Declines US citizensFidelity's client terms restrict accounts to UK residents over 18 who are not US persons, and the definition covers any US citizen and any US passport holder wherever they live. It also reserves the right to sell your investments and close the account if it merely suspects you will become one.

Junior SIPPs
Compare with other providersThe same Fidelity client terms bar US persons from its products and services, and the Junior SIPP account is held in the child's name, so the bar catches the child as the account holder regardless of which parent or guardian applies to open it.

Why this is the rule
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.
TaxSIPP US tax
The US Treasury reads the treaty as leaving UK SIPP growth untaxed until drawn; the treaty's wording is narrower. Contributions, growth and drawdown explained.
TaxUS-UK tax treaty
The US-UK treaty stops most double taxation, but the saving clause lets the US tax its citizens almost as if it were not there. What survives the clause.
TaxSaving for a child
How the US taxes a Junior ISA, a junior pension and a Child Trust Fund held by a US citizen child in the UK, and how a 529 plan compares.
