About the Tax Regions API

Note: This API will be deprecated on September 30, 2025. Use the identical Tax Regions API in the @wix/ecom module instead.

The Tax Regions API allows you to create and manage tax regions to apply different tax treatment based on location. Use the Tax Regions API together with the Tax Groups API and the Tax Calculation API to customize the application of tax for a business.

Before you begin

It's important to note the following before starting to code:

  • A tax region requires an appId for an available tax calculator. Call List Tax Calculators to retrieve a list of available tax calculators for a site.

Terminology

  • Tax calculator: An app that is used under the hood to calculate tax for a Wix site. The app calculates tax based on the tax group of the product and the tax region of the sale. A site assigns each tax region to the Wix manual tax calculator or an external calculator app to properly calculate tax.
  • Wix manual tax calculator: The default tax calculator installed with a Wix site. The tax rates to apply for this calculator can be manually adjusted in the Tax Settings in the Wix dashboard.
