Disable tax programmatically for a specific user role

问题

In my woocommerce web site, I have enable Tax in general WooCommerce settings.

I would like to disable tax for a specific user role programmatically ( with any hooks ), from my shop, checkout page and from order email.

How could I achieve this?

Thanks

You can't disable WooCommerce tax for a specific user role programmatically, but you can apply for a specific user role a zero tax rate.

First you need to have this specific user role set in worpress. If it's the case, let say that this custom user role is 'resellers' for my code example.

Second, you have to enable in WooCommerce settings a zero tax rate:

And then for each country, you will have to set this zero tax rate:

Third - Then this function hooked in woocommerce_product_tax_class will do the trick:

function zero_rate_for_custom_user_role( $tax_class, $product ) {
    // Getting the current user 
    $current_user = wp_get_current_user();
    $current_user_data = get_userdata($current_user->ID);

    //  <== <== <== <== <== <== <== Here you put your user role slug 
    if ( in_array( 'resellers', $current_user_data->roles ) )
        $tax_class = 'Zero Rate';

    return $tax_class;
}
add_filter( 'woocommerce_product_tax_class', 'zero_rate_for_custom_user_role', 1, 2 );

You will just need to put instead of 'resellers' your desired user role slug.

This code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and fully functional.
