Your company is divesting a division, selling a manufacturing unit, or restructuring a loss-making vertical. Instead of selling each asset one by one, you transfer the entire undertaking as a going concern for a lump sum. This is a slump sale - and it comes with a specific tax computation framework under Section 50B that is fundamentally different from a regular capital gains calculation.
This guide explains Section 50B in detail: how capital gains are computed using the net worth method, how FMV is determined under Rule 11UAE (FMV1 vs FMV2), when the CA audit report in Form 3CEA is required, what the GST implications are, and how the new Income Tax Act 2025 affects slump sale transactions from FY 2026-27.
What Is a Slump Sale and Why Does It Matter?
A slump sale, defined under Section 2(42C) of the Income Tax Act, 1961, is the transfer of one or more undertakings by any means for a lump sum consideration without values being assigned to individual assets and liabilities in such transfer. The key element is that the business is sold as a going concern - the buyer takes over the entire unit, including all assets, liabilities, employees, contracts, and operations.
Section 50B provides a special computation mechanism for capital gains arising from slump sales. Unlike regular capital gains where each asset is valued individually, Section 50B treats the net worth of the entire undertaking as the cost of acquisition. For businesses planning such transactions while filing ITR for capital gains, understanding this mechanism is critical to avoid assessment disputes.
The Finance Act, 2021 expanded the definition to include “transfer by any means” - covering not just cash sales but also share exchanges (slump exchanges). Rule 11UAE was simultaneously notified to prescribe FMV computation for the full value of consideration. This dual FMV test (FMV1 vs FMV2, whichever is higher) replaced the earlier practice of simply using the lump sum consideration.
Key Terms You Should Know
- Undertaking (Section 2(42C)): Includes any part of an undertaking, a unit or division, or a business activity taken as a whole. Does NOT include individual assets or liabilities that do not form a business activity.
- Net Worth (Explanation 1 to Section 50B): Aggregate value of total assets of the undertaking minus liabilities, as appearing in books of account. Revaluation of assets is ignored. Depreciable assets are taken at WDV under IT Act. Assets with 100% deduction under Section 35AD and self-generated goodwill are valued at nil.
- FMV1 (Rule 11UAE(2)): Fair market value of the capital assets transferred, computed using a formula similar to Rule 11UA: book value of assets (adjusted for jewellery, artistic work, shares, securities, and immovable property valued at FMV) minus liabilities.
- FMV2 (Rule 11UAE(3)): Fair market value of the consideration received - both monetary (cash) and non-monetary (shares, property). Non-monetary consideration is valued per Rule 11UA.
- Form 3CEA (Rule 6H): A report by a Chartered Accountant certifying that the net worth of the transferred undertaking has been correctly computed in accordance with Section 50B. Must be filed before the due date under Section 44AB.
- Going Concern (GST): A transfer of business as a going concern is exempt from GST under Schedule II read with Notification 12/2017. The buyer must file Form GST ITC-02 to transfer input tax credit.
- Slump Exchange: Transfer of an undertaking where consideration is not cash but shares or other assets. Brought within Section 50B from FY 2020-21 by Finance Act 2021.
Who Needs to Follow Slump Sale Tax Rules?
