Setting up taxes in Drupal Commerce is a snap. The component comes bundled with some predefined tax rate plugins, such as European Union VAT and Canadian sales tax.
This means that enabling these tax types is as easy as checking a box. More complicated tax regions, like you would find in the United States, have integrations available with services such as Avalara AvaTax, TaxCloud and more.
Custom tax types can also be created very easily.
