ESI Calculation

The Employees’ State Insurance (ESI) is the largest need-based insurance scheme for Indian employees governed by the Employees’ State Insurance Act, 1948. It is managed by the Employees’ State Insurance Corporation (ESIC) and is designed to provide socio-economic protection to workers, their immediate families, and dependents.

This scheme provides medical care, cash benefits, and financial protection to employees in uncertain or difficult times. Since both employers and employees make contributions, understanding the ESI calculation and the ESI formula is essential to ensure correct deductions and filings.

This blog explains the ESIC calculation process, the formula used, and provides examples to make the concept of ESI contributions simple.

Wages as per the ESI Act

According to the Employees’ State Insurance (ESI) Act, all establishments with 10 or more employees are covered under ESI. This applies to factories, shops, and other establishments unless specifically exempted.

All employees whose wages do not exceed ₹21,000 per month (₹25,000 for specially abled employees) are eligible for coverage under the scheme, provided their organisation is covered under the ESI scheme.

If the salary goes above the limit, coverage stops, but if it falls within the limit in any month, benefits continue for that period.

ESI Calculation Formula

The ESIC decides the contribution rates for ESI and may change them from time to time. As per the latest revision to the ESIC Act, 1948, effective from 1st July, 2019, the employer contributes 3.25% of the gross salary, and the employee contributes 0.75% of the gross salary.

Employees earning a daily average wage of up to ₹176 are exempt from paying their contribution. However, the employer is still required to pay their share.

The ESI calculation formula is:

ESI Amount Calculation = (Gross Wages × Employer Rate) + (Gross Wages × Employee Rate)

For accurate deductions, the ESI formula is applied to the employee’s gross monthly wages, which include all allowances but exclude employer contributions to PF/ESI. This ESI formula ensures that contributions are calculated fairly across different wage structures.

Gross Wages are calculated by adding basic pay and allowances such as DA, HRA, Medical, and City Compensatory Allowance, etc. The final contribution amount is derived by adding the employer’s and employee’s shares.

How to Calculate ESI with Example

Based on the above section, let us now understand the ESI calculation through an example.

Suppose an employee, Mr. Rajesh Khanna, is earning monthly wages of ₹19,000 (Basic Pay + Allowances). As per the ESI Act, 1948, the ESI amount calculation is as follows:

Contributor Wages Considered Contribution Rate Example on ₹19,000
Employer ₹19,000/month 3.25% ₹617.50
Employee ₹19,000/month 0.75% ₹142.50
Employee (if wages > ₹21,000) Above ₹21,000/month No contribution Not applicable

In this example, for Mr. Rajesh Khanna, who earns ₹19,000 per month, the employer contributes ₹617.50 and the employee contributes ₹142.50. According to the ESI calculation, the total contribution deposited in the ESI fund is ₹760 per month (usually rounded to the nearest rupee as per payroll practice).

Contribution Period and Benefit Period

ESIC divides the year into two contribution periods and two benefit periods. Each contribution period has a corresponding benefit period in the following year. This means that contributions made in one period allow employees to claim benefits in the next period.

Contribution Period Benefit Period
1st April – 30th September 1st January – 30th June
1st October – 31st March 1st July – 31st December

This system also covers employees whose wages rise above ₹21,000 during the contribution period. Their contributions continue until the end of that period, and they remain eligible for benefits during the corresponding benefit period.

Let Us Consider Two Examples to Understand this Clearly:

Name Salary Revision Contribution Period Benefit Period
Mrs. Rachna Shah July 2020 1st April – 30th September 2020 1st January – June 2021
Mr. Ankit Tiwari November 2020 1st October 2020 – 31st March 2021 1st July – 31st December 2021
  • In the first example, Mrs Rachna Shah’s wages crossed ₹21,000 in July, but ESI deduction continued till September, keeping her covered until June 2021.
  • In the second example, Mr Ankit Tiwari’s wages crossed ₹21,000 in November, so the deduction continued till March 2021, giving him benefits until December 2021.

Advantages of Being an ESIC Member

The benefits of signing up for this Employees’ State Insurance Scheme (ESIC) are numerous. A few of them are mentioned below:

Sickness Benefit

Employees receive 70% of their wages for a maximum of 91 days in any year during certified illness.

ESI Contribution Collection Process

Employers can make the payment online through the official ESIC portal by using payment methods like net banking, UPI, or debit/credit cards. If not, the offline mode of payment is also available through SBI Bank or at any other authorised bank.

ESI Contribution Process

Employers covered under the ESI Act must register their establishment with the Employees’ State Insurance Corporation (ESIC) to pay the ESI contributions and file returns.

Here are the steps:

Step 1: Registration Process

The process starts with registering with the ESCI portal. The steps for registration are as follows:

Visit the ESIC official website.

Fill out Form 1 online to register the establishment.

Submit all required business and employee details.

After verification, ESIC issues a 17-digit unique code number that is required for all filings.

Each employee receives an ESI card after registration with their personal details.

Step-2: Documents Required for ESI Registration

Under the ESIC Act, 1948, employers need to submit the following documents to register with ESIC:

Business address proof

PAN card of the business

Details of all directors, partners, and shareholders

License under the Factories Act or the Shop & Establishment Act

Founding documents based on entity type, such as Articles of Association, Memorandum of Association, partnership deed in case of a partnership, and Limited Liability Partnership

Employee details, including their salary structure

Bank account details

Step-3: Filing ESI Returns

On successful registration, employers must follow the procedure below to file ESI returns online:

Log in to the official ESIC portal by entering the credentials received at the time of registration.

Select “File Monthly Contributions” from the menu.

Enter month, year, and contribution details, and then click on the ‘Submit’ button.

Next, go to the ‘List of Actions’ and click ‘Generate Challan’. Generate and download the challan for records and inspections.

Step-4: Deadlines for Filing ESI Returns

The deadline for filing ESI returns for both periods is as follows:

Contribution Period Deadline
1st April to 30th September 12th November
1st October to 31st March 12th May

Step-5: Penalties for Non-Payment or Late Payment

Statutory Compliance in HR and Payroll is essential to avoid penalties or legal actions. Employers are legally responsible for depositing the amount deducted from an employee’s pay as the employee’s ESI contribution on time. Any non-payment, late payment, or false payment is a punishable offence under the ESI Act.

Employers are punishable for up to 2 years in prison and a penalty of Rs. 5000.

Employers must also pay an interest of 12% per annum for each day of delay or default in payment.
