The Section 79 Trap: Why Buying 51%+ Equity Wipes Out Tax Losses

Quick answer: Section 79 of the Income Tax Act lapses a closely held Indian company's accumulated business losses the moment the persons holding at least 51% of its voting power in the loss year stop holding that same bloc in the year the loss would be set off. Buying majority equity typically breaks that continuity outright, and the loss isn't reduced proportionally, it's gone. Unabsorbed depreciation survives independently under Section 32(2). A handful of narrow exceptions exist — DPIIT-recognized start-ups, NCLT resolution plans, and certain amalgamations under Section 72A — but outside those, don't underwrite a target's tax losses as a reliable future shield without specialist confirmation before closing.

A target company walks into diligence with a healthy stack of accumulated business losses on its books, and it's tempting to read that as a future tax shield baked into the price. For most majority acquisitions of a closely held Indian company, that read is wrong, and the mechanism that makes it wrong is easy to miss because it does its damage silently, on the very transaction that triggers it.

The Core Rule

Section 79 targets companies in which the public are not substantially interested — in practice, this covers the overwhelming majority of privately held Indian SME targets. The test asks a single question: do the same persons who held at least 51% of the voting power in the year the loss was incurred still hold that same 51% bloc in the year the loss would be carried forward and set off?

If the answer is no, the loss lapses. Not partially, not proportionally to whatever percentage actually changed hands — the full accumulated business loss simply stops being available for set-off from that point forward. A straightforward majority acquisition, where a new buyer takes over 51% or more of the company's equity, is exactly the kind of event that breaks this continuity as a matter of course.

This is a mechanical, backward-looking test applied at the point the loss would be used, not a one-time penalty assessed at the moment of sale. A buyer who takes majority control doesn't need to do anything further to trigger it — the disqualification is built into how the set-off provision reads the ownership history.

What Actually Survives the Change in Control

Unabsorbed depreciation does not lapse. This is the distinction that trips up buyers who've heard "the losses die on acquisition" and assume it applies to the whole tax-loss position. It doesn't. Section 32(2) carries forward unabsorbed depreciation as its own, separate mechanism, and it has no shareholding continuity condition attached to it at all. A company can lose its entire accumulated business loss carry-forward on the day you take control and keep its unabsorbed depreciation carry-forward completely intact, because the two provisions simply don't talk to each other.

For diligence purposes, this means the two figures on a target's tax computation need to be evaluated separately, not netted together as one undifferentiated "carry-forward" number. One of them is fragile the moment control changes hands. The other typically isn't.

The Narrow Exceptions

Section 79 carves out a small number of situations where the continuity break doesn't cost the company its losses:

1. DPIIT-recognized eligible start-ups, which get a relaxed version of the continuity test rather than the strict 51%-bloc requirement applied to ordinary closely held companies.
2. Changes in shareholding under an NCLT-approved resolution plan, where the restructuring happens through the insolvency process rather than an ordinary share purchase.
3. Certain amalgamations and demergers, which are governed separately under Section 72A rather than Section 79, and can preserve losses under their own distinct conditions.

None of these apply to the typical case of a buyer negotiating a straight majority share purchase with a promoter. If your target genuinely falls into one of them, get it confirmed in writing by a tax specialist as part of diligence, not assumed from a general resemblance to the exception.

Where the Law Still Isn't Settled

Group-structured acquisitions raise a genuinely unresolved question: does continuity of beneficial ownership through an intra-group transfer satisfy Section 79, even where the direct legal shareholder technically changes? Indian High Courts have gone different ways on this. The Karnataka High Court has been willing to look through to beneficial ownership continuity in some intra-group fact patterns. The Delhi High Court has taken a stricter, more literal reading of who "held" the shares.

If your deal involves moving a target between entities within a buying group, or structuring the acquisition through an intermediate holding vehicle, don't treat a beneficial-continuity argument as settled law. It's a real argument, but it's a jurisdiction-dependent one, and it needs a tax opinion specific to your structure rather than a general assumption that "we still control it" is enough.

What This Means for How You Value the Target

Accumulated business losses on a target's balance sheet look like free future tax savings, and sellers sometimes price them that way in negotiations. Treat that framing skeptically in a standard majority acquisition. Unless the deal clearly fits one of the three narrow exceptions above, and a specialist has confirmed it in writing before signing, the safer underwriting assumption is that the accumulated business losses do not survive your purchase, and shouldn't be counted as a value driver in how you're valuing the business. This sits alongside the other inherited-liability surprises worth checking during due diligence on an Indian SME — it's the same discipline that also applies to the TDS history you inherit in a share purchase: the tax position you're buying is rarely exactly what it looks like on the target's own books.

Frequently Asked Questions

Does buying more than 50% of an Indian company's shares always wipe out its tax losses?

For a closely held company, yes, in the standard case. Section 79 lapses accumulated business losses the moment the persons who held at least 51% of voting power in the loss year no longer hold that same bloc when the loss would be set off. The loss isn't reduced or partially preserved, it lapses entirely, unless one of a small number of exceptions applies.

Does unabsorbed depreciation lapse the same way?

No. Section 32(2) carries forward unabsorbed depreciation independently of Section 79 and has no shareholding continuity requirement. A change of control that wipes out business losses can leave the depreciation carry-forward completely untouched.

Are there any acquisitions where the losses survive a change in control?

Three narrow scenarios: acquisitions of DPIIT-recognized eligible start-ups under a relaxed continuity test, changes in shareholding under an NCLT-approved resolution plan, and certain amalgamations or demergers governed separately under Section 72A. Outside these, don't assume the losses are safe.

What if the acquisition happens within the same corporate group?

This is genuinely unsettled. The Karnataka High Court has recognized loss preservation where beneficial ownership continuity can be shown even through an intra-group restructuring, while the Delhi High Court has applied a stricter, more literal reading of the continuity test. Don't rely on a group-transfer argument without specialist confirmation for your specific structure.

Should I factor a target's accumulated losses into my valuation as a future tax shield?

Not by default. In a straightforward majority acquisition of a closely held company, treat the accumulated business losses as unlikely to survive the deal unless one of the narrow exceptions demonstrably applies, confirmed by a tax specialist before you close, not after.
