The paper presents the method used by the Ministry of Finance for forecasting central budget revenue. The procedure for drawing up central budget revenue forecasts has not up to now been published as a formal set of equations. The presented set of equations reflects the practice used for forecasting central budget revenue. Formalising the process of developing central budget revenue forecasts is even more valuable as it enables both the identification of the dependencies between taxes and macroeconomic factors which are built into the forecasting process, as well as those dependencies (e.g. a lack of feedback between taxes and the overall price level), which are not taken into account in the drawing up phase of the forecast. Due to the amount of space available the text regarding the issue of public finance has been limited.
