When you sell a house, flat or plot in India for more than it cost you, the profit is a capital gain and the Income Tax Act expects a slice of it. How much you pay turns on one thing above all — how long you held the property before selling. Get the holding period and the reinvestment rules right and a large part of the tax can legitimately disappear; miss them and you hand over far more than you needed to. This guide explains how the gain is computed, the long-term and short-term distinction, the headline 2026 rate, and the exemptions under Sections 54 and 54EC that let you keep the money working. It matters most when you eventually exit a long-term hold — a point we return to with Godrej Brooklyn Avenue as an example. Figures are accurate as of 2026; always verify on the income tax portal before you file.

How a Capital Gain Is Calculated

The taxable gain is not simply your sale price. It is the net sale consideration minus three things: the cost of acquisition (what you originally paid), the cost of improvement (any capital additions you made, such as an extension or a major renovation), and the expenses of transfer (brokerage, legal fees and stamp paper on the sale). What remains is the capital gain that the tax is charged on. Keeping clean records of the purchase deed, improvement bills and brokerage invoices directly lowers the figure the tax applies to, so those documents are worth filing away from day one.

Long-Term vs Short-Term: The Holding Period

For immovable property, the dividing line is twenty-four months. Hold the property for more than 24 months and the profit is a Long-Term Capital Gain (LTCG). Sell within 24 months and it is a Short-Term Capital Gain (STCG), which is added to your total income and taxed at your normal slab rate — for someone in the top bracket that can mean 30% plus surcharge and cess. Long-term gains enjoy a concessional flat rate instead, which is why timing a sale just past the two-year mark can change the tax materially.

Type of Gain	Holding Period	Tax Rate (2026)
Short-Term Capital Gain (STCG)	24 months or less	Added to income, taxed at your slab rate
Long-Term Capital Gain (LTCG) — transfers on/after 23 July 2024	More than 24 months	12.5% without indexation
LTCG — grandfathering option (property bought before 23 July 2024)	More than 24 months	20% with indexation, if it works out lower

The Key 2026 Rule: 12.5% Without Indexation

The big change to be aware of concerns transfers made on or after 23 July 2024. For these, long-term capital gains on property are taxed at a flat 12.5% without the benefit of indexation. Indexation was the old mechanism that inflated your purchase cost by a cost-inflation index, shrinking the taxable gain; the new flat rate drops that step but charges a lower headline percentage. There is an important relief built in: if the property was bought before 23 July 2024, you may choose between the new 12.5% without indexation and the older 20% with indexation, and pay whichever produces the lower tax. For older properties with a long holding period, indexation can still win, so it is worth computing both. As of 2026, verify on the income tax portal before locking in your choice.

A Worked Example

Suppose you bought a flat for ₹1.20 crore and sell it five years later for ₹2.10 crore. Ignoring small transfer costs, the long-term capital gain is roughly ₹2.10 Cr − ₹1.20 Cr = ₹90 lakh. Under the post-July-2024 rule, the tax is 12.5% of ₹90 lakh, which is about ₹11.25 lakh (plus applicable surcharge and 4% cess). Now apply Section 54: if you reinvest that gain into one new residential house in India within the prescribed window, the capital gain becomes exempt. Reinvest the full ₹90 lakh into a new home and the ₹11.25 lakh tax is wiped out entirely. Reinvest only part of it and the exemption is proportionate — the unreinvested portion stays taxable at 12.5%.

Saving the Tax: Section 54 and Section 54EC

Section 54 is the workhorse exemption for individuals selling a residential house. Reinvest the long-term capital gain into one residential house in India and the gain is exempt to the extent reinvested. The window is specific: you must buy the new home one year before or two years after the sale, or construct it within three years of the sale. Buying a second home elsewhere or holding the proceeds in cash does not qualify — the reinvestment has to be a residential property.

Section 54EC offers a different route. You can invest the long-term gain — up to a ceiling of ₹50 lakh — into specified bonds issued by the NHAI or REC within six months of the sale, and that amount becomes exempt. These bonds carry a lock-in, so the money is parked for a fixed term, but it is a clean way to shelter a gain when you do not want to buy another house. If you have not reinvested before your return-filing due date, you can deposit the unutilised gain in a Capital Gains Account Scheme account with a bank, which preserves the exemption while you complete the purchase or construction within the allowed period. Pairing this with the rules in our guide to rental income tax for landlords gives you a fuller picture of the tax life-cycle of a property you hold and later sell.

What This Means for a Godrej Brooklyn Avenue Buyer

Godrej Brooklyn Avenue is an under-construction development by Godrej Properties in Kukatpally, west Hyderabad, RERA Telangana registered as P02200010981, offering 3 and 4 BHK homes priced between ₹2.10 crore and ₹4.40 crore, with possession scheduled for June 2031. Capital gains tax does not apply while you simply own and hold the apartment — it is triggered only on the day you sell. Treated as a long-term hold, a resale several years after possession would attract LTCG at the prevailing rate, and a well-planned Section 54 reinvestment into your next home could neutralise much of that tax. It is worth remembering that buying the property has its own statutory layer too; our note on TDS on property purchase in Hyderabad covers the deduction the buyer handles at the purchase end, and the broader investment guides set the resale maths in context.
