Carrying Forward Losses in Amalgamations Under Section 72A

Every serious merger or acquisition in India runs a Section 72A test early in the diligence. The reason is money. A target company that has burned cash for years usually carries a substantial pool of accumulated business losses and unabsorbed depreciation. Under the general rule, those losses die with the company when it merges. Section 72A is the exception that keeps them alive by transferring them to the amalgamated company, where they can shield future profits from tax. For a loss-heavy target, this loss pool is often worth more than any operating asset on the balance sheet, and it drives whether a deal is done as an amalgamation, a slump sale, or an asset purchase.

This guide explains exactly how Section 72A works, the conditions on both companies, the Rule 9C compliance that most acquirers underestimate, and what happens if a condition is breached after the deal closes.

What Section 72A Does

The default position under the Income Tax Act is unforgiving. When Company A merges into Company B, Company A ceases to exist. Its right to carry forward and set off its own business losses under set-off and carry forward of losses is personal to Company A, and there is no general provision that lets Company B step into those losses. Without Section 72A, the accumulated loss pool of the amalgamating company would simply lapse on the appointed date.

Section 72A 1) rewrites that outcome for qualifying amalgamations. It provides that the accumulated loss and the unabsorbed depreciation of the amalgamating company shall be deemed to be the loss or, as the case may be, the allowance for unabsorbed depreciation of the amalgamated company for the previous year in which the amalgamation was effected. Once this deeming happens, the ordinary rules for set-off and carry forward apply as though the amalgamated company had incurred these losses itself.

Two consequences flow from the word "deemed for the previous year in which the amalgamation was effected":

• The inherited business loss starts a fresh eight-year carry-forward period under Section 72, counted from the year of amalgamation, not from the years the amalgamating company originally incurred the losses. A loss that was already six years old in the amalgamating company's hands effectively resets. This is a significant, and entirely legitimate, structuring advantage.
• The inherited unabsorbed depreciation carries no time limit at all. Under Section 32 2), unabsorbed depreciation can be carried forward and set off indefinitely, so the eight-year reset is relevant only to the business loss component.

Accumulated loss here means the business loss (not speculation loss) that the amalgamating company would have been entitled to carry forward under Section 72 had the amalgamation not taken place. Unabsorbed depreciation means the depreciation allowance that remains unabsorbed and would have been allowed to the amalgamating company. Capital losses and speculation losses are outside Section 72A and do not transfer.

Which Amalgamations Qualify Under Section 72A 1)

Section 72A does not apply to every merger. The amalgamating company must fall into one of the specified categories:

• A company owning an industrial undertaking or a ship or a hotel, amalgamating with another company;
• A banking company amalgamating with a specified bank (under Section 45 of the Banking Regulation Act framework);
• One or more public sector companies engaged in the operation of aircraft, amalgamating with one or more public sector companies in a similar business.

The most common category by far is the "industrial undertaking" limb. An industrial undertaking is broadly a business of manufacturing or processing goods, generation or distribution of electricity or any other form of power, mining, construction of ships, or the provision of telecommunication services. Pure trading companies, investment holding companies, and many service businesses do not own an industrial undertaking, which means their accumulated losses will not pass under Section 72A even in a genuine merger. This is a frequent and expensive surprise in diligence.

Beyond amalgamations, Section 72A also covers:

• Demergers under Section 72A 4), discussed in its own section below;
• Specified business reorganisations under Section 72A 5) and 6), including the amalgamation of certain co-operative banks and the succession of a firm or proprietary concern by a company under Section 47(xiii) and (xiv), subject to their own conditions.

Conditions on the Amalgamating Company: Section 72A 2)(a)

The transferor (the loss-making company) must satisfy two conditions measured up to the date of amalgamation. These test whether the business was real and substantial rather than a shell assembled to sell losses.

The three-year business test prevents a company from acquiring a dormant loss company and merging it purely for the tax attribute. The 75% fixed-asset continuity test prevents the transferor from stripping out its assets in the run-up to the merger while keeping only the losses. Both are asset-and-substance tests: the loss must be attached to a living business.

Conditions on the Amalgamated Company: Section 72A 2)(b) and Rule 9C

The transferee (the company that inherits the losses) carries the heavier compliance burden, and it runs for five years after the deal. Section 72A 2)(b) sets the statutory conditions, and Rule 9C prescribes the operational thresholds.

