Section 44AB of the Income-tax Act, 1961 mandates an independent audit of books of accounts by a practicing Chartered Accountant for commercial entities exceeding specified turnover thresholds. For businesses where aggregate cash receipts and cash payments do not exceed 5% of total transactions, the turnover threshold is elevated to ₹10 Crores (otherwise ₹1 Crore, or ₹2 Crores under Section 44AD). For professionals, the audit threshold is ₹50 Lakhs (or ₹75 Lakhs under Section 44ADA). Failure to complete and file the audit report by September 30 attracts a penalty under Section 271B of 0.5% of turnover up to ₹1,50,000.
Key Statutory Takeaways
- The ₹10 Crore threshold applies ONLY if both aggregate cash receipts and cash payments are <= 5% of total transactions.
- For traditional businesses exceeding 5% cash, the standard audit limit is ₹1 Crore (or ₹2 Crores if opting out of Section 44AD).
- Statutory due date for e-filing the Tax Audit Report (Form 3CA/3CB and 3CD) is September 30 of the assessment year.
- Form 3CA applies to entities already audited under any other law (e.g. Companies Act), while Form 3CB applies to unincorporated firms and proprietorships.
- Penalty for failing to get accounts audited under Section 271B is 0.5% of total turnover, subject to a statutory cap of ₹1,50,000.
