  • We calculate VAT (and other international tax) using the:
    • Addresses provided on the sale to determine location
      • We apply tax in those locations based on where you have told us to collect tax in your company Nexus
    • Tax codes assigned to your items (or sent with the item) to determine taxability of the items
    • Customer specific settings based on the exemptions applied to the transaction or set up for the customer record
  • For VAT we also consider Buyer's VAT Number and Place of Supply (Importer of Record and Permanent Establishment)

NOTE:  Calculating VAT (or any international taxes beyond US and Canada) requires Global tax calculation service, ask your account manager
