Clarity exists in proviso to Para 26 A (2) of the EPF Scheme, extracted below:
26A. Retention of membership
(1) A member of the Fund shall continue to be member until he withdraws under
paragraph 69 the amount standing to his credit in the Fund or is covered by a
notification of exemption under section 17 of the Act or an order of exemption under
paragraph 27 or paragraph 27A.
(2) Every member employed as an employee other than an excluded employee,
in a factory or other establishment to which this Scheme applies, shall contribute to
the Fund, and the contribution shall be payable to the Fund in respect of him by the
employer. Such contribution shall be in accordance with the rate specified in
paragraph 29:
Provided that subject to the provisions contained in sub-paragraph (6) of paragraph
26 and [in paragraph 27], or sub-paragraph (1) of paragraph 27- A, where the
monthly pay of such a member exceeds [fifteen thousand rupees] the contribution
payable by him, and in respect of him by the employer, shall be limited to the
amounts payable on a monthly pay of [fifteen thousand rupees]
So from this sub-para it is evident that once an employee is covered under the EPF Scheme, he/she will continue to be so upto the ceiling amount, even if the salary exceeds such limit.
Hope this clarifies.
