ESI Registration (ESIC) for Employers in India
ESI registration enrols an establishment with the Employees’ State Insurance Corporation under the Employees’ State Insurance Act, 1948. Unlike provident fund, ESI is health and income-protection insurance rather than savings: it funds medical treatment for the worker and their family, cash during certified sickness and maternity, and compensation for employment injury and death.
The trigger is lower than PF and arrives earlier for a growing business. Non-seasonal factories are covered at 10 or more persons, and most state governments have extended coverage to shops, hotels, restaurants, cinemas, transport undertakings, newspaper establishments, and private educational and medical institutions at the same count. Tamil Nadu, Karnataka, and Telangana all apply the 10-person threshold. Registration is due within 15 days of the Act becoming applicable — not 30.
This guide covers the headcount trigger and where 20 still applies, the wage ceiling and what counts as wages, the 3.25% and 0.75% split, contribution and benefit periods, the benefit schedule, the portal process, the monthly cycle, penalties, and how the Code on Social Security is changing the geography of coverage.

What is ESI registration?
ESI registration allots an establishment a unique employer code with ESIC, through which contributions for all covered employees are paid. Each covered employee receives an insurance number and an e-Pehchan card, which is what gives them and their dependants access to ESIC dispensaries, hospitals, and tie-up facilities.
It is a contributory insurance scheme, not a fund the employee can withdraw. The employer and employee both contribute monthly, and the employee draws benefits in kind — medical care — and in cash when a contingency occurs. Nothing accumulates in a personal balance the way a provident fund does.
Because the scheme delivers treatment through physical facilities, coverage has historically depended on whether the district was notified under the Act. That geographic limitation is being removed as the Code on Social Security is implemented, which is bringing establishments in some smaller cities and districts into coverage for the first time.
When does ESI registration become mandatory?
The Act applies to non-seasonal factories employing 10 or more persons. Beyond factories, coverage is extended by notification of the appropriate government to specified classes of establishment, and the threshold depends on whose notification applies.
| Establishment type | Appropriate government | Threshold (indicative) |
|---|---|---|
| Non-seasonal factory | Central, under the Act | 10 or more persons |
| Shops and commercial establishments | State notification | 10 or more in most states, including Tamil Nadu, Karnataka, Telangana |
| Hotels, restaurants, cinemas, preview theatres | State notification | 10 or more in most states |
| Road motor transport, newspaper establishments | State notification | 10 or more in most states |
| Private educational and medical institutions | State notification | 10 or more in most states |
| Shops, hotels, NBFCs, insurance, ports, airports, warehousing under central control | Central notification | 20 or more persons |
| States that have not reduced the threshold | State notification | 20 or more persons |
The great majority of states and union territories have reduced the establishment threshold from 20 to 10. A few have not, and establishments under central government control in specified categories are covered at 20. The safe practice is to read the notification in force for the state where the unit operates, because this is one of the few thresholds in Indian labour law that genuinely varies.
The count is of persons employed, including part-time, contract, casual, and temporary workers, and is generally tested on any single day in the preceding period rather than as a monthly average. Once the count is reached, the employer has 15 days to register.
Which employees are covered under ESI?
Coverage follows gross monthly wages, not basic pay. Employees drawing gross wages within the prescribed ceiling — long set at ₹21,000 a month, and ₹25,000 for a person with a disability — are covered. An employee drawing above the ceiling at the time of joining is excluded.
- Employees with gross monthly wages within the ceiling — covered
- Employees with a disability, covered up to the higher ceiling
- Part-time, temporary, casual, and probationary employees within the wage limit
- Contract workers engaged in the establishment’s work — the principal employer must ensure compliance
- Employees whose wages cross the ceiling mid-period — contribution continues to the end of the contribution period
- Employees above the ceiling at joining — excluded from coverage
- Apprentices under a statutory apprenticeship scheme — generally outside coverage
The ₹21,000 ceiling has been in force since January 2017 and no revision had been notified as of 2026, though it is periodically discussed. The mid-period rule is the one payroll teams most often mishandle: a mid-year increment that takes someone past ₹21,000 does not end their coverage immediately — contributions continue on the higher wages until the current contribution period closes.
How is the ESI contribution split?
| Contributor | Rate (indicative) | Base | Notes |
|---|---|---|---|
| Employee | 0.75% | Gross wages | Deducted from salary; employees below a prescribed daily wage are exempt from their share |
| Employer | 3.25% | Gross wages | Employer’s own cost, over and above salary |
| Total | 4.00% | Gross wages | Deposited together in one monthly challan |
These rates were reduced to the current level in 2019 and are prescribed by rule, so they can change; confirm the position before finalising payroll. Note the contrast with PF: ESI is computed on gross wages, which makes the base wider, but the combined 4% makes the amount far smaller than PF’s 12% plus 12% on basic wages.
