Section 54GB: meaning, how it works in India and examples

Section 54GB is a capital gains exemption. When a person sells a house or plot of land that they held for a long time, the profit is a long-term capital gain and is taxed. Section 54GB says that if the sale money is put into the shares of a qualifying startup, the gain can be exempt, fully or in proportion to the amount invested.

The idea is to steer money from property into new businesses. It is one of several sections, such as 54 and 54F, that exempt gains when money is reinvested. The Income-tax Act, 2025, which applies from 1 April 2026, carries similar provisions under new numbering, so the section number in use today should be checked.

Only an individual or an HUF, resident or non-resident, can claim. A company cannot. The asset sold must be a residential house or plot that qualifies as a long-term asset. The exemption is meant for the sale of a home, not of business assets.

Summaries note that the person claiming the exemption must be the one subscribing to the startup's shares, and must subscribe to new equity shares, not buy existing ones from another holder. The money goes into new shares, so the company receives it.

The company must be an eligible startup, a term the section borrows from the definition used for Section 80-IAC. In broad terms it is a private company incorporated in India that is recognised as a startup and was set up within the time allowed by the law. A practitioner guide also mentions a paid-up capital ceiling of ₹50 crore and a requirement of a minimum number of employees in some versions, but sources differ, so the statute is the place to confirm.

The tax law limits the benefit to a window of time. Summaries of the section show that the date by which the property must be transferred was extended a few times through Finance Acts. Whether a sale today still qualifies depends on the date in force in the current law, which this guide could not confirm from primary text, so it should be checked before planning around the section.

The seller first puts the net sale proceeds into the specified account scheme with a bank, if the money is not yet used before the due date for the tax return. Then the money is used to subscribe to shares. The company has to use that money to buy a specified asset, usually new plant, machinery or equipment, within one year, according to law-firm summaries. Money held as cash or placed in other shares does not count.

The exemption is proportionate. If only part of the net sale amount is put in, only the matching part of the gain is exempt. The stake rule also matters. Per one source reading the statute text, the investor must hold more than 25 per cent of the share capital or voting rights after subscribing, but sources vary, so the figure is one to verify.

• Sell a long-term residential property and make a long-term gain.
• Put the net proceeds in shares of an eligible startup, or in the deposit scheme before the return date.
• The startup buys the specified asset within a year.
• Hold the shares and the asset for five years.

The shares must be held for five years from the date of subscription. The startup must not sell or transfer the new asset in the same period either. If the lock-in is broken, the earlier exemption is reversed and the gain becomes taxable in the year of the breach. For this reason investors treat the exemption as a deferral that only holds when the startup survives and the investor stays put.

One summary notes that the period for some assets is shorter, at three years. Rules like this are exactly why professional advice matters here.

The exemption depends on several steps being completed in order and on time: the subscription, the deposit if the money is not yet used, the purchase of the asset by the startup and the five-year hold. If any of them fails, the exempt gain can become taxable in the year of the failure.

The startup's behaviour matters, not only the investor's. If the company does not buy the specified asset within the time allowed, or if it sells that asset within the lock-in, the investor loses the benefit through no act of their own. An investor should therefore read the startup's plans, ask for undertakings and keep records of each step.

The section does not judge the quality of the startup. It only gives a tax benefit. A young company can fail, and then the investor loses the capital, while the tax saved is smaller than the loss. Money from a house is often a family's main asset, so the risk is real. The tax saved should be weighed against the chance of losing the principal before choosing this route.

Many investors compare it with other options, such as using the gain to buy another house under Section 54 or investing in specified bonds under Section 54EC.

A person with a long-term gain from a home sale has other ways to save tax. Section 54 allows reinvestment in another residential house within the periods set, and Section 54EC allows investment in specified bonds up to a limit, with a lock-in. Each has its own conditions and ceilings, and each leaves the money in safer assets than a young startup.

The choice depends on how much risk the family can bear. A person who invests in a startup with money meant for a home or retirement risks both the tax saving and the principal. Some investors split the proceeds. Professional advice is especially useful here, because the right answer depends on the numbers.

Section 80-IAC helps the startup by removing tax on its profits. Section 54GB helps the investor by removing tax on a property gain. They are unrelated benefits, although both rely on the same startup definition. Angel investing in general is a separate subject and does not need a property sale. This guide is general information, not tax advice, so confirm the current law with a professional.
