Property Sale Tax Calculator
The only asset where the law lets you compute the tax twice and pay the lower — 12.5% flat or 20% with indexation, if you qualify.
What the Property sale tax calculator does
A property sale tax calculator computes long-term gains both ways. A resident individual selling property acquired before 23 July 2024 pays the lower of 12.5% without indexation and 20% with it. Sections 54, 54F and 54EC can remove the gain — but only if the money is committed by the filing date.
Property is the one asset where the law lets you compute the tax twice
The Finance (No. 2) Act 2024 replaced 20%-with-indexation on long-term property gains with a flat 12.5% and no indexation. For anything held a long time through high inflation that was a large increase, and the Act was amended before it passed to give the old route back as an option.
A resident individual or HUF selling land or a building acquired before 23 July 2024 works the tax out both ways and pays the lower. A non-resident does not get it, a company does not, and property bought on or after that date does not.
⚠️ The relief only reduces tax — it cannot create a loss. Where indexing the cost takes the gain below zero the bill is nil, and there is still nothing to carry forward.

Your inputs
The financial year of purchase, which sets the Cost Inflation Index for the indexed route.
Long-term treatment begins at 24 months. The index is only notified up to 2025-26.
What you originally paid.
Structural additions, not repairs or maintenance. Indexed alongside the cost.
What the buyer actually pays you.
If this exceeds the sale price by more than 10%, section 50C taxes you on it instead.
Expenditure wholly and exclusively in connection with the transfer. Deductible under section 48.
Who is selling?
Only the first group gets the choice between the two routes.
What did you sell?
A house sold and reinvested in a house gets section 54. Anything else gets 54F, which is proportionate rather than rupee for rupee.
Bought one year before or two years after, or built within three. A deposit in a Capital Gains Account Scheme counts too.
Was that money committed by the return due date?
This is the trap. An intention is not enough — unspent gain must sit in a CGAS account before you file, or the exemption is gone.
NHAI or REC bonds, five-year lock-in, capped at ₹50,00,000 across the whole transfer.
Your income tax slab
Only used where the gain is short-term, which is charged at your slab rather than at a fixed rate.

Both routes, computed — and the flat one wins
Indexing raises your cost by the movement in the Cost Inflation Index, which shrinks the gain — but the rate on it is 20% rather than 12.5%. Which way that lands depends on how long you held and how much the property actually appreciated.

What this assumes
- Whole years, taken at mid-year. Purchase and sale are placed in June of the years you selected, which fixes the financial year for the index cleanly. A real sale turns on actual dates, and a property held close to 24 months needs its real dates rather than a slider.
- Only notified index values are used. The Cost Inflation Index runs to 2025-26 here. A later year is reported as uncomputable rather than estimated, because a guessed index would produce a confident wrong number.
- Improvements are indexed with the cost. Strictly each improvement is indexed from the year it was incurred. This page indexes it alongside the purchase, which understates the indexed cost where the work was done much later — that is, it errs towards showing more tax rather than less.
- Section 54 conditions are not tested. The ₹10,00,00,000 ceiling is applied, but the page does not check how many other houses you own, which 54F requires, nor the three-year lock-in that claws the exemption back if the new house is sold too soon.
- A resident seller, and one property. A non-resident seller faces withholding under section 195 at the full rate rather than 1% under 194-IA, which applies above ₹50,00,000. Jointly held property is apportioned between owners and is not modelled. Surcharge is excluded throughout.

