Capital Gains When Sale and Purchase Fall in Different Years

"I sold in March. I'm buying in August. Which year do I pay tax in?"

It's a question that trips up more sellers than you'd expect, precisely because it sounds like it should have a complicated answer. A homeowner sells their flat in late February, expecting to close on a replacement home by the following August or September. Somewhere between the sale and the purchase, 1 April arrives — the start of a new financial year — and suddenly they're not sure which year's tax return the sale belongs to, whether the financial-year change resets their reinvestment clock, or whether they need to do anything before 31 March to protect their exemption.

The short answer: the financial-year boundary matters for when you report the gain, but it does not reset or restart your reinvestment window under Section 54. That window is anchored to your sale date, full stop. This article walks through exactly how the two interact, using a concrete cross-year example, so the "which year?" question stops being a source of anxiety.

Financial year vs assessment year, and why the reinvestment window doesn't care about 1 April

India's financial year (FY) runs from 1 April to 31 March. The income you earn — including capital gains — in a given FY is assessed and reported in the corresponding assessment year (AY), the year immediately following. So a sale on 20 February 2026 falls in FY 2025-26, and the gain is reported in your return for AY 2026-27, due (for most individual taxpayers) by around 31 July 2026 — the trigger date under Section 139(1) that also governs when unutilised gains must be deposited into a Capital Gains Account Scheme (CGAS) account.

Crucially, Section 54 of the Income Tax Act measures its reinvestment window from the date of sale, not from the end of the financial year in which the sale falls. You get two years from the sale date to buy an existing house (or one year before the sale, if you bought early), or three years from the sale date to construct a new one. A sale in February 2026 gives you until roughly February 2028 to complete a qualifying purchase — the fact that a new financial year started in April 2026, and possibly another in April 2027, is irrelevant to that count. Tax2win's Section 54 guide (2026) confirms the same window and reinforces that the ₹10 crore exemption cap and the CGAS deposit mechanism both key off this sale-date-anchored timeline, not the FY calendar.

So the honest answer to "does the FY boundary reset my window" is no. What the FY boundary does affect is which year's return you must report the gain in, and by when you must either complete the reinvestment or deposit the gain into CGAS.

Step by step: mapping sale date to CGAS deadline to purchase date to ITR

1. Fix the sale date. This is your anchor for everything — the FY/AY it falls in, and the start of your 2-year (purchase) or 3-year (construction) reinvestment clock.
2. Identify the FY and AY of the sale. A sale between 1 April and 31 March of a given year belongs to that FY; you report it in the ITR for the following AY.
3. Identify your ITR filing due date for that AY. This is commonly 31 July of the AY for most individual, non-audit taxpayers, though the date can shift in specific years — confirm the current one each filing season.
4. Decide whether you'll close the purchase before that filing due date. If yes, you report the sale, the gain, and the completed reinvestment together, and no CGAS deposit is needed. If the purchase will close after your filing date — which is exactly the February-sale, August-purchase scenario — you must deposit the unutilised gain into CGAS before you file, to keep the exemption alive across the FY boundary.
5. Complete the purchase within the overall window (2 years from sale date for buying, 3 years for construction), regardless of how many financial years that spans.
6. Report the eventual utilisation. Once the purchase is registered, the CGAS withdrawal and the exemption claim are documented and reconciled — typically your CA will note this against the original claim made in the return for the year of sale.
7. Use a planning tool to hold all four dates together — sale date, filing due date, CGAS deposit date, and target purchase date — so nothing slips. DrawMagic's financial planning workspace is designed to let you line these up visually against your specific dates rather than tracking them across separate notes and reminders.

Timeline of a cross-FY deal

Mini scenario: February sale, following-August purchase

A Pune-based couple sells their apartment on 20 February 2026 for a long-term gain of ₹38 lakh. They haven't finalised a replacement home yet — they're evaluating two societies and want to complete due diligence properly rather than rush. Their ITR for AY 2026-27 (covering the February sale) is due by around 31 July 2026. Since they haven't closed on a new home by then, they deposit the full ₹38 lakh into a CGAS account before filing, and claim the Section 54 exemption in that return on the basis of the deposit. In August 2026, they finalise and register the purchase of a home priced above their gain amount, withdraw the CGAS funds against that purchase, and the exemption stands — fully within their two-year window from the original February 2026 sale date, and entirely unaffected by the fact that the sale and purchase legs fell in different financial years.

