Could I file income tax return after 4 years?

 No, Typically Not: The standard deadline to file a belated income tax return is within two years from the end of the relevant assessment year.

Missed Deadline: After 4 years, you usually cannot file a return, and missed filing may result in penalties or interest.

 Condonation Request: In rare cases, you may request the Condonation of Delay from the Income Tax Department, but approval is not guaranteed.

Refund Claims: If you are expecting a refund, it may not be processed after the 2-year limit unless exceptional circumstances are approved.
