For entrepreneurs in the United Kingdom and across the European Union, establishing a company in the United States can open the door to a vast market and new business opportunities. One question that comes up consistently during the formation process is whether you need an American address to operate a US company.
The answer is nuanced. You do not need to live in the United States or maintain a physical office there, but most US companies do require at least one form of US-based address for legal and administrative purposes. Understanding the different types of addresses involved — and what each one actually does — helps founders avoid compliance gaps and unnecessary costs.
This article explains the role of a US address in company formation, the difference between a registered address and a trading address, and the practical options available to non-resident founders.
The Three Types of US Address
When setting up a US company, several different addresses may come into play — and they are frequently confused with one another. Each serves a distinct purpose, and not every company will need all of them.
Registered agent address: A legal requirement in every US state. This is where official government documents, legal notices, and compliance correspondence are received on behalf of the company. It must be a physical address in the state of formation — P.O. boxes are not accepted. This address is typically not used for any commercial purpose.
Business or mailing address: An optional but often useful additional US address used for general business correspondence, banking applications, and payment processor registrations. This can be a virtual office, a commercial mailbox service, or a coworking space address.
Trading or operational address: The location associated with the company's commercial activities. For a remotely operated LLC with no US presence, this may simply be your home office address in the UK or EU — or it may not apply at all if the business operates purely online.
The Registered Agent Address: The One You Cannot Skip
Every US LLC and corporation is legally required to appoint a registered agent with a physical address in the state of formation. The registered agent receives official government documents and legal notices on behalf of the company — including state compliance reminders, tax correspondence, and legal papers if the company is ever involved in litigation.
For foreign founders, this requirement is straightforward to satisfy. Professional registered agent services maintain a local address in each state, receive official mail on the company's behalf, and forward it digitally. The cost is typically modest — between $50 and $150 per year depending on the provider and state. We include registered agent service in our Wyoming LLC formation packages, so this is handled from day one.
It is important to understand that the registered agent address is not a public-facing business address. It is purely administrative and legal. Using it as your primary business address on invoices, websites, or banking applications is technically possible but not always advisable — some banks and payment platforms treat formation-state registered agent addresses with additional scrutiny.
Do You Need a Physical Office in the US?
No. Many UK and European founders run US LLCs entirely without a physical US presence. Software companies, consultants, digital agencies, content businesses, and e-commerce operators routinely serve US customers while being managed from Europe. As long as the company maintains a registered agent, meets its federal and state reporting obligations, and does not have employees or inventory physically based in the US, no office is required.
Where a physical presence does exist — employees on US soil, inventory in a US warehouse, or regular in-person operations — additional tax obligations arise. That presence creates "nexus" in the relevant state, which can trigger state income tax, franchise tax, and sales tax registration requirements. For founders operating remotely with no US footprint, nexus is generally not a concern, but it is worth confirming with a tax adviser if your situation is at all ambiguous.
Virtual Offices and Mail Forwarding
For founders who want a US business address beyond the registered agent's office — for banking, client credibility, or general correspondence — virtual office services and mail forwarding providers are the most common solution.
Virtual office services provide a legitimate commercial US address (typically in a major city or business district), mail handling, and often optional add-ons such as telephone answering and on-demand meeting room access. The address can be used on invoices, websites, and banking applications. Providers include Regus, WeWork (virtual plans), Alliance Virtual Offices, and Intelligent Office, among others.
Mail forwarding services focus on receiving physical mail at a US address and scanning or forwarding it to the founder abroad. They are typically lower cost than full virtual office packages and sufficient for founders whose primary need is occasional physical correspondence rather than a credible business address.
When choosing between these options, the most important factor is whether the address will be accepted by your target bank or payment processor. Some fintech platforms are straightforward; traditional US banks may have stricter views. Checking in advance saves time.
US Address Requirements for Banking
Opening a US business bank account is where the address question becomes most practically significant. Traditional US banks typically require a US business address and often ask owners to appear in person — both of which create barriers for non-resident founders. Fintech platforms have changed this substantially, but address requirements still vary.
Mercury, the most widely used banking platform for remote-owned LLCs, accepts non-US residential addresses for beneficial owners and does not require a US business address in all cases — though having one can smooth the compliance review. Relay and Wise Business have similar flexibility. For a full breakdown of what each platform requires, see our banking documents checklist.
If you are using a virtual office address for banking purposes, ensure the address is from a reputable commercial provider. Residential-looking addresses or addresses shared by thousands of companies on a formation agent's database can sometimes trigger additional scrutiny from bank compliance teams.
Address Requirements for the IRS and EIN Application
When applying for an Employer Identification Number (EIN) from the IRS, the company must provide a mailing address for official correspondence. This does not need to be a physical US office — the registered agent address, a virtual office address, or even your home address in the UK or EU can be used depending on how the application is structured.
Non-resident founders applying for an EIN by fax or through an Enrolled Agent typically use the business's formation-state address or the registered agent's address for IRS correspondence, then arrange separate mail forwarding for any physical documents the IRS sends. Our Enrolled Agent Richard Williams handles EIN applications directly and advises on the most appropriate address to use for your specific situation.
What Address to Use Where: A Practical Summary
- State formation documents: Registered agent address (mandatory, provided by your agent)
- IRS EIN application: Registered agent address or a US mailing address — your home address abroad is also accepted in most cases
- Business bank account: US mailing or virtual office address preferred; some platforms accept non-US addresses for the beneficial owner
- Stripe / PayPal / payment processors: US business address typically required; registered agent or virtual office address works
- Invoices and website: Your choice — many remote founders use their UK or EU address; others use a US virtual office address for market credibility
- FinCEN BOI report: Your current residential address abroad — a US address is not required for non-resident beneficial owners
The Bottom Line
UK and EU founders do not need to live in the United States or rent an American office to operate a US LLC. Every company must appoint a registered agent with a state address — this is the one non-negotiable US address requirement — but beyond that, additional address arrangements depend on your banking platform, payment processors, and how you want to present the business to US clients.
For most non-resident founders running online or service-based businesses, the registered agent address plus a reputable virtual office address covers every practical need. With the right setup in place, the address question is one of the simpler aspects of running a US company from Europe.
We help UK and European founders navigate every step of US LLC formation — from state selection and registered agent appointment to EIN applications and banking guidance. Our Enrolled Agent Richard Williams is also available to advise on the tax implications of your specific business structure.
