Section 80-IA is one of the most litigated deductions in Indian tax, and the arguments almost never start with the audit report. They start with a single question: were you developing the infrastructure, or were you just building it for someone who was?
Sub-section (7) is the part that ties the deduction to a Chartered Accountant’s report in Form 10CCB. It is the easy condition to satisfy and the expensive one to forget.

What sub-section (7) requires
Section 80-IA gives a profit-linked deduction to enterprises engaged in developing infrastructure facilities, generating or distributing power, running industrial parks or SEZs, and providing telecommunication services. Sub-section (7) attaches the condition: the accounts of the undertaking must be audited by an accountant, and the report furnished in the prescribed form.
That form is Form 10CCB, whose official heading under Rule 18BBB reads “Audit report under section 80-I(7)/80-IA(7)/80-IB/80-IC”. One form, several deductions.
The undertaking is the unit of account, not the company. Profits of the eligible undertaking are computed as though it were the only business the assessee carried on. Each undertaking needs its own report, its own profit and loss account and its own balance sheet.
The distinction that decides most cases
The deduction goes to the developer of an infrastructure facility, not to a contractor executing work for a developer. A company that builds a road under a works contract, carries no project risk, and is paid on running bills is generally a contractor. A company that invests, bears risk and operates the facility is generally a developer.
This is where the money is won or lost. Form 10CCB records the facts — the nature of the agreement, the dates, the authority involved — that support the characterisation. A report completed carelessly on those points weakens the position badly if the claim is questioned later.
Most limbs of 80-IA have sunset. The dates by which the undertaking had to begin operating have passed for infrastructure, power and telecom. In practice 80-IA now arises for undertakings already inside their ten-year deduction window, not for new claims. Confirm the commencement date before assuming a claim is available at all.
Core conditions
| Condition | Substance |
|---|---|
| Ownership | The enterprise must be an Indian company or a statutory authority, for infrastructure facilities |
| Agreement | An agreement with the Central Government, a State Government, a local authority or a statutory body |
| Commencement | Operation must have begun within the period specified for that activity |
| Deduction period | 100% of profits for 10 consecutive years, chosen from the first 15 (20 for some facilities) |
| Audit | Form 10CCB, one report per undertaking |
| Market-price rule | Inter-unit transfers must be recorded at market value, or the Assessing Officer may recompute |
Timing
The report must be furnished electronically one month before the due date for the return. Where the return is due 31 October, Form 10CCB is due 30 September. It is not part of the return package, and teams that assume otherwise find out a month late.
UDIN on Form 10CCB
Form 10CCB is signed by a practising Chartered Accountant and falls in the Certificates category, where UDIN has been mandatory since 1 February 2019.
An unupdated UDIN can invalidate the report. The form may be uploaded without a UDIN, but the number must be updated within 60 calendar days of upload. If it isn’t, the CBDT treats the uploaded form as invalid with all due consequences of law — even after the assessee has accepted it. For a deduction spanning ten years, that is a large consequence from a small omission.
Revocation is possible only within 48 hours of generation, and an error found after acceptance requires a revised form with a fresh UDIN rather than an edit. See our guide to UDIN generation.

Frequently asked questions
What does section 80-IA(7) actually require?
That the accounts of the eligible undertaking are audited by an accountant and the report furnished in Form 10CCB.
When is Form 10CCB due?
One month before the due date for furnishing the return — 30 September where the return is due 31 October.
Can a contractor claim 80-IA?
Generally no. The deduction is for the developer of an infrastructure facility. A contractor executing work for a developer, without project risk, is usually outside it.
Do we need a separate Form 10CCB for each project?
Yes. One report per eligible undertaking, with accounts drawn up as if it were a separate business.
Is 80-IA still available for new projects?
Largely not. The commencement deadlines for most limbs have passed. It now mainly affects undertakings already within their deduction window.
How long does the deduction run?
100% of profits for ten consecutive years, chosen out of the first fifteen — twenty for certain facilities.
Is UDIN required?
Yes, in the Certificates category. It must be updated within 60 calendar days if the form is uploaded without one.
What if profits are shifted between units?
Transactions between the eligible undertaking and other businesses must be recorded at market value. Otherwise the Assessing Officer may recompute the deduction.
Which section replaces 80-IA under the new Act?
Section 138 of the Income-tax Act, 2025.
Can a Cost Accountant sign Form 10CCB?
No. It must be signed by a Chartered Accountant in practice.
In short
Section 80-IA(7) is a procedural condition guarding a substantive benefit. The substantive fight is almost always about whether you developed the facility or merely built it — and Form 10CCB is where the facts supporting that answer are first recorded. Fill it as though it will be read by an Assessing Officer years later, because it may well be.
