Learn how Global Tax Determination enhances addresses to provide the most accurate tax rates.

Location is one of the key parts of a tax calculation, so it is important to provide the most accurate address possible to get the correct tax rate. Global Tax Determination's address enhancement feature tries to improve the accuracy of the addresses you enter. For example, if you enter a street address, city, state, and ZIP code, the address enhancement system will add the ZIP+4, if possible.
