US ETFs for UK Residents: PRIIPs, KIDs and the Workarounds

A UK resident usually cannot buy a US ETF on a UK platform because of the PRIIPs rules: a packaged fund sold to a retail investor needs a UK key information document, and US issuers do not produce one. The FCA's replacement regime, live since 6 April 2026, has not changed that in practice. The tax side matters just as much: a US ETF is an offshore fund for HMRC, and for an American it is the fund that avoids the PFIC regime.

This guide sets out what the regulators actually say in 2026, the routes people use, and how each one is taxed in both countries. It explains rules, not products: nothing here is a recommendation to buy, sell or hold any investment, and regulated investment advice should come from an FCA-authorised firm.

Why can't a UK resident buy US ETFs? PRIIPs and the missing KID

The short answer is disclosure. Under the UK version of the EU PRIIPs Regulation (packaged retail and insurance-based investment products), anyone selling or advising on a packaged product to a UK retail investor had to provide a key information document, or KID, prepared by the manufacturer. An exchange traded fund (ETF) is a packaged product. US fund managers write their documents for the US market (a prospectus and fact sheet regulated by the Securities and Exchange Commission) and have generally not produced UK or EU KIDs.

Without a KID, a UK investment platform cannot put the fund in front of a retail customer. That is why a search for a well-known US-listed ETF on a UK app usually returns nothing, or a message that the product is not available to retail clients, even though the same platform will happily sell you individual shares listed on the New York Stock Exchange or Nasdaq. Individual company shares are not packaged products, so the KID requirement never applied to them.

There is a second, separate barrier. US ETFs are collective investment schemes that are not authorised or recognised in the UK, so the financial promotion rules restrict marketing them to the UK public. The FCA itself makes this point, as the next section shows.

What did the FCA's Consumer Composite Investments regime change?

The UK has replaced PRIIPs with its own regime for consumer composite investments (CCIs). The legal framework is the Consumer Composite Investments (Designated Activities) Regulations 2024, amended by a 2025 Order that came into force on 6 April 2026. The FCA published its final rules in Policy Statement PS25/20 on 8 December 2025.

The timeline set out in PS25/20 is:

1. 8 December 2025: the FCA publishes its final CCI rules.
2. 6 April 2026: the CCI legislation commences and a transitional period begins. Manufacturers may produce the new CCI product summary or keep using their existing KID (or UCITS KIID).
3. 8 June 2027: the CCI regime goes fully live. Firms in scope must use the product summary; the old KID and KIID can no longer be used.

Crucially, the FCA has confirmed that the product summary remains the manufacturer's job. An earlier proposal to let distributors write their own summaries was dropped, so a UK platform still cannot fill the gap by producing a document for a US fund itself.

Does the CCI regime let UK investors buy US ETFs?

Not on its own. Respondents to the FCA's consultation raised exactly this point, saying the KID requirement had kept UK retail investors out of US ETFs and that a product summary requirement would do the same. In PS25/20 the FCA replied that its rules "do not create a barrier for retail consumers to access US ETFs", and explained the real gatekeeper: an overseas fund can only be marketed to UK retail investors if it is a recognised scheme, through the Overseas Funds Regime or section 272 of the Financial Services and Markets Act 2000, and there are currently no US funds that are recognised schemes in the UK.

The FCA adds that the CCI regime's flexible format should make it easier for overseas firms to market in the UK, and that entering the UK retail market is a commercial decision for those firms. So the door is not locked by the new rules, but someone has to walk through it: a US issuer would need UK recognition and a product summary before UK platforms could offer its ETF to retail clients. Until that happens, expect the practical position in 2026 and 2027 to look much as it did under PRIIPs.

The workarounds: routes, regulation and tax in both countries

People who want US market exposure while living in the UK tend to use one of the routes below. The table compares the regulatory position with the tax result in each country. The US column assumes the investor is a US citizen or green card holder; a British investor with no US status has no US filing for most of these, though US-situs estate tax can still apply (see below).

Route	Regulatory status in the UK	UK tax (UK resident)	US tax (US citizen)
US-domiciled ETF bought on a UK retail platform	Generally not offered: no KID or product summary, and not a recognised scheme	Offshore fund; gain taxed as income unless HMRC reporting fund status	Ordinary US fund; not a PFIC
UCITS ETF (Irish or Luxembourg) tracking a similar index	Widely available to retail clients with a KID or product summary	Offshore fund; many hold reporting status, so gains are usually capital gains	Usually a PFIC: Form 8621 and default excess distribution rules
UK-domiciled fund or investment trust	Available to retail clients	UK fund or UK company; capital gains treatment	Usually a PFIC, as a foreign pooled vehicle
Individual US-listed shares	Available to retail clients; not a packaged product	Foreign dividends and capital gains	Ordinary US shares; not a PFIC
Elective professional client status, then US ETFs	Possible if a firm agrees; retail protections given up	Same as a US ETF: offshore fund rules apply	Not a PFIC
US ETFs bought before moving and kept at a US broker	UK rules do not force a sale; the broker may restrict a UK-resident account	Same offshore fund rules from the date you become UK resident	Not a PFIC

The pattern is the uncomfortable one. For an American in the UK, the products that are easy to buy here are the ones the US taxes harshly, and the product the US treats normally is the one that is hard to buy here. Our article on why an ISA is a problem on a US tax return explains the PFIC side in detail, and our PFIC reporting service covers Form 8621 work.

Is professional client status a sensible route?

Professional client status removes the KID or product summary requirement because those rules protect retail investors only. It does not change the tax treatment, and it comes at the cost of protections. Some firms will only offer US ETFs to clients they have classified as professional.

