(1) Subject to subsection (2) below, any income which by virtue or in consequence of any disposition made, directly or indirectly, by any person (other than a disposition made for valuable and sufficient consideration), is payable to or applicable for the benefit of any other person for a period which cannot exceed six years shall be deemed for all the purposes of the Income Tax Acts to be the income of the person, if living, by whom the disposition was made, and not to be the income of any other person.
(2) Subsection (1) above shall not apply in relation to income which is payable as a covenanted payment to charity.
(3) In this Chapter, unless the context otherwise requires—
“disposition” includes any trust, covenant, agreement or arrangement, and
“a covenanted payment to charity” means a payment made under a covenant made otherwise than for consideration in money or money’s worth in favour of a body of persons or trust established for charitable purposes only whereby the like annual payments (of which the payment in question is one) become payable for a period which may exceed three years and is not capable of earlier termination under any power exercisable without the consent of the persons for the time being entitled to the payments.
(4) For the purposes of subsection (3) above the Trustees of the National Heritage Memorial Fund and the Historic Buildings and Monuments Commission for England shall each be treated as a body of persons established for charitable purposes only.
(1) Where, by virtue of this Chapter, any income tax becomes chargeable on and is paid by the person by whom a disposition was made, that person shall be entitled—
(a) to recover from any trustee or other person to whom the income is payable by virtue or in consequence of the disposition the amount of the tax so paid; and
(b) for that purpose to require an inspector to furnish to him a certificate specifying the amount of the income in respect of which he has so paid tax and the amount of the tax so paid;
and any certificate so furnished shall be conclusive evidence of the facts appearing thereby.
(2) Where any person obtains in respect of any allowance or relief a repayment of income tax in excess of the amount of the repayment to which he would but for the provisions of this Chapter have been entitled, an amount equal to the excess shall be paid by him to the trustee or other person to whom the income is payable by virtue or in consequence of the disposition, or, where there are two or more such persons, shall be apportioned among those persons as the case may require.
If any question arises as to the amount of any payment or as to any apportionment to be made under this subsection, that question shall be decided by the General Commissioners whose decision thereon shall be final.
(3) Subject to section 833(3), any income which is deemed by virtue of this Chapter to be the income of any person shall be deemed to be the highest part of his income.
(1) In the case of any disposition where there is more than one person who made the disposition, this Chapter shall, subject to the provisions of this section, have effect in relation to each person who made the disposition as if he were the only person who had made it.
(2) In the case of any such disposition, references in this Chapter to income payable or applicable by virtue or in consequence of the disposition include, in relation to any person making the disposition, only—
(a) income from property which that person has provided directly or indirectly for the purposes of the disposition (“the settled property”); and
(b) income from property representing the settled property; and
(c) income from so much of any property which represents both the settled property and other property as, on a just apportionment, represents the settled property; and
(d) income provided directly or indirectly by that person.
(3) In this section references to property which represents other property include references to property which represents accumulated income from that other property.
(1) Where, by virtue or in consequence of any settlement to which this Chapter applies and during the life of the settlor, any income is paid to or for the benefit of a child of the settlor in any year of assessment, the income shall, if at the time of the payment the child was unmarried and below the age of 18, be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year and not as the income of any other person.
(2) Where an offshore income gain (within the meaning of Chapter V of Part XVII) accrues in respect of a disposal of assets made by a person holding them as trustee for a person who would be absolutely entitled as against the trustee but for being an infant, the income which by virtue of section 761(1) is treated as arising by reference to that gain shall for the purposes of this Chapter be deemed to be paid to the infant; and in this subsection, in relation to Scotland, “infant” means pupil or minor.
(3) This Chapter applies to every settlement, wheresoever it was made or entered into, and whether it was made or entered into before or after the passing of this Act, except a settlement made or entered into before 22nd April 1936 which immediately before that date was irrevocable.
Paragraph 10 of Schedule 30 shall have effect as respects certain earlier settlements on children.
(4) Income paid to or for the benefit of a child of a settlor shall not be treated as provided in subsection (1) above for any year of assessment in which the aggregate amount of the income paid to or for the benefit of that child, which, but for this subsection, would be so treated by virtue of subsection (1) above, does not exceed £5.
(5) This Chapter shall not apply in relation to any income arising under a settlement in any year of assessment for which the settlor is not chargeable to income tax as a resident in the United Kingdom, and references in this Chapter to income shall be construed accordingly.
