Stocks and shares ISA for US citizens
Momo checked 47 providers. 46 offer a stocks and shares ISA; 1 no longer does. Of those 46, 1 will take you outright and 16 attach conditions. 29 refuse. Last checked .
The providers that refuse you outright are the simpler problem. The ones that do not are the harder one, because most will open the wrapper and then sell you nothing but investments the US taxes punitively. And the tax break you opened it for does not cross the Atlantic at all.
A stocks and shares ISA is the standard way to invest in Britain, and its whole point is the tax break: no UK tax on growth or income inside it. For a US citizen that break is half a break, because the US taxes its citizens wherever they live and the US-UK tax treaty does not recognise an ISA. HMRC honours the wrapper and the IRS looks straight through it.
That is not Momo's reading alone. Rathbones, which manages money for US taxpayers, lists among the key facts of its service that ISA income and capital gains are included in your US reports and are not tax exempt under US law. Canaccord Wealth goes further and files it under mistakes, naming "assuming UK tax-free wrappers like ISAs are also tax-free in the US" as a common error. Both will run an ISA for you. Neither pretends it does what it does for everyone else.
The second problem, which outlasts the first
US tax treats non-US pooled funds as PFICs, passive foreign investment companies, and taxes them punitively with onerous annual reporting on top. Nearly every ordinary UK fund and UCITS ETF is one. You cannot swap into US funds instead, because UK rules require a key information document that US-domiciled ETFs do not produce, and Lightyear states that plainly on its own pages. Inside an ISA, with no treaty protection, that combination is at its most expensive.
So the useful question is who will let you hold individual shares, which are not PFICs however many you own. Several providers that accept you fail on exactly this point. NatWest Invest offers five ready-made funds and nothing else. Sidekick's ISA holds two ETFs, even though its taxable account holds index constituents directly. An open wrapper full of PFICs is not a result.
Who refuses, and who is not who you think
Twenty-nine providers bar you, mostly on citizenship or birthplace rather than residence, so living in Britain helps at none of them. Bestinvest's test is the widest, turning on where you were born. Halifax, Lloyds and Scottish Widows all run on one platform and share one exclusion, so shopping between them achieves nothing. eToro's ISA is a Moneyfarm product, and Moneyfarm is closed to new US persons, so the brand on the app is not the firm deciding about you. IG will open the wrapper and then not sell you US-incorporated stock inside it, which is what most people wanted it for.
HSBC is the sharpest reminder to ask about the product rather than the bank. Its InvestDirect ISA carries no citizenship test at all, while its Global Investment Centre ISA says HSBC cannot open or maintain an account for a US person. One bank with two ISAs and opposite answers.
Do not check this by reading the terms
At Moneyfarm, True Potential, Wealthify, InvestEngine and Chip the contract sets a plain UK residence test and never mentions America, while the refusal sits in an FAQ, a help centre article or the application form. Reading the document you would actually sign gives you the wrong answer at all five. Where a row below rests on terms that are silent rather than welcoming, its note says so, because silence is not an offer.
Before opening one, read how the US taxes your ISA and what the PFIC rules do to UK funds. If you want a wrapper the treaty has an article for, that is a pension: see the pension page.
The accounts you can open
Read the "what you can hold" column before the fees. A US person is taxed punitively on non-US pooled funds, which the IRS calls PFICs, and nearly every ordinary UK fund and UCITS ETF is one. Unlike a pension, none of this is protected by the US-UK tax treaty, so an account offering only ready-made fund portfolios is open to you and close to useless to you.
Annual fee is shown as each provider charges it. Percentage charges and flat fees sort separately because they are not the same measurement: a percentage grows with your holdings and a flat fee does not, so above a certain balance the flat fee wins.
You can hold individual shares
Direct holdings in single companies, which is the way round the PFIC problem: the tax penalty falls on pooled funds, and a share in one company is not one.

The platform is offered only to people who are 18 or over, UK resident and not a US person, and you warrant that on an ongoing basis and must tell Quilter immediately if it changes. It does offer US shares, which is what makes the bar sting. Source: Quilter Invest app terms, clauses 3.3 and 12.2, 2026-08-17 (opens in a new tab) | |

No longer offering this, or never did
Nothing to do with your citizenship: these is one provider that does not offer a stocks and shares ISA to anyone in the UK. Several are still recommended in forums and guides, which is why they are listed rather than left out.

Common questions
Can a US citizen open a stocks and shares ISA?
Some UK platforms accept US persons and many decline, so this is the account type where the provider list matters most. The harder question is what you are allowed to hold once the account is open.
Is a stocks and shares ISA a good idea for a US citizen?
Only if you can hold individual shares in it. Nearly every UK fund is a PFIC for US tax, taxed at the highest ordinary rate with an interest charge and an annual Form 8621, and the ISA wrapper gives no US protection at all. A platform offering only ready-made fund portfolios will open an account for you and hand you a tax problem.
Can a US citizen buy US shares in a UK stocks and shares ISA?
At a provider that accepts you and offers individual shares, yes, and individual shares are not PFICs, so they avoid the problem UK funds bring. The frictions are the ones in the rows on this page. Hargreaves Lansdown has a US citizen file a paper W-9 in place of the online W-8BEN and gives no reduced treaty rate on US dividends. IG lets a US citizen buy US-incorporated stock only as a derivative, never through a share dealing account, which is what an ISA is. The wrapper gives no US shelter either way: the US taxes the dividends and gains as if the ISA were not there.
Does any stocks and shares ISA give a US citizen a 1099?
Interactive Brokers does. Its tax pages say it issues US persons a consolidated 1099, and holders of its ISA report receiving one for the ISA, with the 1099-DIV and 1099-B, since the 2023 tax year, though its support desk has told at least one customer otherwise. Other UK providers generally report a US person's account to HMRC under FATCA rather than sending a 1099, so the figures come from the annual statement. Either way the dividends and gains are taxable on your US return.
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.
TaxISA 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.
