10(1)For the purposes of this Part a lump sum is a winding-up lump sum if—U.K.
(a)the pension scheme is an occupational pension scheme,
(b)the pension scheme is being wound-up,
(c)the member’s employer meets the conditions in sub-paragraph (3),
(d)it is paid when all or part of the member’s lifetime allowance is available,
(e)it extinguishes the member’s entitlement to benefits under the pension scheme, and
(f)it is paid when the member has not reached the age of 75.
(2)But if a lump sum falling within sub-paragraph (1) exceeds 1% of the standard lifetime allowance when the lump sum is paid, the excess is not a winding-up lump sum.
(3)The conditions are that the employer—
(a)has made contributions under the pension scheme in respect of the member,
(b)is not making contributions under any other registered pension scheme in respect of the member, and
(c)undertakes to the Inland Revenue not to make such contributions during the period of one year beginning with the day on which the lump sum is paid.
