoice for a consignment stuck at the transporter is in your 2B and still not claimable.
- Payment. Under Rule 37 credit must be reversed, with interest, if the supplier is not paid within 180 days from the invoice date, and can be re-availed once payment is made. Reverse-charge supplies are outside this rule. The 2B will never prompt you.
- Time. The Section 16(4) limit is 30 November following the end of the financial year, or the date of the annual return, whichever is earlier. For invoices of FY 2025-26 that means 30 November 2026 at the latest. The full treatment is in the Section 16(4) guide.
Common mistake: treating the 2B total as the number to claim. Take the 2B total, then deduct what fails receipt, and flag what is close to 180 days or to the 30 November date.
Why claiming beyond 2B ends in a notice
GSTN compares the ITC available in your GSTR-2B with the ITC you claim in GSTR-3B. When the claim exceeds 2B by more than a pre-defined limit, the system generates an intimation in Form DRC-01C. The official wording:
“If there is a difference between the ITC available as per GSTR-2B and ITC claimed in GSTR-3B/3BQ that exceeds a pre-defined limit, you will receive an intimation in Form DRC-01C. In such cases, it is mandatory to file Form DRC-01C Part B to provide the necessary details and reconcile the difference.” Source: GSTN advisory on ITC mismatch intimation in Form GST DRC-01C
We do not quote the limit because the advisory calls it “pre-defined” without a number in the text we checked; look at the current advisory for it. What matters for your process is that the trigger is arithmetic. If credit was wrongly availed and also utilised, interest under Section 50(3) runs at 18% a year (notification 13/2017-CT as amended). The reply process is in the DRC-01C guide, and the 2B versus 3B distinction is in GSTR-2B vs GSTR-3B.
Worked example: from books to the figure you file
A distributor in Indore closes the September 2026 tax period. Its purchase register carries ITC of ₹3,86,500. GSTR-2B is generated on 14 October 2026 and GSTR-3B is due on 20 October 2026 for a monthly filer.
| Line | Amount | Note |
|---|---|---|
| ITC in the purchase register | ₹3,86,500 | All invoices booked for September |
| Less: supplier has not filed GSTR-1 | ₹45,000 | One invoice, not in 2B |
| Less: kept Pending in IMS | ₹18,000 | Not in 2B until accepted |
| Add: in 2B, not yet booked | ₹6,000 | Book it, then it counts |
| ITC shown in GSTR-2B | ₹3,29,500 | 3,86,500 − 45,000 − 18,000 + 6,000 |
| Less: goods not yet received | ₹12,500 | In 2B, but Section 16(2)(b) fails |
| Claimable on 20 October | ₹3,17,000 | 3,29,500 − 12,500 |
The accountant then verifies the ₹18,000 invoice, finds the goods received and the bill correct, accepts it in IMS and recomputes GSTR-2B before filing. The 2B becomes ₹3,47,500, and the claim becomes ₹3,35,000 after the same ₹12,500 hold. The ₹45,000 waits for the supplier to report the invoice.
Now the wrong way. If the firm had claimed the register figure of ₹3,86,500 against a 2B of ₹3,29,500, the claim would exceed 2B by ₹57,000 (45,000 + 18,000 − 6,000). That gap is what the system compares. If the excess were utilised for 30 days, interest at 18% a year comes to about ₹843 (57,000 × 18% × 30 ÷ 365, rounded to the nearest rupee as Section 170 requires). The interest is small. The DRC-01C, the Part B reply and the supplier-chasing done under notice are the real cost.
The same figures feed the annual return
The 2B does not stop mattering after the 20th. In the GSTR-9 manual, Table 8A is auto-filled from GSTR-2A until FY 2022-23, and from FY 2023-24 it is auto-filled from GSTR-2B and cannot be edited (GSTR-9 manual). A monthly habit of matching your claim to 2B is therefore also what makes your annual reconciliation short.
Three habits that keep the claim clean
- File from the recomputed 2B, not from the first download. If you acted on IMS after the 14th, download again. The 14th-to-20th plan lays out the sequence.
- Keep a hold list next to the reconciliation. Every invoice in 2B that you decline to claim (receipt pending, disputed, near 180 days) goes on it with a date and a reason.
- Chase the supplier before the 14th, not after. The 14th is the day 2B is generated, so that is your reference date; what a later filing does is explained in the freeze-date guide. Supplier not filing GSTR-1 has the follow-up steps.
Frequently asked questions
Can I claim ITC in GSTR-3B on an invoice that is not in GSTR-2B?
No. Since 1 January 2022, Section 16(2)(aa) and Rule 36(4) allow ITC only on invoices that the supplier has reported and that the portal has communicated to you in GSTR-2B. The old provisional buffer was removed.
Is everything shown in GSTR-2B safe to claim?
No. GSTR-2B does not test whether you received the goods or services, whether you paid the supplier within 180 days, or whether you are inside the Section 16(4) time limit. Those checks remain yours.
Which GSTR-3B table takes the ITC from GSTR-2B?
Eligible ITC from GSTR-2B is auto-populated in Table 4(A)(5), All other ITC. Credit that does not come from supplier invoices, such as tax you pay under reverse charge, is not part of this line, so check the GSTR-3B help text for those.
See your own gap before you file
Drop the month's GSTR-2B (Excel or JSON) and your purchase register into gstr2bmatch.in. The report shows matched invoices, value mismatches, invoices missing from 2B and the rupee ITC at risk. It cannot read your live IMS dashboard, so confirm Pending items on the portal. Your GSTR-2B and purchase register files are read in your browser and never uploaded to any server.
