ESI Act 1948 and Social Security Code 2020: Employer Guide to ESIC Registration, Contributions, Benefits and Compliance in India (2026)

Does your establishment employ 10 or more people? If at least one employee earns Rs 21,000 or less per month, your establishment must register with ESIC within 15 days. Operating without registration means you are denying employees their medical insurance entitlement and exposing yourself to imprisonment of up to 3 years under the Social Security Code. Beyond registration, the law mandates monthly contribution deposits, half-yearly returns, and ongoing compliance with benefit administration.

The Employees' State Insurance Act, 1948 created India's first comprehensive social security system for organised sector workers. It provided medical care, cash benefits during sickness and maternity, compensation for workplace injuries, and survivor benefits for dependants. ESIC (Employees' State Insurance Corporation) administers the scheme through a network of hospitals, dispensaries, and branch offices.

The ESI Act was repealed on 21 November 2025 when the Code on Social Security, 2020 (SS Code) came into force. The SS Code consolidates the ESI Act along with seven other social security laws into a single framework. However, employers still operate under the same contribution rates, wage ceilings, and benefit structures during the transition period (ending 20 November 2026), with targeted improvements in definitions and coverage.

This guide covers the complete ESIC employer compliance framework: registration, contribution calculation, the benefit structure, filing obligations, penalties, and the SS Code 2020 changes that affect your payroll operations in 2026.

What Was the ESI Act 1948?

The Employees' State Insurance Act, 1948 (Act No. 34 of 1948) received Presidential assent on 19 April 1948. It was India's first self-financing social security legislation, designed to protect lower-income workers in the organised sector against the financial impact of sickness, maternity, disability, and death arising from employment.

The Act created the Employees' State Insurance Corporation (ESIC) as an autonomous body under the Ministry of Labour and Employment to:

• Collect contributions from employers and employees
• Operate hospitals and dispensaries for medical care
• Disburse cash benefits (sickness, maternity, disability, dependent)
• Manage a nationwide network of branch offices and regional offices

The ESI Act applied to factories and notified establishments in implemented areas. Coverage expanded progressively from industrial workers in the 1950s to shops, hotels, restaurants, cinemas, newspaper establishments, educational institutions, and medical institutions through state government notifications over decades.

Who Must Register: Coverage Thresholds

Establishment Threshold

ESIC registration is mandatory for:

• Factories employing 10 or more persons
• Other establishments (shops, hotels, restaurants, cinemas, road transport, newspapers, educational and medical institutions) employing 10 or more persons in states that have notified them

A few states (historically Maharashtra and Chandigarh) applied a 20-employee threshold for certain establishment categories, but most states now use the 10-employee standard.

Employee Wage Ceiling

An employee is covered under ESIC only if their gross monthly wages are Rs 21,000 or below (Rs 25,000 for persons with disabilities).

Both thresholds must be satisfied simultaneously: the establishment must have 10+ employees AND at least one employee must earn within the wage ceiling.

Who Counts Toward the Threshold?

All persons employed in or in connection with the work of the establishment count toward the 10-employee threshold, including:

• Full-time employees
• Part-time employees
• Contract workers deployed at the establishment
• Casual workers
• Apprentices under the Apprentices Act (in some states)

The employer cannot exclude workers from the headcount based on employment type.

Voluntary Coverage

Establishments with fewer than 10 employees can voluntarily register with ESIC. Once registered voluntarily, the establishment cannot withdraw from the scheme.

Rate History

ESI rates have reduced significantly over the decades:

• 1948-2019: Employer 4.75%, Employee 1.75% (total 6.5%)
• July 2019 onward: Employer 3.25%, Employee 0.75% (total 4.0%)

The 2019 reduction was intended to bring more establishments into compliance by lowering the cost burden.

What is "Gross Wages" for ESI?

