This study explores a possible risk of overseas investment in long cross-national distance host countries using the foreign direct investment (FDI) data in Japan. We expect that increasing cross-national distance would relate to the less sustainable tax policies by increasing the differences in economic, political, administrative, cultural, demographic, knowledge, and geographic perspectives, which enhance the motivation of tax aggressiveness and the likelihood of earnings management. Consistent with our expectations, we find that firms with longer cross-national distance are less likely to adopt sustainable tax policies. After some robust tests, our main findings remain unchanged. In additional analysis, we find the above relation is weakened when firms invest in a tax-haven country or have a high proportion of foreign ownership, while it is strengthened when firms meet an earnings benchmark. Overall, our results suggest the one risk of increasing cross-national distance between host country and home country is less sustainable tax policies.
