GSTR-2A
GSTR-2A is a dynamic, auto-populated statement of a recipient's inward supplies that updates continuously as suppliers file or amend their returns.
GSTR-2A is the dynamic, continuously-updating record of your inward supplies, drawn from suppliers' filings. Unlike the static GSTR-2B, it keeps changing as suppliers file late or amend. Since January 2022, ITC is claimed on the basis of GSTR-2B, not 2A, so 2A is now mainly a tracing and historical tool.
GSTR-2A pre-dates GSTR-2B and mirrors, in real time, whatever your suppliers report in their GSTR-1, GSTR-5, GSTR-6, GSTR-7 and GSTR-8. Because it never freezes, the same period can show different figures on different days — which is precisely why it was replaced by the static GSTR-2B as the reference for credit.
For reconciliation, 2A still earns its keep. When an invoice is missing from a given month's 2B, 2A helps you see whether the supplier filed it late, in a different period, or not at all — evidence you need before invoking Rule 37A or writing to the vendor. Both statements rest on Rule 60 of the CGST Rules. Keeping the two side by side also helps defend a claim during departmental scrutiny, where officers compare 2A, 2B and 3B.
The Recoup angle: Recoup reads 2A alongside 2B so a credit that slipped into the wrong month is traced, not lost.
