Slump Sale Under Section 50B: How Selling Your Business as a Going Concern Is Taxed

CA Nikhil Gupta·June 2026·8 min readIncome Tax

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:

Capital Gain = Sale Consideration (lump-sum) minus Net Worth of the undertaking transferred. The net worth here is not the market value of assets, it is a specifically defined figure: the aggregate value of total assets of the undertaking, minus the value of liabilities, as appearing in the books of account, computed in the manner prescribed under Section 50B(2).

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.

Frequently Asked Questions

Is GST applicable on a slump sale? ▼

The transfer of a business as a going concern is generally treated as a supply of services under GST, but is specifically exempted from GST under a notification covering the transfer of a going concern as a whole or an independent part thereof. However, whether a particular transaction qualifies for this exemption depends on the facts, and it is advisable to confirm the GST position separately from the income tax slump sale analysis.

Can losses of the undertaking be carried forward by the buyer after a slump sale? ▼

Carry forward of losses and unabsorbed depreciation in a slump sale generally depends on the legal form of the transaction and whether specific provisions like Section 72A (applicable to amalgamations and certain demergers) apply. A plain slump sale of a business undertaking by one entity to another does not automatically transfer the seller's brought-forward losses to the buyer; this requires careful case-specific analysis.

What if the sale agreement assigns values to some assets like land but not others? ▼

For a transaction to be treated as a slump sale under Section 2(42C), the transfer should generally be for a lump-sum consideration without values being assigned to individual assets and liabilities. If the agreement assigns specific values to even some key assets, tax authorities may examine whether the transaction truly qualifies as a slump sale or should instead be treated as a partial itemised sale, which can change the tax computation significantly.
