GSTR-2A vs GSTR-2B: Which One Decides Your Credit
GSTR-2B decides your input tax credit. Since 1 January 2022 you can claim credit on a supplier's invoice only if it appears in your GSTR-2B. GSTR-2A is a running view of what suppliers have filed, and it keeps changing. Use 2A to track suppliers and old years, and use 2B to fill GSTR-3B.
- GSTR-2B is a fixed monthly statement, generated on the 14th of the next month. Quarterly filers get one for the quarter on the 14th after the quarter ends.
- GSTR-2A updates every time a supplier files or amends, even after your month is closed.
- Section 16(2)(aa) of the CGST Act and rule 36(4) tie your credit to GSTR-2B from 1 January 2022.
- With the Invoice Management System, the 2B of the 14th is a draft. Your accept, reject and pending actions change it, and you recompute it before filing GSTR-3B.

Why are there two statements?
Both show the purchases your suppliers have reported against your GSTIN. The difference is time.
GSTR-2A is live. If a supplier files a July invoice in October, it appears in your July GSTR-2A in October. That is good for seeing everything, but bad for filing, because the number you claimed in July no longer matches what 2A shows later.
GSTR-2B is a snapshot. For a monthly filer it takes documents filed from the 12th of one month to the 11th of the next, by filing date, and freezes them. A late invoice simply lands in the next open 2B. So the credit figure you file against does not move under you. That is why the law chose 2B.
GSTR-2A and GSTR-2B side by side
| Point | GSTR-2A | GSTR-2B |
|---|---|---|
| Nature | Dynamic, changes as suppliers file | Static for the period once generated |
| When | Updates continuously | 14th of the next month, or 14th after the quarter for quarterly filers |
| Basis of a document | The invoice's own period | The date the supplier filed it, within the cut-off |
| Decides your credit | No, from 1 January 2022 | Yes, under section 16(2)(aa) and rule 36(4) |
| Shows eligible and ineligible credit separately | No | Yes: ITC available, ITC not available, and credit to be reversed |
| Effect of IMS actions | Continues as before | Accepted and deemed accepted records flow in; rejected records are for view only |
| Best use | Chasing suppliers, old-year reconciliations and notices | Filling Table 4 of GSTR-3B |
How did the rule change over the years?
From October 2019, rule 36(4) let you claim a little more than what suppliers had reported: 20 percent extra at first, then 10 percent from 1 January 2020 and 5 percent from 1 January 2021. That cushion ended on 1 January 2022, when clause (aa) was added to section 16(2). Since then, credit is allowed only to the extent it is communicated in GSTR-2B.
So when a notice for 2019-20 or 2020-21 compares your GSTR-3B with GSTR-2A, that comparison belongs to the old rule. CBIC Circular 193/05/2023-GST of 17 July 2023 explains how officers should treat those gaps for 1 April 2019 to 31 December 2021. For periods from January 2022, the test is 2B.
How does IMS change GSTR-2B?
Under the Invoice Management System, the 2B generated on the 14th is treated as a draft. It holds records you accepted or left without action, which count as accepted, plus rejected records shown for information only. If you act on records after the 14th, you recompute GSTR-2B before filing GSTR-3B. You can recompute as often as you like until GSTR-3B is filed. Our guide on IMS covers the actions.
One trap: if your previous month's GSTR-3B is still unfiled, the draft 2B is not generated on the 14th. File the old return first, then generate 2B from the IMS dashboard.
Some credit reaches 2B without passing through IMS: imports recorded through ICEGATE, documents from GSTR-5 and GSTR-6, and purchases under reverse charge. Reverse charge on imported services is not in 2B at all. You enter it yourself in GSTR-3B.
A worked example
Arjun sells phone accessories and files monthly. For September 2026, his purchase register shows GST of Rs 46,000 on five bills.
- Four suppliers filed GSTR-1 by 11 October. Their GST is Rs 40,600. It appears in his September GSTR-2B on 14 October.
- The fifth supplier, with GST of Rs 5,400, filed on 18 October. In GSTR-2A, the invoice shows under September. In GSTR-2B, it moves to October.
Arjun claims Rs 40,600 in his September GSTR-3B, filed on 20 October. He claims the Rs 5,400 in October, when it reaches that month's 2B. Had he claimed Rs 46,000 in September because the register or 2A showed it, Rs 5,400 would be credit not backed by 2B. Excess credit can be asked back with interest. It is a timing gap of one month, not a loss, so there is no reason to take the risk.
The mistake sellers usually make
The common mistake is claiming credit from the purchase register or from GSTR-2A. Both look complete, and both can be ahead of 2B. The portal compares the credit you claim with your 2B, and a large gap can bring an intimation in DRC-01C.
The reverse mistake is also costly. Some sellers never look at 2B and miss credit that is sitting there, for example GST on marketplace commission. Our article on ITC on marketplace commission shows where that credit comes from. Credit not claimed by 30 November after the year ends is lost for good, as explained in input tax credit conditions.
What should you do each month? Download 2B after the 14th, match it with your bills, act in IMS where needed, recompute if you changed anything, and claim what 2B shows. Then use 2A to see which suppliers filed late, and follow up with them.
