Tax Audit Limit 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 tax audit limit is Rs 1 crore of business turnover, raised to Rs 10 crore where aggregate cash receipts and aggregate cash payments each stay within 5% of the respective totals, and Rs 50 lakh of gross receipts for a profession. The same three figures appear in section 44AB of the 1961 Act and in the section 63(1) table of the Income-tax Act, 2025.
The three figures
| Who | Tax audit limit | Condition |
|---|---|---|
| Business | Rs 1 crore | Total sales, turnover or gross receipts exceed the figure in the year |
| Business meeting both cash tests | Rs 10 crore | Cash receipts within 5% of total receipts and cash payments within 5% of total payments |
| Profession | Rs 50 lakh | Gross receipts in the profession exceed the figure; no cash relaxation |
A fourth trigger sits outside the turnover tests entirely: audit is also required where a person carries on a business or profession covered by the presumptive provisions and claims profits lower than the deemed profits. Turnover is irrelevant there — the tax audit limit that matters is the presumptive rate, not a rupee figure.
The 5% cash test, which is where cases are lost
The Rs 10 crore tax audit limit is not a general relaxation. It is conditional on two separate tests, and the statute requires both to pass:
- the aggregate of all amounts received, including for sales, turnover or gross receipts, in cash, does not exceed 5% of that total; and
- the aggregate of all payments made, including expenditure, in cash, does not exceed 5% of that total.
A payment or receipt by a cheque or bank draft that is not account payee is deemed to be in cash for this test. A bearer cheque, or one crossed but not marked account payee, counts against the 5%. This is the single most common reason a business that believed it was inside the Rs 10 crore tax audit limit turns out not to be.
Worked example — four businesses
| Business | Turnover | Cash position | Audit? |
|---|---|---|---|
| Trading firm A | Rs 4 crore | Receipts 2%, payments 3% | No — both tests passed, so the Rs 10 crore tax audit limit applies |
| Trading firm B | Rs 4 crore | Receipts 2%, payments 9% | Yes — the payment test failed, so the Rs 1 crore limit applies |
| Consultancy practice | Gross receipts Rs 62 lakh | All banked | Yes — above the Rs 50 lakh professional limit; no cash relaxation exists |
| Retailer declaring 5% against a presumptive rate of 6% | Rs 90 lakh | — | Yes — income claimed below the deemed profits |
Firm B is the instructive one. Its cash receipts were comfortably inside 5%, and a single failure on the payments side drops it from the Rs 10 crore tax audit limit to Rs 1 crore — a difference of an entire audit.
The presumptive shelter, and its edge
Where profits are declared at or above the presumptive rate, the audit provision does not apply, whatever the turnover — subject to the limits built into the presumptive provision itself. That is a genuine shelter and it is why many small businesses never encounter the tax audit limit at all.
The edge is sharp, though. Declaring below the deemed rate pulls the person into audit directly, regardless of how small the turnover is. A retailer with Rs 90 lakh of turnover declaring 5% against a deemed 6% is audited; the same retailer declaring 6% is not.
Where another law already requires an audit
If a person is required by a law other than the income-tax law to get accounts audited, it is sufficient compliance to get that audit done before the specified date and to furnish that report by the specified date along with the accountant's report in the prescribed form.
So the statutory audit does the audit work, but it does not remove the filing obligation. A company that crosses the tax audit limit and is audited under the Companies Act still files the tax audit report.
The same limits under the Income-tax Act, 2025
Section 63 of the Income-tax Act, 2025 is the successor to section 44AB and carries the heading "Tax Audit". The thresholds are unchanged in substance; what changes is the presentation — the conditions sit in a table in section 63(1) rather than in running text.
| Income-tax Act, 1961 | What it did | Income-tax Act, 2025 |
|---|---|---|
| 44AB(a) | Business turnover above Rs 1 crore | 63(1) — Table serial 1(a) |
| 44AB(a), proviso | Rs 10 crore where cash receipts and payments are within 5% | 63(1) — Table serial 1(b) |
| 44AB(b) | Professional gross receipts above Rs 50 lakh | 63(1) — Table serial 1(c) |
| 44AB(e) | Presumptive income declared lower than deemed profits | 63(1) — Table serial 2 |
| Explanation (ii) | Specified date one month before the return due date | 63(5)(a) |
| Second proviso | Audit under another law is sufficient compliance | 63(4) |
The Income-tax Act, 2025 takes effect from 1 April 2026 and applies from tax year 2026-27. The 1961 Act continues to govern every year up to 31 March 2026, including assessments, appeals and penalties, under the savings provision in section 536. For AY 2026-27 work, cite section 44AB; for the year now running, cite section 63.
Consequences of getting the tax audit limit wrong
Crossing the limit and not filing exposes the assessee to a penalty of 0.5% of total sales, turnover or gross receipts, or Rs 1,50,000, whichever is less. Because it is the lesser figure, the rupee cap governs from Rs 3 crore of turnover upward. The reasonable cause defence is available, and a bona fide interpretation of "turnover" based on written expert advice obtained before the specified date is among the instances that have been accepted — which is an argument for getting the advice in writing and dating it.
Checklist
- Compute the two cash ratios separately before relying on the Rs 10 crore tax audit limit; both must pass.
- Treat non-account-payee cheques and drafts as cash in those ratios.
- Do not apply any cash relaxation to a profession — the Rs 50 lakh figure has none.
- Check the presumptive position before concluding that a small business is outside audit.
- Where another law requires an audit, complete it before the specified date and file both reports.
- Where turnover is genuinely arguable, get the advice in writing and date it.
