>>11929761I am so damn tired of stupid anons spouting crap without checking publicly available information.
An approved tax treaty between Japan and the United States is in place. It helps a taxpayer decided which country to pay taxes to, when the taxes are due, and helps prevent dual taxation. In most cases, residency status is what determines the country that receives the taxes.
And only non-residets are paying additional taxes in Japan(10%) and if you think she is not a Japanese resident after living there for about 10 years then you are probably underaged, honestly, your whole post reeks acne.
