A manufacturing company in Pune is being acquired through a slump sale. The buyer's due diligence team asks: "What happens to the ESIC registration? Do we inherit the previous owner's ESIC liabilities? Do employees lose their ESI benefits during the transition? And what do we need to do on the ESIC portal?"
These are practical questions that arise in every business acquisition, merger, or restructuring - and almost no online resource answers them comprehensively. The ESI Act has specific provisions for transfer of establishments (Section 97), but the practical implementation - what to do on the portal, how to handle the transition period, how to protect the acquiring company from hidden liabilities - requires professional guidance.
This blog explains the complete framework: when and how ESIC compliance transfers, what the law says, what the new owner must do, and the due diligence checklist that protects both the business and its employees.
What Is ESIC and Why Does Transfer Matter?
The Employees' State Insurance (ESI) scheme is India's social security system for workers earning up to Rs 21,000/month (Rs 25,000 for disabled persons). It provides medical benefits, sickness cash benefits, maternity benefits, disability benefits, and dependent benefits. Employers contribute 3.25% and employees contribute 0.75% of wages - a combined 4% that funds the entire system.
When a business changes hands - through merger, acquisition, slump sale, asset purchase, or demerger - the ESIC compliance framework is directly affected because: (a) the employer-employee relationship changes (new entity becomes the employer), (b) the ESIC registration is linked to the establishment and employer code, (c) ongoing contribution obligations shift to the new entity, and (d) pre-existing liabilities (unpaid contributions, pending inspections, disputed assessments) may transfer with the business.
Businesses using ESIC registration services (know more) get support for both initial registration and transfer-related compliance.
Key Terms You Should Know
Section 97 (ESI Act, 1948): The transfer liability provision. When an establishment is transferred, the new owner (transferee) is jointly and severally liable with the old owner (transferor) for any amounts due under the Act up to the date of transfer.
Employer Code: The unique registration number assigned to an establishment under ESIC. In a share purchase, the employer code remains the same. In a slump sale or asset purchase, a new employer code is required.
Insurance Number (IP Number): The unique number assigned to each insured employee. This is linked to the employee - not the employer. Benefits follow the IP number regardless of employer change.
Contribution Period: The 6-month period (April-September and October-March) during which contributions are paid. Benefits in the corresponding benefit period depend on contributions made during the contribution period.
Benefit Period: The 6-month period following the contribution period during which employees are eligible for benefits based on contributions already paid. A business transfer during the contribution period does not interrupt the benefit period.
Slump Sale: Transfer of a business undertaking as a going concern - all assets and liabilities transfer to the buyer for a lump sum consideration. ESIC registration does not automatically transfer; new registration required.
Share Purchase: Transfer of ownership by purchasing shares of the company. The company entity remains the same - ESIC registration continues unchanged.
When Does ESIC Transfer Apply?
| Type of Business Change | ESIC Registration | Liability Transfer (Section 97) | Employee Coverage |
|---|---|---|---|
| Share purchase (100% buyout of Pvt Ltd/LLP) | Continues as-is - same entity, same employer code | Not triggered (no 'transfer of establishment' - same legal entity continues) | Uninterrupted - same employer, same registration |
| Slump sale (business sold as going concern) | New registration required by buyer; old registration continues for old owner's other businesses | Yes - Section 97 applies; buyer jointly liable for pre-transfer arrears | Continues under new employer; employees must be mapped to new employer code |
| Asset purchase (selected assets bought) | New registration by buyer; old registration remains with seller | Depends on whether employees are transferred; if yes, Section 97 may apply | Employees who transfer to buyer get new employer mapping; those who stay retain old coverage |
| Merger / Amalgamation (two companies merge) | Surviving entity's registration continues; merged entity's registration must be surrendered | Yes - Section 97 applies; surviving entity inherits all ESIC liabilities | Uninterrupted - all employees transfer to surviving entity |
| Demerger (one company splits into two) | Resulting entities need separate registrations for their respective establishments | ESIC liabilities apportioned per demerger scheme; NCLT order governs allocation | Employees allocated per demerger scheme; coverage continues under respective entity |
| Change of proprietor (sole proprietorship sold) | New registration required - proprietorship is not a separate legal entity | Yes - Section 97 applies fully; new proprietor inherits all ESIC obligations | Continues if new proprietor retains employees and meets threshold |
| Partnership reconstitution (partner entry/exit) | Intimation to ESIC required; same registration may continue if PAN/entity continues | Incoming partner shares liability for pre-existing arrears under partnership law + Section 97 | Uninterrupted - same establishment continues |

Section 97 of the ESI Act: The Transfer Liability Rule
Section 97 is the critical provision that governs ESIC liability transfer. It states:
"Where an employer, by whom contributions are payable under this Act in respect of an employee, transfers his establishment to another person, the employer and the transferee shall jointly and severally be liable to pay the contributions due in respect of the employee for the period up to the date of transfer."
