Section 54 (Capital Gains Exemption on House)

Section 54 was one of the most widely used capital gains tax provisions in India for individual and HUF (Hindu Undivided Family) taxpayers. When a residential property held for more than 24 months (the long-term holding threshold for immovable property as of the Finance Act 2017) was sold, the resultant long-term capital gain was typically taxable at 20 percent with indexation benefit (prior to Budget 2024) or 12.5 percent without indexation (post Budget 2024 changes). Section 54 allowed this tax liability to be entirely or partially eliminated if the sale proceeds or gains were reinvested in a new house.

The key conditions for claiming the exemption under Section 54 as of 2024 were: (1) The taxpayer (individual or HUF) must have sold a residential house. (2) The asset sold must have been a long-term capital asset (held for more than 24 months). (3) The taxpayer must purchase another residential house within one year before or two years after the date of sale, OR construct a new residential house within three years of the sale. (4) The exemption amount was the lower of the capital gain amount or the cost of the new residential house. (5) From Finance Act 2023, the exemption under Section 54 was capped at Rs 10 crore — a limitation on the use of Section 54 for very large real estate transactions.

A critical compliance requirement was the Capital Gains Account Scheme (CGAS). If the seller could not reinvest the capital gains before the due date of filing their income tax return, they were required to deposit the uninvested amount in a Capital Gains Account with a designated bank (under the Capital Gains Account Scheme, 1988). Funds deposited in CGAS were ring-fenced for the purpose of purchasing or constructing the new house and could not be used for other purposes. Failure to utilise the CGAS deposit within the stipulated period resulted in the capital gain becoming taxable in the year of lapse.

If the new house purchased under Section 54 was sold within three years of its acquisition, the exemption originally claimed was reversed: the capital gain on the earlier transaction, which was exempted, was added back and taxed in the year of the new sale, significantly increasing the tax liability on the second transaction.

Section 54F (for capital gains from assets other than residential property) and Section 54EC (for investment in capital gains bonds issued by NHAI, REC, and other specified entities, up to Rs 50 lakh) were related provisions that served a similar tax deferral or exemption purpose, making the overall Section 54 framework part of a broader set of capital gains reinvestment incentives in Indian income tax law.
