In the absence of any provision to the contrary (some of which are considered below), the normal rule is that a claim must be made within four years of the end of the accounting period to which it relates (six years prior to 1 April 2010) (FA 1998, Sch. 18, para. 55).
In certain cases, HMRC may permit an extension of the strict time limit in relation to certain elections and claims.
