It is impossible to apply a cart price rule based on Subtotal (Incl. Tax) number.

Steps to reproduce:

  1. Configure product price to include tax.
  2. Create a tax rule and tax rate for 20%.
  3. Create a product with Price = 100 (this price includes tax).
  4. Create a new cart price rule with a coupon “10off” to apply $10 fixed discount if subtotal matches these conditions:

Conditions: If ALL of these conditions are TRUE : * Subtotal equals or greater than 100.*

Expected results:

There is ability to create a subtotal cart price rule with coupon to apply discount to subtotal including tax.

Actual results:

There are two options in cart rule conditions: Subtotal and Subtotal (Excl. Tax), and whatever one is selected, the rule is applied only to subtotal excluding tax.
