This guide explains tax audit applicability, turnover thresholds, deadlines, penalties, and the key provisions of Section 44AB in simple terms.
What Is Section 44AB?
If you are wondering what is section 44ab, it is the provision of the Income-tax Act, 1961 that requires certain persons carrying on business or profession to get their accounts audited and furnish the prescribed audit report.

However, the rules also contain special conditions for taxpayers using presumptive taxation schemes and for businesses with a very low level of cash transactions.
The purpose of an audit under section 44ab is not simply to check turnover. The tax auditor examines the books and relevant records and reports prescribed information to the Income Tax Department in the applicable tax audit forms.

| Cash Transactions | Cash receipts and payments can affect the applicable tax audit threshold for businesses. | 5% threshold | Both cash receipts and cash payments must remain within the prescribed 5% limits to qualify for the higher ₹10 crore threshold, subject to applicable rules. |

The exact result depends on the section involved, turnover or receipts, and the taxpayer’s filing history.
What is the Tax Audit Limit for AY 2025-26?
The tax audit limit for AY 2025-26 relates to the financial year 2024-25. For businesses, the standard threshold was ₹1 crore, with the enhanced ₹10 crore threshold available where cash receipts and cash payments each remained within the prescribed 5% conditions. For specified professionals, the relevant gross-receipt threshold was ₹50 lakh.
It is important to remember that the tax audit limit for AY 2025-26 should not automatically be treated as the applicable limit for every future assessment year. Tax laws and compliance requirements can change through amendments, notifications and circulars.
What is the Report Due Date for Income Tax Audit?
The income tax audit report due date is generally earlier than the due date for filing the income tax return in audit cases.
Under the normal statutory timeline, the tax audit report is generally required to be furnished by 30 September of the relevant assessment year, while the income tax return for taxpayers covered by the audit requirement is generally due by 31 October, subject to the applicable provisions and any extension announced by the government.
For AY 2025-26, the tax audit report deadline was subsequently extended from 30 September 2025 to 31 October 2025. This was a year-specific extension and should not be assumed to apply automatically to other assessment years.
Taxpayers should therefore always verify the latest notification or circular before relying on a deadline.
Tax Audit Due Date Extension: What Does It Mean?
A tax audit due date extension means the government extends the deadline for furnishing the audit report for a particular assessment year or category of taxpayers.
For example, for AY 2025-26, the audit report deadline was extended to 31 October 2025. Such extensions are generally announced through official government notifications or circulars.
An extension of the audit report deadline does not necessarily mean that every related compliance deadline is automatically extended. Taxpayers should separately verify the due date for filing the income tax return and other applicable compliances.
What is the Penalty for Late Tax Audit Report?
Failure to get accounts audited or failure to furnish the required audit report within the prescribed time may attract a penalty under Section 271B.
The penalty can be 0.5% of total sales, turnover or gross receipts, subject to a maximum of ₹1.50 lakh.
However, the penalty is not automatic in every case. Under the law, a taxpayer may avoid the penalty if they can establish that there was reasonable cause for the failure. Each case depends on its facts and circumstances.
What are the Documents and Records Required for Tax Audit Under Section 44AB?
If you are covered by Section 44AB, it is advisable to start the process well before the deadline. Keep the following records ready:
- Books of account and ledgers
- Sales and purchase records
- Bank statements
- Cash book
- GST records and returns
- Details of loans and advances
- Fixed asset records
- TDS and TCS information
- Details of expenses and statutory payments
- Details of cash receipts and cash payments
Maintaining accurate records throughout the year can make the audit process smoother and reduce the risk of errors or last-minute compliance issues.
Key takeaways
Understanding tax audit requirements is essential for businesses and professionals crossing the prescribed turnover or receipt thresholds. Section 44AB covers specific categories of taxpayers and includes different thresholds and conditions depending on the nature of business, profession, cash transactions and presumptive taxation.
The key takeaway is simple: do not wait until the filing deadline to determine your audit applicability. Check your turnover, gross receipts, cash transactions and presumptive taxation position in advance. Also, verify the latest official due dates because a tax audit due date extension may be announced for a particular assessment year.
For AY 2025-26, the audit report deadline was extended to 31 October 2025, but taxpayers should always check the latest applicable rules for the assessment year in question.
