ESI: the medical cover behind a wage deduction
ESI, the Employees' State Insurance, is a contributory scheme under the Employees' State Insurance Act, 1948 that gives covered workers medical care and cash benefits during sickness, injury and maternity. Both the employee and the employer contribute a share of wages every month. The scheme delivers treatment through its own hospitals and dispensaries.

Also called: ESI, ESIC, employees state insurance
In plain English
A small part of wages goes into a government health scheme every month, and the company adds its share. In return the worker and their family get treated at scheme hospitals.
How it works in detail
Coverage runs through the establishment first. A unit in a notified area with enough employees comes under the Act, and once it is covered, employees earning up to the wage limit fixed under the scheme are covered individually. That limit, the two contribution shares and the contribution periods are set by the rules and revised, so ask your consultant to confirm the current figures before you process a month.
The benefit side is what an employee actually sees. A covered worker gets treatment for themselves and their dependants at scheme hospitals and dispensaries, cash during certified sickness, maternity benefit, and compensation after an injury at work. The contribution is worked out on the wages actually paid for the month, so a month with unpaid days carries a smaller figure. Your accountant computes it and files the return.
A worked example
The setup
Suppose Nazia is a covered machine operator on INR 17,400 gross a month. She has two unpaid days in October, and her accountant supplies the contribution figure.
The calculation
The share here is assumed for the example and is no statutory rate. INR 17,400 / 30 = INR 580.00 a day, so 2 unpaid days come to INR 1,160.00 and wages paid are INR 16,240.00. The accountant returns an employee share of INR 122.00.The result
Nazia is paid INR 16,118.00 before any other deduction, and her slip shows 28 days paid with the insurance line. Her card covers treatment for her family at the dispensary.
Common mistakes
- Stopping the deduction the month an employee's wages cross the limit. The rules run contributions to the end of the contribution period, so ask your consultant when the deduction actually stops.
- Leaving a new joiner off the return because the registration paperwork is pending. Coverage starts with the employment, and a worker without a card gets turned away at the dispensary when they need it.
- Assuming a contract worker on your premises is somebody else's problem. Ask your consultant how workers engaged through a contractor are covered before you sign that contract.
How VTClock handles it
VTClock deducts no ESI contribution and files no ESI return. It records the days worked and the wages payable for the month, which is what your accountant needs.
Frequently asked questions
Which of my shop staff come under ESI and which stay outside it?
Coverage works in two steps. First the establishment has to fall under the Employees' State Insurance Act, 1948, which turns on where the unit sits and how many people it employs. Then, inside a covered unit, employees earning up to the wage limit fixed under the scheme are covered and those earning above it are outside. Both the headcount and the wage limit are set by the rules and get revised, so have your consultant check your unit against the current ones.
What does a worker actually get back for the amount taken off their wages?
The contribution buys service delivered through the scheme's own hospitals and dispensaries, where a covered worker and their dependants can be treated. On top of treatment the scheme pays cash during certified sickness, maternity benefit for women workers, and compensation after an injury caused by the employment. None of it comes back as a lump sum the worker can withdraw, which is where it differs from provident fund.
An employee got a raise mid-year. Does the deduction stop from that month?
No. Contributions run in fixed contribution periods, and an employee covered at the start of a period stays covered until that period ends, even when their wages cross the limit part way through. Cutting the deduction off on the day of the raise leaves a gap in the return that has to be corrected later. Ask your consultant which period you are in and from which month the deduction correctly stops.
I already pay for a private health policy for my team. Do I still need ESI?
A private policy does not replace a statutory scheme. If your establishment is covered under the Employees' State Insurance Act, 1948 and an employee falls within the wage limit, the contribution is due whatever other cover you have bought. Plenty of employers run a group policy for staff above the wage limit and rely on the scheme for everyone below it. Your consultant can tell you which of your people sit on which side.
