28Vulnerable person’s liability: VQTI
(1)For the purposes of section 26, VQTI is an amount equal to—
TLV1 - TLV2
where—
TLV2 is an amount determined in accordance with subsection (2) (and subsection (4) where it applies) (total tax liability of vulnerable person), and
TLV1 is an amount determined in accordance with subsection (3) (and subsection (4) where it applies) (what total tax liability of vulnerable person would be if his income included qualifying trusts income).
(2)TLV2 is the total amount of income tax and capital gains tax to which the vulnerable person would be liable for the tax year if his income tax liability were computed in accordance with subsections (5) and (6).
(3)TLV1 is what TLV2 would be if the qualifying trusts income arising (or treated as arising) to the trustees in the tax year in respect of which the trustees are liable to income tax were income of the vulnerable person for the tax year.
(4)Where the vulnerable person is non-UK resident during the tax year—
(a)his income tax liability for the purposes of determining TLV1 and TLV2 is to be computed in accordance with the Income Tax Acts on the assumption that he is resident and domiciled in the United Kingdom throughout the tax year, and
(b)his capital gains tax liability for the purposes of determining TLV1 and TLV2 is to be computed on the assumption that his taxable amount for the purposes of section 3 of TCGA 1992 is equal to his deemed CGT taxable amount.
(5)For the purposes of this section, in a case where income which has arisen to the trustees (whenever it arose) is distributed to the vulnerable person in the tax year, that income is to be disregarded in computing income tax to which he would be liable for the tax year for the purposes of determining TLV1 and TLV2.
(6)For the purposes of this section, in computing income tax to which the vulnerable person would be liable for the tax year for the purposes of determining TLV1 and TLV2, there is to be disregarded any relief which is given by way of a reduction in the amount of income tax to which the vulnerable person would be liable apart from that relief.
(7)For the purposes of this section—
(a)whether or not a vulnerable person is non-UK resident is to be determined in accordance with section 41(2), and
(b)a non-UK resident vulnerable person’s deemed CGT taxable amount is to be determined in accordance with paragraph 3 of Schedule 1.
(8)This section is subject to section 29 (vulnerable person election having effect for only part of tax year).
