Capital Gains Exemption Under Section 54B vs Section 54D: Land Compared 2027
Ramesh sold agricultural land his family had farmed for decades and wanted to know which capital gains exemption applied, only to discover that the section depends entirely on how the land was transferred and what it was actually used for, not simply the fact that land changed hands. Capital gains exemption under Section 54B vs Section 54D covers two genuinely different situations, agricultural land sold voluntarily versus industrial property taken by the government, and mixing them up means chasing the wrong exemption entirely.
Who Can Even Claim Each
Section 54B is restricted to individuals and HUFs, companies, firms, and LLPs cannot use it at all. Section 54D is available to any assessee, including companies, since industrial undertakings are commonly owned by corporate entities, and the section was designed with that in mind. This is often the fastest way to know which section could even apply to you, if the taxpayer is a company, Section 54B is never an option regardless of anything else.
What Actually Triggers Each Exemption
Section 54B applies to agricultural land that was used by the taxpayer, their parents, or the HUF for agricultural purposes for at least 2 years before the transfer, and the transfer itself can be a genuinely voluntary sale, there is no requirement that the government or any authority force the transaction. Section 54D applies only to compulsory acquisition, the land or building, forming part of an industrial undertaking and used for that business for at least 2 years before acquisition, must be taken by the government or an authorised authority under some legal power, not sold by choice. A voluntary sale of industrial land does not qualify for Section 54D at all, that scenario falls outside this section entirely.
The Reinvestment Requirement Compared
Section 54B requires purchasing new agricultural land, rural or urban, within 2 years of the transfer date. Section 54D requires purchasing or constructing new land or building for setting up or shifting the same industrial undertaking within 3 years of receiving compensation, and interestingly also allows the reinvestment to happen up to 1 year before the compulsory acquisition itself, a flexibility Section 54B does not offer. Both sections allow the unutilised gain to sit temporarily in the Capital Gains Account Scheme if the reinvestment is not complete by the time you file your return, with the deposited amount taxed as income if it remains unused once the respective deadline passes.
The Lock-In Period on the New Asset
Both sections carry a 3-year lock-in on whatever you acquire with the exemption. Sell the new agricultural land under Section 54B, or the new industrial land or building under Section 54D, within 3 years of acquiring it, and the exemption you claimed gets added back, reducing the cost of the new asset for the purpose of computing capital gains on that subsequent sale. This lock-in exists in both sections for the same reason, to prevent the exemption from being used as a temporary parking mechanism rather than a genuine reinvestment.
The Exemption You May Not Need At All: Section 10(37)
Here is a genuinely important point that gets missed. If your agricultural land is compulsorily acquired by the government, rather than sold voluntarily, you likely do not need Section 54B at all. Section 10(37) provides a full exemption on capital gains from the compulsory acquisition of urban agricultural land, with no reinvestment requirement whatsoever. Section 54B is the rollover-based option for a voluntary sale, Section 10(37) is the far more generous option specifically for compulsory acquisition of the same type of land. If your agricultural land is being taken by the government, check whether 10(37) applies before assuming you need to reinvest under 54B to avoid the tax.
Capital Gains Exemption Under Section 54B vs Section 54D at a Glance
| Factor | Section 54B | Section 54D |
|---|---|---|
| Eligible taxpayer | Individual or HUF only | Any assessee, including companies |
| Original asset | Agricultural land, used 2+ years | Industrial undertaking’s land or building, used 2+ years |
| Trigger | Any transfer, including voluntary sale | Compulsory acquisition only |
| New asset required | New agricultural land | New land or building for the same industrial undertaking |
| Reinvestment window | 2 years after transfer | 3 years after compensation, or up to 1 year before acquisition |
| Lock-in on new asset | 3 years | 3 years |
| Exemption amount | Lower of capital gain or new asset cost | Lower of capital gain or new asset cost |
Short-Term or Long-Term Gains: Both Sections Cover Either
Neither section restricts itself to long-term capital gains alone, which is worth knowing since several other exemption sections, Section 54 among them, apply only to long-term gains. Under Section 54B, whether the agricultural land was held as a short-term or long-term asset, the exemption mechanism works the same way. Under Section 54D, since industrial land and buildings used in a business are often depreciable assets, gains on their compulsory acquisition are frequently short-term by classification even after many years of ownership, and the exemption still applies regardless. This is a meaningful practical advantage over exemptions tied strictly to a long-term holding threshold.
