What is ESI and which companies must register?
The Employees’ State Insurance (ESI) scheme, administered by the Employees’ State Insurance Corporation (ESIC), is India’s primary social security programme for industrial and commercial workers. It provides comprehensive medical care, sickness benefits, maternity benefits, disability compensation, and dependent benefits to insured employees and their families. ESI is governed by the Employees’ State Insurance Act, 1948, and applies to establishments employing 10 or more persons (20 or more in some states under the old framework, though the new Social Security Code standardises this at 10 across all establishments). The coverage applies to non-seasonal factories using power, shops, hotels, restaurants, cinemas, road transport establishments, newspaper establishments, and educational and medical institutions, among others. Under the new labour codes, ESI coverage is being expanded to all sectors, and the threshold may be reduced further to cover smaller establishments.
The key threshold for employee coverage is the wage ceiling. Employees earning gross wages up to ₹21,000 per month (₹25,000 for persons with disabilities) are covered under ESI. If an employee’s gross wages exceed this ceiling, they are not covered, even if the establishment is registered under ESI. Crucially, once covered, an employee continues to be covered for the entire contribution period (April-September or October-March) even if their wages cross the ceiling mid-period. The wage definition for ESI purposes includes basic pay, dearness allowance, house rent allowance, city compensatory allowance, overtime wages, and all other allowances except certain specified exclusions. This broad definition means that many employees whose basic salary appears below the threshold may actually be covered because their total gross earnings exceed ₹21,000 per month. Companies must register under ESI within 15 days of the Act becoming applicable to them (i.e., within 15 days of employing the 10th employee).
ESI contribution rates and calculation
ESI contributions have been significantly reduced in recent years to ease the burden on both employers and employees. The current rates (effective from July 2019) are: employer contribution at 3.25% of wages, and employee contribution at 0.75% of wages, for a total contribution of 4% of wages. This was a substantial reduction from the earlier rate of 4.75% (employer) + 1.75% (employee) = 6.5% total. The reduced rates have made ESI compliance more affordable, especially for small and medium enterprises. Contributions are calculated on the actual gross wages paid, not on a ceiling or fixed amount. For example, an employee earning ₹18,000 per month would have an employer contribution of ₹585 (3.25%) and an employee contribution of ₹135 (0.75%), totalling ₹720 per month.
Contributions must be deposited with ESIC by the 15th of the month following the salary month. For example, contributions for January salaries must be deposited by 15th February. Late payment attracts interest at 12% per annum from the due date until the date of actual payment. Penalties for non-payment or delayed payment include recovery proceedings (attachment of bank accounts, property, and even arrest warrants in extreme cases of wilful default). The contribution period runs in six-month cycles: April-September (contribution period 1) and October-March (contribution period 2). ESI returns (half-yearly) must be filed within 42 days from the end of each contribution period. The returns include employee-wise details of wages paid and contributions deducted. Workro’s compliance hub includes an ESI calculator that automatically computes contributions based on the gross wage definition, ensuring accuracy and preventing under-contribution.
Online ESI registration process
ESI registration is now entirely online through the ESIC portal. The process begins at www.esic.in under the “Employer Login” section. Step 1: Click on “Sign Up” and fill in the establishment details — name, postal address, factory or establishment licence details (if applicable), PAN, nature of business, constitution (proprietorship, partnership, private limited, etc.), and contact information. Step 2: Upload the required documents — Certificate of Incorporation or Registration, Memorandum and Articles of Association (for companies), Partnership Deed (for partnerships), PAN card of the establishment, cancelled cheque or bank statement for bank account verification, list of directors or partners with their addresses, rent agreement or ownership proof of the business premises, and the list of employees with their details (name, father’s name, date of birth, date of joining, and monthly wages).
Step 3: Once the application is submitted, ESIC issues a unique 17-digit Employer Code Number. This code is the primary identifier for all ESI transactions and must be quoted in all correspondence with ESIC. Step 4: After registration, the employer must register each covered employee and generate an Insurance Number (IP Number) for them. Employees who have previously been covered under ESI through another employer will already have an IP Number — this number stays with the employee for life, and the new employer links the employee to their code. Step 5: Issue ESI cards (Pehchan cards) to employees — these are used to access medical facilities at ESI hospitals and dispensaries. The ESIC now issues a digital Pehchan card via SMS and email, and physical cards can be downloaded from the portal. The entire registration process typically takes 7-14 working days if all documents are in order.
Benefits provided under ESI
ESI provides a comprehensive package of benefits to insured employees and their dependents. Medical benefit provides full medical care, including hospitalisation, specialist consultation, diagnostic services, and medicines at ESI hospitals and dispensaries — available from day one of employment for the employee and for family members. Sickness benefit provides cash compensation at 70% of wages for up to 91 days during two consecutive contribution periods for certified illness. Extended sickness benefit at 80% of wages is available for specified long-term diseases (TB, leprosy, cancer, mental illness, etc.) for up to two years. Maternity benefit provides 100% of wages for 26 weeks of maternity leave (as per the Maternity Benefit Amendment Act, 2017), extendable by one month on medical advice, plus a medical bonus of ₹3,500 if ESI hospital facilities are not available for delivery.
Disablement benefit provides lifelong compensation for employment-related injuries resulting in permanent disablement (calculated as a percentage of wages based on the degree of disablement), and temporary disablement benefit at 90% of wages during the period of treatment. Dependent benefit provides monthly pension to dependents of an insured employee who dies due to an employment injury — 90% of wages to the spouse (until remarriage) and 40% to each child (until age 25). Funeral expenses of ₹15,000 are payable on the death of an insured employee. Additionally, the Rajiv Gandhi Shramik Kalyan Yojana (unemployment allowance) provides 50% of wages for up to 24 months to insured employees who lose their jobs due to retrenchment, factory closure, or permanent invalidity. These benefits collectively make ESI one of the most comprehensive social security programmes for the organised workforce, and HR teams should communicate these benefits to covered employees — many employees see ESI deductions as a cost without understanding the value they receive in return.
Common ESI compliance mistakes and how Workro helps
The most frequent ESI compliance errors in Indian companies are entirely avoidable. Under-contribution due to incorrectly excluding allowances from the wage definition — remember that ESI wages include virtually all allowances except a few specific exclusions. Not covering employees whose wages exceed ₹21,000 mid-contribution-period — once covered, employees remain covered for the entire six-month period. Late registration — the 15-day deadline for registration after the Act becomes applicable is strictly enforced, and penalties for delayed registration can be substantial. Failing to register remote employees in the correct state — ESI coverage and benefits are location-specific, and employees should be registered with the ESI office in the state where they are physically located. Incorrect employee details (wrong name, father’s name, or date of birth) that prevent employees from accessing medical benefits — this is a common source of employee grievance.
For companies with distributed workforces across multiple states, managing ESI compliance manually becomes a significant operational burden. Workro’s compliance tools include automated ESI contribution calculations based on the correct wage definition, state-specific registration guidance, and integrated workflows that ensure new hires are registered with ESI if they fall within the wage threshold. The platform’s compliance calendar tracks due dates for contributions and returns, and automated reminders prevent missed deadlines. By centralising compliance management within the same platform used for recruitment, Workro eliminates the data disconnect that occurs when hiring data lives in one system and compliance data in another.
