Background

The way in which company losses can be utilised depends on the type of loss, the period in which it arises and the type of profits against which it may be relieved. Whilst on some occasions there may only be one option available for companies using losses, there are often multiple options available and careful planning is required to ensure that losses are used in the most tax-efficient way possible.

This guidance note provides an overview of the rules relating to different types of company losses and includes links to more detailed information. A summary of corporation tax losses and the ways in which they can be used is set out in Loss matrix ― corporation tax losses.

Further information can also be found in the HMRC company losses toolkit which includes a checklist and commentary on the mitigation of risks associated with the use of company losses.
