Yes, but the bank will ask more questions than it asks UK residents

A US citizen can open a UK bank account. Most high street banks — Barclays, HSBC, Lloyds, NatWest — will open accounts for American citizens who are physically present in the UK or who have a UK address. The process is straightforward if you have the right documents, but banks treat US citizens differently because of US tax law, not UK law. The extra scrutiny comes from FATCA (the Foreign Account Tax Compliance Act), which requires UK banks to report accounts held by US citizens to the Internal Revenue Service.

The practical result: you will need to prove your US citizenship and tax status, and the bank will ask you to confirm you understand your US tax obligations. Some banks have stopped serving US customers altogether because the compliance cost is high. Others have made it routine. Your chances are best with banks that have a US presence or that already serve many American expats.

Key Takeaways

  • UK banks can open accounts for US citizens, but most require you to be in the UK in person or have a UK address to start the process.
  • You will need a valid US passport, proof of your UK address (a utility bill or tenancy agreement), and sometimes proof of income or employment.
  • Banks must report your account to the IRS under FATCA, and they will ask you to confirm you understand your US tax filing obligations.
  • Some banks have closed to US customers; HSBC and Barclays remain open to Americans, but policies change and vary by branch.
  • Opening an account takes one to four weeks after your in-person appointment, because the bank must complete FATCA verification before activating the account.

What documents you need to bring

Bring your valid US passport — this is the document the bank will use to verify your citizenship and identity. A UK driving licence or national ID card alone will not be enough; the bank needs proof of US citizenship specifically.

Bring proof of your UK address. A utility bill (gas, electricity, water), a council tax bill, or a tenancy agreement all work. The bill or letter must show your name and the address where you want the account registered. If you have just moved, a letter from your landlord or a recent tenancy agreement is acceptable. Post Office verification services can also provide a letter if you cannot get a utility bill quickly.

Bring proof of income or employment if the bank asks. This might be a recent payslip, a letter from your employer on headed paper, or a contract. Some banks ask for this; others do not. Call ahead and ask what the specific branch requires.

Which banks are currently open to US citizens

HSBC and Barclays both have explicit processes for opening accounts for US citizens. Both have US operations, which means they already have FATCA compliance systems in place. HSBC is often the easier route because it has a dedicated expat banking service and branches in major cities. Barclays will open accounts but the process is slower and varies by branch.

Lloyds, NatWest, and Santander have closed or severely restricted accounts for US citizens in recent years. This changes; call your local branch to ask their current policy rather than assuming it is closed. Some smaller building societies and challenger banks (Wise, Revolut) have different rules — Wise, for instance, is designed for people who move between countries and has simpler US citizen onboarding.

Do not assume a bank's website tells you the current truth. Call the branch where you want to open the account and ask directly: "I am a US citizen. Can I open a current account?" This takes five minutes and saves you a wasted trip.

What happens during the in-person appointment

You will sit with a bank representative who will photocopy your passport and UK address proof. They will ask you to complete a form confirming your US tax residency status — specifically, whether you are a US citizen or US resident alien for tax purposes. This is the FATCA declaration. You will sign it. The bank will explain that they are required to report your account details to the IRS.

The representative may ask about the source of funds you plan to deposit and the purpose of the account. This is standard anti-money-laundering procedure, not specific to US citizens, but the bank will document your answers. Be straightforward: "I work here" or "I am a student" or "I am transferring savings from the US" are all normal answers.

You will choose the type of account — usually a current account (what Americans call a checking account) with a debit card. You may be offered a savings account as well. The bank will tell you when your account will be active. This is not the same as when you leave the branch. The bank must complete FATCA verification in the background, which takes one to four weeks. You will receive a letter or email when the account is ready to use.

How long the process takes and what happens next

The in-person appointment takes 30 to 45 minutes. You will leave with a temporary card or a promise that a card will arrive by post. The account itself will not be usable for transfers or payments until FATCA verification is complete. This delay is not a mistake; it is the bank waiting for confirmation from their compliance team that your US tax status has been properly recorded.

Once the account is active, you can deposit money, set up standing orders, and use your debit card like any other UK bank customer. You will receive statements by post or online, depending on your preference. The bank will send you a letter each year confirming that they have reported your account to the IRS — this is normal and expected.

Your US tax obligations do not change

Opening a UK bank account does not change what you owe the IRS. If you are a US citizen, you must file a US tax return every year, even if you live in the UK and earn only UK income. You may owe US tax, or you may not — that depends on your income and whether you claim the Foreign Earned Income Exclusion — but you must file.

You must also report the account to the US Treasury if the balance ever exceeds $10,000 at any point during the year. This is done on Form FinCEN 114 (formerly called the FBAR), filed with the Financial Crimes Enforcement Network. The important date is April 15 (or October 15 if you file an extension). Your UK bank will not do this for you; you must do it yourself or hire a tax professional who understands US expat tax law.

The bank's FATCA report to the IRS is separate from your FBAR filing. Both happen, and both are required. This is one reason some banks have stopped serving US customers — the compliance burden is real, and mistakes can be expensive.

Alternatives if a UK bank will not open an account for you

If you cannot open a traditional UK bank account, Wise (formerly TransferWise) offers a multi-currency account that works for US citizens in the UK. You can hold money in GBP, USD, and other currencies, and you receive a debit card. Wise is designed for people who move between countries and has streamlined FATCA compliance. The account is not a full UK bank account — you cannot overdraft, and some services are limited — but it works for everyday spending and transfers.

Revolut also serves US citizens, though their policy has changed several times. Check their current terms before you explore.

If you need a traditional bank account and cannot open one, you may need to wait. Some banks periodically reopen to US customers, or you may find a smaller building society willing to take you on. Persistence and calling multiple branches sometimes works.

Frequently Asked Questions

Do I need to be a UK resident to open a UK bank account as a US citizen?

Most banks require you to be physically present in the UK and have a UK address. Some banks will open accounts for people who are moving to the UK if you can provide a tenancy agreement or letter from your employer showing your future UK address. Call the bank and ask about their specific policy.

Will the bank report my account to the US government?

Yes. Under FATCA, UK banks must report accounts held by US citizens to the IRS. The bank will tell you this during your appointment and ask you to sign a form confirming you understand. This is not optional and does not mean you have done anything wrong.

Can I open a UK bank account if I am a green card holder but not a US citizen?

Yes. Green card holders are treated as US residents for tax purposes and are subject to the same FATCA reporting requirements. Bring your green card instead of a passport, along with the same address and income documents a US citizen would need.

What if I already have a UK bank account and the bank finds out I am a US citizen?

The bank may ask you to complete a FATCA declaration retroactively. Some banks have closed accounts when they discovered the holder was a US citizen, but this is rare. More commonly, they will ask you to sign the FATCA form and then continue serving you normally. If the bank does close your account, you will have time to move your money — they will not freeze it when ready.

Can I use my US address instead of a UK address to open an account?

No. UK banks require a UK address for the account. If you are moving to the UK, provide your future UK address. If you are visiting temporarily, you cannot open a bank account — you would need to be resident or have a clear plan to become resident.
