GST Audit & Health Check India: Timelines and What Drives Them
How long GST Audit & Health Check India takes depends on a handful of things that are largely within your control. The questions below are the ones raised most often in practice; the full scope of the service is on the GST Audit & Health Check India page.
What triggers a departmental GST audit under Section 65?
Section 65 audits are typically risk-based, selected using the department's internal analytics on return data, industry risk profiles, refund claims, high-value ITC positions, or random selection as part of the department's annual audit programme. There is no single public formula for selection. The Commissioner (or an officer authorised by them) can direct an audit of any registered person for any period, with a minimum of 15 working days' advance notice under Section 65(3), and the audit is ordinarily required to be completed within 3 months of commencement, extendable by a further 6 months for reasons recorded in writing.
In practice: Large or sudden movements in ITC claims, high-value export/zero-rated refund claims, and industries the department has flagged for sector-wide scrutiny in a given year are the kinds of patterns that can attract scrutiny — though the department does not publish a definitive checklist.
What is the difference between Section 73 and Section 74 proceedings, and why does it matter so much?
Section 73 covers demands for tax not paid, short-paid, or ITC wrongly availed/utilised where there is no allegation of fraud, wilful misstatement, or suppression of facts. Section 74 covers the same categories of default but where fraud, wilful misstatement, or suppression is alleged. Under Section 73 the penalty is 10% of the tax due (subject to a statutory minimum), and nil where tax and interest are paid before, or within 30 days of, the show-cause notice. Section 74 penalty, by contrast, can reach 100% of the tax amount in the most severe cases where payment is not made early, alongside potential prosecution exposure in serious cases. Whether a case is pursued under Section 73 or Section 74 has a dramatic impact on the final liability.
In practice: A department can initially frame straightforward reconciliation errors as Section 74 cases — alleging suppression — when the facts genuinely support a Section 73 (non-fraud) characterisation. Contesting the framing, with documented evidence of good-faith error rather than concealment, is often the single highest-value thing a CA can do in a GST dispute. Note that the Finance (No. 2) Act, 2024 inserted a new Section 74A, which unifies the fraud and non-fraud demand mechanism into a single provision for periods from FY 2024-25 onwards, with a common time limit and a graded penalty structure depending on whether fraud/suppression is involved. Sections 73 and 74 continue to govern demands relating to periods up to FY 2023-24. We confirm which provision applies to your specific period as part of any engagement.
What is voluntary payment under Section 73(5), and why do you recommend it during a health check?
Section 73(5) allows a taxpayer to pay the tax and interest voluntarily, using Form DRC-03, before a show-cause notice is issued, and no penalty is then imposed; under Section 73(8), no penalty applies either where tax and interest are paid within 30 days of the notice. In fraud or suppression cases under Section 74, early payment instead reduces the penalty (to 15% of the tax before the notice and 25% within 30 days of it). For periods from FY 2024-25 the equivalent relief sits in Section 74A, where the post-notice window is 60 days. Paying voluntarily at this stage, before the department formally raises the demand, generally results in materially lower penalty exposure than waiting for a formal demand and contesting it. Where a health check identifies a genuine, quantifiable underpayment or ineligible ITC claim, voluntary DRC-03 payment is worth considering as a cost-effective resolution — subject always to your decision after the analysis is presented.
In practice: Voluntary payment is not an admission of guilt or wrongdoing in a punitive sense — it is a mechanism the law itself provides to encourage self-correction. We present the interest-and-penalty math for both paths (voluntary payment now versus wait-and-see) so the decision is made with full information.
What happens during a Section 65 departmental audit, practically speaking?
The department issues an intimation in Form ADT-01, giving at least 15 working days' notice. The audit is conducted either at your place of business or at the department's office, and can extend to reviewing books of account, GST returns, invoices, and any other records the officer considers relevant. On conclusion, the officer informs you of the findings, your rights and obligations, and the reasons for the findings via Form ADT-02. If the audit uncovers tax short-paid, ITC wrongly availed, or refund wrongly obtained, the department can initiate action under Section 73 or 74 (Section 74A for periods from FY 2024-25) depending on whether fraud/suppression is alleged.
In practice: The 15-working-day notice window is your opportunity, not just a formality — it is enough time to commission an expedited internal review, identify your own weak points before the officer does, and walk into the audit having already prepared explanations rather than discovering issues in real time in front of the auditor.
What records should we retain, and for how long, to support a GST audit if one is ever initiated?
Section 36 of the CGST Act requires every registered person to retain books of account and other records for a minimum of 72 months (6 years) from the due date of filing the annual return for the relevant year — longer if the matter is under appeal, revision, or any other proceeding, in which case records must be retained until one year after the final disposal of that proceeding. This includes invoices, e-way bills, input/output registers, and any records relied upon for ITC claims.
In practice: We recommend organising and digitising the retention set as part of the health check itself — a business that can retrieve a specific invoice or reconciliation working paper within minutes of an audit request is far better placed to respond than one that spends days searching physical files.
How does PNPC's GST health check help with fundraising or M&A due diligence?
Investors, acquirers, and lenders conducting financial or tax due diligence routinely request GST compliance evidence — reconciliation working papers, ITC eligibility support, and confirmation that no material undisclosed liability exists. A PNPC health check, performed proactively ahead of a transaction, gives you a documented, independently reviewed compliance position to present during diligence, rather than reacting to diligence questions with data assembled under deal-timeline pressure. Undisclosed GST exposure discovered during diligence is a common source of valuation adjustment (price chip) or indemnity negotiation in Indian M&A transactions.
In practice: Valuation discussions can move in the founder's favour when a clean, independently reviewed GST position could be presented upfront rather than the buyer's diligence team discovering gaps during their own review — the negotiating dynamic is very different depending on who surfaces the issue first.
Can the health check identify GST refunds we may be entitled to but have not claimed?
Yes — this is a secondary but valuable output of many health checks. Common unclaimed refund scenarios we identify include excess balance in the electronic cash ledger, inverted duty structure refunds (where input tax rate exceeds output tax rate), and unutilised ITC on zero-rated supplies under LUT that has not been claimed as a refund. Refund claims are time-barred two years from the relevant date under Section 54, so identifying an eligible-but-unclaimed refund late can mean losing the entitlement entirely.
In practice: Inverted duty structure refunds are particularly easy to miss because the business is otherwise fully GST-compliant — there is no error to flag, just an entitlement sitting unclaimed. We specifically screen for this pattern in every health check regardless of the original engagement trigger.
What is PNPC's approach if the health check reveals a serious, high-value discrepancy?
We do not simply flag a high-value finding and move on. For material discrepancies, we schedule a direct discussion with promoters or the CFO to walk through the specific facts, the legal basis for our conclusion, the realistic range of interest/penalty exposure under different resolution paths (voluntary payment, negotiated response to a future notice, or contest on the merits), and a recommended course of action. Serious findings involving potential fraud allegations or criminal exposure are flagged immediately, not held until the final report, given the time-sensitivity of the available remedies.
In practice: Time sensitivity matters enormously here — the difference between voluntary payment under Section 73(5) (or Section 74A for periods from FY 2024-25) and waiting for the department to find the same issue independently can be the difference between a manageable penalty and a materially larger one. We escalate significant findings the moment we identify them, not at the scheduled report delivery date.
