Section 54GB: Capital Gains Exemption for Investment in Eligible Companies and Startups

Section 54GB of the Income-tax Act, 1961 provided conditional capital gains relief when an individual or Hindu undivided family sold qualifying long-term residential property and invested the net consideration in equity shares of an eligible Indian company, which in turn acquired qualifying new assets. Its time-bound eligibility rules are essential: this is not an unrestricted exemption for present-day property sales.

Important 2026 update: The Income-tax Act, 2025 applies from 1 April 2026, subject to its transitional and savings provisions. For a transfer occurring in an earlier year, determine the applicable version of section 54GB and its sunset date for that transfer year. The statutory extract below is an older version and does not incorporate every later amendment; do not use its 2017/2019 deadlines as a statement of the final amended law.

What is Section 54GB?

Section 54GB was introduced to encourage investment of gains from certain residential-property disposals into qualifying small or medium enterprises and, subject to later amendments, eligible startups. Unlike section 54F, which concerns investment in a residential house, section 54GB concerns investment in shares of an eligible company followed by that company's investment in prescribed business assets.

Principal eligibility requirements

  1. Eligible taxpayer: an individual or Hindu undivided family (HUF).
  2. Original asset: a long-term residential property, comprising a house or plot of land, within the version of the law applicable to the transfer.
  3. Equity subscription: the taxpayer uses the net consideration to subscribe to equity shares of an eligible company before the applicable section 139(1) return-filing due date.
  4. Company investment: the company uses the subscription proceeds to acquire qualifying new assets within one year from the date of share subscription, subject to the deposit mechanism.
  5. Eligible company: the company must satisfy the applicable incorporation, business, controlling shareholding/voting rights and MSME or eligible-startup requirements.
  6. Time-limited availability: the relevant property-transfer deadline and startup-specific amendments must be checked for the particular year. A qualifying business investment alone cannot revive a lapsed relief.

How the exemption is calculated

If the cost of the company's qualifying new assets is at least the net consideration, the entire eligible capital gain may be exempt. If that cost is less, the exemption is proportionate:

Exempt capital gain = Capital gain x (Qualifying new-asset cost / Net consideration)

Illustration: If a qualifying historical transfer produced a capital gain of Rs. 30 lakh, net consideration of Rs. 75 lakh and eligible new-asset expenditure of Rs. 60 lakh, the exemption would be Rs. 24 lakh (30 x 60 / 75), subject to all statutory conditions. The remaining Rs. 6 lakh would be taxable under the applicable rules.

Important statutory definitions

Eligible assessee

An individual or a Hindu undivided family.

Eligible company

An Indian-incorporated company meeting the statutory timing, eligible business, controlling shareholding or voting rights, and MSME or eligible-startup conditions. The detailed tests and the meaning of an eligible startup have changed through amendments; check the relevant year.

Net consideration

The full value of consideration for the property transfer less expenditure incurred wholly and exclusively in connection with that transfer, by reference to the definition in section 54F.

New asset

Generally qualifying new plant and machinery, subject to exclusions for previously used equipment, office or residential installations, office appliances, vehicles and assets whose whole cost is otherwise deductible. A specific statutory exception addressed computers and software for qualifying technology-driven startups.

Deposit of unspent company funds

Where the company had not used the full share-subscription amount by the taxpayer's applicable return-filing deadline, section 54GB required the unspent amount to be deposited in the prescribed account and used under the notified scheme. Amounts not used within the specified one-year period could lead to taxation of the previously exempt gain in the prescribed year. The company's right to withdraw unused deposits was governed by the scheme.

Five-year lock-in and withdrawal of relief

Under subsection (4), a sale or other transfer of the subscribed shares or qualifying new assets within five years of acquisition generally caused the earlier exempt gain to be brought to tax in the taxpayer's hands. Any separate gains on transfer of the shares or business assets could also be taxable. Verify the specific exceptions and amendments applicable to the relevant assessment year.

Historical sunset dates and later amendments

The original extract on this page states a general cut-off of 31 March 2017 and an eligible-startup extension to 31 March 2019. These reflect the historical text reproduced below, not a complete consolidation of subsequent Finance Act amendments. Later legislative changes extended the startup-related window. Before claiming any relief, verify the final applicable cutoff and all conditions against the official amended statute for the transfer date. The Income-tax Act, 2025 also requires attention for tax years beginning from 1 April 2026.

(4) If the equity shares of the company or the new asset acquired by the company are sold or otherwise transferred within a period of five years from the date of their acquisition, the amount of capital gain arising from the transfer of the residential property not charged under section 45 as provided in sub-section (1) shall be deemed to be the income of the assessee chargeable under the head "Capital gains" of the previous year in which such equity shares or such new asset are sold or otherwise transferred, in addition to taxability of gains, arising on account of transfer of shares or of the new asset, in the hands of the assessee or the company, as the case may be.
