See Director prima facie is an Agent of the company. Now if you are paying anything above the sitting fees, that is the director's remuneration. Then the director becomes employee of the company as then he is working more then what he is supposed to do as director for which only sitting fees is paid. So if someone is paid any remuneration he is an employee irrespective of his being director. So if you have paid that person remuneration and he is covered under PF, you need to deduct and submit PF.
