I second this question. I may be doing a bit of freelance work w a US small non-profit (not a corporate company), which I'd do here in the UK, but the money would be deposited into my US bank account. It would be freelance income, ie I'm responsible for the taxes, and I would guess they'd send me a 1099 form at the end of the year.
My understanding is that any work done by us in the UK is declarable and taxable in the UK (you have to register as self-employed in the UK). That's fine.
But I also dont know if one would ALSO have to declare this income as "US income" on IRS forms.
I DO understand the concept that any money from work done in the UK is considered "worldwide income" by the US. But my question, like yours, is whether this kind of money is NOT considered exempted worldwide income by the IRS, but "US income", and thus taxable in the same way it would be if I'd earned it if I went to the US for a month and earned it.
Answers anyone?
