Goods and Services Tax audits play a critical role in preventing errors in GST filings and in responding to government notices. However, if you haven’t prepared well for them, it can be a stressful experience.
With evolving compliance requirements and increased scrutiny from tax authorities, even minor documentation gaps can lead to penalties or notices. Understanding how to prepare for a GST audit and having a clear checklist in place can help small business owners stay compliant, reduce risks and face audits with confidence.
In this blog, we will share the checklist you need to have to prepare for your GST audit.
What is the role of GST returns in internal audits?
GST returns are the primary records auditors rely on to assess the tax compliance of your business. Under the GST frame you file your returns such as GSTR-1, GSTR-3B and GSTR-2B to record outward supplies, summary return and auto-populated inward supplies based on the supplier’s filing.
During an audit, these returns are carefully reviewed to check whether the figures reported are accurate and consistent across filings. If there are mismatches, such as differences may indicate inconsistency and non-compliance.
Auditing Checklist for Different GST Returns
Below is the detailed checklist for each GST return:
GSTR-1
- Review whether all outward supply invoices have been fully and correctly reported, including accurate GSTIN and tax details.
- Examine transactions covered under the reverse charge mechanism and interstate supplies to unregistered persons for proper disclosure.
- Assess the reporting of zero-rated supplies and deemed exports to ensure they are classified in line with GST provisions.
- Check that debit notes, credit notes, refund vouchers and advances are appropriately recorded and adjusted in the return.
- Verify the HSN-wise summary of outward supplies and confirm that reporting aligns with the prescribed turnover thresholds.
- Perform sample checks of invoices to ensure compliance with GST invoice rules, including correct place of supply details.
- Leverage GST software to improve data accuracy, track changes and simplify reconciliation during the audit.
GSTR-3B
- Reconcile outward supply values reported in GSTR-3B with invoice records and figures declared in GSTR-1.
- Check whether debit notes, credit notes and advances are correctly disclosed and reflected in the appropriate tables.
- Examine purchase transactions along with imports and exempt or nil-rated supplies.
- Verify that the input tax credit has been claimed only on eligible invoices and aligns with GSTR-2B.
- Review transactions liable to reverse charge to ensure correct tax treatment and reporting.
- Match the tax liability declared under CGST, SGST and IGST with challans and payment records.
- Cross-verify return summaries with books of accounts or ERP data to detect and address variances at an early stage.
Reconciliations you should complete before a GST audit
Reconciliation is a critical part of your GST audit preparation, as it helps you identify and resolve discrepancies. As part of your reconciliation process, you should:
- Match outward supplies reported in GSTR-1 with the tax liability declared in GSTR-3B.
- Reconcile the input tax credit claimed in GSTR-3B with the eligible credits reflected in GSTR-2B and your purchase register.
- Align GST returns with your books of accounts and financial statements to ensure overall consistency.
- Identify timing differences, missing invoices or amendment-related mismatches and rectify them promptly.
Common GST Audit Issues and How to Avoid Them
During a GST audit, certain issues commonly arise due to gaps in review processes or delayed compliance actions. Being aware of these issues allows you to take preventive steps well in advance.
Some common GST audit issues you may encounter include:
- Mismatches between GSTR-1, GSTR-3B and GSTR-2B caused by incomplete reporting or delayed amendments.
- Incorrect or excess input tax credit claims, particularly on ineligible expenses.
- Errors in classification of supplies, incorrect tax rates or wrong place of supply reporting.
- Missed or delayed reporting of debit notes, credit notes and advances.
You can avoid these issues by conducting periodic internal reviews, maintaining proper documentation and performing regular reconciliations. Leveraging GST accounting software further strengthens your compliance framework by improving accuracy, tracking changes and reducing the risk of penalties during audits.
