GST Audit: When is it Mandatory and How to Prepare

GST audit is a critical compliance requirement that businesses cannot afford to ignore. While the mandatory GST audit under Section 35(5) was withdrawn, many businesses still require reconciliation and certification by a Chartered Accountant or Cost Accountant.

Currently, GST audit is mandatory for businesses with an annual aggregate turnover exceeding Rs 5 crore. These taxpayers must file GSTR-9C, a reconciliation statement reconciling the annual return with the audited financial statements.

Preparation for GST audit should begin well before the due date. Maintain proper books of accounts, reconcile input tax credit with GSTR-2B, and ensure all sales and purchase invoices are accurately recorded in your accounting software.

Common errors flagged during GST audit include: mismatch between GSTR-1 and GSTR-3B, un-reconciled ITC, ineligible ITC claimed, and incorrect tax rate applied. Identifying and correcting these before filing saves you from show-cause notices and penalties.

The reconciliation process involves matching turnover as per books with turnover as per GSTR-1 and GSTR-3B. Any differences must be explained in the reconciliation statement. Similarly, ITC as per books must match ITC as per GSTR-2B.

Documentation is key. Keep all invoices, e-way bills, bank statements, and contracts organized. The auditor will need these to verify transactions. Digital record-keeping using GST-compliant software simplifies this process significantly.

Engaging a qualified CA early in the process ensures smooth audit filing. They can identify potential issues, help with corrections, and ensure the reconciliation statement is accurate. This proactive approach minimizes the risk of scrutiny and penalties from the tax department.
