# GST Audit Preparation: Checklist for Small Business Owners

By BillBabu Team · Published 15 May 2026 · Updated 8 October 2026 · Category: Business Growth

A GST audit doesn't have to be stressful. Use this checklist to keep records, reconcile data, and walk into the audit prepared.

## Documents to keep ready

Tax invoices and credit/debit notes for the audit period. Purchase invoices. Bank statements. GSTR filings (1, 3B, 9). E-way bills if applicable. Stock register. ITC ledger.

## Reconciliations to complete

GSTR-1 vs books of accounts. GSTR-3B vs GSTR-1. GSTR-2B vs purchase register. Bank statement vs invoice payments. Stock register vs physical count.

## Common audit issues

ITC claimed on bills not in GSTR-2B. Wrong place of supply on inter-state invoices. Missing HSN/SAC. Composition dealers issuing tax invoices. Non-disclosure of advances received.

## How to prepare ongoing

Reconcile monthly, not yearly. Use a billing app that tags ITC eligibility and flags missing GSTRs automatically.

## During the audit

Be cooperative, ask for time to retrieve old records, and never reply on the spot to ambiguous queries. A registered CA on call helps.
