Hi, I am a British citizen and a permanent, full-time employee at a UK organisation. I left to work for a US organisation from 1st Sept. 2022 with leave from my current employer. I have worked in the US for full-time until 30 June, 2023 and have returned to UK now. I started working with my UK employer from 1st July 2023. During the 2022-23 tax year, I have paid UK tax for the months between April and August, 2022. During my overseas work between Sept. 2022 and June 2023, I was exempted from US Federal Tax due to UK-US Tax Treaty, but had to pay the State Tax. My question is, do I qualify for the 'split year treatment' for overseas work during tax year 2022-23. If yes, what do I need to do next. I would really appreciate any suggestions.
