Expert verified | TL;DR Summary ESI applicability starts when you have 10 or more employees. The monthly gross wage ceiling is ₹21,000 for coverage. The employer pays 3.25%, employee pays 0.75% of wages. Register within 15 days of becoming applicable. Pay contributions by the 15th of next month. Late payment triggers 12% annual interest plus damages up to 25%. Deducting ESI from salaries and not depositing it can lead to 1 year jail and ₹10,000 fine. Contract, part-time, and temporary workers are covered. Gig workers are not yet covered under current law. Use SPREE 2025 to register voluntarily without past penalties before 31 December 2025. |
ESI registration is mandatory in India for any establishment employing 10 or more persons (including part-time, contract, and temporary workers) on any single day in the preceding 12 months, covering all employees earning a monthly gross wage of ₹21,000 or less (₹25,000 for employees with disabilities) — employer contribution is 3.25% and employee contribution is 0.75% of gross wages, deposited by the 15th of the following month, with registration required within 15 days of crossing the threshold.
Late payment attracts 12% annual interest plus damages up to 25% of arrears; deducting ESI from employee salaries without depositing it carries a minimum one-year jail term and ₹10,000 fine, and once registered, an establishment remains covered even if headcount later drops below 10.
ESI applicability is a frequent compliance trigger in India. Once your business crosses the employee threshold, it is a legal trigger with real consequences if you ignore it.
In this blog, we walk you through the wage ceiling, contribution rates, and exactly which workers must be covered.
You will also learn how to register on the ESIC portal, avoid penalties for late payment, and understand benefits your employees are entitled to.
What Is ESI and Why Does It Matter in Compliance Audits?
Employees’ State Insurance (ESI) is a social security programme for workers in India. It’s governed by the ESI Act, 1948, and managed by the Employees’ State Insurance Corporation (ESIC).
The scheme provides covered employees with medical care, sickness cash benefits, maternity support, disability compensation, and dependent benefits. Both the employer and employee contribute to this fund monthly.
For an employer, ESI is a mandatory legal requirement that directly impacts compliance audits. Here’s why it’s critical:
Rules are specific and enforceable: ESIC officers can inspect premises, examine payroll records, raise demands for arrears, and initiate criminal prosecution.
In an audit, inspectors check whether your establishment was registered on time, whether all eligible employees are enrolled, whether contributions are deposited by the 15th, and whether half-yearly returns are filed within the deadline.
Mistakes in ESI compliance are expensive: If an audit finds that you missed the registration deadline, didn’t deduct the correct employee share, or paid contributions late, the financial penalties add up quickly.
The ESIC will recover all dues, plus interest and damages from the very date the payment was due, not from when you correct the error.
Compliance with ESI is often a prerequisite for other business activities: Government departments and large corporate clients routinely ask for an ESIC compliance certificate to qualify for contracts or tenders.
A single default can disqualify you from lucrative opportunities.
Therefore, proactively managing your ESI registration, timely payments, and accurate reporting is not just about avoiding penalties.
It’s about ensuring your business is audit-ready at all times, protecting your employees’ benefits, and maintaining a clean compliance record that builds trust with clients and authorities.
ESI Applicability: Which Businesses Must Register?
ESI applicability is determined by two main factors:
- Type of establishment
- Number of employees.
The ESI Act applies to any establishment that employs 10 or more persons on any single day during the preceding 12 months.
This includes all kinds of commercial establishments like shops, hotels, restaurants, cinemas, road transport undertakings, newspaper establishments, and even private educational and medical institutions, as notified by state governments
Some states still apply a threshold of 20 employees for certain categories of commercial establishments. Check with your state’s Labour Department if you are unsure which limit applies to your business type.
What counts toward the threshold?
| Worker Category | Counted? |
| Permanent employees | Yes |
| Part-time workers | Yes |
| Temporary staff | Yes |
| Probationers | Yes |
| Contract / outsourced staff on your premises | Yes |
The 10-employee count includes all categories of workers: permanent, temporary, part-time, contract, and probationary staff. Contract workers deployed at your premises through a third-party contractor also count toward this threshold.
Once covered, always covered
A critical point often missed is the “once covered, always covered” rule. Once your establishment crosses the threshold and comes under the ESI Act, you remain covered even if your employee count later drops below 10.
