Core computational rules: deductible debits: relief for capitalised expenditure on an intangible asset: introduction

CTA09/PART8/S729 - 731


These paragraphs set out how a company may obtain a corporation tax deduction relating to costs incurred on an intangible asset within Part 8 (see CIRD11000 onwards). These are the costs which are capitalised in its accounts in accordance with GAAP (CIRD30000 onwards) and which would normally be of a capital nature on general computational principles. See CIRD12530 onwards for the treatment of costs written off as incurred.

The tax deductions a company obtains for the capitalised cost of an intangible asset are normally based on (and very often the same as) the sums it writes off the asset in its accounts for the period of account in question. But it may instead elect irrevocably instead for relief at a fixed rate of 4% per annum. This fixed rate relief is available regardless of the accounting treatment of the asset.

The starting point for both types of relief is normally the expenditure on the asset capitalised in a company’s accounts. See CIRD12720.

But CIRD12780 describes a limited exception to the approach described above where both of the following conditions apply:

  • a company is regarded as acquiring an asset at market value for the purposes of Part 8
  • the value of the asset in its accounts immediately after its acquisition is nil

See CIRD12755 onwards for detailed guidance on the accounts-based relief and CIRD12905 onwards for fixed rate relief.

If a company recognises expenditure in its accounts on the acquisition of an asset which diverges substantially from the amount recognised for tax (for example in a CG computation) by the other party to the transaction, the reasons should in general be investigated and, if necessary, CT&VAT should be consulted. For the particular case where an intangible asset is acquired as part of a larger bargain see CIRD12730 onwards.
