How does Avatax calculate when only the city state and zip are used?


I would like to know how Avatax will calculate if only city state and zip are passed as the ship to and from.

  • Avalara Avatax uses the Centroid (center point of the area) for calculation at the zip level, and will calculate the rate that exists in the middle of any given zip 5 or +4.