(1) Subject to the provisions of this section, for the purposes of this Chapter—
(a) income which, by virtue or in consequence of a settlement to which this Chapter applies, is so dealt with that it, or assets representing it, will or may become payable or applicable to or for the benefit of a child of the settlor in the future (whether on fulfilment of a condition, or the happening of a contingency, or as the result of the exercise of a power or discretion conferred on any person, or otherwise) shall be deemed to be paid to or for the benefit of that child; and
(b) any income so dealt with which is not required by the settlement to be allocated, at the time when it is so dealt with, to any particular child or children of the settlor shall be deemed to be paid in equal shares to or for the benefit of each of the children to or for the benefit of whom or any of whom the income or assets representing it will or may become payable or applicable.
(2) Where any income is dealt with as mentioned in subsection (1) above by virtue or in consequence of a settlement to which this Chapter applies, being a settlement which, at the time when the income is so dealt with, is an irrevocable settlement—
(a) subsection (1) above shall not apply to that income unless and except to the extent that that income consists of, or represents directly or indirectly, sums paid by the settlor which are allowable as deductions in computing his total income; and
(b) subject to subsection (3) below, any sum whatsoever paid thereafter by virtue or in consequence of the settlement, or any enactment relating thereto, to or for the benefit of a child of the settlor, being a child who at the time of the payment is unmarried and below the age of 18, shall be deemed for the purposes of section 663 to be paid as income.
(3) Subsection (2)(b) above shall not apply if and to the extent that the sum paid as mentioned in that paragraph together with any other sums previously so paid (whether to that child or to any other child who, at the time of the payment, was unmarried and below the age of 18) exceeds the aggregate amount of the income which, by virtue or in consequence of the settlement, has been paid to or for the benefit of a child of the settlor, or dealt with as mentioned in subsection (1) above, since the date when the settlement took effect or the date when it became irrevocable, whichever is the later.
(1) For the purposes of this Chapter, a settlement shall not be deemed to be irrevocable if its terms provide—
(a) for the payment to the settlor or, during the life of the settlor, to the wife or husband of the settlor for his or her benefit, or for the application for the benefit of the settlor or, during the life of the settlor, of the wife or husband of the settlor, of any income or assets in any circumstances whatsoever during the life of the settlor’s child; or
(b) for the determination of the settlement by the act or on the default of any person; or
(c) for the payment of any penalty by the settlor in the event of his failing to comply with the provisions of the settlement.
In this section “the settlor’s child”, in relation to any settlement, means any child of the settlor to or for the benefit of whom any income, or assets representing it, is or are or may be payable or applicable by virtue or in consequence of the settlement.
(2) For the purposes of this Chapter, a settlement shall not be deemed to be revocable by reason only—
(a) that it contains a provision under which any income or assets will or may become payable to or applicable for the benefit of the settlor, or the wife or husband of the settlor, on the bankruptcy of the settlor’s child or in the event of an assignment of or charge on that income or those assets being executed by the settlor’s child; or
(b) that it provides for the determination of the settlement by the act or on the default of any person in such a manner that the determination will not, during the lifetime of the settlor’s child, benefit the settlor or the wife or husband of the settlor; or
(c) in the case of a settlement to which section 33 of the [1925 c. 19.] Trustee Act 1925 applies, that it directs income to be held for the benefit of the settlor’s child on protective trusts, unless the trust period is a period less than the life of the child or the settlement specifies some event on the happening of which the child would, if the income were payable during the trust period to him absolutely during that period, be deprived of the right to receive all or part of the income.
(1) Where interest is paid by the trustees of a settlement to which this Chapter applies there shall be deemed for the purposes of this Chapter to be paid to or for the benefit of a child of the settlor who at the time of the payment is unmarried and below the age of 18 (in addition to any other amount deemed to be so paid) an amount equal to a fraction—
of the interest, where—
A is the whole of the income arising under the settlement in the year of assessment, less any expenses of the trustees of the settlement paid in that year which, in the absence of any express provision of the settlement, would be properly chargeable to income, and
B is such part of A as is paid to or for the benefit of any child of the settlor who is unmarried and below the age of 18.
(2) This section shall not apply to interest in respect of which relief from tax is allowable under any provision of the Income Tax Acts or to interest payable to the settlor or the wife or husband of the settlor (if living with the settlor).
