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.
- In Microsoft Dynamics 365 Business Central, open a record for the customer for which you want AvaTax to calculate tax.
- Enable the Tax Liable toggle. This option must be enabled for the transaction to get the tax calculation done by AvaTax.
- In the Tax Area Code field, enter AVATAX.
This tells Microsoft Dynamics 365 Business Central to use AvaTax to calculate tax for this customer.
