Income Tax Implications of M&A in India: Slump Sale, Capital Gains and Section 72A

## Tax Structure Shapes the M&A Deal In India's corporate M&A market, the choice of transaction structure is rarely made purely on commercial grounds. Tax efficiency — or tax exposure — frequently determines whether a deal closes at all, and on what terms. The Income Tax Act, 1961 contains specific provisions for each of the major M&A structures, and the consequences of mischaracterising or misstating a transaction can result in reassessment, penalties, and protracted litigation with the Income Tax Department. **A note on the new Act:** The Income-tax Act, 2025 replaced the Income-tax Act, 1961 with effect from 1 April 2026. Section references below are to the 1961 Act, which continues to govern transactions in tax years up to 2025-26 and pending assessments; the 2025 Act re-enacts most of these provisions under new section numbers. This analysis covers the principal tax implications for sellers and buyers in three common M&A structures: slump sale, itemised asset sale, and share purchase. ## Slump Sale: Section 50B ### What Constitutes a Slump Sale Section 50B of the Income Tax Act, 1961, introduced in 2000, specifically governs the transfer of an "undertaking" as a going concern for a lump sum consideration, without values being assigned to individual assets and liabilities. A slump sale is characterised by: - Transfer of a business undertaking in its entirety - A single lump sum price for the whole undertaking - No individual asset-by-asset valuation in the transaction documents The Supreme Court and various High Courts have examined what constitutes an "undertaking" — it must be a self-contained, functioning business unit capable of being operated independently. A transfer of merely assets (even a large number of them) without the associated contracts, employees, and business relationships may not qualify as a slump sale. ### Capital Gains Computation Under Section 50B For a slump sale: - **Net Worth** of the undertaking replaces the "cost of acquisition" for capital gains computation - Net Worth is computed as the value of assets less liabilities as per the books, with assets valued at cost less depreciation (written-down value under the Act, not market value) - The difference between the sale consideration and the Net Worth is the capital gain - If the undertaking has been held for more than **36 months**, the gain is a Long Term Capital Gain (LTCG), taxed at 12.5% for transfers on or after 23 July 2024 (20% before that date) — indexation is not available on a slump sale; otherwise, it is a Short Term Capital Gain taxed at the seller's normal rate The compulsory use of Net Worth as the cost base — rather than market value of assets — means that undertakings with significant self-generated goodwill, IP, or land whose market value far exceeds book value will have a high capital gains exposure relative to what a buyer would see on an itemised basis. A Report from a Chartered Accountant certifying the Net Worth must be filed along with the return of income for the year of the slump sale. Failure to file the report attracts penalty under Section 271B. ## Itemised Asset Transfer: The Depreciation and Capital Gains Matrix Where a transaction is structured as a transfer of specific assets (plant and machinery, land, brand, contracts) with individual valuations, the tax treatment depends on the nature of each asset: ### Depreciable Assets: Section 50 For depreciable assets (plant, machinery, equipment) that have been subject to depreciation under the Income Tax Act, the entire gain on sale is treated as **short-term capital gain** under Section 50, regardless of the period of holding. This is because the tax base (written-down value) has already been reduced by depreciation — the asset's "effective holding period" is compressed for tax purposes. For sellers with fully depreciated equipment (WDV close to zero), the Section 50 exposure can be substantial — the entire sale consideration becomes the short-term capital gain. ### Land and Buildings: Long-Term vs Short-Term Land and buildings held for more than 24 months qualify for long-term capital gains treatment. For transfers on or after 23 July 2024, long-term gains are taxed at 12.5% without indexation. Only resident individuals and HUFs selling land or buildings acquired before that date may instead compute the gain at 20% with indexation; a corporate seller has no such option. ### Goodwill: A Post-2021 Minefield The Finance Act, 2021 removed goodwill from the definition of a depreciable asset under Section 32. The consequence: depreciation on goodwill is no longer available to the buyer who acquires an undertaking (whether by itemised