I assume that you set the customer attribute on registration, not the customer_address attribute.

You have to create a default address for the new customer and add the VAT-ID to this address. Then it will show in the checkout page.

Have a look at the eav_attribute table:

SELECT * FROM eav_attribute WHERE attribute_code LIKE "%vat%";

You will see:

  • attribute taxvat for entity type customer (I assume you're currently using this)
  • attribute vat_id for entity type customer_address

Use the 2nd.

  • It really puzzles me why there are two fields for the VAT ID. It is really confusing for the customers.

    Yes, same. I think the customer-attribute ("taxvat") is nonsense. It makes more sense to have the VAT ID at the customer's address, because different addresses may require different tax calculations. Commented Oct 26, 2020 at 14:40
  • I agree completely. I guess it is because of the automatic customer group selection at the registration phase, but I'm sure this could have done in a more sensible way. Maybe set the customer taxvat as the default VAT ID of the address if no other is given or something like that. Was it like this in M1 as I have a migration case where migrated registered customers are all of a sudden ordering with tax included as they expect things to work as they worked in M1?

    Yes, M1 also had 2 attributes IIRC. But I think the separation of customer and customer_address wasn't so strict back then, or you might have had a customization in M1 that handled this. Haven't worked with M1 a lot lately, so this is from memory obviously. Commented Oct 26, 2020 at 15:03

If you have following setting enabled the VAT Input field should be display in checkout:

Stores -> Configuration _> Customers -> Customer Configuration -> Create New Account Options- > Show VAT Number on Storefront


this code should help you:


namespace Test\VatId\Model;

use Magento\Customer\Model\ResourceModel\Address\CollectionFactory;

class GetVatIdList
 * @var CollectionFactory
private $collectionFactory;

 * GetVatIdList constructor.
 * @param CollectionFactory $collectionFactory
public function __construct (
    CollectionFactory $collectionFactory
) {
    $this->collectionFactory = $collectionFactory;

public function execute($customerId)
    $addressCollection = $this->collectionFactory->create();
    $addressCollection->addAttributeToFilter('parent_id', $customerId);
    $addressCollection->setOrder('updated_at', \Magento\Framework\Data\Collection::SORT_ORDER_DESC);
    return $addressCollection;

This code takes the tax vat saved in the customer addresses and provides the value of the most recent one.
