GSTR-2B Reconciliation — Stop Losing Input Tax Credit

GSTR-2A vs GSTR-2B: What Actually Governs Credit Eligibility

GSTR-2A is a dynamic statement that updates continuously as suppliers file late returns. GSTR-2B is a static monthly auto-drafted statement generated on the 14th of every month. Under current GST law, only GSTR-2B governs input tax credit (ITC) eligibility for a given return period.

The Four Primary Mismatch Categories

During monthly reconciliation, purchase registers are checked against GSTR-2B across four categories:

• Matched Credit: Invoice present in books and GSTR-2B — safe to claim.
• Unclaimed Credit: Invoice in GSTR-2B but missing in books — eligible credit at risk of expiry.
• Ineligible / Reversal Risk: Invoice in books but missing in GSTR-2B — claiming will trigger ASMT-10 notice.
• Supplier Mismatches: Invoice uploaded under wrong GSTIN or tax head (IGST vs CGST/SGST).

How Monthly Reconciliation Prevents ASMT-10 Department Notices

Departmental scrutiny under Section 61 relies heavily on automated variance reports comparing GSTR-3B credit claimed against GSTR-2B. Running automated full-population reconciliation each month ensures that discrepancies are flagged and corrected before returns are filed — eliminating exposure to ASMT-10 notices and interest penalties.