An individual can only be treated as an "elective professional client" under COBS 3.5.3R in the FCA Handbook if the firm carries out an adequate assessment of their expertise, experience and knowledge, and, for this kind of business, the client normally meets at least two of three tests:

• carrying out transactions of significant size on the relevant market at an average frequency of 10 per quarter over the previous four quarters;
• a financial instrument portfolio, including cash deposits, exceeding EUR 500,000;
• working, or having worked, in the financial sector for at least a year in a professional position that requires knowledge of the transactions envisaged.

The client must ask in writing, the firm must give a clear written warning of the protections and compensation rights that may be lost, and the client must confirm in a separate document that they understand. In practice that can mean fewer disclosure and suitability safeguards, and the classification may cover more of the account than the ETF alone.

Holding US ETFs bought before you moved to the UK

The PRIIPs and CCI rules regulate firms that manufacture, advise on, offer or sell products to UK retail investors. They do not make it unlawful to own a US ETF, so moving to Britain does not oblige you to sell what you already hold. The friction is practical and fiscal.

On the practical side, many US brokers restrict or close accounts once a customer's address is outside the US, or allow sales but not new purchases. Policies differ between firms and change over time, so check your own broker's terms rather than relying on what worked for someone else. A UK platform that does not offer a US ETF to retail clients will often decline an in-specie transfer of it too.

On the tax side, the move changes how the same holding is taxed. Once you are UK resident, the offshore fund rules apply to any disposal, and the UK generally measures the gain from your original cost rather than from the value on the day you arrived. Two caveats: a qualifying new resident may be able to claim the four-year foreign income and gains regime, and if you later leave and return within a short period the temporary non-residence rules can bring gains back into charge. Our guide to cross-border investor tax reporting covers the annual filings that come with a US brokerage account held from the UK.

Illustrative example: an American moves from Boston to London holding a US-domiciled S&P 500 ETF bought years earlier, and the fund does not appear on HMRC's reporting fund list. Three years after becoming UK resident, she sells it at a gain. On her US return the sale is an ordinary long-term capital gain on Form 1040. On her UK return the same gain is an offshore income gain, charged at her income tax rates on the SA106 foreign pages, with no capital gains annual exempt amount, and her pre-move growth is included. The two countries see different kinds of income, so the foreign tax credit calculation needs care to avoid paying twice. Had the fund held reporting status throughout, the UK would have treated the gain as a capital gain instead.

How is a US ETF taxed in the UK? Offshore funds and reporting status

A US-domiciled ETF is an offshore fund for UK tax. Section 355 of the Taxation (International and Other Provisions) Act 2010 defines an offshore fund as a mutual fund constituted by a body corporate resident outside the UK, a non-UK resident unit trust, or certain other co-ownership arrangements under foreign law. US ETFs fit that description.

HMRC's helpsheet HS265 Offshore funds (updated 6 April 2026) explains the two treatments:

• Reporting funds. The fund reports its income to HMRC and investors. You are taxed each year on your share of the reportable income, including any "excess reportable income" that the fund kept rather than paid out. When you sell, the gain is normally a capital gain.
• Non-reporting funds. You are taxed only on income actually distributed, but when you sell, the gain is normally an "offshore income gain" charged to income tax rather than capital gains tax.

Distributions are taxed according to the type of fund. A fund that is a company is generally treated as paying dividends, but a fund with more than 60% of its investments in interest-bearing assets is treated as paying interest. Both are reported on the SA106 foreign pages; see our guide to SA106 foreign income for where each figure goes.

To check a fund, use HMRC's list of approved offshore reporting funds, a spreadsheet updated monthly and searchable by fund name and ISIN or CUSIP. Some US-domiciled ETFs have obtained reporting status and many have not. What counts is status for each period of your ownership, not just today's listing.

What does the US side look like for an American?

For a US citizen or green card holder, a US-domiciled ETF is the simple case. The PFIC regime applies only to foreign corporations that meet the passive income or passive asset tests set out in the IRS instructions for Form 8621 (revised December 2025), so a US fund is outside it. Dividends and gains go on Form 1040 in the usual way.

The reverse is where Americans in the UK get caught. UCITS ETFs and UK funds are foreign pooled vehicles and are usually PFICs, which means annual Form 8621 filings and, without a valid election, gains taxed as ordinary income, much of it at the highest rate for earlier years, plus an interest charge. Where both countries tax the same gain, relief comes through the treaty and foreign tax credits; our article on double taxation relief between the US and UK explains the mechanics.

For a British investor with no US status, there is no PFIC issue and no Form 1040, but US shares and US-domiciled funds are US-situs assets. The IRS says the estate of a non-resident non-citizen must file a US estate tax return when US-situated assets exceed $60,000 at death, and US corporate stock counts.

What people get wrong about US ETFs in the UK

• "PRIIPs has gone, so I can buy US ETFs now." The rules changed on 6 April 2026, but KIDs remain usable until 8 June 2027, product summaries must still come from the manufacturer, and the FCA says no US funds are recognised schemes.
• "Opting up fixes the tax problem." Client category affects regulation only. A US ETF is an offshore fund for HMRC whoever sold it to you.
• "A UCITS version of the same index is equivalent." For UK tax it is often better, because many hold reporting status. For a US citizen it is usually worse, because it is a PFIC.
• "My old US holdings are grandfathered for UK tax." There is no general grandfathering. The offshore fund rules apply to disposals once you are UK resident.

Choosing a route with both tax systems in view

The right structure depends on citizenship, how long you expect to stay in the UK, the size of the portfolio and whether accounts are held in the US, the UK or both. Investment selection belongs with a regulated adviser; the tax modelling is what we do.
