Microsoft Customer Service and Support adds sales tax when applicable to the cost of technical support for North American customers. Tax is charged at the rate appropriate to the location where the support is received. Customers who are "tax exempt" must provide a tax exemption certificate to Microsoft at the time of purchase to avoid being charged sales tax.
Important The information in this article applies only to sales tax that is charged for the credit card purchase of technical support for North American customers. The process for submitting tax exemption certificates to Microsoft for other issues differs, such as when purchasing software licenses or support through a purchase order.

Billing address and service delivery addressThe service delivery address is the physical location of the computer systems that are being supported. This address may differ from the billing address of the credit card that is being used to purchase technical support.
The service delivery address is used by North American Customer Service and Support to determine whether sales tax should be applied to the cost of technical support and at what rate.
