# 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://knowledgecenter.zuora.com/Billing/Taxes/A_Zuora_Tax" target="_blank">Z-Tax</a> or a third-party tax engine such as <a href="https://knowledgecenter.zuora.com/Billing/Taxes/Direct_Avalara_Integration" target="_blank">Avalara</a> or <a href="https://knowledgecenter.zuora.com/Billing/Taxes/Additional_resources_on_taxes/AA_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.
