Itr rejected

If assesse fails to sent acknowledgement within 120 days than the return is invalid. So now you have to file return again, you can not file revised return as original return is not a valid.

If there is any problem in filing the return again contact the e filing helpline.

 

In FAQ (Q2 of Q relating to CPC) its mentioned that in such a case revised return should be filed but it will be treated as original return

Once you have complied with S.139(1) there is nothing in S.139(5) which restricts filing of revised return,not even non sending of ITR V
