Every return filed after the due date is treated as a belated return. A belated return can be filed three months before the expiry of the relevant assessment year. Similarly, a return filed to remove the error or omissions made in the original return is deemed a revised one. “A revised return can also be filed three months before the expiry of the relevant assessment year. However, the time limit provided for filing an updated return is 24 months from the end of the relevant assessment year,” says Rahul Singh, senior manager, Taxmann, tax and corporate advisor.
