Please refer to the correct answer for your question as below:

A provision has been made by the CBDT for an application to the CIT, in terms of S. 119(2)(b), for condonation of delay in filing return of income by the due date or the extended due date. Such an application is possible in cases of refund of taxes paid or deducted, and is subject to fulfilment of other conditions.

It is common to come across cases of persons who have failed to file a return of income within the time stipulated u/s.139, and that the Income-tax Department has also not issued any notice u/s.148 in such cases. It is also common that in some of such cases, excess tax is paid and a refund is otherwise due.

Thus, you may make an application to CIT.
