What does "Invalid ExemptReasonId and region combination" mean?

The following error appears on the History tab of a certificate:

API call initiated for certificate: Failure. 

(Invalid ExemptReasonId and region combination) 


Basic Certificate:

  • The exemption reason is not valid for the exposure zone (state/province/country as specified in the error)
  • Go to Details on the certificate > click Edit:
  • Choose a different exempt reason in the drop down
    • Choose one that is appropriate based on the certificate provided
    • Custom is a generic exemption, it is handled as an L Other type exemption
  • Click Update Certificate

Multi-jurisdictional Certificate:

 This happens when the reason code you've selected is not exempt in the region or regions listed in your multi-jurisdictional certificate

  • This often happens when states that do not have a sales tax are part of your certificate (New Hampshire, Oregon, Montana, Alaska, Delaware)
    • Since the above states do not have a sales tax, these regions will always fail as part of a multi-jurisdictional certificate

To resolve this, go back through the validation process, but this time exclude the region(s) causing the API error.
