With smart tax, tax inclusive items are recalculated with a standard tax rate when both food and alcohol are on a check. Essentially, tax inclusive items are flipped, generating additional revenue. For example, the $3.00 Budweiser ($2.80 for the net amount) now becomes $3.00 plus 7%, making the Budweiser $3.21.
