If you've followed the instructions in the 1 a. Getting Started article, you have already set your store's sales tax and labor tax. If you have items that have different tax rates than your sales tax, you can create a tax class for them in Settings > Tax Classes. For example, your state may charge a lower tax rate for clothing. To then apply a tax rate to your tax class, go to your store's sales tax settings in Settings > Sales Taxes.
For more information, see our Creating tax classes article.
AdvancedIf you have a multi-store account or need multiple sales taxes, you can create more sales taxes in Settings > Sales Taxes and assign them to your stores from Settings > Shop Setup.
For more information, please see our Setting sales taxes article.
