The Finance Bill 2021 will legislate for a temporary extension of the period over which incorporated and unincorporated businesses may carry-back trading losses.
The current period allowed for carrying back trading losses is one year, which will be extended to three years. This extension will apply to trading losses made by companies in accounting periods ending between 1 April 2020 and 31 March 2022 and to trading losses made by unincorporated businesses in tax years 2020/21 and 2021/22.
For companies, the amount of trading losses that can be carried back to the preceding year remains unlimited. After carry-back to the preceding year, a maximum of £2 million of unused losses will be available for carry-back against profits of the same trade to the earlier 2 years. This £2 million limit applies separately to the unused losses of each 12-month period within the duration of the extension.
This means there will be a cap of £2 million on the extended carry back of losses incurred in accounting periods ending in the period 1 April 2020 to 31 March 2021 and a separate cap of £2 million on the extended carry-back of losses incurred in accounting periods ending in the period 1 April 2021 to 31 March 2022.
A group-level limit will also be put in place, which will require groups including companies that have the capacity to carry back losses in excess of £200,000 to apportion the £2 million cap between the group companies. The Government will publish further details as regards the group limit in due course.
For unincorporated businesses, the amount of trading losses that can be carried back to set against profits of the preceding year remains unlimited. The current restrictions to carry back losses from a trade against general income will remain.
A separate £2 million cap will apply to the extended carry back of losses made in each of the tax years 2020/21 and 2021/22.
This £2 million limit applies separately to the unused losses of each tax year within the duration of the extension.
