# Taxation Items

The TaxationItem object is used to add a tax amount to an invoice item. In the typical use case, the tax amount that you specify in the object is calculated by <a href="https://docs.zuora.com?resourceId=billing-zuora-tax-overview" target="_blank">Z-Tax</a> or a third-party tax engine such as <a href="https://docs.zuora.com?resourceId=billing-direct-avalara-integration-overview" target="_blank">Avalara</a> or <a href="https://docs.zuora.com?resourceId=billing-connect-tax-engines" target="_blank">Connect tax engine</a>.

Changes that you make with this object affect the product charges in your product catalog, but not the charges in existing subscriptions.
