First, click the Edit button under the item.
2. Then go to the Tax tab.
Tax Exemption
To exempt an item from tax, just turn on its Exempt from Tax setting, then click the Save button.
Multiple Tax - Item-Specific
If you have a single tax setting, the tax rate will already appear in this section, and you don't have to do anything else.
But if you have item-specific taxes, you can also turn them on in this section. For example, if you have an alcoholic liquor item that will be charged a Sin Tax, then just turn it on in this section. Then click Save.
