US LLC for UK Residents (2026): HMRC + IRS Obligations Explained

For most countries, the advice on US LLCs is straightforward: file the US paperwork, declare the income at home, done. The UK is different. HMRC and the IRS disagree about what a US LLC even is and that disagreement can turn a structure that works beautifully for an Indian or Sri Lankan founder into a genuine double-tax trap for a UK resident.

Most British founders discover this after forming the LLC, when an accountant mentions a Supreme Court case called Anson and the conversation gets complicated. The good news: the problem is well understood, and for many UK founders the LLC still works fine. The key is knowing which camp you are in before profits build up.

This guide covers the US filings your LLC owes (the same ones behind the foreign-owned LLC filings we prepare), then explains the HMRC mismatch in plain English. The UK-side analysis is orientation only this is one of the few areas of cross-border tax where specialist UK advice is genuinely essential, not just a disclaimer.

The Short Answer: It Works, But the UK Has a Trap Others Don’t

UK residents can legally own US LLCs, and thousands do for Stripe and US payment access, US client onboarding, USD banking, and Amazon US storefronts. The US side is identical to every other country: information filings every year, usually no US income tax for a services business with no US operations.

What is different is the UK side. Most countries look at a US LLC and tax its profits on the owner directly, the same way the US does. HMRC generally does not. That mismatch explained below is the single most important thing a UK founder needs to understand, and it is why the right structure for a UK resident is sometimes not an LLC at all. (For the baseline picture that applies to every nationality, see our complete non-resident LLC guide.)

The US Side: Exactly What You Must File

A US LLC owned by a UK resident with no US office, employees, or dependent agents typically owes no US income tax but it must file information returns every year, profitable or not:

The two facts UK founders most often get wrong: “no US tax owed” does not mean “no US filing owed” Form 5472 is an information return and the $25,000 penalty applies even in a dormant year and the filing is triggered by reportable transactions between you and the LLC, so simply funding the company in year one already requires a filing. The official instructions are on irs.gov, and our Form 5472 guide covers the form in plain English. Before any of it, the LLC needs an EIN free from the IRS, no SSN required (see our EIN guide).

The HMRC Opacity Problem in Plain English

Here is the core issue. Tax systems classify foreign entities as either transparent (look through the entity; tax the owner on profits as they arise) or opaque (treat it like a company; tax the owner only when it pays something out). The US and HMRC answer this question differently for the same LLC:

What Anson decided. In Anson v HMRC (2015), the UK Supreme Court found that a UK-resident member of a Delaware LLC was entitled to treaty relief because, on the facts found in that case, the LLC’s profits belonged to its members as they arose effectively a transparent result, and a win for the taxpayer.

What HMRC does anyway. HMRC’s published position (in its International Manual) is that Anson was specific to its facts and that HMRC will generally continue to treat US LLCs as opaque for UK tax purposes. In practice, most UK accountants report LLC distributions as foreign dividends unless the client is prepared to argue an Anson-style transparent position which is uncertain, fact-specific, and can cut both ways.

Why this can mean double tax. The risk is sharpest when US tax actually gets paid on the LLC’s profits for example, US-source income subject to withholding, US-connected business profits, or a UK owner who also has US filing exposure. The US charges tax on the profits as they arise to you; the UK charges tax on the distribution as a dividend from a company. Because the UK may not see those as the same income taxed twice, credit for the US tax may be restricted or unavailable, and the combined rate can climb well above what either country alone would charge. For the common case a UK-owned services LLC with no US tax liability at all there is no US tax to lose credit for, and the practical result is usually “UK tax on what you draw out, US information filings every year.” But timing mismatches and retained profits still need thought. This is exactly where specialist UK/US advice is essential the analysis depends on your LLC agreement, your state, and your numbers, and HMRC has consulted on reforming this area, so the rules may yet change.

Who Should Still Use an LLC and Who Shouldn’t

The opacity problem is not a reason for every UK founder to avoid LLCs. It is a reason to match the structure to the situation:

• LLC usually works: payment-access businesses. If the LLC exists mainly to run Stripe, receive USD from US clients, or operate a US storefront and you draw the profits out regularly rather than accumulating them the typical outcome is UK tax on your drawings and no US income tax. Many UK freelancers and e-commerce sellers run this happily for years.
• Think harder: profits left in the LLC. Opaque treatment means UK tax generally waits for the distribution which sounds nice until years of retained profit come out at once, or the facts create US tax with no matching UK credit. Retention strategies need advice.
• Consider a UK Ltd instead. If your clients and life are UK-centred and US payment access is not the driver, a UK Ltd avoids the classification mismatch entirely and keeps everything in one system HMRC understands.
• Consider a US C-corp. If you will raise US venture capital or want unambiguous company treatment on both sides, a Delaware C-corp is opaque to everyone the US and the UK agree on what it is, and the US–UK treaty works cleanly for dividends. The cost is US corporate tax and more filings.

