Factories and most shops, hotels, restaurants, transport and other notified establishments with 10 or more employees, in areas where ESIC has implemented the scheme.
What if an employee's salary crosses ₹21,000 during the year?
Contributions continue until the end of the current contribution period (April–September or October–March), then stop.
