ISMW License and Registration Consultant in Chennai and Across India — Inter-State Migrant Workmen Compliance Made Complete
Table of Contents
ToggleBusinesses that engage workers from other states — whether in construction, manufacturing, infrastructure, logistics, or any other labour-intensive sector — operate under one of India’s most specific and frequently overlooked labour laws. The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979 imposes clear, enforceable obligations on every principal employer and contractor who engages migrant workers from other states. The penalty for non-compliance is not a warning. It is prosecution — with imprisonment and fines applicable from the first violation.
Viriksha HR Solutions is a dedicated ISMW license consultant and ISMW registration consultant serving principal employers, contractors, construction companies, manufacturing businesses, infrastructure developers, and project-based organisations across Chennai, Tamil Nadu, and Pan India — managing every aspect of ISMW compliance from initial registration and licensing through to documentation, record maintenance, and inspection support.

The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979 is a central legislation enacted to regulate the employment of workers who are recruited in one state and employed in another. The Act recognises that inter-state migrant workers — who leave their home states for employment — are among the most vulnerable categories of workers in India, frequently exploited through wage suppression, non-payment of dues, denial of statutory benefits, and substandard living conditions.
The Act addresses this vulnerability by imposing specific obligations on both the principal employer and the contractor who recruits and deploys migrant workers — covering registration, licensing, wage protection, displacement allowance, journey allowance, suitable accommodation, and maintenance of prescribed records.
The Act applies to every establishment that employs five or more inter-state migrant workmen on any day of the preceding twelve months — either directly or through a contractor. It also applies to every contractor who recruits five or more inter-state migrant workmen for deployment at an establishment in another state.
The definition of inter-state migrant workmen is specific: a person who is recruited by or through a contractor in one state for employment in an establishment in another state. The key element is cross-state recruitment and deployment. A worker from Bihar employed at a construction site in Chennai through a contractor based in Bihar is an inter-state migrant workman under the Act — regardless of how long they have been in Tamil Nadu or whether they consider themselves a permanent resident.
The threshold of five workers is significantly lower than the thresholds under the Contract Labour Act or the BOCW Act — meaning many establishments that have complied with other labour laws have not considered their ISMW Act obligations.
Every principal employer of an establishment to which the ISMW Act applies must register the establishment with the registering officer — the Labour Commissioner or designated authority of the state in which the establishment is located.
ISMW registration must be obtained before inter-state migrant workers are employed at the establishment. Operating an establishment with inter-state migrant workers without registration is a direct violation of the Act — and carries penalties under Section 23 including imprisonment of up to one year, a fine of up to ₹1,000, or both.
The registration certificate issued to the principal employer must be maintained at the establishment and produced on demand by any inspector appointed under the Act.
Registration under the ISMW Act establishes the principal employer’s formal acknowledgement that inter-state migrant workers are employed at the establishment, creates the legal framework under which the principal employer’s obligations to those workers must be met, and triggers the inspection authority of ISMW Act inspectors to visit the establishment and verify compliance.

Every contractor who recruits inter-state migrant workmen — in the state of recruitment — must obtain a licence from the licensing authority of the state in which the establishment where the workers will be employed is located.
The ISMW contractor licence is separate from the principal employer’s registration. It is the contractor’s own authorisation to recruit and deploy inter-state migrant workers — and it must be obtained before recruitment begins, not after the workers arrive at the employment site.
The ISMW licence specifies the contractor’s name and address, the name and address of the principal employer, the nature and location of the work for which workers are being recruited, the maximum number of inter-state migrant workmen to be employed, the period of validity, and the conditions subject to which the licence is granted.
A contractor who recruits inter-state migrant workers without a valid ISMW licence is in violation of the Act — with the same penalty exposure as an unregistered principal employer. The principal employer who engages an unlicensed contractor carries additional exposure under the principal employer’s obligation to verify contractor compliance before engagement.
