Understanding Service Taxes Paid Externally

A supplier who provides a service to you during a month might also provide services to other companies during that month. The other companies might have withheld INSS taxes for the supplier. Occasionally, a supplier might make an INSS contribution for a month through a bank or government agency. You must consider the amounts that other companies withheld and the amounts that a supplier might have contributed for INSS when you calculate the amount of INSS tax that you withhold for the supplier.

You use the Service Taxes Paid Externally program (P76B0403) to enter the information that your supplier gives to you about the INSS tax amounts that others hold for the supplier. You must enter the information about the INSS tax amounts that are held by others before you calculate the INSS taxes which you must withhold for the supplier, and before you calculate IR taxes for the supplier.

You need only enter the amounts that are held by others when your supplier is an individual or cooperative, and when the supplier was paid for services to another company in the same month in which you pay the supplier for services or the supplier made an INSS contribution in the same month in which you pay the supplier.
