US LLC vs UK Ltd for an Online Business
If you are running an online business from Europe and weighing a US LLC against a UK Ltd, the right answer depends less on which country sounds more impressive and more on where your customers, payments, and tax residency actually sit.
The short answer
Neither structure is universally better. A US LLC tends to suit founders who sell mainly to US customers, want US payment processors and marketplaces to treat them as a domestic business, and want a fast, low cost, fully remote setup. A UK Ltd tends to suit founders who are based in or trading substantially with the UK, need to register for UK VAT, hire UK staff, or want the credibility of a UK registered company for UK clients and banks.
Most European founders selling digital products, SaaS, or services to a global or US-heavy audience choose a US LLC for the banking and payments advantage, then rely on their home country tax return to handle personal tax. Founders whose customers and operations are genuinely UK-based often find a UK Ltd simpler because everything, tax, banking, invoicing, lives in one jurisdiction.
What each structure actually is
US LLC
A Limited Liability Company is a US state-level entity. It is not taxed at the federal level by default. A single-member LLC owned by a non-US person is treated by the IRS as a 'disregarded entity', meaning its activity is reported on the owner's return rather than the LLC filing its own corporate tax return, with one important exception explained below. Wyoming is the most common default state for foreign founders because it has no state income tax and low, predictable annual fees. Delaware is popular for venture-backed companies but carries a franchise tax and higher annual costs.
UK Ltd
A private company limited by shares is registered with Companies House and is UK tax resident. It pays UK Corporation Tax on its profits, files annual accounts and a confirmation statement with Companies House, and files a CT600 Corporation Tax return with HMRC every year, even in a loss making year. Directors and significant shareholders appear on the public register.
Side by side comparison
| Factor | US LLC (foreign owned, single member) | UK Ltd |
|---|---|---|
| Setup speed | Often a few business days once documents are ready | Usually same day to a few days via Companies House |
| Remote setup for non-residents | Fully remote, no visit or visa required | Fully remote, no visit required |
| Ownership privacy | Member details often not on a public state register (varies by state) | Directors and persons with significant control are public |
| Default annual cost | Low in states like Wyoming; higher in Delaware due to franchise tax | Filing fees plus accountant fees for accounts and CT600 |
| Federal tax if no US trade or business | Can be zero, but informational filing is still mandatory | Corporation Tax applies to profits regardless of where the owner lives |
| VAT | No VAT system; US sales tax rules are separate and state based | UK VAT registration required once turnover crosses the current threshold |
| US bank accounts, cards, Stripe/PayPal fit | Generally straightforward with an EIN | Possible but often treated as a foreign entity by US platforms |
Taxes: the part people get wrong
A foreign owned, single member US LLC that has no employees, no physical presence, and no 'effectively connected income' in the US can often owe no US federal income tax. That surprises people, but it does not mean there is nothing to file. Every foreign owned single member LLC must file Form 5472 together with a pro forma Form 1120, every year, even when there is zero income. Form 5472 is an information return, it reports transactions between the LLC and its foreign owner, it does not itself calculate or collect tax. Missing this filing carries a penalty of $25,000, so it is not something to skip just because there was no revenue.
A UK Ltd, by contrast, is UK tax resident from the day it is incorporated and pays Corporation Tax on its worldwide profits, and files with HMRC and Companies House annually regardless of where the director lives.
In both cases, you as an individual will usually still owe tax in the country where you actually live and work. Neither structure is a way to avoid personal tax obligations in your home country, and this article is not tax advice. Speak to a qualified accountant in your country of residence before finalising a structure.
The structure decides where the business is taxed and banked. It does not decide where you, personally, owe tax. That is determined by where you live and work.
Banking and payments
This is often the deciding factor for online founders. A US LLC with an EIN can open US business bank and card accounts remotely through providers like Mercury, Wise, or Relay, none of which require a US visit. That gives you a US routing number, US denominated accounts, and business credit or charge cards, which makes life easier with US focused payment processors, ad platforms, and marketplaces that sometimes treat foreign registered companies as higher risk or restrict certain features.
A UK Ltd banks naturally within the UK system and works well if your revenue, suppliers, and customers are UK based. If a significant share of your revenue comes through US platforms, though, a UK Ltd can sometimes face friction that a US LLC does not.
Compliance workload
US LLC: annual state filing (often called an annual report), a registered agent in the formation state, the Form 5472 plus pro forma 1120 filing, and an EIN obtained via Form SS-4. If you personally need to file a US tax return, you will also need an Individual Taxpayer Identification Number, which does not require a visa and is issued to people who are not eligible for a Social Security Number.
UK Ltd: annual accounts, a confirmation statement, a CT600 Corporation Tax return, and VAT returns once registered. The workload is broadly comparable, the difference is which country's paperwork you are dealing with and whether that matches where your business actually operates.
Which one fits your situation
- Choose a US LLC if most of your customers, ad spend, or platform relationships are US based, or if you want US bank accounts and cards without opening a UK entity.
- Choose a UK Ltd if you live in the UK, sell mainly to UK or EU customers, need to register for VAT soon, or plan to hire UK based staff.
- Some founders eventually use both, a UK Ltd for local operations and a US LLC for US facing payments, though that adds complexity and cost, so it is worth doing only when there is a clear operational reason.
Founders Credit sets up the US side of this done for you, the LLC formation, EIN, ITIN if needed, and a US business bank account and cards, entirely remotely, so you can make the structural decision without getting stuck on the paperwork.
Glossary
Disregarded entity: a single member LLC that the IRS treats as not separate from its owner for federal income tax purposes, so profits flow to the owner's return instead of the LLC filing its own tax bill.
EIN: Employer Identification Number, the US tax ID for a business, obtained via Form SS-4 and available to non-residents without a Social Security Number.
ITIN: Individual Taxpayer Identification Number, issued to individuals who need to file a US tax return but are not eligible for a Social Security Number. No US visa is required to get one.
Form 5472: an annual information return required for foreign owned single member LLCs, filed with a pro forma Form 1120, carrying a $25,000 penalty for late or missing filing.
Registered agent: a person or company with a physical address in your formation state who receives legal and state correspondence on your LLC's behalf.
Companies House: the UK's registrar of companies, where UK Ltds file incorporation documents, accounts, and confirmation statements.
Frequently asked questions
Can a European resident own a US LLC without visiting the US?
Yes. Non-residents can form, own, and run a US LLC entirely remotely, including getting an EIN and opening a US business bank account with providers that support remote onboarding. No visa or US visit is required.
Do I still need to pay tax in my home country if I open a US LLC?
Almost certainly yes. Where the LLC is registered does not usually change where you personally owe tax, which is generally determined by your country of residence. Check with a local accountant on how LLC income is treated where you live.
What happens if I forget to file Form 5472 for my LLC?
The IRS can impose a penalty of $25,000 for failing to file Form 5472 and the accompanying pro forma Form 1120, even if the LLC had no income that year. This filing is mandatory annually for foreign owned single member LLCs.
Is a UK Ltd more credible to customers than a US LLC?
It depends on your audience. UK customers and B2B clients in the UK often find a UK Ltd more familiar, while US based customers, marketplaces, and payment platforms sometimes engage more smoothly with a US registered entity.
Which US state should I pick for my LLC?
Wyoming is a common, low cost default for foreign founders because it has no state income tax and simple annual filing requirements. Delaware is popular for companies planning to raise venture capital but carries higher ongoing franchise tax costs.
