After you integrate with AvaTax in the Sales Set Up AvaTax Integration window, a new field appears on the Sales Info tab in the IN Stock window. The Tax Code from AvaTax field allows you to assign a specific AvaTax Tax Code to each stock item.

If you have several stock items that use the same AvaTax Tax Code and have the same IN Code attached, you can enter the AvaTax Tax Code in the Tax Code from AvaTax field in the IN Inventory Codes window.

The AvaTax Tax Code you enter on the Sales Info tab in the IN Stock window will override the AvaTax Tax Code attached to the IN Code.
