Abstract: Abstract This study aims to present a methodology and construct a model for estimating corporate tax revenue, which is one of the main revenues. There is a need for a new tax revenue estimation model to replace both the existing tax revenue elasticity values that have been adopted for estimating tax revenue and the method of directly estimating tax revenue without first analyzing the increase and decrease in the taxable amount. The author focuses on the estimation of corporate tax revenue. To do it, the author focuses on the taxable object, that is, corporate profits, and the corporation that records it (the profit-making corporation). In addition, it hypothesizes the factors that increase or decrease the declared income, which are GDP growth rate, inflation rate, unemployment rate, interest rate, and population, and hypothesizes how the influence of these macro-variables differs in each industry. The author estimates the declared profit for each industry. The author then estimates the corporate tax revenue by multiplying the declared income that the model estimated for each industry by the given tax rates. The result of this two-stage estimation method reveals that the accuracy of the estimation of this model is higher than the estimation values based on the conventional tax revenue elasticity. Furthermore, unlike the conventional tax revenue elasticity method, the author reveals that this model can accurately estimate (approximate) the actual increase in tax revenue in FY2020, when the economic growth was negative.