Under the ESI Act, contributions were calculated on gross wages including all remuneration paid or payable in cash, including overtime, but excluding only a narrow list of items (contribution paid by employer to pension/PF, traveling allowance, and gratuity).

Under the Social Security Code 2020, the definition of "wages" has changed. The new definition (Section 2(88)) provides:

• Included: All remuneration expressed in money: basic, DA, retaining allowance, and any other allowance unless specifically excluded
• Excluded: Bonus, HRA, conveyance allowance, overtime allowance, commission, gratuity, retrenchment compensation, employer PF/pension contributions
• 50% Cap Rule: If the total excluded components exceed 50% of total remuneration, the excess amount is added back to wages

This 50% cap is the most significant change for employers. If your CTC structure has exclusions exceeding 50% of total pay, your ESI-liable wages increase under the SS Code.

When an Employee Crosses the Wage Ceiling

If a covered employee receives a salary increment that takes gross wages above Rs 21,000 during a contribution period:

• The employee continues to be covered until the end of that contribution period (September 30 or March 31)
• Contributions continue at 4% of the new (higher) gross wages for the remaining months of the contribution period
• The employee exits ESI coverage from the start of the next contribution period
• Benefits accrued during the contribution period remain available during the corresponding benefit period

Contribution Periods and Benefit Periods

ESIC operates on a fixed six-month cycle that links contribution periods to benefit periods with a three-month gap.

Why This Matters for Employers

• A new employee who joins in April and contributes for at least 78 days becomes eligible for sickness benefit starting January of the following year
• Medical benefit (free treatment at ESIC hospitals) starts from Day 1 with no minimum contribution requirement
• If an employee leaves mid-contribution period, benefits remain available for the corresponding benefit period provided the 78-day minimum was met

Benefits Under ESIC

1. Medical Benefit

From the first day of insurable employment, the covered employee and their entire family receive free medical treatment at ESIC hospitals, dispensaries, and empaneled private hospitals.

Family coverage includes:

• Spouse
• Children (no age limit if dependent)
• Dependent parents
• Father-in-law and mother-in-law of women employees (added under SS Code 2020)

Medical benefit continues for retired or permanently disabled insured persons and their spouses if they have contributed for at least 5 years.

2. Sickness Benefit

Cash compensation at 70% of wages for up to 91 days in any two consecutive benefit periods.

Extended sickness benefit at 80% of wages for up to 2 years for specified long-term diseases (tuberculosis, leprosy, mental illness, malignant diseases, and others on the notified list).

Eligibility: Minimum 78 days of contribution in the relevant contribution period.

3. Maternity Benefit

Full wages (100%) for 26 weeks for the first two children, and 12 weeks for the third child onward. For adoption and commissioning mothers, 12 weeks of paid leave.

Eligibility: Minimum 70 days of contribution in the two preceding contribution periods.

Maternity benefit under ESIC is separate from and in addition to the Maternity Benefit Act provisions. However, an employee cannot claim under both simultaneously.

4. Disablement Benefit

Temporary disablement: 90% of wages from Day 1 of the injury until the employee recovers or the disablement is declared permanent.

Permanent disablement: 90% of wages for life (or as long as the disablement lasts), proportionate to the loss of earning capacity as assessed by a Medical Board.

5. Dependants' Benefit

If a covered employee dies due to an employment injury or occupational disease, 90% of wages is paid monthly to eligible dependants:

• Widow/widower (for life or until remarriage)
• Widower (added under SS Code 2020)
• Children (until age 25)
• Dependent parents
• Grandparents (added under SS Code 2020)

6. Funeral Expenses

Rs 15,000 is paid to the person who performs the last rites of a deceased insured person. This is payable from Day 1 of insurable employment with no minimum contribution requirement.

