Some ISA providers - including us - aren’t able to offer financial services to US citizens because of certain American tax rules.

For this reason, if you are a US citizen, including if you have dual nationality, you might have to close your account (which means you’ll pay the government’s 25% early withdrawal fee if your account is a Lifetime ISA).

If you're moving to the US and keep your ISA open while you live in the US, you’ll be taxed by the IRS on all money you hold in your account, including your bonus and any return on investments.
