Slump Sale Under Section 50B: How Selling Your Business as a Going Concern Is Taxed
Reviewed by CA Nikhil Gupta · Last reviewed 17 June 2026
When a business is sold as a whole, undertaking and all, for a single lump-sum price without putting a separate value on individual assets, the tax law treats it very differently from selling assets one by one. This is called a slump sale, and Section 50B lays down a special way of computing the capital gain.
What Qualifies as a Slump Sale?
Section 2(42C) defines a slump sale as the transfer of one or more undertakings, as a result of the sale, for a lump-sum consideration, without values being assigned to the individual assets and liabilities being transferred. The key feature is that there is no item-wise valuation; the buyer and seller agree on one price for the entire business unit, which may include factory premises, machinery, inventory, brand name, contracts, employees and outstanding liabilities, all bundled together.
If the agreement separately values individual assets, even if the overall transaction looks like a business sale, it may not qualify as a slump sale and could instead be treated as an itemised sale of assets, with each asset taxed separately under its own head (capital gains for capital assets, business income for stock-in-trade, and so on).
How the Capital Gain Is Computed
Under Section 50B, the capital gain arising from a slump sale is computed as:
How Net Worth Is Computed
- For depreciable assets (like plant and machinery), the value taken is the written down value (WDV) as per the income tax block of assets, not the book value under company accounts
- For non-depreciable assets such as land, the value is the book value as appearing in the books of account
- Liabilities are taken at their book value
- Any revaluation of assets done by the company is ignored for this computation, meaning if assets were revalued upward in the books just before the sale, that revaluation does not increase the net worth figure used for tax purposes
Holding Period: Long-Term or Short-Term?
A slump sale is always treated as a transfer of a long-term capital asset, regardless of how long individual assets within the undertaking were held, provided the undertaking itself (as a unit) has been owned and held by the seller for more than 36 months. If the undertaking has been held for 36 months or less, the gain is short-term.
Worked Example
Reporting and Valuation Requirements
For slump sales, the seller is required to obtain a report from a chartered accountant in the prescribed format (Form 3CEA) certifying the computation of net worth of the undertaking, and this report must be furnished along with the income tax return for the year in which the slump sale takes place.
Slump Sale vs Itemised Sale: Why It Matters
| Aspect | Slump Sale (Section 50B) | Itemised Sale of Assets |
|---|---|---|
| Valuation | Single lump-sum, no asset-wise split | Each asset valued and sold separately |
| Tax computation | One capital gain figure = Sale price - Net worth | Separate tax treatment per asset (capital gains, business income, depreciation recapture, etc.) |
| Holding period | Always based on how long the undertaking was held as a unit | Based on individual holding period of each asset |
| Compliance | Mandatory CA report (Form 3CEA) | No special slump sale report needed |
Why Buyers and Sellers Both Care About Structuring
Whether a business transfer is structured as a slump sale, an itemised asset sale, or a share sale (where the buyer acquires shares of the company owning the business rather than the business itself) has very different tax outcomes for both parties, and also affects stamp duty, GST treatment, and the transfer of existing contracts and licenses. This makes the structuring decision one of the most consequential parts of any business sale negotiation.
