Tax treatment, banking, compliance, and market access compared between the world's two most popular remote-founder jurisdictions.
A UK Ltd is a taxable corporation paying 19-25% corporation tax on all profit. A US LLC is a pass-through with no entity-level US tax - for a non-US resident with no US activity, the effective US tax can be 0%. US LLCs are harder to run (mandatory Form 5472 filings, EIN process) but unlock US banking, Stripe, and enterprise customer onboarding that UK Ltd cannot match.
The UK Limited company and the US Limited Liability Company are the two most chosen structures for international founders. They are both cheap, widely accepted, easy to form, and compatible with remote ownership. But they are fundamentally different tax animals, and choosing between them has long-term consequences for how much tax you pay, which customers you can win, and how complicated your compliance becomes.
A UK Ltd is a traditional corporation: separate legal entity, separate tax person. It pays UK corporation tax at 19% on profits below GBP 50,000 and 25% above GBP 250,000, with a marginal-relief taper in between. When it pays dividends, the shareholders are then taxed again in their country of residence. It is familiar, predictable, and universally understood.
A US LLC is a pass-through by default. The LLC itself pays no federal US tax. Instead, income "flows through" to the members, who report it on their personal returns in their country of tax residence. For a non-US resident with no US-source income and no US employees or office, this can mean zero US federal tax on the LLC's profits - an outcome that draws many international entrepreneurs to the structure.
This guide compares both vehicles across tax, banking, compliance, cost, market access, and the practical realities of operating them remotely.

The UK Limited company is a private company limited by shares, registered at Companies House. It is the simplest and cheapest formal business entity in any developed economy - GBP 12 online, 24-hour turnaround, no notary, no minimum capital, no local director, no mandated accountant. More than 500,000 new Limiteds are formed each year, of which a significant share are owned by non-UK residents.
The UK Ltd is a separate legal person from its shareholders. It owns assets in its own name, pays tax in its own name, and limits shareholder liability to paid-up capital. This corporate veil is well-established, enforcement-friendly, and widely respected by banks, clients, and counterparties.
Formation: GBP 12 online at Companies House (GBP 50 postal, GBP 100 same-day priority). Registered office service: GBP 40-100 per year if you use a London service address. Annual confirmation statement: GBP 34. Annual accounts filing: free if DIY using Companies House WebFiling, or GBP 200-800 if you hire an accountant. Corporation tax self-assessment is mandatory with HMRC. Dormant company accounts are simple and cheap; active trading companies require full accounting. Expect total annual running cost of GBP 200-1,000 for a typical non-trading or lightly trading Ltd.
UK corporation tax (from April 2023): 25% on profits above GBP 250,000, 19% on profits up to GBP 50,000, with marginal relief tapering between the two bands. There is no distinction between retained and distributed profit - tax is applied at the entity level on all profit. A UK Ltd must file a CT600 corporation tax return annually and pay tax within 9 months and 1 day of year-end (for SMEs).
Dividends paid to non-UK-resident shareholders do not suffer UK withholding tax (the UK has unusually friendly dividend WHT rules). Dividends paid to UK-resident shareholders trigger dividend tax at 8.75%, 33.75%, or 39.35% depending on income band, with a GBP 500 annual allowance. VAT is 20% standard; registration is mandatory above GBP 90,000 turnover.
A US LLC is a state-law entity typically formed in Delaware, Wyoming, New Mexico, or Florida. It combines the limited liability of a corporation with the tax simplicity of a partnership or sole proprietorship. By default under federal tax law, a single-member LLC owned by a foreign person is a "disregarded entity" - invisible to the IRS as a taxable person - and a multi-member LLC is a partnership, also a pass-through.
For international founders, the appeal is the combination of US banking, US payment processors (Stripe Atlas, PayPal Business, Shopify Payments), US brand credibility, and potentially 0% federal tax when structured correctly. The catch is that federal compliance requires IRS filings that must be done right: Form 5472 plus a pro-forma Form 1120 for every foreign-owned single-member LLC every year, with a USD 25,000 penalty per missed form.
Wyoming state fee: USD 102 formation + USD 60 annual report. Delaware state fee: USD 110 formation + USD 300 annual franchise tax. Registered agent: USD 50-150 per year. EIN application from the IRS: free (Form SS-4 by fax for non-residents, 4-8 week turnaround). Annual tax preparation: USD 500-1,500 if you hire a US accountant to file Form 5472 and Form 1120 pro-forma. Total first-year cost: roughly USD 300-800 plus tax prep.
A US LLC is a pass-through under default federal classification. For a single-member LLC owned by a non-US person, federal tax applies only to US-source effectively connected income (ECI). If the LLC has no US employees, no US office, and no US-sourced services - for example, a consulting LLC providing services to clients outside the US from an owner based abroad - then there is typically no ECI, no US federal tax, and no US state income tax (in no-income-tax states like Wyoming).
The mandatory IRS filings remain: Form SS-4 to get an EIN, annual Form 5472 (information return on foreign-related party transactions) paired with a pro-forma Form 1120. Failure to file Form 5472 carries a USD 25,000 penalty per form per year - this is the single biggest trap for international US LLC owners.
Your home country will tax the LLC's income in most cases. Depending on your country's tax rules, the US LLC may be treated as a pass-through (income taxed in your hands) or as a foreign corporation (income taxed when distributed). The UK, for instance, traditionally treats US LLCs as opaque, meaning the 25% UK corporation tax could apply to distributions. Always consult a local tax advisor before forming.
The right choice comes down to where your revenue is and which payment processors you need. If your business lives or dies by Stripe US and your customers are American, a Wyoming or Delaware LLC is the clear winner despite the IRS compliance burden. If your customers are European, UK, or global and you can invoice through Stripe UK or Wise, the UK Ltd is simpler, cheaper, and cleaner. Many international founders eventually run both - a UK Ltd as the operating company and a US LLC as the US-market invoicing entity - but for a single primary vehicle, let customer geography decide.
It depends on your client geography. If you serve US clients and need Stripe, Shopify, or enterprise contracts, a US LLC is better. If your clients are UK, EU, or global consulting, a UK Ltd is simpler and cheaper. UK Ltd costs GBP 12 to form; a US LLC costs USD 60-110 plus a registered agent.
A UK Ltd is taxed at the company level at 19-25% corporation tax. A US LLC is a pass-through by default - no entity-level tax, income flows to members taxed in their country of residence. For a non-resident with no US-source income, a US LLC can be genuinely 0% taxed at the US federal level.
Yes to both. UK Ltd founders use Wise Business, Revolut, Starling, Monzo, and Tide - typically opened in days without a UK visit. US LLC founders use Mercury, Relay, and Brex - usually opened online with video verification. Traditional high-street banks in both countries require a physical visit.
UK Ltd is dramatically cheaper at formation: GBP 12 online at Companies House. A US LLC costs USD 60-110 state fee plus a registered agent at USD 50-125 per year. However, a Wyoming LLC has lower recurring state cost (USD 60/year) than UK accounting typically runs.
Yes. Every US LLC with non-resident foreign owners must obtain an IRS EIN and file Form 5472 paired with a pro-forma Form 1120 annually - even if the LLC has no US-source income and no US activity. Penalties for non-filing are USD 25,000 per form per year.
Usually yes. If you live in one country and operate a US LLC from there, most tax authorities treat it as effectively taxable in your home country. Some countries (including the UK) may classify the LLC as opaque and tax dividends separately. Always consult a local tax advisor before forming.
