Penalty explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
The penalty for not filing a tax audit report is 0.5% of total sales, turnover or gross receipts, or Rs 1,50,000, whichever is less. For AY 2026-27 the provision is section 271B of the Income-tax Act, 1961; from tax year 2026-27 it is section 446 of the Income-tax Act, 2025. Neither is automatic — reasonable cause removes it.
The provision, in its own words
Section 271B, headed "Failure to get accounts audited", provides that if any person fails to get the accounts audited in respect of any previous year or years relevant to an assessment year, or furnish a report of such audit as required under section 44AB, the Assessing Officer may direct payment, by way of penalty, of a sum equal to one-half per cent of total sales, turnover or gross receipts in business, or of gross receipts in profession, or Rs 1,50,000, whichever is less.
Three things follow straight from that wording, and each of them decides real cases.
- The penalty for not filing tax audit report covers two distinct defaults — not getting the audit done, and not furnishing the report. Either is enough.
- The amount is the lower of the percentage and the rupee figure. Rs 1,50,000 is a ceiling.
- The Assessing Officer "may direct". The provision is discretionary in form, and that discretion is exercised alongside section 273B.
Where the ceiling bites
0.5% of turnover equals Rs 1,50,000 at a turnover of exactly Rs 3 crore. Below that the penalty is the percentage; above it, the penalty is capped.
| Turnover | 0.5% of turnover | Penalty for not filing tax audit report |
|---|---|---|
| Rs 1.2 crore | Rs 60,000 | Rs 60,000 — the percentage is lower |
| Rs 3 crore | Rs 1,50,000 | Rs 1,50,000 — the two are equal |
| Rs 12 crore | Rs 6,00,000 | Rs 1,50,000 — the cap governs |
| Rs 40 crore | Rs 20,00,000 | Rs 1,50,000 — the cap governs |
A business with Rs 40 crore of turnover faces the same maximum as one with Rs 3 crore. For larger assessees, the meaningful consequence of a late report is not the penalty for not filing tax audit report at all — it is the knock-on effect on the return, on disclosure, and on the scrutiny profile. Do not let the modest cap set the internal urgency.
The defence against a penalty for not filing tax audit report
Section 273B provides that no penalty is imposable under section 271B if the assessee proves that there was reasonable cause for the failure. Paragraph 8.2 of the ICAI Guidance Note records this expressly, and it also records the part that decides outcomes: the onus of proving reasonable cause is on the assessee.
That allocation is the whole game. Reasonable cause is not presumed from circumstances. It has to be established with evidence, and the evidence is far easier to assemble on the day than two years later in penalty proceedings.
Instances that have defeated a penalty for not filing tax audit report
Paragraph 8.3 of the Guidance Note lists instances accepted by Tribunals and Courts as reasonable cause. What follows pairs each with the document that actually proves it.
| Instance | What to keep on file |
|---|---|
| Resignation of the tax auditor and consequent delay | The resignation letter, its date, and the date the successor was appointed |
| Bona fide interpretation of "turnover" on expert advice | The written advice, dated before the specified date |
| Death or physical inability of the partner in charge of accounts | Medical or death records, and evidence of that partner's role |
| Labour problems — strike or lock out for a long period | Notices, correspondence, and the period covered |
| Loss of accounts by fire, theft and the like | FIR, fire brigade or insurance records |
| Non-availability of accounts on account of seizure | The seizure panchnama and the date records were returned |
| Natural calamities, commotion | Contemporaneous evidence of the event and its effect |
| Resignation of the accountant and consequent non-cooperation | The resignation and evidence of the handover failure |
| Failure of the official e-filing portal | Timestamped screenshots and a grievance ticket number |
A screenshot taken on the specified date with the timestamp visible, plus a grievance reference raised the same day, is worth far more than an assertion months later that the portal was down. Make capturing that evidence part of the filing-day routine whenever an upload fails — it costs two minutes on the day and cannot be recreated afterwards.
What is not on the list
The list is of instances that have been accepted; it is neither exhaustive nor a menu. Two themes run through it. Every accepted instance involves something outside the assessee's control, and every one of them is capable of documentary proof.
Measured against that, some familiar excuses fall away. Ordinary pressure of work is not outside anyone's control. An expectation that the date would be extended is not evidence of anything. A client who did not respond to reminders is closer to the auditor's file-management problem than to a reasonable cause, unless the non-cooperation is itself documented.
Framing matters less than proof. The same facts advanced as "the client was slow" and as "the accountant resigned on 4 August and the successor received the records on 19 September, per the attached correspondence" are the same events — but only the second has any prospect of displacing a penalty for not filing tax audit report, because only the second can be put in front of the Assessing Officer as evidence.
The same penalty under the Income-tax Act, 2025
Section 446 is the successor. It is short and mechanical, and the amount is identical: the lesser of 0.5% of total sales, turnover or gross receipts in business, or gross receipts in profession, and Rs 1,50,000. The two-limb default structure carries over — failure to get accounts audited, and failure to furnish the report as required under section 63.
| Income-tax Act, 1961 | What it did | Income-tax Act, 2025 |
|---|---|---|
| 271B | Penalty for failure to get accounts audited | 446 |
| 44AB | Tax audit requirement | 63 |
| 44AA | Books of account | 62 |
| 271A | Penalty for failure to keep books | 441 |
| 273B | Reasonable cause defence | 470 |
| 275 | Limitation for penalty | 472 |
The trigger is the same in structure too. Section 63(1) requires the audit to be completed before the specified date and section 63(3) requires the report to be furnished by it, with section 63(5)(a) defining that date as one month prior to the section 263(1) return due date. Missing it is what exposes a taxpayer to the penalty for not filing tax audit report under section 446.
Related penalties worth knowing about
- Section 441 (formerly 271A) — failure to keep, maintain or retain books under section 62. A separate default from the audit one, and both can arise on the same facts.
- Section 447 — failure to furnish the transfer pricing accountant's report under section 172.
- Section 472 (formerly 275) — the limitation bar for imposing penalties.
Practical position
- Treat the upload and the acceptance as two separate events; furnishing completes on acceptance, and the penalty for not filing tax audit report attaches to non-furnishing.
- Where a client's turnover position is genuinely arguable, get written advice and date it before the specified date. It is one of the few pre-emptive steps the accepted instances actually reward.
- Document any disruption on the day it happens, not when the notice arrives.
- Do not treat the Rs 1,50,000 cap as the measure of the risk for a large assessee.
- For AY 2026-27 cite 271B and 273B; for tax year 2026-27 onwards cite 446 and 470.
