Currently MemberMouse doesn't have native support for taxes or VAT.
We recognize the importance of providing tax support and our development team has started work on including this in MemberMouse. Providing tax support is complex and very involved so we're taking our time to ensure that the tax module we release supports a multitude of international tax scenarios.
If tax support is something that's essential to your business today, MemberMouse may not be the right solution for you.
If you are a current MemberMouse subscriber and are interested in learning more about a workaround that some of our customers have employed, you can find the answer in the General FAQ article Does MemberMouse Support Tax or VAT?
