Forming a company in the United Kingdom from the United States is very achievable — but the UK filing is only one side of the structure. This guide covers both: the UK decisions, and what specifically changes because you are resident in the United States.
Can a founder in the United States form a company in the United Kingdom?
Short answer: yes — a US person can own 100% of a UK Ltd. The UK side is straightforward (identity verification + registered office); the bigger work is US reporting on your foreign company.

Why founders from the United States choose UK
US founders form a UK company to establish a UK/EU presence, invoice UK clients in GBP, hire locally and win trust with European customers.
Which company structure should you choose?
- Private limited company (Ltd) — the default: limited liability, shares, simple to run and well understood by banks and customers.
- LLP — a limited liability partnership, sometimes used by professional firms; profits are taxed on the members rather than the entity.
Foreign ownership, director and address requirements
There is no UK residency requirement for directors or shareholders, so a non-resident can own 100%. You do need a UK registered office (a real address, not a PO box), an appropriate email address, SIC activity codes and details of any Persons with Significant Control. Under the Economic Crime and Corporate Transparency Act, every director and PSC must now verify their identity — non-residents usually do this through an Authorised Corporate Service Provider (a formation agent) via a biometric passport check.
What changes because you are resident in the United States
Being resident in the United States adds a home-country layer on top of the UK rules: how the capital leaves the United States, and what you must report there once you own the foreign company. It doesn't stop you — it just needs planning alongside the UK steps below.
the United States’s outbound-investment and reporting rules
The US has no exchange controls, so a US person can freely invest in and fund a foreign company. The complexity is tax: US citizens and residents are taxed on worldwide income and must report their foreign companies and accounts, with anti-deferral rules (Subpart F and GILTI) that can tax certain foreign profits before you take a dividend.
- A US person owning 10% or more of a foreign corporation generally files Form 5471; a foreign disregarded entity uses Form 8858.
- Foreign bank accounts over USD 10,000 need an FBAR (FinCEN 114), and FATCA Form 8938 may also apply.
- Foreign corporate profits can be taxed currently under GILTI/Subpart F.
Documents you will need
- A valid passport for identity verification of each director and PSC
- Residential and service addresses for each director/PSC
- A company name ending in ‘Limited’ or ‘Ltd’ and SIC activity codes
- Share structure (often one £1 ordinary share to start)
- A UK registered office address and a registered email address
Step-by-step formation process
- Choose Ltd or LLP and a name. Check availability at Companies House and pick SIC codes.
- Verify identity. Directors and PSCs verify via GOV.UK One Login or an Authorised Corporate Service Provider.
- Prepare details. Set the registered office, directors, shareholders/PSCs and share structure.
- File the IN01. The application is filed with Companies House; approval is usually 24–48 hours.
- Register for tax. Register for Corporation Tax; your UTR arrives by post at the registered office in 7–14 days.
How to send the initial capital
You can fund the company by wire with no US approval required. Document it as share capital or an intercompany loan and keep records — you will reference them in Form 5471 and your US return.
Opening a bank account
A UK company can be formed remotely, but banking is separate. High-street banks often prefer a UK-resident director or an in-person meeting; fintechs such as Wise Business, Revolut Business and Tide onboard non-residents more readily. Expect identity checks, proof of the registered office and a clear description of the business. Approval is not guaranteed.
Taxation in UK
Corporation Tax is 25% (a 19% small-profits rate applies below £50,000, with marginal relief up to £250,000). VAT registration is required once taxable turnover exceeds £90,000, and PAYE applies if you employ staff. The UK does not tax non-resident shareholders on the company’s profits directly, but dividends may be taxable where the shareholder lives.
Tax and reporting back in the United States
Separately from UK tax, the United States taxes you as a resident and expects the home-country reporting set out above (see “the United States’s outbound-investment and reporting rules”). The practical point is that owning the foreign company is not tax-neutral at home: build both sides into your annual filing calendar rather than treating the UK return as the whole picture.
Cross-border tax considerations
As a US person you're taxed on worldwide income and must report the UK company — typically Form 5471 — with GILTI/Subpart F potentially taxing its profits. The US–UK treaty and foreign tax credits relieve most double tax.
Annual compliance in UK
- Annual accounts filed with Companies House.
- Company Tax Return (CT600) filed with HMRC and any Corporation Tax paid.
- Confirmation statement at least once a year.
- Maintain the PSC register and keep identity verification current.
Ongoing obligations in the United States
Keep your the United States position current: refresh any foreign-asset or foreign-affiliate disclosures each year, report further investment or repatriation, and keep records tying your shareholding back to the funds that paid for it.
Cost
Look at four separate costs, not one headline number:
- Government cost. The Companies House digital incorporation fee is £50–100, plus your registered-office and identity-verification service (formation-agent packages commonly run £100–300).
- Required third-party cost. Any mandatory local role — registered agent/office, company secretary, resident/nominee director or free-zone desk, depending on the country.
- StartEase professional fee. Quoted separately and clearly, so you see exactly what you pay us versus the government.
- Annual recurring cost. Renewals, accounting, tax filings and any local-role fees — ask “what will this company cost me to keep alive after year one?”
Timeline
Treat each regulator and the bank as a separate track — never bundle them into one “ready in X days” promise:
- Company incorporation: Usually 24–48 hours once identity checks are done
- UTR (tax reference): Posted to the registered office within about 7–14 days
- Bank account: A separate process — see below
Visa and immigration
Registering a UK company does not grant a visa or the right to live or work in the UK. Immigration routes such as the Innovator Founder visa are separate and have their own eligibility, endorsement and investment requirements.
Common mistakes to avoid
- On the the United States side: missing Form 5471 or FBAR reporting on the foreign company and its bank accounts.
- On the UK side: missing the annual confirmation statement, or not completing the new identity-verification step.
- Assuming ownership grants a visa or residency — it does not.
- Promising clients a live bank account on day one — onboarding is separate and can be declined.
- Choosing a heavier structure for prestige when a simpler one would cost far less to run.
Who this suits — and who it does not
It suits you if you have a genuine UK reason — customers, currency, market access or investors there. It may not suit you if your customers and operations are entirely in the United States with no real UK nexus, in which case the extra filings and cross-border reporting add cost without a clear benefit.
