Declines US citizens
Updated

The accounts and the funds are both closed to US persons, defined to include any US citizen and any US passport holder wherever they live. Even without the bar this platform sells only Vanguard funds, so there would be no individual shares to fall back on.

Updated

Vanguard's client terms define Junior ISA as one of the products these terms cover, and the same terms bar US persons from its accounts and funds outright, defined to include any US citizen. The Junior ISA is held for the child's benefit, so the bar catches the child directly, whichever parent applies as registered contact.

Not offered
Updated

Vanguard does not sell a junior pension. Its client terms define Product as a Personal Pension, ISA, Junior ISA or General Account, an adult-only list with no children's pension in it, and no page on the site offers one.

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 US Treasury reads the treaty as leaving UK SIPP growth untaxed until drawn; the treaty's wording is narrower. Contributions, growth and drawdown explained.

 Tax

US-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.

Saving 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.