(3) Nothing in this section shall be construed as affecting the liability to tax of the person receiving or entitled to the interest.
(4) For the purpose of this section “income arising under the settlement” has the meaning given by section 681, which for that purpose shall be deemed to apply in relation to settlements to which this Chapter applies as it applies in relation to settlements to which Chapter III of this Part applies.
(5) In this section the reference to the trustees' expenses excludes sums mentioned in section 682(1)(a).
(1) Where, by virtue of this Chapter, any income tax becomes chargeable on and is paid by the person by whom a settlement was made or entered into, that person shall be entitled—
(a) to recover from any trustee or other person to whom the income is payable by virtue or in consequence of the settlement the amount of the tax so paid; and
(b) for that purpose to require an inspector to furnish to him a certificate specifying the amount of income in respect of which he has so paid tax and the amount of the tax so paid,
and any certificate so furnished shall be conclusive evidence of the facts appearing thereby.
(2) Where any person obtains in respect of any allowance or relief a repayment of income tax in excess of the amount of the repayment to which he would but for the provisions of this Chapter have been entitled, an amount equal to the excess shall be paid by him to the trustee or other person to whom the income is payable by virtue or in consequence of the settlement, or, where there are two or more such persons, shall be apportioned among those persons as the case may require.
If any question arises as to the amount of any payment or as to any apportionment to be made under this subsection, that question shall be decided by the General Commissioners whose decision thereon shall be final.
(3) Subject to section 833(3), any income which is deemed by virtue of this Chapter to be the income of any person shall be deemed to be the highest part of his income.
(1) In the case of any settlement where there is more than one settlor, this Chapter shall, subject to the provisions of this section, have effect in relation to each settlor as if he were the only settlor.
(2) In the case of any such settlement, only the following can, for the purposes of this Chapter, be taken into account, in relation to any settlor, as income paid by virtue or in consequence of the settlement to or for the benefit of a child of the settlor, that is to say—
(a) income originating from that settlor; and
(b) in a case in which section 664(2)(b) applies, any sums which are under that paragraph to be deemed to be paid as income.
(3) In applying section 664(2)(b) to any settlor—
(a) the references to sums paid by virtue or in consequence of the settlement or any enactment relating thereto include only sums paid out of property originating from that settlor or income originating from that settlor; and
(b) the reference to income which by virtue or in consequence of the settlement has been paid to or for the benefit of a child of the settlor or dealt with as mentioned in section 664(1) includes only income originating from that settlor.
(4) References in this section to property originating from a settlor are references to—
(a) property which that settlor has provided directly or indirectly for the purposes of the settlement; and
(b) property representing that property; and
(c) so much of any property which represents both property provided as mentioned in paragraph (a) above and other property as, on a just apportionment, represents the property so provided.
(5) References in this section to income originating from a settlor are references to—
(a) income from property originating from that settlor; and
(b) income provided directly or indirectly by that settlor.
(6) In subsections (4) and (5) above—
(a) references to property or income which a settlor has provided directly or indirectly include references to property or income which has been provided directly or indirectly by another person in pursuance of reciprocal arrangements with that settlor but do not include references to property or income which that settlor has provided directly or indirectly in pursuance of reciprocal arrangements with another person; and
(b) references to property which represents other property include references to property which represents accumulated income from that other property.
An inspector may by notice require any party to a settlement to furnish him within such time as he may direct (not being less than 28 days) with such particulars as he thinks necessary for the purposes of this Chapter.
In this Chapter—
“child” includes a stepchild and an illegitimate child;
“settlement” includes any disposition, trust, covenant, agreement, arrangement or transfer of assets;
“settlor”, in relation to a settlement, includes any person by whom the settlement was made or entered into directly or indirectly, and in particular (but without prejudice to the generality of the preceding words of this definition) includes any person who has provided or undertaken to provide funds directly or indirectly for the purpose of the settlement, or has made with any other person a reciprocal arrangement for that other person to make or enter into the settlement;
“income”, except in the phrase (occurring in section 663(1)) “be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year and not as the income of any other person”, includes any income chargeable to income tax by deduction or otherwise and any income which would have been so chargeable if it had been received in the United Kingdom by a person resident and ordinarily resident in the United Kingdom.