Practical implications of Section 97:
- The new owner cannot negotiate away ESIC liability - it transfers by operation of law regardless of what the acquisition agreement says between the parties. Even if the sale deed says 'all liabilities remain with the seller,' ESIC can still pursue the buyer.
- The liability is joint and several - ESIC can pursue either the old owner or the new owner or both for pre-transfer arrears.
- The liability covers: unpaid contributions, interest on delayed payments (12% p.a.), damages for non-payment, and any assessment orders pending.
- The transferee's liability is limited to amounts due 'up to the date of transfer.' Post-transfer contributions are the new owner's sole responsibility.
- Under the Code on Social Security, 2020 (once fully operational), similar transfer provisions apply - the principle of joint liability on transfer is retained.
Step-by-Step: What to Do When the Business Changes Hands
Step 1: Pre-Transfer Due Diligence. Before completing the acquisition, the buyer must verify: (a) current ESIC registration status (active/inactive/suspended), (b) contribution payment history for at least 3 years, (c) pending ESIC inspections or show cause notices, (d) disputed assessments or appeals, (e) number of covered employees and wage details, (f) compliance with half-yearly returns (Form 01-RA). Use statutory audit (know more) services for pre-acquisition ESIC due diligence.
Step 2: Quantify Pre-Transfer Liabilities. Calculate any arrears: unpaid contributions for all covered employees for all pending months, interest at 12% p.a. on delayed payments, and any damages assessed but unpaid. This amount should be factored into the purchase price negotiation - either as a price reduction or held in escrow.
Step 3: Determine Registration Approach. Share purchase: no action needed on ESIC registration - same entity continues. Slump sale/asset purchase: buyer must apply for fresh ESIC registration within 15 days of the transfer date. Merger: surviving entity continues; merged entity's registration surrendered. Use company registration (know more) services for entity restructuring support.
Step 4: Employee Mapping to New Employer Code. For slump sale/asset purchase: each employee's IP number must be mapped to the buyer's new employer code on the ESIC portal. This ensures uninterrupted coverage and benefit eligibility. The mapping requires: employee name, IP number, date of transfer, and the new employer code.
Step 5: Clear Pre-Transfer Arrears. The cleanest approach: the seller pays all ESIC arrears before the transfer date, and the buyer verifies payment on the portal. If the seller cannot pay, the buyer can: (a) withhold the arrears amount from the purchase price and pay ESIC directly, or (b) create an escrow mechanism where the arrears are paid from held funds.
Step 6: File Intimation with ESIC. Notify the local ESIC branch office of the transfer: identity of the new owner, date of transfer, list of employees transferred, and confirmation that the new registration (if needed) has been obtained. There is no prescribed form for this - a letter to the Regional Director with supporting documents suffices.
Step 7: Continue Monthly Compliance. From the transfer date, the new owner must: calculate and deposit monthly ESIC contributions by the 15th of the following month, file half-yearly returns, and maintain the Accident Register (Form 12), Inspection Book, and other prescribed registers. Use payroll management (know more) services for ongoing ESIC compliance.
Step 8: Post-Transfer Reconciliation. Within 3 months of transfer, reconcile: all employees are covered under the new registration, contribution history is intact on the portal, no coverage gaps exist for any employee, and benefit period eligibility is uninterrupted.
