Dual-status tax filing
I was based in the US for 5 years on a J-1 visa and became a resident alien for tax purposes in 2016. I stayed in the US for an extra year and, due to visa restrictions, I was required to return back to my home country in September 2017.
I was in my home country for the remainder of 2017, so I assume this makes me a dual-status taxpayer? My assumption is that I was a resident for Jan-Sept and a non-resident for Oct-Dec. If so, there are very few resources that explain how to complete my tax return. I know that I will be required to paper file two tax returns (one for the resident portion and one for the nonresident portion). But if I earned no US income during my non-resident period, how do I complete the non-resident tax return?
Thanks for any help. US taxes are a nightmare to figure out, especially when you can't use those nifty online tools that do everything for you.
