Employee State Insurance (ESI) Contributions

India’s social security framework for organised sector employees rests on two primary pillars – the Employees’ Provident Fund for retirement savings, and the Employees’ State Insurance scheme for health and income protection. EPF gets discussed more often, probably because it touches a larger salaried population. But ESI, administered by the Employees’ State Insurance Corporation, is the scheme that matters most to an employee in the moments that count – when they are sick, injured, pregnant, disabled, or facing unemployment.

For employers, ESI is a monthly payroll obligation that sits alongside professional tax, TDS, and PF contributions as a core compliance requirement. The consequences of getting it wrong – whether by missing the wage threshold, misclassifying employees, or simply remitting late – are well documented and actively enforced by the ESIC.

What makes ESI genuinely interesting from a compliance perspective is its scope. The scheme is not just about contributions. It is a complete social insurance system – a parallel healthcare infrastructure, an income replacement framework, a rehabilitation network – all funded through the contributions that flow through employer payrolls every month.

This guide covers all of it.

Mercans provides fully managed Indian payroll services, including accurate ESI calculation, ESIC portal submissions, and compliance management for employers across all applicable states and industries in India.

The Legal Foundation – What Is ESI?

The Employees’ State Insurance (ESI) scheme is established and governed by the Employees’ State Insurance Act, 1948 – one of India’s foundational pieces of labour legislation. It is administered by the Employees’ State Insurance Corporation (ESIC), an autonomous body under the Ministry of Labour and Employment.

The ESI Act applies to non-seasonal factories employing ten or more persons, and to establishments in certain notified industries and areas employing ten or more persons. The Central Government periodically extends the scheme’s coverage to new categories of establishments and geographical areas through gazette notifications, meaning the scope of ESI applicability has expanded significantly since 1948 and continues to do so.

The scheme operates on an insurance principle – contributions are made during employment, and benefits are drawn when qualifying conditions are met. Unlike some social security schemes that function as savings instruments, ESI is genuinely insurance – the benefit an employee receives is not proportional to their contributions but is determined by the qualifying event and the coverage the scheme provides.

Coverage – Who Is Covered

Establishments Covered

ESI applies to:

• Factories – any premises where manufacturing processes are carried on with ten or more employees, seasonal or otherwise
• Shops, hotels, restaurants, cinemas, road motor transport undertakings, newspaper establishments and other entities employing ten or more persons in areas where the scheme has been extended
• Private educational institutions and medical institutions employing ten or more persons where the scheme has been notified

The ten-person threshold is a frequent source of compliance questions. Once an establishment crosses the threshold and becomes covered, it remains covered even if headcount later falls below ten. The coverage, once triggered, is not reversed simply because employment levels fluctuate.

Employees Covered – The Wage Threshold

Within a covered establishment, individual employees are covered by ESI if their gross monthly wages do not exceed Rs. 21,000. This threshold – often called the wage ceiling or coverage limit – was last revised to Rs. 21,000 per month with effect from 1 January 2017.

For employees with disabilities, the threshold is higher at Rs. 25,000 per month, reflecting a policy intent to extend coverage to a broader population of differently-abled workers.

An employee whose wages exceed the applicable threshold is not covered by ESI and no contributions are made on their behalf. An employee who starts below the threshold and receives a salary increase that takes them above it during the contribution period continues to be covered until the end of that half-year contribution period, at which point they exit coverage if they remain above the threshold.

What Counts as Wages for ESI Purposes

The definition of wages under the ESI Act is broad and encompasses more than basic salary. Wages for ESI purposes include:

• Basic salary
• Dearness allowance
• City compensatory allowance
• House rent allowance
• Overtime wages – though overtime is included in wages for contribution purposes but excluded from the wage ceiling assessment when determining coverage
• Incentives and production bonuses paid at regular intervals
• Night shift allowance and similar fixed regular payments

Certain payments are specifically excluded from ESI wages:

• Annual or semi-annual bonuses not paid at regular intervals (Diwali bonus, production bonus paid annually)
• Contributions paid by the employer under any pension or provident fund scheme
• Travelling allowance or reimbursement of travel expenses
• Gratuity payable on discharge
• Any daily allowance paid for the period during which the employee is on tour

The distinction between included and excluded components requires careful payroll configuration. Including a component that should be excluded inflates the contribution base – excluding one that should be included understates it. Both create compliance exposure in ESIC audits.

