Section 44AB of the Income Tax Act requires certain businesses and professionals to get their accounts audited by a Chartered Accountant (CA) and submit an audit report — the Tax Audit Report — along with their Income Tax Return. A tax audit is separate from a statutory audit under the Companies Act. Here is the complete guide to Section 44AB.

Who Needs a Tax Audit?

  • Business — Turnover above ₹1 crore: Any person carrying on a business where total sales/turnover exceeds ₹1 crore in a financial year
  • Business — Turnover above ₹10 crore (digital transactions): If cash receipts and cash payments are each 5% or less of total receipts/payments — threshold enhanced to ₹10 crore
  • Profession — Gross receipts above ₹50 lakh: Persons carrying on a profession (as specified) with gross receipts exceeding ₹50 lakh
  • Presumptive scheme opt-out: A person eligible for presumptive taxation (44AD/44ADA) who declares income below the prescribed rate — must get a tax audit done
  • Business loss cases: A person with business loss who wants to carry it forward must get audited if turnover exceeds the threshold

Tax Audit Forms

  • Form 3CA: When the accounts of the taxpayer are already audited under any other law (e.g., company under Companies Act, co-operative society under Co-operative Societies Act). The CA gives a statement that the accounts have already been audited.
  • Form 3CB: When accounts are audited only under Section 44AB (no other mandatory audit). The CA certifies the accounts and prepares the audit report.
  • Form 3CD: Statement of particulars — a detailed prescribed form with 44 clauses covering: method of accounting, details of tax, TDS compliance, depreciation, loans above ₹20,000, cash transactions above limits, deductions claimed, etc. Must be attached to both 3CA and 3CB.

Due Date

  • Tax audit report must be uploaded on the IT portal by 30 September (before the ITR filing due date of 31 October for audit cases)
  • The CA uploads the report digitally; the taxpayer accepts it on the portal

Penalty for Non-Compliance

  • Failure to get tax audit done or failure to submit report: Penalty of 0.5% of turnover/gross receipts — subject to a maximum of ₹1,50,000
  • Reasonable cause exception available (bonafide failure)
Form 3CD has 44 clauses — errors in any attract scrutiny and audit proceedings: Many taxpayers underestimate the complexity of the tax audit report. SPOTON's CAs handle complete tax audit and Form 3CD preparation for businesses and professionals in Kerala. Call +91 99614 11863.
