Why is the exemption no field not making the customer exempt in Avatax?


I'm sending over the exemption no field in my transaction and tax is still appearing on the total.

  • This can happen if your ECMS is set to Required for the country you're transaction ships to.
  • Switch the setting in ECMS to Optional and save, this will then allow either Exemption No field or Entity use code/Customer usage/type to single handedly make a transaction see that customer as exempt.
