# About the Tax Exempt Groups Service Plugin

<blockquote class="important">

The Tax Exempt Groups service plugin lets your app provide tax exempt groups that a Wix site can use when calculating tax. A tax exempt group represents a category of buyers that are exempt from tax — for example, resellers or non-profit organizations — together with the regions where the exemption applies.

The exempt groups you provide with this service plugin are added to the site's available tax exempt groups when your app is installed, alongside groups created directly with the [Tax Exempt Groups API](https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-exempt-groups/introduction.md). Once available on the site, an exempt group can be applied to buyers so that qualifying buyers aren't charged tax in the regions you specify.

This service plugin is **configuration-only**: it has no methods for you to implement. You declare your tax exempt groups in the extension's configuration and Wix reads them — there's no runtime endpoint that Wix calls, so `deploymentUri` can be left blank.

The integration is done via an app created in your Wix Studio workspace with the Tax Exempt Groups Provider extension.

Learn more about [implementing a service plugin with Wix](https://dev.wix.com/docs/build-apps/develop-your-app/extensions/backend-extensions/service-plugins/about-service-plugin-extensions.md).

## What you provide

Each tax exempt group you declare includes:

- **`exemptTaxGroupName`** — the display name of the exempt group.
- **`id`** — a unique ID for the exempt group.
- **`exemptRegions`** — where the exemption applies: either `WORLDWIDE`, or a specific list of countries (each optionally narrowed to subdivisions).

## Use cases

- Provide a **Reseller** exempt group that applies to specific US states.
- Provide a worldwide **Non-profit** exempt group that applies to all regions.

## Get started

See [Configuration](https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-exempt-groups-integration-service-plugin/configuration.md) for how to add the extension and declare your exempt groups.

## Terminology

- **Tax exempt group:** A category of buyers exempt from tax in one or more regions. See the [Tax Exempt Groups API](https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-exempt-groups/introduction.md).
- **Exempt region:** A country — optionally narrowed to one or more subdivisions ([ISO 3166-2](https://en.wikipedia.org/wiki/ISO_3166-2) codes) — where an exempt group's exemption applies. Use the `WORLDWIDE` scope to apply the exemption everywhere, with no region list.
