I am a US citizen that lived in the UK from 1/1/2016 to 3/31/2017. I used the physical presence test with the dates 1/1/2016 through 12/31/2016 for the foreign earned income exclusion in my 2016 tax return. For my 2017 tax forms, I would like to use the dates 4/1/2016 through 3/31/2017 for the physical presence test. Can I have such an overlap that (re)uses some of those dates in 2016 in my 2017 return even though I previously used them in my 2016 return ?
