# Configure Tax exempt setting on Cart

**Tax Exempt Setup on Cart** controls how the tax ID field behaves in your cart. There are 3 independent options — tick all of them, or only the ones you need.

## Required Tax ID Field on Cart

When enabled, customers must enter a valid tax ID in the cart before they can check out.

{% hint style="info" %}
If this setting is off, the tax ID field isn't validated at all — any input is accepted, and customers can proceed to checkout regardless.
{% endhint %}

## Auto Tax Exempt

When a customer's tax ID is valid, their order is automatically tax-exempted. This setting does two things: adds the VAT ID to the order's **Order note**, and exempts tax on orders with a valid ID.

{% hint style="warning" %}
If you enable **Required Tax ID Field on Cart** without also enabling **Auto Tax Exempt**, customers must still enter a valid VAT ID to proceed — but their order won't automatically be tax-exempted.
{% endhint %}

## Auto Redirect to Checkout

Even with an invalid tax ID, customers can still check out by clicking the checkout button a second time.

If the tax ID is valid, customers can check out immediately, with no second click needed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.samita.io/samita-wholesale-b2b/add-on-features/set-up-tax-exempt-for-customers-order/configure-tax-exempt-setting-on-cart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
