I currently have a system that sells to both consumers and businesses. If a member login is tagged as a dealer, then they see trade pricing and can purchase as such. The problem with this is that they are still charged the same taxes as consumers. This is not legal in the USA, as sales tax does not apply to wholesalers who will then sell to consumers (that pay taxes).
Is there a way to set a different (tax exempt) tax rate for members with specific tags or that have trade pricing activated? The only thing I can think of at the moment is having a promotion code applied in the background that subtracts the tax percentage, but since the promotion system still doesn't allow multiple promo codes, they would be unable to take advantage of any additional discounts simultaneously.
