I found an answer for this question,

$customer_tax_class = '5';
        $rates = $tax->load($customer_tax_class, 'customer_tax_class_id');
        $request = Mage::getSingleton('tax/calculation')->getRateRequest()->setProductClassId(2)->setCustomerClassId(5);
        echo $percent = Mage::getSingleton('tax/calculation')->getRate($request);
