  The aim of this paper is to calculate the optimal rate of value added tax with emphasis on harmful products and waste and oil revenues using a model of endogenous growth for Iran’s economy. For this purpose, at first, a generalized growth model for three parts including households, firms and government developed. After developing the model and achieving a determiner relationship of the optimal rate of value added tax, using the parameters of Iran’s economy, the model was calibrated and tax optimized values ​​for different scenarios were calculated. The results showed that in the face of declining oil revenues, to remain in a constant situation, optimal rate of value added tax will be increased. More economic growth will increase the tax optimal rate. By increasing social sensitivity to the harmful products and waste, in order to provide optimum conditions for social welfare, the optimal rate of value added tax should be increased.   Manuscript profile
