hi,
just wanted to know what is the last date of depositing self assessment tax? I need to file income tax return for assessment year 2008-09 and tax liablity is more than the TDS my employers have deducted. If I submit the self assessment tax before 31 jul 08 does that attract any interest also?

Please suggest...
