Yay taxes!   My shop is located in PA.  We tax goods and shipping to people only in PA.   When a new customer, who it not registered with my site, adds things to their shopping cart and views their cart, it shows Tax.   If I turn the tax option off, it obviously does not show tax.  But when I place something in my cart and pretend to check out, showing I am in PA, it does not add tax.    Is there a way to show tax, only after they have registered and say that they are in PA?
