Labour Codes 2026: The 50% Basic Wage Rule, Mandatory Offer Letters & What HR Must Update Now

The 4 Labour Codes: A Quick Primer

India consolidated 29 central labour laws into four codes. All four are in full enforcement from 1 April 2026:

• Code on Wages 2019 — Governs minimum wages, payment of wages, equal remuneration. Introduces the uniform definition of "wages" that drives the 50% rule.
• Industrial Relations Code 2020 — Covers trade unions, dispute resolution, and standing orders. Larger establishments must have published standing orders.
• Social Security Code 2020 — Merges PF, ESI, gratuity, maternity benefit, and other social security provisions into one framework.
• Occupational Safety, Health and Working Conditions Code 2020 (OSHWC) — Sets workplace safety standards and mandates appointment letters for all workers across all industries.

The 50% Basic Wage Rule Explained

The Code on Wages 2019 defines "wages" to include basic pay, dearness allowance (DA), and retaining allowance. The rule: Basic + DA + Retaining Allowance must be at least 50% of total CTC.

Many companies historically kept basic salaries low (30–35% of CTC) and loaded allowances to reduce PF and gratuity liability. This structure is no longer compliant.

Example: ₹12 Lakh CTC

The total CTC remains the same. But the split changes significantly — higher PF contributions for both employer and employee, and a higher gratuity base. Employees leaving after 5 years receive materially more gratuity.

Mandatory Offer Letters Under OSHWC

The OSHWC Code 2020 makes appointment letters (offer/employment letters) mandatory for all employees across all industries — not just factories, mines, or establishments above a headcount threshold. This is a significant expansion from the earlier Factories Act and Contract Labour Act scope.

What a compliant offer letter must now include:

• Designation and nature of work
• Place of work
• Date of joining
• Wage/salary structure (which must now reflect the 50% basic rule)
• Working hours, leave entitlements
• Terms of termination / notice period

Failure to issue compliant offer letters exposes employers to penalties under OSHWC. For any establishment already issuing offer letters, the salary structure in those letters must now be revised to comply with the 50% basic rule.

F&F Settlement: 48-Hour Requirement

Under the new codes, full and final settlement must be completed within 48 hours of an employee's last working day. This is a sharp departure from the informal 30–45 day practices that were common.

HR teams need F&F templates that can be generated quickly and accurately — with correct gratuity calculations on the new (higher) basic, leave encashment, and any notice period recovery.

5 HR Document Types to Update Immediately

• Offer / Appointment Letters — Update salary structure to reflect 50% basic. Mandatory for all new hires; re-issue or addendum for existing employees in some cases.
• Employment Contracts — Review wage definition, PF clause, gratuity clause.
• Payslip Templates — Heads must align with the new wage definition; allowances must not exceed 50% of total CTC in aggregate.
• Full & Final Settlement Templates — Must support 48-hour turnaround. Gratuity calculation must use the new basic salary basis.
• Increment / Appraisal Letters — Any letter revising salary must reflect the 50% basic rule in the revised structure.

Frequently Asked Questions

Does the 50% basic wage rule apply to all companies or only large ones?

The Code on Wages 2019 applies to all establishments — there is no minimum headcount threshold for the 50% basic wage rule. Startups, SMEs, and large corporates are all covered.

If an employee's take-home reduces due to higher PF deduction, do we need their consent?

Restructuring salary to comply with the Code on Wages — without changing total CTC — is a legal compliance obligation, not a unilateral pay cut. Best practice is to issue a revised salary structure letter explaining the change and its statutory basis. Some employers also offer a temporary CTC true-up to offset the PF impact, but this is not legally required.

What happens if we miss the 48-hour F&F deadline?

Delayed F&F settlement can attract penalties under the respective state rules implementing the Labour Codes. Beyond legal risk, it triggers grievances and can affect employer brand. The practical solution is to have pre-built F&F templates that can be generated within hours of an employee's last day — not manually assembled over weeks.
