Indexation Removed: What It Means for NRI Sellers

Where did my indexation go?

If you bought a flat in India fifteen or twenty years ago and are only now getting around to selling it — a common story for NRIs who bought a home during a visit, planned to retire into it, and then settled permanently abroad instead — you likely remember indexation as the thing that made the tax bill manageable. Indexation let you inflate your original purchase price using the government's Cost Inflation Index before calculating your taxable gain, which for an old, low-cost acquisition could shrink the taxable gain dramatically.

Then you talk to a CA in 2026 and hear that the headline long-term capital gains rate is now 12.5% — and it comes without indexation. Naturally, the question is: am I worse off?

The honest answer is: it depends, and it's genuinely worth computing rather than assuming either way. According to ClearTax's 2026 guide on TDS on sale of property by NRIs, NRI property sellers actually have two paths available — 12.5% without indexation, or 20% with indexation — and which one wins depends on your specific numbers. This article walks through both, when each one is likely to be better, and how the choice interacts with the TDS your buyer withholds upfront.

What indexation did, and what changed

Indexation is a mechanism that adjusts your original acquisition cost for inflation before computing a capital gain, using the Cost Inflation Index (CII) published for each financial year. If you bought a flat for ₹20 lakh in 2006 and the CII has roughly tripled by the year you sell, your "indexed cost" for tax purposes might be treated as closer to ₹60 lakh rather than the original ₹20 lakh — shrinking your taxable gain substantially, even though your actual cash outlay back in 2006 was ₹20 lakh.

Before the post-2024 changes, indexation was paired by default with a 20% long-term capital gains rate — you got both the inflation adjustment and the 20% rate together as a package. What changed is that this package is no longer the only option, and it's no longer automatic. Now, per the ClearTax 2026 guide, sellers choose between:

• 12.5% without indexation — a lower headline rate, but applied to the raw (un-inflated) gain
• 20% with indexation — the older approach, still available, applied to the smaller (inflation-adjusted) gain

The effective rate under the no-indexation path works out to roughly 14.95% once surcharge and cess are layered on, per the same source. But "effective rate" is a red herring if you compare it directly to "20%" without also accounting for the fact that the base each rate is applied to is different. A lower rate on a bigger base can easily produce more tax than a higher rate on a smaller base — which is exactly why this needs a computation, not a glance at the headline numbers.

When 20%-indexed still beats 12.5%-no-index

As a general pattern (not a substitute for your own computation), the indexed path tends to win when:

• The holding period is long — the longer you've held the property, the more cumulative inflation adjustment indexation captures.
• The acquisition happened in an earlier, lower cost-inflation-index year, so the ratio between your original CII year and the sale year's CII is large.
• The property was bought in a genuinely low-price era relative to today's prices — an older flat bought for a modest sum in a city that has since seen substantial price appreciation is a strong candidate.

Conversely, the no-indexation 12.5% path tends to win when:

• The holding period is shorter within the long-term band (just past the long-term threshold, not decades)
• Price appreciation on the property has outpaced general inflation by a wide margin, meaning the indexed cost doesn't rise proportionally to the sale price
• The acquisition was relatively recent, so there's limited cumulative inflation adjustment to claim in the first place

Step-by-step: compute both options for your sale

1. Establish your original acquisition cost and year. For inherited property, this typically carries over from the original owner's acquisition — a detail worth confirming with a CA, since cost basis and holding period rules for inherited assets have specific treatment.
2. Look up the Cost Inflation Index for your acquisition year and your sale year.
3. Compute the indexed acquisition cost: original cost × (CII of sale year ÷ CII of acquisition year).
4. Compute Path A (no indexation): sale price minus original (un-indexed) acquisition cost minus allowable expenses, taxed at 12.5%.
5. Compute Path B (with indexation): sale price minus indexed acquisition cost minus allowable expenses, taxed at 20%.
6. Compare the two final tax figures and choose the lower one — your CA formalises this in your return.
7. Layer in surcharge and cess on whichever path applies, to get your actual effective liability.

Comparison table: 12.5% no-index vs 20% indexed across holding periods

Scenario: a flat bought in 2006, sold in 2026

Suresh, an NRI who moved abroad in 2010, bought a flat in Chennai in 2006 for ₹18 lakh. In 2026, he agrees to sell it for ₹1.4 crore. His CA runs both computations:

• Path A (12.5%, no indexation): taxable gain is approximately the full difference between ₹1.4 crore and ₹18 lakh (minus allowable transfer expenses), taxed at 12.5%.
• Path B (20%, with indexation): the ₹18 lakh original cost is inflated using the CII ratio between 2006 and 2026, producing a substantially higher "indexed cost" that shrinks the taxable gain before the 20% rate is applied.

Given the two-decade holding period and the scale of the cost-inflation-index movement over that span, Suresh's CA finds that Path B — 20% with indexation — produces the lower final tax bill in his case, despite the higher headline rate. This is exactly the "old acquisition, long hold" pattern where indexation's inflation adjustment does enough heavy lifting to beat the lower flat rate.

