What is BOCW cess?
BOCW cess is a welfare levy on the cost of building and other construction work, used for construction workers' welfare boards. Under the Code on Social Security, 2020, the rate can be 1–2% of construction cost, and a notification dated 8 May 2026 fixed it at 1%. Land cost is excluded, and the employer pays it in advance on a self-assessment.
What changed in 2026
- New home in the law. The Building and Other Construction Workers' Welfare Cess Act, 1996 gave way to Chapter VIII of the Code on Social Security, 2020 (Taxmann analysis).
- Rate fixed at 1%. Section 100(1) allows 1–2% of construction cost. The Labour Ministry notification S.O. 2322(E) dated 8 May 2026 set it at 1% (notification text).
- Self-assessment. Cess is paid in advance on a self-assessment, with a final assessment within 60 days of completing the work, as reported by Taxmann. The detailed procedure is in the rules, so confirm it with your consultant.
Worked example
| Line | Working | Amount |
|---|---|---|
| Construction cost, excluding land | ₹4,00,00,000 | |
| Cess @ 1% | ₹4,00,00,000 × 1% | ₹4,00,000 |
| Deduction on an RA bill of ₹50,00,000 | ₹50,00,000 × 1% | ₹50,000 |
| Over 8 equal RA bills | 8 × ₹50,000 | ₹4,00,000 |
On government work, the cess is commonly deducted at source from each RA bill. Over the job, the deductions should add up to the self-assessed total, with any difference trued up at final assessment.
Who pays BOCW cess: owner or contractor?
The law puts the duty on the "employer" of the construction work, which can mean the owner, the contractor, or both, depending on the arrangement. In practice, your tender decides who bears it. For example, a BHEL tender corrigendum of January 2026 makes civil contractors bear the cess within their quoted price (BHEL corrigendum). Price your bid accordingly, and make sure the cess isn't deducted twice, once by the owner and again on your own subcontractors for the same work.
