If ‘Automated Tax Setup’ option was used in WooCommerce setup, a plugin called ‘WC Shipping & Tax’ gets installed. This plugin adds tax when a new member fills out the Member Manager membership form no matter what settings are selected in Member Manager or WooCommerce.
NOTE: This is only an issue if you need to use the automated tax feature for other WC products that you are selling on your site but not for memberships.
We’re working on a fix for this issue. There is currently no workaround. But if you do not need to charge tax, you can remove the ‘WC Shipping & Tax’ plugin from your site.
NOTE: You should be able to make this change without any trouble. However, it is always a good idea to make a full backup of your site before making any changes.
