As responsible citizens, we all know that it is very important to file income tax returns (ITR) on time. This time around, the deadline to file ITR for the financial year 2020-2021 has been extended to December 31, 2021. In fact, the due date for ITR filing for the assessment year 2020-2021 has been extended twice—first from July 31, 2021, to September 30, 2021, and then to December 31, 2021.
