If nothing changed at all, you may be doing it wrong.
Which country are you billing from, which european countries are you selling to ?
Are you selling a single product/services, several with each different tax rates ?
How do you know which VAT rates you have to apply, are you vatmoss registered ?
It's a difficult subject, I'm really surprised it seems so easy for you (or anybody else)
