Abstract
The article focuses on a remuneration, which serves as a base for a tax. The key question is whether another tax, one that is a part of the remuneration itself, should be included in the base of the aforementioned tax and if so, under what conditions.
In the article, the term remuneration is analysed as a phenomenon of private as well as public law. Furthermore, the constitutionality of intranational double taxation is discussed and the conclusions are applied to the key question of inclusion of different taxes in the tax base.
