Corporation Tax: accounting periods: company winding-up

CTA10/CHAPTER5/PART13 (formerly ICTA88/S342)

An accounting period ends and a new one begins when a company starts to be wound up. After that an accounting period ends only at:

  • the expiry of twelve months from its beginning, or
  • the completion of the winding-up.

CTA09/S12 (7), formerly ICTA88/S12 (7), establishes the date when winding-up starts.

CTM36100 onwards gives more general guidance.
