| Most Indian families pay lakhs in capital gains tax on property sales without realising they could have saved it all — legally — under Section 54 |
You sold your house. The buyer paid you well. And then your CA drops the number — ₹8 lakh, ₹12 lakh, sometimes ₹20 lakh or more in long-term capital gains tax.
That is the moment most Indian families first hear about Section 54 of the Income Tax Act. The relief that lets you legally skip capital gains tax — entirely — if you buy or build another house within a specific window.
But here is the problem. Section 54 is not a blanket exemption. It comes with conditions that are easy to miss. The time limits are strict. The ₹10 crore cap introduced in Budget 2023 changed the game for high-value properties. And after Budget 2024 removed indexation for newer properties, the math itself has changed.
This guide covers every condition, every deadline, every calculation you need — verified against the Income Tax Department's own tutorials, CBDT circulars, and recent ITAT rulings from 2024 and 2025. Written for the person who is actually selling a house and needs to know exactly what to do.
What Is Section 54 of the Income Tax Act?
Section 54 is titled "Profit on sale of property used for residence." In plain language, it says this: if you are an individual or a Hindu Undivided Family, and you sell a residential house you have held for more than 24 months, and you use the profit to buy or construct another residential house in India — the government will not tax that profit.
The exemption is not automatic. You have to meet every condition. You have to buy or build within a specific time window. And if you cannot complete the reinvestment before your income tax return is due, you have to park the money in a Capital Gains Account Scheme (CGAS) to hold your claim.
Section 54 has existed for decades. But three recent changes have made it more complex than ever before — the ₹10 crore cap (Budget 2023), the removal of indexation and shift to 12.5% LTCG rate (Budget 2024), and the grandfathering provision that gives pre-July 2024 property owners a choice between two tax calculation methods.
All Conditions You Must Meet to Claim Section 54 Exemption
Every condition listed below must be satisfied simultaneously. Missing even one means the exemption is denied entirely.
Condition 1 — Who can claim: Only individuals and Hindu Undivided Families (HUFs). If you are a company, LLP, partnership firm, or trust, Section 54 does not apply to you.
Condition 2 — What you must sell: A long-term residential house property. "Long-term" means you held it for more than 24 months before selling. The income from this property should be chargeable under "Income from House Property." It does not matter whether the house was self-occupied or rented out — both qualify.
Condition 3 — What you must buy or build: One new residential house property located in India. The property must be residential — not commercial, not agricultural land, not a bare plot. If you buy a plot and construct a house on it within the deadline, that qualifies as "construction." But a plot sitting empty does not.
Condition 4 — The time window: You must purchase the new house within 1 year before or 2 years after the date of sale. If you are constructing, the deadline is 3 years from the date of sale. These are hard deadlines. Missing them by even a day means the exemption is gone.
Condition 5 — The ₹10 crore cap: From Assessment Year 2024-25 onwards, the maximum exemption under Section 54 is ₹10 crore. If your new house costs more than ₹10 crore, only ₹10 crore is considered for computing exemption. This was introduced by Finance Act 2023.
Condition 6 — The 3-year lock-in: You must not sell the new house within 3 years from the date of its purchase or completion of construction. If you do, the exemption you claimed earlier is fully reversed.
Condition 7 — CGAS deposit: If the full capital gain amount has not been reinvested before the due date for filing your income tax return (typically 31 July), you must deposit the unused amount in a Capital Gains Account Scheme account at an authorised bank. Without this deposit, the exemption is lost for the unreinvested portion.

Time Limits for Purchase and Construction — The Exact Deadlines
The time limits under Section 54 are non-negotiable. Here is the complete picture:
Purchase before sale: You can buy the new house up to 1 year before selling the old one. So if you sell on 15 July 2025, any house purchased between 16 July 2024 and 15 July 2025 qualifies.
Purchase after sale: You have 2 years from the date of sale. Using the same example, you can buy any time up to 15 July 2027.
