ESIC has amended Regulation 31 of ESI (General) Regulations, 1950, whereby the due date for the deposit of contributions has been changed to the 15th of the last day of the calendar month in which the contributions fall due. Previously, the deadline was the 21st. A copy of the notification uploaded by the department on its website is linked herewith: http://esic.nic.in/backend/writeread...310c93dd46.pdf
