[Analysis] BOCW Cess under Code on Social Security 2020 – Rate | Self-Assessment | Appeal

BOCW cess under the Code on Social Security 2020 is levied under Chapter VIII, sections 100 to 108. Sections 100 to 105 carry the scheme of the Building and Other Construction Workers' Welfare Cess Act, 1996; sections 106 and 107 come from the companion regulation Act of the same year, and section 108 has no predecessor. Section 100(1) fixes a band of not less than one and not more than two per cent of the cost of construction; the rate actually notified under it is one per cent, set by S.O. 2322(E) dated 8 May 2026 in supersession of S.O. 2899 dated 26 September 1996. The cost of construction excludes the cost of land. The employer pays in advance on a self-assessment certified by a chartered engineer, and files a final self-assessment within sixty days of completing each work.

Law stated as on 1 September 2026. The Code on Social Security, 2020 was brought into force in stages, the bulk of it with effect from 21 November 2025.

1. What Chapter VIII replaced

The Building and Other Construction Workers’ Welfare Cess Act, 1996 was one of the nine enactments repealed by section 164(1) of the Code on Social Security, 2020. Its provisions now sit in Chapter VIII, headed “Social Security and Cess in respect of Building and Other Construction Workers”, sections 100 to 108.

The chapter is wider than the Act it replaced, and this is the first thing to get right. Sections 100 to 105 carry the cess: levy and collection, interest, exemption, self-assessment, penalty and appeal. Sections 106 to 108 are not cess provisions at all. Section 106 provides for the registration of building workers as beneficiaries, section 107 for cessation as a beneficiary, and section 108 constitutes the Building and Other Construction Workers’ Welfare Fund into which the cess is credited.

Two of those three came from somewhere else. Sections 106 and 107 correspond to sections 12 and 14 of the Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act, 1996, which the Code did not repeal. Section 108 has no predecessor in either Act. So the tidy proposition that the Code took the cess and left the regulation is not quite right: it took the cess, and it took the beneficiary registration provisions with it. What remains of the 1996 regulation Act, including registration of establishments, welfare boards, hours and safety, sits outside the Code on Social Security. The Ministry of Labour and Employment’s Compliance Handbook for Employers under the Four Labour Codes sets out where the surviving obligations sit.

The Cess Act’s scheme did not survive in one place, and that is the second thing to get right. Six sections of Chapter VIII carry its core: section 100 corresponds to section 3, section 101 to section 8, section 102 to section 6, section 103 to sections 4 and 5, section 104 to section 9, and section 105 to section 11. The rest of the Cess Act went into the Code’s general chapters. Section 7 became section 122 on Inspector-cum-Facilitators, section 10 became section 129 on recovery of amount due, section 12 became section 133 on penalty for failure to pay contributions, section 13 became section 135 on offences by companies, section 14 became section 155 on the Central Government’s rule-making power, and section 15 became section 164 on repeal and savings. An employer who reads Chapter VIII on its own will not find the recovery machinery or the offence provisions, because they are no longer there. The wider mapping is set out in our note on the nine Acts subsumed in the Code.

2. The cess, and what the cost of construction leaves out

Section 100(1) levies a cess for the social security and welfare of building workers at a rate the Central Government notifies from time to time, not exceeding two per cent but not less than one per cent of the cost of construction incurred by an employer.

The rate now in force is one per cent. It was fixed by Notification No. S.O. 2322(E), dated 8 May 2026, issued under section 100(1), which specifies “a cess at the rate of one per cent of the cost of construction incurred by an employer on building or other construction work, with effect from the date of publication of this notification in the Official Gazette”. That notification supersedes S.O. 2899 dated 26 September 1996, the notification under the Cess Act that had carried the same one per cent since 1996. The rate did not change when the Code came in; the instrument fixing it did.

The band still matters, because the Code does not fix the rate, it fixes the room within which the rate may move. An employer pricing a multi-year project is exposed to a notification that doubles the levy without any amendment to the Code, and section 100(1) allows the Central Government to specify a rate “from time to time”.

The Explanation to section 100(1) removes two things from the cost of construction:

• the cost of land; and
• any compensation paid or payable to an employee or his kin under Chapter VII.

The first is the one that decides the number. On a project where land is a large share of total outlay, whether a cost sits on the land side or the construction side of that line is worth more than any argument about the rate. The second is narrower but principled: an employer does not pay cess on the compensation he has already paid for an employee’s injury or death.

