Add Tax Exempt form on checkout in woocommerce

Question

I am trying to add a form to my checkout page so when a user clicks the \'Tax Exempt\' checkbox, a textbox will popup and ask the user what the Tax Exempt Id number is.

Answer 1

Because $cart->remove_taxes(); is deprecated. This is what I used instead.

I didn't have a form on the frontend, but have a user roll that is tax exempt. This was my solution.

Also worth noting that set_is_vat_exempt(true) also works in the US to set as tax exempt.

/**
 * Set customer as tax exempt if user is a wholesale customer
 */
function remove_tax_for_exempt( $cart ) {
    global $woocommerce;

    if ( is_user_logged_in() && current_user_can( 'wholesale_customer' ) ) {
        $woocommerce->customer->set_is_vat_exempt(true);
    }
    return $cart;
} 
add_action( 'woocommerce_calculate_totals', 'remove_tax_for_exempt' );
