How does the Section 54 exemption on capital gains from sale of a house work

Question

I sold my residential house and plan to buy another one, and I want to know how much capital gains tax I can save. I would like to understand which provision governs this, what it entitles me to, and how long I have before the remedy lapses. I also want to know whether I need a lawyer for this or can do it myself.

In India, the answer to "How does the Section 54 exemption on capital gains from sale of a house work" turns on Income-tax Act, 1961, Section 54, Income-tax Act, 1961, Section 45 and Income-tax Act, 2025. The points below set out the position and then what to do about it, in the order it should be done.

Section 54 exempts long-term capital gains arising from transfer of a residential house if the gain is invested in purchasing one residential house in India within one year before or two years after the sale, or in constructing a house within three years, subject to the property being held for more than twenty-four months to qualify as long-term.

From Assessment Year 2021-22, a taxpayer can invest in two residential houses instead of one if the capital gain does not exceed Rs. 2 crore, but this option can be exercised only once in a taxpayer's lifetime.

If the exemption amount is not immediately utilised for purchase or construction, it must be deposited in the Capital Gains Account Scheme before the due date of filing the return under Section 139(1), and failure to utilise the deposited amount within the prescribed period makes the unutilised balance taxable as capital gains of the year in which the period expires.

Selling the new house within three years of its purchase or construction triggers withdrawal of the exemption, and the cost of the new asset is reduced by the exemption amount for computing capital gains on the subsequent sale.

In practice, in this order: 1) Compute long-term capital gains after indexation on the original sale; 2) Identify a replacement house within the statutory time limits; 3) Deposit unutilised gains in a Capital Gains Account Scheme before the return due date; 4) Retain purchase or construction documents to substantiate the exemption claim.

Timing matters here: Income-tax Act, 1961, Section 54 works on limitation periods, so a section 54 exemption claim that is right on the merits can still fail if it is brought late.
