I missed the deadline for filing retutn for FY 2007-08. Wanted to file before 31-Mar-2009. I have e-filed my return (through Taxsmile) on 30-Mar-3009 and have the ITR-V with me. Now, do I need to submit to IT department for acknowledgement today (31st) or since I have efiled before 31st, I have some more days to get acknowledgement?
