Tax Audit & Penalties for AY 2023-24

Although AY 2023-24 is now history, the residual tax-audit and penalty exposure for taxpayers who under-reported, defaulted on filings or missed audits in that assessment year continues to play out in FY 2026-27. Reassessment notices under Section 148, penalty proceedings and prosecution remain active. This article revisits the tax audit framework as it stood for AY 2023-24 and outlines the consequences that taxpayers may still be dealing with today.

Who Was Required to Get a Tax Audit

• Businesses with turnover above ₹1 crore (or ₹10 crore where digital receipts and payments each exceeded 95%).
• Professionals with gross receipts above ₹50 lakh.
• Taxpayers opting out of the presumptive scheme under Section 44AD, 44ADA or 44AE within the lock-in period.
• Persons whose profits were lower than the presumptive percentage and income exceeded the basic exemption limit.

Forms and Due Dates for AY 2023-24

Audit reports were filed in Form 3CA/3CB and Form 3CD, with the original due date for furnishing the audit report being 30 September 2023 and the ITR due date being 31 October 2023 for audited taxpayers. Extensions, where notified by CBDT, applied uniformly.

Penalty Under Section 271B

Failure to get accounts audited or furnish the audit report by the due date attracts a penalty under Section 271B — the lower of 0.5% of total sales, turnover or gross receipts or ₹1,50,000. The penalty is not automatic; the Assessing Officer can drop proceedings where the taxpayer demonstrates a reasonable cause for the default.

Other Penalties Still Echoing from AY 2023-24

1. Section 234F — Late filing fee of up to ₹5,000 for belated returns.
2. Section 270A — 50% of tax under-reported and up to 200% for misreporting.
3. Section 234A/B/C — Interest on late filing and shortfall in advance tax.
4. Section 271AAC — 10% penalty on undisclosed income taxed under Section 115BBE.
5. Section 276CC — Prosecution for wilful failure to furnish return, in serious cases.

Reassessment Under Section 148

Even after the regular assessment window for AY 2023-24 has closed, the CBDT can reopen the case under Section 148 within the time limits prescribed by the Finance Act, where there is information suggesting income chargeable to tax has escaped assessment. Reassessment notices issued in FY 2025-26 and FY 2026-27 commonly relate to AY 2023-24, particularly where AIS data revealed mismatches.

How Taxpayers Are Responding in 2026

• Filing belated or updated returns under Section 139(8A) where time still permits, to limit exposure.
• Settling demands under prevailing CBDT amnesty windows where notified.
• Engaging in faceless assessment proceedings electronically through the e-filing portal.
• Approaching the CIT(A) or ITAT for relief on disputed additions.

Lessons for AY 2026-27

The AY 2023-24 experience underlines two lessons — get your audit done well before the due date, and reconcile every reported income with AIS. The CBDT's data-driven approach has only strengthened since then, so a clean audit trail and timely filing remain the best protection.

Updated Returns Under Section 139(8A)

The Finance Act introduced Section 139(8A) to allow taxpayers to file an updated return within an extended window from the end of the relevant assessment year, subject to additional tax. For AY 2023-24, taxpayers who realised mid-cycle that they had under-reported can still use this route within the prescribed time. The additional tax is steep, but it is materially cheaper than facing Section 148 reassessment and Section 270A penalty proceedings.

Defending a Scrutiny Notice

• Read the notice carefully — note the section invoked and the response deadline.
• Pull together the supporting books, contracts and bank statements.
• File a structured response on the faceless portal; avoid generic answers.
• Where the AO's view is contestable, prepare grounds for an appeal to CIT(A).
• Engage a tax counsel for cases that could escalate to ITAT or the High Court.

Lessons That Apply Today

The AY 2023-24 cycle is now playing out in reassessments and appeals, but its lessons apply directly to FY 2026-27 filers. Reconcile AIS thoroughly. Get the tax audit done well before the due date. Keep contemporaneous documentation. Respond to portal communications promptly. The faceless framework rewards organised, well-documented submissions and punishes casual or incomplete responses. The cost of a strong response is small; the cost of a weak one — interest, penalty, prosecution — can be very large.

Conclusion

Tax audit and penalty exposure from AY 2023-24 has not disappeared — it has merely matured into reassessments, demand notices and appellate proceedings now playing out in FY 2026-27. Taxpayers should respond promptly to notices, use updated-return windows where available, and apply the same discipline to current-year filings.
