The four Labour Codes were notified as effective on November 21, 2025. The substantive provisions are now in force across India, although central rules under the Code on Wages were finalised around April 2026 and state-level rules vary in implementation timeline.
For employers, the most consequential change is the new statutory wage definition: Basic Pay + Dearness Allowance + Retaining Allowance must form at least 50% of total remuneration. This affects PF, gratuity, leave encashment, and bonus computation.
This guide is a practical implementation playbook for HR and finance teams in Indian SMEs.
What's Changed: A Quick Summary
The four Codes consolidate 29 earlier central labour laws:
- Code on Wages, 2019 (subsumes Payment of Wages Act, Minimum Wages Act, Payment of Bonus Act, Equal Remuneration Act)
- Industrial Relations Code, 2020 (subsumes Industrial Disputes Act, Trade Unions Act, Industrial Employment Standing Orders Act)
- Code on Social Security, 2020 (subsumes EPF Act, ESIC Act, Maternity Benefit Act, Payment of Gratuity Act, Building and Other Construction Workers Act, Unorganised Workers Act)
- Occupational Safety, Health and Working Conditions Code, 2020 (subsumes Factories Act, Plantations Labour Act, Mines Act, Contract Labour Act, Inter-State Migrant Workmen Act, etc.)
The headline change for most employers: the new uniform definition of "wages" under the Code on Wages, and how it cascades into social security and gratuity computations.
The 50% Basic + DA Rule: What It Actually Says
Under the Code on Wages, "wages" means the total remuneration paid to an employee, excluding specific allowances listed in the definition. However, the law caps the excluded allowances at 50% of the total remuneration. If allowances exceed 50%, the excess is automatically added back to "wages" for statutory calculations.
In practical terms: Basic + DA + Retaining Allowance must be at least 50% of total remuneration. If your salary structure has lower Basic, the law treats the excess allowance as if it were Basic for PF, gratuity, bonus, and leave encashment purposes.
Step-by-Step Implementation for Employers
Step 1: Map Your Current CTC Structure
For every employee, list out the CTC components:
- Basic Pay
- Dearness Allowance (DA), if any
- House Rent Allowance (HRA)
- Conveyance Allowance
- Special Allowance (often the largest line)
- Medical Allowance
- LTA
- Performance Bonus / Variable Pay
- Employer PF
- Employer ESI
- Gratuity provision
- Other allowances (mobile, internet, food, etc.)
Step 2: Compute Basic + DA as a Percentage of Total Remuneration
Total remuneration excludes employer's PF, employer's ESI, gratuity provision, and one-time payments.
Formula:
Wage Definition Basic = Basic + DA + Retaining Allowance
Total Remuneration = Sum of all monthly recurring components (excluding employer PF/ESI/gratuity)
Ratio = Wage Definition Basic / Total Remuneration
If Ratio < 50%, you need to restructure.
Step 3: Restructure Below-Threshold Salary Structures
Two common approaches:
Approach A: Increase Basic, reduce Special Allowance
- Push Basic + DA up to at least 50% of monthly recurring CTC
- Reduce Special Allowance correspondingly to keep gross unchanged
- Effect: PF, gratuity, and leave encashment liability rise; net take-home for the employee falls (because PF deduction is on a higher base)
Approach B: Recategorise Allowances
- Consolidate small allowances (medical, conveyance, food) into Special Allowance
- Then increase Basic at the cost of Special Allowance to hit 50%
- Effect: similar to Approach A but cleaner administrative structure
Step 4: Recompute PF Contributions
The PF base remains Basic + DA, capped at Rs 15,000 per month for mandatory coverage.
- Employee contribution: 12% of Basic + DA
- Employer contribution: 12% of Basic + DA (split between EPF and EPS)
After restructuring, the new Basic + DA might exceed Rs 15,000 for many employees. Those who were earlier above Rs 15,000 with voluntary higher contribution: their structure remains unchanged. Those at the boundary may now mandatorily come under PF.
Action:
- Run the new Basic + DA against the Rs 15,000 ceiling
- Check whether voluntary higher contribution consent is on file (for above-Rs-15,000 employees)
- Update PF challan generation in your payroll software
Step 5: Recompute Gratuity Liability
Gratuity formula: 15 days of last drawn salary for every completed year of service, capped at Rs 20 lakh tax-exempt.
"Last drawn salary" under the Code on Wages = Basic + DA + Retaining Allowance.
Effect of restructuring:
- Higher Basic = higher gratuity liability
- Run an actuarial revaluation of accrued gratuity for employees with 5+ years of service
- Provision the difference in your books
Step 6: Update Bonus Computation
Under the Payment of Bonus Act (now subsumed in the Code on Wages), bonus is payable to employees with wages up to Rs 21,000 per month, calculated on Rs 7,000 or the actual wages (whichever is lower).
The "wage" base now uses the Code on Wages definition. Run a recheck for everyone earning wages up to Rs 21,000.
Step 7: Update Leave Encashment Provisions
Leave encashment is paid at last drawn Basic + DA. Restructured Basic increases the leave encashment cost at separation. Provision accordingly.
Step 8: Update HRA Exemption Logic in Payroll
For FY 2026-27 onwards, Hyderabad, Bengaluru, Pune, and Ahmedabad also qualify for the 50% HRA exemption under the income tax framework, alongside Mumbai, Delhi, Kolkata, and Chennai.
