As a DIY platform, the approach Squarespace takes with taxes is to let merchants enter in the rates they need to collect, then provide a calculator that can apply those rates to a shopping cart. Squarespace’s role is thus not to know the exact details of a given tax system, but rather, to provide a tool that can effectively model the most common ones.
