Eastern India's Lowest — Counterintuitive Story
Despite being India's second-largest economy, West Bengal has the lowest statutory bonus in Eastern India.
| State | Unskilled MW (₹/mo) | 8.33% Bonus/Year (₹) | vs WB Zone A |
|---|---|---|---|
| Jharkhand | ₹13,046 | ₹13,046 | +26% |
| Odisha | ₹12,268 | ₹12,268 | +18% |
| Bihar | ₹11,332 | ₹11,332 | +9% |
| Assam | ₹10,340 | ₹10,340 | 0% (parity) |
| WB Zone A | ₹10,383 | ₹10,379 | Baseline |
| WB Zone B | ₹9,760 | ₹9,756 | -6.4% |
Why WB Lags Behind
West Bengal's semi-annual minimum wage revision (0.5–3.7% increments) has fallen far behind state neighbors like Jharkhand (+26% higher). While WB has India's second-largest economy and oldest industrial base, MW policy has not kept pace. This underpays workers relative to neighboring states — a "slow and steady" approach that has cost competitiveness.

Clockwork MW Revisions — Semi-Annual Bonus Base Change
West Bengal revises minimum wages every January and July. This creates two different bonus calculation bases per financial year.
| Period (FY 2025-26) | MW Applicable | Bonus Base | Months |
|---|---|---|---|
| Jan 1 – Jun 30, 2026 | Jan 2026 MW | ₹10,383 (Zone A Unskilled) | 6 months |
| Jul 1 – Dec 31, 2025 | Jul 2025 MW | Previous Jul 2025 rate | 6 months |
| Bonus Payment (Nov 30, 2026) | Use weighted average | 6M×Jan MW + 6M×Jul MW ÷ 12 | Full year |
Correct Approach for FY 2025-26 Bonus
- Jan–Mar 2026: Use Jan 2026 MW (₹10,383 Zone A Unskilled)
- Apr–Jun 2026: Use Jan 2026 MW (same, no revision)
- Jul–Sep 2025 (in actual FY): Use Jul 2025 MW (TBD by July 2025)
- Oct–Dec 2025: Use Jul 2025 MW (same, no revision)
- Weighted Bonus Base: (Jan MW × 6 months + Jul MW × 6 months) ÷ 12

Step-by-Step WB Bonus Calculation — 6 Simple Steps
From "Am I covered?" to "File Form D" — straightforward for West Bengal's uniform sector system.
Step 1: Confirm Applicability (20+ Employees)
- Do you have 20+ employees in West Bengal? → Covered
- Fewer than 20 → Not covered
Step 2: Identify Eligible Workers
- Salary (Basic + DA) ≤ ₹21,000/month
- Worked 30+ days in FY 2025-26
- Not an apprentice
Step 3: Determine Zone & Skill Level
- Zone A: Kolkata, Howrah, Salt Lake, other municipal areas
- Zone B: Rest of West Bengal (smaller cities, rural)
- Skill: Unskilled, Semi-Skilled, Skilled, or HS (Higher Skilled) — use company classification
Step 4: Apply Correct MW Base
- Jan–Jun 2026: Use Jan 2026 MW (₹10,383 Zone A Unskilled)
- Jul–Dec 2025: Use Jul 2025 MW (TBD)
- Average for full-year bonus = (Jan MW × 6 + Jul MW × 6) ÷ 12
Step 5: Calculate Bonus Percentage
- Allocable surplus < 8.33% → Pay 8.33% minimum
- Allocable surplus 8.33%–20% → Pay actual surplus %
- Allocable surplus > 20% → Pay 20% maximum; set-on excess
Step 6: Pay & File by Deadline
- Pay: November 30, 2026 (FY 2025-26)
- File Form D: Within 30 days of payment
- Maintain: Forms A (surplus), B (set-on/set-off), C (employee-wise details)
