The cost to renounce US citizenship in Spain has just dropped from $2,350 to $450 — an 80% reduction that takes effect on April 13, 2026, after the U.S. State Department published the final rule in the Federal Register on March 13, 2026. For Americans living in Spain who have been weighing this step, the new fee removes one of the most-cited financial barriers to filing a Certificate of Loss of Nationality. By the end of this guide you will know what changed, how the renunciation process works at U.S. consulates serving Spain, what tax compliance is required before you renounce, and how Spain’s separate “renunciation” of other citizenships during naturalization differs from the formal U.S. process. Let’s start with what actually changed.
What Changed: The U.S. Cuts the Fee to Renounce US Citizenship
The U.S. Department of State has reduced the fee for processing a request for a Certificate of Loss of Nationality (CLN) from $2,350 to $450, an 80% cut. The final rule was published in the Federal Register on March 13, 2026 and takes effect 30 days later, on April 13, 2026.

The State Department justified the reduction as a way to ease the cost burden on people seeking to renounce US citizenship and to better align the fee with similar consular services. The previous $2,350 fee had been criticized for years as one of the highest renunciation fees in the world.
Why the Fee Cut Matters for Americans in Spain
For Americans in Spain — including long-term residents, dual nationals, accidental Americans, and people considering Spanish naturalization — the fee cut removes a meaningful financial barrier. Filing a CLN is the only way the U.S. government formally recognizes a loss of U.S. citizenship; nothing Spain does on its own (such as a verbal “renunciation” during naturalization) is enough on the U.S. side.
The lower fee should make the process more accessible to:
- Long-term U.S. expats who have built their lives in Spain and never plan to return to the United States
- Accidental Americans — people born in the U.S. who left as children and only later discovered the U.S. considers them citizens
- Dual nationals who have completed Spanish naturalization and want to formalize the U.S. side as well
- Tax-burdened expats who file U.S. returns every year solely because of citizenship-based taxation

