Special Cases of Capital Gains Computation
Updated 10 October 2026 · Fact-checked
Special cases of capital gains are transfers where the normal formula (sale price minus cost) is modified. Slump sale uses net worth as cost, a depreciable block gives a short-term gain only when sale value exceeds block WDV plus additions, and bonus shares have nil cost. Identify the case, apply its special cost rule, then compute.
Understand Special Cases of Capital Gains Computation
Normal capital gains work on one formula: full value of consideration less expenses on transfer less cost of acquisition less cost of improvement. Some transfers do not fit that formula. For them the Act gives a special rule for the cost, the consideration or the nature of the gain. Your first job in any question is to spot which case you are in.
Slump sale means selling an entire undertaking or division for a lump sum. You cannot assign cost to each asset, so the Act uses the net worth of the undertaking as its cost of acquisition and cost of improvement. If you held the undertaking for 36 months or less, the gain is short-term. Otherwise it is long-term. A report of an accountant, in the prescribed form, must be furnished before the specified date referred to in section 63. It must include the computation of net worth and certify that net worth is correctly arrived at.
Depreciable assets are handled as a block of assets. You do not compute gain asset by asset. Selling one asset from a block usually only reduces the block's written down value (WDV). A capital gain arises only when the sale value exceeds the total of transfer expenses, opening WDV and the actual cost of assets added in the year. That gain is always short-term. If every asset in the block is transferred, the block ceases to exist and the result is a short-term gain or loss.
Shares and securities carry their own cost rules. Bonus shares allotted without payment have nil cost. Rights entitlements renounced have nil cost. Shares subscribed on rights cost what you paid.
Long-term equity shares, units of equity oriented funds and business trust units acquired before 1 February 2018 get a grandfathered cost: the higher of actual cost and the lower of fair market value (FMV) and the sale consideration. FMV depends on the asset:
- Listed on 31 January 2018: the highest price quoted on that date.
- Listed, but no trading on 31 January 2018: the highest price on the immediately preceding date on which it traded.
- A unit not listed on that date: its net asset value on 31 January 2018.
- Certain equity shares not listed on 31 January 2018 (for example, listed only by the date of transfer): the cost of acquisition indexed by CII for 2017-18 ÷ CII for the first year of holding or the year beginning 1 April 2001, whichever is later.
For other capital assets that became yours before 1 April 2001, and that have no special cost rule of their own, you may take either actual cost or FMV on 1 April 2001, at your option. For land or building, the FMV on 1 April 2001 cannot exceed the stamp duty value of that date, where available.
Compulsory acquisition and conversion of a capital asset into stock in trade are special cases too. The text supplied for this page does not contain their rules on the year of taxability or the value to use. Learn them from the Income-tax Act, 2025 and your study material, and do not rely on this page for them.
Key rules to remember
- Slump sale: gain
- Capital gain = Full value of consideration − Net worth
- Net worth is deemed to be both cost of acquisition and cost of improvement. Short-term if the undertaking was held for 36 months or less, otherwise long-term (section 77).
- Net worth of undertaking
- Net worth = Aggregate value of total assets − Liabilities as per books
- Ignore any revaluation of assets. Liabilities are taken as appearing in the books (section 77(5)).
- Aggregate value of total assets
- Depreciable assets: WDV of block | Self-generated goodwill: nil | Assets fully allowed or allowable under section 46: nil | Other assets: book value
- Goodwill not acquired by purchase from a previous owner is nil. Purchased goodwill takes its book value (section 77(5)(b)).
- Block of assets: short-term gain
- Gain = Full value of consideration − (Transfer expenses + Opening WDV of block + Actual cost of assets acquired in the year)
- Applies only if the result is positive, and the gain is deemed short-term (section 74(2)).
- Block ceases to exist
- Cost of acquisition = Opening WDV + Actual cost of assets acquired during the year
- All assets of the block transferred in the tax year. The income or loss is short-term (section 74(3)).
- Bonus shares
- Cost of acquisition = nil
- For a financial asset allotted without any payment on the basis of holding another financial asset (section 90(6)(d)). The original shares cost the amount actually paid for them (section 90(6)(a)).
- Rights entitlement and rights shares
- Original shares: amount paid | Renounced right: nil | Shares subscribed: amount paid | Renouncee: price paid to renouncer + amount paid to company
- Section 90(6)(a) to (e).
