Under Section 2(12) of the ESI Act, 1948, factories and other establishments employing 10 or more persons (20 in some states) in areas notified by the Central Government must register with the Employees' State Insurance Corporation (ESIC). Register online at esic.gov.in within 15 days of reaching the threshold.

Employees earning gross wages up to INR 21,000 per month (INR 25,000 for persons with disability) are mandatorily covered. Obtain the ESIC Insurance Number (IP Number) for each insured person through the employer portal.

ESI operates on a six-month contribution period: April to September and October to March. The corresponding benefit periods are January to June and July to December respectively. Ensure coverage and eligibility are assessed per this cycle.

If the organization operates multiple branches in different ESIC regions, each unit must obtain a separate ESIC code. The principal employer must ensure all contract laborers at each site are also enrolled.

ESIC has mandated Aadhaar linking for all insured persons to facilitate biometric verification at ESI dispensaries and hospitals. Complete Aadhaar seeding through the employer portal to avoid disruption in benefit disbursement.

The employee's share of ESI contribution is 0.75% of gross wages (inclusive of basic, DA, HRA, overtime, and all other allowances except washing allowance). Deduct this amount from the employee's monthly salary before disbursement.

The employer's contribution is 3.25% of the gross wages of insured employees. This amount is borne entirely by the employer and is not deductible from employee wages. The total contribution rate is 4% (employer 3.25% + employee 0.75%).

Contributions for each month must be deposited on or before the 15th of the following month through the ESIC online payment portal. Generate the challan, verify employee-wise details, and make payment via net banking.

Under Section 85 of the ESI Act, delayed contributions attract simple interest at 12% per annum. Additionally, damages up to 25% of the arrears can be levied under Section 85B. Persistent default may result in prosecution under Section 85(a)-(g).

If an employee's wages exceed INR 21,000 during a contribution period due to a raise, they remain covered until the end of that six-month contribution period. De-register them only at the start of the next contribution period if wages still exceed the ceiling.

Under Rule 32 of the ESI (General) Regulations, 1950, maintain a register of attendance of insured persons in Form 6. Record daily attendance, leave, and absence details to support any benefit claims by employees.

Submit the Return of Contributions in Form 5 (now filed online) within 42 days of the end of each contribution period. The return must contain employee-wise wage and contribution data for the six-month period.

Record details of every employment injury (accident, occupational disease) in the Accident Book. Report accidents to the nearest ESIC Branch Office and the local ESI dispensary within 24 hours to enable the employee's claim for disablement benefit.

Maintain all wage registers, contribution challans, Form 5 returns, and employee records for at least 5 years from the end of the relevant contribution period. These records may be requisitioned during inspections under Section 45.

Insured employees are entitled to medical benefits (treatment at ESI dispensaries/hospitals), sickness benefit (70% of wages for up to 91 days), maternity benefit (full wages for 26 weeks), and disablement benefit. Provide employees with their IP number and nearest ESI dispensary details.

Help employees submit claim forms: Form 12 for sickness benefit, Form 19/20 for maternity benefit, and Form 14 for temporary disablement benefit. Certify the employee's wage and attendance details on the form before submission to the ESIC Branch Office.

If an insured employee dies due to an employment injury, the dependents are entitled to a pension under Section 52. Assist the family in filing Form 16 and provide the required wage certificate and employment details.

When an employee leaves, issue Form 105 showing the contributions paid during the current contribution period. This enables the employee to claim continuation of benefits or portability to their new employer's ESIC coverage.

Under Section 45 of the ESI Act, SSOs have the right to enter and inspect any premises covered under the Act. Keep all registers, wage records, and contribution challans organised and readily available for examination.

Download the employer-wise and employee-wise contribution details from the ESIC portal and reconcile them with internal payroll data every quarter. Address discrepancies proactively before they are flagged in an audit.

If an assessment order is issued under Section 45A for short or non-payment, respond within the timeline specified (usually 15 days). Provide wage registers, bank statements, and ECR challan copies to substantiate your payment records.

For contested assessments, appeals under Section 75, or disputes over coverage, engage a consultant or advocate experienced in ESI law. Appeals can be filed with the Employees' Insurance Court under Section 74 within the prescribed limitation period.
