A slump sale is taxed as a single capital gain on the transfer of a whole business undertaking for one lump sum price, with the gain equal to the fair market value of the assets transferred minus the undertaking’s net worth. Long-term gains, where the business was held for more than 36 months, are taxed at 12.5%; shorter holdings are taxed at the seller’s normal income tax rate. The rules sit in Section 50B of the Income Tax Act, 1961, and carry forward under Section 77 of the Income Tax Act, 2025, which takes effect on April 1, 2026.1PIB. Understanding The Income Tax Act, 2025
What Qualifies as a Slump Sale
Section 2(42C) defines a slump sale as the transfer of one or more undertakings for a lump sum, where no values are assigned to the individual assets and liabilities in the sale agreement.2Indian Kanoon. Income Tax Act, 1961 – Section 50B Two conditions have to be met together. The transfer must cover an entire business unit, division, or identifiable business activity; cherry-picking specific assets while leaving others behind disqualifies it. And the price must be a single figure for the whole unit, not an allocation across individual machines, buildings, or receivables inside the agreement itself.
“Undertaking” is broad enough to include a division, a product line, or any self-contained business activity. It does not cover random asset bundles that don’t together function as a business. If the tax authorities find that individual values drove the negotiation, or that the transfer left out core components of the unit, they can reclassify the deal as an ordinary asset sale with very different tax consequences.
Parties sometimes list asset values in schedules for stamp duty registration or accounting handover. That alone doesn’t spoil the sale, provided those values did not determine the overall price. The lump sum must be a genuine price for the business as a whole, not reverse-engineered from a sum of parts.
How Net Worth Is Calculated
Net worth acts as the seller’s cost of acquisition. The formula is set out in Section 50B and now Section 77(5) of the 2025 Act.3Income Tax Department. Section 77 – Income Tax Act, 2025 It is the value of the unit’s assets minus its liabilities as they appear in the books, using specific valuation rules rather than market prices:
- Depreciable assets take the written-down value of the relevant block under the tax records, not book value or replacement cost.
- Self-generated goodwill is valued at zero.
- Capital assets whose entire cost has already been claimed as a deduction are also valued at zero.
- All other assets take their book value as recorded in the accounts.
Any revaluation of assets in the books must be ignored.2Indian Kanoon. Income Tax Act, 1961 – Section 50B If land was revalued upward from its original cost to current market value, the calculation still uses the original book value. This stops sellers from inflating the cost base to shrink the gain.
If the liabilities exceed the asset values and net worth comes out negative, the cost of acquisition is treated as zero. The entire lump sum then becomes taxable capital gain, which can produce a substantial bill even when the sale price looks modest against the scale of the business.
Fair Market Value Is the Sale Price
A 2021 amendment changed what counts as the “sale price” for tax purposes. Under Section 50B(2) of the 1961 Act, now Section 77(3)(b) of the 2025 Act, the fair market value of the capital assets on the date of transfer is deemed to be the full value of consideration, regardless of what the buyer actually paid.3Income Tax Department. Section 77 – Income Tax Act, 2025
Rule 11UAE of the Income Tax Rules sets the computation. Two figures are worked out: the fair market value of the assets being sold, and the fair market value of the consideration received (including any non-monetary consideration). The higher of the two becomes the deemed sale price for capital gains. That rule prevents related parties or group companies from structuring below-market transfers to save tax, and it applies equally to arm’s-length deals between unrelated parties. Getting a professional valuation done early avoids surprises at assessment.
Tax Rate and Holding Period
Capital gain equals the deemed consideration minus net worth minus any transfer expenditure. The rate depends on how long the seller held the undertaking.4Income Tax Department. Capital Gain
- Held for more than 36 months: long-term capital gain, taxed at 12.5% plus applicable surcharge and cess, with no indexation benefit.3Income Tax Department. Section 77 – Income Tax Act, 2025
- Held for 36 months or less: short-term capital gain, taxed at the normal income tax rate applicable to the seller. For companies, that is the applicable corporate tax rate.4Income Tax Department. Capital Gain
The absence of indexation matters. Long-term gains on many other assets can be adjusted for inflation; slump sales cannot. Net worth stays frozen at its book-value figure however many years of inflation elapsed since the assets were acquired, which for older undertakings can push the taxable gain higher than sellers expect.
Some relief is available. Sellers can claim reinvestment exemptions under Sections 54 to 54GB where the independent conditions for those exemptions are met. These carry strict timelines and reinvestment requirements, so the use of sale proceeds needs planning before closing, not after.