- Grandfathering of equity shares
- Cost = Higher of [Actual cost, Lower of (FMV on 31 Jan 2018, Full value of consideration)]
- For long-term equity shares, units of equity oriented funds or business trust units acquired before 1 February 2018 (section 90(7)). FMV: highest quoted price on 31 January 2018; if no trading that day, the highest price on the immediately preceding traded date; for a unit not listed, its net asset value on that date. For certain equity shares not listed on 31 January 2018, FMV is cost × CII 2017-18 ÷ CII of the first year of holding or the year beginning 1 April 2001, whichever is later (section 90(8)).
- Assets held before 1 April 2001
- Cost = Actual cost or FMV on 1 April 2001, at the assessee's option
- Applies to other capital assets that became the assessee's property before 1 April 2001, not to assets with a special cost rule. For land or building, FMV on 1 April 2001 cannot exceed the stamp duty value of that date, where available (section 90(9) and (10)).
- Goodwill and similar rights
- Cost of improvement = nil | Cost of acquisition = purchase price if bought, else nil
- Applies to goodwill, trade marks, brand names, tenancy rights, stage carriage permits, loom hours and similar rights (section 90(1) and (3)).
How to solve Special Cases of Capital Gains Computation questions
Use this order for any special-case capital gains question. It keeps you from applying the normal formula where a special rule overrides it.
- 1Identify the case: slump sale, depreciable block, bonus or rights shares, pre-2001 or pre-February 2018 asset, compulsory acquisition, or conversion into stock in trade.
- 2Fix the year of taxability. For a slump sale it is the tax year in which the transfer took place, and a block gain is worked out for the tax year of the sale. For compulsory acquisition and conversion into stock in trade, use the year-of-taxability rule in the Income-tax Act, 2025 and your study material, as the supplied text does not cover it.
- 3Decide short-term or long-term. A slump sale is short-term if held for 36 months or less. Gains on a depreciable block are always short-term.
- 4Find the full value of consideration, and deduct expenses wholly and exclusively connected with the transfer.
- 5Apply the special cost rule: net worth, block WDV plus additions, nil for bonus shares, grandfathered cost, or actual cost or FMV on 1 April 2001 (for land or building, FMV capped at the stamp duty value of that date).
- 6Compute the gain or loss and show each figure on its own line.
- 7Write the conclusion in words: type of gain, year, and amount carried to the head Capital gains.
Quickest way: Case-and-cost shortcut
When to use it: Use this for MCQs and for the opening lines of a written answer when time is short.
- Slump sale: net worth = block WDV + book value of other assets − liabilities. Self-generated goodwill is nil. Then subtract net worth from consideration.
- Block of assets: add opening WDV, additions and transfer expenses. Compare the total with the sale value. If sale value is higher, the excess is a short-term gain. If lower, there is no gain.
- Bonus shares: cost is nil, so the entire sale price is the gain (after expenses).
- Rights renounced: nil cost, so the whole amount received is the gain.
- If the question says before 1 April 2001, check for the option of actual cost or FMV on that date. For land or building, FMV cannot exceed the stamp duty value of 1 April 2001. If it says before 1 February 2018 and the asset is long-term equity shares or units of the kind covered, apply the grandfathering test.
Common mistakes in Special Cases of Capital Gains Computation
Computing gain on each machine separately when a block of assets is sold.
Students apply the normal formula to every asset.
Fix: Use the block formula. Gain arises only if the sale value exceeds transfer expenses plus opening WDV plus additions during the year.
Using the book value of self-generated goodwill in net worth.
Students copy the balance sheet figure.
Fix: Goodwill not purchased from a previous owner is nil. Purchased goodwill is taken at book value.
Taking the revalued figure of assets in a slump sale.
Students forget the instruction in the section.
Fix: Ignore any change in value due to revaluation. For depreciable assets, use the WDV of the block, not the book value.
Treating gain on a depreciable block as long-term because the asset was held for years.
Students apply the holding period test.
Fix: Gain under the block rule is deemed short-term, whatever the period of holding.
Giving bonus shares a cost equal to market value on allotment.
Students confuse bonus with purchase.
Fix: Bonus shares allotted without payment have nil cost. The original shares keep their own cost.
