Section 44AB of the Income-tax Act, 1961 mandates the audit of accounts for certain categories of taxpayers to ensure the accuracy and reliability of financial statements. This section applies to individuals and entities engaged in business or profession whose total sales, turnover, or gross receipts exceed specified thresholds. For businesses, the threshold is Rs. 1 crore, while for professionals, it is Rs. 50 lakh. The audit must be conducted by a chartered accountant, and the audit report must be furnished in the prescribed form by the due date of filing the income tax return. This provision is significant as it ensures transparency and compliance with tax laws, reducing the scope for tax evasion. The statutory test involves verifying the correctness of the books of accounts and ensuring compliance with accounting standards. The burden of proof lies with the taxpayer to demonstrate adherence to these requirements. In practice, this section plays a crucial role in maintaining the integrity of financial reporting and tax compliance.