Benefit Summary Table

Monthly Filing Obligations

Contribution Deposit (By 15th of Following Month)

Every month, the employer must:

1. Calculate ESI on gross wages for all covered employees
2. Deduct 0.75% from each covered employee's gross wages
3. Add 3.25% employer contribution
4. Generate the challan on the ESIC portal
5. Pay via net banking or UPI by the 15th of the following month

Example: For wages paid in August 2026, the ESI deposit is due by 15 September 2026.

Half-Yearly Returns (11 May and 11 November)

Employers must file half-yearly returns covering the contribution periods:

The half-yearly return includes:

• Employee-wise contribution details
• Changes in employee status (new joiners, exits, salary revisions)
• Total contributions deposited during the period

Employee Registration (Within 10 Days of Joining)

Every new employee earning within the wage ceiling must be registered on the ESIC portal within 10 days of joining. The employer must:

1. Collect Form 1 (Declaration Form) from the employee
2. Upload employee details including Aadhaar, bank account, and family nominee details
3. Generate the employee's Insurance Number (IP Number)
4. Issue the ESIC e-Pehchan card to the employee

Penalties for Non-Compliance

Interest on Delayed Payment

Simple interest at 12% per annum is charged for every day of delay beyond the 15th of the following month. This interest is mandatory and cannot be waived.

Damages (Graded by Delay Period)

Both interest and damages apply simultaneously on the same unpaid amount.

Criminal Penalties Under SS Code 2020

The SS Code treats non-deposit of employee contributions (deducted from wages but not deposited with ESIC) as the most serious offence because the employer has effectively misappropriated the employee's money.

Practical Impact

An employer who delays ESI payment by 4 months on a monthly liability of Rs 50,000 faces:

• Interest: Rs 50,000 x 12% x (4/12) = Rs 2,000
• Damages: Rs 50,000 x 10% x (4/12) = Rs 1,667
• Total additional liability: Rs 3,667 over and above the principal contribution

For persistent defaulters, ESIC can attach bank accounts, file criminal complaints, and recover dues as arrears of land revenue.

Social Security Code 2020: What Changed for ESI

The Code on Social Security, 2020 (Act No. 36 of 2020) received Presidential assent on 28 September 2020 and came into force on 21 November 2025. It repeals and replaces the ESI Act 1948 along with seven other laws.

Key Changes

1. Expanded Definition of "Family"

Under the ESI Act, "family" for medical benefit included spouse, children, and dependent parents. The SS Code adds:

• Father-in-law and mother-in-law of women employees (Section 2(33)(e))

Women employees can now add in-laws to their ESIC records for medical benefits.

2. Expanded Definition of "Dependant"

For dependent benefit (paid to survivors on employee death from employment injury), the SS Code now includes:

• Widower (previously only widow was covered)
• Grandparent (previously not covered)

This took effect on 21 November 2025 via ESIC Circular No. N-11011/2/2025-BFT-II dated 28 November 2025.

3. Uniform Wages Definition with 50% Cap

The SS Code introduces a unified "wages" definition across all social security schemes. The critical rule: if excluded components (bonus, HRA, conveyance, overtime, commission) exceed 50% of total remuneration, the excess is added back to "wages" for contribution calculation.

Impact on employers: If your salary structure allocates more than 50% to allowances and variable components, your ESI-liable wages will increase.

4. Gig Workers and Platform Workers

The SS Code extends social security coverage to gig workers (outside traditional employer-employee relationships) and platform workers (working through digital platforms). ESIC is planning to bring these workers under the ESI benefit framework through separate notifications.

As of August 2026, the gig/platform worker provisions have not been fully operationalised. Aggregator companies will be required to contribute a notified percentage of annual turnover to a social security fund.

5. Inspector-cum-Facilitator

The inspector role has been redesigned as "Inspector-cum-Facilitator" with a dual mandate: compliance enforcement AND employer guidance. Web-based random inspection allocation reduces discretionary visits.

