Property capital gains: what actually changed when indexation went

The July 2024 Budget rewrote how property gains are taxed, and the version most people describe is not quite the version that exists. Indexation was not simply abolished; it survives as a cap on tax payable for one specific group of sellers, and the distinction between "a lower tax" and "a lower gain" turns out to decide several other things you might want to do with the money.

The two regimes, and who gets a choice

Property acquired on or after 23 July 2024 is taxed on a long-term gain at a flat 12.5%, with no indexation. There is no alternative to weigh.

Property acquired before 23 July 2024 and sold after it may be taxed at 12.5% without indexation or 20% with indexation, whichever produces the lower tax — but only where the seller is a resident individual or HUF. Non-residents, companies, firms and LLPs get the flat 12.5% with no choice.

Which route wins depends almost entirely on how much the property actually appreciated. A property that barely outpaced inflation has a large indexed cost and the 20%-with-indexation route usually wins; a property that multiplied in value has a gain so large that the lower 12.5% rate wins despite the bigger base. The property capital gains calculator computes both and names the cheaper one, which is the only reliable way to settle it.

The subtlety that changes what you can do next

This is the part that is almost universally reported wrongly, and it matters:

The indexation relief is a cap on the tax payable — it does not re-compute your capital gain.

The gain figure that everything else uses stays the without-indexation number. That figure is what counts for reinvestment relief, for setting off losses, and for carry-forward. Three consequences follow:

• Reinvestment relief is sized off the larger, un-indexed gain. If you are planning to roll the proceeds into another house or into specified bonds, the amount you must reinvest is calculated from that number, not the indexed one.
• The indexation route cannot create a loss. If indexing the cost produces a negative figure, that loss is not available to you — it is not a real loss, it is an artefact of a relief that only ever caps tax.
• It cannot enlarge a loss either, for the same reason.

So the honest summary: choose the cheaper tax, but do the rest of your planning off the un-indexed gain.

Reinvestment, and the rest of the arithmetic

Two long-standing routes reduce or defer the tax where the money goes back into qualifying assets — broadly, buying or building another residential house within the prescribed windows, or investing in specified capital-gains bonds within six months, each with its own ceiling and lock-in. Both are worth checking before you accept a tax bill as final, and both have conditions strict enough that they are worth taking to a professional rather than reasoning through from an article.

Two more things people forget in the gain itself: the cost of improvement is added to your base (and, on the indexed route, indexed from the year the improvement was actually made, not the year of purchase), and transfer costs — brokerage, stamp duty on sale — reduce the gain.

Finally, the whole exercise is a reminder of what a property position actually is. A flat is a large, undiversified, illiquid, usually leveraged holding, and the arithmetic of owning versus renting it in the first place is in rent vs buy. The listed alternative for the same underlying assets is in REITs and InvITs, and the treatment of gains on funds — a different regime again — is in mutual fund taxation.

⚠️ Rates, the 23 July 2024 cutoff, holding-period definitions, reinvestment ceilings and bond limits are all statutory and change. A property sale is a large, irreversible transaction — verify current rules and take professional advice. WealthTicker is not a SEBI-registered investment adviser and this is not tax advice.

Key takeaway

Property bought on or after 23 July 2024 is taxed at a flat 12.5% with no indexation. Bought before and sold after, a resident individual or HUF pays the lower of 12.5% without indexation and 20% with it. Critically, that relief caps the tax, not the gain — reinvestment relief, loss set-off and carry-forward all run off the un-indexed figure, and the indexed route can never manufacture a loss. Compute both routes before you sell, not after.
