Introduction
A tax audit in India is a detailed examination of the books of accounts of a taxpayer to ensure that they comply with the provisions of the Income Tax Act, 1961. It is conducted under Section 44AB of the Act.

- The aggregate of all cash receipts does not exceed 5% of total receipts.
- The aggregate of all cash payments does not exceed 5% of total payments.
2. For Professionals:
