Core computational rules: deductible debits: general matters and adjustments for tax purposes: expenditure charged to the profit and loss account as it accrues

CTA09/PART8/S728

General rule

Subject to the exception for previously capitalised expenditure described below, section 728 of Part 8 provides that expenditure on an intangible asset gives rise to a deductible debit for the period of account in which it is written off to a company’s profit and loss account (see CIRD12220).

A deduction is therefore due for any expenditure treated in this way for accounting purposes, which falls within the (wide) definition described in CIRD12250. Examples include expenditure:

  • on maintaining or preserving an asset,
  • on defending title to it,
  • by way of royalties for its use or,
  • for the purpose of acquiring or creating an asset which in the event proves abortive.

Priority of other provisions

But sums written off to the profit and loss account, which represent previously capitalised expenditure, should be excluded from section 728 and relieved instead:

  • under the rules in Chapter 4 of Part 8 if the sums are written off on the realisation of the asset (see CIRD13210 onwards), or otherwise,
  • under CTA09/PART8/S729 (see CIRD12700).

Sums written off on the realisation of intangible assets, which have never appeared on a formal balance sheet simply because the assets turn out to have been sold shortly after acquisition, should be dealt with under Chapter 4.

Tax adjustments

Sums that would otherwise give rise to deductible debits under section 728 are ‘subject to any adjustment required by this Part or Part 4 of TIOPA 2010 (provision not at arm’s length)’. See:

  • CIRD12030 for the meaning of this expression generally,
  • CIRD12580 onwards for the adjustments likely to be in point.