Employees earning below the daily average wage that the rules prescribe are exempt from paying their own share, while the employer still pays its 3.25% for them. That exemption is easy to miss and produces an over-deduction from the lowest-paid staff.
What are contribution periods and benefit periods?
ESI runs on two six-month contribution periods — April to September and October to March — each linked to a corresponding benefit period that follows it. Entitlement to cash benefits is tested against contributions made in the relevant contribution period, which is why the calendar matters more here than in PF.
- 1.Contribution period April to September, with its benefit period beginning the following January
- 2.Contribution period October to March, with its benefit period beginning the following July
- 3.Sickness benefit generally requires contributions for 78 days in a contribution period
- 4.Maternity benefit generally requires contributions for 70 days across the two preceding contribution periods
- 5.Employment injury benefits apply from day one of insurable employment, with no contribution condition
- 6.Wage ceiling changes take effect at the boundary of a contribution period for existing members
The practical consequence is that a late or missed month does not only cost interest — it can cost an employee their entitlement by pulling their contribution days below the qualifying number. That is a materially different consequence from a late PF remittance.
What benefits does ESI provide to employees?
| Benefit | Indicative rate | Broad condition |
|---|---|---|
| Medical benefit | Full medical care for the insured person and dependants | From entry into insurable employment |
| Sickness benefit | About 70% of wages, up to roughly 91 days a year | Around 78 days of contribution in a contribution period |
| Maternity benefit | Full wages for 26 weeks, extendable on medical advice | Around 70 days of contribution in the two preceding periods |
| Temporary disablement benefit | About 90% of wages while disability lasts | Employment injury, from day one |
| Permanent disablement benefit | About 90% of wages as a monthly payment | Assessed loss of earning capacity |
| Dependants’ benefit | About 90% of wages, monthly, to dependants | Death due to employment injury |
| Funeral expenses | Up to about ₹15,000 | From day one of insurable employment |
| Unemployment relief (ABVKY) | About 50% of average daily wages, up to 90 days, once in a lifetime | Involuntary unemployment, with prescribed contribution history |
These rates and amounts are prescribed and periodically revised by ESIC, so treat the figures as indicative. The unemployment relief scheme in particular is extended year by year — the current extension runs to 30 June 2027 — and should never be described to employees as permanent.
For a low-wage workforce this is the most valuable statutory benefit an employer provides, because medical cover extends to the family and employment-injury benefits apply from the first day without any contribution condition.
How is ESI registration different from PF registration?
They are separate registrations with separate authorities, and an employer past both thresholds holds both. ESI arrives first for most growing businesses, at 10 employees in most states against PF’s 20, and its registration deadline is tighter at 15 days rather than about 30.
The economics differ too. ESI is computed on gross wages at a combined 4%, so it is cheap but applies to a wide base; PF registration is computed on basic wages plus dearness allowance at 12% from each side, so it is expensive but applies to a narrower base. ESI coverage stops for a new joiner above ₹21,000 gross; PF coverage stops for a new joiner above ₹15,000 basic plus DA — different numbers, different bases, and both tested at joining.
The one thing they share is the deadline. Both the ESI contribution and the PF challan are due by the 15th of the following month, which makes that date the single most important entry in an employer’s payroll calendar.
What documents are required for ESI registration?
- PAN of the establishment and of the employer
- Certificate of incorporation, LLP agreement, partnership deed, or registration certificate
- Shop & Establishment or factory registration certificate for the premises
- GST registration certificate
- Proof of the establishment address — rent agreement, sale deed, or utility bill
- Licence issued under the Factories Act or Shops Act, where applicable
- A cancelled cheque of the establishment’s bank account
- List of directors, partners, or the proprietor with identity details
- List of all employees with date of joining, gross monthly wages, and Aadhaar
- Employee family details and nominee details for insurance records
- Date on which the employee count first reached the applicable threshold
- Digital Signature Certificate of the authorised signatory, where the portal requires signing
The wage list is the document that decides your liability, so it needs to state gross wages rather than basic pay. Establishments that submit a basic-pay list end up under-contributing and have the shortfall demanded with interest later.
How to register for ESI online?
- 1.Create an employer account on the ESIC portal or on the Shram Suvidha portal
- 2.Confirm the login credentials sent to the registered email
- 3.Open the employer registration form and select the establishment category
- 4.Enter establishment name, address, PAN, GSTIN, constitution, and date of commencement
- 5.Declare the date on which the employee count reached the applicable threshold
- 6.Enter the number of employees and the number within the wage ceiling
- 7.Add each covered employee with wages, Aadhaar, bank and family details
- 8.Enter the establishment’s bank details
- 9.Upload the entity, premises, and licence documents
- 10.Submit the form, digitally signing where required
- 11.Receive the employer code number and download the registration letter
- 12.Generate insurance numbers and issue e-Pehchan cards to employees
The Shram Suvidha route allows a common registration covering ESI alongside EPF and other labour registrations, which is worth using when both thresholds are crossed close together. Registration itself is generally processed quickly; the slower part is collecting complete employee and family data.
