Set who can mark sales tax-exempt
Open POS Settings and scroll to the Manager Approvals section. Find the Apply Tax Exemption on a Transaction row and toggle it on (the default) to require manager approval at the register, or off to let any cashier apply tax exemption without approval.
Apply tax exemption to a sale at the register
When a tax-exempt shopper’s items are in the basket, open the Orders menu in the footer and tap Apply Tax Exemption.


See the waived tax on the transaction
After the sale, open the Transactions page and find the sale by date, register, or amount. Open the transaction. In the Transaction Details card on the right, click Taxes to expand the breakdown. The expanded view shows each tax line item, ending with a Tax Exemption (“Your reason”) line that subtracts the waived amount from the total. The reason matches what the cashier entered at the register — “School” in the example above. If the cashier skipped the reason, the line reads simply Tax Exemption without parentheses.
