Japan’s 2019 tax reform consists of sales tax，personal income tax，corporate tax and other taxes. Sales tax rate increase is the core issue of tax reform in Japan. In order to alleviate possible impact of sales tax hike on Japan’s economy in October 2019，the government has formulated a series of countermeasures，including introduction of preferential tax rate，substantial reduction of automobile tax，and further expansion of individual tax deduction for residential loans. Meanwhile，corporate tax and international tax are also important aspects of Japan’s tax reform in 2019.
