I have set up a shop using Prestashop. I created a tax rule for my products and entered the VAT rates of all EU countries we sell to. When a user orders a product the VAT amount is calculated according to the address/country he entered in the checkout process, this works fine.

Unfortunately the VAT rate when the user is not connected is wrong. It should be 19% and not 17%, thus the products in the shop show wrong prices, e.g. 59,97 € instead of 60 €.

I haven't found out how the Prestashop frontend determines the VAT rate to be used to calculate the product price. There is no default VAT rate setting and the first rate in the table (lowest ID) has a VAT rate of 19%.

Does anybody know how that works ?

Thank you very much.
