BOCW cess: what the 1% is, who pays it, and what you get for it
5 min read · Last reviewed 7 August 2026
One percent sounds small until you price a job without it. On a ₹2 crore contract the BOCW cess is ₹2 lakh, deducted from your bill, and unlike TDS it never comes back.
It is the deduction contractors most often leave out of a quote, which makes it the deduction most often paid out of profit.
What it is
The Building and Other Construction Workers Welfare Cess Act 1996 levies a cess on construction work to fund a welfare board for construction labour — accident compensation, pensions, education and medical assistance for registered workers.
It is not a tax on your profit. It is a levy on the cost of construction, and the client deducts it at source in the same way as TDS.
The rate and the base
- The rate is 1% of the cost of construction.
- It applies where the cost of construction exceeds ₹10 lakh.
- It is charged on the construction value — not on the GST, and not on the cost of land.
- The client deducts it from your running bills and remits it to the welfare board.
Why it is different from every other deduction
That last row is the whole point. Every other deduction on your bill is your money held temporarily. The cess is spent, and the only thing that comes back is a welfare fund your workers can draw on.
| Deduction | Typical rate | Recoverable? |
|---|---|---|
| Income-tax TDS (194C) | 1% or 2% | Yes — credited in Form 26AS |
| GST TDS (s.51) | 2% | Yes — credited to your GST cash ledger |
| Security deposit / retention | 5% to 10% | Yes — released on completion |
| BOCW cess | 1% | No — it is a cost |
What you should be doing about it
- Price it into every quote. On a job with a 5% margin, forgetting a 1% cess removes a fifth of your profit.
- Register your establishment under the BOCW Act if you employ ten or more construction workers — registration is a legal requirement, separate from the cess.
- Register your workers with the state welfare board. The cess is deducted whether or not they are registered; the benefits only reach them if they are.
- Check the deduction on each bill against the agreement clause. A cess charged on the gross when the contract says the work value is a real overcharge, and it recurs on every bill.
Common questions
- What is the BOCW cess rate?
- One percent of the cost of construction, levied under the Building and Other Construction Workers Welfare Cess Act 1996, where the cost of construction exceeds ₹10 lakh.
- Is BOCW cess charged on the amount including GST?
- It is levied on the cost of construction, which does not include GST. Departments differ in practice, though, and some deduct on the gross figure — on a ₹1 crore bill the difference is ₹18,000, so the agreement clause is worth reading before you quote.
- Can BOCW cess be claimed back or set off?
- No. Unlike income-tax TDS or GST TDS, which are credited back to you, and unlike security deposit, which is released on completion, the cess is a cost. It must be priced into the quote.
- Who deposits the BOCW cess?
- The client deducts it at source from your bills and remits it to the state construction workers welfare board. Where the client does not deduct it, the liability to pay still rests with the employer of the construction work.
