Capital gains tax on property sale

How it works

We calculate your gain as sale price minus purchase price and costs. Long-term gains, where you held the property for more than 24 months, are taxed at 12.5 percent without indexation under current rules. Short-term gains are added to your income and taxed at your slab. Exemptions under sections 54, 54F and 54EC can reduce the tax; consult a chartered accountant.

How the gain is worked out

The gain is your sale price minus what you originally paid, minus the costs you are allowed to deduct. Those deductible costs are worth taking seriously because they directly reduce the taxable gain: brokerage on the sale, the stamp duty and registration you paid when buying, legal fees, and the cost of capital improvements you made to the property. Routine repairs and repainting are not improvements; an added floor or a new structure generally is.

Keep the receipts. In practice the difference between a well-documented cost base and a poorly documented one is a real tax difference, and it is decided years before you sell.

Long-term or short-term

For immovable property, holding for more than 24 months makes the gain long-term. At or below 24 months it is short-term, and short-term gains are simply added to your income and taxed at your applicable slab rate, which is why this tool cannot show a short-term tax figure: it depends on your total income for the year, not on the property alone.

The 2024 change, and why your purchase date matters

Long-term capital gains on property are taxed at 12.5 percent without indexation under the current rules, and that is what this calculator applies. There is an important exception: for property acquired before 23 July 2024, you may instead compute the tax under the older method of 20 percent with indexation, and pay whichever of the two is lower.

This tool does not compute the indexation route, because doing so requires the Cost Inflation Index for the relevant years and the choice interacts with your wider tax position. If you bought before that date, treat the figure here as one of two possibilities and have a chartered accountant compute both. For an older property bought cheaply and held a long time, indexation can make a substantial difference.

Ways the liability can be reduced

The Income Tax Act provides reliefs where the proceeds are reinvested, each with its own conditions, caps and time limits. In outline:

• Section 54, where the gain from selling a residential house is reinvested in another residential house within the prescribed period
• Section 54F, where the gain from selling a capital asset that is not a residential house is invested in one
• Section 54EC, where the gain is invested in specified bonds within a limited window after the sale, subject to a cap

These are genuinely useful and genuinely technical. Deadlines are strict, the conditions matter, and getting the sequence wrong can forfeit the relief entirely. This is the clearest case on our site for paying a professional rather than relying on a calculator.

What this estimate excludes

• Surcharge and cess, which apply on top of the tax shown
• The 20 percent with indexation alternative, as explained above
• Any exemption under sections 54, 54F or 54EC
• Tax deducted at source on the sale consideration, which applies above a threshold and is adjusted against your final liability
• Set-off of capital losses from other assets

Frequently asked questions

Does indexation still exist?

Only as the alternative computation available for property acquired before 23 July 2024, where you may pay the lower of 12.5 percent without indexation or 20 percent with it. For property acquired after that date, the 12.5 percent route applies.

Can I avoid the tax by buying another house?

Potentially, under Section 54, if the reinvestment meets the conditions and timelines. It is a deferral mechanism with rules, not an automatic exemption, and unspent proceeds may need to be parked in a capital gains account scheme before the filing deadline. Take advice before you commit the money.

What counts as an improvement cost?

Capital improvements that add to the property, such as constructing an additional floor or a substantial extension. Maintenance, repainting and routine repairs generally do not qualify. Documentation is what makes a claim stand up.
