How to Register a US Company from the UK in 10 Minutes

Bryce Warnesby Bryce Warnes • 7 min readpublished August 13, 2021

Thinking about starting a US company from UK?

So you’re a startup founder in England, Scotland, Wales, or Northern Ireland. You’d like to register a US company from the UK, where you’re a resident. Must be complicated, right?

Not so. For residents of the UK, incorporating a company follows the same process as it does for US residents.

However, the process differs according to whether or not you have already formed a limited company locally. In order to avoid a legal or financial tangle, you must be sure to cross all your i’s and dot all your t’s.

This article covers:

  • The reasons UK companies incorporate in the US
  • The process of incorporating in the US as a UK founder
  • How to get a registered agent for your US corporation
  • How to perform the “Delaware flip,” transferring your UK company’s registration to the US
  • Everything UK founders incorporating in the US need to know about taxes, work visas, and hiring

Why register a US company from the UK?

One of the primary reasons to register a US company from the UK is access to capital.

UK startups raised a total of $16.6 million USD (€14 billion) in venture capital in 2020. Contrast that with $130 billion USD (€109 billion) raised in the US that same year.

Overall, there is a much larger startup ecosystem in the US, and many more opportunities for funding. US investors often prefer that UK companies incorporate in the US. A corporation able to offer US equity to American employees has a bigger talent pool to draw upon. (Equity in US corporations offers tax advantages to US employees that UK corporate equity does not.)

Tax rate also partly plays a role. Six or seven years ago, some investors were willing to fund UK registered companies—at 35%, the US corporate tax rate at the time did not offer a competitive advantage compared to the UK’s. Since then, the US corporate tax rate has dropped back down to 21%, regaining its edge and making US corporations more attractive to investors once again.

Most importantly, corporations formed in the US have to deal with less bureaucracy overall. And the Delaware courts, particularly, are known for their efficiency when it comes to corporate legal proceedings.

How should a UK founder incorporate their company in the USA?

In order to register your company in the UK, you must follow six steps:

  1. Pick the right entity type for your business. Since most investors prefer C corporations, most founders choose this type of company.
  2. Choose a state in which to register your company. The vast, vast majority of US tech companies are incorporated in Delaware—as are 70% of Fortune 1000 companies.
  3. File articles of incorporation. Capbase makes this easy for you; filing articles of incorporation takes minutes, and the cost of doing so is incorporated in our flat fee.
  4. Obtain an employer identification number (EIN) from the Internal Revenue Service (IRS). You require an EIN to open a US bank account. And getting an EIN sets you up to pay taxes in the US. (Capbase registers an EIN on your behalf.)
  5. Open a bank account in the US. A US bank account is essential for doing business in the US. Once you receive your EIN, you’re able to open one.
  6. Keep in good standing by filing reports. To maintain good standing with tax authorities, your company must file reports every year. March 1st is the filing deadline. Built in Capbase tools can help you track and manage compliance requirements.

What is a registered agent, and how do I hire one?

You don’t need to live inside the US to register a US corporation, but you do need a registered agent.

Your registered agent’s job is to receive federal and state communications, tax notice from the IRS and local authorities, notices of subpoenas, and other official mail on your behalf. They have a physical address in the state where you incorporated, at which they can receive:

  • Compliance notices regarding reporting and other requirements
  • Tax documents from Delaware’s revenue or tax departments
  • Services of process (ie. any lawsuits against your company)

Keep in mind, you don’t use your registered agent’s address as your legal address. Your legal address must be your own business address in the UK. You’ll use your business address for:

  • Opening business bank accounts
  • Sending and receiving invoices
  • Filing for legal contracts, permits, or licenses

When you sign up with Capbase and register your company in Delaware, Capbase serves as your registered agent for your startup.

How do you register your company in the US if it’s registered in the UK? (The Delaware Flip)

If your company is already a UK limited company, you can use an approach called the “Delaware Flip” to effectively move it to the US.

This is easiest to do when your company is still young, with few shareholders and outside investors.

In essence, you file articles of incorporation for a Delaware C corp, then acquire your UK company and make it a subsidiary.

Step by step:

  1. Hire UK accountants and lawyers to ensure you have all the necessary regulatory approvals to convert your company. You’ll also need to pay off all debt and outstanding equity.
  2. Register a Delaware corporation. This requires you to name officers and directors, and allocate shares. (Using Capbase, you can file your articles of incorporation in about 10 minutes.)
  3. The shareholders in your UK limited company agree to contribute all shares, cash, and intellectual property in the UK company to the new US corporation, making the UK company a subsidiary. This requires a share repurchase (buyback); you may wish to use a clearance letter so your shareholders can avoid paying Income Tax on the payment they receive from you.

After this, the final step is for your new US-registered corporation to acquire your UK company as a subsidiary.

What about US taxes and visas for UK business owners?

When you register your company in the US, your personal tax residency doesn’t change. You still pay UK taxes on your personal income, while your US corporation is taxed in the US.

You don’t need a visa to do business in the US. Thanks to the US Visa Waiver Program, you can spent up to 90 days in the US conducting business.

But, if you plan on spending more than 90 days working in the US, you’ll need a Visa. We cover this matter—including information on E-1, E-2, EB-5, L-1, and O-1 visas—with our complete guide to US immigration visas for startup founders.

Hiring UK employees with your US corporation

Once you’ve started your Delaware C corporation, you aren’t limited to hiring US citizens. You can hire employees locally, in the UK—but you’ll need to follow a few extra steps.

To hire UK employees, you have one of two options:

  1. Start a UK business to hire local workers, and make it a subsidiary of your Delaware corporation.
  2. Set up a remote payroll & compliance service like Deel or Both of these services let you hire employees abroad either as full-time employees or international contractors. In the former case, Deel or Remote act as the employer-of-record (EOR) for the employees and hire them on behalf of your company.

Heads up: Capbase users get 30% of their first year using Deel.

  • When you form a US corporation, you get access to a capital market much larger than the one in the UK. And equity in a US corporation is good leverage for hiring US talent.
  • You don’t need a US address to form a US company from the UK, but you do need to hire a registered agent to represent you in the state where you incorporate.
  • Your UK tax status stays the same even if your company is formed in the US. (Your corporation will have to pay US taxes, however.)
  • To hire UK talent, you’ll either need to form a UK subsidiary of your new US corporation, or use an international payroll & compliance service like Deel or Remote.
