Statutory text
Bare law
(1) Where the gross total income of an assessee, being an eligible start-up, includes any profits and gains derived from eligible business, there shall, as per and subject to the provisions of this section, be allowed, in computing the total income of the assessee, a deduction of an amount equal to 100% of the profits and gains derived from such business for three consecutive tax years.
(2) The deduction specified in sub-section (1) may, at the option of the assessee, be claimed by him for any three consecutive tax years out of ten years beginning from the year in which the eligible start-up is incorporated.
(3) This section applies to a start-up which fulfils the following conditions:— (a) it is not formed by splitting up, or the reconstruction, of a business already in existence; (b) it is not formed by the transfer to a new business of machinery or plant previously used for any purpose.
(4) Where the business of any undertaking carried on in India is discontinued in any tax year by reason of extensive damage to, or destruction of, any building, machinery, plant or furniture owned by the assessee and used for the purposes of such business as a direct result of— (a) flood, typhoon, hurricane, cyclone, earthquake or other convulsion of nature; or (b) riot or civil disturbance; or (c) accidental fire or explosion; or (d) action by an enemy or action taken in combating an enemy (whether with or without a declaration of war), and thereafter, at any time before the expiry of three years from the end of such tax year, the business of such undertaking is re-established, reconstructed or revived by the assessee, the condition referred to in sub-section (3)(a) shall not apply to such undertaking which is so re-established, reconstructed or revived.
(5) For the purposes of sub-section (3)(b), any machinery or plant which was used outside India by any person other than the assessee shall not be regarded as machinery or plant previously used for any purpose, if all the following conditions are fulfilled:— (a) such machinery or plant was not, at any time previous to the date of the installation by the assessee, used in India; (b) such machinery or plant is imported into India; and (c) no deduction on account of depreciation in respect of such machinery or plant has been allowed or is allowable under the provisions of this Act in computing the total income of any person for any period prior to the date of the installation of the machinery or plant by the assessee.
(6) Where in the case of a start-up, any machinery or plant or any part thereof previously used for any purpose is transferred to a new business and the total value of the machinery or plant or part so transferred does not exceed 20% of the total value of the machinery or plant used in the business, then, for the purposes of sub-section (3)(b), the condition specified therein shall be deemed to have been complied with.
(7) Irrespective of anything contained in any other provision of this Act, the profits and gains of an eligible business to which the provisions of sub-section (1) apply shall, for the purposes of determining the quantum of deduction under that sub-section for the tax year immediately succeeding the initial tax year or any subsequent tax year, be computed as if such eligible business was the only source of income of the assessee during the initial tax year and to every subsequent tax year up to and including the tax year for which the determination is to be made.
(8) The deduction under sub-section (1) from profits and gains derived from an eligible business shall not be admissible unless the accounts of the eligible business for the tax year for which the deduction is claimed have been audited by an accountant, before the specified date referred to in section 63 and the assessee furnishes by that date the report of such audit in the prescribed form duly signed and verified by such accountant.
(9) In a case where, any goods or services held— (i) for the purposes of the eligible business are transferred to any other business carried on by the assessee; or (ii) for the purposes of any other business carried on by the assessee are transferred to the eligible business, and, in either case, the consideration, if any, for such transfer as recorded in the accounts of the eligible business does not correspond to the market value of such goods or services as on the date of the transfer, then, for the purposes of the deduction under this section, the profits and gains of such eligible business shall be computed as if the transfer, in either case, had been made at the market value of such goods or services as on that date.
(10) For the purposes of sub-section (9), where, in the opinion of the Assessing Officer, the computation of the profits and gains of the eligible business in the manner hereinbefore specified presents exceptional difficulties, the Assessing Officer may compute such profits and gains on such reasonable basis as he may deem fit.
(11) For the purposes of sub-section (9), “market value”, in relation to any goods or services, means— (i) the price that such goods or services would ordinarily fetch in the open market; or (ii) the arm’s length price as defined in section 173(a), where the transfer of such goods or services is a specified domestic transaction referred to in section 164.
(12) Where any amount of profits and gains of an undertaking or of an enterprise in the case of an assessee is claimed and allowed under this section for any tax year, deduction to the extent of such profits and gains shall not be allowed under any other provisions of Part C of this Chapter and shall in no case exceed the profits and gains of such eligible business of undertaking or enterprise, as the case may be.
