Hi there,

unfortunately we cannot provide an out-of-the-box tax handling, that works in every country, every state, every county, every city for all customer groups and all merchandise possible in the world.

It is hard enough to keep up with our german tax regulations.

But we want to provide an easy interface to easily adapt to any possible situation. This is why we have changed our tax handling. You can read more about this here: http://www.silvercart.org/blog/new-vat-handling-implemented/