What are the monthly ESI compliances after registration?
- 1.Compute gross wages for each covered employee for the month
- 2.Deduct the employee’s 0.75% share, applying the low-wage exemption where relevant
- 3.Add the employer’s 3.25% share
- 4.Generate the monthly contribution challan on the ESIC portal
- 5.Deposit both shares by the 15th of the following month
- 6.Register every new joiner within the ceiling promptly and issue the insurance number
- 7.Mark exits on the portal so records and entitlements stay accurate
- 8.Maintain the register of employees, the wage register, the accident register, and the inspection book
- 9.Track employees whose wages cross the ceiling and stop contributions at the correct period boundary
- 10.Report accidents in the prescribed manner, since injury benefits apply from day one
ESIC’s move to monthly online contribution filing has largely subsumed what used to be periodic returns, though some guidance still refers to half-yearly return forms. Confirm what your establishment is expected to file rather than assuming either position — ongoing filing is covered under ESI return filing.
How much does ESI registration cost?
ESIC charges no registration fee. The cost is the recurring 3.25% employer contribution on the gross wages of covered employees, which for a low-wage workforce is a small and predictable line.
| Item | Charged by | Indicative position |
|---|---|---|
| ESI registration / employer code | ESIC | Nil |
| Employer contribution | Statutory | 3.25% of gross wages of covered employees |
| Employee contribution | Statutory | 0.75% of gross wages, deducted from salary |
| Interest on delayed payment | Statutory | A prescribed annual rate on the unpaid amount |
| Damages on default | Statutory | A percentage of arrears, escalating with the length of delay |
| Digital Signature Certificate | Certifying Authority | Per signatory, where portal signing is required |
| Professional fees | CA firm | Scoped after a short discovery call |
Contribution rates are prescribed by rule and have been revised before, so these are indicative and confirmed before payroll setup. The comparison worth making internally is against the cost of private group medical cover for the same workforce, which is usually higher for equivalent family coverage.
What are the penalties for ESI non-compliance?
Late payment attracts simple interest on the delayed contribution, commonly at 12% a year, and damages at rates that escalate with the length of the default. Both can be levied, and the damages are separate from the interest.
The Act also provides for prosecution. Deducting the employee’s share and failing to deposit it is treated as the aggravated case, with imprisonment and fine provided for, because the money withheld was never the employer’s. Failure to register at all can result in a demand from the date the Act applied, with interest and damages layered on.
There is a further cost that does not show on a challan. If contribution days fall below the qualifying number, an employee can lose sickness or maternity entitlement — and an employer who caused that by late remittance can find itself meeting the claim commercially. ESIC has periodically run amnesty-style schemes allowing employers to register and declare past employees without the usual consequences, but they are time-bound and should not be assumed to be open.
How does the Code on Social Security change ESI?
The four labour codes came into force on 21 November 2025 and the Social Security (Central) Rules were notified on 8 May 2026. For ESI the most significant structural change is geographic: the Code extends coverage nationwide rather than limiting it to districts notified under the old Act, which brings establishments in previously unnotified areas into the scheme.
The Rules also operationalise a tighter exemption framework — requiring majority employee consent and self-certified proof of compliance and remittances — and generally prevent a covered establishment from seeking inapplicability before a period of years from the date coverage began. Exempted establishments remain subject to continuing conditions and record-keeping.
State rules under the codes are still being notified, and the timing of nationwide ESI applicability depends on the applicable central or state rules for each establishment. If your unit sits in a district that was previously outside a notified area, treat coverage as a question to confirm for your location rather than a settled answer either way.
What are the common mistakes in ESI compliance?
- Applying PF’s 20-employee threshold to ESI, which bites at 10 in most states
- Assuming 30 days to register when the ESI window is 15 days
- Computing contributions on basic pay instead of gross wages
- Stopping contributions mid-period when an employee’s wages cross the ceiling
- Over-deducting from the lowest-paid staff who are exempt from the employee share
- Excluding part-time, casual, and contract workers from the headcount and from coverage
- Not verifying that a labour contractor is actually remitting for supplied workers
- Failing to register new joiners promptly, so they have no insurance number when they need care
- Not maintaining the accident register, which matters because injury benefits start on day one
- Assuming a district is outside coverage without checking the current notification position