Documents Required During ESIC Business Transfer
- ESIC registration certificate of the old owner (Form 01)
- Contribution payment challans for the last 3 years
- Half-yearly returns (Form 01-RA) for the last 6 contribution periods
- Employee register with IP numbers, wages, and coverage dates
- Inspection reports and show cause notices (if any)
- Assessment orders and appeal records (if any)
- Transfer agreement (sale deed / slump sale agreement / merger order)
- NCLT order (for mergers and demergers)
- New ESIC registration application (for slump sale / asset purchase)
- Employee consent / transfer letters (where individual consent is needed)
- Payroll records for the transition month (to verify coverage continuity)
- Form 26AS / AIS (for cross-checking TDS on ESIC-related transactions)
What Happens to Employees During the Transfer?
| Employee Aspect | What Happens | Action Required |
|---|---|---|
| ESI coverage | Continues uninterrupted - 'once covered, always covered' rule applies as long as wages are within ceiling and establishment meets threshold | Map employee IP numbers to new employer code on ESIC portal |
| Contribution history | Linked to IP number, not employer code. History is intact regardless of employer change. | No action - contribution history follows the employee |
| Benefit period eligibility | Based on contributions in the preceding contribution period. Transfer does not reset this. | Ensure no gap in contributions during the transition month |
| ESI card | Existing ESI card (Pehchan card) remains valid. New employer details updated on portal. | Update employer details on ESIC portal; employee does not need a new card |
| Medical benefits | Continue at the same ESI dispensary/hospital. No change in coverage. | No action - medical benefits are location-linked, not employer-linked |
| Maternity/sickness claims | If a claim was pending with old employer, the new employer must support the continuation. ESIC processes based on IP contribution history. | New employer must submit any pending claim forms with the ESIC office |
| Wages exceeding Rs 21,000 post-transfer | If the new employer revises wages above Rs 21,000, the employee exits ESI coverage - but only from the next contribution period, not immediately | Track wage changes post-transfer; update eligibility status |
ESIC Contribution Rates and Calculation During Transfer
The ESIC contribution rates remain the same regardless of ownership change:
- Employer contribution: 3.25% of wages
- Employee contribution: 0.75% of wages
- Total: 4% of wages
- Wage ceiling: Rs 21,000/month (Rs 25,000 for disabled employees)
- Wage definition (Code on Social Security 2020): Basic + DA; if allowances exceed 50% of total remuneration, excess is added back to wages
During the transfer month: contributions must be paid for the full month without interruption. If the transfer happens mid-month (say 15th), the old employer is responsible for contributions up to the 14th and the new employer from the 15th - but practically, the month's contribution is typically settled between the parties in the acquisition agreement.
Critical: no contribution gap is permitted during transfer. If neither party pays for the transition month, ESIC charges interest (12% p.a.) and damages (up to the unpaid amount). The liability falls on both parties under Section 97.
Common Mistakes During ESIC Business Transfer
Mistake 1: Not conducting ESIC due diligence before acquisition. The buyer inherits ESIC arrears under Section 97 regardless of indemnity clauses in the sale agreement. If the seller had unpaid contributions for 12 months (say Rs 8 lakh for 50 employees), the buyer is jointly liable for this amount plus 12% interest plus damages.
Mistake 2: Assuming share purchase eliminates ESIC transfer issues. In a share purchase, the ESIC registration continues - but any pre-existing arrears also continue within the same entity. The new shareholders are not personally liable (limited liability), but the company remains liable. The unpaid amount must still be addressed.
Mistake 3: Creating a contribution gap during the transition period. If the old owner stops paying contributions after the sale agreement is signed (but before the transfer date), employees lose benefit eligibility. This creates liability for both parties and can trigger ESIC inspection.
Mistake 4: Not mapping employees to the new employer code (slump sale). If employees are not mapped to the new employer code on the ESIC portal, their contributions cannot be deposited under the new registration. This creates a technical non-compliance even if the new employer is willing to pay.
