I just tried using the effective tax rate of 9.975% for the QST with the description that reads "QST (9.5%)" and it works perfectly without having to change codereilly wrote:Why not just use the effective tax rate for the Quebec QST? Thus Under the Tax Class for Quebec, the Description would read QST (7.5%) but the Tax Rate would be 7.875% (rounds to 7.88%).

The only issue is handling taxes on shipping...anyone figured out how to do this yet
