### Overview of Section 44AB Tax Audit
Section 44AB of the Income Tax Act, 1961 mandates that individuals, partnership firms, LLPs, and corporate entities exceeding statutory turnover or gross receipts limits must get their accounts audited by a practicing Chartered Accountant.
Key Turnover Limits & Statutory Conditions
1. **General Business Threshold (₹1 Crore):** Any business whose total sales, turnover, or gross receipts exceed ₹1 Crore in a financial year is subject to statutory tax audit. 2. **Enhanced Digital Limit (₹10 Crores):** If aggregate cash receipts and aggregate cash payments do not exceed 5% of total receipts/payments (i.e. 95%+ transactions executed via banking channels, NEFT, RTGS, UPI, or cards), the tax audit turnover threshold is raised to ₹10 Crores. 3. **Professional Threshold (₹50 Lakhs / ₹75 Lakhs):** Professionals (engineers, doctors, advocates, CAs, architects, IT consultants) with gross receipts exceeding ₹50 Lakhs (or ₹75 Lakhs under digital receipt conditions) require statutory audit.
Presumptive Taxation Interplay (Section 44AD & 44ADA)
* **Section 44AD (Small Businesses):** Small businesses with turnover up to ₹2 Crores (₹3 Crores if digital receipts exceed 95%) can declare profit at 6% (digital) or 8% (non-digital). Declaring profit below these statutory percentages when total income exceeds basic exemption forces mandatory tax audit under Section 44AB(e). * **Section 44ADA (Specified Professionals):** Professionals with gross receipts up to ₹50 Lakhs (₹75 Lakhs if digital) can declare 50% as taxable net profit. Declaring lower profits requires maintaining formal books of accounts under Section 44AA and undergoing Section 44AB audit.
Critical Form 3CD Reporting Clauses
Tax Audit documentation comprises:
* **Form 3CA / 3CB:** The primary audit certificate issued by the Chartered Accountant. Form 3CA is used when accounts are audited under any other law (e.g. Companies Act), while Form 3CB is used for standalone tax audits. * **Form 3CD:** A 44-clause statement detailing disallowances u/s 40(a)(ia), statutory dues payments u/s 43B, related party payments u/s 40A(2)(b), and MSME payment disallowances under Section 43B(h).
Penalty for Non-Compliance (Section 271B)
Failing to submit the tax audit report by the due date (30th September) can attract a statutory penalty under Section 271B equal to **0.5% of total turnover/gross receipts**, up to a maximum of **₹1,500,000**.
