807 Sale of securities with or without accrued interest.U.K.
M1(1)In any case where—
(a)a person is treated under section 714(2) as receiving annual profits or gains on the day an interest period ends; and
(b)assuming that, in the chargeable period in which the day falls, he were to become entitled to any interest on the securities concerned, he would be liable in respect of the interest to tax chargeable under Case IV or V of Schedule D; and
(c)he is liable under the law of a territory outside the United Kingdom to tax in respect of interest payable on the securities at the end of the interest period or he would be so liable if he were entitled to that interest,
credit of an amount equal to the relevant proportion of the profits or gains shall be allowed against any United Kingdom income tax or corporation tax computed by reference to the profits or gains, and shall be treated as if it were allowed under section 790(4).
In this subsection the relevant proportion is the rate of tax to which the person is or would be liable as mentioned in paragraph (c) above.
(2)In any case where—
(a)a person is entitled to credit against United Kingdom tax under section 790(4) or any corresponding provision of arrangements under section 788; and
(b)the tax is computed by reference to income consisting of interest which falls due on securities at the end of an interest period and which is treated as reduced by virtue of section 714(5);
then the amount of that credit shall be a proportion of the amount it would be apart from this subsection, and the proportion is to be found by applying the formula—
where—
is the amount of the interest; and
R is the amount by which it is treated as reduced.
(3)M2Where the person entitled to the credit is an individual, subsection (2) above does not apply unless the interest arises from securities to which the person either became or ceased to be entitled during the interest period.
(4)Where section 811(1) applies to any income and, if credit were allowable in respect of it the credit would be reduced by virtue of subsection (2) above, section 811(1) shall have effect in relation to the income as if the reference to any sum paid in respect of tax on it were a reference to the amount which would be the amount of the credit if it were allowable and subsection (2) above applied.
(5)Sections 710 and 711 shall apply for the interpretation of this section.
