The single labour return filing process under India’s Four Labour Codes is now the most critical employer compliance obligation of 2026. India has consolidated over 29 central labour laws into four comprehensive codes — and every employer, from a Jaipur-based manufacturer to a multinational corporation entering India via Rajasthan’s growing industrial corridors, must now file one unified annual return instead of dozens of fragmented submissions. This landmark reform affects payroll management, social security contributions, occupational safety reporting, and industrial relations compliance — all captured in a single digital filing on the Shram Suvidha Portal.
For Indian businesses and international clients unfamiliar with Indian labour law, this change represents both an opportunity and a legal minefield. Missing deadlines, misclassifying workers, or filing incomplete data can trigger penalties exceeding ₹2 lakh per violation. That is why Khanna & Associates — a trusted name in employment and corporate law — has created this definitive 2026 guide. Whether you operate in Jaipur, Dehradun, Mumbai, or are entering India from abroad, this step-by-step breakdown gives you complete compliance clarity.

What Is the Single Labour Return? — Complete Definition & Overview
Before the Four Labour Codes, Indian employers filed separate annual returns under each applicable parent law — the Factories Act, the Minimum Wages Act, the Payment of Wages Act, the Employees’ Provident Funds Act, the ESI Act, and more. For a mid-sized manufacturer, this meant managing up to 12–15 distinct compliance filings every year.
The Four Labour Codes introduced by the Government of India consolidate this entirely:
Code on Wages, 2019 — Minimum wages, payment of wages, bonus, and equal remuneration.
Industrial Relations Code, 2020 — Trade unions, industrial disputes, and standing orders.
Code on Social Security, 2020 — EPF, ESI, gratuity, maternity benefit, and gig worker welfare.
Occupational Safety, Health and Working Conditions Code (OSH Code), 2020 — Factory safety, health standards, and working conditions.
Under the new framework, employers file one combined annual return through the Shram Suvidha Portal (shramsuvidha.gov.in), using a unified form that covers all four codes. This is what is now universally referred to as the single labour return. For clients exploring Labour & Service Law support, this single return represents the centrepiece of your annual compliance calendar.
Legal Framework & Regulations Governing the Four Labour Codes
The statutory basis for single return filing is built on four sets of Central Rules, each notified between 2020 and 2021:
Code on Wages (Central) Rules, 2020
Industrial Relations Code (Central) Rules, 2021
Code on Social Security (Central) Rules, 2021
OSH Code (Central) Rules, 2020
These rules empower both the Central Government and State Governments to prescribe the unified return format. Corporate Compliance obligations attach from the moment an establishment crosses the applicable worker threshold — typically 10 or more workers, though this varies by code and state.
The Government has introduced the Labour Identification Number (LIN) to uniquely identify every registered employer in the digital ecosystem. Every establishment must obtain or update its LIN before filing. Failure to register correctly results in the return being flagged as non-compliant, regardless of the data accuracy inside it.

Step-by-Step: Single Labour Return Filing Process 2026
Step 1 — Register and Log In on the Shram Suvidha Portal
Visit shramsuvidha.gov.in and create your employer account. If your establishment was registered under the old system, migrate your existing data and update your LIN. Ensure the principal employer and every contractor establishment under you are separately registered.
Step 2 — Gather Compliance Data Across All Four Codes
Collect the following records for the preceding calendar year:
Wage registers, bonus payment records, overtime data (Code on Wages)
Trade union recognition status, industrial dispute records, standing orders compliance status (IR Code)
EPF and ESI monthly challans, gratuity and maternity benefit payments, ESIC coverage records (Social Security Code)
Accident register, health check-up records, factory license compliance, safety audit reports (OSH Code)
Step 3 — Complete the Unified Annual Return Form
The combined form captures:
Total workforce: regular, contractual, male, female, transgender workers
Maximum, minimum, and average wages paid
Working days, leave records, overtime details
Monthly social security contribution data
Number of occupational injuries, fatalities, and safety incidents
Status of standing orders and collective bargaining agreements (where applicable)
Step 4 — Upload Supporting Documents
Attach digitally signed copies of ESI/EPF challans, factory license, payroll summaries, accident reports, and maternity/gratuity payment proofs.
Step 5 — Submit Before the Statutory Deadline
The annual return under the Four Labour Codes must be filed by February 1, 2026 for the calendar year 2025. State-specific deadlines may differ — Rajasthan employers should verify the state notification currently in force.
Step 6 — Download and Retain Acknowledgment
Once submitted, download the portal-generated acknowledgment. Maintain all underlying records for a minimum of three years as mandated across all four codes.
This is precisely the end-to-end process that Khanna & Associates — a best law firm in Jaipur with national-level employment law expertise — manages for clients across industries, jurisdictions, and establishment sizes.
Key Legal Insights, Compliance Rules & Benefits
Applicability Thresholds: The four codes do not apply uniformly. The OSH Code applies to factories with 10 or more workers using power, or 20 or more without power. The Social Security Code extends ESI coverage to establishments with 10 or more employees. Understanding which code triggers which obligations is a nuanced legal exercise — not a checkbox activity.
Penalty Structure:
Code on Wages: ₹20,000 for first offence; ₹40,000 for second; up to ₹1 lakh for third and beyond.
OSH Code: Up to ₹2 lakh for serious safety violations; up to ₹3 lakh for fatal accident non-reporting.
Industrial Relations Code: Up to ₹1 lakh for illegal strike facilitation; up to ₹10 lakh for lock-out violations.
Real-World Example: A German automotive component manufacturer establishing a facility in Rajasthan through Foreign Direct Investment previously navigated 11 separate annual labour filings. Under the four codes, their annual compliance consolidates into one return — but the legal complexity of correctly computing wages under the new “inclusive wages” definition under the Code on Wages requires expert guidance to avoid underpayment claims.
Gig and Platform Worker Provisions: The Code on Social Security is the first Indian statute to formally recognise gig and platform workers. Aggregator companies — including food delivery, e-commerce logistics, and app-based service platforms — must now contribute to a Social Security Fund for these workers. This is a rapidly evolving compliance frontier.