Contribution Rates – Current Structure

ESI contributions are shared between employer and employee at rates prescribed under the ESI Act and revised periodically by the Central Government.
These rates were revised with effect from 1 July 2019, when the employer rate was reduced from 4% to 3.25% and the employee rate from 1% to 0.75%, as part of a policy initiative to reduce the compliance cost burden on employers and increase take-home pay for employees.

Exemption for Low-Wage Employees

Employees whose daily wage is Rs. 176 or less (the threshold equivalent to approximately Rs. 5,280 per month at 30 days) are exempt from the employee contribution of 0.75%. The employer contribution of 3.25% continues to apply even for these employees – only the employee share is waived, not the employer share.

This exemption is meaningful for employers with significant numbers of low-wage workers – it reduces the deduction from their already modest take-home pay while preserving their ESI coverage.

The Contribution Period and Benefit Period Framework

ESI operates on a distinctive two-period structure that links contribution history to benefit entitlement. This is one of the features that distinguishes ESI from simpler statutory deduction schemes.

Contribution Periods

The year is divided into two contribution periods:

• First contribution period: 1 April to 30 September
• Second contribution period: 1 October to 31 March

Contributions made during each period determine the employee’s eligibility for benefits in the corresponding benefit period that follows.

Benefit Periods

• First benefit period: 1 January to 30 June (corresponding to contributions from April to September of the prior year)
• Second benefit period: 1 July to 31 December (corresponding to contributions from October to March)

There is a three-month lag between the end of the contribution period and the start of the corresponding benefit period – this gap allows ESIC to process contribution records and establish benefit eligibility before the benefit period opens.

Practical Implications for Employees

An employee who has contributed during the first contribution period (April to September) becomes entitled to benefits in the first benefit period of the following year (January to June). For sickness benefit specifically, the employee must have paid contributions for at least 78 days in the relevant contribution period to be eligible for the full benefit entitlement in the corresponding benefit period.

For employers, this framework means that new employees who join mid-year may not immediately be eligible for certain ESI benefits – their benefit entitlement develops as they accumulate contribution history. Understanding this helps HR teams explain to new employees why they may not immediately be able to draw certain ESI benefits.

ESI Benefits – What Employees Actually Receive

The ESI scheme provides a comprehensive package of benefits that extends well beyond the employer and employee contributions might suggest. Benefits fall into several categories:

Medical Benefit

This is the most widely used ESI benefit. Insured employees and their dependants are entitled to full medical care at ESIC dispensaries, hospitals, and empanelled hospitals. Medical benefit includes:

• Outpatient treatment, specialist consultations, and diagnostics
• Inpatient hospitalisation including surgery
• Maternity care
• Specialist treatment and referrals
• Provision of medicines and medical devices

Medical benefit commences from the day of entering insurable employment – there is no waiting period for medical care, unlike the sickness cash benefit. This makes ESI medical coverage immediately valuable to new employees.

ESIC operates its own network of hospitals, dispensaries, and first-aid centres across India – a significant parallel healthcare infrastructure funded through the scheme’s contributions.

Sickness Benefit

Insured employees unable to work due to illness are entitled to a cash sickness benefit of 70% of daily wages for a maximum of 91 days per year during two consecutive benefit periods.

Enhanced Sickness Benefit – at 100% of wages for up to 7 days (extendable to 14 days) – is available to insured persons undergoing vasectomy or tubectomy under the family planning programme.