(1) If and so long as the terms of any settlement (wherever made) are such that—
(a) any person has or may have power, whether immediately or in the future, and whether with or without the consent of any other person, to revoke or otherwise determine the settlement or any provision thereof and, in the event of the exercise of the power, the settlor or the wife or husband of the settlor will or may cease to be liable to make any annual payments payable by virtue or in consequence of any provision of the settlement; or
(b) the settlor or the wife or husband of the settlor may, whether immediately or in the future, cease, on the payment of a penalty, to be liable to make any annual payments payable by virtue or in consequence of any provision of the settlement,
any sums payable by the settlor or the wife or husband of the settlor by virtue or in consequence of that provision of the settlement in any year of assessment shall be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year and not as the income of any other person.
(2) Where any such power as is referred to in subsection (1)(a) above cannot be exercised—
(a) in the case of a covenanted payment to charity (as defined by section 660(3)), within the period of three years, or
(b) in any other case, within the period of six years,
from the time when the first of the annual payments so referred to becomes payable, and the like annual payments are payable in each year throughout that period, subsection (1)(a) above shall not apply so long as that power cannot be exercised.
(3) In subsections (1) and (2) above—
(a) the references to a power to revoke or otherwise determine a settlement or any provision thereof shall be deemed to include references to any power to diminish the amount of any payments which are or may be payable under the settlement or any provision thereof and to any power to diminish the amount of any annual payments which the settlor or the wife or husband of the settlor is or may be liable to make by virtue or in consequence of any provision of the settlement;
(b) the references to the settlor or the wife or husband of the settlor ceasing to be liable to make any annual payments payable by virtue or in consequence of any provision of the settlement shall be deemed to include references to a diminution of the amount of any such annual payments which the settlor or the wife or husband of the settlor is or may be liable to make;
but the sums to be treated under subsections (1) and (2) above as the income of the settlor for any year of assessment and not as the income of any other person shall, where those subsections would not apply but for paragraph (b) above, be such part only of the sums payable as mentioned in that paragraph by the settlor or the wife or husband of the settlor in that year as corresponds to the diminution mentioned in that paragraph.
(1) If and so long as the terms of any settlement (wherever made) are such that—
(a) any person has or may have power, whether immediately or in the future, and whether with or without the consent of any other person, to revoke or otherwise determine the settlement or any provision thereof; and
(b) in the event of the exercise of the power, the settlor or the wife or husband of the settlor will or may become beneficially entitled to the whole or any part of the property then comprised in the settlement or of the income arising from the whole or any part of the property so comprised,
any income arising under the settlement from the property comprised in the settlement in any year of assessment or from a corresponding part of that property, or a corresponding part of any such income, as the case may be, shall, subject to subsection (2) below, be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year and not as the income of any other person.
(2) Where any such power cannot be exercised within six years from the time when any particular property first becomes comprised in the settlement, subsection (1) above shall not apply to income arising under the settlement from that property, or from property representing that property, so long as the power cannot be exercised.
(3) In subsection (1) above the references to a power to revoke or otherwise determine a settlement or any provision thereof shall be deemed to include references to—
(a) any power to diminish the property comprised in the settlement; and
(b) any power to diminish the amount of any payments which are or may be payable under the settlement or any provision thereof to any person other than the settlor and the wife or husband of the settlor.
(1) If and so long as the settlor has an interest in any income arising under or property comprised in a settlement (wherever made), any income so arising during the life of the settlor in any year of assessment shall, to the extent to which it is not distributed, be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year and not as the income of any other person except that—
(a) if and so long as that interest is an interest neither in the whole of the income arising under the settlement nor in the whole of the property comprised in the settlement, the amount of income to be treated as the income of the settlor by virtue of this subsection shall be such part of the income which, but for this paragraph, would be so treated as is proportionate to the extent of that interest; and
(b) where it is shown that any amount of the income which is not distributed in any year of assessment consists of income which falls to be treated as the income of the settlor for that year by virtue of section 671 or 672, that amount shall be deducted from the amount of income which, but for this paragraph, would be treated as his for that year by virtue of this subsection.
(2) Subject to subsection (3) below, the settlor shall, for the purpose of subsection (1) above, be deemed to have an interest in income arising under or property comprised in a settlement if any income or property which may at any time arise under or be comprised in that settlement is, or will or may become, payable to or applicable for the benefit of the settlor or the wife or husband of the settlor in any circumstances whatsoever.
