For an American who wants to renounce his or her citizenship, doing so is a very big step indeed, going way beyond merely giving up one’s passport. It might be seen by those who have spent their whole lives abroad as a means of simplifying their financial affairs.
There are legal processes involved, tax obligations and other financial implications in relinquishing one’s US citizenship. These all need serious contemplation, since each move made may have significant implications for the future.
By 2026, people making such a choice will have to be aware of how US tax laws will affect their income, investments, retirement funds, and any foreign property holdings. For Americans who are residing in Switzerland, harmonizing one’s last tax filing in the US with one’s declaration duties in Zurich might also become crucial.
This guide explores the essential steps, tax implications, and planning strategies to consider before renouncing US citizenship.
Understanding US Citizenship Renunciation
Renouncing US citizenship is the formal legal process through which an American voluntarily gives up their US nationality.
Unlike changing tax residency or obtaining another passport, renunciation requires an official procedure administered by the US Department of State.
Generally, individuals must appear before a US diplomatic or consular officer abroad, complete the necessary documentation, and take an oath of renunciation.
Once the Department of State approves the renunciation and issues a Certificate of Loss of Nationality (CLN), the loss of citizenship is generally permanent.
Renunciation also means losing rights associated with US citizenship, including unrestricted access to live and work in the United States and eligibility for a US passport. Future travel and residence depend on applicable immigration laws.
Importantly, renouncing citizenship and completing US tax obligations are two separate processes. Receiving a CLN does not automatically resolve outstanding IRS filing responsibilities.
Essential Steps Before Renouncing Citizenship
Before starting the renunciation process, individuals should evaluate their legal status, financial position, and plans.
1. Confirm your alternative citizenship
Having another nationality is strongly recommended before renouncing US citizenship.
Without another citizenship, an individual could become stateless, creating serious challenges involving travel, employment, residence, and access to government services.
2. Review your financial position
Prepare a detailed overview of your worldwide assets, including property, investments, pensions, savings, and business interests.
Understanding their value can help determine whether expatriation tax rules may apply.
3. Review previous US tax filings
Check whether the previous five years of federal tax returns and required information filings are accurate and complete.
4. Arrange the consular process
Please contact the appropriate US embassy or consulate for information regarding appointments, documentation, and costs.
The Department of State’s process includes interviews, required forms, and an in-person oath.
5. Prepare for post-renunciation responsibilities
Review your banking, investments, retirement, insurance coverage, and immigration situations.
This can be useful to do beforehand to prevent any issues.
US Tax Obligations Before Renunciation
One of the biggest misconceptions about citizenship renunciation is that tax responsibilities disappear immediately after the legal process is completed.
In reality, US citizens are generally required to report worldwide income until their citizenship ends for federal tax purposes.
Depending on their circumstances, this can include:
- Employment income earned abroad
- Foreign business or freelance earnings
- Rental income from overseas properties
- Interest, dividends, and capital gains
- Certain foreign pension and retirement income
- Income from trusts and other investments
Additional reporting obligations may arise under the Foreign Bank Account Report (FBAR) and the Foreign Account Tax Compliance Act (FATCA).
Someone living in Switzerland, for example, may need to coordinate US worldwide income reporting with Swiss federal, cantonal, and municipal taxation.
Completing previous US tax returns is especially critical in that the IRS demands a certificate of good tax standing for five years from the expatriating individual so as not to become a covered expatriate according to the certification test.
Understanding the Expatriation Tax and Exit Tax
The US exit tax, otherwise known as the expatriation tax, is a tax that is levied on certain individuals who give up their US citizenship or US residency.
Under Internal Revenue Code Section 877A, covered expatriates may be treated as though they sold most of their worldwide property at fair market value immediately before expatriation.
This is known as the mark-to-market tax regime.
For example, someone who purchased investments several years ago may have substantial unrealized gains, even though they haven’t sold those investments.
If they qualify as a covered expatriate, some of those gains may become taxable under the deemed-sale rules.
The law provides an inflation-adjusted exclusion for certain net unrealized gains. For 2025, that amount was $890,000; the applicable 2026 exclusion must be used for a 2026 expatriation.
Special rules apply to deferred compensation, specified tax-deferred accounts, and interests in nongrantor trusts. These items are not necessarily subject to the ordinary deemed-sale calculation.
Not all those who give up their citizenship will be liable for exit taxes. The result will depend on whether one is considered to be a covered expatriate and other factors.
Who May Be Classified as a Covered Expatriate?
Understanding covered-expatriate status is essential because it determines whether the special exit tax rules may apply.
For individuals expatriating in 2026, the IRS generally applies three tests.
Test
2026 requirement
Net worth test Worldwide net worth of $2 million or more
Average income tax liability test Average annual net income tax liability above $211,000 over the previous five tax years
Tax compliance certification test Failure to certify five years of federal tax compliance on Form 8854
Meeting any one of these conditions generally results in covered-expatriate status.

Certain dual citizens from birth and qualifying individuals who expatriate before reaching age 18½ may qualify for limited exceptions to the income tax liability and net worth tests.
However, these exceptions have specific eligibility requirements, and the five-year tax compliance certification remains important.
A professional assessment before renunciation can help individuals understand whether they qualify as covered expatriates and what that means for their financial situation.