Worked Example: A $60,000 Year Through an LLC

Say you are a London-based consultant with a single-member Wyoming LLC. In 2026 it bills US clients $60,000, spends $5,000 on software and fees, and you transfer $40,000 to your UK account during the year, leaving $15,000 in the LLC. Illustrative treatment (your adviser runs the real numbers):

• US side: No US income tax (services, no US operations facts-dependent). But the $40,000 of transfers and your initial funding are reportable transactions, so the LLC files Form 5472 + pro forma 1120 by April 15. Miss it and the starting penalty is $25,000 see our penalty guide.
• UK side, HMRC’s default view: the $40,000 you drew is a distribution from an opaque entity broadly, foreign dividend income on your Self Assessment, with dividend rates applying. The $15,000 retained is not yet taxed in the UK on this view.
• UK side, transparent view (Anson-style): the full $55,000 profit is your income as it arises, regardless of what you withdrew. Which view applies to your LLC is precisely the specialist question.
• The trap scenario: if any US tax had been paid on those profits, dividend treatment in the UK could leave that US tax without a matching UK credit the double-tax risk this article exists to flag.

Common Mistakes UK Founders Make

• Skipping Form 5472 because “no US tax is owed.” Still the most expensive mistake. $25,000 per missed year, tax owed or not, and unfiled years stay open indefinitely.
• Assuming Anson settled everything. It held for the taxpayer on its facts; HMRC’s stated practice is still to treat US LLCs as opaque in general. Do not build a structure on a case your adviser has not applied to your facts.
• Letting profits pile up without a plan. Opaque treatment defers UK tax to the distribution then delivers years of it at once, at dividend rates, in one tax year.
• Not telling their UK accountant about the LLC. Worldwide income and foreign entities belong in your Self Assessment conversation from day one, not after HMRC asks. Information-exchange agreements mean the LLC is visible.
• Mixing personal and LLC funds. Every transfer between you and the LLC lands on Form 5472, and messy accounts make the UK dividend-versus-transparent analysis even harder.
• Missing the multi-member deadline. Adding a co-founder converts the LLC to a partnership: forms change to 1065 + K-1s and the deadline moves up to March 15, with penalties of roughly $255 per partner per month. (Full picture in our foreign-owned LLC obligations guide.)

The Bottom Line

A US LLC can absolutely work for a UK resident but the UK is the one major country where the home-side treatment of the LLC itself is contested. HMRC generally sees an opaque company and taxes distributions like dividends; the US sees a transparent entity and expects Form 5472 + pro forma 1120 by April 15 (or 1065 + K-1s by March 15) every year, backed by a $25,000 penalty.

Frequently Asked Questions

Can a UK resident own a US LLC?

Yes. The US imposes no residency requirement on LLC ownership, and no visa or ITIN is needed to form one. The complications are on the UK tax side how HMRC characterizes the LLC not on the legality of owning it.

How does HMRC treat a US LLC?

Generally as opaque like a company. HMRC’s published guidance treats the Anson decision as fact-specific and continues to regard US LLCs as opaque, meaning members are typically taxed on distributions (broadly like dividends) rather than on profits as they arise. Your facts may support a different position specialist advice territory.

Will I be taxed twice on US LLC income as a UK resident?

Possibly, in specific situations. If US tax is paid on the LLC’s profits while the UK taxes your distributions as dividends, the UK may not give full credit for the US tax, because the two countries are taxing different things. Where the LLC owes no US income tax at all the common services case the double-tax risk is much smaller, but the analysis should still be done professionally.

Do I still need to file US forms if my LLC owes no US tax?

Yes, every year. A foreign-owned single-member LLC files Form 5472 with a pro forma 1120 by April 15 (extendable to October 15); a multi-member LLC files Form 1065 with K-1s by March 15. These are information returns the $25,000 penalty applies regardless of whether any US tax is due.

Should a UK founder pick an LLC, a UK Ltd, or a US C-corp?

LLC for US payment access with regular profit drawings; UK Ltd if the business is UK-centred; C-corp if raising US venture capital. The LLC’s classification mismatch is manageable for simple cases but a real cost for profit-retention strategies. Model your actual numbers with a UK/US adviser before choosing.

What is Anson v HMRC in one sentence?

A 2015 UK Supreme Court case in which a UK member of a Delaware LLC won treaty relief because the profits were found to belong to members as they arose a transparent result that HMRC treats as confined to its facts, which is why the opacity question remains live for every other LLC owner.
