GST Audit Checklist

Reconcile returns, books and ITC before a GST audit so mismatches and exposures are fixed in advance.

GST AUDIT CHECKLIST

Prepare for a departmental, internal or GSTR-9C-based GST review with this reconciliation checklist.

Registration & Basics

  • ☐ GSTIN details verified for each registered state
  • ☐ Principal and additional places of business updated
  • ☐ HSN / SAC codes correctly mapped to supplies
  • ☐ Correct tax rates applied on all invoices

Returns & Reconciliation

  • ☐ GSTR-1 vs books turnover reconciled
  • ☐ GSTR-3B vs GSTR-1 tax liability reconciled
  • ☐ GSTR-3B vs books output tax reconciled
  • ☐ Annual turnover vs GSTR-9 reconciled
  • ☐ GSTR-9C reconciliation statement prepared, if applicable

Input Tax Credit (ITC)

  • ☐ ITC claimed vs GSTR-2B matched invoice-wise
  • ☐ Ineligible / blocked ITC (Section 17(5)) reversed
  • ☐ ITC reversal for exempt supplies (Rule 42/43) computed
  • ☐ Vendor payment within 180 days verified for ITC

Invoicing & Documents

  • ☐ Tax invoices contain all mandatory particulars
  • ☐ E-invoice (IRN) generated where turnover threshold applies
  • ☐ E-way bills matched with outward supplies
  • ☐ Credit / debit notes properly recorded and reported

Payments & Records

  • ☐ RCM liability identified and paid
  • ☐ Interest and late fees on delayed payments computed
  • ☐ Electronic cash / credit ledger balances tallied
  • ☐ Records preserved for prescribed retention period

Note: Document each reconciliation difference with reasons; voluntary payment through DRC-03 before audit reduces interest and penalty exposure.
