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

Location is one of the main ingredients 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 will try to improve the address you enter to make it more accurate. For example, if you enter a street address, city, state, and ZIP code, the address enhancement system will add the ZIP+4, if possible.
