Chargify offers three types of tax settings:
Custom Taxes: Tax rates defined and maintained by you to collect taxes in any geographic country/region. This includes general use and generic taxes, as well as support for European Union VAT tax.
Avalara Managed Tax: Automatic sales tax collection for US and Canadian merchants, as well as European Union VAT Taxes. You pick the areas that you are responsible for collecting taxes in, and Chargify uses the Avalara tax service to find and apply the correct rates.
Tax Exempt Customers: Ability to mark a customer/subscription as tax exempt.
