What is your store name?
To activate this option in your cash register – first go to the management system:
Under “Preferences” select “In-store”, then “Receipt and Order Preferences”, and select to enable the option for “Allow to disable tax in register”. Once you’ve enabled this feature, go back to your Cash Register. You will now see a little toggle button next to “tax” which can be turned off per your discretion. This will turn the tax off for the entire purchase.
