Important:
Wix Mobile POS allows you to make sales from your phone while on the go. To process payments in a physical store, learn more about Wix POS Register.
When selling online, the tax rate is usually determined by your customer's location. However, for a POS transaction, it's determined by the business location you entered in the Business Info page in your site's dashboard.
To set up tax collection for a mobile POS:
Click Settings.
Click Business Info and enter your business address in the Business Info page.
Note: Make sure your address includes a zip code / postal code.
Click Tax and set up a tax rule for your region.
Note: If no tax rule is set up, POS transactions are taxed at 0%.