Extended Sickness Benefit – at 70% of wages for up to 2 years – is available for specified long-term illnesses including tuberculosis, leprosy, mental diseases, malignant diseases, and other serious chronic conditions.

Maternity Benefit

Female insured employees are entitled to:

• Maternity benefit at 100% of wages for 26 weeks – for the first two children
• 12 weeks for the third child and beyond
• 12 weeks in case of adoption of a child below three months
• 6 weeks in case of miscarriage or medical termination

The ESI maternity benefit is notably more generous in terms of replacement rate than the statutory maternity benefit under the Maternity Benefit Act – because it is paid at 100% of average daily wages rather than the Maternity Benefit Act’s prescribed rate. For ESI-covered employees, the ESI benefit takes precedence.

Disablement Benefit

Temporary Disablement Benefit – paid at 90% of wages for the full period of temporary disability arising from a work-related injury, with no duration cap.

Permanent Disablement Benefit – a monthly pension at 90% of wages, proportionate to the degree of permanent disability certified by a Medical Board, payable for the employee’s lifetime.

Dependants’ Benefit

In the event of an insured employee’s death due to an employment injury, dependants’ benefit is paid as a monthly pension to eligible dependants – widow, children, and in certain cases other dependants – at a total rate equivalent to 90% of the insured person’s wages, distributed among eligible dependants per ESIC rules.

Other Benefits

• Funeral Expenses – a lump sum of Rs. 15,000 payable to the person who performs the last rites of a deceased insured employee
• Rehabilitation Allowance – paid during vocational rehabilitation for employees with permanent disability
• Unemployment Allowance (Rajiv Gandhi Shramik Kalyan Yojana) – available to insured persons who become unemployed involuntarily due to factory closure, retrenchment, or permanent invalidity, at 50% of wages for up to 2 years

ESIC Registration – Employer Obligations

Initial Registration

Every employer covered by the ESI Act must register with the ESIC before the scheme applies to their establishment. Registration is done online through the ESIC portal (esic.in) and requires:

• Employer’s legal name and PAN
• Nature of business and industry code
• Address of each establishment to be covered
• Details of the authorised signatory

Upon successful registration, the employer receives a 17-digit Employer Code – the unique identifier used in all ESIC transactions and filings.

Employee Registration and Insurance Numbers

Each covered employee must be registered with ESIC and issued an Insurance Number (IP Number). Registration is completed through the employer’s ESIC portal account by entering the employee’s personal details, wage information, and bank account details.

The employee receives an ESI Pehchan Card (recognition card) which serves as their identification for accessing ESI medical facilities and claiming benefits. The Pehchan Card extends coverage to the employee’s dependants registered against their IP number.

Employers must register new employees within 10 days of their joining date. Delayed registration creates a gap in the employee’s coverage and exposes the employer to penalty under the ESI Act.

Monthly Compliance – The Contribution and Filing Cycle

Contribution Payment Deadline

ESI contributions – both the employer’s 3.25% and the employee’s 0.75% withheld from salary – must be deposited with the ESIC by the 15th of the month following the month in which wages are paid. Contributions for June wages are due by 15 July, and so on.

Payment is made online through the ESIC portal using the employer’s 17-digit code, generating a Challan (payment receipt) that serves as proof of remittance.

Monthly Return – Form 6

Alongside the contribution payment, employers are required to file a monthly contribution statement through the ESIC portal – commonly referred to as Form 6 filing – detailing each covered employee’s wages and the contributions made on their behalf for the month. The monthly return must reflect accurate wage data for each employee, including any changes in wages during the month.

Half-Yearly Return

In addition to monthly compliance, employers file a half-yearly return for each contribution period – April to September and October to March. The half-yearly return provides a comprehensive record of all employees covered, their contribution histories, and any changes in status during the period. This return feeds directly into the benefit eligibility calculations that determine what each employee can claim in the subsequent benefit period.

