Dear Saiyad Waseem,
If the Board of Directors are Members of Provident Fund, you must be deducting Provident Fund Contributions from their remunerations. And if so, naturally you are paying matching employer's contribution to PF.
The employer's contribution which you pay on behalf the employees, takes care of Employees Family Pension part which is maximum 8.33% of Rs.15,000/- i.e. Rs.1,250/- and rest amount credited to employees PF account.
Regards,
Suresh
