The purpose of this article is to study the impact of fiscal policy on economic growth in Bulgaria for the period 1995–2018. The descriptive analysis is focused on the general trends in fiscal policy and tax structure. The influence of government spending and taxation on economic growth is studied through regressions on time-series data. The empirical estimates prove that taxation is a more reliable instrument of fiscal policy than government spending in terms of a small open emerging-market economy. The dilution of the effect of public spending is probably caused by the high negative values of the current account balance that have been maintained for long periods. Thus, when domestic supply is weak, government expenditure cannot stimulate domestic production, as supply is dominated by import goods. Public investments demonstrate a negative effect on economic growth, which suggests a low productivity of investment spending. A factor of great importance is the level of corruption, which is strongly correlated with government investments, but is harmful to their efficiency. The Bulgarian tax system demonstrates consistency with economic growth. The receipts from value-added tax seems growth-conductive. The decrease of the corporate income tax rate exerts a positive impact on economc performance during the analyzed period, while personal income taxation demonstrates a negative effect. Property taxation has no significant relation with the growth of the Bulgarian economy.
