The state budget, as the main fiscal instrument of a country contains the revenues and expenditures of that country. These are called public revenues and public expenditures. Public revenues can be divided into two main groups, namely tax revenues, which include all types of taxes (income tax, corporate income tax, value added tax, excise tax, property taxes, customs duties) and non-tax revenues, which include contributions (employment, pension insurance, health insurance), fees or taxes and other non-tax public revenues, which are revenues from property, aid (from international organizations, foreign governments, from the budget), income from own business, fines and donations. One of the most interesting taxes mentioned is the value-added tax. First introduced by France in 1958, it was accepted by all of the developed countries of the world except the United States and Australia. In Croatia, the value-added tax is in use since 1998, and that rate is currently at 25%. The most important division of public expenditures is on ordinary and extraordinary, productive and unproductive, deferrable and urgent, expenditures of central, regional and local authorities, personal and material, financial and natural, and investment and transfer. There are two types of budget. The first is a balanced budget in which revenues equal expenditures. The second is an unbalanced budget. Unbalanced budget may be in the form of deficit when expenditures exceed revenues, and in the form of surplus when revenues exceed expenditures.
