RMA -Returned item tax still showing in the order

Does anyone know why a Sales Tax amount would still be displaying in an order after the item has been refunded and the item cost is $0.00?

eg:

Subtotal : $0.00

Sales Tax : $0.50



this is what is being displayed in my admin after the order refund is completed.

This order is still showing a $ 0.50 balance.



does anyone know why the tax is not being removed along with the item cost, to make the balance of the returned order to be $0.00?
