# Configure Tax exempt setting on Cart

**Tax Exempt Setup on Cart** helps you configure how the tax ID is validated in the cart. 

There are 3 options for this setting, you can **tick all** or **tick on specific feature(s)** you want to apply only. 

* **Required Tax ID Field on Cart:** When enabled, customers must enter **a valid Tax ID** in the cart before proceeding to checkout.

***If you don't tick on this setting in the app**, the Tax ID field will not be validated, and **any input will be accepted**, allowing customers to continue to checkout without verification.*&#x20;

* **Auto Tax Exempt:** As long as the tax ID is valid, order will auto-get tax exempted.&#x20;

This function does two things: **Auto-add VAT ID to the Order note** section of in the Order and **Auto-exempt tax for orders** that have **valid tax IDs**

If you enable the **Require Tax ID Field on Cart** setting without also enabling the **Auto Tax Exempt** setting, the app will only require customers to enter a valid VAT ID before checkout, but it will **not** automatically exempt the order from tax.&#x20;

* **Auto Redirect to Checkout:** Even if the tax ID is invalid, customers can still be able to checkout by **clicking on the checkout button twice**.&#x20;

On the other hand, if the Tax ID is valid, customer will be able to checkout immediately.&#x20;