Reporting in the ITR: what Schedule CG shows

At a high level, capital gains from property sales are reported under Schedule CG (Capital Gains) of the income tax return for the year of sale. The schedule captures the sale consideration, the indexed cost of acquisition, the resulting long-term capital gain, and the exemption claimed under Section 54 — including, where applicable, the amount deposited into CGAS in lieu of a completed purchase. When the purchase later closes (potentially in a subsequent FY), that transaction doesn't require you to revise the original return; instead, it's the documentation trail — the CGAS deposit receipt and later the purchase deed — that substantiates the exemption you already claimed. If the eventual purchase amount ends up lower than the deposited gain, or the window closes without a qualifying purchase, the unutilised balance becomes taxable capital gains in the year the window lapses, and that's when a fresh entry is needed. Because the exact treatment can vary by individual circumstance, it's worth having a CA review your Schedule CG entries in the year of sale and again when the CGAS funds are eventually utilised.

An NRI note on cross-year timing

For NRI sellers, cross-year timing carries an additional wrinkle: TDS under Section 195 is typically deducted by the buyer at the time of sale, often at a rate higher than the seller's actual final tax liability once exemptions are applied. When the sale and purchase straddle two financial years, the NRI seller may need to claim a refund of excess TDS in the return for the year of sale, while separately tracking the CGAS deposit and eventual reinvestment. The interplay between TDS credit, the CGAS deposit, and the exemption claim is genuinely more complex for NRIs than for resident sellers — confirm the specific mechanics with a CA experienced in NRI taxation before filing.

Pro tips

• Write down your sale date, filing due date, and target purchase date together the moment the sale registers — don't let the FY change lull you into thinking the clock reset.
• If you're even slightly unsure you'll close before your filing due date, deposit into CGAS. There's no cost to depositing and using the funds quickly afterward; there's real cost to missing the deadline.
• Keep your CGAS deposit and sale deed on file together — your CA will reference both when preparing the ITR for the year of sale and again when reconciling the eventual purchase.
• If your purchase is a self-construction rather than a resale, remember you have three years, not two, from the sale date — useful if you're building rather than buying.
• Use DrawMagic's property tax calculator to sanity-check your estimated taxable gain and any residual liability if you expect only a partial reinvestment.

Common mistakes to avoid

• Assuming the FY boundary resets the reinvestment window. It doesn't — the window is anchored to the sale date, not to 1 April.
• Missing the CGAS deposit deadline because the purchase "felt" imminent, only for negotiations or loan approval to run past the ITR filing due date.
• Filing the ITR for the sale year without addressing the unreinvested gain at all — silence isn't a valid substitute for either completing the purchase or making the CGAS deposit.
• Not revisiting Schedule CG once the purchase actually closes, leaving the exemption claim undocumented on the substantiating paperwork side even though the tax position itself was correctly protected by the timely CGAS deposit.

How DrawMagic fits into this

Cross-year transactions are exactly where a simple visual timeline prevents costly mistakes.

Once you have a purchase price range in mind, the property tax calculator helps you sanity-check the ongoing cost side of the new home alongside the one-time capital gains exemption math. And if you want guidance on how to use DrawMagic's planning surfaces for your specific situation — not tax advice, but help navigating the tools — the help center is the right starting point.

Key takeaways

• The Section 54 reinvestment window (2 years to buy, 3 years to construct) runs from your sale date, not from the financial-year boundary — a cross-FY deal can be entirely within time.
• Your capital gain is reported in the ITR for the assessment year corresponding to the financial year of the sale, regardless of when the replacement purchase later closes.
• If the purchase won't close before your ITR filing due date (commonly around 31 July), deposit the unutilised gain into CGAS before filing to preserve the exemption.
• Schedule CG in your ITR captures the sale, the gain, and the exemption claimed — including CGAS deposits made in lieu of a completed purchase.
• NRI sellers face an added layer: Section 195 TDS credit and refund timing interact with the CGAS deposit and exemption claim across financial years.
• Keep the CGAS deposit receipt, sale deed, and eventual purchase deed together as your documentation trail.
• The financial-year change itself has no bearing on your reinvestment deadline — don't let it create false urgency or false comfort.
• This is general information, not tax advice — confirm your exact dates and Schedule CG treatment with a licensed chartered accountant.