Beyond registration and licensing, the ISMW Act imposes substantive obligations on both principal employers and contractors that continue throughout the period of employment of migrant workers.
Every inter-state migrant workman is entitled to a displacement allowance equal to 50% of the monthly wages payable to the workman or ₹75, whichever is higher — paid at the time of recruitment in the home state, before the worker travels to the state of employment.
Every inter-state migrant workman is entitled to payment of journey allowance covering the cost of travel from the home state to the place of employment — paid by the contractor at the time of recruitment. Return journey allowance must be paid at the end of the period of employment.
The contractor is required to provide suitable residential accommodation to every inter-state migrant workman for the period of employment in the destination state.
Adequate medical facilities must be provided to inter-state migrant workmen at the place of employment — either through the contractor or through the principal employer's existing facilities.
Where the nature of work requires protective clothing — high-visibility vests, helmets, boots, gloves — the contractor must provide them to inter-state migrant workmen at no cost.
Inter-state migrant workmen performing the same or similar work as other workers at the establishment must receive wages at the same rate — no discrimination in wages on the basis of state of origin.
Wages of inter-state migrant workmen must be paid at a rate not less than the wages fixed under the Minimum Wages Act for the state of employment — not the state of recruitment. Where the minimum wage in the destination state is higher than in the home state, the higher rate applies.

ISMW compliance requires specific documentation at every stage — from initial registration and licensing through to ongoing record maintenance. This is the complete documentation procedure that every principal employer and contractor must follow.
Before applying for ISMW registration, the principal employer must prepare and compile the following documents:
Establishment documents: Certificate of incorporation or partnership deed or proprietorship declaration. PAN card of the establishment. GST registration certificate. Address proof of the establishment — electricity bill, lease agreement, or property tax receipt. List of directors or partners with identity proof.
Establishment details for the application: Name and complete address of the establishment. Nature of the business or construction activity. Total number of workers employed — including inter-state migrant workers. Names of states from which inter-state migrant workers are recruited. Name and designation of the principal employer — the person responsible for the establishment under the Act.
Supporting statutory documents: Existing labour law registrations — EPF code, ESIC code, Shops Act or Factories Act registration. Contract agreement or work order with the contractor engaging inter-state migrant workers. Proof of payment of applicable registration fee.
With documents compiled, the ISMW registration application is filed with the registering officer — typically the Assistant Labour Commissioner or Labour Commissioner of the state — in the prescribed Form I under the ISMW Act Rules.
Form I requires: Name and address of the principal employer. Name and address of the establishment. Nature of work carried out at the establishment. Maximum number of inter-state migrant workmen employed or to be employed on any day. States from which inter-state migrant workmen are recruited. Period for which registration is sought. Declaration by the principal employer regarding compliance with the Act’s obligations.
The application must be accompanied by the prescribed registration fee — calculated based on the number of inter-state migrant workmen employed. The fee varies by state and must be verified with the applicable state rules before filing.
Processing and issuance: After the application and fee are submitted, the registering officer reviews the application, may conduct a preliminary inspection of the establishment, and issues the registration certificate in Form II — typically within 30 to 60 working days depending on the state. The certificate specifies the registration number, the establishment details, the maximum number of migrant workers covered, and the period of validity.
Before applying for the ISMW contractor licence, the contractor must prepare:
Contractor identity and business documents: PAN card and Aadhaar of the contractor or authorised signatory. Certificate of registration of the contracting firm — incorporation certificate, partnership deed, or GST registration. Address proof of the contractor’s office — in the state of recruitment and in the state of employment. Bank account details of the contractor.
Work-related documents: Copy of the work order or contract agreement with the principal employer — specifying the nature of work, location, duration, and estimated number of workers. Copy of the principal employer’s ISMW registration certificate. Details of the state or states from which workers will be recruited. Details of the place of employment in the destination state.
Worker welfare documents: Proposed accommodation arrangement for migrant workers at the place of employment — lease agreement or facility confirmation. Medical facility arrangement details. Protective clothing provision plan for applicable work types.
