ESI Contribution

ESI contribution in respect of an employee comprises both the employer’s contribution and the employee’s contribution. The contribution rates are fixed and are revised from time to time. The latest Employer’s ESI contribution rate in 2024 is 3.25% of the wages payable to the employee. While the employee’s ESI contribution percentage 2024 is at 0.75% of the wage. Furthermore, in case the daily average wage of an employee is up to INR 137, they are exempt from the contribution payment. However, employers have to pay their contribution to such employees.

How to Calculate ESI with Example?

The ESI contributions are based on the wages paid to the employees. The employer and employee ESI contributions are as follows:

  • ESI Employer’s Contribution Rate: 3.25% of the payable wages
  • ESI Employees Contribution Rate: 0.75% of the payable wages

ESI Calculation Formula

Total ESI Contribution = Employer’s Contribution + Employees Contribution

How to Calculate ESI for Rs. 15000 Salary

Let’s understand the ESI contribution calculation with an example. Let’s Mr Anuj works in an establishment that qualifies under the ESI Act. The monthly wage for Mr Anuj is INR 15,000. The contribution towards the Employee State Insurance Scheme is as follows:

Employer Contribution = INR 15,000 * 3.25% = INR 487.50

Employee Contribution = INR 15,000 * 0.75% = INR 112.50

Total ESI Contribution = 487.5 + 112.5 = INR 600

Employee State Insurance Contribution Collection

An employer is responsible for paying his contribution for each employee and deducting employee contributions from wages bills. Furthermore, the employer must pay the contributions to the Corporation within 15 days of the last day of the calendar month in which the contributions are due.

The Corporation has authorised certain State Bank of India branches and a few other banks to accept payments on its behalf.

Contribution Period and Benefit Period

Under the ESI scheme, the contribution period is 6-month. Therefore, there are two contribution periods in a year. Furthermore, there is a corresponding benefit period of a 6-month duration for each contribution period. Following are the contribution periods and their corresponding benefit period:

  • For the contribution period from 1st April to 30th September, the corresponding cash benefit period is 1st January of the following year to 30th June.
  • For the contribution period from 1st October to 31st March of the following year, the corresponding cash benefit period is 1st July to 31st December.

The contribution period concept benefits an employee whose salary increases beyond the threshold limit.

For example, if your salary was INR 20,000 in May 2022, and from June 2022, it becomes INR 23,000. The contributions till 30th September 2022 will be considered on the revised salary of INR 23,000 for ESI calculation purposes. Post which, you will not qualify for the ESI contribution. Since the salary threshold is INR 21,000. However, you will be eligible for the corresponding benefit period (1st January 2023 to 30th June 2023).
