I am a US Citizen, but I live in work in Japan as a university professor. Next year, as a sabbatical, I will spend a year in US from Aug 2018-August 2019. As far as my understanding of residency, I will still be a Japan resident since my plan to be in the United States is clearly just the one year. So, I have a few questions: 1) can I still file for the FEIE (as I normally do each year) or do I have to file for foreign tax credit? 2) If I work in the United States during my sabbatical and earn income, does that change my filing in any way? 3) I also will have some capital gains from stock investments during that time...I already have to file for that, so I assume it wouldn't affect anything, but would it? 4)I want to use Turbo Tax to do my taxes next year and the year after. Can the system handle my type of situation?
