What is Tax Audit?
Mandatory audit under Section 44AB of Income Tax Act
Tax Audit is a mandatory examination and verification of the books of accounts of a taxpayer by a qualified Chartered Accountant, as required under Section 44AB of the Income Tax Act, 1961. The objective is to ensure that the taxpayer has properly maintained books of accounts, complied with tax laws, and correctly computed taxable income and tax liability.
The Chartered Accountant prepares an audit report in prescribed forms (Form 3CA-3CD or 3CB-3CD) which contains observations, discrepancies, and confirmations about the taxpayer's financial statements and tax computations. This report must be filed electronically on the Income Tax e-filing portal before the due date to avoid penalties.
