Section 18 of, and Schedule 2 to, the Finance Act 2021 (ch. 26, “FA21”) provide for a temporary extension to the carry back of trading losses from one year to three years, for losses up to £2,000,000 per 12-month period for companies and groups of companies. This has effect for companies with accounting periods ending between 1 April 2020 and 31 March 2022. A company may not make a claim that exceeds £200,000 unless the total of all other claims made by the company, and any other members of the group of which the company is part, does not exceed £2,000,000. In order to apply this £2,000,000 cap, FA21 requires groups to specify on a loss carry-back allocation statement how the losses are to be applied. These Regulations provide for the requirements for the submission of loss carry-back allocation statements.
