CIRD98400 | R&D tax relief: legislative structure and time line: FA04 changes
From HM Revenue & Customs · Corporate Intangibles Research and Development Manual
New definition of R&D
As mentioned at CIRD98050 the new definition came into force for accounting periods ending on or after 1 April 2004. While it is intended to make the meaning of R&D clearer it is not considered to materially change the definition of R&D; only to express it more simply and in a more structured way.
Changes to consumable stores and introduction of software
FA04/S141 introduced new categories of qualifying expenditure to replace consumable stores. These are expenditure on software (CIRD82500) and consumable items (CIRD82300).
These provisions come into force for expenditure on or after 1 April 2004.
When R&D revenue expenditure can be deducted
FA04/S53 (now CTA09/S1308) introduced a change to the rules for when expenditure can be eligible for the R&D tax relief, the change is given effect for expenditure incurred in accounting periods beginning on or after 1 January 2005 by a statutory instrument (SI2004/3268).
