This Practice Note sets out the key features of the corporation tax regime for intangible fixed assets, including relief for expenditure upon, and taxation of receipts from, trading and non-trading intangible fixed assets. Intangible fixed assets are taxed and relieved as income, and relief may be given as expenditure is incurred, on an accounting basis or at a fixed annual rate. This Practice Note was produced in partnership with Anne Fairpo, barrister.