Contrast this with a hypothetical NRI who bought a flat in 2018 and sells in 2026 at a price that has appreciated sharply due to a specific locality boom rather than general inflation — for that shorter, faster-appreciating case, the 12.5% no-indexation path is more likely to come out ahead, because indexation over just eight years captures far less inflation adjustment relative to the actual price gain.

How the option interacts with TDS and refunds

It's important to understand that the buyer's Section 195 withholding happens upfront, regardless of which final option you choose. The buyer deducts TDS at the time of payment — either on the full consideration, or at a reduced rate if you've obtained a Section 197 lower-deduction certificate in advance. The choice between the 12.5% and 20%-indexed paths is finalised when you file your income-tax return, not at the moment of deduction.

This has two practical consequences:

1. If the TDS deducted upfront is higher than your final computed liability (common when no Section 197 certificate was obtained and the buyer withheld on the full sale value), you'll be owed a refund after filing — which can take time to process.
2. Applying for a Section 197 certificate in advance, once you already know roughly which of the two paths (indexed or non-indexed) you'll elect, lets you align the upfront withholding much closer to your actual final liability — improving your cash flow at closing instead of waiting for a refund cycle.

This is exactly why the sequence matters: figure out which of the two LTCG paths is likely to apply to your sale before the transaction closes, not after, so you can apply for the right lower-TDS order in time.

Pro tips

1. Always compute both paths explicitly — never assume the lower headline rate (12.5%) is automatically the cheaper outcome.
2. For inherited property, confirm the inherited cost basis and holding period with a CA before assuming either path's numbers — inheritance carries its own rules for cost and acquisition date.
3. Apply for a Section 197 certificate once you know which path you'll likely elect, so your upfront TDS aligns closely with your final liability instead of over-withholding.
4. Keep every historical acquisition document — the original purchase deed, any improvement costs, and (for inherited property) the prior owner's acquisition records — since indexation calculations depend entirely on this paper trail.
5. Use DrawMagic's financial planning workspace to model both after-tax outcomes side by side before you commit to a sale price or a TDS certificate application.

Common mistakes to avoid

• Assuming 12.5% is always better because it's the lower number. The base each rate applies to is different, so the comparison has to be done on the actual computed gain, not the headline percentage.
• Not knowing the inherited cost basis for an inherited property, leading to a wrong computation on either path.
• Waiting until after the sale to figure out which path applies, missing the window to apply for a Section 197 certificate that would have aligned the withholding better.
• Assuming the choice is made by the buyer at TDS time. It isn't — the buyer withholds under Section 195 regardless; the path election happens on your own return.
• Forgetting to account for surcharge and cess when comparing the two paths' effective rates.

How DrawMagic fits into this

DrawMagic is a software and information platform, not a tax advisor — the actual election between the two LTCG paths needs a licensed CA who can run the precise numbers against your acquisition records. Where DrawMagic helps is in organising the decision: use DrawMagic's financial planning suite to model both after-tax outcomes side by side before you finalise a sale price, DrawMagic's property tax calculator for an indicative comparison of the two paths, and DrawMagic's buyer workspace to keep your original acquisition documents and cost records organised — the same records your CA will need to run the indexation computation. For questions about navigating the process itself, DrawMagic's help centre is available.

Plan the better option in advance, not after the fact

The NRI sellers who come out ahead under the current regime aren't the ones who guess between 12.5% and 20% — they're the ones who run both computations early, while there's still time to apply for the right Section 197 certificate and align their cash flow with the outcome they've actually chosen.

Key takeaways

• Indexation hasn't disappeared — it's now an optional path (paired with a 20% rate) rather than the automatic default it used to be.
• The alternative, 12.5% without indexation, applies to the un-inflated gain — a lower rate on a larger base, which isn't automatically cheaper.
• Long holding periods and older, low-cost acquisitions tend to favour the 20%-indexed path; shorter holds with sharp price appreciation tend to favour 12.5%-no-indexation.
• Inherited property carries over the original owner's cost basis and acquisition timeline — confirm this with a CA before computing either path.
• The buyer's Section 195 TDS withholding happens upfront regardless of which final path you choose; the election is made on your own tax return.
• A Section 197 lower-deduction certificate, applied for once you know your likely path, aligns upfront withholding with your actual final liability and avoids a long refund wait.
• Always compute both paths explicitly for your specific property — never assume based on the headline rate alone.
• Keep complete acquisition documentation; indexation calculations depend entirely on a clear cost-basis and date trail.

FAQ

Can I switch between the two options after filing my return? Generally, the election is made as part of the return for the year the gain arises; consult your CA about any revision window if you discover an error before the filing deadline passes.

Does the choice affect anything other than the tax rate — like eligibility for Section 54 reinvestment exemption? Section 54 reinvestment exemption is a separate mechanism from the indexation choice — reinvesting your gain into another residential property within the prescribed window can reduce or eliminate the taxable gain regardless of which of the two computation paths you use.

Is the 20%-indexed option only relevant for very old properties? Not exclusively, but the benefit scales with the holding period and how much the Cost Inflation Index moved over that span — always compute rather than assume based on age alone.
