Good day. I am a US citizen who has been living abroad for the past decade. I have filed joint tax returns but have not had to pay any taxes. Now I am about to take up a one year visiting position at a US university and will be receiving a grant through a non profit which covers living expenses, housing, transportation, schooling costs, cost of a research assistant, university health insurance, car leasing purchase. The state I plan to move to has state income tax. Also, I do not have any income, savings or major assets and have personal loans from individuals to the tune of USD$10K. My wife is not currently employed. What is taxable and what isn't? Is there any way not to pay any taxes or at least to pay a token amount? Thanks.
