Capital Gains Exemptions 2026: Property Sale, House Reinvestment, 54F & Mutual Funds

Capital-gains exemption depends on what you sold, when you sold it and where you reinvest. Selling a residential house, selling another long-term asset such as shares or mutual-fund units, and investing sale proceeds back into mutual funds are not treated the same way. A common mistake is assuming that reinvesting sale proceeds anywhere automatically saves capital-gains tax.

First identify the asset and the date of transfer

The first step is not to choose an exemption section. It is to identify the asset sold, determine whether the gain is short-term or long-term under the rules applicable to that transfer date, compute the gain correctly and then test whether a specific rollover exemption is available.

Important change: do not use old capital-gains rates blindly

Older articles often state that long-term property gains are always taxed at 20% with indexation and that equity long-term gains are taxed at 10% above a ₹1 lakh threshold. Those statements are not safe as a general 2026 rule. The Finance (No. 2) Act, 2024 materially changed capital-gains rates and holding-period rules for transfers on or after 23 July 2024. Current Income Tax Department return validations also distinguish transfers before and on/after 23 July 2024.

For example, the department's current guidance reflects 20% short-term capital-gains tax for qualifying STT-paid equity transactions and 12.5% long-term capital-gains rates in specified cases after the 23 July 2024 changes. Property and other assets also require transfer-date-specific analysis, including the special grandfathered comparison available in certain resident-individual/HUF land or building cases acquired before 23 July 2024. Therefore, compute the tax first under the law applicable to the transfer date and only then apply any exemption.

Residential house sold: legacy Section 54 framework

For a transaction governed by the old Income-tax Act, 1961, the familiar Section 54 framework generally allowed an individual or HUF to claim exemption when long-term capital gain arose from transfer of a qualifying residential house and the taxpayer purchased or constructed another residential house in India within the prescribed period.

The commonly used time windows were purchase within one year before or two years after transfer, or construction within three years after transfer. The exemption was generally restricted by the amount of qualifying capital gain and the eligible investment. The official Income Tax Department tutorial, as amended by Finance Act 2025, also notes a maximum ₹10 crore amount for the exemption computation.

The old provision additionally contained a one-time option involving investment in two residential houses in India where the long-term capital gain did not exceed ₹2 crore, subject to the statutory conditions.

If the asset sold was not a residential house: legacy Section 54F concept

Under the old Act, Section 54F applied to an individual or HUF where long-term capital gain arose from transfer of a long-term capital asset other than a residential house and the taxpayer invested in a residential house in India, subject to ownership and investment conditions. This relief was different from Section 54 because the proportion of net consideration invested could affect the amount of exemption.

Accordingly, a taxpayer who sold mutual-fund units, shares, land or another qualifying long-term asset could not simply assume that the entire gain was exempt because a house was purchased. The statutory formula, ownership restrictions and timing conditions all had to be checked.

What changed from 1 April 2026?

The Income-tax Act, 1961 stands repealed from 1 April 2026 and the Income-tax Act, 2025 applies for current tax years, subject to its transition and savings provisions. This means articles that refer only to “Section 54” or “Section 54F” without explaining the transition can mislead readers dealing with a transfer occurring in Tax Year 2026-27.

For transactions completed before 1 April 2026, the old Act and its exemption conditions can continue to matter through the savings provisions. The Income Tax Department's transition FAQs specifically explain that if an exemption had already been claimed under an old provision such as Section 54 and a post-1 April 2026 event later violates the old lock-in condition, the new Act can tax the amount in the later tax year while the triggering condition and quantum remain linked to the old exemption framework.

Capital Gains Accounts Scheme (CGAS)

Where the relevant rollover provision requires investment by a specified return-filing cut-off and the money has not yet been fully used for purchase or construction, the unutilised amount may need to be deposited under the Capital Gains Accounts Scheme to preserve the exemption claim. Keeping the money in an ordinary savings account is not a substitute where the statutory provision requires CGAS.

The transition FAQs issued for the Income-tax Act, 2025 also address old CGAS deposits made before 1 April 2026. If such an amount later remains unutilised beyond the prescribed period, the new Act's transition provisions govern the year in which it becomes taxable while the old exemption conditions continue to determine the underlying breach.

Mutual funds: the reinvestment misconception

If you sell equity or mutual-fund units and immediately buy another mutual fund, that reinvestment does not automatically wipe out the gain. Capital gain is first computed on the original redemption or sale. Any exemption must come from a specific provision of law and its conditions. Merely keeping money invested in financial assets is not a general rollover exemption.

The same principle applies to switching between mutual-fund schemes. A switch can involve a redemption and fresh purchase for tax purposes. Do not assume that no tax event occurs merely because money did not come into your bank account.

Example 1: sale of residential house

Assume a taxpayer has a qualifying long-term gain of ₹30 lakh from a residential house transaction governed by the old Act and invests ₹24 lakh in another eligible residential house within the prescribed period. Subject to all conditions, the exemption is not automatically ₹30 lakh simply because another house was purchased. The eligible amount depends on the statutory computation and the qualifying investment.

Example 2: mutual-fund gain reinvested into another fund

A taxpayer sells equity mutual-fund units at a taxable gain and invests the entire sale proceeds in a different equity fund. The second investment does not itself exempt the first gain. The taxpayer must calculate the capital gain under the rules applicable to the first transfer and separately determine whether any specific rollover relief is available.

Example 3: old Section 54 claim and sale after 1 April 2026

Suppose a taxpayer sold an old residential house in March 2025, claimed exemption under Section 54 of the old Act and purchased a new house. If the new house is then sold after 1 April 2026 but within the old statutory lock-in period, the Income Tax Department's transition guidance explains that the consequences can arise in the later tax year under the Income-tax Act, 2025, while the old Section 54 conditions determine the violation and amount.

Common mistakes

• Using pre-23 July 2024 capital-gains rates for a later transfer.
• Assuming every reinvestment saves capital-gains tax.
• Confusing the residential-house rule with the rule for other long-term assets.
• Ignoring the 1 April 2026 transition to the Income-tax Act, 2025.
• Missing the purchase, construction or CGAS deadline.
• Assuming a mutual-fund switch is always tax-neutral.
• Claiming more exemption than the statutory cap or formula allows.
