When should I perform ITC reconciliation?

ITC reconciliation should be done monthly — before filing GSTR-3B, after GSTR-2B is generated (available on the 14th). It should also be done annually before filing GSTR-9. Regular reconciliation prevents ITC mismatches from accumulating into large demands during GST audits.

What happens if ITC in books exceeds GSTR-2B?

If ITC claimed in GSTR-3B exceeds what appears in GSTR-2B, the excess is considered ineligible under Section 16(2)(aa). The department can issue ASMT-10 or DRC-01 demanding reversal with 18% interest from the date of excess claim. To avoid this, contact your suppliers to file their GSTR-1 or reverse the excess ITC proactively via DRC-03.

Can I claim ITC that is missing from GSTR-2B?

No — under the current law, ITC is restricted to what appears in GSTR-2B. However, the department has clarified that if a supplier later files their return and the invoice appears in a future GSTR-2B, you can claim it in that month's GSTR-3B, subject to the time limit under Section 16(4).

What is ITC Reconciliation?

Input Tax Credit (ITC) Reconciliation is the process of matching ITC claimed in GSTR-3B against ITC available in GSTR-2B, and reconciling both with your purchase register. The Finance Act 2022 inserted Section 16(2)(aa) making GSTR-2B matching mandatory — ITC cannot be claimed unless the invoice appears in GSTR-2B.

Common ITC Reconciliation Issues & Fixes

Excess ITC in GSTR-3B vs GSTR-2B

Reverse the excess in the next return. Pay interest at 24% p.a. under Section 50(3) on excess ITC claimed.

ITC Lapsed Due to Time Bar

ITC not claimed by November 30 of the next FY or annual return, whichever is earlier, is permanently lapsed under Section 16(4).

Rule 86A Credit Block

GST officers can block ITC if they suspect fraud. Regular supplier status checks help identify risky suppliers early.

Proportionate Reversal (Rule 42/43)

ITC on inputs used for both taxable and exempt supplies must be reversed proportionately. All reversals must be in GSTR-3B Table 4B.

ITC Reconciliation Best Practices

✅ Reconcile monthly — monthly mismatches compound and become difficult to resolve at year end.

✅ Verify supplier GSTIN status — inactive GSTINs mean blocked ITC regardless of payment made.

✅ Match invoice-by-invoice — aggregate matching misses amount and GSTIN discrepancies.

✅ Track pending ITC — follow up with suppliers who haven't filed GSTR-1 to protect your credits.

✅ Use DRC-03 proactively — voluntary payment before department action avoids penalties under Section 74.

✅ Document reversals — all ITC reversals must be reflected in GSTR-3B Table 4B with supporting workings.
