For get customer is guest or not please use follow code:

$order = $this->_objectManager->create('\Magento\Sales\Model\Order')->load($id);
$id = $order->getCustomerId();
if(!$order->getCustomerIsGuest()){
	$customerId = $order->getCustomerId();
	$customer = $this->customerRepositoryInterface->getById($customerId);
	if ($customer && $customer->getId()) {
		$taxvat = $customer->getTaxvat();
	}
}
