# Tax Classes V3

Create, update, and delete tax classes. Tax classes group products and shipping methods so you can apply different tax rates to each.

This API uses batch operations for `POST`, `PUT`, and `DELETE`. Successful responses use the envelope format `{ "data": ..., "meta": ... }`, with `POST` and `PUT` returning an array of tax class resources under `data`. `DELETE` is filter-based: pass the `id:in` query parameter to specify which tax classes to remove — there is no single-resource delete on this endpoint.
