Please refer to Configuring Taxation Settings.
Important: Before starting reseller business, ensure your preferred configuration of taxation settings, including tax zone assignment rules. When your reseller subscription becomes effective, your tax zone assignment rules may be automatically propagated from your provider. This means that, for example, if your provider uses Vertex O Series or EZTax or another third-party tax service, you will not be able to do business without either signing a contract with that tax service or manually changing your taxation configuration.
