Understanding tax audit applicability under Section 44AB of the Income-tax Act, 1961 is essential for businesses and professionals before finalising their books and income-tax returns for FY 2025-26 (AY 2026-27).
The requirement to obtain a tax audit depends primarily on the nature of the activity, turnover or gross receipts, cash transaction conditions, and whether the taxpayer is covered by any presumptive taxation provisions.
Tax Audit Applicability for Business
For taxpayers carrying on a business, the general threshold for tax audit is ₹1 crore of turnover or gross receipts.
However, the law provides a higher threshold of ₹10 crore where the aggregate amount of cash receipts and cash payments does not exceed the prescribed 5% limit.
1. Turnover up to ₹1 Crore
Where the business turnover or gross receipts do not exceed ₹1 crore, tax audit under the normal turnover-based provision of Section 44AB is generally not mandatory, subject to other applicable audit conditions.
2. Turnover above ₹1 Crore but up to ₹10 Crore
A business may fall within the higher ₹10 crore tax-audit threshold if the prescribed cash transaction condition is satisfied.
Broadly, the aggregate of:
- Cash receipts should not exceed 5% of total receipts; and
- Cash payments should not exceed 5% of total payments.
Where these conditions are satisfied, the ₹10 crore threshold can apply.
3. Where the 5% Cash Condition Is Not Satisfied
If the prescribed cash transaction condition is not fulfilled, the enhanced ₹10 crore threshold is not available. In such circumstances, the normal ₹1 crore threshold becomes relevant for determining tax-audit applicability.
Tax Audit Applicability for Professionals
For persons carrying on a profession, the general threshold under Section 44AB is ₹50 lakh of gross receipts.
Therefore:
- Gross receipts up to ₹50 lakh: Tax audit is generally not required under the normal threshold.
- Gross receipts exceeding ₹50 lakh: Tax audit may become applicable, subject to the specific provisions and other conditions of Section 44AB.
Professionals should also examine whether they have opted for or are otherwise covered by the presumptive taxation provisions applicable to their profession.
Section 44ADA and the ₹75 Lakh Threshold
Section 44ADA provides a presumptive taxation framework for specified professionals.
The presumptive taxation threshold can extend from ₹50 lakh to ₹75 lakh where cash receipts do not exceed 5% of total gross receipts, subject to the statutory conditions.
Importantly, the ₹75 lakh figure should not be confused with a general tax-audit threshold for every professional. Section 44AB and Section 44ADA operate through specific statutory conditions, and the taxpayer’s actual circumstances must be examined before determining whether tax audit is required.
Important Tax Audit Due Dates for FY 2025-26
For FY 2025-26 (AY 2026-27), taxpayers should keep the following dates in mind:
| Compliance | Due Date |
|---|---|
| Tax Audit Report | 30 September 2026 |
| Income-Tax Return for Tax-Audit Cases | 31 October 2026 |
These dates should be checked against any subsequent statutory extension or notification issued by the Central Board of Direct Taxes (CBDT).
Forms Used for Tax Audit
For taxpayers subject to tax audit, the applicable audit documentation generally includes:
- Form 3CA – where accounts are required to be audited under another law;
- Form 3CB – where accounts are not required to be audited under any other law; and
- Form 3CD – statement of particulars accompanying the tax audit report.
Key Points Practitioners Should Verify
Tax-audit applicability should not be determined merely by looking at turnover or gross receipts. Before reaching a conclusion, practitioners should examine:
- Nature of the taxpayer’s activity — business or profession.
- Total turnover or gross receipts.
- Cash receipts and cash payments vis-à-vis the prescribed 5% conditions.
- Applicability of presumptive taxation provisions.
- Whether the taxpayer has declared income in accordance with the relevant presumptive taxation provisions.
- Any other specific circumstances that may trigger audit under Section 44AB.
- Whether CBDT has subsequently extended or modified the applicable compliance deadlines.
Conclusion
The tax audit provisions for FY 2025-26 (AY 2026-27) require careful evaluation rather than a simple turnover-based calculation.
For businesses, the distinction between the ₹1 crore and ₹10 crore thresholds is particularly important, while professionals should carefully consider the ₹50 lakh threshold and the conditions applicable to Section 44ADA, including the higher ₹75 lakh presumptive-taxation limit where the prescribed cash-receipt condition is satisfied.
A proper review of turnover, gross receipts, cash transactions, presumptive taxation provisions and other statutory conditions can help taxpayers avoid incorrect conclusions regarding tax-audit applicability and related filing requirements.
