[12B. Capital gains.—(1) The tax shall be payable by an assessee under the head "Capital gains" in respect of any profits or gains arising from the sale, exchange, relinquishment or transfer of a capital asset effected after the 31st day of March, 1956, and such profits and gains shall be deemed to be income of the previous year in which the sale, exchange, relinquishment or transfer took place: Provided that any distribution of capital assets on the total or partial partition of a Hindu undivided family or under a deed of gift, bequest or will shall not for the purposes of this section be treated as a sale, exchange, relinquishment or transfer of the capital assets:
Provided further that the transfer of a capital asset by a company to a subsidiary company, the whole of the share capital of which is held by the parent company or by the nominees thereof, shall not be treated as a sale, exchange or transfer within the meaning of this section where the subsidiary company is resident in the taxable territories and is registered under the Indian Companies Act, 1956, so however that for the purposes of clause (vi) or clause (vii) of sub-section (2) of section 10, the cost or the written down value, as the case may be, of the transferred capital asset shall be taken to be the same as it would have been if the parent company had continued to hold the capital asset for the purposes of its business.
(2) The amount of a capital gain shall be computed after making the following deductions from the full value of the consideration for which the sale, exchange, relinquishment or transfer of the capital asset is made, namely:—
Provided that where a person who acquires a capital asset from the assessee, whether by sale, exchange, relinquishment or transfer, is a person with whom the assessee is directly or indirectly connected, and the Income-tax Officer has reason to believe that the sale, exchange, relinquishment or transfer was effected with the object of avoidance or reduction of the liability of the assessee under this section, the full value of the consideration for which the sale, exchange, relinquishment or transfer is made shall, with the prior approval of the Inspecting Assistant Commissioner of Income-tax, be taken to be the fair market value of the capital asset on the date on which the sale, exchange, relinquishment or transfer took place:
Provided further that where the capital asset is an asset in respect of which the assessee has obtained depreciation allowance in any year, the actual cost of the asset to the assessee shall be its written down value, as denned in section 10, increased or diminished, as the case may be, by any adjustment made under clause (vii) of sub-section (2) of that section:
Provided further that where the capital asset became the property of the assessee, or of the previous owner where the cost of the capital asset to the previous owner is to be taken in accordance with sub-section (3), before the 1st day of January, 1954, he may, on proof of the fair market value thereof on the said date to the satisfaction of the Income-tax Officer, substitute for the actual cost such fair market value which shall be deemed to be the actual cost to him of the asset, and which shall be reduced by the amount of depreciation, if any, allowed to the assessee after the said date and increased or diminished, as the case may be, by any adjustment made under clause (vii) of sub-section (2) of section 10:
Provided further that where the capital asset was on any previous occasion the subject of negotiations for its sale, exchange, relinquishment or transfer, any option or other money received and retained by the assessee in respect of such negotiations shall be deducted in computing the actual cost to him of such asset.
(3) Where any capital asset became the property of the assessee by succession, inheritance or devolution or on any distribution of capital assets on the total or partial partition of a Hindu undivided family or on the dissolution of a firm or other association of persons or on the liquidation of a company or under a deed of gift, or transfer on irrevocable trust, its actual cost allowable to him for the purposes of this section shall be its actual cost to the previous owner thereof, and the provisions of sub-section (2) shall apply accordingly; and where the actual cost to the previous owner cannot be ascertained, the fair market value at the date on which the capital asset became the property of the previous owner shall be deemed to be the actual cost thereof:
Provided that where the capital asset became the property of the assessee—
(4) Notwithstanding anything contained in sub-section (1)—
Provided that this clause shall not apply in any case where the aggregate of the fair market values of all capital assets, being property the income of which is chargeable under section 9, owned by the assessee immediately before the sale, exchange or transfer aforesaid is made, exceeds the sum of rupees fifty thousand;
