In recent years, the rapid increase in wealth inequality is one of the most
important problems as well as income disparity in Japan. The Gift tax is the
complementary tax of inheritance tax, and these taxes have function as redistribution
of property such as correction with tax payment amount.
The previous studies have analyzed the inequality of assets and incomes using the
Gini coefficient. However, the analysis on the index with gift tax is not progressing.
Therefore, the purpose of this paper is to analyze redistribution effect and to clarify
complementary elements with Gift tax on inheritance tax.
