Hi, I have a somewhat similar issue, but a bit more complex. I came to the US on L1 work visa from the UK in October 2017. Then in February 2018 I received a bonus from London for the portion of 2017 that I've spent there. It seems that now I need to pay taxes twice:
1) In the US, I am a tax resident in 2018 and therefore this UK income seems to be taxable, even thought it is technically a delayed pay for my 2017 work in the UK.
2) In the UK, the tax year is run differently (6 Apr 2017-5 Apr 2018), and I was a tax resident in the UK for that year (spent 200 days there). That bonus is paid for the work done in the UK by the UK company, so it is definitely table there as well.
Could you please help me understand this? It does not seem to be fair..
Thank you!
