What Is ESI?
ESI stands for Employee State Insurance. It is a statutory social security scheme administered by the Employees' State Insurance Corporation (ESIC), a body set up under the ESI Act of 1948. The scheme provides insured workers and their dependents access to medical care, maternity benefits, disability compensation, and other welfare provisions funded through monthly contributions from both the employer and the employee.
The scheme is not optional for covered establishments. Once an organization crosses the applicability threshold, registration and timely remittance of contributions become a legal obligation.
Who Must Register Under ESI?
The ESI Act applies to factories and establishments where 10 or more persons are employed. Employees whose gross monthly wages do not exceed ₹21,000 are covered under the scheme. For employees with disabilities, the wage ceiling is ₹25,000 per month.
| Parameter | Threshold |
|---|---|
| Minimum employees for applicability | 10 or more |
| Wage ceiling (general employees) | ₹21,000 per month (gross) |
| Wage ceiling (employees with disabilities) | ₹25,000 per month (gross) |
| Governing legislation | ESI Act, 1948 |
| Administering body | ESIC (Employees' State Insurance Corporation) |
ESI Contribution Rates
The current contribution rates have been in effect since July 2019, when the government reduced them to ease the burden on both employers and employees.
How to Calculate ESI Contribution
The calculation is applied on gross wages, which includes basic salary, dearness allowance, house rent allowance, and any other regular allowances. Overtime wages are excluded from the ESI wage base.
Step-by-Step Calculation Example
Assume an employee has a gross monthly salary of ₹18,000.
-
Check eligibility₹18,000 is below the ₹21,000 ceiling, so ESI applies to this employee.
-
Calculate employee contribution₹18,000 × 0.75% = ₹135
-
Calculate employer contribution₹18,000 × 3.25% = ₹585
-
Total ESI remittance₹135 + ₹585 = ₹720 deposited with ESIC by the 15th of the following month.

Contribution Periods

|---|---|
| 1 April to 30 September | 1 January to 30 June (following year) |
| 1 October to 31 March | 1 July to 31 December (same year) |
What Is Included in Gross Wages for ESI?
