Section 44AB of the Income Tax Act mandates a tax audit by a Chartered Accountant for taxpayers whose business or professional income exceeds prescribed turnover limits — or who declare lower profit than the presumptive rate under Section 44AD/44ADA. The tax audit report (Forms 3CA/3CB and 3CD) must be filed by September 30 of the assessment year. Here is the complete guide.

Who Must Get a Tax Audit? — Section 44AB Applicability

  • Business taxpayer: If total sales/turnover/gross receipts exceed ₹1 crore in a financial year
  • Business taxpayer (enhanced limit — digital receipts): If total turnover is between ₹1 crore and ₹10 crore — tax audit is NOT required if cash receipts do not exceed 5% of total receipts AND cash payments do not exceed 5% of total payments. In such cases, effectively the limit becomes ₹10 crore.
  • Professional taxpayer: If gross receipts from profession exceed ₹50 lakh in a financial year
  • Presumptive income declaration: If a taxpayer covered by Section 44AD or 44ADA declares income lower than the prescribed percentage (8%/6% for business; 50% for profession) — mandatory tax audit regardless of turnover level
  • Covered by Section 44AE (transport): If profit declared is lower than prescribed per vehicle amount — mandatory audit

Tax Audit Report — Forms

  • Form 3CA: CA's audit report for taxpayers whose accounts are already audited under any other law (e.g., Companies Act audit)
  • Form 3CB: CA's audit report for other taxpayers (where accounts are not mandatorily audited under any other law)
  • Form 3CD: Statement of particulars — a detailed report with 44 clauses covering income, deductions, expenditures, related party transactions, loans, TDS compliance and more

Due Date

  • September 30 of the assessment year (30th September following the close of the financial year)
  • This is also the due date for ITR filing for audit cases (taxpayers required to get accounts audited)
  • Late filing penalty under Section 271B: 0.5% of turnover — maximum ₹1.5 lakh

Common Points in Form 3CD

  • Cash payments above ₹20,000 to single person per day (Section 40A(3) disallowance)
  • TDS compliance — defaults and disallowances under Section 40(a)(ia)
  • Loans/advances received in cash above ₹20,000 (Section 269SS)
  • Repayments of loans in cash above ₹20,000 (Section 269T)
