We’ve recently made several major improvements to how taxation is handled in Spree. These changes were made at the behest of our community, especially our European friends struggling to have a simple implementation of VAT. After considerable discussion and coding, the changes are now ready for release.
Please see our recently revised Taxation Guide for the complete details. There is also a work-in-progress version of the 1.0 release notes which highlight some of the changes made. This code is available right now on the “edge” and will be part of the official 1.0 release later this month.
