I'll combine questions from both your posts:
Is it better to do bona fide or physical presence? In 2019 I was only out of the country for a total of 9 days. I’ve lived here since May 2018 so I’m thinking bona fide is better but not sure.
It's always better to use bona fide if you qualify. No hassle with meeting the required number of qualifying days. If the UK was your permanent residence for all of 2019, then you'll qualify.
In 2019 I was only out of the country for a total of 9 days.
Part VII line 38, I calculated my days as 356 (365 days minus the 9 days I visited the USA in 2019)
On line 39, do I enter 0.975?
As I understand it, but I'm just another punter like yourself:
If you were in the US on vacation for the whole time, and provided you do not claim the housing deduction or exclusion, then disregard those 9 days and enter "365" on line 38 and "1.000" for line 39.
If you were in the US and working in the US for those 9 days, then enter your calculation (0.975?) on line 39.
I have my 1040 ready and Schedule 1 is done as well just need someone to help me on this so I can post this and get it off my to do list
Don't forget Schedule B if you have any UK bank account, by yourself or jointly.
