The object of the article is to determine what powers municipalities have in relation to tax revenues and whether municipalities in the Czech Republic have economic autonomy. The first part deals with the general economic autonomy of municipalities, taking into account the European Charter of Local Government. Separate chapters are devoted to the most important of them, namely local taxes and property taxes. The conclusion of the work seeks a comprehensive view of the treatment of individual chapters concerning the autonomy of local authorities, including possible conclusions de lege ferenda.