A few practitioner points that decide whether the benefit survives an assessment:

• The 50% capacity condition is the one acquirers forget. If the acquired plant runs below half its installed capacity for the relevant years, the set-off is at risk unless the Board grants a relaxation on genuine grounds (Rule 9C provides for the Central Government to relax the condition where it is satisfied the failure was for reasons beyond the company's control).
• Form 62 is not optional paperwork. It must be filed along with the return of income, backed by an accountant's certificate drawn from the books and production records. Missing or late Form 62 is a straightforward hook for the Assessing Officer to deny the carry-forward.
• The five-year holding and continuity conditions are forward-looking obligations. They are tested year by year, so a disposal of acquired plant in year four can unwind a benefit already claimed in years one to three.

Consequence of Breaching a Condition: Section 72A 3)

Section 72A is a conditional benefit granted upfront and clawed back on default. Under Section 72A 3), if any condition in Section 72A 2) is not complied with, the set-off of loss or allowance of depreciation already made in the hands of the amalgamated company is deemed to be the income of the amalgamated company chargeable to tax in the previous year in which the condition is breached.

In plain terms, the company may have set off Rs 6 crore of inherited loss in years one and two, reducing its tax. If it then fails the capacity test or sells the acquired assets in year three, that Rs 6 crore is added back as deemed income of year three and taxed then, along with the usual interest exposure. The benefit is provisional until the full five-year runway is complete. This is why acquirers should model the Section 72A conditions as covenants, monitor them annually, and reduce their exposure to a reversal by keeping the acquired undertaking operating at genuine capacity.

Demerger: Section 72A 4)

A demerger splits one undertaking out of a company into a separate "resulting company." Section 72A 4) governs how losses and depreciation follow the split:

• Directly relatable losses go with the undertaking. Accumulated loss and unabsorbed depreciation that are directly relatable to the undertaking transferred to the resulting company are allowed to be carried forward and set off in the hands of the resulting company.
• Common losses are apportioned by asset ratio. Where the loss or depreciation is not directly relatable to the transferred undertaking, it is apportioned between the demerged company and the resulting company in the same proportion in which the assets of the undertaking have been retained by the demerged company and transferred to the resulting company.

Unlike the amalgamation route, the demerger provisions in Section 72A 4) do not impose the Rule 9C 50% capacity condition or the Form 62 requirement, though the demerger itself must satisfy the definition in Section 2 19AA) to qualify. The Central Government may notify further conditions under Section 72A 5). Because the loss allocation turns on the asset ratio, the way assets are carved between the demerged and resulting entities directly determines how much of the loss pool each keeps. That allocation should be settled in the scheme of arrangement, not left to be argued at assessment.

Interaction With Section 79 and MAT

Two other provisions sit alongside Section 72A, and both are commonly overlooked.

Section 79: change in shareholding of closely held companies. For a company in which the public are not substantially interested (a closely held company), Section 79 restricts carry-forward of losses when shareholding changes by more than 49% of the voting power compared with the year the loss was incurred. Section 72A operates as a specific enabling provision for amalgamations, so it overrides the general Section 79 bar for losses that pass through a qualifying merger. Two caveats matter in practice. First, Section 79 does not apply to unabsorbed depreciation at all, since depreciation is governed by Section 32 2), not Section 72. Second, once the losses become the amalgamated company's own losses, a later change in that company's shareholding could attract Section 79 in its own right if it is closely held.

MAT under Section 115JB. Setting off Section 72A losses against normal taxable income does not switch off the minimum alternate tax (MAT) under Section 115JB. MAT is computed on book profit, and the book-profit computation allows only the deduction of the lower of brought-forward book loss or unabsorbed depreciation as per the books of account, which is a different figure from the income-tax loss carried under Section 72A. A company that has wiped out its normal tax liability using inherited losses can still face MAT at 14% of book profit. The MAT paid becomes MAT credit, but the cash outflow is real and must be modelled into any deal that relies on a large 72A loss pool.

