Form 3CB is a crucial document used in India for tax purposes. It serves as an audit report generated under Section 44AB of the Income Tax Act, 1961. This form comes into play when a taxpayer, such as a business or a self-employed professional, isn't mandated by law to undergo a separate book of accounts audit.
Here's a scenario where Form 3CB becomes necessary: An individual proprietor, a partnership firm, or any other entity (apart from companies) has a yearly turnover exceeding Rs. 1 crore and hasn't opted for the presumptive taxation scheme. In such a case, even though an external audit isn't compulsory under any other law, the Income Tax Act necessitates the filing of Form 3CB. It's important to note that Form 3CD often accompanies Form 3CB, but we'll explore the distinction between these forms later.
