Taxes are configured at the POS level and are not a function configured in Punchh nor do any redeemables, or discounts from Punchh have a tax configuration. If you are seeing where an item discounted from a Punchh discount/comp is still charging Tax, please check the specific menu item's Tax configuration/class in your POS.
If there are items that this is not occurring with, a suggestion would be to compare the set-ups of the two items.
