Did you spend any time in the US in 2017 or 2016? If so, how many days in each year?
Unfortunately no, I didn't...
Ultimately I'm trying to figure out if you're resident in the US as the during this period of US residency the income from this work could be exempt in the UK under treaty.
This is useful to know because I am now doing a similar internship from September 2019 to March 2020. But I guess I still wouldn't qualify for US residency because it works in calendar years, is that right? (I didn't stay in the US between both internships)
If not you'd likely get a foreign tax credit for the federal and in some cases, state tax that was due on this income (from the US and state tax returns, not your W2)
That makes sense! I am guessing I should just file a (late) Self Assessment tax return for this?
As a general question, would you bring this kind of questions to HMRC directly? For example, about interpreting an ambiguous residency if I meet the criteria of both countries.
Thanks again!