The ESI Act does not allow exit from the scheme simply because employee numbers reduce after registration.
Registration deadline
If your business falls under the ESI Act, you must register immediately. You have only 15 days from the day you first employ 10 persons to complete the registration on the ESIC portal.
Operating beyond this 15-day window without registration is a violation.
Industry type does not determine applicability. ESI applies to all establishments including IT companies, software firms, BPOs, and startups, in states where the Act is notified. Only the employee count and wage ceiling matter.
The ₹21,000 Wage Ceiling — Who Is Covered?
Even if your business qualifies for ESI registration, not every employee is automatically covered. The second major filter is the employee’s wage ceiling.
The law currently states that only employees drawing a monthly gross wage of up to ₹21,000 are mandatorily covered under the scheme.
A very important exception is for employees with disabilities. For them, the wage ceiling is higher. If a person with a disability is employed in your covered establishment, they are eligible for ESI coverage up to a monthly wage of ₹25,000.
Note: No state can set a different ESI wage ceiling. This is a central government notification applicable uniformly across India.
What counts as “wages” for ESI purposes?
For ESI purposes, “wages” is not just the basic salary. It is the total of all remuneration paid in cash, including:
- Basic pay
- Dearness Allowance (DA)
- House Rent Allowance (HRA)
- City Compensatory Allowance
- Overtime wages
- Any other regular allowances.
Under the Labour Codes implemented in November 2025, a uniform definition of “wages” applies: Basic + DA + retaining allowance must be at least 50% of total remuneration (CTC), and excluded components (HRA, conveyance, overtime, bonuses, etc.) cannot exceed 50%.
Companies that previously kept basic pay low to avoid ESIC coverage will no longer be able to do so. ESIC wages are now calculated on Basic + DA, not gross salary.
For an employee with CTC ₹30,000 and basic ₹12,500, the new rule forces basic up to at least ₹15,000 (50% of CTC), so ESI wages become higher, not lower.
If ESI wages are ≤ ₹21,000, the employee is mandatorily covered; if they were previously exempt because artificial salary structuring kept ESI wages below the threshold, the new rule may bring them into ESI coverage.
Mid-year salary increments
If an employee’s salary crosses ₹21,000 mid-way through a contribution period, their ESIC coverage does not end immediately. If wages exceed ₹21,000 mid-contribution period, April to September or October to March, coverage continues until the end of that period. From the next contribution period, if the wages remain above ₹21,000, they exit the scheme.
Employees earning daily average wages up to ₹176 are exempt from their own contribution share, but the employer still contributes 3.25% on their behalf.
Contribution Rates: Employer 3.25%, Employee 0.75%
The ESI scheme is financed through contributions from both you and your employees.
Since July 1, 2019, the rates are fixed at a total of 4% of the employee’s gross wages. Here is exactly how it breaks down:
| Contributor | Rate |
| Employer | 3.25% of gross wages |
| Employee | 0.75% of gross wages |
| Total | 4% of gross wages |
The employer deducts the employee’s 0.75% from their salary and remits both portions together to ESIC.
Exception for persons with disabilities
For establishments employing persons with disabilities, the employer contribution rate reduces to 1% as an incentive. The employee contribution of 0.75% remains the same.
Contribution due date
Monthly ESI contributions must be deposited by the 15th of the following month. Contributions for wages paid in January, for instance, must reach ESIC by 15 February.
Half-yearly return deadlines
| Contribution Period | Return Filing Deadline |
| 1 April – 30 September | 11 November |
| 1 October – 31 March | 11 May |
Employers have 42 days from the end of each contribution period to file returns.
Contributions are calculated on the gross wages of each covered employee, not just basic pay. Calculating on a lower wage base creates a shortfall that ESIC can treat as arrears, with interest.
Are Contract, Gig and Part-Time Workers Covered?
Yes, with some important clarifications. The law is shifting to include new workforce structures.
Here is the breakdown of coverage under both the current ESI Act and the new Social Security Code.
Contract workers
Yes. The 10-employee count includes contract workers deployed at your premises through a third-party contractor.
If those workers earn ₹21,000 or less per month, they must be registered under ESIC. The principal employer carries secondary liability if the contractor fails to provide this coverage.
