Claiming Cost of Improvement on NRI Property Sale

Twelve years ago, Ravi added a second bedroom and a covered balcony to his parents' flat in Pune. He paid the contractor in cash instalments, verbally agreed the scope over three visits home from Dubai, and never thought about a paper trail because the flat wasn't going anywhere. Now the flat is going somewhere — a buyer has made an offer — and Ravi's CA has just asked him a question he cannot fully answer: "Do you have anything showing what you spent on that room?"

This is the single most common way NRIs leave money on the table when they sell property in India. The tax law is generous here — genuine capital improvements reduce your taxable gain, sometimes by a meaningful margin — but the law rewards paperwork, not memory. If you're staring at an upcoming sale and wondering whether that renovation, that extra floor, or that structural strengthening work can lower your tax bill, this article walks through exactly what qualifies, what doesn't, and how to build the proof file a CA can actually use. As always, treat this as a framework for the conversation with your chartered accountant, not a substitute for one — DrawMagic is an information platform, not a tax advisor.

Where Cost of Improvement Sits in the Capital Gains Formula

When you sell a property, your taxable capital gain is not the sale price. It's the sale price minus a set of deductions the Income Tax Act allows you to net off first. According to ClearTax's guide on TDS on sale of property by NRIs, the broad computation for a long-term capital asset is:

Sale Consideration − Cost of Acquisition − Cost of Improvement − Transfer Expenses = Capital Gain

"Cost of improvement" is its own line item, separate from what you originally paid to buy or build the property. It captures money spent after acquisition that added to, or substantially altered, the capital value of the asset — as opposed to money spent keeping it in the same condition it was already in. That distinction between "adding value" and "maintaining value" is the entire ballgame, and it's the part most sellers get wrong when they're reconstructing years of spending from another country.

For NRIs specifically, this matters more than it might for a resident seller, because the buyer is required to deduct TDS under Section 195 on the transaction, and getting your computation right — with documented improvement costs backing it up — is often the difference between a fair TDS rate under a lower-deduction certificate and a much larger amount getting withheld on the gross sale price. Building this computation properly is exactly the kind of structured number-crunching DrawMagic's financial planning suite is built to help you organize before you hand it to your CA.

Step by Step: Identifying, Proving, and Computing the Deduction

Step 1 — Separate capital improvement from repair and maintenance. Before you list a single expense, sort your spending history into two buckets. Capital improvement is work that adds a new asset, a new room, a structural change, or a durable upgrade that increases the property's value or useful life. Repair and maintenance is work that restores the property to its existing condition — repainting a wall, fixing a leaking tap, replacing a broken tile with an identical one. Only the first bucket counts.

Step 2 — Gather documentary evidence for every item in the capital bucket. For each qualifying improvement, you want: a dated contractor invoice or bill describing the scope of work, proof of payment (bank transfer, cheque, or NRE/NRO account debit — cash payments above certain thresholds create their own complications and are harder to defend), and where relevant, a copy of the approved building plan or municipal permission if the work involved structural addition.

Step 3 — Total the qualifying spend by financial year. Because indexation (where applicable) is computed year-wise based on when the cost was incurred, you'll need each improvement dated to the financial year in which the money was actually spent, not the year the work was "decided."

Step 4 — Decide the indexation path. Under the post-2024 LTCG regime, ClearTax notes that NRI sellers on certain property transactions can choose between a 12.5% rate without indexation or a 20% rate with indexation, with the with-indexation route allowing the cost of acquisition and cost of improvement to be inflated for the number of years held using the Cost Inflation Index. Whether indexation benefits you depends on how long you've held the property and how the numbers work out — this is a computation your CA should run both ways before you file, since the "cheaper" headline rate isn't always cheaper once indexation is factored in.

Step 5 — Net the improvement cost against the sale consideration alongside acquisition cost and transfer expenses, arriving at your final long-term capital gain figure — the number TDS and, eventually, your tax liability, is based on.

Qualifies vs Does Not Qualify: A Working Reference Table

Because "improvement" is a judgment call in some cases, here's a table of common NRI-seller scenarios and how they typically get treated. Always confirm edge cases with your CA — this is a starting framework, not a ruling.

