Corporation tax

(see also corporate tax)

Corporation tax is a tax levied in the United Kingdom on the profits made by companies and on the profits of permanent establishments of non-UK resident companies and associations that trade in the EU.

Prior to the tax's enactment on 1 April 1965, companies and individuals paid the same income tax, with an additional profits tax levied on companies.

The UK government has faced problems with its corporate tax structure, including European Court of Justice judgements that aspects of it are incompatible with European Union treaties. Tax avoidance schemes marketed by the financial sector have also proved an irritant, and been countered by complicated anti-avoidance legislation.

The complexity of the corporation tax system is a recognised issue. The Labour government, supported by the other parties, has expressed its commitment to wide-scale reform.