So, if you outsource a contract security guard working at your factory gate, that guard must be covered under your ESI if their wages are within the ceiling, regardless of who pays their salary.
This is a frequent gap in HR audits. A business with 7 direct employees and 4 contract security or housekeeping staff has already crossed the ESIC threshold and is liable for coverage of all eligible contract staff, whether or not the staffing agency has fulfilled its own obligations.
Part-time workers
Part-time workers are also treated exactly the same as full-time employees. The law counts heads, not hours. There is no minimum hours requirement.
If they earn ₹21,000 or less per month and your establishment meets the headcount threshold, they must be covered.
Gig and platform workers
This is where the old law is changing. The Code on Social Security, 2020 formally recognizes “gig workers” and “platform workers” for the first time in Indian labour history.
In the future, aggregators like Ola, Swiggy, Zomato, etc., may need to contribute 1-2% of their annual turnover to a Social Security Fund for these workers.
However, the Code’s rules are still being finalized.
The current practical position is that gig workers are not automatically covered under the ESI Act if they are not on your payroll. But as an employer, you must plan for the future. When the new rules are fully implemented, your compliance framework will need to expand to include these workers.
Step-by-Step: How to Register on the ESIC Portal
Registration is done and the process is completely paperless. You must complete it within 15 days of crossing the 10-employee threshold.
Step 1: Sign up as an employer
Go to esic.gov.in and click on “Employer Registration” under the Sign Up section. Enter your establishment name, address, nature of business, and contact details.
Step 2: Verify your email and mobile number
After submitting the sign-up form, you will receive a confirmation email to your registered email ID and mobile number. Complete verification to activate your account.
Step 3: Fill Form 01 (Employer Registration Form)
Access the ESIC portal through the “Employer Login” on the home screen, click on “New Employer Registration,” choose the type of unit from the dropdown, and fill in the Employer Registration Form 01. This includes unit details, employer details, factory or establishment information, and employee details.
The form captures: nature of business, date of commencement, total employee count, principal employer details, and bank information.
Step 4: Pay the advance contribution
Following submission of Form 01, a prompt appears for payment of advance contribution. This is a one-time deposit as part of registration.
Step 5: Receive your 17-digit ESIC code
Once payment is confirmed, you receive a permanent 17-digit ESIC registration number used for all future filings, returns, and employee registrations.
Step 6: Register each eligible employee
Within 10 days of an employee joining, register them on the ESIC portal. You need their Aadhaar number, date of birth, wage details, and nominee information.
Each employee receives an Insurance Number and a Pehchan Card for accessing ESIC hospitals and dispensaries.
ESI Benefits Employees Are Entitled To
ESI is a comprehensive social security shield. Once your business registers and starts paying contributions, your eligible employees unlock a range of benefits under the scheme:
Medical benefit
Full medical care (primary, secondary, and tertiary) for both the employee and their family members, from day one of insurable employment.
Where ESIC hospitals are not available, access is provided through empanelled private facilities. Retired and permanently disabled insured persons can also continue accessing medical care on payment of a token annual premium of ₹120.
Sickness benefit
Cash compensation at 70% of wages for certified sick leave, for a maximum of 91 days in a year. To qualify, the employee must have contributed for at least 78 days in the preceding six-month contribution period.
For 34 specified long-term and malignant diseases, this extends up to two years at 80% of wages.
Maternity benefit
Maternity benefit is payable for 26 weeks at 100% of wages, subject to contribution for 70 days in the preceding two contribution periods.
Women with two or more surviving children receive 12 weeks.
Disablement benefit
- Temporary: 90% of wages, payable from day one of insurable employment, irrespective of contributions made — in the case of employment injury.
- Permanent: 90% of wages as a monthly payment, determined by the extent of loss of earning capacity as certified by a Medical Board.
Dependent benefit
Paid at the rate of 90% of wages as a monthly payment to dependants of a deceased insured person, where death occurs due to employment injury or occupational hazard.
Funeral expenses
₹15,000 is payable to the dependants or the person performing the last rites, from day one of insurable employment.
Unemployment allowance
Financial relief is available for up to 24 months in case of involuntary unemployment, subject to eligibility conditions including a minimum of two years in insurable employment and contributions for at least 78 days in specified periods.
Physical aids & rehabilitation
Free supply of aids and vocational training. Crutches, wheelchairs, dentures, spectacles, and other physical aids provided free.
