## Get value from a Tax ID Element

Validates and retrieves form values from a Tax ID Element. If there are any input validation errors,
the errors are displayed by their associated fields.

`taxIdElement.getValue()` returns a promise. This promise returns an object with the following:

* `complete`, `true` if the value is well-formed and potentially complete.
  The `complete` value can be used to progressively disclose the next parts of your form or to enable form submission.
  It doesn't indicate whether a customer is done with their input. Rather, it only indicates that the Element contains a potentially complete, well-formed value.
  In many cases, the customer can still add further input.
* `empty`, `true` if both the business name and tax ID fields are empty.
* `visible`, `true` if the Tax ID Element is visible based on the `visibility` option and country.
* `value`, an object containing the current tax ID information. The `businessName` property may be `null` if not configured
  to be collected.

**Syntax:** `element.getValue(...)`

### Get value from a Tax ID Element

```js
var taxIdElement = elements.getElement('taxId');

taxIdElement.getValue()
.then(function(result) {
  if (result.complete) {
    // Allow user to proceed to the next step
    // Optionally, use value to store the tax ID details
  }
})
```

```es_next
const taxIdElement = elements.getElement('taxId');
const {complete, value} = await taxIdElement.getValue();
if (complete) {
  // Allow user to proceed to the next step
  // Optionally store the tax ID details with value
}
```