How the property sale tax calculation works
LTCG = net consideration − cost. Tax = LOWER of 12.5% flat and 20% on the indexed gain, for a resident individual on property bought before 23 July 2024.
Land and buildings turn long-term at 24 months. Below that the whole gain is short-term and charged at the seller's slab rate. Above it, the Finance (No. 2) Act 2024 set a flat 12.5% with no indexation, replacing the 20%-with-indexation regime — a large increase for anything held a long time through high inflation, which is why the Act was amended before it passed to hand the old route back as an option. A resident individual or HUF selling property acquired before 23 July 2024 computes the tax both ways and pays the lower. A non-resident does not get the choice, a company does not, and property bought on or after that date does not. The relief has a limit that is easy to miss: indexation can reduce the tax to nil but cannot manufacture a loss, so a negative indexed gain leaves nothing to set off or carry forward. The comparison must be made after the exemptions rather than before, because an exemption is a flat rupee amount and therefore strips proportionally more out of the smaller indexed gain — a property on which the flat route was cheaper with no reinvestment can become cheaper on the indexed route once a reinvestment is made. Section 50C substitutes the stamp duty value for the stated consideration wherever it exceeds it by more than 10%, so the gain is computed on money that never changed hands, and the buyer is charged on the same difference under section 56(2)(x) at the same time — one understated price, taxed twice, once on each side. The reinvestment exemptions are section 54 for a residential house reinvested in a residential house, capped at ₹10 crore; section 54F where something other than a house was sold, which is proportionate to the share of net consideration reinvested rather than rupee for rupee; and section 54EC for up to ₹50 lakh in NHAI or REC bonds within six months, with a five-year lock-in. All of them turn on a filing deadline standing in front of the two-year purchase window: any gain not yet spent must sit in a Capital Gains Account Scheme deposit by the date the return is due, and missing that forfeits the exemption entirely even where the house is bought a month later well inside the period the section otherwise allows. The buyer withholds 1% under section 194-IA above ₹50 lakh of consideration, computed on the substituted value where 50C applies; a non-resident seller faces the much larger withholding under section 195 instead.
Frequently asked questions
What is the tax on selling property in India?
Held over 24 months, the gain is long-term. The Finance (No. 2) Act 2024 set the rate at 12.5% without indexation, but a resident individual or HUF selling property acquired before 23 July 2024 may instead compute it at 20% with indexation and pay whichever is lower. Held 24 months or less, the whole gain is short-term and charged at your slab rate.
Should I choose 12.5% without indexation or 20% with it?
Neither is generally better — it depends on how long you held and how much the property actually appreciated. A long hold through high inflation with modest appreciation usually favours indexation, because indexing the cost shrinks the gain more than the higher rate costs you. Rapid appreciation over a short period usually favours the flat 12.5%. Compute both; the law lets you take the lower.
Who gets the choice between the two rates?
Resident individuals and HUFs only, and only on land or buildings acquired before 23 July 2024. A non-resident does not get it, a company does not, and property bought on or after that date does not. There is also a limit worth knowing: indexation can take the tax to nil but cannot create a loss you carry forward. It gives you a better bill, not a better position.
What is section 50C?
Where the stamp duty value exceeds the stated sale price by more than 10%, section 50C substitutes the stamp duty value as your sale consideration — so you are taxed on money that never changed hands. The buyer is charged on the same difference under section 56(2)(x) at the same time, which means a single understated price is taxed twice, once on each side. The two sections were written to work together.
How can I avoid tax on a property sale?
By reinvesting. Section 54 exempts the gain on a residential house reinvested in another residential house, capped at ₹10 crore. Section 54F does the same where you sold something other than a house, but proportionately — the exemption is the gain scaled by the share of net consideration you reinvested. Section 54EC exempts up to ₹50 lakh invested in NHAI or REC bonds within six months, with a five-year lock-in.
What is the Capital Gains Account Scheme and why does it matter?
It is the trap that catches most people. Section 54 gives you a year before and two years after to buy, or three to build — but any gain you have not yet spent must be deposited in a Capital Gains Account Scheme account by the date your return is due. Miss that date and the exemption is lost entirely, even if you buy the house a month later well inside the two-year window. An intention buys no exemption.
Does the buyer deduct TDS when I sell property?
Yes, 1% under section 194-IA where the consideration is ₹50 lakh or more, and it follows the stamp duty value where section 50C has substituted it. That is for a resident seller. If you are a non-resident the buyer must deduct under section 195 instead, at the full applicable rate plus surcharge and cess — a much larger sum, recoverable only by filing an Indian return.
