Saving Tax on a Property Sale: Section 54, 54F and 54EC Bonds Explained

Selling a property at a profit doesn't have to mean a large tax bill. Three reinvestment exemptions — Section 54, Section 54F and Section 54EC bonds — can reduce your long-term capital gains tax, often to zero. Here's how each one works, the deadlines that trip people up, and how to combine them. Updated for the Income-tax Act, 2025, which renumbered these sections from 1 April 2026.

The Short Version

• Section 54 (now Section 82): Sell a residential house, buy or build another residential house in India, and the reinvested gain is exempt — up to ₹10 crore.
• Section 54F (now Section 86): Sell any long-term asset other than a residential house — a plot, commercial property, shares, gold — and buy or build a residential house. You must reinvest the sale proceeds, not just the gain, to get the full exemption.
• Section 54EC (now Section 85): Sell land or a building and invest the gain in specified capital gain bonds within 6 months — up to ₹50 lakh, locked in for 5 years.
• All three apply only to long-term gains — for land and buildings, that means you held the property for more than 24 months.
• Deadlines are strict. Missing a 6-month bond window or a 2-year purchase window by even a day typically means losing the exemption.
• If you haven't reinvested by your return filing deadline, park the money in a Capital Gains Account Scheme (CGAS) account to keep the house-purchase exemptions alive.
• The exemptions can be combined. A common approach is a new house under Section 54 plus bonds under Section 54EC for any leftover gain.

A Note on Section Numbers

The Income-tax Act, 2025 replaced the Income-tax Act, 1961 from 1 April 2026. The capital gains exemptions were renumbered, but their conditions, timelines, and limits carried over.

Most people, advisers, and bond issuers still use the old numbers, so this guide uses both. For sales made on or after 1 April 2026, your return will reference the new section numbers.

The Three Exemptions at a Glance

Section 54 (Now Section 82): Selling a House to Buy a House

This is the most widely used exemption, designed for people moving from one home to another.

Who can use it

• Individuals and HUFs only
• The property sold must be a residential house — a flat, independent house, or villa — held for more than 24 months
• The house can be self-occupied or let out

What you must do

Invest the capital gain in one residential house in India, either by:

• Buying it within 1 year before or 2 years after the date of sale, or
• Constructing it within 3 years after the date of sale

A house purchased abroad doesn't qualify.

How much is exempt

The exemption is the lower of:

• the long-term capital gain, and
• the amount invested in the new house

— subject to an overall cap of ₹10 crore. If the new house costs more than ₹10 crore, the excess isn't counted.

So if your gain is ₹80 lakh and the new house costs ₹1.2 crore, the full ₹80 lakh is exempt. If the new house costs ₹60 lakh, ₹60 lakh is exempt and ₹20 lakh remains taxable (unless you use Section 54EC for it — see below).

The two-house option

If your capital gain does not exceed ₹2 crore, you can choose to invest in two residential houses instead of one. This option can be used only once in your lifetime — once exercised, it isn't available on any future sale.

The 3-year lock-in

If you sell the new house within 3 years of buying or constructing it, the exemption you claimed is effectively reversed: the exempted amount is reduced from the new house's cost when computing the gain on its sale, which usually increases your tax on that sale.

Practical points

• Timelines run from the date of transfer, which for most sales is the date the sale deed is registered. Confirm the exact date with your CA.
• Under-construction purchases: Buying a flat from a developer is often treated as construction, so the 3-year window applies. Make sure possession — or at least substantial completion — falls within 3 years.
• Buying in your own name is the safest route. Purchasing the new house solely in a spouse's or child's name has led to disputes over eligibility.
• Funding with a home loan: The test is that you invest the required amount in a new house within the window. Tribunals have generally accepted purchases funded partly by loans, but keep clear documentation of the timeline and payments.

Section 54F (Now Section 86): Selling Something Else to Buy a House

Section 54F covers the reverse situation: you sell an asset that isn't a residential house, and use the money to buy one. For property owners, this most commonly applies to the sale of a residential plot, agricultural land that is a capital asset, or commercial property — and it also applies to shares, mutual funds, gold, and other long-term assets.

Who can use it

• Individuals and HUFs only
• The asset sold must be a long-term capital asset other than a residential house

The key difference from Section 54: invest the whole sale proceeds

Under Section 54F, to get a full exemption you must invest the entire net sale consideration — the sale price minus transfer expenses — not just the gain.

If you invest less, the exemption is proportional:

Exemption = Capital gain × (Amount invested in new house ÷ Net sale consideration)

The ownership conditions

Section 54F has conditions that Section 54 doesn't:

• On the date of sale, you must not own more than one residential house other than the new one. Owning one house already is fine; owning two or more generally disqualifies you.
• Within 2 years after the sale, you must not buy another residential house (other than the new one), and within 3 years you must not construct one. Doing so withdraws the exemption.
• If you sell the new house within 3 years, the exemption is withdrawn and taxed as long-term capital gain in the year you sell.

