The present wage ceiling under the ESI Act, 1948 is Rs. 15,000 per month. It has not been enhanced so far. The issue will be decided by the appropriate government, i.e., the Ministry of Labour & Employment, Government of India. The notification of their intention to enhance such a wage ceiling has not been issued yet. As and when you desire, I suggest you confirm the position from the nearest office of ESIC to be sure on the subject.
