What Capital Gains will apply when I sell my USA home, to return to live in the UK?

My husband and I live and work in the USA and own and live in a property as our main home there. We are moving to the UK next year. We own 2 properties in the UK, will this affect what Capitol gains we pay?

Hi S Starling,
HMRC cannot comment on future events as legislation and/or plans may change.
However, based on current guidance you would need to determine which property is in fact your main residence:-
CG64485 - Private residence relief: only or main residence: two or more residences: right of nomination
Thank you.
