Can CPF share given by govt. added in the Financial gross
salary while calculating Total gross salary at the end of
Financial year.For eg: My gross salary is Rs.X during a
Fin. year & govt share of CPF is Y then Total Fin. Year
gross salary is =X+Y,is it correct?

A Service provided has provided bill amounting rs. 100000
dt. 30/04/2013 & i have paid amount with 30000 Rs. as on
24/5/2013, & 20000 paid on 7/6/2013 & rest of the amount has
been paid as on 15/6/2013 then on which amount TDS has been
deducted. may it deducted on Bill amount or payment amount?
If bill amount then at which date TDS entry should be done ?
& if on Payment date then which date. and if i want to
compute interest for late payment of TDS then Which date
should be consider for interest payment computation.
Do the needful for the same.
