Why am I receiving 'Entity use code is not a valid reason' for the customer in Montana error message in AvaTax?


Trying to make a customer exempt in Montana and it throws an error that it is not a valid reason.

  • Montana does not have sales tax so any exemption reason code will throw that error there.
  • Simply run the transaction as normal and it will not calculate sales tax there.