Section 50B applies to any assessee - company, LLP, firm, or individual - that transfers an undertaking or division by way of a slump sale. The following scenarios most commonly trigger compliance:
- Companies divesting a non-core business division (e.g., selling a manufacturing plant while retaining the services business)
- Conglomerates restructuring by hiving off loss-making verticals to a new entity or buyer
- Startup founders selling an entire product line or business unit to an acquirer in an M&A transaction
- Groups undertaking internal restructuring through slump exchange - transferring an undertaking in exchange for shares of the transferee company
- LLPs or partnership firms converting a division into a separate entity by transferring it as a going concern
- Private equity-backed companies selling a portfolio company’s division as part of an exit strategy

Legal Framework: Section 50B, Rule 11UAE & Related Provisions
| Provision | What It Does |
|---|---|
| Section 2(42C) | Defines “slump sale”: transfer of one or more undertakings for a lump sum without assigning individual values. Amended by Finance Act 2021 to include “transfer by any means” (covering slump exchanges). |
| Section 50B(1) | Capital gains from slump sale are chargeable as LTCG if undertaking held >36 months; STCG if ≤36 months. No indexation. |
| Section 50B(2) | Net worth = cost of acquisition. FMV per Rule 11UAE = full value of consideration. Capital Gain = FMV (higher of FMV1/FMV2) minus Net Worth. |
| Section 50B(3) | Mandatory CA report in Form 3CEA certifying net worth computation. Must be filed before Section 44AB due date. |
| Rule 11UAE(1) | FMV of capital assets = higher of FMV1 (asset-side valuation) or FMV2 (consideration-side valuation). |
| Rule 11UAE(2) - FMV1 | Formula: A+B+C+D−L (similar to Rule 11UA). A = adjusted book value; B = FMV of jewellery/art; C = FMV of shares/securities; D = stamp duty value of immovable property; L = liabilities. |
| Rule 11UAE(3) - FMV2 | Monetary consideration + FMV of non-monetary consideration (shares valued per Rule 11UA; immovable property at stamp duty value). |
| Rule 6H / Form 3CEA | Prescribed form for the CA report under Section 50B(3). Filed electronically with DSC. Due date aligned with Section 44AB. |
| Section 170 | Slump sale treated as succession of business. If seller cannot discharge tax dues, buyer may be held liable. |
How to Compute Capital Gains on a Slump Sale: Step-by-Step
- Step 1: Confirm the transaction qualifies as a slump sale. Verify: (a) an entire undertaking, unit, division, or business activity is being transferred, (b) the consideration is lump sum (cash or share exchange post-2021), (c) individual values are NOT assigned to assets and liabilities in the sale agreement. Note: assigning values solely for stamp duty purposes does not disqualify the transaction.
- Step 2: Determine the holding period. Calculate the period from the date the undertaking was set up or acquired to the date of transfer. If >36 months: LTCG (taxed at 12.5% from 23 July 2024). If ≤36 months: STCG (taxed at applicable slab rates for companies; 20% for specified financial assets).
- Step 3: Compute Net Worth (Cost of Acquisition). Net Worth = Total Assets minus Total Liabilities of the transferred undertaking, as per books of account. Key adjustments: (i) depreciable assets at WDV under IT Act (not book depreciation), (ii) revaluation gains/losses ignored, (iii) Section 35AD assets and self-generated goodwill valued at nil, (iv) if net worth is negative, cost of acquisition = zero.
- Step 4: Compute FMV1 under Rule 11UAE(2). Apply the formula: FMV1 = A+B+C+D−L, where A = adjusted book value of assets (excluding jewellery, art, shares, securities, immovable property); B = FMV of jewellery and art (registered valuer report); C = FMV of shares and securities (per Rule 11UA valuation methodology); D = stamp duty value of immovable property; L = liabilities.
- Step 5: Compute FMV2 under Rule 11UAE(3). FMV2 = Monetary consideration (cash received) + FMV of non-monetary consideration (shares received valued per Rule 11UA; immovable property at stamp duty value). In a pure cash transaction, FMV2 = cash amount.
- Step 6: Determine the Full Value of Consideration. Full Value of Consideration = higher of FMV1 or FMV2. This anti-abuse measure ensures that neither undervaluation of assets (FMV1) nor understated consideration (FMV2) can reduce the taxable gain.
- Step 7: Compute Capital Gain and file Form 3CEA. Capital Gain = Full Value of Consideration minus Net Worth minus Transfer Expenses. Obtain Form 3CEA from a CA certifying the net worth. File before the Section 44AB due date. Engage statutory audit services for integrated audit and Form 3CEA preparation.
