Investigating the Impact of Tax Revenues on Macroeconomic Variables

Although taxes have always been a major source of funding for governments and an effective tool for the government to achieve its goals, these important tools have led to disruptions in the economy and have led to widespread differences among economists. It has been about the role and size of government in the economy. The purpose of this paper was to investigate the Impact of tax revenues on macroeconomic variables. The model parameters are estimated using seasonal adjusted time series data for the period 2009-2010. To estimate the bizarre parameters of the model, the previous standard distribution, mean, and deviation of the parameters must first be determined. The parameters are calculated. The results of the model estimation showed that the revenues from VAT have a positive and significant effect on the economic growth of different provinces. Also, the amount of intermittent growth rate of GDP per capita in the provinces has a positive and significant effect on the economic growth rate of this year and also the variable of bank credit, investment rate, has a positive and significant effect on economic growth rate. Also, the variable of investment and government spending has a positive and significant effect, but the inflation rate has a significant and negative effect on economic growth. The results also showed that a short-term tax shock has a negative impact on economic growth and consumption, but in the long run, with an increase in tax revenues, GDP growth and, consequently, consumption and investment in the economy have increased.
