Contract Labour Regulations in India: CLRA Act, Compliance & Principal Employer Duties
Applicability & Key Definitions
The Contract Labour (Regulation & Abolition) Act, 1970 (CLRA Act) was enacted to regulate the conditions of service of contract labourers and prevent their exploitation, while also providing a mechanism for the appropriate government to abolish contract labour in certain processes where it is deemed perennial and not genuinely of a seasonal or intermittent nature.
Applicability Thresholds
| Entity | Applicability Threshold | Obligation |
|---|---|---|
| Principal Employer (Establishment) | 20 or more contract workmen employed on any day in the preceding 12 months | Register the establishment under the Act (Form I) |
| Contractor | Employs 20 or more workmen in connection with the work of a principal employer | Obtain a Licence from the licensing officer (Form IV) |
The threshold is 20 workmen for both categories. Some states have reduced this threshold via state rules (e.g., Maharashtra reduced the contractor threshold to 10 workmen). Once an establishment is covered, the Act continues to apply even if the number of workmen subsequently falls below the threshold.
Key Definitions under the CLRA Act
- Contract Labour (Section 2(b)): A workman who is hired in or in connection with the work of an establishment through a contractor, with or without the knowledge of the principal employer. The workman remains on the contractor's rolls, not the principal employer's.
- Contractor (Section 2(c)): A person who undertakes to produce a given result for the establishment other than a mere supply of goods, through contract labour; or who supplies contract labour for work of the establishment and includes a sub-contractor.
- Principal Employer (Section 2(g)): In relation to any office or department of the Government or a local authority, the head of that office; in a factory, the owner or occupier of the factory or the person named as manager under the Factories Act; in any other establishment, the person responsible for supervision and control.
- Workman (Section 2(i)): Any person employed in or in connection with the work of any establishment to do any skilled, semi-skilled or unskilled work, manual, supervisory, technical or clerical work. Excludes persons in a managerial, administrative or supervisory capacity earning more than ₹10,000 per month (under legacy Act; thresholds updated under Labour Codes).
- Appropriate Government: Central Government for central government establishments and certain specified industries (railways, mines, oilfields); State Government for all other establishments.
Registration vs Licensing: Form I and Form IV
The CLRA Act creates two distinct but complementary requirements:
Principal Employer Registration — Form I
Every principal employer of an establishment to which the Act applies must obtain a Certificate of Registration by applying in Form I to the Registering Officer (typically the Labour Commissioner or Deputy Labour Commissioner).
- Application timing: Before engaging contract labour in the establishment.
- Form I contents: Name and address of establishment, nature of work, particulars of the proposed contract labour engagement, estimated number of contract workmen, name of the manager/occupier.
- Registration fee: Prescribed by state rules based on the number of contract workmen.
- Consequence of non-registration: The establishment is prohibited from engaging contract labour. Each day of engagement without registration is a separate offence.
Contractor Licence — Form IV
Every contractor who employs 20 or more workmen must obtain a Licence from the Licensing Officer by applying in Form IV.
- Application timing: At least 30 days before commencement of the work for which contract labour is to be supplied.
- Form IV contents: Particulars of the contractor, details of the principal employer's establishment, nature of the work, maximum number of workmen to be employed, conditions of work.
- Security deposit: Contractors must deposit a security amount (typically ₹100 per workman up to a prescribed maximum) as a guarantee for payment of wages.
- Validity: Licence is valid for one year and must be renewed before expiry.
- Licence conditions: The licence specifies the maximum number of workmen, wages payable, and other conditions. Violations of licence conditions constitute a separate offence.
| Parameter | Principal Employer (Form I) | Contractor (Form IV) |
|---|---|---|
| Document obtained | Certificate of Registration | Licence |
| Filing party | Principal Employer | Contractor |
| Filed with | Registering Officer | Licensing Officer |
| Validity | Permanent (unless revoked) | Annual (renewal required) |
| Consequence of default | Prohibition on using contract labour | Prohibition on supplying contract labour; cancellation risk |
Prohibited Activities for Contract Labour
Under Section 10 of the CLRA Act, the Appropriate Government may by notification prohibit the employment of contract labour in any process, operation or other work in any establishment. Criteria for prohibition include:
- The work is of a perennial nature (not seasonal, intermittent or merely incidental).
