The very important instrument of public policy is a public budgets system, which is one of the most significant parts of the budgetary scale. Public budget performs an allocation, redistribution and stabilization function and as an account balance it balances ordinary and capital incomes and outlays. Public budget consists of state budget and municipal authorities budget. Nowadays most of European public budgets are deficient. Fiscal deficit is a result of a short-term imbalance. In the Czech Republic the public budgets have been deficient since 1996, when the balance of public incomes and outlays was -11,5 milliard CZK. After the admission of the Czech Republic to the European Union the public deficit within convergence criteria has been still declining under the norm of 3 % GDP. In order to public budgets deficit reducing the public finances reform is in progress in the Czech Republic. Its integral part is a fiscal reform with objective to transfer a tax load from direct taxes to indirect taxes and actively stimulate tax revenues of public budgets.