3. Three ways the cess is collected

Section 100(2) does not prescribe a single mechanism. It requires collection from every employer undertaking building or other construction work, in the manner and at the time prescribed, and then names three routes:

Route	When it applies
Deduction at source	Building or other construction work of a Government or of a public sector undertaking
Advance collection through a local authority	Where approval of the work by a local authority, or by another authority notified by the State Government, is required
Direct payment by the employer	Everything else, in the prescribed manner and at the prescribed time

Where a local authority collects, section 100(3) requires it to deposit the proceeds with the Building Workers’ Welfare Board. Section 100(4) allows the cess, including advance payment of it, to be collected at a uniform rate on the basis of the quantum of work involved, subject to final assessment.

The practical reading of section 100(2) is that for a private project needing municipal approval, the cess is paid before the approval is granted. It is a precondition of getting started, not a liability that crystallises at the end.

4. Advance payment and the chartered engineer

Rule 41 of the Social Security (Central) Rules, 2026 supplies the machinery, and it is more demanding than section 100 suggests.

Information. Every employer must, within sixty days from the date of commencement of his work or of payment of cess, furnish information to the assessing officer in Form XV. Any change or modification must be communicated in Form XV immediately, and not later than thirty days from the date the change takes effect.

Advance payment on self-assessment. The cess is paid in advance, on the employer’s own self-assessment, duly certified by a chartered engineer, at the time of approval or before the work commences. That certification requirement is easy to miss and it is not optional.

How the cost is worked out. Rule 41(2)(b) does not leave the employer to his own figures. For self-assessment of the cost of construction he must calculate on the uniform rate or rates specified by the State Public Works Department or the Central Public Works Department, or any other schedule of rates applicable to that work, or the rates in the return or document submitted to the Real Estate Regulatory Authority where RERA applies, for the year in which the work commenced, in Form XVI.

That last limb is the one to note. For a RERA-registered project, the figure the employer has already given the regulator becomes a basis for the cess. Two documents that used to live in different files now have to agree.

Where approval by a local authority is required, Rule 41(2)(c) requires every application for that approval to be accompanied by proof of online payment made in favour of the State Building Workers’ Welfare Board, on a self-assessment certified by the chartered engineer. The proviso relieves long projects of finding the whole sum at the outset: if the duration of the project is likely to exceed one year, the payment may be limited to the cess on the cost of construction self-assessed to be incurred during one year from commencement, with further payments made as the work goes on.

Rule 41(2)(d) deals with Government and public sector work. The Government or the undertaking deducts the cess at the notified rates from the bills it pays for the work, and must deposit it with the State Building Workers’ Welfare Board within thirty days of the deduction, together with the details of the construction work.

Two further returns are easy to overlook. Under Rule 41(2)(e), any stoppage or reduction of the work must be reported to the assessing officer in Form XVII within sixty days. Under Rule 41(2)(f), a return in Form XVIII goes to the assessing officer within sixty days of each completed project. Rule 41(2)(g) then requires the advance cess to be adjusted in the final assessment order.

The scrutiny threshold. Rule 41(4)(a) is the provision most worth knowing, and it works in the employer’s favour. The assessing officer may scrutinise the Form XVIII return and make an order of assessment within a period not exceeding one hundred and eighty days from receiving it. But the first proviso confines scrutiny to cases where the amount of cess based on self-assessment exceeds rupees ten lakhs, and the second proviso provides that if the officer fails to make the order within those one hundred and eighty days, the self-assessment shall be deemed to be final. On the great majority of projects, the self-assessment is the assessment.

5. Final self-assessment under section 103

Section 103(1) closes the loop at the other end of the project. Within sixty days of the completion of each building and other construction work, or such period as the Central Government notifies, the employer must:

• pay the cess payable under Chapter VIII, adjusting the advance cess already paid under section 100;
• work the cess out on the basis of his own self-assessment of the cost of construction, on the documents and in the manner prescribed; and
• file a return under clause (d) of section 123.

Section 103(2) is the audit trigger. If the officer to whom the return is filed finds any discrepancy between the payment made under the self-assessment and the payment the return requires, he shall, after such inquiry as he thinks fit, make an appropriate assessment order. Section 103(3) requires that order to specify the date by which the cess is to be paid.

So there are two self-assessments on every project, one before it starts and one after it finishes, and the second is measured against the first. The discrepancy between them is what the assessing officer looks at.

