Section 54 can reduce tax on long-term capital gains from selling a qualifying residential house when an eligible taxpayer reinvests in another home. Under the familiar rule, an individual or Hindu undivided family (HUF) can buy one residential house in India within one year before or two years after the sale, or construct one within three years after it. The section number depends on the law governing the transfer: the corresponding residential-house rule appears as Section 82 in the Income-tax Act, 2025, so check the applicable tax year and transition rules before relying on a section number.
The relief is generally limited to the lower of the eligible gain and the qualifying cost of the replacement home, with a ₹10 crore cost cap under Section 82. A one-time option to invest in two homes is available when the gain does not exceed ₹2 crore. These are rules for a qualifying home sale—not a general exemption for every kind of asset sale.

What is the Section 54 exemption?
Section 54 is the familiar name for a tax relief under the Income-tax Act, 1961. It applies when an eligible taxpayer earns long-term capital gains from transferring a qualifying residential house and reinvests in a replacement home within specified time limits. Instead of requiring reinvestment of the entire sale proceeds, the rule links the relief to the eligible capital gain and the qualifying cost of the new home.
The law’s numbering has changed in the Income-tax Act, 2025: the corresponding residential-house provision is Section 82, titled “Profit on sale of property used for residence.” That Act also has a Section 86, but it addresses gains from a long-term asset other than a residential house when the proceeds are invested in a home. Section 86 is not simply a new number for Section 54; the eligibility rules and calculation differ. The official 2025 Act text is the primary source for Section 82. The Income Tax Department’s Section 54 explanation describes the familiar 1961 Act framework and states that it reflects amendments through the Finance Act, 2026.

For a real sale, do not assume that the older or newer number applies based only on when you read this article. The relevant transfer year and transition provisions determine which Act governs; the sources cited here do not establish the answer for every transaction.
Who can claim relief, and what kind of property qualifies?
The claimant must be an individual or a Hindu undivided family (HUF), and the gain must be long-term capital gain from a qualifying residential house. The replacement must generally be one residential house in India, subject to the limited two-house election.
- Eligible taxpayer: an individual or HUF.
- Original asset: a residential house comprising a building or buildings and appurtenant land, with income chargeable under the head “Income from house property.”
- Type of gain: long-term capital gain, as classified under the law for the relevant transfer year.
- Replacement: a residential house in India, purchased or constructed within the permitted period.
The sources establish “long-term” as the test but do not support a single holding-period number for every transfer year. Confirm the classification under the law applicable to your sale rather than assuming a period from a different year or asset type.
This distinction matters if you sold something other than a home. Reinvesting gains from another kind of long-term asset in a residential house is a different relief: the legacy provision is Section 54F, while the 2025 Act places the corresponding rule in Section 86. Do not apply Section 54’s home-sale formula to that case.

What are the purchase and construction deadlines?
For the legacy Section 54 framework, the replacement home must be purchased within one year before or two years after the original home’s transfer, or constructed within three years after the transfer. The Income Tax Department’s capital-gains overview and Section 54 material describe these windows; Section 82 contains the corresponding rules in the 2025 Act.
| What you do | Permitted window | How to count it |
|---|---|---|
| Purchase a replacement home | One year before to two years after transfer | Use the transfer date of the original property as the reference point. |
| Construct a replacement home | Within three years after transfer | Construction must fall within the statutory period after the original transfer. |
A purchase made before the sale can qualify if it falls within the one-year look-back window. A purchase made after the sale has a longer window than construction. Do not treat the deadlines as interchangeable, or assume that depositing money extends them.
How much of the gain can be exempt?
The relief is limited by both the eligible capital gain and the qualifying cost of the replacement home. Under Section 82, the portion of new-home cost above ₹10 crore is ignored for this purpose, and gains above ₹10 crore are also excluded from the amount considered under the deposit provision.
As a simplified illustration, if an eligible gain is ₹1.2 crore and the qualifying replacement-home cost is ₹90 lakh, the cost ceiling means relief cannot exceed ₹90 lakh. If the qualifying cost is at least as large as the eligible gain, the gain ceiling means the relief cannot exceed the gain. This illustrates the limits, not a full tax calculation: the taxpayer’s transfer year, cost facts, and applicable law still matter.

In particular, this home-sale relief does not generally require reinvesting all sale proceeds. It concerns eligible capital gain and qualifying replacement-home cost. That differs from rules for certain other assets, where the amount that must be invested may be measured differently.
Can the gain be invested in two homes?
Yes, but only in a narrow case. If the capital gain does not exceed ₹2 crore, the taxpayer may elect to purchase or construct two residential houses in India instead of one. Section 82(5) states this option, and the Income Tax Department’s 2026 material gives the ₹2 crore threshold.

