Fields on customer records in Microsoft Dynamics 365 Business Central that interact with AvaTax

Set the tax area code for a customer in Microsoft Dynamics 365 Business Central to ensure that AvaTax is calculating sales tax for that customer. To assign many customers at once, set the tax area code for customers to AvaTax in a batch.

Set the tax area code to AvaTax in Microsoft Dynamics 365 Business Central

In Microsoft Dynamics 365 Business Central, there are several fields on a customer record that AvaTax looks at when calculating sales tax:

  • Tax ID No: In AvaTax this is the Business Identification Number (BIN). This enables VAT reverse charge features related to cross-border transactions.
  • Tax Liable: Set to "yes." If set to "no," AvaTax assumes the customer is exempt and doesn't calculate tax.
  • Tax Area Code: Set to AVATAX. This tells Microsoft Dynamics 365 Business Central to use AvaTax to calculate tax.
  • Tax Exemption No: If there is anything in this field, AvaTax considers the customer tax exempt.
