Selling property: how to reinvest and save tax

The tax you are trying to reduce

A property sale has two possible tax bills, depending on how long you held it.

Held 24 months or less, the gain is short-term and is simply added to your income, taxed at your slab rate.

Held longer than 24 months, it is long-term, and the rules since the July 2024 Budget are:

Cess of 4%, and surcharge at higher incomes, sits on top of all of these.

Which of the two routes is cheaper depends on how much the property gained. Take a flat bought for ₹50 lakh in 2015-16 and sold for ₹1.5 crore in 2026-27. The Cost Inflation Index is 254 for 2015-16 and 384 for 2026-27, so the indexed cost is about ₹75.6 lakh.

Here the flat 12.5% wins. Indexation wins only with a long holding and modest appreciation; roughly, the indexed gain has to be below 62.5% of the un-indexed one. The property capital gains calculator works out both routes and shows the cheaper one.

Before either, check the sale price. If the stamp duty value of the property is more than 110% of the price you actually receive, the stamp duty value is treated as the sale price. You can also deduct brokerage and other transfer costs from the gain, and add the cost of improvements to your cost.

The point that sizes everything else

The indexation choice limits the tax; it does not change the gain. The gain used for reinvestment, for setting off losses and for carry-forward is always the un-indexed one. In the example above, a seller who picked the indexed route would still need to reinvest against a ₹1 crore gain, not ₹74.4 lakh, to shelter all of it. Property gains after indexation explains why.

Three ways to reinvest

The Income-tax Act 2025 renumbered the reinvestment sections but kept their rules. The three that matter to most sellers:

Another house (section 82). Buy within one year before or two years after the sale, or finish building within three years. Invest the whole gain and the whole gain is exempt; invest part and that part is exempt. Once in a lifetime, a seller whose gain is ₹2 crore or less can spread it across two houses instead of one. Sell the new house within three years and the exemption is reversed.

Bonds (section 85). The issuers are government-backed entities such as REC, PFC and IRFC. The bonds must be bought within six months of the sale, are locked for five years, and pay interest that is fully taxable. The ₹50 lakh cap is shared across the year of sale and the following year, so you cannot split a large gain across two years to buy ₹1 crore.

A house from another asset (section 86). This is for a plot, shares, gold or any long-term asset other than a house. The exemption is in proportion to how much of the net sale proceeds you reinvest, not the gain, so sheltering all of it means putting the entire proceeds into the house. It is not available if, on the date of sale, you already own more than one residential house other than the new one.

The routes can be combined. A seller with a ₹1.2 crore gain on a flat could put ₹50 lakh into bonds and ₹70 lakh towards a new flat, and owe nothing.

If the house is not bought yet

Your return for the year of sale is due well before the two- or three-year window closes. Money you plan to spend on a house but have not spent by the return's due date must go into the Capital Gains Account Scheme at an authorised bank first. The deposit counts as invested. If you then do not use it within the window, the unused amount is taxed as a capital gain in the year the window ends.

Is reinvesting the right call?

The exemption saves tax, but each route puts the money somewhere you may not have chosen otherwise. Bonds lock it for five years at a taxable coupon. A second house is a large, illiquid, usually leveraged holding in one city.

Paying the 12.5% and keeping the rest free is a real option, not a failure. Sell a ₹1.5 crore flat with a ₹1 crore gain and the tax is ₹13 lakh including cess (more if surcharge applies, which it will once total income passes ₹50 lakh); roughly ₹1.37 crore is left to invest as you like. Whether a second property beats that depends on rent, upkeep and growth, and the rent vs buy calculator is the honest way to test it. If what you want is property exposure without owning a flat, REITs and InvITs are the listed option.

The buyer will also deduct TDS from what they pay you: 1% when the price is ₹50 lakh or more and you are resident, and much more if you are a non-resident. How NRI taxation works on Indian investments covers the NRI case. TDS is only a prepayment; your actual tax is settled in the return.
