The PF Act does not restrict the contribution amount, but the employer is not legally bound to pay the PF contribution above 12% of ₹6,500 Basic + DA (i.e., ₹780).
Explanation:
1. If both the employer and employee are willing to contribute more than ₹780, they can do so.
2. If an employee wishes to contribute 100% of their basic salary, but the employer does not agree, then the employer can pay only 12% of the basic salary up to the ceiling of ₹6,500 (Ceiling Value effective from 1/6/2001), as the employer is not legally obligated to pay more than that.
