Don't show taxes for one country

here’s a solution that hides the taxes everywhere, which means woocommerce cart, orders, invoices and delivery notes:

/**
 * Hide Tax label from cart totals
 */
function example_get_cleaned_label($label) {
	return preg_replace( '/\([^)]+\)/', '' , $label );
}

/**
 * Hide Tax label from cart totals
 */
function example_hide_tax_label($value) {
	return example_get_cleaned_label($value);
}
add_filter( 'woocommerce_cart_totals_order_total_html', 'example_hide_tax_label' );

/**
 * Hide Tax label from order totals
 */
function example_hide_item_tax_label($total_rows, $order) {
	$total_rows['order_total']['value'] = example_get_cleaned_label($total_rows['order_total']['value']);
	return $total_rows;
}
add_filter( 'woocommerce_get_order_item_totals', 'example_hide_item_tax_label', 10, 2 );
