What Is ESI and Who Must Register?

Employee State Insurance (ESI) is a self-financed social security scheme governed by the Employees' State Insurance Act, 1948, administered by the Employees' State Insurance Corporation (ESIC).

• Factories with 10 or more employees
• Shops, hotels, restaurants, road transport undertakings, newspapers, and other establishments notified by the government
• Employees drawing gross wages up to ₹21,000 per month (₹25,000 for persons with disability) are covered

ESIC Coverage Benefits:

1. 1Medical benefit for employee and family
2. 2Sickness cash benefit (70% of wages for up to 91 days/year)
3. 3Maternity benefit (26 weeks fully paid)
4. 4Disablement benefit
5. 5Dependent's benefit in case of death due to employment injury

Step-by-Step: Filing ESI Challan on the ESIC Portal

Step 1: Log In to the ESIC Employer Portal

Visit the ESIC employer portal and log in with your 17-digit ESIC employer code and password.

Step 2: Submit Monthly Wages and Attendance

Navigate to Monthly Contribution → Submit → New Contribution:

• Select the applicable contribution month
• Enter employee-wise gross wages and number of days worked
• The portal auto-calculates the employer's share (3.25%) and employee's share (0.75%)
• Review the total contribution amount carefully before final submission

Step 3: Generate the Challan

After submitting contributions:

• Click Generate Challan
• Note the Challan Reference Number (SRN)
• Download and save the challan PDF for your records

Step 4: Pay the Challan

Available payment options:

• SBI Net Banking or Debit Card via the ESIC portal payment gateway
• NEFT/RTGS using the SBI virtual account details printed on the challan
• Walk-in payment at designated SBI branches (uncommon for most employers today)

Step 5: Confirm Payment and Download Receipt

Log back into the ESIC portal → Challan Status → verify the status reads "Payment Successful". Download and store the paid challan as documentary proof for audits and ESIC inspections.

ESI Due Dates and Penalties for Late Payment

ESI contributions must be deposited by the 15th of the following month. For example, contributions for June 2026 are due by 15 July 2026.

Penalties under Section 85 of the ESI Act:

• Simple interest at 12% per annum on the outstanding amount for each day of delay
• Damages levied in addition to interest, based on the delay period:

Example: A CA firm handling a client with an ESI liability of ₹75,000 delayed by 3 months faces:

• Interest: ₹75,000 × 12% × 3/12 = ₹2,250
• Damages: ₹75,000 × 10% = ₹7,500
• Total penalty exposure: ₹9,750 — entirely avoidable with timely filing.

Common Mistakes CA Firms Must Avoid

1. 1Wrong wage base: Reimbursements such as medical, conveyance, or uniform allowances should not be included in the ESI wage base. Verify eligible wage heads against Schedule II of the ESI Act each payroll cycle.
2. 2Missing new joiners: Register each new employee on the ESIC portal within 10 days of joining and issue a temporary ESI identity card immediately to preserve their benefit eligibility.
3. 3Ignoring the wage ceiling rule: Employees who cross ₹21,000/month mid-period remain covered for the full contribution period — contributions must continue until the period ends, not from the month of crossing.
4. 4Last-minute portal filing: The ESIC portal experiences heavy traffic near the 15th deadline. File by the 10th of each month to avoid technical failures that lead to inadvertent late payment.
5. 5Aadhaar not linked: ESIC mandates Aadhaar seeding for all insured persons. Employees without Aadhaar linkage may be denied benefits during the claims process — flag this to your clients and resolve it proactively.
