5(1)Section 806B (determination of the amounts that are eligible unrelieved foreign tax) is amended as follows.
(2)For subsections (3) to (6) (amounts of eligible unrelieved foreign tax in Case B) substitute—
“(3)In Case B, the amount (if any) by which—
(a)the aggregate of the upper rate amounts falling to be brought into account for the purposes of this paragraph by virtue of subsection (4) or (5) below, exceeds
(b)the amount of tax to be taken into account as mentioned in section 799(1) in the case of the Case V dividend, before any increase under section 801(4B),
shall be an amount of eligible unrelieved foreign tax.
(4)In the case of the Case V dividend (but not any lower level dividend), the upper rate amount to be brought into account for the purposes of subsection (3)(a) above—
(a)in a case where the mixer cap does not restrict the amount of tax to be taken into account as mentioned in section 799(1) (before any increase under section 801(4B)) in the case of that dividend, is that amount of tax; or
(b)in a case where the mixer cap restricts the amount of tax to be so taken into account in the case of that dividend, is the greater amount that would have been so taken into account if, in the application of the formula in section 799(1A) in the case of that dividend (but not any lower level dividend) M% had, in relation to—
(i)so much of D as does not represent any lower level dividend, and
(ii)so much of U as is not underlying tax attributable to any lower level dividend,
been the upper percentage.
(5)In the case of any dividend (the “relevant dividend”) received as mentioned in subsection (2) or (3) of section 801 which is a lower level dividend in relation to the Case V dividend, the upper rate amount to be brought into account for the purposes of subsection (3)(a) above—
(a)in a case where the mixer cap does not restrict the amount of underlying tax that is treated as mentioned in subsection (2) or (3), as the case may be, of section 801 in the case of the relevant dividend, is the appropriate portion of that amount of underlying tax;
(b)in a case where—
(i)the relevant dividend was paid by a company resident in the United Kingdom, and
(ii)the mixer cap restricts the amount of underlying tax that is treated as mentioned in subsection (2) or (3), as the case may be, of section 801 in the case of that dividend,
is the appropriate portion of that restricted amount of underlying tax; or
(c)in a case where—
(i)the relevant dividend was paid by a company resident outside the United Kingdom, and
(ii)the mixer cap restricts the amount of underlying tax that is treated as mentioned in subsection (2) or (3), as the case may be, of section 801 in the case of that dividend,
is the appropriate portion of the greater amount of tax that would have been so treated if, in the application of the formula in section 799(1A) in the case of that dividend (but not any other dividend) M% had, in relation to so much of D as does not represent any lower level dividend, and so much of U as is not underlying tax attributable to any lower level dividend, been the upper percentage.
(6)For the purposes of subsection (5) above, the “appropriate portion” of any amount there mentioned in the case of a dividend is found by multiplying that amount by the product of the reducing fractions for each of the higher level dividends.”.
(3)In subsection (9) (disregard of sections 806C and 806D for purpose of determining certain amounts in subsections (2)(b), (3)(b) or (5)(b)) for “(3)(b) or (5)(b)” substitute “ (4)(b) or (5)(c) ”.
(4)The amendments made by this paragraph have effect in relation to—
(a)dividends arising on or after 31st March 2001 to companies resident in the United Kingdom from companies resident outside the United Kingdom, and
(b)foreign tax in respect of such dividends,
(whenever any such dividend as is mentioned in section 801(2) or (3) of the Taxes Act 1988 was paid).
