One updates in real-time, one is legally binding for ITC claims. Learn the critical differences and which one to use. 6 min read Updated 16 September 2026 Ahopez Innovations Team GSTR-2AGSTR-2BITCReconciliation GSTR-2A and GSTR-2B are both auto-drafted purchase statements on the GST portal. GSTR-2A is a live, changing view of supplier filings. GSTR-2B is a fixed monthly snapshot — and the one that legally governs your ITC claim. ## Side-by-Side Comparison FeatureGSTR-2AGSTR-2BNatureDynamic (changes continuously)Static (fixed once generated)GeneratedUpdated whenever supplier files14th of every monthCoversAll invoices as they appearInvoices filed up to 13th of monthEditable?No — read onlyNo — read onlyUsed for ITC claim?No (reference only)Yes — legally binding under Rule 36(4)Auto-populates GSTR-3B?NoYes (from Oct 2022)Available fromAlwaysAugust 2020 onwards Important Since October 2022, GSTR-3B auto-populates ITC strictly from GSTR-2B (100% matching). Claiming ITC beyond GSTR-2B and utilizing it attracts 18% interest under amended Section 50(3). Under Section 16(4), the final cutoff to claim any missed ITC for a financial year is 30th November of the following year (or filing GSTR-9, whichever is earlier). ## Common Reasons for Mismatch - Supplier filed GSTR-1 after the 13th — will appear in next month's GSTR-2B - Supplier entered wrong buyer GSTIN on the invoice - Invoice amount or date mismatch between your books and supplier's filing - Supplier hasn't filed GSTR-1 at all for the period - Invoice tagged to wrong tax period by supplier Pro Tip Always ask your suppliers to file GSTR-1 by the 11th of each month. Late supplier filing = delayed ITC = higher cash outflow for you. ## File GST returns with zero manual work Kallapotti generates GSTR-1-ready data, auto-calculates HSN codes, and tracks ITC — all from your daily billing.
