Building a life overseas can bring questions that go far beyond visas, accommodation, and flights. For Americans settling abroad permanently, those questions sometimes include whether to retain U.S. citizenship.

Recent expatriation figures have brought that decision into sharper focus. An analysis by Greenback Expat Tax Services found that 5,790 names appeared in the four quarterly Treasury notices covering July 2025 through June 2026—the highest rolling four-quarter total since 2020.

The second quarter of 2026 accounted for 1,781 names, up 68.5% from the same period in 2025. Across the first half of 2026, the total reached 3,243, up 38.5% year over year. Greenback’s analysis

These figures need careful interpretation. The notices include both former citizens and certain long-term green card holders ending their U.S. tax residency. The publication date reflects when Treasury received the information, which may be later than the actual change in status. They therefore cannot establish how many Americans moved overseas during those months or exactly when people renounced citizenship.

For travel readers, that distinction matters: relocating abroad and giving up citizenship are separate decisions.

Why overseas tax obligations matter

American citizens generally remain subject to U.S. tax rules on worldwide income while living overseas. Depending on their circumstances, they may need to file U.S. returns alongside paperwork required in their country of residence. IRS guidance for Americans abroad

However, this does not automatically mean paying full income tax twice. Eligible taxpayers can use provisions such as the foreign tax credit and foreign earned income exclusion to reduce or sometimes eliminate their U.S. income tax liability. Filing requirements can still apply even when no U.S. income tax is ultimately due. IRS explanation of overseas filing and tax benefits

FATCA, the Foreign Account Tax Compliance Act, adds another layer of reporting. It generally requires foreign financial institutions to report information about relevant U.S. accounts, while certain taxpayers must disclose specified foreign financial assets. The law concerns reporting and compliance; it did not create citizenship-based taxation. IRS overview of FATCA

For someone whose work, family and finances are established abroad, managing these obligations can become part of a wider reassessment of citizenship. Still, the published name lists do not reveal individual motives or establish how much tax concerns, politics, or personal ties contributed to the increase.

A lower fee changes the cost.

The administrative price of renunciation fell substantially in 2026. Effective April 13, the State Department reduced the fee for processing a request for a Certificate of Loss of Nationality from $2,350 to $450—an approximately 81% reduction. Federal Register fee rule

That lowers one expense associated with the process. It does not establish that the fee change caused the latest increase, particularly because Treasury reporting can lag behind the underlying decisions.

The administrative fee also does not represent the full potential cost. Tax preparation, professional advice, and any applicable expatriation tax require separate consideration.

What changes for future travel

Renunciation affects more than the passport used at an airport. Former citizens lose the automatic right to enter and live in the United States as Americans. Future visits depend on the immigration rules applicable to their remaining nationality and individual circumstances.

The State Department also warns that someone without another nationality could become stateless, creating serious difficulties with international travel and residence. State Department guidance on loss of nationality

Americans pursuing renunciation overseas must follow a formal consular process involving required information and forms, interviews, and an in-person oath. The State Department reviews the request before approving a Certificate of Loss of Nationality.

Tax matters must be addressed separately. Certain individuals may fall under expatriation tax rules, and Form 8854 reports relevant information and certifies prior tax compliance. IRS expatriation tax guidance

For Americans considering a permanent move overseas, the decision affects family visits, employment options, financial planning,, and the possibility of returning home. A lower processing fee makes renunciation cheaper, but understanding those lasting consequences remains essential.
