Finance Act 2026/current-text control
Finance Act, 2026 substituted “three” for “one” in the eligible-start-up turnover condition, making the operative section 140 ceiling Rs 300 crore for the tax year of claim; other certification and formation conditions continue to apply.
Professional alert
Exception / professional alert Finance Act, 2026 raised the turnover wording to ₹300 crore in the operative text. Certification and non-reconstruction conditions remain central; Rule 66/Form 32 applies.

Worked application
A certified eligible start-up incorporated in 2022 chooses tax years 2026-27 to 2028-29 as its three consecutive claim years within the statutory ten-year window.
Evidence / compliance checklist
- Preserve incorporation records proving the eligible company/LLP was incorporated within the statutory window (section 140: Special provision in respect of specified business).
- Keep tax-year turnover evidence demonstrating the current Rs 300 crore ceiling and the certificate/recognition required by the section (section 140: Special provision in respect of specified business).
- Maintain records proving the business was not formed by prohibited splitting, reconstruction or transfer of previously used plant and machinery (section 140: Special provision in respect of specified business).
- Where Rule 66 applies, obtain Form 32 and reconcile the accountant-certified three-out-of-ten-year profit claim to the return before the due date (section 140: Special provision in respect of specified business).
Common mistake
Assuming start-up recognition by itself establishes the deduction, or continuing to use the old Rs 100 crore turnover ceiling. Section 140 separately requires the current incorporation window, Rs 300 crore turnover ceiling, qualifying business/formation conditions, audit evidence and a valid three-out-of-ten-year claim.
Recommended approach
For section 140, fix the governing tax year, identify the operative sub-section for “Special provision in respect of specified business”, trace every amount to evidence, apply only verified Rule/Form links, and retain a computation that another reviewer can reproduce from the primary source.

Current statutory text
140. (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.
