Geolocation

From Tax Rates Wiki

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

1. Mapping jurisdiction boundaries precisely using latitude and longitude
2. Constantly updating a proprietary database with the latest rate and taxability rules
3. 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 AvaRates, a sales tax calculator with map-based geolocation. It's a free demonstration of the power and accuracy of Avatax.