6. Interest at one per cent a month

Section 101 makes an employer who fails to pay any amount of cess payable under section 100, within such time as the appropriate Government prescribes, liable to interest at such rate as the Central Government prescribes, for the period from the date payment falls due until the amount is actually paid.

Rule 42(2) fixes the rate at one per cent per month or part of a month from the due date until the date of actual payment. Rule 42(1) fixes the date of payment as the date the amount is deposited with the cess collector, or the date of deduction at source, or the date the amount is deposited with the local authority, depending on which route applied.

One per cent a month annualises to twelve per cent, which is also the rate notified for late payment under section 127 of the Code. The overlap is only apparent. Section 127 opens with the words “Except where expressly provided otherwise in this Code”, and section 101 is precisely such an express provision, so interest on cess runs under section 101 and Rule 42(2) and not under section 127. Section 127 carries no rate of its own either; twelve per cent per annum comes from Notification No. S.O. 2357(E), dated 8 May 2026, and again from S.O. 2698(E), dated 29 May 2026, which is deemed to have come into force on 21 November 2025.

The two rates look alike and do not behave alike. “Per month or part of a month” means that a delay of one day into a new month costs a full month’s interest, so the effective rate on a short delay is far above twelve per cent a year. The distinction is worth building into a payment calendar rather than discovering afterwards.

There is also a drafting point in Rule 42(2) worth noting. Section 101 runs interest from the expiry of the time prescribed for payment; Rule 42(2) runs it where the employer fails to pay within such time as may be specified in the assessment order. On the rule’s wording, interest on the advance cess is tied to the assessment order rather than to the date of the advance payment itself.

One comparison with the repealed Act runs the other way, and in the employer’s favour. Section 8 of the Cess Act, 1996 carried interest at two per cent for every month or part of a month. Rule 42(2) has halved it.

7. Penalty, and the way out of it

Section 104 applies where cess payable under section 103 is not paid by the date specified in the assessment order. The amount is then deemed to be in arrears, and the prescribed authority may, after such inquiry as it deems fit, impose a penalty not exceeding the amount of cess.

Two protections sit in the proviso, and the second is unusually generous:

• the employer must be given a reasonable opportunity of being heard before any penalty is imposed; and
• if, after that hearing, the authority is satisfied that the default was for any good and sufficient reason, no penalty shall be imposed.

Rule 43 supplies the machinery and names the officer. The prescribed authority for this purpose is the assessing officer, who must first issue a notice that the amount is deemed to be in arrears, and Rule 43(2) requires him to pass a speaking order whether he imposes the penalty or withdraws the notice, endorsed to the employer, the cess collector and the Secretary of the Building Workers’ Welfare Board. An employer who succeeds at the hearing is therefore entitled to a reasoned order recording why, and that order is worth having on file.

The wording is mandatory, not permissive. Where good and sufficient reason is established, the section does not allow a reduced penalty; it removes the penalty. That makes the hearing under section 104 the single most valuable step in the whole chapter, and it is one an employer can lose by treating a penalty notice as a payment demand rather than as an invitation to explain.

8. Appeal, and why the order is final

Section 105(1) gives an employer aggrieved by an assessment order under section 103, or by a penalty order under section 104, a right of appeal to the prescribed appellate authority, within the prescribed time and in the prescribed form.

Rule 44 supplies the detail. The appeal is filed in Form XIX, within ninety days of receipt of the order, to the appellate authority notified by the State Government. Rule 44(2) lists what must go with it: the order appealed against; a certificate from the cess collector that the cess or penalty, or both, has been deposited; a non-refundable fee of one-half per cent of the amount in dispute or penalty, capped at rupees twenty-five thousand; a statement of the points in dispute; and the documentary evidence relied upon.

The deposit can be waived. The proviso to Rule 44(2)(b) is the most useful line in the rule and it is almost never quoted: the appellate authority may, for reasons to be recorded in writing, waive or reduce the amount to be deposited under rule 43 on application by the appellant. Two things follow from the drafting. The waiver has to be applied for; it does not come with the appeal. And it is expressed to reach the amount deposited under rule 43, which is the penalty, rather than the cess assessed under rule 41(4). An appellant seeking relief from the whole deposit should say so expressly and should not assume the point is covered.

