This work is based on issues of the tax system of the Republic of Croatia. Although there are different types of taxes such as by time of inflow, the purpose of spending, considernig by the bearing of the fiscal burden, according to the method of determining the tax capacity and to the financial autonomy and financial sovereignty, but the most rewiev is placed to the last -mentioned division. According to financial autonomy and financial sovereignty it cultivates each type of taxes, regarding state,council,city (municipality) and common taxes. Analyzing the mentioned types of taxes, it can be said that the most abundant taxes are state taxes, or these one that belongs to the state, while municipal taxes are not so abundant. The main reason is beacuse we are forced to give the part of our income to the state to be able to use public services that are necessary now to live a normal life. The state's most achiving revenue is of the VAT and excise duty, and then from the profit tax, income tax and customs duties. The income of the rest types of taxes such as local and property taxes are extremely small. Considering that the Republic of Croatia is now the part of the EU, its tax system adapts to the guidelines set by the EU.
