Income and Corporation Taxes Act 1988

30 Expenditure on making sea walls

(1) Where in any year of assessment the owner or tenant of any premises incurs any expenditure in the making of any sea wall or other embankment necessary for the preservation or protection of the premises against the encroachment or overflowing of the sea or any tidal river, he shall be treated for the purposes of sections 25, 28 and 31 as making in that year of assessment and in each of the succeeding 20 years of assessment a payment in relation to the premises preserved or protected by the embankment of an amount equal to a twenty-first part of the expenditure and incurred in respect of dilapidation attributable to the year.

(2) Where the whole of that person’s interest in the premises or any part thereof is transferred (whether by operation of law or otherwise) to some other person—

(a) the amount of the payment which he would be so treated as making for the year of assessment in which the transfer takes place shall be treated as being made partly by the transferor and partly by the transferee, as may be just; and

(b) the transferee shall, to the exclusion of the transferor, be treated in any subsequent year—

(i) where the interest transferred is in the whole of the premises, as having made the whole of the payment for that year, and

(ii) where the interest transferred is in part only of the premises, as having made so much of the payment as is properly referable to that part of the premises.

(3) For the purposes of subsection (2) above, where an interest in any premises is a lease and that lease comes to an end, that interest shall be deemed to have been transferred—

(a) if an incoming lessee makes any payment to the outgoing lessee in respect of the embankment in question, to the incoming lessee, and

(b) in any other case, to the owner of the interest in immediate reversion on the lease and, in relation to Scotland, the expression “the owner of the interest in immediate reversion on the lease” shall be construed as a reference to the landlord.

(4) In relation to a company, section 9(1) shall not have effect so as to require references in this section to a year of assessment to be read as references to an accounting period, but any deduction authorised by this section shall be apportioned between the accounting periods (if more than one) comprising the year of assessment, other than any such period ended before the expenditure is incurred, or transfer takes place, by virtue of which the company is entitled to the deduction.

(5) This section shall not apply in relation to any expenditure in respect of which a capital allowance has been made.
