It does not matter if you are salaried or self employed. The due date was 31/07/2014. You have to file the return for Ay 2014-15(FY 2013-14) latest by 31/03/2015 and pay the taxes with interest before that. After that penalty might be levied.
If you are asking about the Advance tax for AY 2015-16, the last installment should be paid before 15/03/15.