Why Documentation From Abroad Is the Real Battle

Every NRI who has been through this will tell you the tax rule itself is not the hard part — assembling the proof is. You were possibly living in Dubai, London, or Toronto while a local contractor, a family member, or a property manager oversaw the work in India. Payments may have gone through a mix of NRE remittances, NRO account debits, and sometimes cash handed over during a home visit. Years later, invoices are lost, the contractor has changed his phone number, and the flat has been repainted twice since, obscuring what was original and what was added.

The fix has to be forward-looking for anyone who hasn't sold yet: keep a single folder — physical or, better, a shared cloud drive — where every renovation invoice, payment receipt, and approved plan gets dropped the same week the work happens. If you're already at the point of selling and the paperwork is patchy, reconstruct what you can: bank statements showing lump-sum transfers around the renovation dates, WhatsApp or email exchanges with the contractor describing scope, and photographs with metadata dates can all support a CA's case, even if they're not as clean as original invoices. DrawMagic's help center has guidance on organizing this kind of document trail before you sit down with a professional.

The indexation choice compounds the documentation question: if you're claiming indexation on the improvement cost, you need the improvement dated to a specific financial year, which is another reason contemporaneous records beat reconstructed memory every time.

Mini Scenario: The Renovated Pune Flat

Consider an NRI based in Singapore who bought a 2BHK flat in Pune's Kothrud area in 2011. In 2016, she added a study room by enclosing a balcony and upgraded the kitchen with a modular fit-out, spending roughly ₹9 lakh across both, paid via bank transfer and backed by contractor invoices she'd kept because her husband is an accountant. In 2026, she sells the flat.

Her capital gains computation, in simplified form, nets the original cost of acquisition, the ₹9 lakh documented improvement (indexed for the applicable years if she opts for the indexation route), and transfer expenses like brokerage, from the sale price. That ₹9 lakh — indexed upward for roughly a decade of inflation under the Cost Inflation Index — could meaningfully reduce her taxable gain compared to a seller who made the same improvements but never kept the invoices and simply cannot claim them. The difference between the two sellers isn't the law; it's a folder of paper.

Section 54: Reducing Tax on What's Left

Even after subtracting cost of improvement and transfer expenses, there may still be a taxable long-term capital gain. This is where Section 54 of the Income Tax Act can help further: it allows exemption on capital gains from the sale of a residential house if the gain (or, depending on the specific provision, the net consideration) is reinvested in another residential property in India within the prescribed time windows, subject to a cap and conditions set out by the Income Tax Department. If you're planning to buy another home in India — or already have one lined up — this reinvestment relief and your improvement-cost deduction work together, not against each other: improvement cost lowers the gain first, and Section 54 can shelter some or all of what remains.

Pro Tips

1. Start your improvement file the day the work begins, not the year before you plan to sell. Retroactive reconstruction is always weaker evidence.
2. Route payments through your NRE/NRO account rather than cash wherever possible — a bank trail is the single strongest piece of evidence a CA can use.
3. Ask your contractor for a scope-of-work invoice, not just a payment receipt — "renovation work" as a description is far weaker than "addition of one bedroom, 180 sq ft, RCC structure."
4. Keep municipal approvals for any structural addition — beyond supporting your tax claim, they also protect you from title and compliance issues at resale.
5. Run the indexed and non-indexed computations both ways with your CA before choosing the LTCG regime — the better option depends on your specific holding period and improvement timeline.

Common Mistakes to Avoid

1. Claiming routine repairs as improvements. A repainting job or a fixed leaking tap will not survive scrutiny as a capital improvement.
2. Relying on verbal agreements with contractors with no invoice trail — memory is not evidence.
3. Losing track of which financial year an expense belongs to, which breaks the indexation calculation.
4. Assuming cash payments are equally valid as bank payments for large sums — they invite more questions, not fewer.
5. Waiting until the sale is imminent to start assembling documents instead of maintaining records as you go.

FAQ

Q: Can I claim cost of improvement if I've lost the original invoices? A: It's harder, but not automatically impossible — bank statements showing payments around the renovation period, contractor communication, and dated photographs can help support a claim, though original invoices are the strongest evidence. Discuss the specifics with your CA.

Q: Does painting the house before sale count as an improvement? A: Generally no. Routine painting and touch-ups to restore the property's existing condition are treated as maintenance, not capital improvement, and don't reduce your taxable gain.

Q: Does the cost of improvement get indexed the same way as the original purchase price? A: Where the indexation option applies, improvement costs are indexed based on the financial year in which they were actually incurred, not the year you bought the property — this is why dating each expense correctly matters.
