Along with invoice creation, ARMember is also powerful at taxation management while generating invoice for the membership plans. All thanks to ARMember’s Invoice and Tax addon that you can find under ARMember > Add-ons in your WordPress dashboard.
Once you activate this free built-in addon, simply navigate to ARMember > General Settings > General Options where you will find Sales Tax Settings. Here, you can enable the tax module on the plan purchase option.
After enabling this option, you will have access to two different methods for defining the tax percentage:
i) Common Tax (which will be common for all countries)
ii) Countrywise Tax
Choose the one that best fits your requirements. Make sure that the percentage of tax you set at this level will be applied on the final payable amount on plan + sign up page.
