GSTR-2B Guide — Auto-Drafted ITC Statement

GSTR-2B is a static, auto-generated statement available on the 14th of every month. It shows all Input Tax Credit (ITC) available to you based on your suppliers' GSTR-1/IFF filings, import data from ICEGATE, and ISD distributions. Since January 2022, GSTR-2B directly auto-populates GSTR-3B Table 4.

What is GSTR-2B?

GSTR-2B is a static (non-editable) statement that shows all ITC available and ineligible for a tax period. Unlike GSTR-2A (which changes as suppliers file), GSTR-2B is generated once on the 14th and remains static — making it reliable for ITC reconciliation.

GSTR-2A vs GSTR-2B: GSTR-2A is dynamic (updates in real-time as suppliers file GSTR-1). GSTR-2B is a monthly snapshot — it captures all GSTR-1 filings between the 12th of the previous month and the 11th of the current month. For ITC claims, always use GSTR-2B, not GSTR-2A.

Eligible vs Ineligible ITC: GSTR-2B categorizes credit into: (a) Available — ITC you can claim, (b) Not available — ITC that is ineligible per rules (blocked credits under Section 17(5), returns filed late, etc.). The portal auto-identifies ineligible credit based on GSTIN status and filing patterns.

GSTR-2B — Frequently Asked Questions

Can I claim ITC not appearing in GSTR-2B?

No. Since January 2022, Rule 36(4) mandates that ITC claim cannot exceed the amount in GSTR-2B plus 5% of eligible credit (for small invoices). Practically, you should only claim what GSTR-2B shows. If an invoice is missing, ask your supplier to file/amend their GSTR-1.

When is GSTR-2B generated?

GSTR-2B for a month is generated on the 14th of the following month. It captures supplier GSTR-1 filings from the 12th of the previous month to the 11th of the current month. For example, April 2026 GSTR-2B is generated on 14th May 2026.

What if GSTR-2B shows incorrect amounts?

Since GSTR-2B is auto-generated from supplier GSTR-1, errors must be corrected by the supplier via GSTR-1 amendment. Contact your supplier to file corrections. The corrected amount will appear in the subsequent month's GSTR-2B.

Is GSTR-2B different from GSTR-2A?

Yes. GSTR-2A is dynamic (updates real-time), GSTR-2B is static (monthly snapshot). GSTR-2B is the legally valid document for ITC claims since Jan 2022. GSTR-2A is informational only.