Construction: You have 3 years from the date of sale. That gives you until 15 July 2028 in this example. This is the more generous window, and courts have consistently treated booking a flat in an under-construction building as "construction" — not "purchase" — which means you get the 3-year window instead of 2 years.
Compulsory acquisition cases: If the government acquired your property, the time period is counted from the date you actually receive compensation — not from the date of acquisition.
One practical point that people miss: courts have been lenient in cases where the buyer paid the full amount within the deadline but the builder delayed possession. In CIT vs R.L. Sood (Delhi High Court), the exemption was allowed because the assessee had paid the entire amount on time — the builder's delay was not held against the taxpayer.
How to Calculate Exemption Under Section 54 — With Examples
The exemption formula is straightforward: Exemption = the lower of your long-term capital gain, the cost of the new house, or ₹10 crore.
Let us walk through three real-world scenarios.
Example 1 — Full Exemption
Mr. Sharma bought a flat in 2012 for ₹35 lakh. He sells it in August 2025 for ₹1.3 crore. His LTCG, after indexation, comes to ₹54 lakh. He buys a new apartment for ₹70 lakh in January 2026.
Exemption = lower of ₹54 lakh (LTCG) and ₹70 lakh (new house cost) = ₹54 lakh. Taxable capital gain = zero. He pays no capital gains tax at all.
Example 2 — Partial Exemption
Mrs. Gupta sells her house for ₹2 crore. Her LTCG comes to ₹1.2 crore. She buys a smaller house for ₹75 lakh.
Exemption = lower of ₹1.2 crore and ₹75 lakh = ₹75 lakh. Taxable LTCG = ₹1.2 crore minus ₹75 lakh = ₹45 lakh. She pays tax on ₹45 lakh at the applicable rate.
Example 3 — The ₹10 Crore Cap in Action
Mr. Amir sells a large property in Mumbai for ₹18 crore. His LTCG is ₹13 crore. He buys a new house for ₹14 crore.
The new house costs more than ₹10 crore, so only ₹10 crore is considered. Exemption = lower of ₹13 crore (LTCG) and ₹10 crore (deemed cost of new house) = ₹10 crore. Taxable LTCG = ₹3 crore.
Budget 2024 Game-Changer — The 12.5% Rate and Indexation Removal
Budget 2024 (presented on 23 July 2024) changed how capital gains tax works on property sales in India. The old system charged 20% tax but let you adjust the purchase price for inflation (indexation). The new system charges only 12.5% but gives you no indexation benefit.
After significant public backlash, the government introduced a grandfathering provision on 6 August 2024. Here is how it works now:
Property bought before 23 July 2024 (by resident individuals and HUFs): You get a choice. Calculate your tax both ways — 20% with indexation, and 12.5% without indexation. Pay whichever is lower. This is a genuine advantage for people who bought property many years ago, where indexation significantly reduces the taxable gain. And if you are confused about which tax regime to file under, our guide on how to switch between old and new tax regime in India covers that in detail.
Property bought on or after 23 July 2024: Only the 12.5% without indexation option is available. No choice. No indexation.
NRIs get no choice: The grandfathering provision applies only to resident individuals and HUFs. NRIs selling property in India get only the 12.5% without indexation rate, regardless of when they bought the property.
Now here is the critical part: Section 54 exemption itself is completely unchanged. CBDT confirmed this explicitly in its FAQs dated 25 July 2024 — "No change in roll over benefits." You still get to claim Section 54, 54EC, 54F on top of whichever rate applies. The Budget changed the tax rate, not the exemption.
Should You Use Indexation or Not? A Quick Comparison
Consider a house bought in FY 2010-11 for ₹40 lakh, sold in FY 2025-26 for ₹1.5 crore. CII for 2010-11 is 167 and for 2025-26 is 376.
