Sales Tax all over the place and not correct.

I'm not sure where it went wrong exactly but all of the sudden the checkout is charging everyone sales tax and the amounts aren't correct. We have a Virginia sales tax set up but it's charging sales tax for international orders as well and the percentage isn't accurate at all.

Anyone have any suggestions on how to rectify this issue? I do have the latest version of Wordpress and Marketpress.

Additionally I've opened up support access too.
