Section 77 of the Income-tax Act, 2025

Section 77 — Special provision for computation of capital gains in case of slump sale. Successor to s.50B of the 1961 Act.

Where this section sits

Section 77 is in Chapter IV — Computation of Total Income, which runs from section 13 to section 95.

← Section 76  ·  Section 78 →

What this section does

Sub-section (1) charges profits or gains from a slump sale effected in the tax year as long-term capital gains, deemed income of the year of transfer, subject to sub-section (2), which treats them as short-term where the undertaking or division was owned and held for thirty-six months or less immediately before the date of transfer.

Sub-section (3) supplies both ends of the computation: net worth is deemed to be the cost of acquisition and the cost of improvement for sections 72 and 73, and the fair market value of the capital assets on the date of transfer, calculated in such manner as may be prescribed, is deemed to be the full value of the consideration. Sub-section (4) requires every assessee in a slump sale to furnish a report of an accountant in the prescribed form before the specified date referred to in section 63, including the computation of net worth and certifying that it has been correctly arrived at.

Sub-section (5) defines net worth as the aggregate value of total assets reduced by the value of liabilities as appearing in the books, any change in value due to revaluation being ignored. The aggregate value of total assets is the block written down value under section 41(1)(c) for depreciable assets; nil for goodwill not acquired by purchase from a previous owner; nil for capital assets whose entire expenditure has been allowed or is allowable under section 46; and book value for other assets.

Why it is there

A slump sale transfers an undertaking for a lump sum with no values assigned to individual assets, so the ordinary capital gains machinery has neither a cost nor an itemised consideration to work from. The section supplies both by statute and fixes the character of the gain by how long the undertaking was held rather than each asset within it. The nil valuations and the exclusion of revaluation stop net worth being inflated by amounts that never carried a tax cost.

Who it applies to

The figures, and what each one turns on

Read the condition in the same row. A figure quoted without it is a wrong answer with a citation attached.

What this means in practice

The consideration you agreed is not the consideration you are taxed on — sub-section (3)(b) substitutes the prescribed fair market value of the capital assets on the date of transfer, so a lump sum below that value does not reduce the gain. Net worth is equally statutory, not accounting: block written down value for depreciable assets, nil for self-generated goodwill and section 46 assets, book value for the rest, and revaluation ignored. Because net worth is deemed to be both cost of acquisition and cost of improvement, there is nothing further to add to cost. The thirty-six month test applies to the undertaking as the capital asset, so a young division holding old assets still yields a short-term gain.

An example

Illustrative only, and invented for this page. The figures are chosen to show the rule biting, not taken from any real matter.

A company sells a manufacturing division for a lump sum of Rs. 50 crore. Its assets are plant at a block written down value of Rs. 18 crore, other assets at book value of Rs. 12 crore, and self-generated goodwill carried at Rs. 6 crore, against liabilities of Rs. 8 crore. Net worth is 18 + 12 + 0 – 8, that is Rs. 22 crore, the goodwill entering at nil. If the prescribed fair market value of the capital assets on the date of transfer is Rs. 55 crore, the gain is Rs. 33 crore and not Rs. 28 crore, and it is long-term unless the division was held for thirty-six months or less.

Where you meet this section

You meet this section through the accountant's report on net worth that sub-section (4) makes compulsory in every slump sale, furnished in the prescribed form before the specified date referred to in section 63. It surfaces again when an Assessing Officer tests the prescribed fair market value or the composition of net worth certified in that report.

The words themselves

for computing net worth, any change in the value of assets due to revaluation shall be ignored

What people get wrong

What this replaced

The correspondence is the Income Tax Department’s own, from its comparison utility for the 1961 and 2025 Acts. A renumbering is the easy half; whether the words changed is the half that decides cases.

Rules that serve this section

Rules of the Income-tax Rules, 2026 that work section 77. Where the rule’s own heading names the section we say so; the rest are marked on reading the rule, which is our derivation and not the department’s. A rule that serves the section silently and that we have missed will not appear here.

All of them are in the Rules 2026 index.

Notifications that reach this section

A notification is made under a power the Act gives and, within that power, is law. These too were made under the 1961 Act and are placed here by the department’s concordance.

See the notifications index.

Case law carried across

Read this before you rely on it. Every decision below was decided under the Income-tax Act, 1961. It appears here because it is tagged to a 1961 provision that the department’s own mapping carries to section 77. That is an inference we have drawn, not a holding on the new section: where the words changed in the move, the reasoning may not survive. Treat this as the place to start looking, not as authority on the 2025 Act.