Renouncing U.S. citizenship is a formal legal act, not paperwork you file by mail. The process to renounce US citizenship requires:
- An in-person appointment at a U.S. embassy or consulate. For Americans in Spain, this means the U.S. Embassy in Madrid or the U.S. Consulate General in Barcelona.
- Two interviews in many cases — an initial consular meeting and a second appointment to take the formal Oath of Renunciation.
- Forms DS-4079, DS-4080, and DS-4081 (questionnaire, oath of renunciation, and statement of understanding).
- Payment of the $450 fee (from April 13, 2026 onward).
- Clear demonstration of voluntary intent to give up U.S. nationality. The consular officer must be satisfied the act is voluntary and informed.
After the oath is taken, the consulate forwards the file to the State Department in Washington, which formally issues the Certificate of Loss of Nationality. From the date of the oath, U.S. citizenship is considered terminated for U.S. legal purposes — although the CLN itself can take several months to arrive.
Tax Compliance Before You Renounce US Citizenship
The fee is only one part of the cost picture. Anyone planning to renounce US citizenship should also plan for the tax side, which can be far more financially significant than the consular fee.
Key tax considerations include:
- Five years of U.S. tax compliance. The U.S. expects renouncing citizens to certify they have filed all required federal returns for the five tax years preceding the renunciation. Failing this certification can have major consequences under the “covered expatriate” rules.
- The Exit Tax (Section 877A). If your net worth exceeds $2 million, your average annual U.S. income tax liability over the past five years exceeds a threshold (around $206,000 in 2025), or you fail the five-year compliance certification, you may be classified as a “covered expatriate” and owe an exit tax on unrealized gains.
- Form 8854. The Initial and Annual Expatriation Statement must be filed with your final U.S. tax return.
- Spanish tax residency. Once you renounce U.S. citizenship and remain a Spanish tax resident, your worldwide income and reporting obligations move entirely under Spanish rules. See Spainguru’s guide to taxes for expats in Spain for current rates and structures.
For most people considering renunciation, the right next step is a consultation with a cross-border tax advisor experienced in U.S.-Spain matters before booking the consular appointment.
Spain’s “Renunciation” During Naturalization vs the U.S. Process
Spain’s naturalization process requires applicants from most countries — including the United States — to verbally declare that they renounce their previous citizenship. This declaration is symbolic on the Spanish side; it does not actually trigger any process to terminate U.S. citizenship in the eyes of the U.S. government.
For a detailed explanation of how this works in practice, see Spainguru’s coverage of the question whether it is a requirement to renounce U.S. citizenship to apply for Spanish citizenship and the related guide on the process of telling Spain you renounce all other citizenships.
The practical result: many Americans who naturalize in Spain remain U.S. citizens in the eyes of Washington. They keep their U.S. passport, continue to file U.S. tax returns under citizenship-based taxation, and only formally lose U.S. nationality if and when they personally choose to file a CLN at a U.S. consulate.
Timing: Before or After April 13, 2026?
The new $450 fee applies to renunciation appointments held on or after April 13, 2026. Anyone with an appointment scheduled before that date will still be charged the old $2,350 fee, unless the consulate offers to reschedule.
If you are at the very early stage of considering this step, the timing question is straightforward: wait until on or after April 13, 2026 to take the oath. If you have already booked an appointment for late March or early April 2026, contact the embassy or consulate directly to ask whether rescheduling is possible.
If you have already paid the higher fee at an earlier appointment, the new rule does not appear to provide a refund pathway. Confirm directly with the relevant U.S. embassy or consulate.
Frequently Asked Questions
How much does it cost to renounce US citizenship in Spain after April 13, 2026?
$450 in U.S. consular fees, payable at the appointment when you take the Oath of Renunciation. This is in addition to any tax-related costs (advisor fees, exit tax if applicable, final-year filings) and the cost of obtaining the supporting documentation.
Where do I renounce US citizenship if I live in Spain?
At the U.S. Embassy in Madrid or the U.S. Consulate General in Barcelona. You cannot renounce by mail or via a notary. The Oath of Renunciation must be administered in person by a U.S. consular officer. Appointment availability varies — book several months in advance when possible.
Does naturalizing in Spain mean I automatically lose U.S. citizenship?
No. The verbal renunciation declaration that Spain requires during naturalization is not legally binding under U.S. law. Most Americans who naturalize in Spain remain U.S. citizens until they personally renounce US citizenship through the formal U.S. consular process.
Do I need to be tax compliant before I renounce?
Yes — strongly recommended. The U.S. expects renouncing citizens to certify five years of tax-return compliance. Falling short can trigger the “covered expatriate” classification and the exit tax. Speak with a cross-border tax advisor before booking the appointment.
Is there an exit tax when I renounce US citizenship?
Possibly, depending on your wealth, income history, and tax-compliance status. Covered expatriates owe a one-time tax on unrealized gains above an exemption threshold. Consult an experienced U.S.-Spain tax advisor to model your specific situation.
Can I keep my Spanish citizenship after I renounce US citizenship?
Yes. Renouncing U.S. citizenship has no automatic effect on your Spanish nationality. Spain treats your nationality status separately from any U.S. consular action.

Conclusion: Renounce US Citizenship in Spain — A Cheaper but Still Serious Step
The fee cut from $2,350 to $450 is the biggest financial change to U.S. renunciation in more than a decade. For Americans in Spain who have already mentally crossed the line and are simply waiting for the right moment, April 13, 2026 is that moment.
That said, the consular fee was never the main reason renunciation is hard. Tax compliance, the exit-tax exposure, the irrevocability of the act, and the loss of U.S. consular protection abroad all weigh more heavily. Approach the decision with a cross-border tax advisor, an immigration lawyer if your residency setup is complex, and time to think through what you are giving up.
If you are confident this is the right step, the lower fee makes 2026 the most affordable year in over a decade to renounce US citizenship from Spain.
