Capital Gains Exemptions Explained: Sections 54 to 54GB After the Finance Act, 2026

A complete, plain-language walkthrough of Sections 54 to 54GB, and what's changed this year

Selling a property, land, or a long-held investment often comes with an unwelcome surprise: a large capital gains tax bill. What many taxpayers don't realise is that the law offers a genuine, legal way to reduce or completely wipe out that liability  provided you reinvest the gains correctly, within the right timeline, into the right kind of asset.

These reinvestment-linked exemptions live under Sections 54 to 54GB of the Income-tax Act, and each one is designed for a specific situation  selling a house, agricultural land, an industrial unit, or shares in a startup. Let's go through each one, and flag exactly what's changed under the Finance Act, 2026.

The Exemptions at a Glance

Section 54: Selling One House to Buy Another

If you sell a residential house held long-term and reinvest the gains into another residential house, you can claim a full exemption  up to the capped limit. You get one year before or three years after the sale to purchase, or three years to construct, a new house. There's also a one-time-in-a-lifetime option to invest in two residential houses instead of one, if your capital gains don't exceed ₹2 crore.

Section 54F: The Broader Version

This covers gains from selling any long-term capital asset other than a house  shares, gold, a plot of land, whatever it may be  as long as the entire net sale consideration (not just the gain) is reinvested into one residential house. A key condition: you shouldn't already own more than one residential house on the date of transfer, apart from the new one you're buying.

Section 54EC: The Bond Route

Instead of buying property, you can invest LTCG from the sale of land or building into specified bonds  currently REC, PFC, IRFC, and now HUDCO and IREDA  within six months of the sale. These bonds carry a five-year lock-in and a separate exemption cap of ₹50 lakh, distinct from the ₹10 crore limit that applies to Sections 54 and 54F.

Section 54B, 54D, 54G & 54GA: Business and Agricultural Reinvestment

• Section 54B applies when agricultural land is sold and the gains are reinvested in new agricultural land within two years.
• Section 54D covers land or buildings forming part of an industrial undertaking that are compulsorily acquired by the government, with reinvestment in new land or buildings for re-establishing the undertaking.
• Section 54G applies when an industrial undertaking shifts from an urban to a non-urban area, exempting gains reinvested in assets at the new location.
• Section 54GA works the same way, but specifically for relocation into a Special Economic Zone.

All four carry a similar structural condition: if the new asset is sold within three years of acquisition, the previously claimed exemption gets reversed and taxed.

Section 54GB: Supporting Start-Ups

This one's a little different  it allows individuals or HUFs selling a residential property to claim exemption by investing the proceeds in equity shares of an eligible start-up, which then uses the funds to buy specified plant and machinery. It's a deliberate policy tool to channel property-sale wealth into India's start-up ecosystem, subject to the company meeting eligibility conditions.

The ₹10 Crore Cap: Still in Force

Since Finance Act 2023 (applicable from AY 2024-25 onward), the maximum exemption available under Sections 54 and 54F has been capped at ₹10 crore  regardless of how much larger your actual capital gains might be. This cap continues to apply for FY 2025-26/AY 2026-27. Note that this ceiling doesn't extend to Section 54EC, which has its own, much lower ₹50 lakh limit.

What If You Can't Reinvest Immediately?

This is where the Capital Gains Account Scheme (CGAS) becomes useful. If you're unable to complete your purchase or construction before your ITR filing due date, you can deposit the unutilised gain in a CGAS account with an authorised bank, and still claim the exemption  as long as the amount is eventually used for the specified purpose within the applicable window (typically 2-3 years). If the deposit remains unused after that period, the unutilised amount becomes taxable as capital gains in the year the period expires.

When Exemptions Get Withdrawn

Every one of these sections comes with a clawback condition. Broadly:

• If the new asset (house, land, bonds) is sold or transferred within the prescribed lock-in  typically 3 years for property, 5 years for 54EC bonds  the previously claimed exemption is added back as capital gains in the year of the subsequent sale.
• If CGAS funds remain unutilised past the specified period, the unused portion is taxed as income in that year.

This is exactly the kind of detail that triggers scrutiny notices when it's missed  assessing officers routinely cross-check purchase and construction dates against transfer dates, and verify that ownership conditions (particularly under Section 54F) were genuinely met.

Looking Ahead: Renumbering Under the Income Tax Act, 2025

These provisions are being restructured under new section numbers as the Income Tax Act, 2025 takes over from the 1961 Act  for instance, what is Section 54F today is set to become Section 86 going forward. The substantive rules and conditions largely stay the same; it's mainly the numbering that changes. For your FY 2025-26 return (AY 2026-27), you'll still be working with the familiar Section 54-series numbers.

The Bottom Line

Capital gains exemptions aren't automatic  they require proactive planning before you even complete the sale. Knowing which section fits your asset, respecting the reinvestment timeline, keeping the ownership conditions in mind, and using CGAS when you need breathing room can be the difference between a hefty tax outflow and a completely legal exemption.
