What is ESI
ESI stands for Employee State Insurance. It is a statutory social security scheme run by the Employees' State Insurance Corporation under the ESI Act of 1948. The scheme gives insured workers and their dependents medical care, sickness benefit, maternity benefit, disability cover, and dependent benefit, funded by monthly contributions from the employer and the employee.
For a covered establishment, ESI is not elective. Once the headcount and wage thresholds are crossed, registration and timely remittance are 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 Rs 21,000 are covered. For employees with disabilities, the ceiling is Rs 25,000.
| Parameter | Threshold |
|---|---|
| Minimum employees for applicability | 10 or more |
| Wage ceiling, general employees | Rs 21,000 per month, gross |
| Wage ceiling, employees with disabilities | Rs 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 load on both sides.
How to calculate ESI contribution
The calculation runs 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.
Employer ESI = Gross Wages × 3.25%
Total ESI = Gross Wages × 4.00%
Step by step example
Assume an employee with a gross monthly salary of Rs 18,000.
- Check eligibilityRs 18,000 is below the Rs 21,000 ceiling, so ESI applies.
- Employee contributionRs 18,000 × 0.75% = Rs 135
- Employer contributionRs 18,000 × 3.25% = Rs 585
- Total remittanceRs 135 + Rs 585 = Rs 720, deposited with ESIC by the 15th of the following month.
