As per Section 12 of the EPF & MP Act, you are not expected to reduce the PF qualifying salary. At the same time, if the present PF qualifying salary is above Rs 15,000, it can be brought down to Rs 15,000, but you cannot reduce it further. However, if the situation is so poor that the company cannot move ahead without a cost cut affecting the PF salary, you can try to convince the appropriate authorities. Since the statutory minimum wage is above Rs 15,000 in most of the scheduled employment, I don't feel it will be approved.
