Many so-called auxiliary companies exist in Switzerland. These are corporations, cooperative societies and foundations that only carry out a supplementary business activity in Switzerland. Their main sources of trade are, indeed, foreign-oriented.
Unlike some companies, auxiliary companies have a special tax status. As far as their tax regime is concerned, they enjoy a reduction of the net income tax of the foreign source. As for contributions on income from Swiss sources, they are the same as for other companies and the rate remains normal.
It should be noted that this tax status only applies to cantonal and municipal taxes. As a result, companies must claim their taxes from the cantonal tax authorities. Moreover, it becomes null and void after 5 years, provided it is renewed. However, this renewal requires several requirements.