Common ESI Compliance Errors

Experience across Indian payroll operations consistently surfaces the same categories of ESI error:

Incorrect wage ceiling application: An employee who receives a salary increase mid-year that takes them above Rs. 21,000 must continue to be covered through the end of the current contribution period. Removing them from ESI coverage at the point of the salary increase rather than at the period end is incorrect.

Incorrect wage base for contributions: Including excluded components (annual bonus, gratuity, travel reimbursements) or excluding included components (HRA, city compensatory allowance) from the contribution base creates systematic over or under-contribution.

Delayed employee registration: Failing to register new employees within 10 days of joining leaves them without coverage and creates liability for unpaid contributions from the joining date.

Not contributing for casual and contract employees: Many employers incorrectly assume ESI applies only to permanent employees. Under the ESI Act, all employees of a covered establishment whose wages are below the threshold are covered – regardless of whether they are permanent, temporary, casual, or on fixed-term contracts.

Mishandling the wage ceiling for overtime: Overtime wages are included in ESI contributions but excluded from the wage ceiling determination. An employee whose basic and allowance components are below Rs. 21,000 but whose total wages including overtime exceed Rs. 21,000 remains covered – the overtime excess does not push them out of coverage.

ESI and the Contract Labour Framework

Many Indian employers engage contract workers through labour contractors rather than directly – particularly in manufacturing, logistics, and facility management. ESI compliance for contract labour is a frequently misunderstood area.

Under the Contract Labour (Regulation and Abolition) Act, 1970, the primary contractor (labour contractor) is responsible for ESI contributions for the contract workers they supply. However, if the principal employer can demonstrate that the contractor has failed to make ESI contributions for workers deployed at the principal employer’s establishment, the principal employer becomes liable for those contributions.

In practice, many principal employers protect themselves by:

• Requiring contractors to provide monthly proof of ESI contribution – challan copies covering the workers deployed
• Deducting the ESI liability from contractor invoices where proof is not provided, and remitting directly
• Including ESI compliance obligations explicitly in contractor agreements

The liability exposure for principal employers in the contract labour ESI context is real and regularly arises in ESIC inspections. A principal employer cannot simply point to the contractor and consider themselves protected without evidence that contributions were actually made.

Inspection, Audit, and Enforcement

ESIC has the authority to conduct inspections of employer premises and records. Inspectors can:

• Examine payroll registers, muster rolls, and wage records
• Verify that all covered employees are registered with correct IP numbers
• Check contribution payment records against payroll data
• Issue assessment orders for unpaid or underpaid contributions

Interest on late payments: 12% per annum on contributions not paid by the 15th of the following month.

Penalty for non-payment or delayed payment: Up to Rs. 5,000 per default – assessed per violation, not per employee, meaning systematic non-compliance generates compounding penalty exposure.

Prosecution: Under Section 85 of the ESI Act, deliberate non-compliance – failing to register, failing to pay contributions, falsifying records – can result in imprisonment of up to 2 years and fines.

ESIC inspectors have access to payroll data and can compare declared wages against other tax filings – including TDS returns and PF contribution records – to identify discrepancies that may indicate under-reporting.

How Mercans Manages ESI Compliance Across India

ESI compliance is not a single national obligation – it varies in application across states, industries, and establishment types, and requires continuous monitoring of ESIC notifications extending coverage to new categories and areas. For employers with operations across multiple Indian states, maintaining consistent ESI compliance requires a payroll engine that is both nationally aware and locally precise.

