Sold an asset? See your Section 54 / 54F reinvestment windows — as actual calendar dates.
Quick answer · 25 July 2026 — Enter what you sold, for how much, and in which month. This tool shows four things, all of them indicative: the simple gain arithmetic (sale proceeds minus cost — the real figure is your CA's computation, not this subtraction), whether Section 54 or Section 54F is the one that likely applies, your purchase and construction reinvestment windows as calendar dates counted from your sale month, and the Capital Gains Account Scheme deadline that sits before them. It is educational only: it promises no tax outcome, and every number it shows needs your Chartered Accountant's confirmation before you act on it.
New to the topic? Start with the plain-language answer page — Sold your property — now what? — for the three clocks, the Section 54 vs 54F table, and the honest FAQ. Then come back and compute your own dates.

What this tool does — and deliberately doesn't
It does simple statute mechanics: the two sections' reinvestment windows, counted from your sale month, and the deposit deadline that protects an unfinished reinvestment. It deliberately does not compute your actual tax: no indexation, no grandfathering, no rates, no exemption amount. Those depend on facts only your Chartered Accountant can verify — this page is a map, not the journey. Everything you type stays in your browser; this page does not transmit or store your figures.
Your sale, in four fields
Indicative — confirm with your CA.
Your indicative results
Every block below is labeled INDICATIVE because it is: month-level dates from a month-level input, and a gain figure that is subtraction, not a computation. Your CA anchors the real dates to your exact date of transfer and computes the real figures.
Estimated long-term gain
This is sale proceeds minus approximate cost, nothing more. Indexation (cost-inflation adjustment) and grandfathering rules vary by asset and year — the figure your return actually uses is your CA's computation, not this subtraction. This tool also assumes the asset qualifies as long-term; holding-period rules differ by asset type.

The windows, counted from your sale month
Purchase means an existing or ready residential house: the window runs from one year before your sale to two years after it. Construction means building, or a property whose completion is what counts: up to three years from the sale. Both clocks anchor to your exact date of transfer — with only a month entered here, treat these as month-level markers.
Indicative — confirm with your CA.
The earliest clock: your CGAS deposit
If part of the amount is still uninvested when your income-tax return falls due, depositing the unutilised amount in a Capital Gains Account Scheme (CGAS) account before the filing deadline is what preserves the claim. The date above is the typical due date for individuals not requiring audit — extensions happen and audit cases differ, so your CA confirms your exact deadline.
Indicative — confirm with your CA.
Conditions the calendar dates don't show
- Section 54F ownership condition: on the date of sale you should not own more than one residential house other than the new one you are buying — owning more can take 54F off the table.
- Hold the new property: selling the new residential house within about three years can undo the exemption you claimed.
- CGAS before the return: amounts not yet reinvested by your return-filing deadline need the CGAS deposit (previous block) to keep the claim alive.
Indicative — confirm with your CA.