- The work is done in establishments where regular workmen are employed for the same or similar work.
- Sufficient regular workmen are available in the concerned industry for the work.
Once contract labour is prohibited in a specific activity, the workmen performing that activity must be absorbed as direct employees of the principal employer — this has been the subject of extensive Supreme Court litigation (see section on court cases below).
Welfare Facilities & Wage Payment Obligations
Welfare Facilities — Contractor's Duty, Principal Employer's Backstop
The CLRA Act requires contractors to provide specified welfare facilities to contract workers (Sections 16-19). If the contractor fails to provide these, the principal employer is obligated to provide them and recover the cost from the contractor:
| Facility | Requirement | Threshold |
|---|---|---|
| Canteen | Wholesome meals at reasonable rates | 100 or more contract workmen; ordinarily for 6 months or more |
| Rest rooms / Temporary accommodation | Suitable accommodation for rest during intervals | Contract workmen required to halt at night at the place of work |
| Drinking water | Adequate clean drinking water at convenient points | All contract labour establishments |
| Latrines and urinals | Sufficient number; separate for men and women | All contract labour establishments |
| Washing facilities | Adequate washing and bathing facilities | All contract labour establishments |
| First aid | First aid box with prescribed contents; one per 150 workmen | All contract labour establishments |
Payment of Wages — Contractor Liability and Principal Employer Backstop
Under Section 21 of the CLRA Act:
- The contractor is primarily responsible for paying wages to contract workmen within the prescribed wage period.
- The principal employer must nominate a representative to be present at the time of wage disbursement by the contractor, who must certify that the disbursement was made correctly.
- If the contractor fails to pay wages within the prescribed period, the principal employer becomes directly liable to pay those wages and can recover the amount from the contractor as a debt.
- Wages paid to contract workers cannot be less than the applicable minimum wage for the category of work performed.
Registers, Forms & Annual Returns
Maintenance of prescribed registers and timely filing of returns is a critical compliance requirement under the CLRA Act and Central Rules, 1971:
Registers to be Maintained
| Form | Register Name | Maintained By | Key Contents |
|---|---|---|---|
| Form XII | Register of Contractors | Principal Employer | Name and address of contractor, nature of work, number of workmen deployed, period of contract |
| Form XIII | Register of Workmen employed by Contractor | Contractor | Name, father's name, age, sex, permanent address, nature of work, date of joining and leaving |
| Form XIV | Employment Card | Contractor (issued to each workman) | Employer details, nature of work, wages, leave entitlement — must be issued within 3 days of employment |
| Form XV | Service Certificate | Contractor | Certificate issued on termination of employment with details of service rendered |
| Form XVI | Muster Roll | Contractor | Daily attendance of each workman; must be maintained at the workplace |
| Form XVII | Register of Wages | Contractor | Wages paid, deductions, net amount paid, signature/thumb impression of workman |
| Form XIX | Wage Slip | Contractor | Issued to each workman at least a day before wages are paid; shows wage components and deductions |
Returns
- Form XXV (Annual Return by Contractor): Filed by the contractor with the Licensing Officer by February 15 for the preceding calendar year. Contains details of workmen employed, wages paid, welfare facilities provided.
- Form XXVI (Annual Return by Principal Employer): Filed by the principal employer with the Registering Officer by February 15 for the preceding calendar year. Contains details of contractors engaged, number of contract workmen deployed through each contractor.
EPF & ESI Applicability to Contract Workers
Contract workers are not exempt from social security coverage simply because they work through a contractor. The applicability of EPF and ESI to contract workers is one of the most litigation-heavy areas of Indian labour law compliance.
EPF (Employees' Provident Fund Act, 1952)
- If the contractor's establishment employs 20 or more persons (including contract workmen), EPF coverage is mandatory for all eligible employees of the contractor earning up to ₹15,000 basic per month.
- The contractor must obtain a separate EPF code and make contributions. The contractor must furnish a copy of the EPF challan to the principal employer each month.
- If the contractor defaults on EPF contributions, the principal employer is jointly and severally liable under Section 8A of the EPF Act, read with the CLRA Act. EPFO has the authority to recover dues directly from the principal employer.