Mercans’ India payroll services manage ESI compliance end to end:

• ESIC employer registration for each applicable establishment
• Employee registration and IP number generation within the 10-day deadline
• Accurate contribution base calculation – correctly including and excluding wage components per ESI Act definitions
• Monthly challan generation and contribution payment by the 15th deadline
• Monthly Form 6 return filing through the ESIC portal
• Half-yearly return preparation and submission for both contribution periods
• Wage ceiling monitoring – tracking employees approaching or crossing the Rs. 21,000 threshold and managing the transition correctly across contribution period boundaries
• Contract labour ESI compliance monitoring – verifying contractor contributions for workers at client establishments
• ESI Pehchan Card facilitation for newly registered employees

For multinational employers managing Indian operations as part of a broader APAC or global payroll programme, Mercans’ global payroll platform provides India-specific ESI compliance depth integrated within a unified international reporting framework. Learn more at mercans.com.

Frequently Asked Questions

Does ESI apply to employees working from home or in remote locations if the employer’s establishment is covered?

The ESI Act’s coverage is determined by the establishment’s status, not the employee’s work location. If an employer’s establishment is a covered factory or notified establishment, employees of that establishment who earn below the wage ceiling are covered – regardless of whether they work on-site, from home, or from a remote location. The work-from-home expansion following the pandemic raised this question for many employers, and the ESIC’s position is that remote working does not affect an employee’s ESI coverage status. Their contributions continue, their IP numbers remain active, and they are entitled to access ESI medical facilities and claim benefits through the standard process.

What happens when an employee’s salary increases above Rs. 21,000 mid-year?

An employee who crosses the Rs. 21,000 wage ceiling during a contribution period does not exit ESI coverage immediately. They remain covered through the end of the current contribution period – either 30 September or 31 March, whichever comes next. Contributions continue to be made on their wages for the remainder of the period even though those wages now exceed the ceiling. At the start of the next contribution period, the employee exits ESI coverage and no further contributions are made. The employer must update the employee’s status in the ESIC portal at the start of the new period. Importantly, the employee retains benefit eligibility in the benefit period corresponding to their final contribution period – so an employee who exits coverage in September retains benefit entitlement through the subsequent January-to-June benefit period.

Are directors and partners of companies or firms covered by ESI?

The ESI Act covers employees – persons employed for wages in connection with the work of a covered establishment. The coverage of directors and partners depends on their specific relationship with the entity. A director who is also an employee – drawing a salary, subject to control and supervision, and performing duties like an employee – is generally covered if their wages fall below the threshold. A director who is purely a shareholder or nominal director without a working relationship may not be. Proprietors, partners of a partnership firm, and sole traders are not covered as they are not employees. Where the status is ambiguous – particularly for working directors – employers should seek formal ESIC guidance or legal advice rather than making their own determination, as incorrect exclusion creates liability from the date the working relationship began.

Can an employee opt out of ESI if they have private health insurance?

No. ESI coverage and contributions are mandatory for all eligible employees in covered establishments – there is no opt-out mechanism regardless of the employee’s personal health insurance arrangements. The fact that an employee has superior private health coverage does not exempt them from ESI. Both the employer and employee must continue to make their respective contributions. Some employees find this frustrating, particularly those with comprehensive corporate health insurance plans who see ESI as duplicative coverage. The employer’s role is to apply the law correctly – ESI contributions are not discretionary and cannot be waived on the basis of alternative coverage arrangements.

How does ESI interact with the Maternity Benefit Act for covered employees?

For employees covered by ESI – those in covered establishments earning below the wage ceiling – the ESI scheme’s maternity benefit provisions take precedence over the Maternity Benefit Act. The employer is not required to pay maternity benefits directly under the Maternity Benefit Act for ESI-covered employees, because their maternity benefit entitlement is funded and administered through the ESIC. The employee claims maternity benefit directly from ESIC rather than from the employer. The employer’s obligation is to ensure contributions have been correctly made so the employee’s benefit entitlement is properly established, and to facilitate the claim process. For employees who are not ESI-covered – because their wages exceed the Rs. 21,000 threshold or because the establishment is not covered – the Maternity Benefit Act applies in full and the employer pays the benefit directly. Mercans’ India payroll team helps employers correctly identify which regime applies to each employee and manage the compliance obligations accordingly.