What Happens If You Only Partially Reinvest
Neither section demands all-or-nothing reinvestment. Under both Section 54B and Section 54D, if the cost of the new asset is less than the capital gain, the exemption is simply limited to whatever was actually reinvested, and the remaining gain stays taxable in the normal way. There is no penalty beyond that, partial reinvestment still gets partial relief, proportionate to what you put into the replacement asset. This makes both sections genuinely flexible for taxpayers who cannot or do not want to reinvest the entire gain, rather than an exemption that only works if you commit the full amount.
Worked Example
Ramesh sells his agricultural land voluntarily for a capital gain of Rs. 8,00,000 and buys new agricultural land for Rs. 8,00,000 within the 2-year window. Since his new investment fully covers the gain, the entire Rs. 8,00,000 is exempt under Section 54B, taxable gain is nil. Separately, a manufacturing company has its factory land compulsorily acquired, resulting in a Rs. 13,00,000 gain, and it buys new industrial land for only Rs. 2,00,000 within 3 years. Since the new asset cost is lower than the gain, only Rs. 2,00,000 is exempt under Section 54D, leaving Rs. 11,00,000 taxable, working out to roughly Rs. 1,43,000 in tax at 12.5% plus cess. Same underlying idea, rollover into a similar asset, but the taxpayer type, the trigger, and the outcome are all genuinely different between the two scenarios.
Using the Capital Gains Account Scheme for Either Section
If you cannot complete the reinvestment before your return filing deadline, both sections let you park the unutilised gain in the Capital Gains Account Scheme instead of losing the exemption outright. You deposit the amount in a designated bank account under this scheme, claim the exemption as if the reinvestment were already made, and then withdraw from the account to actually purchase the new asset within the section’s own time limit, 2 years for Section 54B, 3 years for Section 54D. If the money sits unused once that window closes, the unutilised portion is brought back into your income as a capital gain in the year the deadline expires, taxed as short-term or long-term depending on how the original gain was classified. This mechanism is identical across both sections, it simply gives you breathing room to find and close on the right replacement asset without losing the exemption purely because of timing.
Conclusion
Capital gains exemption under Section 54B vs Section 54D ultimately comes down to what kind of asset you are dealing with and how it left your hands. Section 54B covers agricultural land sold by an individual or HUF, voluntarily or otherwise. Section 54D covers industrial land or buildings taken specifically through compulsory acquisition, and is open to any taxpayer type. If your own agricultural land is being compulsorily acquired rather than sold, check Section 10(37) first, since it may make either of these sections unnecessary.

Frequently Asked Questions
Can a firm or LLP ever claim Section 54B by routing the sale through an individual partner?
The exemption depends on who actually owns and transfers the land, not on informal arrangements designed to route around the eligibility restriction. If the land genuinely belongs to and is sold by the firm, the firm’s ineligibility under Section 54B stands regardless of how the transaction is structured.
Does Section 54D apply if the industrial land is acquired by a private party rather than the government?
No, the acquisition must genuinely be compulsory, exercised under a legal power by the government or an authorised authority. A sale to a private buyer, however urgent or pressured, does not meet the compulsory acquisition requirement this section depends on.
Can I claim Section 54B if I buy new agricultural land jointly with a family member?
The exemption applies to the extent the reinvestment is genuinely yours, so a joint purchase generally allows you to claim the exemption proportionate to your own share of the new land’s cost, rather than the full amount if the investment is shared.
Is the new asset under Section 54D required to be in the same city as the original industrial undertaking?
No, the section allows the new land or building to be used for shifting the industrial undertaking to a new location or re-establishing it, so relocation to a different city is explicitly contemplated by the provision, not a barrier to claiming the exemption.
Does Section 54B apply if the agricultural land is located outside India?
Section 54B is generally understood to apply to agricultural land situated in India, both for the land sold and the new land purchased. NRIs can claim this exemption, but only where both the original and replacement land are located within the country.
What counts as an industrial undertaking for Section 54D purposes?
Broadly, a business engaged in manufacturing, processing, or producing goods, operating from the land or building in question. The undertaking must genuinely belong to and be run by the taxpayer claiming the exemption, rather than merely being land held with an intention to eventually set up such a business.