Timelines and cap

• Buy 1 year before or 2 years after the sale, or construct within 3 years
• Cost of the new house is counted up to ₹10 crore

Example

You sell a residential plot for a net ₹1.5 crore. It cost you ₹50 lakh, so your long-term capital gain is ₹1 crore. You buy a flat for ₹1.2 crore.

Exemption = ₹1 crore × (₹1.2 crore ÷ ₹1.5 crore) = ₹80 lakh

₹20 lakh of the gain remains taxable. Had you invested the full ₹1.5 crore in the flat, the entire ₹1 crore gain would be exempt.

Section 54EC (Now Section 85): Capital Gain Bonds

Section 54EC is the option for sellers who don't want to buy another property — or whose gain exceeds what they're reinvesting in a house.

Who can use it

• Any taxpayer — individuals, HUFs, companies, firms, and others
• Only for long-term capital gains on land, a building, or both. Gains on shares, gold, or other assets don't qualify.

What you must do

Invest the capital gain in specified bonds within 6 months of the date of sale.

Limits and lock-in

• Maximum ₹50 lakh. This cap applies to the combined investment made in the financial year of the sale and the following financial year — so you can't get around it by splitting the investment across two years.
• 5-year lock-in. The bonds can't be redeemed, transferred, or used as security for a loan during this period. Doing any of these withdraws the exemption.
• No CGAS option. Unlike Sections 54 and 54F, there's no way to extend the 6-month deadline by depositing the money in a Capital Gains Account Scheme.

The bonds themselves

Issuers reset the rate on new issues from time to time, so confirm the current rate before investing.

The trade-off

Section 54EC bonds offer safety and an immediate tax saving, but a modest, fully taxable return and no access to your money for five years. The decision is usually straightforward when you compare the tax saved (12.5% of the gain, or more if you'd otherwise have paid under the older 20%-with-indexation route) against the opportunity cost of locking up the money at 5.25% pre-tax.

The Capital Gains Account Scheme: Your Safety Net

For Sections 54 and 54F, the deadlines for buying or constructing a house often run past your income tax return filing date. The Capital Gains Account Scheme (CGAS) bridges that gap.

How it works:

1. Before your return filing due date for the year of sale, deposit the amount you intend to reinvest (the gain for Section 54; the net sale consideration for Section 54F) in a CGAS account with an authorised bank branch.
2. Claim the exemption in your return based on the deposit.
3. Withdraw from the account to pay for the new house within the allowed window.
4. If you don't use the money for a house within the time limit (2 years for purchase, 3 years for construction), the unutilised amount becomes taxable as long-term capital gain in the year the period expires.

Deposits can be kept in a savings-type or term-deposit-type account. Withdrawals are allowed only for the purpose of buying or constructing the new house.

Bottom line: If you're planning to buy a house but haven't done so by your filing deadline, a CGAS deposit is essential. Without it, the exemption is lost for the amount not yet invested.

Combining the Exemptions

You don't have to choose just one. Common combinations:

Section 54 + Section 54EC (selling a house)

Invest part of the gain in a new house and the rest in bonds.

Example: You sell a flat bought in FY 2016-17 for ₹90 lakh at ₹1.8 crore — a long-term gain of ₹90 lakh. At 12.5%, that would mean ₹11.25 lakh in tax (plus cess).

• You buy a new flat for ₹70 lakh within 2 years → ₹70 lakh exempt under Section 54
• You invest ₹20 lakh in capital gain bonds within 6 months → ₹20 lakh exempt under Section 54EC

Taxable gain: nil.

Section 54F + Section 54EC (selling a plot or commercial property)

Invest part in bonds and part in a house. Because Section 54F is calculated on the net sale consideration, the interaction between the two needs care — the amount you invest in bonds and the amount you invest in the house both affect how much of the gain remains taxable. Have your CA model this before committing funds.

Using the two-house option

Example: You sell a house with a long-term gain of ₹1.8 crore. Because the gain is under ₹2 crore, you can choose to invest in two flats — say, ₹1 crore and ₹80 lakh — and claim the full ₹1.8 crore as exempt under Section 54. Remember this is a once-in-a-lifetime choice.

How This Fits With the 12.5% vs 20% Choice

Since 23 July 2024, long-term gains on property are taxed at 12.5% without indexation. Resident individuals and HUFs selling land or a building acquired before that date can instead choose 20% with indexation if it results in lower tax.

If you have that choice, the exemptions apply to each computation separately. Because the taxable gain is different under each method, the amount you need to reinvest to fully exempt the gain can also differ. When planning a reinvestment, run both computations — including the reinvestment — and choose the combination that minimises total tax.

