If you have made a long-term capital gain and want to avoid paying tax on it, the Income-tax Act gives you three main exemption routes: Section 54, Section 54F and Section 54EC. They sound similar, but they are not interchangeable. Picking the wrong one is one of the most common and most expensive mistakes I see, because the choice is usually made after the sale, when your options have already narrowed.
Here is the one-line rule of thumb before we go deeper. Sold a residential house and buying another house? Section 54. Sold something else (a plot, shares, gold) and buying a house? Section 54F. Do not want to buy a house at all? Section 54EC bonds, up to Rs. 50 lakh. This article walks through exactly when each one applies, the conditions that trip people up, and a worked example for each so you can see the numbers.
Section 54: house sold, house bought
Section 54 applies when you sell a long-term residential house (held for more than 24 months) and reinvest the capital gain in another residential house in India. Note the crucial detail: under Section 54 you only need to reinvest the gain, not the whole sale value. That is what makes it the most generous of the three.
The reinvestment window is one year before the sale or two years after it for a purchase, and three years for construction. You can also, once in your lifetime, split the gain across two houses provided the total capital gain does not exceed Rs. 2 crore.
There is a ceiling to be aware of. From AY 2024-25, the maximum exemption under Section 54 is capped at Rs. 10 crore. If your new house costs more than that, the exemption stops at Rs. 10 crore and the balance gain is taxable.
Worked example
Say you sell a flat and your long-term capital gain works out to Rs. 80 lakh. You buy a new flat for Rs. 60 lakh. Since the amount reinvested (Rs. 60 lakh) is less than the gain (Rs. 80 lakh), you get exemption of Rs. 60 lakh, and the remaining Rs. 20 lakh is taxed at 12.5%, i.e. Rs. 2.5 lakh (plus cess). Had you bought a house costing Rs. 80 lakh or more, the entire gain would have been exempt.
Section 54F: any asset sold, house bought
Section 54F is the route when you sell a long-term capital asset other than a residential house — a plot of land, listed or unlisted shares, gold, a commercial property — and invest in a residential house. The catch that surprises people is that here you must reinvest the entire net sale consideration, not merely the gain, to get a full exemption. If you invest only part of it, the exemption is proportionate:
Exemption = Capital Gain × (Amount invested in new house ÷ Net sale consideration)
Section 54F also carries an ownership condition that Section 54 does not. On the date of transfer you must not own more than one residential house (other than the new one), and you must not buy another house within two years or construct one within three years — otherwise the exemption is withdrawn. The Rs. 10 crore ceiling applies here too.
Worked example
You sell a plot for a net consideration of Rs. 1 crore, on which your long-term capital gain is Rs. 60 lakh. You invest Rs. 70 lakh of the proceeds into a house. Your exemption is not Rs. 60 lakh — it is proportionate: Rs. 60 lakh × (70 ÷ 100) = Rs. 42 lakh. The remaining Rs. 18 lakh of gain is taxable. To have exempted the whole Rs. 60 lakh, you would have needed to invest the full Rs. 1 crore net consideration in the house.
Section 54EC: no house, just bonds
Section 54EC is for people who have a gain on land or building (or both) and do not want to lock their money into another property. Instead you invest the gain in specified capital-gains bonds — issued by REC, NHAI, PFC or IRFC — within six months of the sale.
Three limits define this route. First, the maximum you can invest is Rs. 50 lakh, and this cap runs across the financial year of transfer and the subsequent financial year combined — you cannot split Rs. 50 lakh in March and another Rs. 50 lakh in April to double it. Second, the bonds are locked in for five years. Third, the interest (currently around 5.25% per annum) is fully taxable as income from other sources, and the PSUs do not deduct TDS on it for residents, so you must report it yourself each year.
Section 54EC is best thought of as a partial tool. If your gain is Rs. 40 lakh, you can shelter all of it. If your gain is Rs. 1.2 crore, bonds alone can only cover Rs. 50 lakh; the rest needs Section 54/54F or simply paying the tax.
