Magento 2 - Cart Price Rule to Discount Subtotal While Keeping Tax

Question

I am trying to create a Cart Price Rule which allows for a 100% discount of the order's subtotal, while still including the subtotal's taxes to the customer. Ex:

Customer is ordering $100 of goods (subtotal). $12 in tax is included on this order. We would like to only charge them the tax.

Is there a means to do this?

Answer 1

You can set Apply Customer Tax value to After Discount
