## Create a Tax ID Element

`checkout.createTaxIdElement(options?: object)`

This method creates an instance of a Tax ID Element.

> This feature requires the `custom_checkout_tax_id_1` beta. To use it, pass `betas: ['custom_checkout_tax_id_1']` when initializing Stripe.js.

- `options`
  Tax ID Element initialization options.
    - `visibility`
      By default, the Tax ID Element displays when the user is in a country that supports tax ID collection.
Specify `always` to display the element regardless of the user's country.
Specify `never` to hide the element completely.

When `name_collection.business.enabled` is `true` on the Checkout Session and `visibility` is `auto`, the element displays regardless of the user's country. In countries that do not support tax ID collection, only the business name field shows.
    - `fields`
      By default, the Tax ID Element collects all tax ID information.

If it's not necessary for you to collect all fields, you can disable Tax ID Element collection of certain fields with the `fields` option.
      - `businessName`
        Specify `always` to collect the business name.
Specify `never` to not collect the business name.
Default is `auto`.

When `name_collection.business.enabled` is `true` on the Checkout Session, setting this to `never` signals that you are collecting the business name through your own input via `updateBusinessName()` instead.
    - `validation`
      By default, the Tax ID Element will enforce preset validation for each field. You can customize the settings by using this option.
      - `businessName`
        - `required`
          Specify `always` to make business name a required field.
Specify `never` to make business name an optional field.
Default is `auto`.

When `name_collection.business.enabled` is `true` on the Checkout Session and `name_collection.business.optional` is `false`, the SDK overrides this to `always` regardless of what you set here.
      - `taxId`
        - `required`
          Specify `always` to make tax ID a required field.
Specify `never` to make tax ID an optional field.
Default is `auto`.
    - `verification`
      Configure real-time tax ID verification. Requires the `custom_checkout_tax_id_verification_1` beta. To use it, pass `betas: ['custom_checkout_tax_id_1', 'custom_checkout_tax_id_verification_1']` when initializing Stripe.js
      - `taxId`
        - `mode`
          Specify `if_supported` to enable real-time tax ID verification for supported tax ID types.
Specify `never` to disable verification.
Default is `never`.
