During the last WooCommerce update I read that the tax page had been streamlined a bit. I hadn't realize the functionality was being changed as well! I have a 'special' tax for local customers--it's a negative value (-7%), so that I can give a discount to our local customers without using a coupon, before local tax is applied. I noticed on our last order, the customer did not receive this discount--after looking into the new tax page (which I should have done sooner) I can now see that no value less than 0 is allowed as the tax rate. Does anybody have any clues where I might look for a solution to allow negative tax rate? I'm using Woo 2.0.4, but I'm assuming 2.0.5's tax page is set up in a similar fashion.
