When to get professional help
These guides explain the rules. They cannot tell you the best move for your own money across two tax systems. For anything involving cross-border tax, pensions, or estate planning, consider a regulated financial adviser who specialises in UK-US planning, and a tax professional qualified in both countries. This site does not recommend specific firms; ask about relevant experience, fees, and regulation before engaging anyone.
