How to Apply for ESI Registration Online (Step by Step ESIC Process)

Every employer in India with 10 or more employees (in notified areas) must register with the Employees' State Insurance Corporation (ESIC) under the Employees' State Insurance Act, 1948. Registration is done online through the ESIC portal at esic.gov.in, costs nothing, takes 7 to 15 working days, and results in a 17-digit ESIC Code. ESI provides comprehensive social security to employees earning up to ₹21,000 per month, covering free medical care for the employee and their family, sickness benefit at 70% of wages, 26 weeks of maternity benefit, disability pension, and dependants' benefits.

This guide covers the complete ESI registration process for employers in 2026: checking applicability, preparing documents, filling the online form, generating employee Insurance Numbers, filing monthly contributions, and understanding your ongoing compliance obligations.

What is ESI Registration?

ESI registration is the process of registering an establishment with the Employees' State Insurance Corporation (ESIC) under the Employees' State Insurance Act, 1948, making the employer legally responsible for deducting and depositing ESI contributions for all eligible employees earning up to ₹21,000 per month. The registration results in the allotment of a 17-digit ESIC Code that serves as the employer's unique identifier for all ESI-related transactions, filings, and correspondence.

The ESI scheme is India's oldest social security programme for workers, started in 1952 with the first dispensary in Kanpur. It now covers over 3.6 crore insured persons and 13.5 crore beneficiaries (including family members) across 36 states and Union Territories. The scheme provides a comprehensive package of medical, cash, maternity, disability, and survivors' benefits, funded jointly by employers and employees. ESIC operates 159 hospitals, over 1,500 dispensaries, and has tie-ups with thousands of empanelled private hospitals to deliver healthcare services.

Who Needs ESI Registration? Applicability Rules

ESI applicability depends on three factors: the type of establishment, the number of employees, and whether the establishment is located in a notified area. Understanding these rules is critical to avoid penalties for non-registration.

Mandatory Registration Threshold

The ESI Act applies to all establishments employing 10 or more persons in areas where the ESI scheme has been notified and implemented. In certain states, the threshold remains at 20 employees. The count includes all employees regardless of their wage level: even if some employees earn above ₹21,000 and are not personally covered by ESI, they are counted towards the threshold. Contract workers, part-time staff, trainees, and probationers are all included in the headcount.

Types of Covered Establishments

The ESI Act covers a wide range of establishments beyond just factories. The following are explicitly covered:

• Factories under Section 2(12) of the Factories Act, 1948
• Shops and commercial establishments as defined under state-specific Shop and Establishment Acts
• Hotels and restaurants not having any manufacturing activity
• Cinemas, theatres, and preview theatres
• Road motor transport undertakings
• Newspaper establishments including editing, printing, and distribution
• Private educational institutions
• Private medical institutions
• Any other class of establishments notified by the Central or State Government

ESI Employee Coverage: ₹21,000 Wage Limit

Only employees earning gross monthly wages up to ₹21,000 are covered under the ESI scheme. For persons with disability, the limit is ₹25,000 per month. Gross wages include basic pay, dearness allowance, HRA, city compensatory allowance, incentives, and all other regular allowances. Overtime earnings are the only component excluded from the gross wage calculation for ESI purposes.

ESI Contribution Rates in 2026

These rates were effective from 1 July 2019, reduced from the previous rates of 4.75% (employer) and 1.75% (employee). The reduction was made to increase take-home pay for employees and reduce employer burden.

Low-Wage Employee Exemption

Employees earning gross daily wages of ₹176 or less (approximately ₹5,280 per month) are exempt from the employee contribution of 0.75%. For these low-wage employees, only the employer contributes 3.25%, and the employee's contribution is nil. This exemption ensures that the lowest-paid workers do not have any deduction from their already limited wages.

Contribution Calculation Example

Documents Required for ESI Registration

1. PAN Card of the Establishment -- Corporate PAN issued to the company, LLP, or firm. Verified against the Income Tax database during registration
2. Certificate of Incorporation / Registration Certificate -- Issued by MCA for companies and LLPs, or by the Registrar of Firms for partnership firms. Shows the entity name, date of incorporation, and CIN/LLPIN
3. Address Proof of Business Premises -- Rent agreement (notarised or registered), lease deed, property tax receipt, or utility bill (electricity or water) of the establishment address
4. Cancelled Cheque -- From the current account of the establishment, showing the entity name, account number, IFSC code, and MICR code
5. Employee Details -- Full name, date of birth, date of joining, Aadhaar number, monthly gross wages, bank account details, and nominee information for each employee
6. Director/Partner Details -- Name, DIN or DPIN, PAN, Aadhaar, residential address, and mobile number of all directors or partners
7. Family Details of Employees -- Name, date of birth, relationship, and Aadhaar (if available) of spouse, children, and dependent parents for each employee, as ESI covers the entire family

Step-by-Step ESI Registration Process on the ESIC Portal

The complete registration process is done online through the ESIC portal at esic.gov.in. Total steps: 8. Estimated time: 7 to 15 working days. Cost: ₹0.

Step 1: Check ESI Applicability

Before starting, verify that your establishment meets the applicability criteria. Count all employees including contract workers, part-time staff, and trainees. Check if your establishment location falls in an ESIC-notified area (almost all urban and semi-urban areas in India are now notified). If your total headcount crosses 10, ESI registration is mandatory regardless of how many employees earn above or below the ₹21,000 wage limit.