Mistake 5: Ignoring the 50% wage rule under the new Labour Codes. After transfer, if the new employer restructures salary (changing allowance mix), the wage definition under Section 2(88) of the Code on Social Security may bring new employees into ESIC coverage - or change the contribution base for existing employees.

Penalties for Non-Compliance During Business Transfer
| Non-Compliance | Penalty | Section / Rule |
|---|---|---|
| Non-payment of contributions | Interest at 12% p.a. on unpaid amount; damages up to the unpaid amount; employer contribution cannot be recovered from employee | Section 39(5) / Section 85-B ESI Act |
| Non-registration of new establishment (within 15 days) | Penalty up to Rs 5,000; plus liability for unregistered period contributions | Section 85 ESI Act |
| Failure to file half-yearly return | Penalty up to Rs 5,000 per return; inspection trigger | Regulation 26 ESI General Regulations |
| Failure to maintain prescribed registers | Penalty up to Rs 5,000; deemed non-compliance during inspection | Section 85 ESI Act |
| Recovery as arrears of land revenue | ESIC can recover unpaid amounts as 'arrears of land revenue' - attachment of property, bank accounts | Section 45-C ESI Act |
| Imprisonment (wilful non-compliance) | Up to 1 year imprisonment + fine up to Rs 5,000 for first offence; up to 2 years for subsequent offences | Section 85 ESI Act |
How ESIC Transfer Connects with Other Compliance During Business Change
When a business changes hands, ESIC is one of multiple compliance areas that must be addressed simultaneously: (1) EPF transfer - similar principles apply under Section 17-B of the EPF Act; both ESIC and EPF must be transferred together, (2) income tax - the business transfer may trigger capital gains for the seller and carry-forward of losses for the buyer, (3) GST - the GST registration must be transferred or fresh registration obtained; ITC transfer depends on the type of sale (Section 18(3) CGST for change in constitution), (4) POSH Act compliance, (5) Shops & Establishment registration, and (6) contract labour compliance.
Professional due diligence covers all these areas together - not ESIC in isolation. For GST transfer during business change, see our GST compliance on business change (know more).
ESIC Due Diligence Checklist for Business Acquisition
- Is the establishment currently registered under ESIC? (Verify employer code on esic.gov.in)
- Are all monthly contributions paid up to date? (Request last 36 months of challan receipts)
- Are half-yearly returns (Form 01-RA) filed for all periods? (Request copies)
- Are there any pending inspection reports or show cause notices?
- Are there any disputed assessments or appeals at the ESI Court / ESIC?
- How many employees are covered? (Cross-check with payroll register)
- Are contract labour employees separately registered and contributions paid?
- Is the 50% wage rule being applied correctly under the Code on Social Security?
- Are there any employees with pending benefit claims (maternity, sickness, disability)?
- Has the establishment been subject to any recovery proceedings (Section 45-C)?
- Are the prescribed registers (Accident Register, Employee Register) maintained?
- What is the estimated ESIC liability if all arrears are quantified?
Key Takeaways
ESIC compliance can and does transfer when a business changes hands - the mechanism depends on the type of transfer. Share purchase: same entity, same registration, same liabilities continue. Slump sale/asset purchase: new registration required; Section 97 imposes joint liability for pre-transfer arrears.
Section 97 of the ESI Act makes the transferee jointly and severally liable for all ESIC amounts due up to the transfer date - regardless of what the sale agreement says. Pre-acquisition ESIC due diligence is not optional.
Employees do not lose ESI benefits during a business transfer. The 'once covered, always covered' rule, combined with IP number-linked contribution history, ensures uninterrupted coverage. The new employer must map employees to the new employer code and ensure no contribution gap.
The biggest financial risk is undisclosed ESIC arrears: unpaid contributions + 12% interest + damages + potential recovery as arrears of land revenue. Quantify this liability before completing any acquisition.
Under the Code on Social Security 2020, the wage definition change (Section 2(88) - 50% rule) may expand ESIC coverage post-transfer if the new employer restructures salaries differently. Factor this into post-acquisition payroll planning.
