I had to file US taxes this year even though I didn’t work in the States last year. It was fallout from when I was in Seattle because I still have an open bank account there. I originally intended to just ignore it (no income == no taxes!) but I received a form that outlined how much (little) I made on interest. So I planned to go through and file, but after closer inspection of what the actual codes on the form meant, it turns out the income was tax exempt. Anyways, I had already begun filling in my 1040NR-EZ form for non-resident aliens, so I finished it off. My postage of $1.78 cost more than the tax I had to pay, which came out to a big fat $0 on $0 of income. What a waste of a tax return.