Common Mistakes & Legal Challenges — Indian & International Clients
- Misclassifying Contract Workers
Treating contract labour as outside the scope of social security contributions is the single most common — and most costly — compliance error. The Code on Social Security significantly tightens contractor liability provisions. - Ignoring State-Level Notification Status
As of 2026, several states are still operating under transitional provisions. A business compliant with Central rules may unknowingly violate state-specific provisions. This is particularly relevant for multi-state businesses operating in Rajasthan, Delhi, and Uttarakhand (including Dehradun-based operations). - Incorrect Wage Definition
The Code on Wages redefines wages to include components previously excluded — such as special allowances. Many employers have not restructured their payroll accordingly, exposing themselves to minimum wage violation claims. - Delayed Standing Orders Certification
Under the old Industrial Disputes Act, standing orders were required for establishments with 100+ workers. The IR Code lowers this to 300+ workers — but several state governments retain the 100-worker threshold. Failure to certify standing orders attracts significant penalties. - LIN Non-Registration for New Businesses
Foreign companies and new Indian startups frequently begin operations without completing LIN registration — a foundational error that renders the annual return unfeasible.
As a top law firm in India and one of the best law firms in Jaipur, Khanna & Associates conducts pre-filing labour compliance audits to catch every one of these errors before they trigger enforcement action.
Expert Tips from Senior Advocates at Khanna & Associates
Meet our senior advocates — experienced legal professionals who bring decades of court-tested, field-tested expertise in Indian labour law, corporate compliance, and cross-border employment structuring.
Tip 1 — Audit Before You File
Never file the annual return without first conducting an internal payroll and compliance audit. Errors discovered after submission require rectification proceedings and draw regulatory scrutiny.
Tip 2 — Map State Notification Status Every Quarter
State governments are notifying and amending rules on a rolling basis. A quarterly legal update — which our team provides to retainer clients — ensures you always operate on the current applicable rules, not outdated central templates.
Tip 3 — Restructure Wage Components Now
The inclusive definition of wages under the Code on Wages has direct implications for PF contributions, gratuity computation, and bonus eligibility. Restructuring wage components to be legally compliant — without inflating costs — requires careful legal and financial planning.
Tip 4 — Engage Legal Counsel at Business Setup, Not at Crisis
International companies expanding into India through our Company Formation & Business Setup service benefit from compliance frameworks built into the foundation of their Indian entity — not retrofitted after a labour department notice arrives.
Tip 5 — Document Gig Worker Arrangements Formally
If your business model involves gig or platform workers, formalise those arrangements with compliant agreements through our Agreement Lawyers before the Social Security Fund contribution rules are fully enforced.
Tip 6 — Use Arbitration Clauses in Employment Agreements
Under the IR Code, certain industrial disputes are arbitrable. Including well-drafted arbitration clauses in employment contracts — reviewed by our Arbitration and Reconciliation team — significantly reduces litigation risk and resolution timelines.

─── FAQ SECTION ───
FAQ 1: What exactly is the Single Labour Return under the Four Labour Codes, and who must file it?
The Single Labour Return is a unified annual compliance filing that consolidates data required under all four Labour Codes — Code on Wages, Industrial Relations Code, Social Security Code, and OSH Code — into one digital submission on the Shram Suvidha Portal. Every employer covered under one or more of the four codes, based on applicable workforce thresholds, must file this return annually. It replaces over a dozen separate filings required under the old labour law framework.
FAQ 2: What is the deadline for filing the Single Annual Return under the Four Labour Codes in 2026?
The statutory deadline for filing the annual return under the Four Labour Codes is generally February 1, 2026, covering the preceding calendar year (January–December 2025). However, state governments may prescribe different deadlines in their own notified rules. Employers operating across multiple states should verify each state’s applicable deadline to avoid penalties for late filing under the new unified labour compliance framework.
FAQ 3: What penalties apply if an employer fails to file the Single Labour Return on time in India?
Penalties vary by code. Under the Code on Wages, a first-time non-filing offence attracts a fine of up to ₹20,000, escalating to ₹40,000 for repeat violations. The OSH Code imposes penalties up to ₹2 lakh for safety violations and up to ₹3 lakh if a fatality goes unreported. Repeat non-compliance can also result in cancellation of factory licences and registration certificates, making timely labour code compliance filing non-negotiable.
FAQ 4: Can foreign companies or NRI-owned businesses in India file the Single Labour Return themselves, or do they need a local lawyer?
While the Shram Suvidha Portal is technically accessible to any registered employer, foreign companies and NRI-owned businesses are strongly advised to engage a qualified Indian labour law attorney for the filing process. The inclusive wage definition, gig worker provisions, and state-level rule variations create significant legal complexity. Incorrect filings expose foreign entities to back-dated penalty claims and regulatory scrutiny. Expert guidance from an experienced law firm ensures full compliance from day one.
FAQ 5: How does the Four Labour Codes reform benefit employers compared to the old labour law compliance system?
The Four Labour Codes consolidate 29+ central labour laws into four comprehensive statutes, reducing employers’ annual compliance burden by up to 70%. Instead of filing 10–15 separate returns under different parent laws, employers now file one unified annual return. The Shram Suvidha Portal provides a single digital interface, a compliance calendar, and automated reminders. For growing businesses and foreign investors, this reform significantly reduces administrative costs and the risk of inadvertent non-compliance under any of the previously scattered labour statutes.
