CIRD20150 | Reinvestment relief: general matters and conditions to be satisfied: form of claim
From HM Revenue & Customs · Corporate Intangibles Research and Development Manual
This paragraph requires a claim to reinvestment relief to specify:
the old assets to which the claim relates,
the expenditure on other assets leading to the deferral in relation to each old asset, and
the amount of relief claimed in relation to that asset.
Otherwise, the general procedural rules for CT claims (Part VII of FA98/SCH18) apply including the four-year time limit in FA98/SCH18/PARA55 (see CTM90610).
See CIRD20015 for the procedure whereby a company may make a provisional declaration of entitlement to relief, similar to that for CG roll-over relief.
