hi i m facing some issues in AP R12
1-what is the use of withholding tax group?
2-if you assign any tax code to a tax group and if you select that tax group in the supplier site then it calculates the tax by suming up all the tax codes and apply it to the invoice amount.....is this the functionalty of tax group or it is malfunctioning
3-i want only service related tax should appear when we enter the invoices of the supplier who provides the service...can i do this by using tax group if possible then how...
4-i want to track the record of sales tax in AP but sales tax is not appering properly means some tax do not have tax code other do not have tax rate etc,it is with vision instance ops corp resposibility where as in mine the tax is appering but nothing more than that where as i have given my legal entity in tax confriguration and sale tax is enabled

The purpose of Withholding tax is that in one go u cater the requirement of two differnt countries so when u assign the tax code to tax groups u have right to asign the rank and on the basis of this rank oracle calculates the tax.
let suppose 100 is the invoice amount 10% (rank-1)and 5%(rank-2) are the tax codes then oracle calculates 10(on first go for tax code of 10%) and then 4.5 (on 2nd go for tax code of 5%) as tax deductions resulting 14.5 as withhold amount and 18.5 as payable amount.
i have given the answer of first 2os hope so u got it right

thanks muskan i am intersted to know about withholding tax amount range....when i give any value in the amount range feild,at the time of entering the invoice oracle applies hold to the invoice "WHT amount range..etc"
