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

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

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

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.
