Can income tax return be filed more than one year? For example, a person Y, who failed to file his income tax return for PY 04-05, 05-06 and 06-07, feels like he was cheating government all along and now want to disclose his income for all these years and hence wants to file his income tax return in AY 2008-09 along with income of PY 07-08..

Can he do so? If he does, wat are the consequences he has to face for not filing previous years' returns?
