484 Savings banks: exemption from tax

(1) Any savings bank other than a savings bank which is the successor or further successor to an existing trustee savings bank shall on making a claim be entitled to exemption from income tax and corporation tax in respect of the income of its funds to the extent that such income is applied in the payment or credit of interest to any depositor; but, subject to section 325, any such interest shall be chargeable under Case III of Schedule D.

(2) Any gain or loss accruing to a savings bank which is the successor to an existing trustee savings bank on a disposal of an exempt investment held by that existing bank on 21st November 1979, may, if that existing bank has so elected, be computed by reference to the cost of the investment instead of by reference to its market value on the latter date and, in the case of a loss, without any restriction under section 270(4) of the 1970 Act.

(3) In subsection (2) above the reference to an election is a reference to an election under paragraph 2(3) of Schedule 11 to the [1980 c. 48.] Finance Act 1980 (under which the election must have been by notice in writing given to the Board within two years after 21st November 1979, and has effect in relation to all exempt investments held by the bank on that date).

(4) Where a savings bank which is the successor to an existing trustee savings bank holds investments which include both exempt investments held by the existing bank on 21st November 1979 and other investments of the same class, any investments of that class which are disposed of by the successor shall be treated for the purposes of subsection (2) above as consisting of the other investments rather than of the exempt investments held on that date.

(5) In this section references to exempt investments held by an existing trustee savings bank on 21st November 1979 are to investments on the disposal of which immediately before that date no chargeable gain or allowable loss would have accrued to the bank by virtue of section 67 of the 1979 Act (gilt-edged securities held for more than a year).

(6) In this section “successor” and “existing”, in relation to a trustee savings bank, have the meanings given by section 1 of the [1985 c. 58.] Trustee Savings Bank Act 1985, and “further successor” has the meaning given by paragraph 9 of Schedule 2 to that Act.

485 Savings banks: supplemental

(a) any exempt investment which was held on that date by the first bank and was transferred with the business shall be treated for the purposes of section 484 in its application to any savings bank which is the successor to the second bank as if it had been held on that date by the second bank but without prejudice to any election made in respect of the investment by the first bank under sub-paragraph (3) of paragraph 2 of Schedule 11 to the [1980 c. 48.] Finance Act 1980; and

(b) the cost of the investment shall be taken for the purposes of that sub-paragraph as equal to the cost of the investment to the first bank.

(a) was transferred to it with the business; and

(b) was an exempt investment on the date of the transfer,

shall be taken for the purposes of section 484(2) in its application to any savings bank which is the successor to the second bank as equal to the cost of the investment to the first bank.

(3) In this section references to exempt investments held by a trustee savings bank on 21st November 1979 or the date of the transfer are to investments on the disposal of which immediately before that date no chargeable gain or allowable loss would have accrued to the bank by virtue of section 67 of the 1979 Act (gilt-edged securities held for more than a year) or, in the case of a transfer which took place before that section came into force, section 41 of the [1969 c. 32.] Finance Act 1969 (which was re-enacted by section 67 of the 1979 Act).

(a) for all purposes of income tax, and

(b) for the purposes of the charge of corporation tax on income,

the disposal of the oil and its acquisition by the person to whom it was disposed of shall be treated as having been for a consideration equal to the market value of the oil as so taken into account under section 2 of that Act (or as would have been so taken into account under that section but for section 10 of that Act).

(2) Where a person makes a relevant appropriation of any oil without disposing of it and does so in circumstances such that the market value of that oil in a particular month falls to be taken into account under section 2 of the 1975 Act in computing for the purposes of petroleum revenue tax the assessable profit or allowable loss accruing to him in any chargeable period from an oil field (or would so fall but for section 10 of that Act), then for all the purposes of income tax and for the purposes of the charge of corporation tax on income, he shall be treated—

(a) as having, at the time of the appropriation—

(i) sold the oil in the course of the separate trade consisting of activities falling within section 492(1)(a) or (b); and

(ii) bought it in the course of the separate trade consisting of activities not so falling; and

(b) as having so sold and bought it at a price equal to its market value as so taken into account under section 2 of the 1975 Act (or as would have been so taken into account under that section but for section 10 of that Act).

In this subsection “relevant appropriation” has the meaning given by section 12(1) of the 1975 Act.
