Please find below the relevant portion of the act:
4A. COMPULSORY INSURANCE. - (1) With effect from such date as may be notified by the appropriate Government, every employer, other than an employer or an establishment belonging to, or under the control of, the Central Government or a State Government, shall, subject to the provisions of sub-section (2), obtain insurance in the manner prescribed for his liability for payment towards gratuity under this Act, from the Life Insurance Corporation of India established under the Life Insurance Corporation of India Act, 1956 (31 of 1956) or any other prescribed insurer. Provided that different dates may be appointed for different establishments or class of establishments or for different areas.
(2) The appropriate Government may, subject to such conditions as may be prescribed, exempt every employer who has already established an approved gratuity fund for his employees and who desires to continue such an arrangement, and every employer employing five hundred or more persons who establishes an approved gratuity fund in the manner prescribed from the provisions of sub-section (1).
(3) For the purpose of effectively implementing the provisions of this section, every employer shall, within the time prescribed, get his establishment registered with the controlling authority in the prescribed manner. No employer shall be registered under the provisions of this section unless he has taken an insurance referred to in sub-section (1) or has established an approved gratuity fund referred to in sub-section (2).
(4) The appropriate Government may, by notification, make rules to give effect to the provisions of this section. Such rules may provide for the composition of the Board of Trustees of the approved gratuity fund and for the recovery by the controlling authority of the amount of gratuity payable to an employee from the Life Insurance Corporation of India or any other insurer with whom insurance has been taken under sub-section (1), or, as the case may be, the Board of Trustees of the approved gratuity fund.
(5) If an employer fails to make any payment by way of premium to the insurance referred to in sub-section (1) or by way of contribution to an approved gratuity fund referred to in sub-section (2), he shall be liable to pay the amount of gratuity due under this Act (including interest, if any, for delayed payments) forthwith to the controlling authority.