- In practice, many principal employers insist on receiving monthly EPF/ESI challans from contractors as a condition of releasing vendor invoices — a commercially prudent practice that also limits legal exposure.
ESI (Employees' State Insurance Act, 1948)
- Contract workers earning up to ₹21,000 per month (₹25,000 for persons with disability) are covered under ESI in ESI-applicable areas.
- The contractor must register the contract workmen under ESI and remit contributions (employer: 3.25%, employee: 0.75% of wages).
- If the contractor fails to register or contribute, the principal employer is liable for the ESI contributions and any resulting penalties under Section 45A of the ESI Act.
- ESIC regularly conducts inspections at principal employer premises to verify contractor compliance — principals who cannot produce contractor ESI challans face direct recovery proceedings.
Penalties, Inspection Regime & Court Cases on Sham Contracting
Penalties under the CLRA Act
| Offence | Penalty |
|---|---|
| Engaging contract labour without registration (principal employer) | Imprisonment up to 3 months, or fine up to ₹1,000, or both |
| Deploying contract labour without licence (contractor) | Imprisonment up to 3 months, or fine up to ₹1,000, or both |
| Violation of licence conditions | Cancellation or suspension of licence + fine |
| Failure to maintain registers or file returns | Fine up to ₹500 per violation; continuing default — fine ₹100 per day |
| Failure to provide welfare facilities | Fine up to ₹500; recoverable costs from contractor by principal employer |
Inspection Regime
The CLRA Act provides for a layered inspection regime. Inspectors appointed by the Appropriate Government (both Central and State) are empowered to enter any premises where contract labour is employed, examine registers and records, examine workmen and contractors, and issue notices for non-compliance. Inspectors can be appointed by both the Central and State Governments, creating overlapping jurisdiction for establishments covered by Central and State rules simultaneously.
Abolition of Contract Labour
Under Section 10, the Appropriate Government can issue a notification prohibiting contract labour in any process or operation. This has been a contentious provision — industries have challenged abolition notifications arguing they harm competitiveness. The government must follow due process including consulting the Central Advisory Contract Labour Board before issuing abolition notifications.
Key Supreme Court Judgments on Sham Contracting
Indian courts have developed a robust body of jurisprudence to identify and penalise "sham contracting" — where a principal employer uses a contractor merely as a facade to deny workers direct employment status and statutory benefits:
- Steel Authority of India Ltd. v. National Union Water Front Workers (2001): The Supreme Court held that when contract labour is abolished under Section 10, the abolished contract workers do NOT automatically become direct employees of the principal employer. Direct absorption requires a specific government direction. This landmark judgment overturned earlier High Court decisions that had ordered automatic absorption.
- Bharti Airtel Ltd. v. A.S. Raghavendra & Others (2016): Supreme Court reiterated that courts cannot order absorption of contract labour merely because the work is perennial — abolition and absorption must follow the statutory process under Sections 10 and 10(2) respectively.
- Indicators of sham contracting identified by courts: Principal employer supervises the work directly; contractor has no independent workforce; contractor has no independent organisational structure; contractor does not bear financial risk; principal employer decides wage revisions.
- Consequence of sham contracting finding: Workers treated as direct employees of the principal employer for all purposes including EPF, ESI, Gratuity and regularisation.
Labour Code Changes: Social Security Code 2020
When implemented, the Code on Social Security 2020 and the Occupational Safety, Health and Working Conditions Code 2020 will substantially change the contract labour regulatory landscape:
- CLRA provisions absorbed into OHS Code: The OHS Code 2020 subsumes the CLRA Act. Core obligations (registration, licensing, welfare facilities) are retained but consolidated.
- Gig and platform workers: The Social Security Code extends coverage to gig and platform workers — persons engaged through aggregator platforms (e.g., delivery, cab services) — who currently fall outside any statutory framework.
- Universal Account Number (UAN): Social security portability enhanced; workers changing contractors retain their UAN and accumulated PF credits.
- Fixed-term workers: Fixed-term workers engaged through contractors will be entitled to all benefits proportionate to their term, including gratuity on a pro-rata basis without the 5-year vesting requirement.
- Threshold changes: Some states may revise the 20-workmen threshold when framing state rules under the new Codes.

