A Bengaluru seller who booked a large profit on some shares in 2026 planned to roll it into a flat and pay no tax, assuming he only had to reinvest the gain. He was thinking of the wrong section. Under Section 54F, which applies to gains from assets other than a house, he had to reinvest the entire sale amount, not just the profit, to get the full exemption. That single misunderstanding is one of the most expensive tax mistakes a property buyer can make, and this piece exists to make sure you do not make it.

The short answer. Section 54 and Section 54F both let you avoid long term capital gains tax by buying a residential house, but they apply to different sales and demand different reinvestment. Section 54 covers the sale of a residential house and asks you to reinvest only the capital gain in a new house. Section 54F covers the sale of any other long term asset, like land, shares or gold, and asks you to reinvest the entire net sale consideration for a full exemption, with a proportionate benefit if you reinvest less. Both are capped at 10 crore rupees of exemption from 1 April 2023, both give you a window of one year before or two years after the sale to buy or three years to construct, and both lock the new house in for three years. Getting the section right is the difference between a full exemption and a surprise tax bill.

This is a buyer-side guide for Bengaluru. It explains each section, the crucial reinvestment difference, the timelines and the Capital Gains Account Scheme, and the honest traps to avoid.

What is the difference between Section 54 and 54F?

The distinction is entirely about what you sold. Section 54 applies when you sell a residential house and use the long term capital gain to buy or build another residential house. Section 54F applies when you sell some other long term asset, such as a plot of land, listed shares, mutual funds or gold, and put the proceeds into a residential house. In both cases the reward is the same, exemption from long term capital gains tax, but the route in differs because the asset you sold differs.

For a Bengaluru buyer this matters at the planning stage. If the money for your new flat is coming from selling an old flat, you are in Section 54 territory. If it is coming from selling land, equities or any non house asset, you are in Section 54F territory, and the rules you must follow are stricter about how much you reinvest.

Why does the reinvestment amount differ so much?

This is the single most important and most misunderstood point. Under Section 54, you only need to reinvest the capital gain, the profit, into the new house to shelter it fully. Under Section 54F, you must reinvest the entire net sale consideration, the whole amount you received, not merely the gain, to get the full exemption. If you reinvest only part of the net consideration under 54F, the exemption is proportionate, so you shelter only the fraction of the gain that matches the fraction of proceeds you reinvested.

The practical consequence is large. Sell a flat for 1 crore with a gain of 40 lakh, and under Section 54 you shelter the whole gain by reinvesting 40 lakh. Sell shares for 1 crore with the same 40 lakh gain, and under Section 54F you must reinvest the full 1 crore to shelter that gain completely. Confusing the two is exactly how buyers underinvest and get taxed.

What are the timelines and the 10 crore cap?

The timelines are common to both sections and unforgiving if missed. You must buy the new residential house within one year before or two years after the date of sale, or complete construction of a new house within three years of the sale. Miss these and the exemption is lost. Since 1 April 2023, the maximum exemption under either section is capped at 10 crore rupees, so gains beyond that ceiling are taxable even if fully reinvested, a change that mainly affects high value transactions.

There is also a lock in. You must not sell the new house for three years from its purchase or construction, because doing so rolls back the exemption you claimed, and the earlier sheltered gain becomes taxable. Treat the new home as a hold, not a flip, if you took the exemption.

What if you cannot reinvest before filing your return?

Property purchases rarely align neatly with tax deadlines, and the law anticipates this through the Capital Gains Account Scheme. If you have not used the money to buy or build by the due date for filing your income tax return, you can deposit the unutilised amount in a Capital Gains Account Scheme with a bank, which preserves your exemption while you complete the purchase.

1. Identify whether your sale falls under Section 54 or Section 54F before you plan.
2. For Section 54, earmark the capital gain for reinvestment in a house.
3. For Section 54F, earmark the entire net sale consideration, not just the gain.
4. Buy within one year before or two years after, or construct within three years.
5. If you cannot reinvest by the return due date, deposit in the Capital Gains Account Scheme.
6. Use the deposited amount within the two or three year window, or it becomes taxable.
7. Hold the new house for at least three years to keep the exemption.

Because the deposited money must be used within the specified period or it is taxed as a capital gain when the time limit expires, the scheme is a bridge, not a permanent shelter. For the mechanics, read our guide to the Capital Gains Account Scheme. And to understand the tax you are trying to avoid, see our overview of capital gains tax on selling property. When you reinvest into a specific Bengaluru home, such as Brigade Citrine, keep every payment record for your exemption claim.

What conditions can quietly disqualify you?

Both sections carry conditions that catch the unwary. Under Section 54F in particular, you generally should not own more than one residential house other than the new one on the date of the original sale, so a buyer who already holds several homes can lose the benefit. The exemption also unwinds if you sell the new house within three years, or if money parked in the Capital Gains Account Scheme is not used in time. And the reinvestment must go into a residential house, not commercial property or a plot with no construction, so buying bare land without building on it within the window does not qualify. Each of these is a common way a confident taxpayer trips up, which is why professional advice on a large gain is money well spent. It is also worth documenting everything from the outset. Keep the sale deed of the asset you sold, the purchase agreement and payment proofs of the new house, and any Capital Gains Account Scheme deposit receipts, because the tax department can question an exemption years later and a clean paper trail is what settles it. Buyers who treat the exemption as a filing formality rather than a documented plan are the ones who face notices, so build the file as you go rather than reconstructing it under pressure.

What is the honest limitation of these exemptions?

Sections 54 and 54F are powerful, but they are not a licence to buy carelessly. The exemption should follow a home you actually want, not push you into an overpriced flat just to shelter a gain, because a bad property decision can cost more than the tax you saved. The rules are also detail heavy, with strict timelines, reinvestment amounts, ownership conditions and a lock in, and a single slip can turn an expected zero tax outcome into a real bill. The disciplined approach is to identify the correct section early, plan the reinvestment amount precisely, use the Capital Gains Account Scheme if timing is tight, and take professional advice when the numbers are large. Used well, these sections let a Bengaluru buyer roll a gain into a home tax efficiently. Used carelessly, they become an expensive lesson in reading the fine print.

What is the main difference between Section 54 and 54F?

Section 54 applies when you sell a residential house and reinvest the capital gain in another house. Section 54F applies when you sell any other long term asset, like land or shares, and reinvest the entire net sale consideration in a house. The difference is that 54 needs only the gain reinvested, while 54F needs the whole sale amount.

Is there a cap on the capital gains exemption?

Yes. Since 1 April 2023, the maximum exemption under both Section 54 and Section 54F is capped at 10 crore rupees. Gains above that ceiling are taxable even if you reinvest the full amount, so the cap mainly affects high value property and asset sales. Below 10 crore, the usual reinvestment rules give the full exemption.

What is the time limit to buy a house for the exemption?

For both sections you must buy the new residential house within one year before or two years after the date of sale, or complete construction within three years of the sale. If you cannot reinvest by your income tax return due date, deposit the amount in the Capital Gains Account Scheme to preserve the exemption.

Can I lose the exemption after claiming it?

Yes. If you sell the new house within three years of buying or building it, the exemption is rolled back and the earlier gain becomes taxable. It can also be lost if money in the Capital Gains Account Scheme is not used in time, or, under Section 54F, if you own more than one other house on the sale date.
