Slump sale under s.50B

I am selling a whole division for one lump sum. How is that gain worked out?

The Income-tax Act, 1961 was repealed on 1 April 2026. It still governs income earned up to 31 March 2026, and every proceeding about those years however late — assessment, reassessment, rectification, penalty, revision and appeal alike. Income earned from 1 April 2026 is governed by the Income-tax Act, 2025. What changed, and which Act governs your year →

I am selling a whole division for one lump sum. How is that gain worked out?

A slump sale is the transfer of an undertaking for a lump sum without assigning values to individual assets. Under s.50B the net worth of the undertaking is your cost, and since Finance Act 2021 the fair market value computed under Rule 11UAE is deemed to be the sale consideration, overriding what the parties agreed.

This is an explainer, not a judgment. It states the law in our own words, which is exactly why it needs checking. Everything below was written from the sources listed at the foot of this page, and no chartered accountant has yet signed it off. Read the source before you rely on it in a reply or an appeal.

A slump sale is the transfer of one or more undertakings for a lump sum consideration without values being assigned to the individual assets and liabilities. Finance Act 2021 widened the definition in s.2(42C) by replacing 'as a result of sale' with 'by any means'. That was a direct response to structures where an undertaking was swapped for shares or bonds and argued not to be a sale at all; the change pulls slump exchanges and failed amalgamations and demergers into the net.

Section 50B(1) fixes the character of the gain by reference to how long you held the undertaking. If the undertaking was owned and held for not more than thirty-six months immediately preceding the transfer, the gain is short-term. Otherwise it is long-term. Note that s.50B keeps its own thirty-six month test in the statutory text, notwithstanding the general two-year rule for other assets.

Cost is net worth. Section 50B(2)(i) deems the net worth of the undertaking to be the cost of acquisition and cost of improvement, and shuts out the indexation machinery in s.48. Explanation 1 defines net worth as the aggregate value of total assets less the value of liabilities as appearing in the books, and expressly ignores any change from revaluation. Explanation 2 sets the asset values: written-down value for depreciable assets, nil for self-generated goodwill (inserted in 2021) and nil for assets on which a s.35AD deduction was allowed, and book value for everything else. A negative net worth is treated as nil cost, so the entire consideration becomes gain.

The 2021 change on the other side of the equation is the bigger one. Section 50B(2)(ii) now deems the fair market value of the capital assets as on the date of transfer, computed in the prescribed manner, to be the full value of consideration. The agreed price no longer controls. Rule 11UAE prescribes the method: compute FMV1, the fair market value of the assets of the undertaking, and FMV2, the fair market value of the consideration received including non-monetary consideration, and take the higher of the two.

So the working computation is: higher of FMV1 and FMV2, less expenditure wholly and exclusively in connection with the transfer, less net worth. The result is long-term or short-term by the thirty-six month test, with no indexation in either case.

On rate, a long-term slump sale gain falls under s.112. The CBDT's own FAQs on the Budget 2024 capital gains changes state that the rate for long-term capital gains on assets generally was rationalised to 12.5% without indexation for transfers made on or after 23 July 2024. Commentary written before that change still quotes 20%, so check the transfer date before you take a rate off a chart.

Compliance is a real condition, not a formality. Section 50B(3) requires a report of an accountant as defined in s.288 in the prescribed form, certifying that net worth has been correctly computed, furnished by the due date under s.44AB. In practice that is Form 3CEA.

Why it matters

Since 2021 you can be taxed on a figure you never received, because Rule 11UAE substitutes fair market value for the negotiated price. That makes valuation work a pre-signing task, not a post-closing one. The net worth rules also mean that a business carrying large liabilities can produce negative net worth and therefore gain equal to the entire consideration, which surprises sellers who expected the liabilities to reduce the tax.

What to do

Where people go wrong

Unsettled, or not pinned down. I could not fetch a page confirming how s.50B's own thirty-six month test interacts with the shortened holding periods introduced with effect from 23 July 2024; the statutory text of s.50B(1) that I read still says thirty-six months. The applicable long-term rate for a slump sale is inferred from the CBDT's general statement that other long-term gains were rationalised to 12.5%, not from a source dealing with s.50B specifically. Rule 11UAE's notification number and date were not confirmed from a fetched source. Form 3CEA is named in commentary; the statute itself refers only to a prescribed form.
