Dear Experts,

One of my friends father firm who has filed income tax returns since 1976 and continued to file till 31/03/2002. 

From 01/04/2002 he has business loss upto 31/03/2012. So he skipped filing returns. from 01/04/2012 his firm does makes some profit. so please tell me what is the procedure for filing of IT returns from 01/04/2012.