Option 1 — 20% with indexation: Indexed cost = ₹40 lakh × (376 ÷ 167) = ₹90.06 lakh. LTCG = ₹1.5 crore − ₹90.06 lakh = ₹59.94 lakh. Tax at 20% = ₹11.99 lakh. With 4% cess = ₹12.47 lakh.
Option 2 — 12.5% without indexation: LTCG = ₹1.5 crore − ₹40 lakh = ₹1.10 crore. Tax at 12.5% = ₹13.75 lakh. With 4% cess = ₹14.30 lakh.
In this case, the old method saves about ₹1.83 lakh. The longer you held the property and the more inflation has compounded, the more likely the 20% with indexation route wins. Run both calculations before filing.

| After Budget 2024, sellers of pre-July 2024 properties must run both calculations — 20% with indexation and 12.5% without — and pick whichever saves more tax |
Capital Gains Account Scheme (CGAS) — How It Works Step by Step
If you have not finished buying or building your new house before your ITR due date (31 July for most individuals), the law requires you to deposit the unused capital gain amount in a Capital Gains Account Scheme account. This is not optional — without this deposit, the exemption is denied for the unreinvested portion.
Where to open: Any authorised bank branch. All public sector banks offer CGAS. Since November 2025, the Finance Ministry has also authorised 19 private sector banks including ICICI Bank, HDFC Bank, Axis Bank, Kotak Mahindra Bank, and Federal Bank.
Two types of accounts: Type A works like a savings account — flexible withdrawals, lower interest. Best when you need to make staged payments to a builder during construction. Type B works like a fixed deposit — higher interest, but locked for a tenure. You must convert it to Type A before making withdrawals.
How to open: Visit the bank branch with your PAN, address proof, and photograph. Fill Form A in duplicate. Declare whether the funds will be used for purchase or construction — you cannot change this later. Deposit via cash, cheque, demand draft, UPI, NEFT, or RTGS.
How to withdraw: Submit Form C for the first withdrawal, Form D for subsequent ones. You must utilise the withdrawn amount within 60 days. For withdrawals above ₹25,000, payment to the seller or builder must be by demand draft or cheque.
What if you do not use the money in time: If the deposited amount is not utilised within the specified period (2 years for purchase, 3 years for construction), the unused amount is treated as LTCG of the financial year in which the deadline expires — not the year you originally sold the property. You will owe tax plus interest.
Interest on CGAS: The interest earned is taxable as "Income from Other Sources." It is not tax-free.
NRIs: Must open an NRO Capital Gains Account (not NRE). Subject to FEMA regulations.
Two-House Option — When You Can Buy Two Properties
Finance Act 2019 introduced a special provision: if your LTCG from the house sale does not exceed ₹2 crore, you can purchase or construct two residential houses instead of one and still claim full exemption.
There are two important catches. First, this is a once-in-a-lifetime option. You can use it only once across all your assessment years — never again. Second, the ₹2 crore limit refers to the capital gain amount, not the property cost. If your LTCG is even ₹1 above ₹2 crore, this option is not available.
One clarification people often get wrong: the once-in-a-lifetime restriction applies only to this two-house proviso. The regular Section 54 exemption for buying one house can be claimed multiple times in different years — there is no lifetime limit on that.
The 3-Year Lock-In — What Happens If You Sell the New House Early
If you sell the new house within 3 years of purchasing or completing construction, the entire Section 54 exemption you claimed earlier is reversed. The mechanics work like this:
The amount of exemption previously claimed is subtracted from the cost of acquisition of the new house. This artificially inflates your capital gain on the new house sale.
For example: You claimed ₹30 lakh exemption on the new house which cost ₹40 lakh. You sell the new house within 3 years for ₹55 lakh. Adjusted cost = ₹40 lakh − ₹30 lakh = ₹10 lakh. Short-term capital gain = ₹55 lakh − ₹10 lakh = ₹45 lakh, taxable at your income tax slab rate. That is a very expensive mistake.
