State budget is the main tool of fiscal policy in every country. It is the most important part of the government, whose primary function is to finance public goods. Taxes are the essential part of state budget incomes and a value-added tax (VAT) makes up most of the revenue from taxes in Slovak republic. Because of this fact, the main goal of the paper is to analyze VAT impact on the state budgets expenditures and incomes in Slovak republic. Since the establishment of the Slovak republic, there were occurred many changes in VAT rates and those changes affected the prices of goods and services. This fact influenced the amount of state budget revenues from VAT. Because of that, the goal of the article is to analyze the development of standard and reduced VAT rates in years 1993 – 2015. The paper quantified the costs related to the management and control of taxation and then evaluated the effectiveness of VAT in relation to the state budget. From the results of the analysis of the revenue to the state budget, we can conclude that despite the gradual increase of tax revenues to the state budget, the share of VAT on tax total revenues, after the increase in the VAT rate by one percentage point, did not increase. In assessing the effectiveness of VAT, we concluded that the expenditures for tax and duties collection are several times lower than the tax revenues to the state budget and collection of tax and duties can be considered as effective.
