See if changing the ot_shipping.php module around line 35 for the IF to:
works better for you on the tax issue ...Code:if ( ($pass == true) && ( ($order->info['total'] - $order->info['shipping_cost'] - $order->info['tax']) >= MODULE_ORDER_TOTAL_SHIPPING_FREE_SHIPPING_OVER) ) {
This is not a complete fix, but can work in many circumstances ...
