Important Update
| CBDT has extends due date for filing income tax audit report for FY 2024-25 from September 30, 2025 to October 31, 2025. |
Under Section 44AB of the Indian Income Tax Act, 1961, certain businesses and professionals are obligated to undergo a tax audit. This process involves a mandatory examination of their books of accounts to verify the correctness of their income tax filings. The eligibility thresholds for this audit are:
For Businesses
A turnover exceeding ₹1 crore during the financial year. This limit is raised to ₹10 crores if cash receipts and payments are within 5% of total receipts.
For Professionals
Gross receipts exceeding ₹50 lakhs in the financial year. In Budget 2023, this 50 lakh limit is increased to 75 lakh.
Purpose of Tax Audit
The core purpose of a tax audit is to verify compliance with tax laws and ensure the accurate reporting of taxable income, allowable deductions, and other required details.
Mandated by the Income Tax Department, this audit must be performed by a Chartered Accountant. The CA submits their findings electronically in prescribed forms (3CA, 3CB, and the comprehensive Form 3CD) by a strict deadline— September 30th, 2025, for the 2025-26 Assessment Year.
This system aids tax authorities in detecting errors and promoting compliance, while also offering taxpayers clarity and reducing the risk of penalties.
For the Assessment Year 2025-26, the statutory due date for submitting a tax audit report under Section 44AB is September 30, 2025. Consequently, the deadline for filing the corresponding Income Tax Return (ITR) for taxpayers requiring an audit is October 31, 2025.
