D1.1301 Overview of corporation tax self-assessment
For the latest New Development, see ND.1939.
A system of self-assessment applies1 not only to a liability to corporation tax, but also to a liability to tax on the following amounts that are assessable as if they were corporation tax:
• tax on a loan or advance by a close company to a participator (D3.401C)2
• tax on other benefits conferred on a participator (D3.410)3
• the supplementary charge in respect of ring-fence trades (D7.903)4
• tax on the profits of a controlled foreign company (Divisions D4.3, D4.4)5
• the bank levy (Division D7.7)6, and
• the banking surcharge (Division D7.7)7
If a company ceases to be UK resident following the formation of a Societas Europaea (SE) by merger, the corporation tax self-assessment provisions of FA 1998, Sch 18 continue to apply in relation to returns, liabilities, etc before that time as if the company were still UK resident or, if the company has ceased to exist, as if the SE were the company. The same applies if an SE transfers its registered office from the UK and ceases to be UK resident8.
Many of the procedures are similar to those under the income tax self-assessment regime applicable to individuals (see Division E1.2).
