How to Lose US Citizenship: Renunciation, Intent, and Exit Tax

To lose US citizenship, you appear in person at a US embassy or consulate abroad, sign an oath of renunciation before a consular officer, and pay a processing fee; the State Department then reviews your case and, if approved, issues a Certificate of Loss of Nationality. Roughly 5,000 people went through the process in 2024. Federal law recognizes a handful of other acts that can end citizenship, but formal renunciation is the cleanest route and the one the State Department calls the “most unequivocal” way to demonstrate intent to give up nationality.¹ Whatever the path, the consequences are permanent and reach into taxes, travel, and daily legal status.

How Formal Renunciation Works

Renunciation is governed by INA Section 349(a)(5). You schedule an appointment at a US diplomatic post abroad, attend an interview, complete a set of State Department forms, and take the oath. The core forms are the DS-4080 (the oath itself), the DS-4081 (your written acknowledgment that you understand the consequences of losing citizenship), and the DS-4083, which becomes your Certificate of Loss of Nationality. You may bring a private attorney or interpreter at your own expense.²

As of April 13, 2026, the processing fee dropped from $2,350 to $450. It is non-refundable, non-waivable, and paid immediately before the oath. If the Department later denies your Certificate of Loss of Nationality, the money does not come back.³

Renunciation generally cannot happen on US soil. INA 349(a)(6) allows a narrow wartime exception, requiring the Attorney General’s approval and a finding that the renunciation is not contrary to national defense interests. Outside that scenario, you have to be physically present in a foreign country at a US diplomatic post.⁴

One more constraint: you cannot renounce citizenship while claiming a right to keep living in the United States as a citizen. The State Department and the Supreme Court have both concluded that the required intent is missing in that situation. If you plan to remain in the US after renouncing, you must show that your future residence will be as a properly documented alien under immigration law.¹

Other Acts That Can End Your Citizenship

The Immigration and Nationality Act, at 8 U.S.C. § 1481, lists several “expatriating acts” besides formal renunciation. Any of them, performed voluntarily with the intent to give up citizenship, causes loss of nationality. Most require the person to be at least 18.⁴

Naturalizing in a foreign country through your own application or one filed on your behalf by an authorized agent.
Taking an oath or making a formal declaration of allegiance to a foreign state or political subdivision.
Serving in the armed forces of a foreign country if those forces are engaged in hostilities against the United States, or serving as a commissioned or noncommissioned officer in any foreign military.
Accepting employment with a foreign government when you already hold that country’s nationality or when the position requires a declaration of allegiance.
Being convicted of treason or attempting by force to overthrow the US government or bear arms against it.

A common misunderstanding: simply becoming a citizen of another country, or voting in a foreign election, does not automatically strip you of US nationality. The act has to be paired with specific intent to give up citizenship. Plenty of Americans hold dual nationality for decades with no effect on their US status.

Intent Is What Actually Ends Citizenship

For every expatriating act, intent separates a legally interesting fact from the loss of citizenship. Whoever claims the loss occurred carries the burden of proof, and the standard is preponderance of the evidence rather than the criminal beyond-a-reasonable-doubt standard.⁴

The State Department applies an administrative presumption that a US citizen who performs a potentially expatriating act intends to keep their citizenship. Evidence of a genuine intent to relinquish has to overcome that presumption. In practice, the Department will not strip citizenship from someone who naturalizes abroad, serves in a foreign military in a non-hostile capacity, or takes a foreign government job unless there is clear evidence the person wanted to stop being American.⁵

Formal renunciation under INA 349(a)(5) is different. Taking the oath before a consular officer is treated as an unequivocal statement of intent, and the oath itself essentially resolves the intent question. Voluntariness is still assessed, and the presumption of voluntariness can be rebutted on the facts of an individual case.⁵

