add VAT if a cuntry is in EU

[nicubila]

Hi all


we need to find a way to add a VAT to the total cost if the country selected is within the EU. I could not find such a way.

We use also the "One page checkout" module from canin.sk, so the customer does not have to register. So the VAT should be added at checkout when the user selects the country

any suggestion will be appreciated