(3) The settlor shall not be deemed to have an interest in any income arising under or property comprised in a settlement—
(a) if and so long as that income or property cannot become payable or applicable as mentioned in subsection (2) above except in the event of—
(i) the bankruptcy of some person who is or may become beneficially entitled to that income or property; or
(ii) any assignment of or charge on that income or property being made or given by some such person; or
(iii) in the case of a marriage settlement, the death of both the parties to the marriage and of all or any of the children of the marriage; or
(iv) the death under the age of 25 or some lower age of some person who would be beneficially entitled to that income or property on attaining that age; or
(b) if and so long as some person is alive and under the age of 25 during whose life that income or property cannot become payable or applicable as mentioned in subsection (2) above except in the event of that person becoming bankrupt or assigning or charging his interest in that income or property.
(1) This section applies to any settlement (wherever made) if and so long as the terms of the settlement are such that any person has or may have power, exercisable at his discretion, whether immediately or in the future, and whether with or without the consent of any person—
(a) to pay or apply to or for the benefit of the settlor or the wife or husband of the settlor the whole or any part of the income or property which may at any time arise under or be comprised in the settlement; or
(b) to secure the payment or application to or for the benefit of the settlor or the wife or husband of the settlor of the whole or any part of that income or property.
(2) Subject to subsections (3) and (4) below, any income arising in any year of assessment under a settlement to which this section applies or, as the case may be, any income so arising from the property comprised in any such settlement or from a corresponding part of that property, or a corresponding part of any such income, shall (so far as it is not so treated apart from this section) be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year and not as the income of any other person.
(3) Where the power mentioned in subsection (1) of this section cannot be exercised within six years from the time when any income or class of income first arises under the settlement or from the time when any particular property first becomes comprised in the settlement, then, so long as the power cannot be exercised, subsection (2) above shall not apply to any income arising under the settlement or, as the case may be, any income of that class or income from that property or property representing that property.
(4) Where, under section 673(3), the settlor is not deemed to have an interest in any income arising under or property comprised in the settlement, subsection (2) above shall not apply to that income or, as the case may be, to income arising from that property.
(1) Tax chargeable by virtue of section 671, 672, 673 or 674 shall be charged under Case VI of Schedule D.
(2) In computing the liability to income tax of a settlor chargeable by virtue of any of those sections the same deductions and reliefs shall be allowed as would have been allowed if the income treated as his by virtue of that section had been received by him.
(3) Where, by virtue of any of those sections, any income tax becomes chargeable on and is paid by a settlor, he shall be entitled—
(a) to recover from any trustee, or other person to whom income arises under the settlement, the amount of the tax so paid; and
(b) for that purpose to require an inspector to furnish to him a certificate specifying the amount of income in respect of which he has so paid tax and the amount of tax so paid.
Any certificate so furnished shall be conclusive evidence of the facts stated therein.
(4) Where any person obtains, in respect of any allowance or relief, a repayment of income tax in excess of the amount of the repayment to which he would, but for section 671, 672, 673 or 674, have been entitled, an amount equal to the excess shall be paid by him to the trustee or other person to whom income arises under the settlement, or, where there are two or more such persons, shall be apportioned among those persons as the case may require.
If any question arises as to the amount of any payment or as to any apportionment to be made under this subsection, that question shall be decided by the General Commissioners whose decision thereon shall be final.
(5) Subject to section 833(3), any income which is treated by virtue of section 671, 672, 673 or 674 as income of a settlor shall be deemed for the purpose of this section to be the highest part of his income.
(1) Where, by virtue or in consequence of any settlement to which this section applies, the settlor pays directly or indirectly in any year of assessment to the trustees of the settlement any sums which would, but for this subsection, be allowable as deductions in computing his total income for that year, those sums shall not be so allowable to the extent to which the aggregate amount thereof falls within the amount of income arising under the settlement in that year which has not been distributed, less—
(a) so much of any income arising under the settlement in that year which has not been distributed as is shown to consist of income which has been treated as the income of the settlor by virtue of section 671, 672 or 674, and
(b) the amount of income so arising in that year which is treated as the income of the settlor by virtue of section 673.
(2) For the purposes of subsection (1) above, any sum paid in any year of assessment by the settlor to any body corporate connected with the settlement in that year shall be treated as if it had been paid to the trustees of the settlement in that year by virtue or in consequence of the settlement.
