This book is a comprehensive and updated treatise meticulously designed to address all aspects of tax auditing under Section 44AB of the Income-tax Act. Incorporating the latest amendments effected by the Finance Act 2025, this Edition provides in-depth guidance on every clause of Form No. 3CD. Special attention is devoted to the newly revised investment and turnover thresholds for MSMEs and how these affect reporting under Clause 22. The book offers auditing insights, compliance checklists, practical FAQs, and detailed explanations of statutory provisions. Its hallmark features include a structured analysis for each Form No. 3CD clause—covering what the clause mandates, possible pitfalls, relevant case law references, checklists, e-filing steps, and suggested audit documentation. In addition, multiple 'Tax Audit Reckoners' provide quick-reference tools for specific audits (e.g., cash transactions, sale of immovable property, share capital, and loans/deposits).
