When capital expenditure is incurred
5
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.

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.

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,
