Concept
Renunciation of citizenship may seem like the final step in any flag theory strategy, but in practice it is a narrow door with two locks. The first lock is international law, which prohibits rendering a person stateless. The second is tax-related: countries like the United States charge an exit tax for renunciation. Before surrendering a passport, it is worth understanding both mechanisms and their sequence.
Prohibition on Statelessness
International law proceeds from the principle that every person should have at least one citizenship. The 1961 UN Convention on the Reduction of Statelessness explicitly requires that renunciation take effect only when a person already has or is guaranteed to obtain another citizenship. Therefore, most states will not accept an application for renunciation until the applicant presents a second passport. First a second citizenship, and only then renunciation of the first—this order protects against the status of statelessness, in which a person loses the right to enter anywhere, to work legally, and to consular protection.
Exception: The US Permits Exit into Statelessness
The United States stands apart in this regard. Formally, a US citizen may renounce citizenship even without having another, thereby becoming stateless. The State Department insistently warns of the consequences of such a step, requires personal appearance at a consulate, and an oath of renunciation. In practice, exit into statelessness is almost never justified: a stateless person retains prior tax obligations but loses the basic rights that a passport provides.
Covered Expatriate and Exit Tax
For Americans, exit hinges on tax. A person is considered a covered expatriate if at least one condition is met: net assets of $2 million USD or more, average annual income tax for the five preceding years above $206,000 USD by the 2025 threshold, or inability to confirm on Form 8854 full compliance with tax obligations for five years. A covered expatriate is subject to exit tax under the mark-to-market rule: all assets are deemed sold at fair market value on the day before exit, and the resulting gain is taxed. For 2025, the first $890,000 USD of this gain is excluded.
⚙️ The fee for renouncing US citizenship long stood at $2,350 USD and was one of the highest in the world. As of April 2026, the State Department reduced it to $450 USD. But for a wealthy individual, the real cost of exit consists of the exit tax and the obligation to close all tax liabilities for five years, while the fee itself is secondary against this backdrop.

The logic for anyone considering renunciation is the same. First, secure a reliable second citizenship. Then bring tax history into order, since unresolved obligations automatically confer covered expatriate status. And only after that, apply for exit. For US citizens, the exit tax is calculated separately, while for citizens of other countries the rules of their own legislation on exit and possible readmission to citizenship come to the fore.
🍓 Renunciation of citizenship works only when a second passport is already in hand: international law does not permit becoming stateless, and most countries will not accept an application without proof of another nationality. For Americans, the exit tax is added: covered expatriate status arises with assets of $2 million USD or more or average tax above $206,000 USD for five years, and for 2025 the first $890,000 USD of deemed gain is excluded.
