The same ₹50 crore deal can leave a seller with very different amounts, depending on how it is structured. Tax considerations in an Indian M&A deal hinge on structure: share sale, asset purchase, slump sale, and merger each trigger different capital gains, GST, stamp duty, and loss carry-forward outcomes. Selling unlisted shares held over 24 months attracts 12.5% long-term capital gains tax. A slump sale is taxed on net worth versus fair market value, and merger losses can be used for the remainder of their original eight-year window. Buyers also inherit the seller’s pre-transfer GST dues.
This guide compares each structure so both sides can assess it before signing.

How Tax Treatment Differs Across Indian M&A Deal Structures?
Indian M&A tax treatment depends mainly on what is transferred: shares, individual assets, a business as a going concern, or ownership through a merger/demerger. Gains on a transfer of a capital asset are generally taxable as capital gains under Section 45. Businesses can choose from different types of mergers, depending on their ownership structure, strategic objectives, and the assets or liabilities being transferred
Buyer–seller tax comparison
| Structure | Seller’s tax | Buyer’s tax/benefit |
| Share purchase | Capital gains on shares | No asset step-up. Inherits tax history and contingent liabilities |
| Asset purchase | Capital gains or business income, asset by asset | Cost base and depreciation on actual price. Buyer picks assets and liabilities |
| Slump sale | Capital gains on net worth vs fair market value. No per-asset value | Acquires the whole undertaking for a lump sum |
| Merger/amalgamation | Tax-neutral if exemption conditions are met | May inherit losses and depreciation, subject to conditions |
| Demerger | Tax-neutral if qualifying; at least 75% of shareholders (by value) must move to the resulting company | Resulting company may carry forward linked losses and depreciation, subject to conditions |
Tax considerations in an Indian M&A deal therefore go beyond headline price: they affect capital-gains exposure, depreciation, loss carry-forwards, stamp duty, and who retains legacy liabilities.
Capital Gains Tax Implications for Buyers and Sellers
Capital gains arise when a seller transfers a capital asset for more than its tax cost; under Section 45, such gains are taxable in the year of transfer, subject to exemptions.
Holding periods and transfers
- Short-term vs long-term: The holding period determines whether the gain is short-term or long-term; listed shares generally become long-term after 12 months, while most other assets require 24 months.
- Share transfers: The seller pays capital-gains tax on the share sale. The buyer’s cost base is the purchase price, without a step-up in the target company’s asset values.
- Asset transfers: The seller may recognise capital gains or business income, depending on the asset’s nature. The buyer records the acquired asset at purchase cost, affecting future depreciation.
Tax considerations in an Indian M&A deal also include depreciation: assets are depreciated on the written-down value of a “block of assets,” so purchase-price allocation affects the buyer’s future deductions.
GST and Stamp Duty Considerations
GST usually does not apply to a share purchase, because shares are securities rather than taxable supplies. For asset or slump-sale transfers, GST may apply unless the transaction qualifies as a transfer of a going concern. It is a whole or independent part of an undertaking, where the GST law provides an exemption.
Tax considerations in an Indian M&A deal also include stamp duty. This is charged on transaction documents such as share-transfer forms, asset-transfer deeds, and merger schemes. Stamp duty rates and procedures vary by state, so the same deal can have different duty costs depending on where the documents are executed or where the assets are located.
GST and stamp duty are separate assessments: GST depends on the nature of the supply, while stamp duty depends on the instrument and applicable state law.
Tax Exemptions and Carry-Forward of Accumulated Losses
Qualifying mergers and demergers can be tax-neutral: the transfer of assets and shares may not trigger immediate capital-gains tax under Section 47 exemptions.
Under Section 72A, the resulting company may carry forward accumulated losses and unabsorbed depreciation, but only if conditions are met: the transferor must have operated the loss-making business for at least three years, held at least three-fourths of its fixed assets for two years before the transaction, and the resulting company must continue the business for at least five years.
Tax considerations in an Indian M&A deal are not automatic because eligibility depends on statutory definitions, shareholder-continuity tests, business continuity, and whether losses relate to the transferred undertaking.
Thorough tax due diligence can help buyers identify outstanding liabilities, verify eligible losses, and assess whether the target meets the required statutory conditions
Cross-Border M&A Tax Considerations in India
In cross-border deals, India may tax a foreign seller’s gain from Indian assets or shares. The Indian buyer must withhold tax under Section 195 when paying a non-resident. The applicable DTAA rate can apply if it is more beneficial and the seller provides a tax-residency certificate.
Tax considerations in an Indian M&A deal also include indirect transfers: foreign shares may be treated as situated in India if they derive substantial value from Indian assets. Related-party transactions must follow arm’s-length pricing under transfer-pricing rules.
Foreign parties need additional compliance, including lower-withholding certificates, Form 15CA/15CB, tax-residency and beneficial-ownership documentation, and transfer-pricing records.
How Tax Planning Influences M&A Negotiations and Post-Merger Integration
Tax planning shapes deal terms: sellers seek tax indemnities and warranties for pre-closing liabilities, while buyers negotiate purchase-price adjustments, escrows, and conditions tied to tax outcomes. Effective M&A negotiation strategies can help both parties allocate tax risks, agree on liability protections, and avoid disputes after closing.
Tax considerations in an Indian M&A deal also influence financing: debt interest may be deductible, but withholding tax can apply to cross-border lender payments, affecting deal cost. Employee transfers can create tax issues around gratuity, PF, ESOPs, and severance. Choosing suitable acquisition financing options can also influence the overall cost and tax efficiency of a transaction
After closing, integration must preserve tax benefits, such as carry-forward of losses under Section 72A, by maintaining required business continuity and avoiding unapproved restructuring. Clear tax governance, data migration, and compliance calendars reduce post-merger integration challenges.
Strong post-merger integration practices also help align financial reporting, compliance processes, and operational responsibilities after the transaction
Conclusion:
In M&A, structure shapes the tax bill as much as price. A share purchase, asset purchase, slump sale, merger, or demerger each changes who pays capital gains, how GST and stamp duty apply, and whether losses survive. Cross-border deals add withholding and indirect-transfer rules on top. Weighing tax considerations in an Indian M&A deal early gives both buyers and sellers room to negotiate terms, protect value, and avoid surprises after closing.
Before you finalise your next deal, map each structure’s tax outcome and review it with a qualified tax advisor.
