(2) Subject to section 201, income tax shall be charged under Schedule E in respect of any payment to which this section applies made to the holder or past holder of any office or employment, or to his or her executors or administrators, whether made by the person under whom he or she holds or held the office or employment or by any other person.
(3) For the purposes of this section and section 201, any payment made to the [spouse, civil partner, or any relative or dependant]1 of a person who holds or has held an office or employment, or made on behalf of or to the order of that person, shall be treated as made to that person, and any valuable consideration other than money shall be treated as a payment of money equal to the value of that consideration at the date when it is given.
(4) Any payment chargeable to tax by virtue of this section shall be treated as income received on the following date-
(a) in the case of a payment in commutation of annual or other periodical payments, the date on which the commutation is effected, and