Documents and Records Needed for Slump Sale Compliance
- Slump sale agreement / business transfer agreement (without individual asset values assigned)
- Board resolution and shareholder approval under Companies Act 2013 Section 180(1)(a) (if substantially the whole undertaking is sold)
- Audited balance sheet of the transferred undertaking as on the date of transfer
- WDV schedule of depreciable assets under Income Tax Act (block-wise)
- Registered valuer report for immovable property, jewellery, and artistic work (for FMV1 computation under Rule 11UAE)
- FMV computation workings for shares and securities held by the undertaking (per Rule 11UA)
- Stamp duty valuation certificate for immovable property
- Form 3CEA - CA-certified report on net worth computation
- FMV2 computation workings (monetary + non-monetary consideration)
- Share valuation report (if consideration is in shares - slump exchange)
- Form GST ITC-02 (for transfer of input tax credit to buyer in going concern transfer)
- Previous ITR acknowledgements and assessment orders (for accumulated loss carry-forward verification)
Slump Sale vs Itemised Sale: Tax Impact Comparison
Choosing between a slump sale and an itemised sale significantly affects the total tax outgo. The following table highlights the key differences:
| Parameter | Slump Sale (Section 50B) | Itemised Sale |
|---|---|---|
| What is sold | Entire undertaking as a going concern | Individual assets sold separately |
| Valuation | Lump sum - no individual values assigned | Each asset individually valued |
| Cost of acquisition | Net worth of the undertaking | Individual cost of each asset |
| Depreciable assets | Part of net worth - may attract LTCG at 12.5% if held >36 months | Always STCG under Section 50 (block of assets) - taxed at slab rates (up to 30% for companies) |
| Indexation | Not available | Available for non-depreciable LTCA (pre-July 2024 property: transitional option) |
| GST | Nil if going concern | GST applicable on each asset at respective rates |
| Audit requirement | Form 3CEA mandatory | No specific audit form (but tax audit Form 3CD may cover) |
| Tax advantage | Often lower total tax - depreciable assets attract LTCG rate instead of higher STCG rate | Higher total tax - depreciable assets always STCG; each asset taxed separately |
Note: The primary tax advantage of a slump sale is that depreciable assets (machinery, vehicles, equipment) that would be taxed as STCG at up to 30% in an itemised sale can attract LTCG at 12.5% if the undertaking is held for more than 36 months. For a manufacturing company with Rs 50 crore in depreciable assets, this difference alone can save several crores in tax.
Common Mistakes to Avoid in Slump Sale Transactions
Mistake 1: Assigning individual values to assets in the sale agreement. If the slump sale agreement assigns specific values to individual assets (e.g., “land - Rs 10 crore, machinery - Rs 5 crore”), the transaction may be reclassified as an itemised sale, losing Section 50B benefits. Values assigned solely for stamp duty, registration, or similar statutory purposes are explicitly permitted and do not disqualify the transaction.
Mistake 2: Using book depreciation instead of WDV under IT Act for net worth. Depreciable assets must be taken at Written Down Value as per Income Tax Act depreciation schedules, not as per Companies Act / Ind AS depreciation. Using book value overstates net worth and understates the capital gain, leading to reassessment additions.
Mistake 3: Including revalued asset values in net worth computation. Explanation 1 to Section 50B explicitly states that any change in value on account of revaluation shall be ignored. If the company revalued its land from Rs 5 crore to Rs 30 crore in the books, the net worth must use the original Rs 5 crore. Ignoring this is a common audit trigger.
Mistake 4: Not filing Form 3CEA before the Section 44AB due date. Form 3CEA must be filed online with DSC before the due date referred to in Section 44AB (30 September for non-transfer-pricing cases; 30 November for international transactions). Late filing attracts penalty under Section 271B (1.5% of turnover or Rs 1.5 lakh, whichever is less). Taxpayers should engage statutory audit services early to avoid last-minute compliance failures.
Mistake 5: Ignoring Rule 11UAE and using actual consideration as full value. Post-2021, the full value of consideration is the higher of FMV1 (asset-side) or FMV2 (consideration-side) under Rule 11UAE - not the actual lump sum paid. If the FMV1 of assets exceeds the cash consideration, the higher FMV1 is deemed as the sale consideration. This catches below-market-value transactions.
Penalties for Non-Compliance with Slump Sale Provisions
Incorrect computation or non-compliance with slump sale provisions triggers multiple penalty provisions.
Under Section 271B, failure to furnish Form 3CEA before the prescribed due date attracts a penalty of 1.5% of total sales/turnover/gross receipts of the business, or Rs 1,50,000, whichever is less. For a company with Rs 100 crore turnover, the penalty could be up to Rs 1.5 lakh.
