 * PHP Notice: Undefined variable: tax_class_id in /var/www/client/wp-content/plugins/
   checkout-fees-for-woocommerce/includes/class-alg-wc-checkout-fees.php on line
   859
 * The get_used_coupons function is deprecated since version 3.7. Replace with WC_Abstract_Order::

 * Hi [@7grafix](https://wordpress.org/support/users/7grafix/),
 * I have tried to replicate the issue on our staging site, but I am unable to replicate
   it. So, can you please provide us the screenshot of the WooCommerce Tax Settings
   and also the screenshot of the issue which you are facing.
 * This would be helpful to assist you in a better way.
 * Regards,
    Kenil Shah