Vocational rehabilitation available for disabled persons under 45 years with 40% or more disablement
Two important points: First, retired employees and their spouses can continue medical coverage by paying just ₹120 annually, provided they completed five years of insurable employment before retirement.
Second, ESIC operates over 150 hospitals and nearly 1,450 dispensaries across India, ensuring wide access to these benefits.
Penalties for Non-Registration or Late Payment
Non-compliance with ESIC is an offence. The consequences fall into three categories: financial penalties, interest, and criminal prosecution.
Late payment interest and damages
Missing the 15th of the month deadline triggers 12% annual interest on delayed contributions, calculated daily. The ESIC can recover arrears as land revenue.
Under Section 85-B, the Corporation may recover damages from the employer by way of penalty if any employer fails to pay contributions within the specified time limit or pays them belatedly.
The damages are calculated as a percentage of the contribution amount:
| Delay Period | Damages Rate (as % of contribution amount) |
| Up to 2 months | 5% |
| 2 to 4 months | 10% |
| 4 to 6 months | 15% |
| 6 months and above | 25% |
Note: that damages are levied in addition to interest. Paying the contribution and interest does not absolve you from paying damages.
The ESIC authorities can initiate proceedings to recover damages years after the default. There is no limitation period under the Act.
Criminal prosecution under Section 85
For failure to pay the employee’s contribution that has been deducted from wages, imprisonment must not be less than one year and a fine of ₹10,000 applies.
For other defaults, imprisonment must not be less than six months with a fine of ₹5,000, extendable to three years’ imprisonment.
Non-payment of contributions is an economic offence, and the Legislature has fixed both a minimum term of imprisonment and a fixed amount of fine.
Under Section 85-A, a second conviction for non-payment can attract imprisonment of up to five years.
As a business, make sure to set up automated payroll reminders to ensure contributions are deposited by the 12th or 13th of each month, not the 15th.
And if you have already missed registration, use the SPREE 2025 scheme to register voluntarily before December 31, 2025, and avoid past penalties.

FAQs
Q1: What is the ESI applicability threshold for 2026?
ESI registration is mandatory for establishments that employ 10 or more persons on any day of the preceding 12 months. Some states maintain a 20-employee threshold for certain establishment types. The count includes permanent, part-time, temporary, contractual, and probationary staff. Registration must be completed within 15 days of crossing the threshold.
Q2: Are gig and contractual staff covered under ESI?
Contract workers on your premises count toward the 10-employee threshold and must be covered under ESIC if they earn ₹21,000 or less. Gig and platform workers fall within the social security framework for the first time under the Code on Social Security, 2020, but through a separate fund mechanism, not direct ESI membership, with specifics still being notified state by state.
Q3: What is the ESI contribution rate for employers in 2026?
The employer contribution rate is 3.25% of wages and the employee rate is 0.75%, making the total 4%. These rates have been in force since July 2019 and remain unchanged in 2026. The employer deducts and remits both shares to ESIC by the 15th of the following month.
Q4: What is the wage limit for ESI coverage?
The current ESI wage ceiling is ₹21,000 per month in gross wages for regular employees and ₹25,000 for employees with disabilities. This ceiling has applied since January 2017. As of April 2026, no revision has been notified.
Q5: How do I register on the ESIC portal?
Visit esic.gov.in, sign up under “Employer Registration,” verify your email and mobile, and fill Form 01 with your establishment details. Pay the advance contribution, and you receive a 17-digit ESIC registration code. Each eligible employee must then be registered on the ESIC portal within 10 days of joining.
Q6: What is the penalty for ESI non-compliance?
Late contributions attract 12% annual interest and damages up to the full arrear amount under Section 85-B. Non-payment is a criminal offence under Section 85, carrying a minimum six months’ imprisonment and fine of ₹5,000, extendable to three years. Deducting employees’ ESI share and not depositing it carries a minimum one-year sentence and ₹10,000 fine.
Q7: If an employee’s salary crosses ₹21,000 mid-year, do they lose ESI?
Not immediately. If wages exceed ₹21,000 during the mid-contribution period April to September or October to March, coverage continues until the end of that period. The employee exits the scheme from the start of the next contribution period, provided their wages stay above the ceiling.
