​​​The EU Code of Conduct Group was set up in 1998 to assess whether business tax measures in Member States were harmful using a Code of Conduct as the basis for assessment. The scope of the code included business tax measures in the dependent and associated territories of Member States.

In 1999 the Code Group began its assessment of tax measures including those for Jersey. The result of this assessment was that some of Jersey's then existing tax measures were found to be harmful under the Code. Jersey replaced these measures with the present 0/10 corporate tax regime. In 2003 this was accepted by the Code Group as being code compliant but at that time the regime did not include an element of shareholder taxation which the Code Group has now considered.

The Code of Conduct Group at its meeting in November 2010 decided that the 0/10 regime in its present form gave rise to harmful effects to which decision Jersey will respond in due course.

The following documents include a detailed background report on 0/10 and a statement from the Chief Minister, Senator Terry Le Sueur.
