Tax Audit Under Section 44AB – A Practical Training Guide

Summary: Understanding tax audit under Section 44AB of the Income-tax Act, 1961, is essential for tax professionals. A tax audit is mandated when business turnover exceeds ₹1 crore (or ₹10 crore if cash transactions are limited to 5%) or professional receipts exceed ₹50 lakhs. Specific presumptive taxation schemes exist under Sections 44AD, 44ADA, and 44AE. Key forms for reporting include Form 3CA/3CB and Form 3CD, which details various clauses like disallowances, TDS compliance, and GST reconciliation. Turnover computation includes sales, commissions, and profits/losses from F&O, while excluding capital asset sales and agricultural income. The filing process involves the client assigning the form to the Chartered Accountant, who then uploads it using a Digital Signature Certificate, followed by client approval. Proper audit documentation, including fixed asset registers and TDS trackers, is crucial. Penalties under Section 271B for non-filing can be waived under Section 273B for reasonable cause. Ethical practices, communication with previous auditors, and maintaining independence are also vital. Special attention should be given to GST turnover mismatches, TDS defaults, unsecured loans, misclassified capital assets, unexplained credits, taxability of gifts, MSME reporting, and timely PF/ESI contributions.

“We believe in making tax compliance not just a duty but a skill. One such cornerstone in the tax profession is the Tax Audit under Section 44AB of the Income-tax Act, 1961. For aspiring Chartered Accountants and audit trainees, understanding tax audit is not just about form-filling—it’s about owning the audit process with confidence, clarity, and compliance.“

Special Points:

1.Mismatch Between GST Turnover/ITC and Books

• Clause 44 now requires GST reconciliation.
• Cross-verify Form GSTR-3B, GSTR-1, and books turnover.
• If any mismatch arises (like GST shown in returns but not in books), report it in Notes/Observations.

• Prepare Some Important Reconciliation (GSTR-1 vs GSTR-3B) (GSTR-1 vs BOOKS) (GSTR-3B VS GSTR- 2B) (GSTR-2B VS Books) GSTR-1 VS E-Way Bills VS E-Invoice)

2. TDS Default Tracker (Clause 34)

Many ignore late payments or non-deductions of TDS:

• Track TDS defaults from TRACES compliance reports.
• Report interest paid/due under Sections 201(1A), 40(a)(ia).
• Use Form 26AS + TDS ledgers to reconcile.

3. Unsecured Loans & Deposits (Sec 269SS/269T)

• Check all cash loans accepted or repaid ≥ ₹20,000.
• Report such violations explicitly under Clause 31.
• If any such transaction is detected, penalty under Sec 271D/271E may be attracted.

4. Capital Assets Misclassified as Expenses

• Check for large one-time expenses—may be capital in nature.
• Eg: Office renovation, computers, machinery.
• Reclassify in audit observations if wrongly booked.

5. Unexplained Credits (Section 68)

• If sudden large cash deposits or credits in books appear:
  • Ask for supporting explanations (loan agreements, KYC).
  • Report unusual or suspicious entries in Notes to Audit Report (not in Form 3CD but in annexure).

6. Taxability of Gifts and Share Premium (Section 56(2))

• Check whether any share capital/premium received falls under:
  • Section 56(2)(viib) (for unlisted companies)
  • Gifts exceeding ₹50,000 from non-relatives
• Covered under Clause 36B (recent addition).

7. MSME Reporting (Clause 22)

• Many assessees ignore whether vendors fall under MSME.
• If payment is delayed beyond 15/45 days, and vendor is registered MSME, no deduction allowed under Section 43B(h).
• Obtain MSME self-declaration from vendors.

8. Employee PF/ESI Contributions

• Check due dates under PF/ESI Acts.
• If paid late, disallow under Section 36(1)(va) even if paid before return filing.

9. Foreign Remittance Reporting

• Any remittance abroad must be backed by Form 15CA/CB.
• Maintain supporting documentation.

10.Transfer Pricing Alerts

• If international/domestic related party transactions > ₹20 crore, check for Form 3CEB requirement.