Section 105(3) requires the appellate authority to give the appellant an opportunity of being heard and then dispose of the appeal as expeditiously as possible. The section fixes no outer limit. The rule does. Rule 44(4) requires the appeal to be disposed of “as expeditiously as possible but not exceeding sixty days from the date of receipt of such appeal”, which is a good deal tighter than the six months the proviso to section 126 allows for an ESI appeal. Rule 44(8) requires a speaking order, copied to the appellant, the assessing officer and the Secretary of the Building Workers’ Welfare Board within five days of the date on which it is made.

Rule 44(5) sets the limits of what the appellate authority may do with the assessment. It may confirm it; if the assessment was wrong or on the higher side it may modify it; but if the assessment was on the lower side, or the basis of assessment was wrong, it must remand the order to the assessing officer with its observations rather than deciding the point itself. A remand is to be disposed of within thirty days under Rule 44(6), and the proviso to that sub-rule requires a hearing before any enhancement. Rule 44(11) closes the door on a second appeal.

Section 105(4) is the provision to read before deciding how hard to fight the assessment: every order passed in appeal shall be final and shall not be called in question in any court of law. A finality clause of that kind does not oust the writ jurisdiction of the High Court under Article 226, but it does mean the appeal is the last merits hearing an employer will get. Whatever is going to be argued about the cost of construction should be argued there.

9. Frequently asked questions

What is the rate of BOCW cess under the Code on Social Security?

The notified rate is one per cent of the cost of construction. It was fixed by Notification No. S.O. 2322(E), dated 8 May 2026, under section 100(1), in supersession of S.O. 2899 dated 26 September 1996. Section 100(1) itself sets a band rather than a figure: the cess is levied at such rate as the Central Government may, by notification, from time to time specify, not exceeding two per cent but not less than one per cent of the cost of construction incurred by an employer. The rate can therefore be moved by notification without any amendment to the Code.

Is the cost of land included in the cost of construction?

No. The Explanation to section 100(1) excludes the cost of land from the cost of construction, and also excludes any compensation paid or payable to an employee or his kin under Chapter VII of the Code.

When must BOCW cess be paid?

In advance, on a self-assessment certified by a chartered engineer, at the time of approval or before the work commences, under Rule 41(2)(a). A final self-assessment follows within sixty days of the completion of each work under section 103(1), adjusting the advance already paid, with a return filed under section 123(d).

What is the interest on late payment of BOCW cess?

Rule 42(2) of the Social Security (Central) Rules, 2026 fixes interest at one per cent per month or part of a month, running from the due date until the date of actual payment. Because part of a month counts as a whole month, a short delay carries a disproportionately high effective rate.

Can a penalty for late payment of cess be avoided?

Yes. Under the proviso to section 104, the employer must be given a reasonable opportunity of being heard, and if the authority is then satisfied that the default was for any good and sufficient reason, no penalty shall be imposed. The provision is mandatory in terms, so establishing good and sufficient reason removes the penalty rather than reducing it.

How long does a cess appeal take, and can the deposit be waived?

The appeal is filed in Form XIX within ninety days of receipt of the order under Rule 44(1) of the Social Security (Central) Rules, 2026. Section 105(3) requires the appellate authority to give the appellant an opportunity of being heard, and Rule 44(4) requires the appeal to be disposed of as expeditiously as possible but not exceeding sixty days from the date of receipt of the appeal. The proviso to Rule 44(2)(b) allows the appellate authority, for reasons to be recorded in writing, to waive or reduce the amount to be deposited under rule 43 on an application by the appellant.

Does Chapter VIII deal with anything besides the cess?

Yes. Chapter VIII runs from section 100 to section 108. Sections 100 to 105 carry the cess. Section 106 provides for the registration of building workers as beneficiaries, section 107 for cessation as a beneficiary, and section 108 constitutes the Building and Other Construction Workers’ Welfare Fund into which the cess is credited. Sections 106 and 107 correspond to sections 12 and 14 of the Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act, 1996, which the Code did not repeal.

10. Conclusion

Chapter VIII runs to nine sections, and almost all of the risk in it sits in two numbers and one date. The numbers are the cost of construction, where the exclusion of land decides the base, and the notified rate, currently one per cent under S.O. 2322(E) dated 8 May 2026, which can move anywhere within the one-to-two per cent band without any amendment to the Code. The date is the sixtieth day after completion of each work, when the final self-assessment falls due and the advance already paid is measured against it.

Everything after that is consequence. Interest runs at one per cent for every month or part of a month. Penalty can equal the whole cess but disappears entirely on good and sufficient reason shown at a hearing. The appeal must be filed within ninety days and decided within sixty, and the appellate order is final.
