WooCommerce set tax exemption based on user role

functions.php

<?php
add_filter( 'init', 'wc_tax_exempt_user_roles' );
function wc_tax_exempt_user_roles() {
	if ( ! is_admin() ) {
		global $woocommerce;
		if ( current_user_can('wholesaler') || current_user_can('distributor') ) {
			$woocommerce->customer->set_is_vat_exempt(true);
		} else {
			$woocommerce->customer->set_is_vat_exempt(false);
		}
	}
}
?>

Hello, this would be really useful, but it doesnt work for me. Im using woo 2.1.16. Should all catalog prices be displayed without tax?

Sorry, it works. Just Dynamic Pricing still shows prices with tax - do you have any idea how to fix it?

Hi
I'm in Canada and we have two taxes (PST & GST) that could be exempt. Just looking at this code snippet, for customers that would either be exempt from all taxes (so zero rate including shipping) or customers that would be exempt from the PST tax only. Would I duplicate the code snippet above for both tax classes I created? Do I also need to create two customer tax exempt and PST exempt user roles?
Thank you

This snippet won't work in your use case. You should take a look into the tax classes instead and define rules based on them.
