Abstarct: The purpose of this study is to investigate the effects of tax and government expenditure shocks as fiscal policy tools on economic growth (gross domestic product) and income distribution in Iran's economy using time series data. In this regard, vector autoregression method has been used. In this research, the impact of direct and indirect taxes shock as well as the effects of government expenditure shock on Iran's economic growth during the period 1370 to 1398 has been investigated. According to the obtained results, the direct tax shock effect on economic growth has been alternately positive and negative and infinite. Therefore, it can be said that the hypothesis that the reaction of real GDP to the shock of increasing direct taxes is negative is rejected. But in the case of indirect taxes, the impact of the indirect tax shock on economic growth has been positive and muted. In short, the impact of government expenditure shock on economic growth has been temporarily negative and muted. Also, the effect of the shock of government budget deficit on economic growth has been insignificant and alternately negative and positive and ultimately muted. Regarding the Gini coefficient, it can be said that the effect of the direct tax shock on the Gini coefficient has been periodic (positive, negative and positive) and ultimately positive and lasting. Also, the effect of the indirect tax shock on the Gini coefficient has been positive and muted, and the effect of the government expenditure shock on the Gini coefficient has been The face has been negative and permanent.
