Exempt a customer with a tax exemption number in Microsoft Dynamics 365 Business Central

When you associate a customer with an exemption number, AvaTax exempts the customer from sales tax but does not track the customer's exemption information. To track customer exemptions, use Exemptions or CertCapture.


  1. In Microsoft Dynamics 365 Business Central, open the record for the customer you want to exempt from tax.
  2. Enter the customer's exemption number in the Tax Exemption No. field to exempt all transactions for that customer from sales tax.

Exempt transactions post in AvaTax for reporting purposes, but AvaTax does not track customer exemption information.
