Corporation Tax Act 2009 section 10

End of accounting period

Section 10 sets out the events that bring a company's accounting period to an end for corporation tax purposes.

• An accounting period ends on the earliest of several triggering events, including the passage of 12 months, the company's accounting date, or the company starting or ceasing to trade.
• Changes in a company's tax status — such as becoming or ceasing to be UK resident, or moving in or out of the charge to corporation tax — also bring the current accounting period to an end.
• Entering or leaving administration triggers the end of an accounting period, with the period treated as ending immediately before the day the company enters administration.
• These rules do not apply to companies being wound up, which are covered by separate provisions, and they are subject to any other Corporation Tax Acts provision that specifies a different end date.
