Professional Misconduct 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.
A question of professional misconduct in connection with tax audit is answered under the Chartered Accountants Act, 1949, where ICAI's disciplinary jurisdiction prevails — and ICAI's Taxation Audits Quality Review Board can refer serious reporting non-compliance for disciplinary proceedings.
From the ICAI Guidance Note on Tax Audit (Revised 2026), the Eleventh and, by ICAI's own statement, concluding edition under the Income-tax Act, 1961. The disciplinary framework and the TAQRB's remit come from ICAI, so they continue for audits under section 63 of the Income-tax Act, 2025 and Form No. 26 under rule 47 of the Income-tax Rules, 2026.
Where the jurisdiction lies
Paragraph 14.1 is short and unambiguous. When any question relating to professional misconduct in connection with tax audit arises:
- the tax auditor would be liable under the Chartered Accountants Act, 1949; and
- ICAI's disciplinary jurisdiction will prevail in this regard.
This mirrors paragraph 9.10, which says the same about liability generally: the tax auditor is answerable to the Council of the Institute, and in all matters concerning tax audit ICAI's disciplinary jurisdiction prevails. The Assessing Officer's route, under paragraph 9.11, is to refer a case of suspected gross negligence to ICAI — not to adjudicate professional misconduct himself.
The Taxation Audits Quality Review Board
ICAI has constituted the TAQRB with a sole aim: to review
- any report prescribed under the Income-tax Act, 1961 and the Rules framed thereunder; and
- any report prescribed under the indirect tax laws including GST law,
which are certified by a chartered accountant, with a view to determining, to the extent possible, compliance with:
- the reporting requirements prescribed under the respective Acts and related Rules; and
- pronouncements and guidance notes issued by ICAI in respect of the same.
Where the TAQRB finds material or serious non-compliance in the tax audit report, appropriate action, including referring the case for disciplinary proceedings, may be initiated.
The TAQRB is not a complaints body. It reviews filed reports against the reporting requirements, which means an engagement can come under scrutiny without any client, department or third party raising an issue. The practical consequence is that a clause reported thinly, or a "NIL" entered where a qualification was warranted, is visible on the face of the report itself — and professional misconduct exposure follows from what the report says, not only from what went wrong in the audit.
The TAQRB observations printed in this edition
The Revised 2026 edition does something new: it prints, in italics under the relevant clauses, the instances of irregularities, deficiencies and common errors the TAQRB noted while reviewing tax audit reports. The Guidance Note is careful about their status:
"'TAQRB observations' do not form part of this Guidance Note, are not exhaustive and should not be construed as authoritative guidance or as prescribing any additional reporting requirements beyond those contained in the Income-tax Act, 1961, the Income-tax Rules, 1962 or this Guidance Note."
Their inclusion is intended only to highlight deficiencies and reporting issues noticed and to avoid recurrence in tax audit reporting. They are purely illustrative and informational, and are set in italics solely to distinguish them from the main body.
The detailed treatment is in the TAQRB publication "Study on compliances in reporting in tax audit report", published on ICAI's resource site.
What the observations reveal about common failures
The observations printed under clauses 1 to 8a give the flavour of what the reviewers actually find:
| Clause | TAQRB observation |
|---|---|
| Clause 2 | The address reported differed from the address in the Annual Report and/or the records maintained with the Ministry of Corporate Affairs |
| Clause 4 | Registrations under other indirect tax laws referred to in the CARO Report were not fully reported; and registration numbers did not match the PAN reported in the form, without any corresponding qualification in Form No. 3CA or 3CB |
| Clause 8 | Companies audited under the Companies Act, 2013 incorrectly selected clause (a) instead of the option "Audited under any other law" required by the third proviso to section 44AB |
None of these is a difficult technical judgement. All three are cross-checks against documents the auditor already holds — the annual report, the CARO report, the PAN. That is the pattern the reviews expose, and it is the pattern most likely to convert a reporting slip into a professional misconduct question.
How the disciplinary exposure is actually managed
- Documentation. Paragraph 13.3 requires notes on the work done and by whom, explanations received and by whom, decisions taken, judicial pronouncements relied on, and certificates and management letters. SA 230 supplies the standard.
- Qualification rather than silence. Paragraph 19.3(d) is explicit that where particulars are furnished in part, piecemeal or incomplete, the auditor should not withhold the audit report but should qualify in Para 3 of Form 3CA or Para 5 of Form 3CB.
- Stating both viewpoints. Paragraph 19.3(b): where the auditor and the assessee differ on any information, the auditor may state both viewpoints and the relevant information, to enable the tax authority to decide.
- UDIN. Paragraph 9.37 makes UDIN the link between a filed report and a real member, and it is validated online against ICAI's systems.
Worked example
| What the report says | Exposure |
|---|---|
| Clause 4 lists one GSTIN; the CARO report of the same company refers to three State registrations; no qualification anywhere | A TAQRB-type finding on its face. The remedy was a one-line qualification, not more audit work |
| Clause 8 shows "44AB(a)" for a company audited under the Companies Act, 2013 | Incorrect; the third proviso option should have been selected |
| Clause 22 reported "NIL" with no working paper on MSME creditor identification | A "true and correct" assertion with nothing behind it, and no representation under SA 580 |
| Auditor disagreed with the assessee on clause 21(b) and recorded both positions in Para 5 of Form 3CB | Compliant with paragraph 19.3(b); no professional misconduct question arises from a disclosed difference |
Audit checklist
- Treat the report as a document that will be read by a reviewer with no access to your file.
- Cross-check clause 2 against the annual report and MCA records.
- Cross-check clause 4 against the CARO report and the PAN.
- Cross-check clause 8 against whether the accounts were audited under any other law.
- Qualify rather than withhold where information is incomplete.
- Record both viewpoints where you differ from the assessee.
- Read the TAQRB observations under each clause as a list of what reviewers look at, while remembering they add no new reporting requirement.
Common mistakes
- Treating the italicised TAQRB observations as new requirements — or ignoring them entirely.
- Reporting "NIL" on a clause without evidence that the answer is nil.
- Withholding the report instead of qualifying it.
- Assuming professional misconduct only arises when a client complains.
- Leaving inconsistencies between the tax audit report and the annual report or CARO report unexplained.