Form 8854 and Final Tax Reporting Requirements
IRS Form 8854, officially known as the Initial and Annual Expatriation Statement, is a central part of the US expatriation tax reporting process.
The form allows qualifying individuals to certify compliance with their previous five years of federal tax obligations and disclose information relevant to their expatriation status.
Citizens who surrender their citizenship during any one year may be required to file a dual-status income tax return, which could involve Forms 1040 and 1040-NR.
Significant considerations for reporting purposes are:
- Filing the appropriate final US federal income tax return
- Completing Form 8854 accurately
- Reporting income earned before and, where applicable, after expatriation under the relevant tax rules
- Meeting applicable FBAR and foreign asset reporting obligations
- Reporting any expatriation tax liability
Form 8854 is normally submitted along with the expatriate’s income tax return for the expatriation year. Failing to provide all necessary information will give rise to compliance problems.
Keeping a complete record of submitted forms and supporting financial documents is advisable.
Foreign Assets, Investments and Income Considerations
Renouncing citizenship can affect how international financial assets are treated for US tax purposes.
Foreign investments, retirement plans, real estate, and business interests may have varying repercussions based on ownership, tax considerations, and covered expatriate considerations.
For Americans living in Switzerland, all of these become very complicated.
For instance, a person may hold Swiss bank accounts, investment portfolios, retirement savings, and property while remaining subject to US reporting rules.
The same assets may also be relevant to their annual tax declaration in Zurich, although Swiss reporting and valuation rules differ from those used in the United States.
Swiss pension arrangements deserve particular attention because their US tax classification may differ from their treatment under Swiss law.
Business ownership and foreign investment funds can introduce additional reporting challenges.
In addition, covered expatriates can cause future tax liabilities for some gifts and inheritances received by citizens or resident aliens of the US.
Examining such property before renunciation can help in recognizing any tax liability issues.
Tax Planning Before and After Renunciation
Effective expatriation planning should begin well before a consular appointment.
The goal is to understand the consequences of renunciation and manage applicable obligations legally and efficiently.
Before renunciation
Begin with the review of past US tax returns to determine any compliance issues.
Then comes the valuation of all global assets and consideration for covered expatriate classification.
Review retirement accounts, investments, unrealized capital gains, business interests, and anticipated income.
For individuals living in Switzerland, coordinating US expatriation planning with Swiss tax obligations can also help identify differences in the timing and treatment of income or gains.
Any proposed restructuring or asset disposal should be assessed for genuine commercial purpose and potential tax consequences in both jurisdictions.
After renunciation
Once renunciation becomes effective, individuals should complete any remaining US tax filings and retain their Certificate of Loss of Nationality.
Former citizens may continue to have US tax responsibilities if they receive US-source income, own US property, or have other taxable connections to the country.
They should also review their updated status with banks, investment providers, and other relevant financial institutions.
Renunciation does not necessarily eliminate every future US tax obligation.
Common Renunciation and Tax Compliance Mistakes
Several mistakes can make the expatriation process more complicated than necessary.
Considering that the loss of nationality terminates tax obligations: The fact that you are not a citizen of the country anymore does not terminate your tax obligations.
Not considering Form 8854: Not completing the form leads to becoming a covered expatriate.
Underestimating worldwide net worth: Assets held outside the United States may still count toward the relevant net worth threshold.
Overlooking retirement and investment accounts: Different asset categories may receive different tax treatment.
Failure to review past tax returns: Inaccuracies and missed disclosure could become a problem during the expatriation process.
Failure to think about future travel and residence: Expatriates will usually have to meet US immigration requirements to enter and reside in the country.
Avoiding these mistakes requires preparation, accurate documentation, and an understanding of both legal and financial responsibilities.
Professional Guidance for Complex Expatriation Cases
Renunciation combines US nationality law, international tax regulations, estate planning, and local-country taxation.
With regard to people who have foreign investments, pension plans, property, and business interests, such topics can become very complicated.
A good cross-border tax professional will be able to examine exit taxes, analyze past tax filings, prepare documents related to expatriate taxes, and facilitate international tax filings.
For Americans living in Zurich, advice from professionals familiar with both US tax regulations and Swiss taxation may be particularly valuable.
Legal advice from a qualified nationality or immigration lawyer may also be necessary when evaluating the consequences of giving up citizenship.
The objective is not simply to complete the renunciation process, but to ensure the tax declaration zurich decision is informed, properly documented, and consistent with long-term financial goals.
Conclusion
Giving up US citizenship in 2026 is an important choice from a legal and financial perspective and involves more than filling out paperwork at a US embassy or consulate.
Understanding the process of renunciation, analyzing the past five years’ tax compliance history with respect to federal taxes, identifying potential exit taxes, and completing form 8854 is an integral part of the process.
Americans residing in Switzerland may coordinate their expatriation filing responsibilities with the required tax filing in Zurich in order to lessen tax reporting discrepancies.
Financial accuracy, realistic values for assets, and an awareness of future tax liability in the US are equally significant.
With proper planning and professional advice, if needed, people can take up citizenship renunciation with more knowledge and certainty.
The right planning will enable people to make sure that the decision they make in life will contribute to their goals in life.
