A Bengaluru family selling a flat they bought fifteen years ago in Marathahalli to fund a larger home in 2026 discovers that the gain, the difference between what they paid and what they now receive, is itself taxable. On a property that has multiplied in value, that capital gains tax can run into many lakhs, enough to change what they can afford next. The good news is that the law offers two clean, legal ways to reduce or even eliminate it, provided the seller plans before signing, not after.

The short answer. Long-term capital gains on a Bengaluru property held for more than 24 months are taxed in 2026 at 12.5 percent without indexation, though owners who bought before 23 July 2024 can instead choose 20 percent with indexation if that works out lower. You can legally reduce the tax to nil by reinvesting the gain in another residential house under Section 54, or up to 50 lakh rupees of it in specified bonds under Section 54EC. The trade-off is liquidity and lock-in: both routes require you to park the money rather than spend it freely.

Quick facts for July 2026: property held over 24 months qualifies for long-term treatment, the headline long-term rate is 12.5 percent without indexation with a grandfathered 20 percent-with-indexation option for older acquisitions, and the relief provisions sit in the Income Tax Act administered by the Income Tax Department. Given the 2024 change, confirm your exact position with a chartered accountant.

How is capital gains tax on property calculated in 2026?

Capital gains tax applies to the profit on sale, not the whole sale price, and the rate depends on how long you held the property. If you held it for more than 24 months it is a long-term capital asset, taxed at 12.5 percent without indexation in 2026; if you held it for 24 months or less the gain is short term and added to your income, taxed at your slab rate. For properties acquired before 23 July 2024, you may choose the older method of 20 percent with indexation where that produces a lower tax, a transitional relief worth checking.

The gain itself is the sale consideration minus your cost of acquisition and the cost of any improvements, plus eligible transfer expenses like brokerage. This is exactly why the value you recorded when you bought matters so much: a higher recorded purchase cost means a smaller taxable gain today. Under-declaring on the way in quietly enlarges the tax on the way out, the mirror image of the stamp duty temptation.

How does Section 54 let you avoid the tax?

Section 54 exempts your long-term gain to the extent you reinvest it in another residential house in India. If you buy the new home within one year before or two years after the sale, or construct one within three years, the gain used for that purchase is exempt from tax. Reinvest the entire gain and your capital gains tax on the old flat can fall to zero, which is why so many Bengaluru owners sell and buy in the same window when upgrading.

There are guardrails. The exemption covers one residential house, with a limited one-time option to use two houses where the gain is modest, and it is capped for very large gains. If you have not bought or built by the time you file your return, you must park the unused gain in a Capital Gains Account Scheme deposit to preserve the exemption. Miss the timelines or spend the money elsewhere, and the exemption is withdrawn and the tax revives.

What is the Section 54EC bond route?

Section 54EC lets you exempt long-term gains by investing them, within six months of the sale, in specified bonds issued by government-backed entities, up to a ceiling of 50 lakh rupees. The bonds carry a five-year lock-in and a modest fixed rate of interest, so this route suits a seller who does not want to buy another property immediately but still wants to shelter the gain. It is the natural choice when you are selling to free up cash rather than to upgrade your home.

The trade-offs are the cap and the lock-in. You can shelter at most 50 lakh rupees of gain this way, so a very large gain is only partly covered, and your money is tied up for five years at an interest rate below what equities or even some deposits might return. For a seller with a gain under the cap and no immediate property plan, though, 54EC is a simple way to convert a tax bill into a five-year investment.

Section 54 or 54EC: which should a Bengaluru seller choose?

Choose Section 54 if you are genuinely buying another home, and Section 54EC if you are not. The two are not mutually exclusive, and a seller with a large gain often uses both: reinvesting part in a new house under 54 and up to 50 lakh rupees in bonds under 54EC to cover the rest. The right mix depends on how much of the proceeds you need to live on versus reinvest, and on whether your next move is a bigger home or simply cash.

The table below compares the routes so you can see the trade-offs at a glance. Weigh them against your own plan, because the cheapest tax outcome is worthless if it locks up money you actually need. If part of your reason to sell is to clear a loan, our comparison of home loan prepayment versus investing the money is a useful companion read.

Treat the table as a map of options, then confirm the exact figures for your case with a tax professional, because the 2024 rate change makes the arithmetic less obvious than it used to be.

What records should a seller keep to prove the cost?

Keep everything that establishes your cost of acquisition and improvement, because that cost is what shrinks your taxable gain. That means the original sale deed and its stamp duty value, receipts for major improvements such as construction or substantial renovation, and proof of transfer expenses like brokerage on the current sale. Without these, you may be taxed on a larger gain than you actually made.

Clean title records serve double duty here, both to satisfy your buyer and to support your cost claim, which is why maintaining documents like the mother deed matters, as we set out in our guide to a property title search and the mother deed in Bengaluru. Good record-keeping through the years of ownership is quietly one of the most valuable tax habits a property owner can build.

A seven-point capital gains checklist for sellers

1. Confirm your holding period, since over 24 months means long-term treatment and a lower rate.
2. Compute the gain as sale value minus cost of acquisition, improvement and transfer expenses.
3. If you bought before 23 July 2024, compare 12.5 percent without indexation against 20 percent with indexation.
4. Decide early whether you will reinvest in a house under Section 54 or in bonds under Section 54EC.
5. Respect the timelines: two years to buy or three to build for Section 54, six months for 54EC bonds.
6. Park any unused gain in a Capital Gains Account Scheme deposit before you file if you have not reinvested.
7. Keep all cost and improvement records, and confirm the final position with a chartered accountant.

Plan these before you sign the sale deed and the tax becomes a decision you control rather than a bill you receive. The sellers who overpay are almost always those who closed the sale first and asked about capital gains afterwards, by which time several of these options had already lapsed.

How much is long-term capital gains tax on property in 2026?

Long-term capital gains on property held over 24 months are taxed at 12.5 percent without indexation in 2026. Owners who acquired the property before 23 July 2024 may instead opt for 20 percent with indexation where that results in a lower tax. Short-term gains, on property held 24 months or less, are added to income and taxed at your slab rate rather than a special rate.

Can I avoid capital gains tax by buying another house?

Yes, through Section 54. If you reinvest your long-term gain in another residential house, buying within two years or constructing within three, the reinvested gain is exempt, and reinvesting the whole gain can reduce the tax to nil. If you have not bought or built by the time you file, park the unused gain in a Capital Gains Account Scheme deposit to keep the exemption alive.

What is the limit under Section 54EC bonds?

Section 54EC lets you invest long-term capital gains, up to 50 lakh rupees, in specified government-backed bonds within six months of the sale to claim exemption. The bonds carry a five-year lock-in and a modest fixed interest rate. Because the cap is 50 lakh, a larger gain is only partly sheltered this way, so sellers with big gains often combine 54EC with a Section 54 reinvestment.

Is capital gains tax charged on the sale price or the profit?

On the profit, not the sale price. The taxable gain is your sale consideration minus your cost of acquisition, the cost of improvements and eligible transfer expenses such as brokerage. This is why keeping records of what you paid and spent is so valuable: a well-documented higher cost reduces the taxable gain, while missing records can leave you taxed on more than you actually earned.
