The £97k Lesson: Renounce Early—or Pay the IRS
Ben & Liza, dual UK–US citizens, sold their UK home to retire—then lost £97k to a surprise IRS capital gains bill; renouncing a year earlier could have avoided it.
WHY ARE SO MANY GIVING UP THEIR U.S. CITIZENSHIP?
DOUBLE TAXATION
Tax treaties can help with double taxation, but they don’t cover everything. Selling your home in the UK, Australia, and many other countries can carry a large US capital gains tax bill with it.
Fee Reduction
The fee to renounce US citizenship was US$450 before 2014, when it increased to US$2,350. It has now returned to US$450 following a reduction by the US Department of State.
FINANCIAL FREEDOM
Investing for your future outside of the US can be an expensive ordeal due to heavy restrictions, tax compliance costs and additional taxes.
ACCIDENTAL AMERICAN
Little or no connection to the United States comes with a heavy tax burden, which to many, is reason enough to renounce their citizenship.
How do I renounce my US citizenship in the UK?
Initially, schedule an appointment with a US Embassy or Consulate. During this appointment, you will complete several forms, including the DS-4079 (Request for Determination of Possible Loss of United States Citizenship) and DS-4080 (Oath of Renunciation of the Nationality of the United States).
To book an appointment in the UK, use this embassy link.
You can renounce at the US embassy in London or the US consulate in Belfast.
The US consulate in Edinburgh does not accept appointments for citizenship renunciation.
What does renouncing U.S. citizenship entail?
Renouncing US citizenship means formally relinquishing your nationality through a legal process. This decision is irreversible; some common motivations include avoiding complex US tax obligations, political disagreements, or wanting to integrate fully into life in another country.
Who is eligible to renounce U.S. citizenship?
You must be an adult with citizenship in another country and be up-to-date on U.S. taxes. It’s essential to understand the consequences of your decision entirely.
You should already possess citizenship in another country, as the U.S. government aims to prevent statelessness. Holding another citizenship before renouncing your U.S. citizenship ensures you have the legal rights and protections of a citizen in another country.
Renouncing your U.S. citizenship is a complex and irreversible process. It’s essential to understand the legal and tax implications thoroughly. Consulting with a tax professional or legal advisor specializing in citizenship can provide personalized guidance and help navigate this significant decision.

What are the steps to legally renounce U.S. citizenship from the UK?
- Schedule an Appointment: Contact the London U.S. Embassy or Belfast Consulate to schedule an appointment for renunciation.
- Complete Necessary Forms:
- Fill out Form DS-4079 (Request for Determination of Possible Loss of United States Citizenship).
- Complete Form DS-4080 (Oath of Renunciation of the Nationality of the United States).
- Don’t sign the forms until you’re in the presence of an officer during your interview.
- Attend the Interview:
- Go to your scheduled interview at the U.S. Embassy or Consulate.
- Discuss your reasons for renouncing citizenship and understand the consequences with a consular officer.
-
Pay the Renunciation Fee: A fee must be paid during the interview to process your renunciation. The fee is US$450, following the US Department of State’s implemented reduction.
- Take the Oath of Renunciation:
- Formally renounce your citizenship by taking the Oath of Renunciation.
- This step is irreversible, so ensure you are fully committed to this decision.

- Get specific US tax advice to check if you’re a covered or non-covered expatriate.
- File your final dual-status tax return (Form 8854) with the IRS.

Do I have to file my US taxes before renouncing?
No, but it’s a good idea to start your US tax compliance journey while waiting for your embassy appointment. Gathering all the documents and statements to prepare multiple years of US tax returns can take time.
It’s highly advisable to speak with a US renunciation specialist, so you’re fully aware of your US tax situation.
What are the financial implications of renouncing US citizenship?
The financial implications primarily involve tax obligations and the potential imposition of an Exit Tax. Here’s a more detailed look at what this entails:
- Up-to-date Tax Obligations: There are two parts to giving up US citizenship. The first is to attend a renunciation interview at a US embassy or consulate, as discussed. The second is to exit the US tax system. You must ensure all your tax affairs are in order. This includes filing your final tax return and settling any outstanding taxes with the IRS.
- You’ll need to have your last five years of tax returns filed with the IRS in addition to the year you renounce.
- Complying with all tax obligations is crucial to safely exiting the US tax system, without delay or penalty.
Why do I have to file US taxes when I live in the UK?
The United States requires you by law to file a US tax return each year, regardless of where you live. The US tax system is based on citizenship, not residency—meaning you must report your worldwide income even if you’re living abroad.
The fact that the US follows a citizenship-based taxation system often leads to confusion for expats who are used to the residency-based systems of other countries.
Do I need to be tax compliant to renounce my citizenship in the UK?
Yes. However, to renounce your US citizenship while living in the UK, you need to complete a two-step process. First, you must schedule an interview with the US Consulate. Second, you need to ensure you’re tax compliant, which involves specific steps to inform the IRS that you’ve given up your citizenship.
What is exit tax and who pays it?
Exit tax is a tax imposed on US citizens or long-term residents classified as “covered expatriates” when they choose to renounce their US citizenship or give up their Green Card.
But not every US expatriate is subject to this tax; only those who meet specific criteria are considered covered expatriates.
These criteria include meeting one of three tests: a net worth test, an average annual net income tax test, or a failure to certify compliance with US tax obligations for the five years before expatriation.