Meghna Srivastava, CA Final student, Pune — Meghna was on an articleship assignment conducting a due diligence for a manufacturing company acquisition. While reviewing the target's labour compliance, she discovered that the company engaged 340 contract workers through five contractors — but had never obtained the Form I Certificate of Registration under the CLRA Act, and three of the five contractors had expired licences. More critically, she identified that one contractor had not deposited ESI contributions for 18 months, creating an undisclosed contingent liability of approximately ₹12 lakh that would become the principal employer's liability upon acquisition. The finding materially impacted the deal valuation and was reflected in the final Share Purchase Agreement escrow. Meghna's CorpReady module on contract labour had specifically covered the principal employer's deemed liability for contractor defaults — knowledge that directly shaped the deal outcome.
💼 What Firms Actually Want
Corporate legal and compliance teams, Big 4 transaction advisory teams, and in-house finance departments at large manufacturing and infrastructure companies are looking for professionals who understand that contract labour compliance is not just an HR problem — it is a balance sheet risk. Every contractor default on wages, EPF or ESI creates a contingent liability that sits on the principal employer's books. Candidates who can identify CLRA registration gaps during due diligence, quantify undisclosed ESI/EPF exposures, structure vendor contracts with enforceable compliance obligations (challan-linked payment clauses), and advise on the difference between genuine contracting and sham contracting under Supreme Court precedent are uniquely valuable at the intersection of law, finance and operations.
Frequently Asked Questions
The CLRA Act applies to every establishment that employs 20 or more contract workmen on any day in the preceding 12 months, and to every contractor who employs 20 or more workmen. The principal employer must register the establishment under the Act before engaging contract labour, and the contractor must obtain a licence before deploying workmen. Some states have reduced the threshold to 10 workmen. Establishments engaged in work of an intermittent or casual nature may seek exemption from the appropriate government.
Under Section 21(4) of the CLRA Act, if the contractor fails to pay wages to contract workers within the prescribed wage period, the principal employer is directly liable to pay those wages. The principal employer can then recover the amount paid from the contractor as a debt. This subsidiary liability of the principal employer is one of the most significant compliance risks in contract labour arrangements and is why large companies require contractors to submit signed wage disbursement registers before releasing invoices.
Yes. Contract workers are entitled to EPF and ESI coverage if they meet the respective thresholds. For EPF, if the contractor's establishment employs 20 or more employees, EPF coverage is mandatory. For ESI, workers earning up to ₹21,000 per month are covered. The contractor is primarily responsible for contributions. However, if the contractor defaults, the principal employer becomes jointly and severally liable under the EPF Act and ESI Act respectively. EPFO and ESIC can and do issue recovery notices directly to principal employers for contractor defaults.
Under the CLRA Act and Central Rules 1971, the principal employer must maintain a Register of Contractors (Form XII) showing details of all contractors engaged, number of workmen deployed and nature of work. The contractor must maintain the Register of Workmen Employed (Form XIII), Employment Cards (Form XIV) issued to each worker, Muster Roll (Form XVI), Register of Wages (Form XVII), and Wage Slips (Form XIX). Annual returns must be filed — Form XXV by the contractor and Form XXVI by the principal employer — both by February 15 for the preceding calendar year.
✅ Key Takeaways
- The CLRA Act applies when 20 or more contract workmen are employed; the principal employer must register (Form I) and contractors must obtain annual licences (Form IV) before deployment.
- The principal employer has a statutory backstop liability for wages, welfare facilities, EPF and ESI if the contractor defaults — this is not optional and creates quantifiable balance sheet risk.
- Seven key contractor registers (Forms XII to XIX) must be maintained and available for inspection; annual returns (Forms XXV & XXVI) are due by February 15 each year.
- EPF and ESI apply to contract workers; contractor defaults make the principal employer jointly and severally liable under both Acts — monthly challan collection is a critical control.
- Supreme Court precedents (Steel Authority of India, 2001) have established that abolished contract labour does not automatically become direct employees — formal government direction is required for absorption.
- The OHS Code 2020 subsumes the CLRA Act when implemented; the Social Security Code 2020 extends coverage to gig and platform workers and provides gratuity pro-rata for fixed-term workers.