Using the full FMV on 1 April 2001 for land or building without checking the stamp duty value.
Students remember the FMV option but forget the limit on it.
Fix: For land or building, FMV on 1 April 2001 cannot exceed the stamp duty value of that date, where available. Use the lower figure if FMV is higher.
Worked examples
Example 1
Rohan Traders sold its Pune division on 15 January 2027 for a lump sum of ₹90,00,000. The division had been held for 5 years. Books show: block of depreciable assets with WDV ₹30,00,000; other assets at book value ₹50,00,000; self-generated goodwill at ₹5,00,000 (shown after internal valuation); liabilities ₹20,00,000. Compute the capital gain, treating ₹90,00,000 as the full value of consideration.
Show the solution
- This is a slump sale. Net worth is the cost of acquisition and the cost of improvement.
- Depreciable assets: WDV of block = ₹30,00,000.
- Other assets: book value = ₹50,00,000.
- Self-generated goodwill: nil, because it was not purchased from a previous owner.
- Aggregate value of total assets = 30,00,000 + 50,00,000 + 0 = ₹80,00,000.
- Net worth = 80,00,000 − 20,00,000 = ₹60,00,000.
- Holding period is 5 years, which is more than 36 months, so the gain is long-term.
- Capital gain = 90,00,000 − 60,00,000 = ₹30,00,000.
Answer: Long-term capital gain on slump sale = ₹30,00,000. A report of an accountant certifying net worth must be furnished in the prescribed form.
Example 2
For tax year 2026-27, Meera Industries has a block of plant and machinery with opening WDV ₹8,00,000. During the year it bought a new machine for ₹1,00,000 and sold an old machine for ₹12,00,000, incurring ₹20,000 on the sale. The block continues to exist. Find the capital gain.
Show the solution
- Depreciable block rule applies. Compare the sale value with the sum of the deductible items.
- Transfer expenses = ₹20,000.
- Opening WDV of block = ₹8,00,000.
- Actual cost of asset acquired in the year = ₹1,00,000.
- Total = 20,000 + 8,00,000 + 1,00,000 = ₹9,20,000.
- Full value of consideration = ₹12,00,000, which exceeds ₹9,20,000.
- Excess = 12,00,000 − 9,20,000 = ₹2,80,000.
- Under section 74(2), this excess is deemed a gain from transfer of short-term capital assets.
Answer: Short-term capital gain = ₹2,80,000 (section 74(2)).
Exam tips
- In MCQs, read the holding period first. A 36-month rule in a slump sale and the always-short-term rule for blocks are favourite traps.
- For slump sale, write net worth as a separate working note: asset-wise list, liabilities, then net worth. Step marks sit in that note.
- Write the words 'cost of acquisition = nil' for bonus shares and renounced rights. Examiners look for that line.
- For compulsory acquisition and stock in trade conversion, learn the year-of-taxability rule from the Act and your study material, and state it before you compute.
- Show the block of assets working in four lines: sale value, expenses, opening WDV, additions. Then state the result.

Special Cases of Capital Gains Computation: frequently asked questions
What is net worth in a slump sale?
Net worth is the aggregate value of total assets of the undertaking less its liabilities as appearing in the books. For depreciable assets use the WDV of the block. Self-generated goodwill is nil, and revaluation is ignored.
Is capital gain on a block of depreciable assets long-term or short-term?
It is short-term. When sale value exceeds expenses on transfer, opening WDV and additions in the year, the excess is deemed short-term capital gain. The holding period does not matter.
What is the cost of bonus shares?
The cost of bonus shares allotted without payment on the basis of holding other shares is nil. So the whole sale price, less transfer expenses, is the gain. The original shares keep their own cost.
Can I use FMV on 1 April 2001 as the cost of land held since before that date?
Yes, at your option, instead of actual cost. But for land or building the FMV on 1 April 2001 cannot exceed the stamp duty value of that date, where available.
How is FMV found for grandfathering shares bought before 1 February 2018?
For listed shares it is the highest quoted price on 31 January 2018. If there was no trading that day, use the highest price on the immediately preceding date it traded. An unlisted unit uses its net asset value, and certain shares not listed on that date use the indexed cost. The cost is then the higher of actual cost and the lower of FMV and the sale consideration.