(13) Where it appears to the Assessing Officer that owing to the close connection between the assessee carrying on the eligible business to which this section applies and any other person, or for any other reason, the course of business between them is so arranged that the business transacted between them produces to the assessee more than the ordinary profits which might be expected to arise in such eligible business, the Assessing Officer shall, in computing the profits and gains of such eligible business for the purposes of the deduction under this section, take the amount of profits as may be reasonably deemed to have been derived therefrom.
(14) Where the arrangement as mentioned in sub-section (13) involves a specified domestic transaction referred to in section 164, the amount of profits from such transaction shall be determined having regard to arm’s length price as defined in section 173(a).
(15) The Central Government may, after making such inquiry as it may think fit, direct, by notification, that the exemption conferred by this section shall not apply to any class of industrial undertaking or enterprise with effect from such date as it may specify in the notification.
(16) For the purposes of this section,— (a) “eligible business” means a business carried out by an eligible start-up engaged in innovation, development or improvement of products or processes or services or a scalable business model with a high potential of employment generation or wealth creation; (b) “eligible start-up” means a company or a limited liability partnership engaged in eligible business which fulfils the following conditions:— (i) it is incorporated on or after the 1st April, 2016 but before the 1st April, 2030; (ii) the total turnover of its business does not exceed three hundred crore rupees in the tax year relevant to the tax year for which deduction under sub-section (1) is claimed; and (iii) it holds a certificate of eligible business from the Inter-Ministerial Board of Certification as may be notified by the Central Government; (c) “limited liability partnership” means a partnership referred to in section 2(1)(n) of the Limited Liability Partnership Act, 2008 (6 of 2009).
Introduction
An eligible start-up may deduct 100% of profit from an eligible business for three consecutive tax years, chosen within the statutory window. Incorporation timing, turnover, certification and how the business was formed require a separate eligibility review.
Key takeaways
Eligible start-up profits
An eligible start-up can deduct 100% of qualifying business profits for any three consecutive tax years it chooses within ten years from incorporation.
Certification and audit
Eligibility requires the statutory incorporation, turnover and certification conditions, plus the specified accounts audit and timely report.
What the deduction gives you
Where an eligible start-up's gross total income includes profits and gains from its eligible business, 100% of those profits and gains can be deducted for three consecutive tax years.
The three years don't have to be the startup's first three years - they can be any three consecutive years chosen out of the ten years beginning from the year the startup was incorporated, at the startup's own option.
Conditions to qualify
Subsection (3) imposes two formation conditions, subject to the exceptions below. They are part of the eligibility test and do not replace the definition and other requirements in the section.
- It was not formed by splitting up or reconstructing a business that already existed.
- It was not formed by transferring machinery or plant previously used for another purpose into the new business.
An exception worth knowing about
If a business is discontinued because of extensive damage or destruction (flood, earthquake, riot, fire, enemy action, and similar events), and the business is re-established, reconstructed or revived within three years of the end of that tax year, the "not formed by reconstruction" condition above does not disqualify it.
Eligible business, incorporation, turnover and certificate
The eligible start-up must be a company or LLP incorporated on or after 1 April 2016 and before 1 April 2030. Its turnover must not exceed ₹300 crore in the tax year relevant to the claim. It must hold a certificate of eligible business from the Inter-Ministerial Board of Certification notified by the Central Government.
Eligible business includes innovation, development or improvement of products, processes or services, or a scalable business model with high potential for employment generation or wealth creation. Check the actual statutory certificate and business criteria rather than treating a registration label as sufficient.
Previously used machinery exceptions
Machinery previously used outside India by a person other than the assessee is not regarded as previously used for this condition if it was never previously used in India, is imported into India, and no Act depreciation was allowed or allowable to any person for a period before the assessee installed it.
The formation condition is deemed satisfied where previously used machinery or plant transferred to the new business does not exceed 20% of the total machinery or plant value used in the business. Other eligibility requirements continue to apply.
Audit, profit computation and connected transactions
Accounts of the eligible business must be audited before the section 63 specified date, and the signed and verified audit report furnished by that date. For deduction quantum, the eligible business is treated as the only source from the initial tax year through the relevant claim year.
Transfers between the eligible and other businesses are tested at market value. Specified domestic transactions use the statutory arm’s-length price rules; exceptional computation difficulty permits a reasonable basis. Arrangements producing more than ordinary profits may be adjusted, and the same eligible profits cannot receive another Part C deduction beyond the permitted amount.
