Am I Eligible for the FEIE for 2017?

[Slowtraveler]

This is the place that inspired me to move abroad in the first place so I wanted to ask something as a fascinating new realization struck me.

I just realized I may be eligible for the FEIE since we get to decide our dates based on the tax year ending on October 15. I left the states on September 21st, 2017 and haven't spent a day in the states since then. I took the FTC on some investment income but I believe this won't affect anything. By September 2018, I will have been abroad for over 330 days and the 2017 tax year will still be fileable. Does this make it so I can claim the FEIE for 2017?

Figured out that I am eligible but only on a prorated amount. Now to figure out if prorated means prorated of the tax brackets or if I only get to use the smallest brackets.

Prorated means by date. All income earn d before 9/21/17 is US earned income and taxed accordingly. If you have earned income in the following quarter then it can be excluded.

The Excluded income effectively fills up the lower brackets first / non-excluded income is taxed as if the FEIE didn?t exist
