Corporation Tax is a tax on the taxable profits of limited companies and other organisations including clubs, societies, associations and other unincorporated bodies for each accounting period. For Corporation Tax, the tax year is called the ‘financial year’ or ‘fiscal year’ and runs from 1 April to 31 March. A company must file a return, using form CT600, and assess its liability to tax, normally within 12 months of the end of its accounting year. Corporation tax is a major part of your trading costs.
