The thesis has as purpose to describe and analyse a decision made be the Swedish tax committee in which it was decided that a cooperative economical associations selling price, which was less than the comparable public bonds market price, would be the focus of a withdrawal tax. There are exceptions from a withdrawal tax, that is if the transaction has a business motivation. However the concept, business motivation, is narrowly interpreted both in the preparatory works and in case law, which makes it irrelevant to the situation at hand. A cooperative economical association is a form of association nearest akin to the limited companies. These types of associations have as purpose to increase their owners wealth with the benefit of freedom from personal responsibility. The work concludes that the purpose and meaning of a withdrawal tax is necessary to secure a consistent legality and neutrality between persons conduction business and persons who do not. However, there is one part of the subject matter that seems to be unreasonable. This thesis will show that the market price taken from the public bond market, is not a legal, neutral or comparable price to estimate the full width of a withdrawal tax.