Step 2: Visit the ESIC Portal and Create an Employer Account

Go to esic.gov.in and navigate to the Employer section. Click on 'Sign Up' or 'New Employer Registration'. Enter the employer name (as per PAN), email address, and mobile number. Verify your email and mobile through OTP. Set a secure password. After account creation, log in to access the employer registration form. Government entities and PSUs may use separate registration modules available on the portal.

Step 3: Fill Employer Registration Form (Form 01)

Complete the online Employer Registration Form 01 with the following details: establishment legal name, PAN, date of commencement of business, registered address (state, district, city, pin code), nature of business activity with NIC code, total number of employees as of the application date, and the date on which the establishment first employed the threshold number of employees. Select the ESIC branch office jurisdiction based on your establishment location.

Step 4: Enter Director/Partner and Authorised Signatory Details

Add the details of all directors (for companies), designated partners (for LLPs), or partners (for partnership firms). Enter name, DIN or DPIN, PAN, Aadhaar, date of birth, residential address, email, and mobile number for each person. Designate one person as the authorised signatory for ESI operations. The authorised signatory's mobile number will receive OTPs for future transactions on the portal.

Step 5: Enter Employee Details and Family Information

Add each employee eligible for ESI coverage (earning up to ₹21,000 gross wages). Enter: full name as per Aadhaar, date of birth, date of joining, Aadhaar number, gender, marital status, monthly gross wages, bank account with IFSC, and nominee details. For each employee, also add family member details: spouse name, children's names and dates of birth, and dependent parents. ESIC uses this data to generate IP Numbers and Pehchan Cards for the employee and their family members.

Step 6: Upload Supporting Documents

Upload the establishment PAN card, Certificate of Incorporation, address proof, and cancelled cheque in PDF or JPEG format. Ensure all files are under the portal's size limit (typically 2 MB per document). The PAN is verified against the Income Tax database, and the bank account is verified electronically. If any document verification fails, the portal will display an error message with specific instructions for correction.

Step 7: Submit the Application

Review all entered data thoroughly. Once submitted, corrections to certain fields (like PAN or establishment name) become difficult and may require a fresh application. Click Submit. The portal generates an application reference number and sends a confirmation email. The ESIC regional office reviews the application, conducts any necessary verification, and processes the registration. The typical processing time is 7 to 15 working days.

Step 8: Receive ESIC Code and Generate Employee IP Numbers

Upon approval, ESIC allots a 17-digit ESIC Code to your establishment and sends it via email. Log in to the ESIC employer portal using the ESIC Code and password. Navigate to the Employee section and generate Insurance Person (IP) Numbers for each employee. The IP Number is the employee's unique ESI identity that they use for life, similar to the UAN in EPF. Request Pehchan Cards for employees and their family members for accessing ESIC medical facilities.

ESI Benefits for Employees: Complete Breakdown

ESI provides 6 distinct benefits to covered employees and their families. Understanding these benefits helps employers communicate the value of ESI compliance to their workforce.

Monthly ESI Compliance: Contribution Filing Process

After registration, the employer must file the monthly contribution challan and make payment by the 15th of each month for wages paid in the previous month.

Monthly Filing Steps

1. Log in to the ESIC employer portal with your 17-digit ESIC Code and password
2. Navigate to Contribution > Monthly Contribution (MC)
3. Enter the contribution month and year
4. The portal auto-populates the list of registered employees. Enter the number of days worked and wages paid for each employee during the month
5. The system calculates the employer (3.25%) and employee (0.75%) contributions automatically
6. Review the summary, generate the challan, and make payment through internet banking, NEFT/RTGS, or the SBI collect payment gateway
7. After successful payment, download the challan receipt as proof of payment

Late Payment Consequences

ESI Contribution Periods and Benefit Periods

The ESI scheme operates on a 6-month cycle. Understanding the relationship between contribution periods and benefit periods is important for both employers and employees.

An employee must have at least 78 days of contribution in a contribution period to qualify for cash benefits (sickness, maternity) in the corresponding benefit period. Medical benefits are available from day 1 of coverage without any minimum contribution requirement. Disablement and dependants' benefits are also available from day 1.

Common Issues in ESI Registration and How to Resolve Them

ESIC Portal Technical Errors

The ESIC portal occasionally experiences downtime or slow response during heavy traffic periods, especially in the first week of the month and during annual return filing deadlines. If you encounter technical errors, try accessing the portal during off-peak hours (early morning or late evening). Clear your browser cache, use Chrome or Firefox (not Internet Explorer), and disable any ad-blocker extensions. If the issue persists for more than 24 hours, raise a ticket on the ESIC grievance portal at pgportal.gov.in.

Aadhaar Verification Failure for Employees

Employee Aadhaar validation against UIDAI is real-time. If the employee name or date of birth in the ESIC form does not match the Aadhaar records exactly (even minor spelling differences), the verification fails. The employee must update their Aadhaar details at the nearest enrolment centre, or the employer must enter the name exactly as it appears on Aadhaar including any spelling variations.

ESIC Code Not Received After 15 Days

If the ESIC Code is not received within 15 working days, check the application status on the ESIC portal. If the status shows pending, file a grievance on the ESIC Atal Grievance Portal (atalgrievance.esic.gov.in) with the application reference number and supporting documents. You can also visit the nearest ESIC branch office in person during working hours for follow-up.

Employee Wage Crosses ₹21,000 After Registration

When an employee receives a salary increment that pushes their gross wages above ₹21,000, they continue to be covered until the end of the current contribution period. From the next contribution period, the employer stops deducting ESI for that employee. Update the employee status in the ESIC portal to reflect the changed wage level. The employee retains benefit eligibility for the corresponding benefit period even after exiting ESI coverage.