(3) No relief shall be given under any of the provisions of the Income Tax Acts on account of tax paid in respect of so much of any income arising under a settlement in any year of assessment as is equal to the aggregate amount of any sums paid by the settlor in that year which are not allowable as deductions by virtue of this section.
(4) This section shall apply to any settlement (wherever made) made after 26th April 1938, and where income arising under any settlement (wherever made) made on or before that date is treated as the income of the settlor by virtue of section 671 or 672 but ceases to be so treated by reason of any variation of the terms of the settlement made after that date, or would have been so treated but for such a variation, this section shall apply to that settlement as from the date when the variation takes effect.
(5) In this section, references to sums paid by a settlor include references to sums paid by the wife or husband of the settlor.
(1) Any capital sum paid directly or indirectly in any year of assessment by the trustees of a settlement to which this section applies to the settlor shall—
(a) to the extent to which the amount of that sum falls within the amount of income available up to the end of that year, be treated for all the purposes of the Income Tax Acts as the income of the settlor for that year;
(b) to the extent to which the amount of that sum is not by virtue of this subsection treated as his income for that year and falls within the amount of the income available up to the end of the next following year, be treated for those purposes as the income of the settlor for the next following year;
and so on for each subsequent year up to a maximum of ten subsequent years, taking the reference in paragraph (b) to the year mentioned in paragraph (a) as a reference to that and any other year before the subsequent year in question.
(2) For the purposes of subsection (1) above, the amount of income available up to the end of any year shall, in relation to any capital sum paid as mentioned in that subsection, be taken to be the aggregate amount of income arising under the settlement in that year and any previous year which has not been distributed, less—
(a) the amount of that income taken into account under that subsection in relation to that sum in any previous year or years; and
(b) the amount of any other capital sums paid to the settlor in any year before that sum was paid; and
(c) so much of any income arising under the settlement in that year and any previous year which has not been distributed as is shown to consist of income which has been treated as income of the settlor by virtue of section 671, 672, 674 or 683; and
(d) any income arising under the settlement in that year and any previous year which has been treated as the income of the settlor by virtue of section 673; and
(e) any sums paid by virtue or in consequence of the settlement, to the extent that they are not allowable, by virtue of section 676, as deductions in computing the settlor’s income for that year or any previous year; and
(f) any sums paid by virtue or in consequence of the settlement in that year or any previous year which have been treated as the income of the settlor by virtue of section 664(2)(b); and
(g) any sums included in the income arising under the settlement as amounts which have been or could have been apportioned to a beneficiary as mentioned in section 681(1)(b); and
(h) an amount equal to the sum of tax at the basic rate and tax at the additional rate on—
(i) the aggregate amount of income arising under the settlement in that year and any previous year which has not been distributed, less
(ii) the aggregate amount of the income and sums referred to in paragraphs (c), (d), (e), (f) and (g) above.
(3) Where any amount is included in a person’s income by virtue of section 421 in respect of any loan or advance, there shall be a corresponding reduction in the amount (if any) afterwards falling to be so included in respect of it by virtue of this section.
(4) Where the capital sum paid to the settlor is a sum paid by way of loan, then—
(a) if the whole of it is repaid, no part of that sum shall by virtue of subsection (1) above be treated as the settlor’s income for any year of assessment after that in which the repayment occurs; and
(b) if one or more capital sums have previously been paid to him by way of loan and wholly repaid, the amount of that capital sum shall be treated as equal to its excess, if any, over so much of the sum or sums previously paid as has already fallen to be treated as his income by virtue of that subsection.
(5) Where the capital sum paid to the settlor is a sum paid by way of complete repayment of a loan, then, if an amount not less than that sum is thereafter lent by the settlor to the trustees of the settlement, no part of that sum shall by virtue of subsection (1) above be treated as his income for any year of assessment after that in which the further loan is made.
(6) Where the whole or any part of any sum is treated by virtue of this section as income of the settlor for any year, it shall be treated as income of such an amount as, after deduction of both tax at the basic rate and tax at the additional rate for that year, would be equal to that sum or that part of that sum.
(7) Tax chargeable by virtue of this section shall be charged under Case VI of Schedule D; and there shall be set off against the tax charged on any amount treated by virtue of this section as income of the settlor for any year an amount equal to—
(a) the sum of tax at the basic rate and tax at the additional rate for that year on the amount so treated as his income; or
(b) so much of that sum as is equal to the tax charged,
whichever is the less.
