Most people missed the due date of filing income tax returns every year due to their busy schedules, lack of time, or for some other personal reasons. The due date for filing tax return is the date by which the return can be filed by the assess without any late fee or penalty. In this article we will answer the most frequently question asked by an individual “can i file my income tax return after the due date of filing”. Please remember our discussion will be limited to those individuals who are not requried to audit their books of account. This means its applicable to salaried individuals and those individuals whose incomes are not requried to be audited by a practicing chartered accountant.
The tax filing due date for Individuals whose books of accounts are not required to be audited for the financial year ending 31st march 2021 (FY 2020-2021) was 31st July 2021 which has been extended by CBDT till the 31st December 2021.
In case you have missed the due date, then do not worry, you still have time to file your tax return (ITR) up to 31st March 2022 for the financial year 2020-21. But the filing of such return will be treated as a belated return and not the original return that you could have filed before the due date.

If for the financial year ending 31st March 2021, you file your tax return between the due date, which is 31st December 2021, you will be liable to pay late fee and interest as applicable.