Section 54 vs Section 54F vs Section 54EC — Which One Applies to You?
These three sections are often confused. Here is the clearest way to understand the difference:
Section 54 applies when you sell a residential house and buy another residential house. You need to reinvest only the capital gain amount. Available only to individuals and HUFs.
Section 54F applies when you sell any long-term capital asset other than a residential house — like shares, gold, commercial property, or land — and buy a residential house. The catch here is that you must reinvest the entire net sale consideration (not just the gain) for full exemption. Partial investment gives proportionate exemption. Also available only to individuals and HUFs who do not own more than one residential house on the date of transfer.
Section 54EC applies when you sell land or building and invest up to ₹50 lakh in specified bonds (NHAI, REC, PFC, IRFC) within 6 months. Available to everyone — individuals, HUFs, companies, firms. The bonds have a 5-year lock-in and currently pay about 5.25% interest (taxable).
Can you combine them? Yes. You can claim Section 54 and Section 54EC on the same property sale — invest part of the gain in a new house and part in bonds. You can also claim Section 54 and 54F in the same year for different assets sold. All caps operate independently.

Special Cases — NRIs, Inherited Property, Joint Ownership, Under-Construction Flats
NRIs Selling Property in India
NRIs can claim Section 54 with the same conditions as residents, but with additional complications. The buyer must deduct TDS at 12.5% plus surcharge and cess on the entire sale consideration — not just the gain. NRIs can apply for a lower TDS certificate using Form 13 to reduce this. The new house must be in India (post-2014 amendment). And critically, the grandfathering provision that lets residents choose between 20% with indexation and 12.5% without indexation is not available to NRIs. They get only the 12.5% without indexation rate.
Inherited or Ancestral Property
Section 54 is fully available when you sell inherited property. The cost of acquisition is deemed to be the cost at which the previous owner bought it. If the property was acquired before 1 April 2001, you can substitute the fair market value as on that date. The holding period includes the previous owner's period — so inherited properties almost always qualify as long-term. Indexation is calculated from the year the previous owner acquired the property, not from the date of inheritance.
Joint Ownership
Each co-owner computes their capital gains proportionate to their share. Each co-owner can independently claim Section 54 on their portion. ITAT Mumbai (April 2025) ruled that exemption cannot be denied merely because the new property was bought jointly with a spouse. Delhi High Court in CIT vs Kamal Wahal even allowed exemption when the new property was entirely in the spouse's name — though this is debated. Safest approach: keep the new property in the seller's own name or as joint owner.
Under-Construction Flats
Buying a flat in an under-construction building is treated as "construction" under Section 54 — not "purchase." This matters because you get the more generous 3-year construction deadline instead of the 2-year purchase deadline. The Bombay High Court in Mrs. Hilla J.B. Wadia and CBDT Circular No. 471 both confirm this position. If the builder delays possession beyond your control, courts have been lenient — provided you made the full payment within the time limit.
What the Courts Say — Key Rulings From 2024 and 2025
Saroj Rani vs ITO (ITAT Delhi, August 2025): A taxpayer bought seven adjacent units on the same floor of a building and used them as a single residence. The Assessing Officer allowed exemption for only one unit. ITAT overruled this and allowed full exemption of ₹2.22 crore, holding that all seven units together constituted "one residential house."
Nitin Bhatia vs ITO (ITAT Hyderabad, January 2026): The assessee did not deposit money in CGAS but did invest the full amount in a new house within the time limit. ITAT ruled that CGAS non-deposit is a procedural requirement, not a substantive one. Since the money was actually reinvested in time, exemption could not be denied. Substantive compliance trumps procedural lapse.
PCIT vs Lata Goel (Delhi HC, April 2025): The taxpayer bought an old house, demolished it, and constructed a new one on the same plot. The court allowed Section 54 exemption for the entire construction cost, confirming that "purchase and construction" need not be mutually exclusive.
