Pf contribution by employer -urgent

• Employers can apply for exemption in respect of a class of employees getting similar or better benefits than the statutory P.F. Scheme under P. 27A  subject to the conditons  governing grant of exemption. 
• The  employer can seek exemption from P.F. Scheme for the entire establishment if the majority of the employees also consent for exemption, subject to certain  conditions governing grant of exemption and certain formalities.

Do we need to intimate labour officer and PF office that we donnot want to pay PF to employees
