Base tax management functionality (tax zones, classes, rates and rules) will be available out-of-the-box at some point.
We also know that a lot of B2B businesses are dealing with a variety of additional scenarios, e.g. managing tax exempt certificates provided by their customers, or complying with specific regulations when moving different types of goods between warehouses in different countries and tax jurisdictions.

There is a number of service providers who do just that, and we are considering to provide a few pre-built integrations with some of the leaders in this area as well.