Financial documents: Security deposit as prescribed by the state — typically calculated on a per-worker basis. Proof of financial capacity to pay displacement allowance and journey allowance before recruitment begins.
The contractor licence application is filed with the licensing authority of the state in which the establishment — the place of employment — is located, in the prescribed Form IV under the ISMW Act Rules.
Form IV requires: Name and address of the contractor. Name and address of the principal employer and the establishment. Nature and location of the work for which workers are to be recruited. States from which recruitment will be made. Maximum number of inter-state migrant workmen to be employed. Period for which the licence is sought. Details of accommodation, medical facilities, and protective clothing arrangements. Declaration regarding payment of displacement allowance and journey allowance.
The application must be accompanied by the prescribed licence fee — calculated on a per-worker basis — and the security deposit. The security deposit is refundable at the end of the licence period subject to compliance with all obligations under the Act.
Processing and issuance: The licensing authority reviews the application, verifies the contractor’s compliance capacity — accommodation arrangements, financial capacity for displacement and journey allowance — and issues the licence in Form V. The licence specifies the maximum number of workers, the states of recruitment, the period of validity, and the conditions of the licence.
ISMW compliance does not end with registration and licensing. Both principal employers and contractors must maintain specific registers and records throughout the period of employment of migrant workers.
Register of inter-state migrant workmen — Form IX (Contractor): Every contractor must maintain a register of inter-state migrant workmen in Form IX — capturing for every migrant worker: name, father’s or husband’s name, age, sex, home state address, date of recruitment, designation or nature of work, date of commencement of employment, wages paid, displacement allowance paid, journey allowance paid, period of employment, and date and reason of leaving.
This register must be maintained at the site of employment and produced on demand by any inspector under the Act. It is the primary record through which an inspector verifies that every migrant worker’s entitlements have been paid.
Register of contractors — Form XIII (Principal Employer): The principal employer must maintain a register of contractors in Form XIII — capturing for each contractor: name and address, nature of work, period of the contract, maximum number of migrant workers employed, and licence number of the contractor.
Muster roll and wage register: A muster roll recording daily attendance of inter-state migrant workmen and a wage register showing wages paid — consistent with the applicable minimum wage for the state of employment — must be maintained and made available for inspection.
Displacement allowance payment record: Written evidence that displacement allowance was paid to each migrant worker at the time of recruitment — signed acknowledgement from the worker, payment receipt, or bank transfer record — must be maintained by the contractor.
Journey allowance payment record: Written evidence of outward journey allowance paid at time of recruitment and return journey allowance paid at end of employment — for each migrant worker.
ISMW registration certificates and contractor licences are issued for a specified period — typically one year or for the duration of the project. Renewal must be obtained before the expiry date. Operating on an expired registration or licence is treated identically to operating without registration or a licence.
Where the number of migrant workers increases beyond the registered or licensed limit, or where the nature of work changes materially, an amendment application must be filed before the change takes effect.

In Tamil Nadu, the ISMW Act is administered by the Labour Department of the Government of Tamil Nadu. Registration and licensing applications are filed with the Assistant Labour Commissioner or Labour Commissioner of the relevant district.
Chennai’s construction, manufacturing, and infrastructure sectors employ significant numbers of inter-state migrant workers — primarily from Odisha, Bihar, West Bengal, Uttar Pradesh, and Rajasthan. Construction sites in and around Chennai, manufacturing plants in Ambattur, Sriperumbudur, and Oragadam, and infrastructure projects across Tamil Nadu engage inter-state migrant workers in substantial numbers — creating ISMW Act compliance obligations that many establishments have not formally addressed.
Labour inspections in Tamil Nadu under the ISMW Act verify registration and licence status, inspect the register of inter-state migrant workmen, confirm displacement allowance and journey allowance payment records, check accommodation arrangements, and verify wage payment at or above the Tamil Nadu minimum wage rate.
