If you are resident in the UK and control a US company, HMRC need to be told about it. https://www.gov.uk/guidance/controlled-foreign-company-an-ov...

The US company will pay 20% UK Corporation Tax on (worldwide) profits and need to fill out CT600 each year.

You will probably be able to pay lower taxes in the US as a result of double taxation treaties, but it's going to be a very tedious task to organise.

Aha, that's fair. Judging by the site it seems you'll have to take care to demonstrate that you're not shifting UK derived profits; but either way you'll want to chat up an accountant.

In my jurisdiction, to my knowledge and experience, they're considerably more lax.
