US persons: no US rule published either way, so get it confirmed

The ISA terms set eligibility at 18 or over and resident in the UK, with no US person clause, and the general terms are equally silent, so nothing published stops you. Its share dealing material historically said US citizens complete a W-9 rather than a W-8BEN, which points to US persons being onboarded, but that page has been consolidated away, so confirm before subscribing. The stocks and shares ISA is not on the free Core plan: it needs Plus or Premium, and dropping back to Core means closing or transferring it out.

US persons: no US rule published either way, so confirm before you apply

Its terms set two conditions to open a general investment account, being 18 or over and resident in the UK, and never mention US persons, citizenship, tax residency or FATCA anywhere. That is an absence of a bar rather than a written welcome, so treat it as unconfirmed and ask at application.

Updated

CMC Invest sells a Junior Cash ISA, not a Junior Stocks and Shares ISA. Its own account listing names five products: Junior Cash ISA, Flexible Cash ISA, Flexible Stocks and Shares ISA, SIPP and GIA, and the Stocks and Shares ISA has no junior equivalent among them.

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

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.

 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

Do UK banks report your account to the IRS? Yes, through HMRC, under FATCA. It is a reporting law, not a tax. Where it bites is access.
