Section 44AB Tax Audit 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.
Section 44AB requires a tax audit where business turnover exceeds Rs 1 crore — raised to Rs 10 crore where cash receipts and cash payments are each within 5% — or where professional gross receipts exceed Rs 50 lakh. Four further clauses catch presumptive-scheme cases.
This is based on the ICAI Guidance Note on Tax Audit under Section 44AB of the Income-tax Act, 1961 (Revised 2026), the Eleventh Edition, incorporating the Finance Act, 2026. The Guidance Note's own Preface records that, with the Income-tax Act, 2025 in force from 1 April 2026, this is the concluding edition under the 1961 Act. It therefore governs the last 44AB audit cycle. For later years the audit runs on section 63 of the Income-tax Act, 2025 and rule 47 of the Income-tax Rules, 2026, where the report is Form No. 26, not Forms 3CA/3CB/3CD.
The five trigger clauses
| Clause | Who | Trigger |
|---|---|---|
| 44AB(a) | Person carrying on business | Total sales, turnover or gross receipts exceed Rs 1 crore in any previous year — see the 5% proviso below |
| 44AB(b) | Person carrying on profession | Gross receipts exceed Rs 50 lakh in any previous year |
| 44AB(c) | Business under section 44AE, 44BB or 44BBB | Claims income lower than the deemed profits |
| 44AB(d) | Profession under section 44ADA | Claims income lower than the deemed profits and income exceeds the maximum amount not chargeable to tax |
| 44AB(e) | Business where section 44AD(4) applies | Income exceeds the maximum amount not chargeable to tax |
The Rs 10 crore proviso and the 5% test
The first proviso to section 44AB(a) substitutes "ten crore rupees" for "one crore rupees" where both of these hold:
- (a) the aggregate of all amounts received, including amounts received for sales, turnover or gross receipts during the previous year, in cash, does not exceed 5% of that amount; and
- (b) the aggregate of all payments made, including amounts incurred for expenditure, in cash, does not exceed 5% of that payment.
The second proviso is easy to miss and expensive to get wrong: a payment or receipt by a cheque drawn on a bank, or by a bank draft, which is not account payee, is deemed to be in cash for this test. A business that considers itself fully banked because it does not handle currency can still fail the 5% test if it issues or receives bearer or crossed-but-not-account-payee instruments. Both limbs must be satisfied — receipts and payments.
Who is outside section 44AB
The provisos exclude:
- a person who declares profits and gains in accordance with section 44AD(1) or section 44ADA(1) — that is, a person who actually adopts the presumptive rate rather than claiming lower; and
- a person who derives income of the nature referred to in section 44B or section 44BBA, on and from 1 April 1985 or the date the relevant section came into force, whichever is later.
The third proviso — audited under another law
Where the person is required by or under any other law to get accounts audited, it is sufficient compliance if he gets those accounts audited under that law before the specified date, furnishes that report by that date, and furnishes a further report by an accountant in the prescribed form.
The Guidance Note draws a practical consequence at paragraph 3.5: a company or LLP should select the third proviso to section 44AB as the applicable provision in clause 8 of Form 3CD, not section 44AB(a), because their accounts are audited under another law. The same care is needed for co-operative societies and trusts audited under their own statutes.
Special cases the Guidance Note settles
Exempt income does not mean exempt from audit
Paragraph 6.1 records that neither section 44AB nor any other provision exempts a person whose income is exempt. Paragraph 6.2 notes the CBDT view that where income is exempt under section 10 — for example sections 10(21), 10(23A), 10(23B), 10(23BB), 10(23C) and 10(26AAA) — or under section 11, the exemption does not extend to maintaining books under section 44AA or getting accounts audited under section 44AB.
A co-operative society enjoying deduction under section 80P must likewise get its accounts audited if business turnover exceeds the prescribed limit.
Income below the taxable limit is irrelevant
Paragraph 6.3 is explicit: the object of the audit is to assist the Assessing Officer in computing total income. So even if total income is below the taxable limit under the relevant Finance Act, the audit is required if any section 44AB condition is met.
Non-residents
Paragraph 6.4: section 44AB makes no distinction between a resident and a non-resident. A non-resident is liable if turnover, sales or gross receipts exceed the prescribed limits. The audit is, however, confined to the Indian operations, since the non-resident is chargeable in India only on income accruing, arising or received in India.
Interest and remuneration from a firm is not a partner's turnover
Paragraph 5.20 addresses a recurring question. Under section 28(v), interest, salary, bonus, commission or remuneration due to a partner from the firm is chargeable under "Profits and gains of business or profession". But it cannot be treated as the partner's gross receipts or turnover — the partner is not carrying on business independently; the firm is. The Guidance Note cites Perizad Zorabian Irani v. PCIT, Mumbai, WP No. 1333/2021, Bombay High Court, dated 9 March 2022.
The constitutional footing
The vires of section 44AB were upheld in T.D. Venkata Rao v. Union of India [1999] 237 ITR 315 (SC), where the Court observed that chartered accountants "by reason of their training have special aptitude in the matter of audits" and form a class by themselves. Section 44AB was inserted by section 11 of the Finance Act, 1984 with effect from 1 April 1985, for assessment year 1985-86 onwards.
Worked example
A trading firm has turnover of Rs 6.4 crore for the previous year. Cash receipts are Rs 24 lakh against total receipts of Rs 6.6 crore; cash payments are Rs 41 lakh against total payments of Rs 6.2 crore. It also issued Rs 18 lakh of crossed cheques that were not marked account payee.
| Test | Computation | Result |
|---|---|---|
| Cash receipts | 24 / 660 = 3.64% | Within 5% |
| Cash payments, ignoring the cheques | 41 / 620 = 6.61% | Already above 5% |
| Cash payments, with the non-account-payee cheques deemed cash | (41 + 18) / 620 = 9.52% | Further above 5% |
The payments limb fails, so the Rs 10 crore proviso is unavailable and the ordinary Rs 1 crore threshold applies. With turnover of Rs 6.4 crore, the firm is liable to tax audit.
Compliance checklist
- Identify which of the five clauses applies — more than one can.
- Run the 5% test on both receipts and payments, and include non-account-payee cheques and drafts as cash.
- For a company, LLP, co-operative society or trust audited under another law, select the third proviso in clause 8, not 44AB(a).
- Do not exclude an entity because its income is exempt or below the taxable limit.
- For a non-resident, scope the audit to Indian operations.
- Exclude a partner's interest and remuneration from the firm when testing the partner's own turnover.
Common mistakes
- Applying Rs 10 crore on the receipts test alone. Both limbs must pass.
- Treating all cheque transactions as non-cash. Non-account-payee instruments count as cash.
- Selecting 44AB(a) in clause 8 for a company or LLP.
- Skipping the audit for a section 11 or section 10 entity.
- Adding a partner's remuneration to the partner's turnover.