The election can be used only once. After exercising it, the taxpayer cannot use the two-house option again for that or another tax year. The option does not remove the other conditions: the claimant must still qualify, the homes must be in India, the transaction must meet the relevant timing rules, and the exemption remains subject to statutory limits. If the gain exceeds ₹2 crore, the two-home election is not available under this rule.
What if the gain has not been reinvested by the return-filing deadline?
If the qualifying gain remains unutilised by the applicable return-filing stage, the taxpayer may need to deposit the unutilised amount under the notified Capital Gains Account Scheme (CGAS). Under Section 82, the deposit must be made before filing the return and no later than the applicable due date under section 263(1), with proof submitted with the return.

- Work out what remains unused. Identify the eligible gain not yet applied to the qualifying purchase or construction.
- Check the return deadline that applies to you. Section 82 ties the deposit deadline to the applicable due date under section 263(1); do not substitute a generic calendar date.
- Deposit under the notified scheme before filing. A deposit made after the return is filed does not meet the stated sequence.
- Submit proof with the return. The statute requires proof of the qualifying deposit to accompany the return.
- Complete the purchase or construction on time. A CGAS deposit preserves the treatment of the qualifying amount under the statutory rules; it does not create an unlimited extension of the purchase or construction window.
The amount already used for the replacement home plus a qualifying deposit is treated as new-home cost, subject to the statutory rules and caps. If the deposited amount is not fully used within the applicable three-year period, the statute brings the corresponding unused amount into tax in the tax year that period expires, under its prescribed calculation. The Department’s Section 54 tutorial also explains the legacy framework and cautions readers to verify the Act, rules, and notifications.
What can reverse the relief later?
Claiming the exemption is not always the end of the tax question. A later sale, certain additional home purchases or construction, or failure to use a CGAS deposit in time can make some or all of the previously untaxed gain taxable.
- Early transfer of the replacement home: if it is transferred within three years after purchase or construction, gains previously not charged become long-term capital gains in the tax year of that transfer.
- Certain additional residential houses: purchasing or constructing specified additional houses within the statutory windows can cause previously untaxed gains to become taxable.
- Unused CGAS balance: an amount not applied within the permitted three-year period is brought into tax under the statutory calculation when that period expires.
These are later events affecting relief already claimed, not just conditions to check on the original return. The exact amount brought into tax depends on the statutory calculation and the taxpayer’s facts; do not assume that every later event has the same result.

Before claiming relief, assemble the transaction facts and match them to the law for the transfer year. The available official material explains the rules, but it does not resolve the 1961-to-2025 Act transition for every sale. A year-specific review is especially important when the original transfer, home purchase, construction, or return deadline falls near a change in law.

- Identify the transfer year and applicable Act. Confirm whether the legacy Section 54 or Section 82 framework governs the transaction, including any relevant transition provisions.
- Confirm taxpayer and asset eligibility. Check that the claimant is an individual or HUF and that the gain arises from a qualifying long-term residential house.
- Map the dates. Compare the transfer date with the purchase date or construction period; if using CGAS, also record the deposit and return-filing dates.
- Compare gain and qualifying cost. Apply the lower-of-gain-or-cost principle, the ₹10 crore cap, and any other statutory limitation relevant to the year.
- Decide whether the two-home election is available. Check the ₹2 crore threshold and whether the one-time election has already been used.
- Track later conditions. Keep the replacement home’s purchase or construction date and monitor any later transfer, additional-home event, or unused deposit.
Because the result depends on transfer-year law, filing deadlines, ownership and cost facts, a tax professional can help verify the applicable section and computation. The Income Tax Department’s official materials are useful starting points, but they are not a substitute for checking the governing Act and notifications for an individual transaction.
Frequently Asked Questions
Does the Income Tax Department’s Section 54 page settle which Act applies to my sale?
No. The Department describes that page as reflecting the legacy 1961 Act framework, while the 2025 Act places the corresponding residential-house rule in Section 82. The applicable Act for a specific transfer depends on the relevant tax year and transition rules.

Section 82 requires proof of the qualifying deposit to be submitted with the return. The precise documents and account details should be checked against the notified scheme and rules applicable to the return; the section summary alone does not specify a complete document checklist.
Does Section 54 cover gains from selling a plot or commercial property?
The rule discussed here is for a qualifying residential house, not every property or long-term asset. Reinvesting gains from another type of long-term asset in a home falls under a different provision, so the asset and applicable year’s law need to be checked before choosing a relief.
