I have an offer from my employer to move to New York, but I am concerned about what happens when I choose to return home to the UK. I understand that there is a double taxation treaty between the UK and the USA, but what's not clear is what happens I return home.
It seems I will have to continue filing US Tax returns for a couple of years after I return to the UK, but there seems to be no indication of what, if any, US tax I will have to pay even though I will not be earning in the USA.
Will the IRS try to tax me on my UK income after I return? What's the point of asking me to file a tax return when I will not be working in the US?
