LTCG at 12.5% on Property After the 2024 Regime Change

If you're preparing to sell a property you've owned for years, you've probably run into two conflicting headlines: "capital gains tax on property cut to 12.5%" and "sellers lose indexation, may pay more tax." Both are technically true, and the confusion is exactly why so many sellers delay running their own numbers until the sale deed is already in front of them. This guide walks through what actually changed on 23 July 2024, how to compute your tax both ways, and how to tell — with a calculator, not a guess — which route leaves more money in your pocket.

What Changed on 23 July 2024, and Why

Before the 2024 Budget, long-term capital gains (LTCG) on the sale of land and buildings were taxed at 20% after adjusting the cost of acquisition for inflation using the Cost Inflation Index — a process called indexation. Indexation effectively reduced your taxable gain by inflating your original purchase cost to today's rupee terms, which mattered a lot for older properties bought when prices (and the rupee's value) were very different.

From 23 July 2024 onward, the default regime changed: long-term capital gains on property are now taxed at a flat 12.5% without indexation. But the government also built in a grandfathering option: for land and buildings acquired before 23 July 2024, resident individuals and HUFs can choose whichever computation results in lower tax — the new 12.5% flat rate (no indexation) or the old 20% rate (with indexation). This choice is exactly why you can't simply believe either headline in isolation; the right answer depends entirely on your specific acquisition cost, acquisition date, and how much the property has appreciated.

It's worth being precise about scope here: whichever route you choose sits on top of, not instead of, the reinvestment exemptions under Section 54 and Section 54F — those still apply to reduce or eliminate the computed gain if you reinvest in a qualifying replacement house, regardless of which rate regime you used to arrive at the gain figure.

Step-by-Step: Computing Tax Both Ways

To compare the two routes for a property acquired before 23 July 2024, you need four numbers: your sale price, your original cost of acquisition, your acquisition year (to apply the correct Cost Inflation Index), and the Cost Inflation Index for the year of sale.

1. Compute the 12.5% no-indexation route. Taxable gain = sale price minus original cost of acquisition (and cost of any improvements), with no inflation adjustment. Tax = 12.5% of that gain.
2. Compute the 20% with-indexation route. Indexed cost of acquisition = original cost × (Cost Inflation Index of sale year ÷ Cost Inflation Index of acquisition year). Taxable gain = sale price minus this indexed cost. Tax = 20% of that gain.
3. Compare the two tax figures. Whichever is lower is the route you're entitled to choose, for properties acquired before the 23 July 2024 cut-off.
4. Layer in reinvestment exemptions. Once you know your computed gain under the chosen route, check whether reinvesting under Section 54 (house-to-house) or Section 54F (other asset to house) reduces your final liability further.
5. Check the cut-off date carefully. If your property was acquired on or after 23 July 2024, the choice doesn't apply — you're on the 12.5% no-indexation rate by default.

12.5% No-Index vs 20% With-Index: A Worked Example

Take a seller with a computed Rs 90 lakh gain on a straightforward no-indexation basis, and walk through how indexation might change that number depending on how old the acquisition is.

The table's message is simple: indexation's value depends entirely on how much time — and inflation — has passed since you bought the property, and how much the CII has moved between your acquisition year and your sale year. There's no universal winner; you must compute both for your specific numbers.

Geographic and Demographic Specifics: Old vs New Acquisition Dates

The 23 July 2024 cut-off means your acquisition date, not your city, is the primary variable that determines whether you even get a choice. That said, city context still shapes how the two routes typically play out:

• Older, low-cost-of-acquisition properties — the classic example being a flat bought in Bengaluru around 2005, when prices were a fraction of today's — tend to favor indexation, because the Cost Inflation Index adjustment shrinks the taxable gain substantially when the gap between acquisition year and sale year is large.
• Recently bought or high-appreciation properties — for instance, a flat bought in 2021 in a fast-appreciating micro-market — often favor the 12.5% flat rate, because indexation has had less time to compound, so the indexed cost doesn't shrink the taxable gain by much, and the flat 12.5% rate on the larger gain ends up lower than 20% on an only-slightly-smaller indexed gain.
• Cities where NHB RESIDEX data (Q4 FY25) shows the sharpest recent price appreciation — Bengaluru at roughly 13.1% year-on-year and Kolkata around 9.6% — are exactly the markets where this old-vs-new distinction has the biggest rupee impact, since a bigger absolute gain magnifies the difference between the two computation methods.

Mini Scenario: A 2005 Bangalore Flat vs a 2021 Purchase

Seller A bought a Bangalore flat in 2005 for a relatively low price and sells it in 2026 at a substantial gain. Because two decades of inflation have passed, the Cost Inflation Index adjustment inflates their original cost dramatically, shrinking the taxable gain under the indexation method. For this seller, the 20%-with-indexation route is likely to compute to a lower absolute tax bill than the 12.5% flat rate on the full, non-indexed gain — but this must be verified with the actual CII figures for 2005 and 2026, not assumed.

Seller B bought a flat in the same city in 2021 and sells it in 2026 at a strong but shorter-horizon gain. With only five years between acquisition and sale, the CII adjustment moves the cost basis only modestly, so the indexed gain isn't much smaller than the non-indexed gain. For this seller, the 12.5% flat rate on the larger, non-indexed gain is more likely to result in lower tax than 20% on a barely-reduced indexed gain.

