Unless the contrary is stated, references in this article to a claim include references to an election.

A claim for relief, an allowance or repayment must be quantified at the time it is made1 and, subject to any special provision, must be made within four years of the end of the accounting period to which it relates2. For details see A4.204.

A company which has made a claim (whether or not by including it in a return) and subsequently discovers that there was a mistake in it, may amend it by making a supplementary claim within the time limit applicable to the original claim3.

The following claims can only be made by inclusion in a tax return (see also the general provisions described below)4:


    •     group relief, for current year and brought forward losses (see Division D2.2)


    •     capital allowances, including first year tax credits (see Part B3)
