Abstract

This study provides evidence that under the Japanese local individual income tax system, individuals smooth their after-tax income by choosing the timing of their tax payments. We construct a monthly data set of Japanese local taxes with sample periods for over 26 years. The results show that though the tax amounts are pre-determined in one-year units by the system, individuals pay more taxes during months when their incomes are high, such as in “bonus” periods, than other months in a year. The t-statistics for means indicates that there exist significant upward deviations during these months.