Venkatraman Jayashree Priyadharshini (ITAT Chennai, 2025): Interior decoration expenses of ₹88.85 lakh — modular kitchen, wardrobes, electrical work — were allowed as part of the cost of the new house under Section 54. The test applied was "functional necessity" — expenses that make the house livable qualify.
Five Mistakes That Get Section 54 Claims Rejected
Mistake 1 — Missing the CGAS deposit deadline. Many people assume they can deposit in CGAS any time before buying the new house. Wrong. The deposit must be made before the ITR due date — 31 July of the assessment year. If you file a belated return in December but did not deposit in CGAS by 31 July, the exemption is lost for the unreinvested amount.
Mistake 2 — Buying property outside India. Since AY 2015-16, the new property must be in India. Buying a condo in Dubai or a house in the UK does not qualify. This catches NRIs off guard.
Mistake 3 — Buying a bare plot and not constructing. A plot of land alone does not qualify. You must construct a residential house on it within 3 years. If construction is not completed within the deadline, the entire exemption is reversed.
Mistake 4 — Selling the new house within 3 years. The lock-in is strict. If you sell the new house even at 2 years and 11 months, the full exemption is clawed back and added to your taxable income in the year of sale.
Mistake 5 — Confusing Section 54 and 54F investment requirements. Under Section 54, you need to invest only the capital gain. Under 54F, you must invest the entire sale consideration. Many people invest just the gain amount when claiming 54F, then get a proportionate exemption instead of full — and face a surprise tax demand.

Frequently Asked Questions
Can I claim Section 54 exemption every year?
Yes. There is no lifetime limit on the regular Section 54 exemption. You can claim it every time you sell a residential house and buy another — as long as all conditions are met each time. The once-in-a-lifetime restriction applies only to the two-house option (where LTCG is within ₹2 crore).
Is Section 54 available under the new tax regime?
Yes. Section 54 capital gains exemptions are available under both the old and new income tax regimes. Capital gains are taxed at special rates regardless of which regime you choose for your regular income.
Can I take a home loan and still claim Section 54?
Yes. There is no restriction on funding the new house through a home loan. The exemption is based on the cost of the new house, not the source of funds. You can use part sale proceeds and part loan — the full cost of the new house counts for exemption calculation.
What if my builder delays possession beyond 3 years?
Courts have generally been lenient. In CIT vs R.L. Sood (Delhi HC), exemption was allowed when the buyer had paid the full consideration within the time limit but the builder delayed handover. The key is proving that the delay was not in your control and you made the full payment within the deadline.
Can I claim Section 54 if I already own other houses?
Yes. Unlike Section 54F, Section 54 has absolutely no restriction on the number of houses you already own. You can own five houses and still claim Section 54 when selling the sixth and buying a seventh.
What happens if I deposit in CGAS but do not use the money?
The unutilised amount is treated as LTCG of the financial year in which the time limit expires. For example, if you sold in April 2025 and the 3-year construction deadline lapses in April 2028 (FY 2028-29), the unutilised CGAS amount becomes taxable as LTCG in FY 2028-29 — not in FY 2025-26 when you originally sold.
Bottom Line
Section 54 remains the single most effective way to legally eliminate capital gains tax on residential property sales in India. The law is generous if you follow its conditions precisely — but it punishes mistakes harshly.
The three things that matter most: buy or build within the deadline (1 year before or 2 years after for purchase, 3 years for construction), deposit in CGAS if you cannot complete the investment before 31 July, and do not sell the new house within 3 years.
If your capital gain is large enough that splitting between a house and bonds makes sense, combine Section 54 with Section 54EC. If you are selling commercial property instead, look at Section 54F. And if your property was bought before July 2024, run both tax calculations — 20% with indexation and 12.5% without — to find the lower amount.
The rules are all there. The deadlines are clear. The only real risk is not knowing about them in time.
