CFC legislation has become an instrument to protect national tax bases and minimize the abusive effects of international tax planning. The Swedish CFC legislation is found in chapter 39a of the ITA whereas it is established under what circumstances CFC taxation can arise. If a shareholder of a foreign legal entity is liable of CFC taxation in Sweden such a holder is also entitled to deduct tax paid by the CFC abroad. The purpose of the granted tax credit is to avoid double taxation, although if foreign tax is paid by another entity than the foreign entity in question such CFC-tax cannot be credited. The situation at hand can result in that the holder is liable of paying double CFC tax, contrary to the purpose of tax credit.

The freedom of establishment is part of the fundamental freedoms concluded in the EC Treaty. The general goal of the Community is to establish an internal market. The freedom of establishment, stated in Article 43 EC stipulates that restrictions on the freedom of establishment on nationals shall be prohibited. However, restrictions on the freedom of establishment can be justified under certain circumstances. The ECJ has developed a rule of reason test which can justify prohibited restrictions if certain criterias are fulfilled. Concerning tax matters the grounds of justification that have been accepted by the ECJ are the cohesion of the tax system, the effectiveness of fiscal supervision, the counteraction of tax avoidance, the need to safeguard the balanced allocation of the power to tax between the Member States and a combination of grounds of justification.

An exemplification scheme serves as a mean to illustrate in what instance double CFC taxation can arise. The scheme concerns a corporate group whereas a Swedish parent company owns a subsidiary in the U.K. through which the parent company plans to establish another subsidiary in the UAE. Swedish tax legislation provides that the Swedish parent company is subject to corporation tax on its worldwide profits in Sweden. However, the parent company is generally not taxed on the profits of its subsidiaries as they arise nor is it taxed on dividends distributed by a subsidiary established in Sweden. Although, when subsidiaries are not resident in Sweden and CFC legislation applies tax exempt according to the intercorporate share holding legislation will not be applicable. Therefore, in order for double CFC taxation to arise it is established that CFC legislation will be applicable to the exemplified scheme. Profits accrued in the UAE will be subject to CFC taxation in both the U.K. and Sweden and double taxation relief will not be granted in Sweden for the CFC tax paid in the U.K. It is questionable if double CFC taxation and the lack of tax relief in such a situation is in compliance with the freedom of establishment.

The analysis, whereas the purpose of this thesis is concluded, follows the reasoning of the ECJ in accordance with the rule of reason. The purpose is to examine if the lack of double CFC tax relief is in compliance with Community law. It is established that since relief is not granted for double CFC taxation, national legislation hinders the freedom of establishment by forcing a parent company to avoid or modify an intra group structure which leads to the unfavorable consequences in taxation. The tax disadvantage must be seen as making it less attractive for Sweden’s own resident to establish in another Member State and the hindering nature of the lack of double CFC taxation relief constitutes a prohibited restriction to the freedom of establishment. The grounds of justification previously accepted by the ECJ are examined in order to establish if such grounds can justify the lack of double CFC tax relief as a prohibited restriction on the freedom of establishment. None of the acknowledged grounds of justification are able to justify the lack of double CFC tax relief and such a restricted measure is therefore not found to be in compliance with Community Law. Lastly, potential adjustments to CFC legislation, regarding the lack of double CFC tax relief, are discussed to enable compliance with Community law.