Common Mistakes That Cost Sellers the Exemption

1. Missing the 6-month bond deadline. Section 54EC has no extension and no CGAS option. Count from the date of transfer, not the date you receive the money.
2. Not depositing in CGAS before filing. If you haven't bought the new house by your return due date, the uninvested amount must be in a CGAS account — otherwise the exemption is lost.
3. Buying the new house too early. Section 54 and 54F allow purchase up to 1 year before the sale — not earlier.
4. Investing only the gain under Section 54F. Section 54F requires the net sale consideration for full exemption. Investing just the gain gives only partial relief.
5. Owning too many houses for Section 54F. Owning more than one residential house (besides the new one) on the date of sale generally disqualifies you.
6. Selling the new house within 3 years. This reverses the exemption.
7. Taking a loan against 54EC bonds. Pledging or transferring the bonds within 5 years withdraws the exemption.
8. Exceeding ₹50 lakh in bonds across two years. The cap covers the year of sale and the following year combined.
9. Buying a house abroad. Only a residential house in India qualifies.
10. Getting the holding period wrong. None of these exemptions apply to short-term gains. Confirm you've held the property for more than 24 months.

For NRI Sellers

NRIs can claim Sections 54, 54F and 54EC on the same terms as residents, provided the new house is in India. Two practical points:

• TDS: When an NRI sells property, the buyer must deduct TDS on the capital gain. If you plan to reinvest and claim an exemption, apply for a lower or nil deduction certificate before the sale — otherwise you'll need to claim a refund when filing.
• Rate choice: NRIs are taxed at 12.5% without indexation on long-term gains, with no option to use 20% with indexation.

Pre-Sale Planning Checklist

1. Confirm the holding period — more than 24 months for land and buildings.
2. Identify which exemption fits: selling a house (Section 54), selling a plot or other asset (Section 54F), or preferring not to buy property (Section 54EC).
3. For Section 54F, check how many residential houses you own on the planned sale date.
4. Calculate the gain — under both the 12.5% and 20%-with-indexation methods if you qualify for the choice.
5. Map the deadlines from the expected registration date: 6 months for bonds; 2 years to buy or 3 years to build a house.
6. Decide the split between a new house and bonds.
7. If the house purchase will extend beyond your filing deadline, plan a CGAS deposit.
8. For NRIs, apply for a lower TDS certificate before the sale.
9. Have a chartered accountant review the plan before you sign the sale deed.

Frequently Asked Questions

Q: What's the difference between Section 54 and Section 54F? Section 54 applies when you sell a residential house; you need to reinvest the capital gain. Section 54F applies when you sell any other long-term asset, such as a plot or commercial property; you need to reinvest the entire net sale consideration for a full exemption, and there are additional conditions on how many houses you own.

Q: Can I claim both Section 54 and Section 54EC on the same sale? Yes. A common approach is to invest part of the gain in a new house and the balance in capital gain bonds, subject to each section's conditions and the ₹50 lakh bond cap.

Q: What is the maximum I can invest in 54EC bonds? ₹50 lakh, counting investments made in the financial year of the sale and the following financial year together.

Q: What interest do 54EC bonds pay? As of mid-2026, the prevailing rate on new issues is 5.25% per annum, paid annually. The interest is fully taxable. Confirm the current rate before investing, as issuers revise it periodically.

Q: What if I haven't bought the new house by the time I file my return? Deposit the amount in a Capital Gains Account Scheme account before your return filing due date, then use it to buy or build within the allowed time. If you don't use it in time, the unused amount becomes taxable.

Q: Can I use Section 54 to buy two houses? Yes, once in your lifetime, if the capital gain doesn't exceed ₹2 crore.

Q: Is there a limit on the Section 54 exemption? Yes. The exemption is capped at ₹10 crore.

Q: Do these exemptions still exist under the new Income-tax Act, 2025? Yes. Section 54 is now Section 82, Section 54EC is now Section 85, and Section 54F is now Section 86. The conditions, timelines, and limits carried over.

Q: Can NRIs claim these exemptions? Yes, provided the new residential house is in India. NRIs should also plan for TDS by applying for a lower deduction certificate before the sale.

Final Word

For most property sellers, capital gains tax is not a fixed cost — it's a planning problem. Reinvesting in another home through Section 54 or 54F, parking the balance in 54EC bonds, and using a CGAS account to bridge the timeline can often bring the tax to zero.

What catches people out is rarely the concept; it's the calendar. The 6-month bond window, the 2- and 3-year house windows, the return filing deadline for CGAS, and the 3- and 5-year lock-ins all need to be mapped out before you sign the sale deed. Plan the sequence first, get a CA to confirm it, and the exemption takes care of itself.
