GST Audit Services

Q: What is a GST audit and is it mandatory?

A GST audit examines books, returns, and records of a GST-registered taxpayer. The mandatory CA audit under Section 35(5) was abolished from FY 2020-21. Taxpayers above ₹5 crore turnover still file GSTR-9C. Departmental audits under Section 65 can be conducted at any time.

Q: What is the difference between GSTR-9 and GSTR-9C?

GSTR-9 is the annual return summarising outward/inward supplies, ITC, and taxes paid. GSTR-9C is a reconciliation statement comparing GSTR-9 figures with audited financial statements. Taxpayers with aggregate annual turnover exceeding ₹5 crore must file GSTR-9C.

Q: What are the most common GST compliance errors found during a GST audit?

Common errors include: ineligible ITC claims, GSTR-1 and GSTR-3B mismatches, incorrect HSN classification, failure to reverse ITC on supplier defaults or non-payment within 180 days, and place of supply errors affecting CGST/SGST vs IGST.

Q: What triggers a departmental GST audit under Section 65?

Triggers include significant GSTR reconciliation mismatches, large ITC claims, sector risk profiling, intelligence inputs, or risk-based selection. High ITC-to-turnover ratios and frequent return amendments increase audit risk.

Q: How far back can a GST audit cover?

Under Sections 73 and 74 of the CGST Act, demands can be raised for up to three years (five years in fraud cases) from the due date of the annual return for the relevant financial year.

Independent GST Audit & Reconciliation to Ensure Compliance, Accuracy, and Risk-Free Filings

A GST audit is an examination of the returns, accounts, and records of a registered taxpayer to verify the correctness of turnover declared, taxes paid, refunds claimed, and input tax credit (ITC) availed. It ensures that a business's GST filings accurately reflect its actual transactions and are consistent with its books of accounts.

With GST scrutiny by tax authorities increasing significantly, businesses face growing exposure to notices, demands, and penalties arising from ITC mismatches, GSTR reconciliation gaps, and incorrect classification. Our GST audit services provide a structured, independent review that identifies and resolves these issues before they attract departmental attention. This service connects with our income tax audit, audit and assurance overview, and VAT annual audit services for businesses with multi-tax compliance obligations.

Frequently Asked Questions

What is a GST audit and is it mandatory?

A GST audit is an examination of the books of accounts, returns, and records of a GST-registered taxpayer to verify the accuracy of tax compliance. The mandatory GST audit by a Chartered Accountant under Section 35(5) of the CGST Act was abolished with effect from FY 2020-21. However, taxpayers with turnover above ₹5 crore are still required to file GSTR-9C, a self-certified reconciliation statement. Departmental GST audits under Section 65 by GST officers can be conducted at any time.

What is the difference between GSTR-9 and GSTR-9C?

GSTR-9 is the annual return that every registered taxpayer must file, summarising all outward and inward supplies, ITC availed, and taxes paid during the financial year. GSTR-9C is a reconciliation statement comparing the figures in GSTR-9 with the audited annual financial statements. Taxpayers with aggregate annual turnover exceeding ₹5 crore must file GSTR-9C, which is now self-certified rather than certified by a CA.

What are the most common GST compliance errors found during a GST audit?

Common errors include: ITC claimed on ineligible expenses such as personal use items, blocked credits under Section 17(5), or goods and services not used in the course of business; mismatches between GSTR-1 and GSTR-3B due to timing differences; incorrect HSN classification leading to wrong tax rates; failure to reverse ITC on supplier defaults or non-payment within 180 days; and errors in place of supply determination affecting the correct tax head (CGST/SGST vs IGST).

What triggers a departmental GST audit under Section 65?

Departmental GST audits may be triggered by significant GSTR reconciliation mismatches, large or unusual ITC claims, sector-specific risk profiling by the GST department, intelligence inputs, or selection through the department's risk-based audit selection system. Businesses with high ITC-to-turnover ratios, frequent amendments to returns, or mismatches between GSTR-1 and GSTR-3B are at higher risk of selection.

How far back can a GST audit cover?

Under Section 73 and 74 of the CGST Act, GST authorities can issue demand notices for up to three years (extended to five years in cases of fraud) from the due date of the annual return for the relevant financial year. A proactive GST audit for prior open years is therefore strongly advisable, as errors discovered by the department after this period may attract significantly higher interest and penalties than self-correction.
