Just some initial digging... In GC mod's response handler (appropriately named responsehandler.php) there are several references to taxes. Examples:
Code:
$tax_amt = $data[$root]['order-adjustment']['total-tax']['VALUE'];
...
$order->info['tax'] = $tax_amt;
...where $root and $data come from parsed XML. There are also some lines about taxes in invoice generation parts of the same file, but I'm not entirely sure about them yet. I wonder if we can override the line that sets $tax_amt? The address details seem to be there too, according to nearby code.