What Has NOT Changed

• Contribution rates: 3.25% employer, 0.75% employee (unchanged)
• Wage ceiling: Rs 21,000 (unchanged)
• Establishment threshold: 10 employees (unchanged)
• Benefit rates: 70% sickness, 100% maternity, 90% disability (unchanged)
• Filing deadlines: 15th of following month for contributions (unchanged)

Transition Timeline

ESIC Amnesty Scheme 2025

The ESIC Amnesty Scheme 2025 provides a one-time opportunity to resolve old disputes with reduced financial liability.

Period: 1 October 2025 to 30 September 2026

Eligibility: Cases filed up to 31 March 2025 covering both running and closed establishments.

Key Relief:

• Ad-hoc assessments: Pay actual contributions + interest only. No damages.
• Cases already paid: Settlement by paying 10% of disputed damages.
• Closed units (5+ years with pending litigation): Cases withdrawn without payment.
• Closed units (within 5 years): Produce records, pay dues with interest. No damages.
• Contribution disputes: Pay contributions + interest. No damages if records produced.
• Missing records: Payment of at least 30% of assessed contribution. No damages.

If your establishment has old ESIC disputes (assessment orders, show-cause notices, or court cases filed before March 2025), this is the most cost-effective resolution window available before the scheme expires on 30 September 2026.

Common Employer Mistakes

1. Not registering because "all employees earn above Rs 21,000"

If even one employee (including a contract worker, peon, or security guard deployed by a contractor) earns within the ceiling, the establishment must register. The threshold is about the establishment's total headcount, not whether all employees are covered.

2. Calculating ESI on basic instead of gross

ESI is calculated on gross wages (all remuneration in cash) including overtime. Unlike PF which uses basic + DA, ESI uses a broader base. Underpaying due to wrong calculation base attracts interest and damages on the differential.

3. Not removing exited employees from the portal

Employees who leave must be marked as "left" on the ESIC portal. Failing to do so means the half-yearly return shows them as active, and any discrepancy with actual contributions filed triggers queries from the regional office.

4. Ignoring the 50% cap under SS Code

If your salary structure has more than 50% in excluded components, the excess counts as wages for ESI. Many employers have not restructured CTC breakdowns after November 2025. An ESIC inspection under the new wages definition will assess arrears on the differential.

5. Treating ESI as optional below the wage ceiling

Once the establishment is registered, every employee earning within the ceiling must be covered. The employer cannot selectively exclude employees. Even probationary employees, temporary staff, and workers on notice period must contribute.

6. Missing the contribution period transition

When an employee's salary crosses Rs 21,000, they exit coverage only at the start of the next contribution period (April 1 or October 1). Stopping contributions mid-period is incorrect and triggers deficiency notices.

Tax Implications for Employers

Deduction Under Section 36(1)(va) and 43B

Employer ESI contributions deposited on or before the due date of filing the income tax return are deductible under Section 43B. Employee contributions deducted from wages must be deposited by the due date under the ESI Act (15th of the following month) to claim deduction under Section 36(1)(va).

If the employer deposits the employee's share after the 15th:

• The employee's share is disallowed permanently under Section 36(1)(va) per the Supreme Court ruling in Checkmate Services (2022)
• The employer's share remains deductible if deposited before the ITR due date under Section 43B

This distinction between employer and employee shares is critical for tax planning. Late ESI deposits cost you both the penalty from ESIC and the income tax disallowance.

Section 80C Benefit for Employees

Employee ESI contributions do not qualify for Section 80C deduction (unlike PF contributions). This is a common misconception.

Compliance Checklist for Employers

1. Register on ESIC portal within 15 days of crossing 10-employee threshold
2. Register every eligible employee (wages up to Rs 21,000) within 10 days of joining

9. Track salary revisions: when an employee crosses Rs 21,000, continue coverage until the end of the contribution period
10. Review CTC structure for 50% cap compliance under SS Code wages definition
11. Maintain records: wage register, attendance register, contribution register for a minimum of 5 years
12. Respond to ESIC inspection notices within 15 days