sale or slump sale). For sellers, goodwill is now treated as a capital asset with cost of acquisition being the amount actually paid for it — if it is self-generated, the cost is nil, meaning the entire sale consideration attributable to goodwill is a capital gain. ## Share Purchase: Capital Gains in the Hands of the Selling Shareholders A share purchase does not disturb the target company's tax attributes — its depreciation schedule, losses, and deferred tax assets remain with the company. This is frequently the buyer's preference: they acquire the company's tax history, including carried-forward losses. For selling shareholders: - Gains on unlisted shares held for more than **24 months** are LTCG taxed at **12.5% without indexation** (post-Finance Act 2024 amendment) - Gains on listed shares/securities held for more than **12 months** are LTCG at 12.5% above Rs. 1.25 lakh threshold - Short-term gains (holding period below the threshold) are taxed at 20% for listed equity shares on which STT is paid (Section 111A) and at the seller's normal rate for unlisted shares Indirect transfers — sales of shares in a foreign company that derives its value substantially from Indian assets — are taxable in India under the look-through rule in Section 9(1)(i), introduced by the Finance Act, 2012. ## Section 72A: The Loss Carry-Forward Incentive Section 72A of the Income Tax Act, 1961 permits the amalgamated company (the surviving entity in a merger/amalgamation) to carry forward and set off the accumulated business losses and unabsorbed depreciation of the amalgamating company. This provision is a significant tax incentive for acquiring distressed companies that hold large loss pools. ### Conditions for Section 72A Benefit The amalgamation must satisfy all conditions under Section 2(1B) of the Act (which defines amalgamation for tax purposes), and additionally: - The amalgamating company must have been engaged in the same business for at least **three years** prior to the amalgamation - The amalgamated company must hold at least **75% of the book value** of fixed assets of the amalgamating company for at least five years post-amalgamation - The amalgamated company must continue the business of the amalgamating company for at least five years - The amalgamated company must satisfy such other conditions as the Board may prescribe **For demergers:** Section 72A(4) extends similar benefits to the resulting company in a demerger, subject to analogous conditions regarding the continuity of the demerged business. Failure to maintain the five-year continuity conditions results in the loss previously set off being deemed income of the amalgamated company in the year of breach — a material post-closing compliance obligation that acquirers frequently underestimate. ## Deferred Tax: AS 22 and Ind AS 12 Beyond current tax exposure, M&A due diligence must examine the target's deferred tax assets (DTA) and deferred tax liabilities (DTL) as recognised under Accounting Standard 22 or Ind AS 12 (for Ind AS-adopting companies). DTAs arise from temporary differences where the tax base of an asset or liability is higher than the accounting base — typically from: - Timing differences in depreciation (WDV under tax vs. SLM under accounts) - Provisions not yet deductible for tax purposes - Carried-forward losses (only if virtual certainty of future profits exists for recognition under AS 22 / probable for Ind AS 12) In a share purchase, the buyer acquires the DTA/DTL position of the target. In a slump sale or asset purchase, the buyer starts with a fresh tax depreciation schedule and the seller's DTA/DTL is typically extinguished. This asymmetry affects the negotiated enterprise value — buyers in share acquisitions should model the DTA realisation risk carefully, particularly for targets with large loss-based DTAs that depend on uncertain future profitability. ## Withholding Tax: Section 195 for Non-Resident Sellers Where the seller of shares or assets is a non-resident, the buyer has a withholding obligation under Section 195 of the Income Tax Act. The buyer must deduct tax at source at the applicable rate before making payment to the non-resident seller. Failure to deduct results in the buyer being treated as an "assessee in default" and liable for the tax not deducted plus interest. For cross-border M&A involving PE/VC funds or foreign strategic buyers selling Indian assets, the applicable tax rate depends on the relevant Double Taxation Avoidance Agreement (DTAA) — India has DTAAs with most major investment jurisdictions. An application for a lower withholding certificate under Section 197 is frequently filed by non-resident sellers to reduce the withholding obligation pending final tax determination.
