I have a product cost with zero tax when purchase. for resell, i tax 10.75%. this overrides the per line item tax column; however, the tax calculation at the bottom is not displayed and the tab label still says "Tax 15% $ 0.00". When I switch back to the default 15% tax for the item, tax is then calculated and displayed in the tax line: "Tax 15% $ 224.25".
I can't seem to figure where to change the tax settings.
