Section 54GB: Capital Gains Exemption for Investing in Eligible Startups

Finin2min Tax Desk·June 2026·7 min readCapital Gains

Most people know Section 54/54F lets you save capital gains tax by buying another house. Fewer know there's a section that lets you save the same tax by investing in a startup instead - aimed squarely at angel investors and family members backing early-stage companies.

What Is Section 54GB?

Section 54GB provides an exemption from long-term capital gains tax on the sale of a residential property (house or plot of land with a residential house), where the net consideration is invested in equity shares of an "eligible startup", subject to several conditions. This section was designed to channel capital from property sales into India's startup ecosystem while giving the seller a tax incentive.

Who Can Claim This Exemption?

The exemption is available to individuals and HUFs who:

What Is an "Eligible Startup"?

ConditionRequirement
IncorporationA company incorporated in India during the period specified under the relevant notification (extended periodically by the government)
RecognitionMust be recognized as an "eligible startup" by DPIIT (Department for Promotion of Industry and Internal Trade)
Shareholding conditionThe individual/HUF must hold more than 25% of the share capital or voting rights of the company after the subscription (or such other percentage as may be specified)
Turnover limitThe startup's turnover must not exceed the prescribed limit (as per the startup definition under the relevant notification) in any of the years since incorporation
The 50%+ shareholding requirement makes this primarily relevant for founders' family members, angel investors taking a significant stake, or co-founders - not for someone buying a small number of shares in a startup as a minority/passive investment. This is a key practical limitation that many taxpayers overlook.

Conditions on Use of Proceeds by the Startup

The startup company receiving the investment must utilize the amount for the purchase of new plant and machinery (or as otherwise specified for certain categories of startups, such as those in technology-driven sectors) within one year from the date of subscription of shares. If the amount is not utilized as required, the exemption may be withdrawn and the gain becomes taxable in the hands of the investor in the year the condition is violated.

Lock-in Period

The equity shares (or the assets purchased by the startup using the proceeds) are typically subject to a lock-in period of 5 years (this has been adjusted over various Finance Acts; always check the currently applicable period). If the shares are sold, or the company transfers the asset purchased, before this lock-in expires, the previously exempted capital gain becomes taxable as long-term capital gains in the year of such transfer.

Frequently Asked Questions

Can I claim Section 54GB by buying a small number of shares (say 5%) in a friend's startup?
Generally no. Section 54GB requires the investor to hold more than the prescribed minimum shareholding/voting rights percentage (historically over 25%, with specific conditions under the relevant notifications) in the eligible startup after the investment. A minor 5% stake would typically not satisfy this requirement, making the exemption unavailable for small passive investments.
What happens if the startup doesn't use the invested money for plant and machinery within the prescribed time?
If the eligible startup fails to utilize the invested amount as required (e.g., for purchase of new plant and machinery within one year, subject to specific category exceptions), the exemption claimed by the investor may be withdrawn, and the previously exempted capital gain becomes taxable as long-term capital gains in the year the violation occurs.
Is Section 54GB available for HUFs, or only individuals?
Both individuals and HUFs can claim the exemption under Section 54GB, subject to meeting all the prescribed conditions regarding the asset sold, the eligible startup, and the shareholding/lock-in requirements.
