22(1)After section 806J of the Taxes Act 1988 insert—
(1)Sections 806A to 806J shall apply in relation to an amount of eligible unrelieved foreign tax arising in a chargeable period in respect of any of the income of a branch or agency in the United Kingdom of a person resident outside the United Kingdom as they apply in relation to eligible unrelieved foreign tax arising in an accounting period of a company resident in the United Kingdom in respect of any of the company’s income, but with the modifications specified in subsection (2) below.
(2)Those modifications are—
(a)take any reference to an accounting period as a reference to a chargeable period;
(b)take any reference to corporation tax as including a reference to income tax;
(c)take the reference in section 806A(4)(a) to section 797 as a reference to sections 796 and 797;
(d)in relation to income tax, for subsection (2) of section 806B substitute the subsection (2) set out in subsection (3) below.
(3)That subsection is—
“(2)In Case A, the difference between—
(a)the amount of the credit allowed as mentioned in section 806A(4)(b), and
(b)the greater amount of credit that would have been so allowed if, for the purposes of section 796, the amount of income tax borne on the dividend as computed under that section were charged at a rate equal to the upper percentage,
shall be an amount of eligible unrelieved foreign tax.”.”
(2)The amendment made by sub-paragraph (1) has effect in relation to—
(a)dividends arising on or after 31st March 2001, and
(b)foreign tax in respect of such dividends,
(and accordingly the single related dividend or single unrelated dividend which by virtue of that amendment falls to be treated as arising in any chargeable period shall not include any dividend arising on or before 30th March 2001).