This is a separate change (income tax, not labour code) but affects the same payroll cycle:
- Update HRA exemption logic in payroll software
- Communicate the change to employees in the four newly added cities; many will want to recompute their FY 2026-27 declaration
- Ensure landlord PAN is collected if annual rent exceeds Rs 1,00,000
Step 9: Communicate with Employees
The 50% rule typically reduces take-home pay in the short term while increasing retirement corpus and gratuity. Most employees see a lower in-hand salary and ask why.
Prepare a one-page communication that explains:
- Statutory requirement under the Code on Wages
- New CTC structure (component-wise breakdown, before and after)
- Effect on take-home, PF, gratuity, and leave
- Long-term benefit: higher retirement corpus, higher gratuity at separation
Step 10: Update Statutory Filings
| Filing | What Changes |
|---|---|
| Monthly EPF challan (ECR) | New Basic + DA used as PF base |
| Quarterly TDS Form 24Q | Reflect new salary structure |
| Form 16 / Form 130 (FY 2026-27 onwards) | Issued on new structure |
| Bonus payment to eligible employees | Computed on new wage base |
| Annual statutory returns | Updated wage figures |
Sample Restructuring Walk-Through
Before Restructuring (Common Legacy Pattern)
| Component | Monthly (Rs) | Annual (Rs) |
|---|---|---|
| Basic | 30,000 | 3,60,000 |
| HRA | 12,000 | 1,44,000 |
| Conveyance | 1,600 | 19,200 |
| Special Allowance | 50,400 | 6,04,800 |
| Gross Monthly | 94,000 | 11,28,000 |
| Employer PF | 1,800 | 21,600 |
| CTC | 95,800 | 11,49,600 |
Basic ratio = 30,000 / 94,000 = 31.9% → does not meet 50% rule
After Restructuring (50% Compliant)
| Component | Monthly (Rs) | Annual (Rs) |
|---|---|---|
| Basic | 47,000 | 5,64,000 |
| HRA | 12,000 | 1,44,000 |
| Conveyance | 1,600 | 19,200 |
| Special Allowance | 33,400 | 4,00,800 |
| Gross Monthly | 94,000 | 11,28,000 |
| Employer PF (on new Basic 47,000 capped at 15,000 base) | 1,800 | 21,600 |
| CTC | 95,800 | 11,49,600 |
Basic ratio = 47,000 / 94,000 = 50% → compliant
Gross monthly is unchanged; CTC is unchanged. Employee's take-home reduces by the higher employee PF deduction (12% × Rs 15,000 = Rs 1,800, same in this example because Basic was already above Rs 15,000). For lower-paid employees where Basic was below Rs 15,000, the take-home drops more.
Gratuity liability rises because the formula uses Basic + DA. For an employee with 10 years of service: gratuity changes from (15/26) × 30,000 × 10 = Rs 1.73 lakh to (15/26) × 47,000 × 10 = Rs 2.71 lakh. Provision the difference.
Compliance Checklist for FY 2026-27
- Map all employees' current CTC components
- Compute Basic + DA + Retaining Allowance as percentage of monthly recurring remuneration
- Identify employees below 50% threshold; prepare restructuring proposal
- Recompute PF contributions on the new Basic + DA base
- Run actuarial revaluation of accrued gratuity; provision the difference
- Update Bonus Act eligibility for employees up to Rs 21,000 wages
- Update leave encashment provisions
- Communicate restructuring to each affected employee individually
- Update payroll software with new component-wise structure
- Update HRA exemption logic for the four newly-metro cities (Hyderabad, Bengaluru, Pune, Ahmedabad)
- Plan Form 130 transition (replaces Form 16) from FY 2026-27 onwards
- Update offer letters and appointment letters issued from April 2026 onwards
- Brief HR and finance teams on the new wage definition
- Maintain documentation for any future labour inspection
Risks of Not Implementing
If your organisation continues with a sub-50% Basic structure into FY 2026-27 and a labour inspector audits:
- Statutory shortfall recovery: PF, gratuity, and bonus underpayment will be recovered with interest and damages
- Damages: up to 25% of the delayed contribution under EPFO rules
- Legal exposure: under Section 56 of the Code on Wages, contraventions attract penalty up to Rs 50,000 (first offence) and up to Rs 1 lakh + imprisonment for repeat offences
- Reputational risk: especially for companies fundraising or undergoing M&A due diligence; structural non-compliance is a red flag
Industry-Specific Considerations
IT / Software Services
- Engineers and managers with high Special Allowance components are most affected. Restructure carefully to avoid take-home shocks.
- Stock-based compensation (ESOPs, RSUs) is outside the Code on Wages scope; no restructuring impact there.
Manufacturing
- Hourly and contract workers under Wage Code compliance need separate review.
- Many manufacturing firms already had Basic at 40-50% of CTC; less restructuring required.
Startups and Early-Stage Companies
- Lean teams with allowance-heavy CTC structures will see the largest impact. Restructure before the next appraisal cycle to align with the new normal.
- Founder-employees on equity-heavy compensation: review the cash component separately.
Services Firms (Consulting, Marketing)
- Variable pay components (incentives, retention bonus) are outside the basic wage definition but still subject to the 50% allowance cap on the recurring portion.
