Tax Audit Under Section 44AB: Who It Applies To
A plain-language applicability guide to the Section 44AB tax audit for Indian SMEs: what it is, which businesses and professionals fall under it, why presumptive-scheme choices matter, and what to prepare.
11 min read
Short answer
A tax audit under Section 44AB is an examination of a taxpayer's accounts by a Chartered Accountant, resulting in a prescribed audit report that supports the income-tax return. It is not the same as a statutory company audit or a GST audit. Whether it applies to you depends on your taxpayer type, your turnover or gross receipts for the year, the proportion of cash in your receipts and payments, and whether you have opted into or out of a presumptive-taxation scheme. Do not assume a single turnover number decides it: the applicable limits, the cash-proportion condition, and the presumptive-scheme interaction each change the answer. Under the Income-tax Act, 2025 the governing provision is Section 63, the successor to Section 44AB of the Income-tax Act, 1961; confirm the current figures for your tax year against the official portal or your CA, because thresholds are periodically revised. Last reviewed: September 2026; re-review quarterly.

What a Section 44AB tax audit actually is
A tax audit is an independent examination of a business or profession's books of account by a Chartered Accountant, carried out so that the income declared in the income-tax return is supported by verified records. Under the Income-tax Act, 2025 the provision that governs it is Section 63, which carries forward the long-familiar tax audit of Section 44AB of the Income-tax Act, 1961. The examination produces a prescribed audit report and statement of particulars that the taxpayer files with, or alongside, the return.
Who can fall under it: businesses, professionals, and presumptive cases
Direct answer
Applicability turns on your category first, then your numbers. Businesses are tested on turnover or total sales for the year; independent professionals are tested on gross receipts; and taxpayers who have used a presumptive-taxation scheme are tested on a different, scheme-specific rule. Identify which of these you are before looking at any figure.
| Taxpayer category | What is measured | What can trigger a tax audit | Do not assume |
|---|---|---|---|
| Business (proprietor, firm, LLP, company) | Total sales, turnover, or gross receipts from the business for the year | Turnover crossing the applicable business limit for the year; a different, higher limit may apply where cash receipts and cash payments stay within a small prescribed proportion | That one fixed turnover number always applies, or that the cash-proportion relief is automatic |
| Profession (independent professional) | Gross receipts from the profession for the year | Gross receipts crossing the applicable professional limit for the year | That the business limit and the professional limit are the same |
| Presumptive business (opted into the business presumptive scheme) | Declared profit versus the scheme's presumptive rate, plus income above the basic exemption | Declaring profits lower than the scheme presumes while total income exceeds the basic exemption, or falling outside the scheme's conditions | That being in a presumptive scheme removes the audit question entirely |
| Presumptive profession (opted into the professional presumptive scheme) | Declared profit versus the scheme's presumptive rate for professions | Declaring profits lower than the scheme presumes while total income exceeds the basic exemption | That opting in this year binds every future year without consequence |
Why the cash proportion and the presumptive choice change the answer
The presumptive schemes add a second twist. A taxpayer who is eligible for and uses a presumptive scheme generally avoids a tax audit while declaring at or above the presumed rate. But declaring a lower profit than the scheme presumes, when total income crosses the basic exemption, can require maintaining books and getting a tax audit. Opting out of a presumptive scheme after using it can also carry a lock-in that affects several years. Treat the presumptive choice as a multi-year decision with an audit consequence, not a one-year convenience.
Work through applicability in order
- 01
Fix your taxpayer category for the year
Confirm whether the income is business or professional, and whether you file as an individual proprietor, firm, LLP, or company. A company may separately need a statutory audit under company law; that does not answer the tax-audit question.
- 02
Compute turnover or gross receipts on a defined basis
Measure total sales, turnover, or gross receipts for the full tax year on a consistent, documented basis. Decide the treatment of returns, discounts, taxes collected, and other items using current guidance rather than a rule of thumb, because the measurement basis affects whether a limit is crossed.
- 03
Check the cash proportion for businesses
For a business near the limit, work out the share of receipts and of payments made in cash. Whether the higher business threshold is available depends on both cash receipts and cash payments each staying within the prescribed small proportion of the respective totals under Section 63 of the Income-tax Act, 2025; a non-account-payee cheque or bank draft is treated as cash for this test. Confirm the current condition for your tax year with your CA or on the official portal.
- 04
Resolve the presumptive-scheme position
Establish whether you are eligible for, currently using, or exiting a presumptive scheme, and whether declared profit is at or below the presumed rate. This can independently trigger a tax audit even below the ordinary limits.
- 05
Confirm the conclusion and the deadlines
Once category, figures, cash proportion, and presumptive position are settled, confirm the applicability conclusion, the current audit-report format, and the due dates. Under the Income-tax Act, 2025, the tax-audit report must be furnished by a specified date ahead of the return due date, with the return due date for audited taxpayers falling later still. Confirm the current due dates for your tax year, which the department can extend, on the official portal or with your CA.
What to prepare if a tax audit applies
- Complete books of account: cash book, bank book, ledgers, sales and purchase registers, and journal, reconciled to bank statements.
- Sales, turnover, and gross-receipts working with the measurement basis documented and consistent across the year.
- A cash-receipts and cash-payments analysis where the higher business limit is being relied on.
- Fixed-asset register, depreciation working, and supporting invoices for capital purchases.
- Stock or inventory records and the valuation basis, where relevant to the business.
- Loan, deposit, and related-party payment records, since the audit report reports on several such particulars.
- TDS and TCS records that reconcile to challans and statements, and GST records where the business is registered.
- Prior-year return, prior audit report if any, and the current presumptive-scheme elections.
Escalate before a wrong applicability call becomes a filing problem
Getting applicability wrong has consequences in both directions. Missing an audit that was required can attract a penalty and complicate the return; commissioning an audit that was not required wastes cost and time. Because the answer depends on category, measurement basis, cash proportion, and the presumptive position together, borderline cases deserve professional review rather than a self-serve conclusion from a turnover figure.

This article is an educational applicability guide, not a conclusion that a tax audit does or does not apply to a specific taxpayer, nor a computation of any limit, penalty, or due date. The specific turnover and gross-receipts limits, the higher business limit and its cash-proportion condition, presumptive-scheme eligibility caps and lock-in rules, the audit-report format, and the due dates are set by the Income-tax Act, 2025, its Rules, and notifications for the relevant tax year and are periodically revised. This guide explains the factors under Section 63 of the Income-tax Act, 2025 that decide applicability, not their current numeric values; confirm the current figures for your tax year against official sources. Applicability depends on taxpayer category, entity type, measurement basis, cash proportion, and the presumptive position together. Confirm the current figures and obtain Chartered-Accountant advice for a specific business before acting.

Questions owners ask
Is a tax audit the same as a company's statutory audit?
No. A statutory audit under company law and an income-tax tax audit (Section 63 of the Income-tax Act, 2025, the successor to Section 44AB) are separate obligations with different triggers. A private company may need a statutory audit regardless of turnover and must still separately test whether the income-tax tax audit applies based on its turnover, cash proportion, and presumptive position. A GST audit or reconciliation is a third, distinct question.
Does using a presumptive-taxation scheme mean I never need a tax audit?
Not necessarily. A taxpayer who is eligible for and uses a presumptive scheme and declares at or above the presumed rate generally avoids a tax audit. But declaring a lower profit than the scheme presumes, when total income crosses the basic exemption, can require books and a tax audit, and exiting a scheme can carry a multi-year lock-in. Settle your presumptive position for the year before concluding, and confirm the current eligibility caps.