The lesson from both sellers: run the actual arithmetic rather than assuming either regime is universally better. A property held two decades tends to favor indexation; a property held five years often favors the flat rate — but "tends to" and "often" are not substitutes for computing your own two numbers.

How Section 54/54F Still Apply After Picking the Rate

Choosing between 12.5% and 20% only determines how your gain is taxed — it doesn't change whether you can avoid that tax altogether by reinvesting. If you're selling a residential house and reinvesting in another one, Section 54 lets you exempt the gain (computed under whichever rate route you chose) by reinvesting in a new residential house within the statutory timelines, subject to the Rs 10 crore cap that has applied since assessment year 2024-25. If you're selling a different long-term asset and reinvesting in a house, Section 54F is the relevant provision instead. In both cases, you compute your gain under the rate regime that benefits you first, and then apply the reinvestment exemption to that computed figure — the two decisions are sequential, not either/or.

Pro Tips

• Always compute both routes using the actual Cost Inflation Index figures for your specific acquisition and sale years — don't rely on a rule of thumb like "always choose indexation for old properties," since the CII table doesn't move in a straight line every year.
• Factor in the cost of any capital improvements to the property (with their own indexation, if using that route) — many sellers under-report their true cost basis by forgetting renovation or structural-improvement costs.
• If you're close to the 23 July 2024 acquisition cut-off, verify your exact registration date on the sale deed or allotment letter — being on the wrong side of that date by even a few days removes the choice entirely.
• Model the after-tax proceeds under both routes in financial planning before you finalize your sale price negotiations, so your reinvestment budget reflects reality rather than a guess.
• Keep your original purchase deed, improvement invoices, and CII reference tables together in one file — this comparison is exactly the kind of computation a tax officer may ask you to justify years later.

Common Mistakes to Avoid

• Assuming indexation is always the better choice for older properties without actually running the 12.5% comparison — in some cases, particularly where the property appreciated unusually fast, the flat rate still wins even for an older holding.
• Ignoring the 23 July 2024 cut-off entirely and assuming every property seller automatically gets to choose — properties acquired on or after that date are taxed at 12.5% with no indexation option.
• Forgetting that this choice only applies to resident individuals and HUFs selling land or buildings, not to other categories of assets or taxpayers.
• Treating the rate-regime decision and the Section 54/54F reinvestment decision as unrelated, when in fact the reinvestment exemption is calculated on top of whichever gain figure the rate choice produces.
• Using outdated Cost Inflation Index figures from before the regime clarified rather than the correct table published for the relevant assessment year.

As you shortlist that next property, the property tax calculator helps you check the ongoing property-tax outgo before you commit. And when you're ready to search, the buyer hub is the starting point for discovering your next home with DrawMagic's broader intelligence tools.

A Note on Getting This Right

The rupee difference between the two routes can run into lakhs on a single sale, which is exactly why this is worth computing carefully rather than defaulting to whichever regime sounds simpler. DrawMagic's paid plans (see pricing) extend the financial-planning tools further if you want ongoing modeling through the transaction; for the actual tax filing and computation, this article is informational only — always confirm your final numbers with a licensed CA before you file, since a difference in the CII figures used, the improvement costs claimed, or the acquisition date can materially change which route wins.

Key Takeaways

• From 23 July 2024, LTCG on property defaults to 12.5% without indexation; properties acquired before that date get a grandfathered choice between 12.5% (no indexation) and 20% (with indexation), whichever computes to lower tax.
• The choice applies to resident individuals and HUFs on land and buildings acquired before the cut-off date — properties acquired after it are taxed at 12.5% with no indexation option.
• Older, low-cost-of-acquisition properties (such as a 2005-bought flat) tend to favor indexation; recently bought, high-appreciation properties often favor the flat 12.5% rate — but always compute both.
• Reinvestment exemptions under Section 54 and Section 54F still apply on top of whichever rate route you choose, and Section 54's exemption is capped at Rs 10 crore since AY 2024-25.
• Cities with faster recent price appreciation, such as Bengaluru (around 13.1% YoY per NHB RESIDEX Q4 FY25) and Kolkata (around 9.6% YoY), are where the rupee gap between the two routes tends to be largest.
• Always use the actual Cost Inflation Index for your specific acquisition and sale years — don't rely on rules of thumb.
• This is general information on tax mechanics, not personalized tax advice — verify your final computation with a licensed CA before filing.
• Model both routes' after-tax proceeds before finalizing your sale price or reinvestment budget.

FAQ

Do I automatically get to choose between 12.5% and 20% on every property sale? No. The choice is available only for land and buildings acquired before 23 July 2024, and only for resident individuals and HUFs. Properties acquired on or after that date are taxed at 12.5% with no indexation option.

Does choosing the 20%-with-indexation route affect my Section 54 exemption? No — the reinvestment exemption under Section 54 or 54F applies to the computed gain regardless of which rate route produced that gain. The rate choice and the reinvestment exemption are separate, sequential steps.

Where do I find the correct Cost Inflation Index figures? The Cost Inflation Index is published annually by the Income Tax Department; use the officially notified table for your specific acquisition year and sale year rather than an old or unofficial figure, since using the wrong year materially changes your indexed cost of acquisition.