Step-by-step flow for applying Section 140
- 1
Is the assessee an eligible start-up?
Section 140(16)(b): a company or LLP engaged in eligible business, incorporated on or after 1 April 2016 but before 1 April 2030, with turnover not exceeding ₹300 crore for the relevant tax year, and holding a certificate of eligible business from the notified Inter-Ministerial Board of Certification.
- No: No deduction under Section 140.
- Yes: Go to the next step.
- 2
Does it meet the formation conditions in Section 140(3)?
It must not be formed by splitting up or reconstruction of an existing business (subject to the Section 140(4) revival exception), or by transfer of previously used machinery or plant. Section 140(5) treats certain imported machinery as not previously used, and Section 140(6) deems the condition met if transferred used machinery is not more than 20% of total machinery or plant value.
- Not met: No deduction under Section 140.
- Met: Go to the next step.
- 3
Is this tax year one of the three consecutive years chosen within the ten-year window?
Section 140(2): any three consecutive tax years out of ten years beginning with the year of incorporation, at the assessee's option.
- No: No deduction for this tax year.
- Yes: Go to the next step.
- 4
Are the accounts audited and the report furnished by the Section 63 specified date?
Section 140(8) makes the audit and the prescribed report a condition of the deduction.
- No: Deduction not admissible.
- Yes: Go to the next step.
- 5
Compute eligible profits and deduct 100%
Compute profits as if the eligible business were the only source (Section 140(7)), at market value for inter-business transfers (Section 140(9) to (11)), subject to Assessing Officer adjustment for more than ordinary profits (Section 140(13), (14)). No other Part C deduction on the same profits (Section 140(12)).
Practical checklist
Do
- Verify the start-up's incorporation date, qualifying business, certification and applicable turnover condition.
- Choose and document three consecutive claim years within the permitted overall period, with separate eligible-business accounts.
Avoid
- Do not assume any newly incorporated company automatically qualifies.
- Do not treat the three-year deduction as renewable or select nonconsecutive years.
Illustrative example
Worked example: choosing the claim years and the 20% machinery test
Hypothetical facts (illustration only, not a real taxpayer): A private company incorporated in 2021 develops a new process-automation product and holds the Inter-Ministerial Board certificate of eligible business. Year 1 is the tax year of incorporation. When it set up, it took over used machinery worth ₹15 lakh from a promoter's other business; total machinery and plant used in the business was ₹1 crore. It expects losses in Years 1 to 3 and profits from Year 4. In Year 4 its turnover is ₹40 crore and profit from the eligible business is ₹2 crore (assumed).
Incorporation and turnover
Incorporated after 1 April 2016 and before 1 April 2030; Year 4 turnover of ₹40 crore does not exceed ₹300 crore.
Used machinery test
₹15 lakh is 15% of ₹1 crore, which does not exceed 20%, so Section 140(6) deems the Section 140(3)(b) condition complied with.
Choice of years
The company opts for Years 4, 5 and 6, which are three consecutive tax years within the ten years beginning with Year 1 (Years 1 to 10).
Deduction for Year 4
100% of ₹2 crore = ₹2 crore, provided the accounts are audited and the report furnished by the Section 63 specified date.
Outcome
- The Year 4 deduction is ₹2 crore; Years 5 and 6 are computed the same way on those years' eligible profits, provided turnover and other conditions are met in each year.
- No deduction is available for Years 7 to 10 once the three chosen years are used, and the company cannot pick non-consecutive years.
Glossary
- Eligible start-up
- A start-up meeting the definition and conditions in Section 140.
- Eligible business
- The qualifying innovation, development or improvement activity described by the section.
Frequently asked questions
Is this the deduction people call "80-IAC"?
Yes - the profile is the same (100% profit deduction for 3 consecutive years out of the first 10 for an eligible startup), now under Section 140 of the Income-tax Act, 2025.
Do I have to claim the deduction starting from year one?
No - you can choose any three consecutive years out of your startup's first ten years to claim the 100% deduction, whichever three years make the most sense for your business.
Does DPIIT recognition automatically give me this deduction?
Recognition alone does not establish every requirement of section 140. Subsection (16)(b) specifically requires the eligible-business certificate from the notified Inter-Ministerial Board of Certification, as well as the incorporation and turnover conditions. Formation, audit and other conditions must also be satisfied.