Worked Example: Company A Amalgamates Into Company B

Facts. Company A owns an industrial undertaking (a components manufacturing plant) and has run it for seven years. It carries an accumulated business loss of Rs 10 crore and unabsorbed depreciation of Rs 4 crore. Company B, a profitable manufacturer, absorbs Company A in a scheme of amalgamation effective in FY 2025-26 (AY 2026-27). Company A had held more than 75% of the book value of its fixed assets continuously for the two years before the merger, so the transferor conditions in Section 72A 2)(a) are met.

Step 1: The loss pool transfers and resets. On the appointed date, the Rs 10 crore business loss and Rs 4 crore unabsorbed depreciation are deemed to be Company B's own for FY 2025-26.

Step 2: Company B sets off against its profits. Suppose Company B earns business income of Rs 6 crore in FY 2025-26. It first sets off Rs 6 crore of the inherited business loss, reducing taxable business income to nil. The remaining Rs 4 crore business loss and the full Rs 4 crore unabsorbed depreciation carry forward. In FY 2026-27, business income of Rs 7 crore absorbs the Rs 4 crore residual business loss, then the Rs 3 crore balance is reduced by unabsorbed depreciation, leaving Rs 1 crore of depreciation to carry further.

Step 3: MAT check. Even in the years where normal tax is nil, Company B tests its book profit under Section 115JB. If book profit is positive after the limited book-loss adjustment, it pays MAT at 14% (plus surcharge and cess) and banks the MAT credit. The 72A set-off shelters normal tax, not MAT.

Step 4: The five-year compliance runway. For the benefit to stand, Company B must, through to FY 2030-31: hold at least 75% of the book value of Company A's acquired fixed assets, continue the components business, run the acquired plant at 50% or more of installed capacity (reached before the end of four years), and file Form 62 with the accountant's certificate alongside each year's return. If Company B closes the plant or sells the machinery in FY 2028-29, the Rs 10 crore already set off in FY 2025-26 and FY 2026-27 becomes deemed income of FY 2028-29 under Section 72A 3), and the tax saved is reversed with interest.

The lesson from the example is that Section 72A is a five-year commitment, not a one-time entry on the appointed date. The tax value is real, but it is earned by keeping the acquired business genuinely operational.

Frequently Asked Questions

Does Section 72A apply to every merger between two companies?

No. The amalgamating company must own an industrial undertaking, a ship, or a hotel, or be a banking company merging with a specified bank, or a public sector airline company. Trading companies, investment holding companies, and many service businesses do not own an industrial undertaking, so their accumulated losses do not transfer under Section 72A even in a genuine amalgamation.

What is the carry-forward period for the loss inherited under Section 72A?

The accumulated business loss is deemed to be the loss of the amalgamated company for the year the amalgamation takes effect, so it gets a fresh eight-year carry-forward period counted from that year. Unabsorbed depreciation is different: under Section 32 2) it has no time limit and can be carried forward indefinitely.

What is Form 62 and when must it be filed?

Form 62 is a certificate, verified by an accountant with reference to the books and production records, certifying that the amalgamated company has achieved the prescribed level of production under Rule 9C. It must be filed along with the return of income for the year the 50% installed-capacity level is achieved and for each subsequent year within the five-year window. Failure to file it is a common ground for the Assessing Officer to deny the carry-forward.

What happens if the amalgamated company breaches a condition after claiming the set-off?

Under Section 72A 3), if any condition in Section 72A 2) is not complied with, the loss or depreciation already set off in the amalgamated company's hands is treated as its income and taxed in the year the breach occurs. For example, selling the acquired plant or falling below the 50% capacity level in year four can reverse benefits already claimed in earlier years, with interest exposure.

How are losses treated in a demerger under Section 72A 4)?

Accumulated loss and unabsorbed depreciation directly relatable to the transferred undertaking are carried forward by the resulting company. Losses not directly relatable are apportioned between the demerged company and the resulting company in the same proportion as the assets retained and transferred. The Rule 9C capacity and Form 62 conditions do not apply to demergers, but the demerger must satisfy Section 2 19AA).

Can the amalgamated company still be liable to MAT after using Section 72A losses?

Yes. Section 72A losses reduce normal taxable income but not book profit under Section 115JB. The book-profit computation only allows the lower of brought-forward book loss or unabsorbed depreciation as per the books, which differs from the income-tax loss. A company that pays nil normal tax using inherited losses can still owe MAT at 14% of book profit, though it earns MAT credit for the amount paid.
