# Tax Classes

Tax classes group products and shipping methods so different tax rates can be applied to each. The Tax Classes API surface is split across two API versions:

* **V3** — write operations: create, update, and delete tax classes ([V3 reference](/developer/api-reference/rest/admin/management/tax/tax-classes/v3)).
* **V2** — read operations: list all tax classes or retrieve a single tax class by ID ([V2 reference](/developer/api-reference/rest/admin/management/tax/tax-classes/v2)).

There is no V3 read endpoint at this time. To list or retrieve tax classes, use the V2 endpoints. New integrations should otherwise use the V3 write endpoints, which support batch operations.