Why Sellers Choose a Slump Sale Over an Itemized Sale
In an itemized sale, every depreciable asset produces a short-term capital gain regardless of holding period, because gains on block assets are always short-term under the code. Short-term gains attract the seller’s full income tax rate. A slump sale treats the whole undertaking as a single capital asset, so if the business was held for more than 36 months, even the depreciable assets inside it contribute to a long-term gain taxed at 12.5%. That is where most of the practical tax savings come from.
Itemized sales also force separate valuations and negotiations for each asset, each potentially attracting different GST rates. A slump sale collapses that into one transfer, one gain calculation, and one GST treatment.
GST on the Transfer
A slump sale of a whole business as a going concern attracts a nil GST rate under Notification No. 12/2017-Central Tax (Rate), which exempts “services by way of transfer of a going concern, as a whole or an independent part thereof.”5GST Council. Authority for Advance Ruling – Andhra Pradesh The advantage over an itemized asset sale, where each asset transfer would attract GST at its own rate, is considerable.
The exemption is not automatic. The business must be capable of continuing operations after the transfer. An Authority for Advance Ruling in Andhra Pradesh held that excluding liabilities from the transfer disqualified a transaction from the going concern exemption, because a going concern carries both assets and the obligations attached to them. Sellers relying on nil GST should include all liabilities of the undertaking in the transfer, not only the assets.
Documents and Approvals
Business Transfer Agreement
The core document is the Business Transfer Agreement. It sets the lump sum price, defines the boundaries of the undertaking, and governs the handover. Detailed schedules should list every asset, liability, contract, employee, license, and permit being transferred; they define what the buyer is getting and provide the foundation for the net worth calculation. Missing items in the schedules cause disputes at handover and can expose the buyer to claims on assets that were supposed to move but didn’t.
Employee clauses need particular care. The agreement should address seniority, accrued leave balances, gratuity, and provident fund accounts. Ambiguity here becomes a labor dispute neither party budgeted for.
Board and Shareholder Approvals
Under Section 180(1)(a) of the Companies Act, 2013, the board of a company cannot dispose of the whole or substantially the whole of an undertaking without shareholder approval by special resolution, which needs at least 75% of votes cast. Listed companies must also comply with SEBI disclosure and listing requirements, including exchange intimation and any open offer obligations if control changes.
Form 3CEA (Form 28 under the 2025 Act)
Every seller must obtain a report from a practicing Chartered Accountant in Form 3CEA, renumbered Form 28 under the 2025 Act. The report certifies that net worth has been computed in accordance with the statutory formula.6Income Tax Department. Form 3CEA It has to be filed electronically on the income tax e-filing portal by the due date for filing the seller’s income tax return.7Income Tax Department. Form No 28 – Form No 3CEA Missing that deadline invites scrutiny at assessment and can delay processing of the return.
Stamp Duty
Stamp duty on the BTA varies by state and by how the agreement is characterized. If it transfers only movable property, many states treat it as a simple agreement and charge a nominal flat fee. If it also transfers immovable property like land or buildings without a separate conveyance deed, the agreement can be reclassified as a conveyance and attract conveyance rates, which are substantially higher.
State provisions differ. Maharashtra has distinct rates under the Bombay Stamp Act for agreements creating rights with monetary value. Karnataka charges 3% on movable property transfers where possession is delivered. Other states fall back to residuary rates under the Indian Stamp Act, 1899. Because stamp duty can add meaningfully to deal cost, parties commonly negotiate who bears it, and the place of execution can move the number.
CCI and Other Regulatory Clearances
Larger slump sales need prior approval from the Competition Commission of India. A transaction exceeding INR 2,000 crore in deal value (roughly $238 million) triggers the CCI’s deal value threshold if the target has substantial Indian operations. The CCI’s asset and turnover thresholds apply separately based on the combined figures of the parties. A de minimis exemption spares deals where the target has turnover below INR 1,250 crore or assets below INR 450 crore.
Failing to notify when required can bring penalties and an order to unwind the transaction. Cross-border deals or listed entities may need additional SEBI or Reserve Bank of India approvals. CCI review can take 30 to 210 days depending on complexity, and closing cannot happen until clearance is in hand, so the approval timeline needs mapping before signing.
The 2025 Act Transition
The Income Tax Act, 2025 consolidates and replaces the 1961 Act with effect from April 1, 2026.1PIB. Understanding The Income Tax Act, 2025 The substance of slump sale taxation carries forward under Section 77 with the same net worth formula, the same 36-month holding period, and the same fair market value deemed consideration rule.3Income Tax Department. Section 77 – Income Tax Act, 2025 The main shift is terminology: “previous year” becomes “tax year,” and cross-references point to new section numbers. Slump sales that close in the financial year starting April 2026 will file under the new Act; deals closed before that date stay under the 1961 provisions.