Under Section 270A, if the capital gain is underreported due to incorrect net worth computation (e.g., using revalued figures, book depreciation instead of WDV, or ignoring Rule 11UAE FMV), a penalty of 50% of tax payable on the underreported amount is levied. If classified as misreporting, the penalty is 200%.
Under Section 170, a slump sale is treated as succession of business. If the seller cannot pay the tax liability arising from the slump sale, the Income Tax Department can recover the outstanding amount from the buyer. This makes the buyer’s due diligence on the seller’s tax compliance critical before closing.
How Slump Sale Provisions Connect with Other Tax Laws
Section 50B operates at the intersection of multiple tax provisions. The computation uses Section 48 as the base framework (full value of consideration minus cost of acquisition minus cost of improvement minus transfer expenses), with Section 50B overriding the cost of acquisition (net worth) and the full value of consideration (Rule 11UAE FMV). For GST purposes, a slump sale as a going concern attracts nil rate under Schedule II read with Notification 12/2017-Central Tax (Rate). The buyer must file GST return filing including Form GST ITC-02 to transfer the seller’s accumulated ITC.
On the buyer side, the purchase price is allocated across acquired assets based on a registered valuer’s report. If the lump sum exceeds net asset value, the excess is recorded as goodwill. If it’s lower, the difference is recorded as capital reserve. The buyer can claim depreciation on depreciable assets at the allocated values. Accumulated business losses and unabsorbed depreciation of the transferred undertaking remain with the seller - they do NOT transfer to the buyer (unlike an amalgamation under Section 72A).
The Income Tax Act, 2025 (effective 1 April 2026) retains the slump sale framework under restructured section numbers. The substantive provisions of Section 50B, Rule 11UAE, and Form 3CEA remain unchanged. However, ITR forms for FY 2026-27 will reference new sections under the consolidated Act.
Seller Tax vs Buyer Tax in a Slump Sale
| Aspect | Seller | Buyer |
|---|---|---|
| Tax head | Capital gains under Section 50B | No immediate tax liability |
| Computation | FMV (Rule 11UAE) minus Net Worth | N/A - buyer records assets at valuer-allocated values |
| LTCG rate | 12.5% (if held >36 months) | N/A |
| Section 56(2)(x) | Not applicable to seller | Generally not applicable to slump sales (undertaking, not individual property) |
| Depreciation | Apportioned for days used before transfer | Claimed on allocated values from transfer date |
| TDS | No TDS obligation on buyer in slump sale | Not required to deduct TDS (no Section 194IA applicability) |
| GST | Nil if going concern | File Form GST ITC-02 to receive ITC transfer |
| Accumulated losses | Remain with seller (carry-forward available) | Do NOT transfer to buyer (unlike amalgamation) |
Key Takeaways
A slump sale under Section 50B treats the entire undertaking as a single capital asset, with net worth as the cost of acquisition and FMV under Rule 11UAE (higher of FMV1 or FMV2) as the full value of consideration. No indexation is available.
The primary tax advantage of a slump sale over an itemised sale is that depreciable assets - which always attract STCG at slab rates in an itemised sale under Section 50 - can qualify for LTCG at 12.5% if the undertaking is held for more than 36 months.
Rule 11UAE, notified by CBDT in May 2021, introduced the dual FMV test (FMV1 = asset-side valuation; FMV2 = consideration-side valuation). The higher of the two is deemed as the full value of consideration, preventing undervaluation in below-market transactions.
Form 3CEA is a mandatory CA-certified report verifying the net worth computation. It must be filed electronically with DSC before the Section 44AB due date. Non-filing attracts a penalty under Section 271B.
For GST purposes, a slump sale as a going concern attracts nil rate of GST. The buyer must file Form GST ITC-02 to receive the seller’s accumulated input tax credit. Under Section 170, if the seller defaults on tax payments arising from the slump sale, the buyer may be held liable - making pre-transaction tax due diligence essential.
Need Help with Slump Sale Tax Computation?
Slump sale transactions involve complex computations - dual FMV calculation under Rule 11UAE, net worth determination with WDV adjustments, Form 3CEA preparation and filing, GST going concern classification, and buyer-side asset allocation by registered valuer. A miscalculation in any of these steps can trigger reassessment, penalty under Section 270A, or recovery from the buyer under Section 170.
