ESI (Employees State Insurance) Registration

ESI registration is a statutory compliance requirement under the Employees State Insurance Act, 1948, administered by the Employees State Insurance Corporation (ESIC). Any establishment employing 10 or more persons (20 or more in some states) and engaged in manufacturing, mining, or covered service activities must register with ESIC. Employers contribute 3.25% of gross wages and employees contribute 0.75%, providing workers with medical care, sickness cash benefits, maternity benefits, and disablement benefits. In government procurement, ESI registration is a mandatory eligibility document in most NITs, placed alongside EPF registration as proof that the bidder meets its labour law obligations.

What is ESI registration in government procurement?

When an NIT requires ESI compliance documentation, the bidder must submit its ESIC employer code, a unique identifier issued at registration, and usually the most recent ESI contribution challan (proof of payment). The ESI employer code appears on the ESIC portal and on all payment challans. Some NITs ask for an ESIC compliance certificate or a statement of contributions for the past financial year.

ESIC registration is done online through the ESIC unified shram suvidha portal. After approval, the employer receives a code number. Contributions are due twice a year in aggregate, but monthly challan payments are standard practice. Establishments must also register each covered employee and issue an ESI card (called the Pehchaan card) that employees use to access ESIC medical facilities.

The government procurement system requires ESI documents for the same reason it requires EPF documents, to ensure the contractor is not running an informal workforce and to protect the government department from principal employer liability under the Contract Labour Act. If a contractor deployed on a government project fails to pay ESI contributions, ESIC can recover dues from the principal employer (the government department).

Contractors operating in states or sectors where ESI coverage is not yet implemented (some rural areas and sectors are still outside ESI coverage) may need to submit a declaration explaining why ESI is not applicable, along with any relevant ESIC notification. However, for most urban infrastructure and service contracts, ESI coverage is expected.

Why it matters for bidders

Missing ESI documentation is one of the most common causes of technical bid rejection, particularly for service contracts such as security, housekeeping, facility management, catering, and manpower supply, sectors where the workforce is large and the statutory compliance burden is high. Bid evaluators check for the employer code certificate and the most recent challan as a basic document compliance step.

Bidders who hold multiple registrations across states must ensure that they submit the correct state-wise ESIC codes depending on where the workers will be deployed. A single head-office ESIC code may not satisfy a requirement for a project in a different state, so bidders should check whether the NIT requires proof of registration in the state of project execution.

Maintaining a regularly updated compliance file, with ESIC payment challans sorted by month, makes bid assembly faster and reduces the risk of submitting a stale document.

Example

A central PSU floats a tender for security guard services at its plant spread across three shifts, with approximately 150 personnel to be deployed, and an estimated annual contract value of Rs 2.8 crore. The NIT mandates valid EPF and ESI registration certificates along with challans for the previous three months. A bidder with only 8 employees currently on its rolls (because it operates project-based) may technically be below the threshold for mandatory ESI coverage, but winning this contract would immediately bring it above 10 employees. The bidder should register with ESIC proactively before submitting its bid and include the registration certificate in Cover 1.

Key rules / thresholds

• ESI is mandatory for establishments with 10 or more employees in most states (20 in a few states for certain sectors).
• Employer contribution rate: 3.25% of gross wages. Employee contribution: 0.75% of gross wages.
• Workers earning above Rs 21,000 per month (gross) are exempt from ESI coverage.
• Monthly contribution payments are deposited through the ESIC portal; late payment attracts interest and damages.
• Establishments in areas without ESIC dispensaries are still required to register once they cross the threshold, ESIC provides cashless treatment through tie-up hospitals where dispensaries are unavailable.
