Cash ISAs

Shut for two reasons, and the second one outlives the first. Moneyfarm decided not to accept further US persons as customers and names the FATCA reporting burden as the reason, counting citizens, green card holders, people born in the States and dual nationals. Separately, this is not a deposit account: the money sits in qualifying money market funds, so even if the door opened it would be a fund holding and a PFIC on your US return, which is the opposite of what a cash ISA is for.

Moneyfarm stopped taking US persons in 2021 and names the FATCA reporting burden as the reason, counting citizens, green card holders, people born in the US and dual nationals. Clients from before then are grandfathered only while they stay in the UK, and must close on leaving.

Worth reading as a warning about how these bars are published. Moneyfarm's account opening clause carries no US person test at all, so the contract alone would tell you the door is open. Its FAQ closes it: Moneyfarm decided not to accept further US persons as customers, counting citizens, green card holders and anyone born in the States. Only people who opened before March 2021 are carried on, and only while they live in the UK.

Account names link to the provider's own site. momo has no active affiliate partnerships; if that changes it will be disclosed and will never change a verdict. Every institution, A to Z.

Confirm your own position with a cross-border specialist. Acceptance policies and tax rules change, and your facts may differ from the general case. Rates and terms here are the provider's published figures rather than an offer, and the provider decides each application on its own criteria. Use this as a map, not a ruling. Last checked .
Tax

ISA US tax

The IRS does not recognise the ISA wrapper. Cash ISA interest and stocks ISA gains are taxable on your US return, and fund holdings drag in PFIC rules.

 Tax

FATCA

FATCA makes UK banks report accounts held by US persons to the IRS. It is not a tax; it is a reporting trail. Where it bites is access.

 Tax

PFIC

Almost every UK-domiciled fund is a PFIC, taxed by the US at punitive rates with heavy filing. This is why US citizens hold individual shares, not UK funds.

 Tax

SIPP US tax

The treaty generally lets a UK SIPP grow tax-deferred for US purposes, but the protection has limits. How the US treats contributions, growth and drawdown.
