You need to modify a template. Do not modify the core WooCommerce template, but rather make a copy of it to your theme, using the WooCommerce template override system. For help with that, refer to the WooCommerce docs on using the template override system.

In the price.php template, you will add this bit of code where you want the price, including tax (VAT):

<?php echo woocommerce_price($product->get_price_including_tax()); ?>
Note: the price.php template that you modify should be located here in wp-content/themes/[your theme folder]/woocommerce/single-product/price.php
}

i would like to disable/or set zero tax rate to the specific user role for example wholesaler, do you know about any wat how to realise it?
