I've tried to find the answer but it seems like nobody's situation ever fits mine so I'm trying to figure this one out.
I'm a U.S. citizen. My wife is JP citizen. I want to buy an apartment cash and live in Japan. I'll be planning to immigrate on a spouse visa, but whether I'll get permanent residency depends on the tax implications.
My work is in a U.S. territory, Guam. I'll be working for an American company based there, getting paid USD, with a W-2 and all that. If we're talking a split, likely 100 days a year in the U.S., 180 days a year in Japan, and 80 days a year traveling to other countries.
My question is, will Japan tax this American income? Will they even know about it? I won't be earning anything in Japan at all. What about anything my wife does — are we seen as filing jointly like in the U.S. or as individuals with our own tax liability?
How about other sources of income? Like say, my military pension, mutual fund dividends, or eventually, social security?
