Avalara calculates taxes for your products based on an extensive list of tax codes. Unless you are relying on UPC codes, you must manually enter a tax code for each of your products. For all version's of Prestashop this can be accomplished by visiting the edit product page of your back office. However, the tax code field location differs between versions of Prestashop.
Prestashop Version 1.6.1.x
The tax code field is located under the "Prices" tab of your product's edit page.
Prestashop Version 1.5.6.x
The tax code field is located under the "Information" tab of your product's edit page.
To manually specify that one of your products is not taxable you can enter NT as the value of the tax code field for a product.
Please note, that if you do not set a tax code for a product, Avalara will attempt to calculate taxes based off of the UPC code that you have set for each product. If neither a tax code nor a UPC code are set for a product, Avalara will assume a default tax code of P0000000.
You can exempt tax calculation for all of a customer's orders by choosing an Entity Use Code for that customer. This setting can be found on a customer's edit page in the Prestashop back office.
