After reading through most of the posts on this thread, it seems pretty straightforward - I will need to file in the US.
I own a corporation that is domiciled in the US, so I will file taxes in the US accordingly. All of my clients are located in the US, they pay in USD, the money is held in US accounts, and I will account for the income in the US.
I will be living in the UK full time, beginning whenever my visa is approved, as a remote employee of the US corporation.
Does anyone know if I am required to file in the UK if my income is 100% US income?
