Tax rates are to be revised in stages
Through the FY2017 Tax Reform, the structure of tax rates for liquors was significantly revised from the perspective of restoring tax burden fairness between. different types of liquors. Tax rate revision is to be enforced on October 1, 2020, but a sufficient transitional period up to October 1, 2026, is set and the revision is to be implemented in stages. For example, the basic tax rate for fermented liquors is uniformly set at 100.000 yen/kl with the aim of eliminating the tax rate difference between wine and refined sake. Therefore, the tax rate for wine, which is currently 80.000 yen/kl, is to be raised in stages.
