EM4816 - Penalties: Incorrect Returns, Accounts etc: Company Losses Carried Back
This guidance applies to returns with a filing date on or before 31 March 2009.
Guidance for returns and other documents with a filing date on or after 1 April 2009, where the return relates to a tax period beginning on or after 1 April 2008, is contained in CH80000+.
Where a culpable tax difference has been established for an earlier year and that year is affected by a loss relating to a later year claimed to be carried back, the loss should be regarded as primarily allocated against any non-culpable tax.
