We sell and ship alcohol, and for shipments to NH we need to recapture the lost alcohol tax on sales shipped into the state. So we need to charge customers 8% of the product value and remit that to the state. The problem is NH has no existing sales tax, so I can't do a sales tax override for NH (like I do for other states where we need to collect something similar).
I can't for the life of me figure out how to add a surchage that is 8% of the product sale on shipments going to NH. Anyone have any ideas?
