For filing returns, the Income Tax Department has set out different forms. These forms are filed by the taxpayers as per the category that they fall under and the source of their income. There are multiple criteria that decide eligibility of a taxpayer to file a particular ITR form. Form ITR-4 is used for filing Income Tax Return by those taxpayers who have opted for the presumptive income scheme under Sections 44AD, 44ADA and 44AE of the Income Tax Act, 1961. This is, however, subject to the business turnover limit of INR 2 crores, exceeding which the taxpayer would be required to file ITR-3. Presumptive Taxation scheme is a scheme that exempts the small taxpayers from maintenance of books of accounts.
