Understanding GSTR-2B
What is GSTR-2B? GSTR-2B is a static statement generated by the GST portal on the 11th of every month (or 12th if the 11th is a holiday). It contains details of all inward supplies for a taxpayer for a given tax period. It serves as the authoritative basis for claiming Input Tax Credit (ITC).
How it differs from GSTR-2A: GSTR-2A was dynamic and changed as suppliers filed returns. GSTR-2B is static—once generated, it doesn't change. GSTR-2B has replaced GSTR-2A as the official statement for ITC claims.
Why it matters: Reconciliation ensures that the ITC you claim matches the GSTR-2B statement. Mismatches can lead to ITC denial, notices, and penalties. Regular reconciliation also helps identify supplier non-compliance early.
Generation timeline: GSTR-2B is generated on the 11th of every month. For example, April's GSTR-2B is generated on May 11th. It covers the previous month's transactions.
