Can I calculate tax in a Streamlined Sales Tax (SST) state using only Lat and Long coordinates?


You are a Streamlined Sales Tax (SST) filer and would like to use only Latitude and Longitude coordinates for the addresses on your transactions.

  • At this time, SST filers are not able to use only Lat/Long coordinates on transactions to registered SST states.

    • For states that you are an SST filer in, a full address must be used:

      • Address Line 1

      • Address Line 2

      • Address Line 3

      • City

      • State

      • Zipcode

      • Country code

    • However, if you are an SST filer in Washington, but a regular filer in Florida, you can use Lat/Long coordinates only for the Florida transactions.
