Som da, Thank you very much for your generous effort. Its such an useful utility. Only the Educational Cess is not working out correctly . Please check.
Example :- Tax on total income =84970.00 ,
Add Education & cess @ 2% & 1% = 2549.00
But your I.T. Calculator 2015-16 shown as Rs. 2532.00 , Please check and clarify.
