Currently, there is no way to refund an order stating the amount of tax. The tax reports are thus not exact when you have refunded an order because the VAT has not been decreased with the refunded order.

If Woocommerce allows us to add orders and to define which amounts of tva there should be on products + on delivery, when Woocommerce allow us to refund an order, it should allow us to fill the exact same information.

It would be very useful to allow shop owners to refund an order with the total price of the products + amount of VAT.

I think that the Refund button in the Edit Order's form should ask the Admin :
- the amount of the refund on products
- the amout of the refund on delivery
- the amout of tva to refund
