Why GST Audit Matters

GST audits verify that your tax filings match your actual transactions. Common issues: mismatched invoices, wrong HSN codes, and unclaimed ITC.

Documents Needed

  • GSTR-1 and GSTR-3B filings for the audit period
  • Purchase invoices with GSTIN and HSN codes
  • Sales invoices with GSTIN and HSN codes
  • Input Tax Credit (ITC) reconciliation statement
  • E-way bills for inter-state transfers
  • Vendor GSTIN verification records

Common Issues

  • GSTIN mismatch between invoice and GSTR-2A
  • HSN code incorrect or missing
  • ITC claimed but vendor has not filed returns
  • E-way bill not generated for applicable transfers

Stay Compliant Year-Round

Reconcile GSTR-2A monthly. Verify vendor GSTIN at onboarding. Track HSN codes on every inventory item. Export GST reports for filing.
