Four Labour Codes Are Live: What the 50% Wage Rule Does to Your MSME Payroll
The four Labour Codes took effect on 21 November 2025, folding 29 laws into four. The 50% wage rule can lift PF and gratuity costs 5-15%. Here is how small businesses should restructure salaries, appointment letters and PF/ESI before the Central Rules finalise.
- The four Labour Codes became effective on 21 November 2025, consolidating 29 existing labour laws into four (PIB, 2025).
- The 50% wage rule — basic pay must be at least half of CTC — can raise PF and gratuity outgo by roughly 5-15% for most employers.
- Appointment letters are now mandatory for every worker, and fixed-term staff can claim gratuity after one year instead of five.
The four Labour Codes became effective on 21 November 2025, folding 29 existing central labour laws into four consolidated codes (PIB, 2025). For a small business, the political framing does not matter much. What matters is one practical shift: the way you structure salaries, PF, gratuity and appointment letters is changing, and it usually costs a little more.
The useful question is simple. If your basic pay is currently kept low to reduce PF, does the new "wages" definition force it up — and by how much? This guide turns the codes into a payroll-restructuring checklist you can act on before the Central Rules finalise.
What actually changed on 21 November 2025?
The government notified all four codes — the Code on Wages 2019, the Industrial Relations Code 2020, the Code on Social Security 2020 and the OSH and Working Conditions Code 2020 — as effective from 21 November 2025, rationalising 29 labour laws into one framework (PIB, 2025). Draft Central Rules were notified on 30 December 2025, with final rules targeted around 1 April 2026, so the structure is live even while some operational detail settles.
In plain terms: the law is in force, and you should assume the new rules apply to your next salary cycle. The transition period tidies up mechanics; it does not pause the codes.
If you are still running payroll informally, this is the moment to formalise. Start with clean books and a proper vendor and employee register — our finance and compliance services page covers the groundwork.
Why does the 50% wage rule cost more?
The codes use a single definition of "wages" (Section 2(y) of the Code on Wages) that requires basic pay to be at least 50% of total CTC, and this is estimated to raise statutory PF and gratuity costs by roughly 5-15% for most employers (TopSource Worldwide, 2026). PF and gratuity are computed on that wage base, so a bigger basic means bigger contributions.
Here is the mechanics. Many SMBs historically kept basic pay at 30-40% of CTC and loaded the rest into allowances, which shrank the PF base. Once basic must be at least half of CTC, the contribution base jumps — and take-home pay can dip slightly even when CTC is unchanged, because more is diverted into PF.
What new paperwork do small employers owe?
Mandatory appointment letters for every worker are now a headline obligation, and fixed-term employees can claim gratuity after one year of service instead of five (Bajaj Finserv, 2025). Workers above 40 are also entitled to a free annual health check-up. These apply broadly, so even micro employers must update onboarding.
Practically, build a simple template pack: an appointment letter stating wages and terms, a salary structure that respects the 50% rule, and a record of PF and ESI enrolment. Keep it standard across hires so an inspector — or a departing employee — sees consistency.
What happens to PF and ESI thresholds?
EPF continues to apply to establishments with 20 or more employees, and the ESI wage-coverage threshold of ₹21,000 a month continues during the transition, now computed on the new wages definition (DLA Piper, 2025). Establishments below the threshold can voluntarily opt in.
The direction of travel is wider coverage: social security reached over 64% of the workforce in 2025, up from about 19% in 2015, and the e-Shram portal has crossed 31 crore unorganised worker registrations (Upstox, 2025). For a growing firm, plan for formalisation, not around it.
Action plan for the next 30 days
Do not wait for the final rules. Week 1: audit every salary structure and flag any where basic pay is below 50% of CTC. Week 2: model the revised PF and gratuity cost so the number does not surprise you at payroll. Week 3: issue or refresh appointment letters. Week 4: reconcile PF and ESI enrolment and fix gaps.
If payroll and compliance are eating your week, hand the recurring parts to a professional and keep your focus on the business. Get your books and statutory filings in order first with bookkeeping and compliance support, then layer payroll on a clean base.
What to verify before acting on Four Labour Codes Are Live
Rules and platform behaviour change after an article is published. Confirm thresholds, registration status, return forms, document rules, and portal notices against the GST Portal before you act on anything below, because the right answer depends on your entity, state, turnover, and current setup.

Frequently asked questions
When did the four Labour Codes take effect?
The four Labour Codes — the Code on Wages 2019, the Industrial Relations Code 2020, the Code on Social Security 2020 and the OSH & Working Conditions Code 2020 — became effective on 21 November 2025, rationalising 29 earlier central labour laws. Draft Central Rules were notified on 30 December 2025, with final rules targeted around 1 April 2026, so the framework is live while some operational detail is still settling.
What is the 50% wage rule and why does it cost more?
The Codes use a single definition of "wages" (Section 2(y) of the Code on Wages) that requires basic pay to be at least 50% of total CTC. Because PF, gratuity and other statutory contributions are computed on that larger wage base, employers who earlier kept basic pay low see PF and gratuity costs rise by roughly 5-15%. Take-home pay can fall slightly even when CTC is unchanged.
Do small businesses have to give appointment letters now?
Yes. Mandatory appointment letters for all workers are one of the headline changes, giving workers a documented record of terms. Fixed-term employees can now claim gratuity after one year of service instead of five, and workers above 40 are entitled to a free annual health check-up. These apply broadly, so even micro employers should update their onboarding paperwork.
What happens to PF and ESI thresholds under the new codes?
EPF continues to apply to establishments with 20 or more employees, and the ESI wage-coverage threshold of ₹21,000 a month continues during the transition, now computed on the new "wages" definition. Social-security coverage of the workforce has already risen from about 19% in 2015 to over 64% in 2025, and establishments below the threshold can voluntarily opt in.
