ITC RECONCILIATION WORKING PAPER — GSTR-2A / 2B VS BOOKS

Entity: ___ · GSTIN: ___ · Financial year ended: ___

Purpose: reconcile input tax credit reflected in GSTR-2A/2B against ITC recorded in the books of account, vendor by vendor, and investigate every difference before ITC is claimed or carried forward.

For each difference: confirm whether the vendor has filed their GSTR-1/GSTR-3B for the period (credit only reflects in 2B once filed), whether the invoice was reported against the correct GSTIN, and whether the credit was availed in the books before or after it appeared in 2B — under the current matching framework, ITC generally cannot be claimed in the return until it reflects in GSTR-2B.

Common questions

FAQs.

Should ITC reconciliation use GSTR-2A or GSTR-2B?
GSTR-2B is the primary reference for claiming ITC — it is a static, once-generated-per-period statement that determines eligible credit for that specific return period. GSTR-2A is dynamic (it keeps updating as vendors file or amend returns), so it is useful for investigating why a credit is missing from 2B, but the actual ITC claim should be tested against 2B.
What if a vendor has not filed their GSTR-1 for the period?
The corresponding ITC will not appear in GSTR-2B, and under the current matching-based ITC framework, that credit generally cannot be claimed until the vendor files. The recipient should follow up with the vendor and hold the credit rather than claim it unmatched, since claiming unmatched ITC risks a demand notice with interest.
Can ITC be claimed in the books before it reflects in GSTR-2B?
It can be recorded in the books when the invoice is received (for accounting purposes), but it should not be claimed in the GST return until it reflects in GSTR-2B for a corresponding period — this is exactly the gap this working paper is built to surface and track until resolved.
