Tax is added for product with no tax

[aravot]

Tax is added for product with no tax; VAT Id = 0 none
(If not mistaken I remember this was fixed, tried to look at old tracker but no more)

Product display is different for different configuration but in all configuration tax is add but it shouldn't. Will try to explain with images.

Tax mode = Based on shipping address.


Product has no tax assign to it; VAT Id = 0 (-none-) hence no tax should be added.


Product in front-end is shown correctly without tax.


However product in checkout has tax applied to it; Wrong



Tax mode = Based on vendor address.


Product has no tax assign to it; VAT Id = 0 (-none-) hence no tax should be added.


Product in front-end is shown incorrectly (it shows with tax it shouldn't because product has no tax assign to it).


Product in checkout has tax applied to it; Wrong


Price display changes when in 'Shopper Group'-> 'Show Prices including tax' is checked/unchecked but the final result (checkout) product has tax.

To solve this problem, go to SHOPPER->LIST SHOPPER GROUPS.

Edit the DEFAULT shopper. Uncheck the "Show Prices Including Tax" checkbox.

That fixed it for me.

Your reply has nothing to do with the bug, the bug is about when VAT Id is equal to ZERO

Hello, I am having this exact same problem.

No VAT (sales) tax is assigned to a Virtuemart product but Virtuemart is still charging tax.

Joomla 1.5.25 and Virtuemart 1.1.8.

Does anyone have a fix for this problem?

We are willing to pay a consultant for any advice or a fix.

I was facing the same issue with my Joomla 1.5.22 and VirtueMart 1.1.8 stable version.

After debugging I found the solution of same.

Actual Problem with code:
--------------------------------
- While getting tax rate  from VM system using call of get_taxrate( $ship_to_info_id = '' ) method in joomlavm/administrator/components/com_virtuemart/classes/ps_product.php file.
- In that function have some conditions which stores the taxrate in session, and that is based on vendor_id.
- Every products with same vendor_id will be applied with same taxrate. Though in Admin panel we have not set VAT/TAX Rate field value. (i.e. 0 - none ).

/**
    * Get the tax rate...
    * @author soeren
    * @return int The tax rate found
    */
   function get_taxrate( $ship_to_info_id = '' ) {
      global $page;
      $ps_vendor_id = $_SESSION["ps_vendor_id"];
      $auth = $_SESSION['auth'];

      if( !defined('_VM_IS_BACKEND' ) || $page == 'product.product_list' || $page == 'order.order_print') {

         $db = new ps_DB;

         if ($auth["show_price_including_tax"] == 1) {

            require_once( CLASSPATH . 'ps_checkout.php' );
            if (! ps_checkout::tax_based_on_vendor_address ($ship_to_info_id) ) {
               if( $auth["user_id"] > 0 ) {

                  $ship_to_info_id = !empty($ship_to_info_id)? $ship_to_info_id : vmGet( $_REQUEST, 'ship_to_info_id');

                  }

                     $_SESSION['taxrate'][$ps_vendor_id] = $db->f("tax_rate");

                  else {

               }

            }

         }
         else {
            $_SESSION['taxrate'][$ps_vendor_id] = 0;
         }

         return $_SESSION['taxrate'][$ps_vendor_id];
