ESI (Employee State Insurance) is a self-financing social security and health insurance scheme that provides medical care, sickness benefits, maternity benefits, disability benefits, and dependants' benefits to employees in covered establishments and their families. Under Indian law, it is established and governed by the Employees' State Insurance Act, 1948 and administered by the Employees' State Insurance Corporation (ESIC), an autonomous body under the Ministry of Labour and Employment.
Legal definition
The Employees' State Insurance Act, 1948 establishes a comprehensive social security framework through the following key provisions:
Section 1(4): The Act applies, in the first instance, to all factories (including factories belonging to the Government) other than seasonal factories.
Section 2(12): "Employee" means any person employed for wages in or in connection with the work of a factory or establishment to which this Act applies.
Section 38 — All employees to be insured: Subject to the provisions of this Act, all employees in factories or establishments to which this Act applies shall be insured in the manner provided by this Act.
Applicability thresholds: The ESI Act applies to non-seasonal factories and establishments with 10 or more employees (reduced from 20 by notification in several states). The wage ceiling for coverage is Rs 21,000 per month — employees drawing wages up to this threshold are mandatorily covered.
Contribution rates: The employer contributes 3.25% and the employee contributes 0.75% of wages (total 4%). Employees earning up to Rs 176 per day are exempt from the employee's contribution, with the employer bearing the full cost.
New law equivalent: The Social Security Code, 2020 proposes to subsume the ESI Act under Chapter IV (Sections 29-43), extending ESI coverage to establishments with as few as 10 workers and potentially including gig workers, platform workers, and unorganised sector workers.
How courts have interpreted this term
ESIC v. Francis De Costa [(1995) 6 SCC 1]
The Supreme Court held that the ESI Act is a beneficial social security legislation and must be interpreted liberally to advance its protective purpose. The Court ruled that an employee who suffers an injury arising out of and in the course of employment is entitled to disablement benefit even if the injury occurs outside the factory premises, provided it has a nexus with the employment. The Court established a broad interpretation of "arising out of employment" that encompasses risks incidental to the employment.
Royal Western India Turf Club Ltd. v. ESIC [(1953] SCR 571)
The Supreme Court upheld the constitutional validity of the ESI Act and held that the compulsory contribution by employers constitutes a valid exercise of legislative power under Entry 23 of the Concurrent List (social security and social insurance). The Court rejected the argument that the employer's contribution is an unconstitutional exaction, characterising it as a social security contribution authorised by the Constitution.
M/s Bangalore Turf Club v. ESIC [(2014) 9 SCC 657]
The Supreme Court clarified the concept of "wages" under Section 2(22) of the ESI Act, holding that all remuneration paid to employees — whether as basic wages, dearness allowance, house rent allowance, or other allowances — that constitutes regular remuneration is included. Only amounts expressly excluded by the provision (such as contributions to provident fund, retrenchment compensation, and gratuity) fall outside the definition of "wages" for ESI contribution purposes.
Types of ESI benefits
The ESI Act provides six categories of benefits:
- Medical benefit (Section 56): Full medical care for the insured employee and their family members at ESI dispensaries, hospitals, and empanelled facilities, from the date of joining.
- Sickness benefit (Section 49): Cash compensation during certified sickness at the rate of 70% of wages for a maximum of 91 days in two consecutive benefit periods. Extended sickness benefit at 80% of wages for up to two years for specified long-term diseases.
- Maternity benefit (Section 50): Cash compensation for 26 weeks (extended from 12 weeks by the 2017 amendment) at full wage rate, available to insured women or the wife of an insured person.
- Disablement benefit (Section 51-51A): Temporary disablement benefit at 90% of wages for the full period of disablement; permanent disablement benefit as a periodic pension based on the extent of disability.
- Dependants' benefit (Section 52): Monthly pension to dependants of an insured person who dies as a result of employment injury, at 90% of wages distributed among eligible dependants.
- Funeral expenses (Section 52A): A lump sum of Rs 15,000 to the eldest surviving family member or the person who bears the funeral expenses.
Why this matters
The ESI scheme is India's most comprehensive social health insurance programme, covering over 14 crore beneficiaries (insured persons plus their family members) as of 2025. For a large portion of the formal-sector workforce, ESI provides the only access to cashless medical treatment, income protection during illness, and compensation for workplace injuries.
For employers, ESI registration and compliance is mandatory once the establishment meets the applicability threshold. The employer must register within 15 days of the Act becoming applicable, deduct the employee's share from wages, and deposit both shares within 15 days of the following month. Non-compliance triggers substantial penalties: Section 85 prescribes imprisonment up to two years and a fine up to Rs 5,000 for non-payment, and Section 85A authorises ESIC to recover arrears as land revenue.
For employees, the practical significance lies in the breadth of coverage: the insured person and all family members (spouse, children, and dependent parents) receive cashless medical treatment at ESI hospitals and dispensaries across India. The sickness benefit provides income replacement during periods of certified illness, and the disablement benefit provides long-term income security for workplace injuries.
A common concern is the quality of medical infrastructure at ESI facilities. While ESI hospitals have historically faced criticism for inadequate infrastructure, the ESIC has progressively expanded its network to over 1,500 dispensaries and 160 hospitals, and has also empanelled private hospitals to supplement its own facilities.

Frequently asked questions
Who is eligible for ESI benefits in India?
All employees drawing wages up to Rs 21,000 per month in establishments covered under the ESI Act (factories and notified establishments with 10 or more employees) are mandatorily covered. The insured person's family members — including spouse, children up to 25 years of age, and dependent parents — are also entitled to medical benefits. There is no minimum service requirement for medical benefits; coverage begins from the date of joining.
What is the contribution rate for ESI?
The employer contributes 3.25% and the employee contributes 0.75% of wages to the ESI fund, for a total of 4%. Employees earning up to Rs 176 per day are exempt from their 0.75% contribution. The contributions are computed on all wages (basic pay, dearness allowance, and other allowances) as defined under Section 2(22) of the Act.
Can an ESI-covered employee go to a private hospital?
Yes, but with conditions. For routine and planned treatment, insured persons must use ESI dispensaries, hospitals, or ESIC-empanelled facilities to avail of cashless treatment. In emergencies, treatment at non-empanelled private hospitals is permissible, and ESIC may reimburse the expenses subject to verification. The ESIC has also entered into tie-up arrangements with several private hospital chains to expand access.
What happens if an employer does not register under ESI?
An employer who fails to register under the ESI Act when the establishment meets the applicability criteria is liable for penalties under Sections 85 and 85A, including imprisonment up to two years and a fine up to Rs 5,000. Additionally, the ESIC can retrospectively assess and recover contributions for the entire period of default, along with interest and damages. The employer also becomes personally liable for any medical expenses incurred by employees who would have been covered.
