When ESI Coverage Applies
ESI becomes mandatory under the ESI Act, 1948 when an establishment employs 10 or more persons — a lower threshold applies in some states and for hazardous industries — and those employees earn gross monthly wages not exceeding Rs. 21,000, or Rs. 25,000 for persons with disabilities. The wage ceiling is calculated on gross wages, including basic pay, dearness allowance, house rent allowance, city compensatory allowance, overtime and other regular cash allowances, not on basic pay alone, and contract or temporary workers deployed at the premises count toward the 10-employee threshold.
Contribution Rates and What Employees Get
Current contribution rates are 3.25% of wages from the employer and 0.75% from the employee, remitted monthly along with the ESI return. Registration provides covered employees with medical, sickness, maternity and disablement benefits administered by ESIC — a meaningful benefit for employees earning within the wage ceiling, and a compliance obligation employers should not underestimate in scope.
The Move Toward Unified Registration
The Code on Social Security, 2020, in force from 21 November 2025, intends a single unified electronic registration for EPF, ESI and other social security schemes, and ESIC has separately mandated registration compliance by employers with a deadline around 31 December 2025. Employers should confirm the current registration procedure against the live ESIC and Shram Suvidha portal, since the exact mechanics have been phased in over time.
Ongoing Obligations
Beyond monthly contribution remittance, covered employers must maintain statutory registers and file half-yearly returns. Non-compliance carries interest, damages and potential prosecution under the ESI Act — the wage ceiling of Rs. 21,000 has not changed since January 2017, making it a frequently outdated figure in older guides, so employers should confirm the current figure rather than relying on an older source.
