Tax Audit Under Section 44AB

Section 44AB of the Income Tax Act 1961 mandates that certain taxpayers get their accounts audited by a Chartered Accountant before filing their Income Tax Return. This audit ensures that the books of accounts are maintained correctly and that the income reported is accurate. Understanding whether you need a tax audit and meeting the deadline is critical to avoid penalties.

Who Needs a Tax Audit?

A tax audit under Section 44AB is mandatory for:

CategoryThreshold (FY 2024-25)
Business (cash turnover > 5%)Total sales/turnover exceeds ₹1 crore
Business (cash turnover ≤ 5%)Total sales/turnover exceeds ₹10 crore
ProfessionGross receipts exceed ₹50 lakh
Presumptive taxation (Sec 44AD)Taxpayer claims profits lower than the prescribed percentage
Presumptive taxation (Sec 44ADA)Professional claims profits lower than 50% of receipts

The ₹10 Crore Extended Threshold

The threshold was increased from ₹1 crore to ₹10 crore for businesses where:

  • Cash receipts do not exceed 5% of total receipts, AND
  • Cash payments do not exceed 5% of total payments

This effectively means that businesses conducting predominantly digital transactions can have turnover up to ₹10 crore without requiring a tax audit.

Tax Audit Forms

The Income Tax Return for audit cases must be filed by 31 October 2025. For transfer pricing cases, the extended deadline is 30 November 2025.
