A genuine supplier invoice is missing from GSTR-2B for the month, and the finance executive wants to know whether the ITC can still be claimed.
Section 16(2)(aa) ties ITC to invoices reported by the supplier. Credit is claimed in the month the invoice appears in GSTR-2B, within the Section 16(4) deadline; self-assessed reverse-charge credit is the main exception.
A missing-invoice tracker with supplier, invoice value, GST, reason missing, follow-up date and the GSTR-2B month in which it finally appears.
No ITC claimed ahead of GSTR-2B, every missing invoice followed up, and each credit claimed in the correct month before 30 November.
In general, no. Input tax credit (ITC) on a supplier’s invoice can be claimed only when that invoice appears in your GSTR-2B. If it is missing this month, you wait, follow up with the supplier, and claim it in the month it shows up, as long as that is within the Section 16(4) time limit.
What changed from 1 January 2022 when the provisional credit allowance ended?
Before 2022, Rule 36(4) of the CGST Rules let you claim a little more than what suppliers had uploaded. That extra margin started at 20 percent in 2019, came down to 10 percent and then 5 percent, and became nil from 1 January 2022. At the same time, Section 16(2)(aa) of the CGST Act, 2017, made it a condition that the supplier must have reported the invoice and it must have been communicated to you.
Since October 2024, the Invoice Management System (IMS) sits in front of GSTR-2B. You accept, reject or keep pending each invoice there. Invoices with no action are deemed accepted when GSTR-2B is generated on the 14th. An invoice you keep pending will not be in this month’s GSTR-2B either.
Why is the invoice missing, and what should I do?
| Why it is missing | What to do |
|---|---|
| Supplier has not filed GSTR-1 or IFF | Remind the supplier; claim when it appears |
| Supplier filed after the GSTR-1 due date (11th) | It will appear in next month’s GSTR-2B; claim then |
| You kept it pending in IMS | Take action in IMS; it moves to a later GSTR-2B |
| Supplier used a wrong GSTIN | Ask them to amend GSTR-1 to your GSTIN |
| Import of goods | Check the import section of GSTR-2B against the bill of entry |
| Reverse-charge purchase | Not supplier-driven; claim on the tax you paid yourself |
What risk do I run if I claim it anyway?
The department compares GSTR-3B Table 4 with GSTR-2B every month. Excess claims are flagged. If the credit is found ineligible, you repay it with interest. Where wrongly availed credit has been used, interest under Section 50(3) is 18 percent a year. Penalties can follow. A one-month wait is far cheaper.
Worked example
A ₹23,600 invoice dated 25 September (₹20,000 plus GST at 18 percent of ₹3,600) is missing from September’s GSTR-2B. The supplier filed late, and the invoice appears in October’s GSTR-2B, generated on 14 November.
- September GSTR-3B (due 20 October): do not claim the ₹3,600.
- Add the invoice to your missing-invoice tracker.
- October GSTR-3B (due 20 November): claim the ₹3,600.
The cost of waiting is only one month of the ₹3,600 sitting in the tracker. If the supplier never files, the credit is lost after 30 November 2027 for an invoice of FY 2026-27, so start supplier follow-ups early.
