Entity Formation
Non-resident founders face a structure decision that’s genuinely hard to unwind later. Here’s a practical framework for choosing between a US LLC, a US C-Corp, and a UK limited company.
A US Limited Liability Company is, by default, a “pass-through” entity for tax purposes — the LLC itself generally doesn’t pay federal income tax; profits pass through to its owner(s) and are taxed on their personal return instead. For a single-member LLC, that means the entity is by default disregarded for tax purposes entirely, and the owner reports the business activity directly.
For a non-resident founder, this default treatment is often misunderstood. Pass-through taxation doesn’t mean no US tax exposure — it means the tax obligation flows to the owner, who, if the LLC is engaged in a US trade or business, will typically still have a US tax filing obligation on that income, non-resident or not. The LLC also still needs an EIN, is still subject to state-level filing and franchise tax requirements depending on the state of formation, and non-resident-owned single-member LLCs have a specific IRS information-reporting requirement (Form 5472 alongside a pro forma Form 1120) that carries steep penalties for missing it — a requirement that catches a meaningful number of non-resident founders who were told LLC formation was the “simple” option.
A C-Corporation is taxed as its own entity, separately from its owners — the corporation pays corporate income tax on its profits, and shareholders are taxed again on dividends when profits are distributed. That “double taxation” is the trade-off most founders are warned about, but it’s frequently the right trade-off in specific circumstances: venture-backed startups (most US institutional investors expect a Delaware C-Corp, structurally), businesses planning to reinvest profits rather than distribute them, and businesses that want the clean cap-table and equity-incentive mechanics a corporation offers.
For a non-resident founder specifically, a C-Corp also avoids some of the LLC’s pass-through complexity — there’s no personal US filing obligation purely by virtue of ownership, since the tax sits at the corporate level. The trade-off is more formal corporate governance (a board, minutes, formal share issuance) than an LLC typically requires.
A UK limited company is closer in structure to a US C-Corporation than to an LLC — it’s a separate legal entity, pays UK Corporation Tax on its profits, and its owners are taxed separately on dividends received. There’s no UK equivalent to the US LLC’s pass-through default; every UK limited company is taxed as its own entity from the outset.
For a non-resident director or shareholder, a UK limited company is generally straightforward to form — Companies House registration doesn’t require UK residency — but non-resident directors should be aware that the company will still need a UK registered office address, will have UK Corporation Tax and annual filing obligations regardless of where the directors live, and that dividends paid to non-resident shareholders can carry withholding or reporting implications depending on the shareholder’s own country of residence and any applicable treaty.
A handful of practical issues come up repeatedly with non-resident founders, regardless of which structure they choose:
Getting an EIN without a US Social Security Number is possible but requires a specific IRS process (Form SS-4 filed by fax, mail, or via a third-party designee) that takes materially longer than the instant online EIN issuance available to US residents.
US business banking has become genuinely difficult for non-resident founders to access directly with a US bank; most rely on a fintech provider or a US-based partner/registered agent relationship to open an account.
A UK company still needs a UK registered office — a residential address abroad doesn’t satisfy this, and most non-resident directors use a registered office service rather than attempting to use a personal address.
The Form 5472 filing requirement for non-resident-owned single-member US LLCs is frequently missed entirely, because founders assume an LLC with no US tax due has nothing to report — the informational filing is required regardless of whether tax is owed.
Founders building a business that will genuinely operate in both the US and UK — US customers and a UK team, or the reverse — often end up asking not “LLC or Ltd?” but “do I need both?” The answer depends on where you’re actually generating revenue, where your team and any employees are based, and where you expect to raise capital from.
A common structure for this situation is a parent entity in the market where fundraising is expected (often a Delaware C-Corp, if US venture capital is the goal) with a wholly-owned UK subsidiary handling UK operations and employment — or the reverse, with a UK parent and a US subsidiary, where the business is UK-led. Getting this ordering right at formation avoids a costly restructure later; getting it wrong is one of the more expensive mistakes to unwind once investors, contracts, and employees are already attached to the entity.
As a starting point, not a substitute for advice specific to your situation: if you’re a solo founder or small team, not planning to raise US venture capital, and comfortable with a personal US filing obligation, a US LLC is often the simplest route. If US institutional fundraising is the plan, a Delaware C-Corp is usually the expected structure regardless of founder residency. If your business is UK-led — UK customers, UK team, UK-based operations — a UK limited company is the natural base, with a US entity added only once there’s a genuine US operating or fundraising need.
The right answer depends on specifics — where you’ll actually do business, who you’ll raise from, and how you plan to take money out of the company — which is exactly the conversation worth having before you file anything, not after.
