The Ministry of Labour & Employment has issued an implementation notification (illustrative reference: S.O. 112(E)) confirming that the four consolidated Labour Codes — the Code on Wages 2019, the Industrial Relations Code 2020, the Code on Social Security 2020, and the Occupational Safety, Health and Working Conditions (OSH) Code 2020 — will be brought into force in a phased manner beginning 1 January 2026, subject to states finalising their respective draft rules.

For payroll teams, the most consequential change is the codified definition of 'wages' under Section 2(y) of the Code on Wages, which caps allowances, retirals and other exclusions at 50% of total remuneration. Any component structured to reduce basic pay below this threshold will need to be reworked, as the balance will be deemed 'wages' for the purposes of PF, gratuity, and statutory bonus computation.

Employers with cost-to-company structures that rely heavily on special allowances, LTA, or flexible benefit plans to optimise statutory contributions should expect a material increase in PF and gratuity liability once the wage definition takes effect, since basic-equivalent pay will rise as a proportion of CTC.

The Industrial Relations Code raises the threshold for mandatory standing orders to establishments employing 300 or more workers (up from 100 under the erstwhile Industrial Employment (Standing Orders) Act), and introduces a fixed-term employment category with parity of benefits for fixed-term employees vis-à-vis permanent workers on a pro-rata basis.

Under the Code on Social Security, the definition of 'employee' has been widened to explicitly capture gig and platform workers, with a proposed social security fund financed through a cess of 1-2% of annual turnover for aggregators, though the operative contribution mechanism is still pending final rules from several states.

The OSH Code consolidates 13 erstwhile labour statutes and introduces a single licence-cum-registration regime for establishments, along with an enhanced appointment letter mandate — every employer must now issue a formal appointment letter to every employee, including those engaged through contractors, within a prescribed format.

Given that implementation depends on concurrent notification of state-specific rules, employers should treat 1 January 2026 as an outer compliance horizon and begin remediation now: reviewing CTC structures, appointment letter templates, standing orders applicability, and contractor engagement models well ahead of the effective date in each state where they operate.
