The concept of residence is important because corporation tax is chargeable on the worldwide profits of any company that is resident in the UK.CTA 2009, s 5
This guidance note outlines when a company will be treated as resident in the UK. There may also be tax consequences when the residence of a company changes.
See the Inbound migration guidance note and the Outbound migration guidance note.
A company will be treated as resident in the UK if it is incorporated in the United Kingdom (the 'statutory test' - CTA 2009, s 14) or centrally managed and controlled in the UK (the 'case law test'). See also the Non-UK companies subject to UK tax guidance note for further commentary on how a non-UK company may be subject to UK tax and the relevant UK filing requirements.
