> The "problem" you describe is your US citizenship requires you to pay tax on earnings from outside the US

No, I think you're missing the issue.

Suppose the company (let's call it XYZ Ltd) is owned 100% by my spouse. Let's say XYZ has $XYZPROFIT in one year. It then pays $XYZUKTAX on that profit, but the US isn't involved whatsoever. If it pays me $MYSALARY, XYZ reports that to the UK government and pays $MYUKTAX. I then report the US government $MYSALARY and $MYUKTAX, calculate $MYINCOME, and then calculate $MYUSTAX (which is normally $0, since UK taxes are higher than US taxes).

Now let's suppose I own more than 10% but less than 50%. Now I basically have to report to the US the same information about XYZ's financials that the company reports to the UK government, as well as answer 40-60 questions each of which would take a few days to understand the meaning of. Thankfully that's where it ends under normal circumstances; pay an accountant to prove you're not cheating the system and you're done.

Now suppose XYZ is 100% owned by me. It has $XYZPROFIT for the year, and pays $XYZUKTAX on that profit. Now, by default, $XYZPROFIT is included in $MYINCOME, but $XYZUKTAX is not included in $MYUKTAX; meaning by default I'm going to be double-taxed. I can avoid this, but only with 1) extra paperwork, and 2) forgoing any tax breaks for start-ups that the UK government has.

As I said, I don't mind paying taxes, but I don't want to pay it twice.
