| Research Abstract |
1.We showed it by a simulation that the effective tax rate of equity income was higher in the current financial income tax system in Japan than that of interest income because capital loss was not offset against interest income.
2.We have to consider it that the statutory tax rate of equity income is also higher than that of interest income because of corporate tax.
3.We showed it theoretically that portfolio of investors was distorted and their welfare was decreased by above 1 and 2 in the current financial income tax system.
4.We propose it that the current tax system should be replaced by a new system which taxes net aggregate financial income by a single rate.
5.The new tax system should be based on dual income tax instead of aggregate income tax.
6.The integration method of corporation tax and individual tax should be inquired even if the current financial income tax system in Japan would be reformed.