Side-by-side comparison
| Feature | Section 54 | Section 54F | Section 54EC |
|---|---|---|---|
| Asset sold | Residential house (long-term) | Any long-term asset except a house | Land or building (or both), long-term |
| Invest in | Residential house | Residential house | REC / NHAI / PFC / IRFC bonds |
| Amount to reinvest | The capital gain | The entire net sale consideration | The gain, capped at Rs. 50 lakh |
| Time limit | Buy: 1 yr before / 2 yrs after; Build: 3 yrs | Same as Section 54 | 6 months from sale |
| Exemption | Full (up to cost / Rs. 10 cr cap) | Proportionate (full only if all proceeds invested) | Amount invested, max Rs. 50 lakh |
| Lock-in / holding | New house: 3 years | New house: 3 years + ownership condition | Bonds: 5 years |
The deadline trap: parking money in CGAS
For both Section 54 and Section 54F, the reinvestment often cannot be completed before your income-tax return is due (31 July for most individuals). The law anticipates this. If you have not bought or constructed the new house by the ITR filing due date, you must deposit the unutilised amount in a Capital Gains Account Scheme (CGAS) account with a bank before that date, and then use it within the two/three-year window. Miss this step and the exemption is lost even if you genuinely intended to reinvest. Section 54EC has no CGAS route — the six-month bond deadline is hard.
Which one should you actually pick?
If you sold a house and are buying a house, Section 54 is almost always best because you only reinvest the gain. If you sold a non-house asset and are buying a house, Section 54F is your route — but plan to deploy the whole sale value, not just the profit. If you want liquidity, no property hunt, and your gain is within Rs. 50 lakh, Section 54EC bonds are the clean answer despite the modest 5.25% return and five-year lock-in. Large gains often need a combination: bonds for Rs. 50 lakh and a house for the rest.

Key takeaways
- Section 54 = house to house; reinvest only the gain; Rs. 10 crore cap.
- Section 54F = any other long-term asset to a house; reinvest the entire net sale consideration or the exemption is proportionate; you cannot already own more than one other house.
- Section 54EC = land/building gain into REC/NHAI/PFC/IRFC bonds within 6 months; maximum Rs. 50 lakh across the year of sale and the next; 5-year lock-in.
- If you cannot reinvest before your ITR due date, deposit the amount in a Capital Gains Account Scheme account to preserve the 54/54F exemption.
- Bond interest under 54EC is fully taxable and not subject to TDS for residents, so report it yourself every year.
Frequently Asked Questions
Can I claim Section 54 and Section 54EC together on the same house sale?
Yes. If you sell a residential house, you can invest part of the gain in a new house under Section 54 and part in bonds under Section 54EC (up to Rs. 50 lakh). This is a common way to shelter a large gain fully.
Does the new house have to be in India?
Yes. For both Section 54 and Section 54F, the reinvestment must be in a residential house situated in India. A property purchased abroad does not qualify.
What happens if I sell the new house within three years?
The exemption you claimed is reversed. For Section 54/54F, if you sell the new house within three years, the earlier exempted gain is brought to tax by reducing the cost of the new house. For 54EC, redeeming or transferring the bonds within five years makes the exempted gain taxable in the year of transfer.
Is the Rs. 50 lakh 54EC limit per property or per person per year?
It is effectively per person and capped at Rs. 50 lakh across the financial year of transfer and the immediately following financial year taken together. You cannot invest Rs. 50 lakh in each of two consecutive years for the same gain to get Rs. 1 crore of exemption.
I only own one house and I am selling shares — can I use Section 54F?
Yes. Owning one house (other than the one you are buying) is permitted under Section 54F. The bar is on owning more than one other residential house on the date of transfer. Selling long-term shares and buying a house is a textbook Section 54F case.
