I believe I have the plugin set up properly. I notice in the field for Charge the User there is a checkbox to automatically add and collect sales tax. I have checked that.
I have also set up to accept and manage Sales Taxes in my Stripe account.
But there is a field for the Tax rate ID’s Source. I cannot figure out a) exactly what this is, and b) where to get it. But I suspect it is required, of course.
Any help would be appreciated!