Age Limits and the Six-Month Reversal

There is no hard statutory minimum age, but the State Department scrutinizes younger applicants closely. Children under 16 are presumed to lack the maturity and knowing intent needed to give up citizenship. Applicants between 16 and 18 get additional safeguards and careful review by both the consular post and Washington. Parents cannot renounce on behalf of a minor, and legal guardians cannot relinquish citizenship for someone who lacks mental capacity. A minor who renounces must independently show a consular officer that they are acting voluntarily, without undue parental influence, and that they understand the consequences. The Department recommends waiting until 18 unless circumstances are urgent.⁵

There is a safety net for young renunciants. Someone who takes the oath before turning 18 can have their citizenship reinstated by notifying the State Department within six months after their 18th birthday.⁵

When the Loss Becomes Official

Taking the oath does not, by itself, end your citizenship. The loss becomes official when the State Department approves and issues a Certificate of Loss of Nationality. After the interview, the consular officer prepares the certificate and forwards it to Washington for review. If approved, a copy goes to the former citizen and another to U.S. Citizenship and Immigration Services.²

Federal law also requires a copy to go to the IRS, which is what triggers the tax consequences below.⁶ Processing may take several months or longer after the interview, and during that waiting period you sit in legal limbo. Hold onto your US passport until the CLN is issued, since you may need it for travel in the interim.

The Exit Tax and Form 8854

The IRS does not simply stop taxing you on your expatriation date. Under IRC Section 877A, all property owned by a “covered expatriate” is treated as sold at fair market value the day before expatriation. Gain above an inflation-adjusted exclusion (set at $890,000 for 2025, with the 2026 figure expected to be slightly higher) is taxed as if you had actually sold everything.⁷

You become a covered expatriate if any one of three tests applies:

Your net worth is $2 million or more on the expatriation date.
Your average annual net income tax liability for the five preceding years exceeds the threshold ($206,000 for 2025, adjusted annually for inflation).
You fail to certify that you have complied with all federal tax obligations for the five years before expatriation.

⁸

That third test catches people. Even if your net worth is well under $2 million and your tax bills have been modest, missing returns or FBARs in prior years can make you a covered expatriate by default.

Every person who gives up US citizenship must file Form 8854 (Initial and Annual Expatriation Information Statement) with their tax return for the year that includes the expatriation date. If you would not otherwise have to file a return, you still need to send Form 8854 by the date the return would have been due. A $10,000 penalty applies for failing to file when required.⁸ The return itself is typically a dual-status return: resident for the portion of the year you were a citizen, nonresident alien for the rest.⁹

Coming Back as a Visitor

Once your CLN is approved, you are a foreign national. Visiting the United States means going through the same immigration process as anyone else from your country: either a visa (typically a B-1/B-2 visitor visa) or, if your new country of citizenship participates, the Visa Waiver Program. A visa does not guarantee entry; Customs and Border Protection officers at the port of entry make the final call on admission.¹⁰

There is a sharper consequence for former citizens the government believes renounced for tax reasons. Under the Reed Amendment at 8 U.S.C. § 1182(a)(10)(E), any former citizen the Attorney General determines to have renounced citizenship for the purpose of avoiding US taxation is inadmissible, meaning a permanent bar on entry.¹¹ Enforcement has been sparing, but the IRS’s automatic receipt of every approved CLN creates a paper trail. Covered-expatriate status alone does not trigger inadmissibility, though it raises the profile of a case.

The Risk of Statelessness

The State Department explicitly warns that unless you already hold a foreign nationality, renouncing US citizenship may leave you stateless. A stateless person has no government to issue them a passport, no automatic right to live or work anywhere, and no consular protection abroad. Practical fallout includes difficulty renting or buying property, inability to work legally, obstacles to marriage registration, loss of access to medical benefits, and restricted school access.⁵

The consular officer will discuss this during the process, and the DS-4081 requires you to acknowledge the consequences in writing. Even so, the Department will not refuse to process a renunciation solely because it would leave you stateless. If you insist, the government will let you proceed. Securing citizenship or permanent residency somewhere else before starting the renunciation is, for obvious reasons, the safer sequence.
