(a)any expenditure or sum that may be deducted in calculating the profits or gains of a trade, profession or vocation or property business carried on by the person, or
(b)any expenditure or sum that may be deducted in calculating the emoluments of an employment or office held by the person.

any expenditure or sum in the case of which a deduction of income tax falls or may fall to be made under section 348 or 349(1) of ICTA (annual payments).

5When capital expenditure is incurred
(1)For the purposes of this Act, the general rule is that an amount of capital expenditure is to be treated as incurred as soon as there is an unconditional obligation to pay it.
(2)The general rule applies even if the whole or a part of the expenditure is not required to be paid until a later date.
(3)There are the following exceptions to the general rule.
(4)If under an agreement—
(a)the capital expenditure is expenditure on the provision of an asset,
(b)an unconditional obligation to pay an amount of the expenditure comes into being as a result of the giving of a certificate or any other event,
(c)the giving of the certificate, or other event, occurs within the period of one month after the end of a chargeable period, and
(d)at or before the end of that chargeable period, the asset has become the property of, or is otherwise under the agreement attributed to, the person subject to the unconditional obligation to pay,
the expenditure is to be treated as incurred immediately before the end of that chargeable period.
(5)If under an agreement an amount of capital expenditure is not required to be paid until a date more than 4 months after the unconditional obligation to pay has come into being, the amount is to be treated as incurred on that date.
(6)If under an agreement—
(a)there is an unconditional obligation to pay an amount of capital expenditure on a date earlier than accords with normal commercial usage, and
(b)the sole or main benefit which might have been expected to be obtained thereby is that the amount would be treated, under the general rule, as incurred in an earlier chargeable period,
the amount is to be treated as incurred on the date on or before which it is required to be paid.
(7)This section—
(a)is subject to any provision of this Act which has the effect that expenditure is to be treated as incurred on a date later than would result from the application of this section, and
(b)does not apply to expenditure treated as incurred as a result of a person incurring an additional VAT liability.
6Meaning of “chargeable period”
(1)In this Act “chargeable period” means—
(a)for income tax purposes, a period of account, or
(b)for corporation tax purposes, an accounting period of a company.
(2)“Period of account” means—
(a)in the case of a person entitled to an allowance or liable to a charge in calculating the profits of his trade, profession or vocation, a period for which accounts are drawn up for the purposes of the trade, profession or vocation, and
(b)in the case of any other person entitled to an allowance or liable to a charge, a tax year.
(3)Subsection (2)(a) is subject to subsections (4) to (6).
(4)If—
(a)two periods of account overlap, or
(b)one period of account includes another,
the period common to both is to be treated as part of the first period of account only.
(5)If there is a gap between two periods of account, the gap is to be treated as part of the first period of account.
(6)If a period of account would (apart from this subsection) be longer than 18 months, that period must be treated as divided into separate periods of account—
(a)the first beginning with the start date of the original period, and
(b)each subsequent one beginning with an anniversary of that date,
so as to ensure that none of the periods of account is longer than 12 months.
Chapter 2Exclusion of double relief
7No double allowances
(1)If an allowance is made under any Part of this Act to a person in respect of capital expenditure, no allowance is to be made to him under any other Part in respect of—
(a)that expenditure, or
(b)the provision of any asset to which that expenditure related.
(2)This section does not apply in relation to Parts 7 and 8 (know-how and patent allowances).
8No double relief through pooling under Part 2 (plant and machinery allowances)
(1)Subsection (2) applies if, under Part 2—
(a)any capital expenditure has been allocated to a pool, and
(b)an allowance or charge has been made to or on any person in respect of the pool.
(2)The person to or on whom the allowance or charge has been made is not entitled to an allowance under any Part other than Part 2 in respect of—

(5)This section does not apply in relation to Parts 7 and 8 (know-how and patent allowances).
9Interaction between fixtures claims and other claims
(1)A person is not entitled to make a fixtures claim in respect of any capital expenditure relating to an asset if—
(a)any person entitled to do so has at any previous time claimed an allowance under any Part other than Part 2, and
(b)the claim was for an allowance in respect of capital expenditure relating, in whole or part, to the asset.
(2)Subsection (1) does not prevent a person making a fixtures claim in respect of capital expenditure if—
(a)the only previous claim was under Part 3 or 6 (industrial buildings and research and development allowances), and
(b)section 186(2) or 187(2) (limit on amount of expenditure that may be taken into account) applies to that expenditure.
(3)If a person entitled to do so has made a fixtures claim in respect of capital expenditure relating to an asset, no one is entitled to an allowance on a later claim under any Part other than Part 2 in respect of any capital expenditure relating to the asset.
(4)A person makes a fixtures claim in respect of expenditure if he makes a claim (in the sense given in section 202(3)) under Chapter 14 of Part 2 in respect of the expenditure as expenditure on the provision of a fixture.
10Interpretation
