Geolocation

From Tax Rates Wiki

Avalara uses geolocation to provide precision rate decisions.

Geolocation is Avalara's process of creating unprecedented rooftop-level accuracy for sales tax rates with the following techniques:

• Mapping jurisdiction boundaries precisely using latitude and longitude
• Constantly updating a proprietary database with the latest rate and taxability rules
• Combining our jurisdiction and rate information with mapping technology

This allows Avalara to precisely determine nexus for a given address or location. You can see this in action with Avalara Sales Tax [1], a sales tax calculator with map-based geolocation. It's a free demonstration of the power and accuracy of Avatax.
