What a principal employer files, and when

A registration kept current, a notice when contract work starts or stops, and an annual return listing every contractor. The dates, and the data needed.

Tall stacks of old paper files and registers, each bundle tied with thin blue string, filling a records room from edge to edge.

Three things, on top of what the contractor files. A registration under section 3 of the OSH Code 2020, updated within 30 days of any change. A notice within 30 days of starting or stopping operations that involve contract labour. And an annual return that lists every contractor, month by month, with its headcount and the wage bills paid. Most of the data in that return sits with the contractor, so the site has to collect it all year.

Registration, and keeping it current

Every establishment the Code covers registers once, electronically, and updates the registration whenever its particulars change. Section 3(1) gives a new establishment 60 days from the date the Code applies to it. One already registered under an earlier Central labour law is deemed registered under section 3(8), but has to supply its details: rule 3(6) of the OSH (Central) Rules 2026 gives it six months from 8 May 2026, the date the rules came into force, to update its particulars in Form I.

The certificate the site receives, Form III under the Central rules, records the number of workers engaged through contractors and the number and details of the contractors. Section 3(4) and rule 3(8) require any change in the Form I particulars to be updated on the portal within 30 days [VERIFY: whether every change in contract headcount triggers an update, or only a new or departing contractor]. Section 3(7) bars an establishment that has not registered from employing anyone.

Which column applies depends on the appropriate government. A private factory or warehouse in Tamil Nadu follows the State's rules, still in draft from April 2022 [VERIFY: whether Tamil Nadu's final OSH rules keep these provisions].

A notice when contract work starts or stops

Within 30 days, electronically. Section 5 of the Code requires the employer of an establishment "relating to contract labour" to give notice of commencement and cessation of operations. Rule 4 of the Central rules prescribes Form VI, sent to both the registering officer and the Inspector-cum-Facilitator; rule 5 of the Tamil Nadu draft prescribes Form II. A cessation notice carries a certificate that all dues to the workers have been paid and the premises are free of stored hazardous chemicals.

The Code does not say when an existing site becomes an establishment relating to contract labour, for instance on the day its first contractor starts. That is a question for the site's own counsel; a site that files the notice when it first brings in contract labour has a record either way.

The annual return

One return a year, for the calendar year, and the contract-labour part is the heaviest. Under the Central rules it is Form XVII, due by the last day of February (r.72(5) and r.74). Part I covers every establishment: headcount split between direct and contractor-engaged workers by skill and gender, a list of contractors with their Labour Identification Numbers and contract headcount, welfare amenities, industrial relations, bonus, maternity and accidents. Part III, under rule 98(9), is the principal employer's own return on Shram Suvidha.

Form XVII Part III asks, for each month and each contractorWhere the site gets it
Name, address and LIN of the contractorThe contractor's licence and registration
Name of the workThe work order
Maximum number of contract labour employedThe contractor's muster roll, checked against the gate register
Amount paid against the wage bill, including EPF, ESIC and bonus, and the dateThe site's own accounts payable
Wages paid directly by the principal employer when the contractor failed to pay, and the dateThe site's own payment records, if it ever had to step in

Tamil Nadu's draft replaces this with a single Form IX covering all four Labour Codes, due by 31 January and filed on the DISH or Labour Department portal with a copy to the Labour Bureau (r.35). Its contractor section asks for each contractor's name, address and licence number, the period and nature of the contract, days worked, man-days and the maximum number of workers employed.

What the contractor has to give the site

Most of the return comes from the contractor's records, so the site should collect them monthly, not in January.

  • Licence and LIN, before the first shift. Section 54 treats engaging a contractor that needs a licence and does not have one as a contravention of the Code.
  • The work-order intimation. Rule 94 of the Central rules requires the contractor to report each work order on Shram Suvidha within 15 days of receiving it, naming the principal employer, the premises, the start date, the headcount and the duration.
  • Monthly maximum headcount. From the contractor's muster roll, reconciled with the gate register, because Part III and Form IX both ask for the peak.
  • Wage-bill invoices with the statutory components shown. Part III asks for the amount paid including EPF, ESIC and bonus, so an invoice that bundles them into one rate leaves the site unable to fill the column.
  • The half-yearly return. Rule 98(7) requires the contractor to file Form XVIII within 30 days of each half-year closing; a copy belongs in the site's file.

Failing to file a return or maintain a register carries a penalty of ₹50,000 to ₹1 lakh under section 96(1) of the Code, and ₹50,000 to ₹2 lakh for a repeat. Other contraventions by an employer or principal employer fall under the general penalty in section 94: ₹2 lakh to ₹3 lakh, and up to ₹2,000 a day if the contravention continues after conviction. Records are kept for five years under the Central rules (r.72(1)(vii)) and three under Tamil Nadu's draft (r.33(4)). Which filings a particular site owes, and under whose rules, is for its own counsel to confirm.

Frequently asked questions

Does a principal employer need its own registration under the OSH Code?

Yes. Section 3 of the OSH Code 2020 requires every establishment the Code covers to register electronically, and the certificate records the workers engaged through contractors and the contractors themselves. A new establishment applies within 60 days; one registered under an earlier Central labour law is deemed registered but must update its details, within six months of 8 May 2026 under the Central rules.

When is the annual return due for a site that uses contract labour?

Under the OSH (Central) Rules 2026, Form XVII is due by the last day of February for the previous calendar year, and Part III is the principal employer's return on contractors. Tamil Nadu's 2022 draft rules use a unified Form IX across the four Labour Codes, due by 31 January. Which applies depends on whether the Central or State Government is the appropriate government.

What contractor details go into the principal employer's annual return?

Form XVII Part III under the Central rules asks, month by month for each contractor, for its name, address and Labour Identification Number, the work, the maximum contract labour employed, the amount paid against the wage bill including EPF, ESIC and bonus, and any wages the principal employer paid directly because the contractor did not.

What is the penalty for not filing an OSH Code return?

Section 96(1) of the OSH Code 2020 sets a penalty of ₹50,000 to ₹1 lakh for failing to file a return or maintain a register, and ₹50,000 to ₹2 lakh for a repeat. Other contraventions fall under section 94, at ₹2 lakh to ₹3 lakh, with up to ₹2,000 a day if the contravention continues after conviction.
