Certificate of Loss of Nationality: What it is, Form DS-4083, and your 2026 tax obligations
A certificate of loss of nationality is the State Department record confirming an approved loss of US nationality. For tax purposes, a 2025 expatriation can also trigger Form 8854, a final dual-status return, and the rules under IRC Section 877A.
The physical certificate and the federal tax rules do not always use the same controlling date. That distinction matters when determining the 2025 covered-expatriate tests, including the $206,000 tax-liability threshold and $2 million net-worth test.
A US Certificate of Loss of Nationality also differs from a certificate of citizenship. One documents approved loss of nationality; the other documents US citizenship that was acquired or derived.
What is a Certificate of Loss of Nationality (CLN)?
A Certificate of Loss of Nationality, issued on Form DS-4083, records the State Department's approval that a person lost US nationality under 1 of the expatriating provisions in INA Section 349. It may follow formal renunciation or another qualifying voluntary act performed with the required intent.
A Certificate of Loss of Nationality (CLN), issued on Form DS-4083, is the official US government document confirming that the State Department has approved your voluntary relinquishment or renunciation of US nationality.
The certificate of loss of nationality of the United States is created through a State Department process. A diplomatic or consular officer develops the case, but the officer's finding does not itself approve the loss.
Form DS-4083 is then used by the Department to record and certify the approved loss. The State Department's Foreign Affairs Manual expressly identifies DS-4083 as the CLN used for that purpose.
The DS-4083 is the State Department document used to certify an approved loss of US nationality, and the determination is generally final once issued.
The State Department states that an approved loss is final and irrevocable, subject to INA Section 351 and successful administrative or judicial review.
If you are considering expatriation, see our guide to renouncing US citizenship before separating the citizenship process from the tax filing that follows.
The State Department rules for relinquishing US nationality abroad explain the INA Section 349 routes and the required consular process.
Who needs a Certificate of Loss of Nationality?
A CLN may be needed after 1 approved loss-of-nationality case to document that the person is no longer a US national. It can matter to former citizens, foreign authorities, financial institutions, and taxpayers completing post-expatriation records such as Form 8854.
The following 5 situations are common reasons a former citizen may need the document:
- Formal renunciation abroad. A person who completes the INA Section 349(a)(5) process receives a CLN if the State Department approves the loss.
- Prior relinquishing act. A person may request recognition of a qualifying act under INA Section 349(a)(1)–(4) if the act was voluntary and performed with intent to relinquish US nationality.
- Foreign government records. A dual national may need loss of nationality documentation when another government asks for evidence of current nationality status.
- Financial institution records. A bank may request a CLN when resolving US indicia or updating FATCA-related customer records after citizenship loss.
- US tax records. A former citizen may need the CLN when documenting expatriation facts connected with Form 8854 or another IRS request.
Banks, foreign governments, and the IRS may each have a reason to request a CLN, but the document does not by itself erase prior US tax obligations.
Citizenship status can differ from the concepts used in US tax law. Our guide to US nationals versus US citizens at birth explains that distinction.
Form DS-4083: The official Certificate of Loss of Nationality explained
Form DS-4083 is the State Department's official certificate recording an approved loss of US nationality. At least 1 consular officer develops the case, while actual approval rests with the Department rather than the applicant or the individual consular post.
A DS-4083 certificate of loss of nationality is therefore not an application that you download, complete, and mail to Washington, DC.
- Personal data: The certificate identifies the person whose loss of nationality has been approved.
- Expatriating act: It records the legal basis and relevant facts supporting the Department's determination.
- Consular certification: A diplomatic or consular officer certifies the facts developed in the loss-of-nationality case.
- Department approval: State Department approval makes the finding operative for nationality purposes.
The Form DS-4083 Certificate of Loss of Nationality belongs to a broader case file that can also include DS-4079, DS-4080, DS-4081, and, where applicable, DS-4082.
Put another way, the DS-4083 form from the US State Department is prepared through the government process, not self-filed by the former citizen.
You cannot submit Form DS-4083 yourself – a consular officer develops the case, and the State Department makes the final approval decision.
See our explanation of how the US citizenship renunciation process works for the steps surrounding the certificate.
Voluntary relinquishment vs. formal renunciation: Which produces a CLN?
Both routes can result in Form DS-4083, but they arise under different parts of INA Section 349. Formal renunciation uses Section 349(a)(5), while voluntary relinquishment may rely on a prior qualifying act under Sections 349(a)(1)–(4) performed with intent to give up nationality.
Formal renunciation requires an oath of renunciation before a US diplomatic or consular officer abroad. The State Department currently requires 2 interviews, with at least 1 conducted in person.
Voluntary relinquishment instead asks the Department to determine whether a prior expatriating act caused loss of nationality. Naturalization in another country can be such an act, but intent remains central.
For federal tax purposes, a prior relinquishing act does not automatically move the IRC Section 877A expatriation date back to the historical act date.
For a former citizen, the tax date is determined under the specific IRC Section 877A(g)(4) rules in the Form 8854 instructions. One possible date is when a signed relinquishment statement is furnished to the State, provided the Department later issues a CLN.
A past relinquishing act and the federal tax expatriation date can differ, so the Form 8854 date must be determined under IRC Section 877A rather than assumed from the historical act.
See our Form 8854 guide for expatriates before using a nationality date in an exit-tax calculation.
How to obtain Form DS-4083: Step-by-step process
Obtaining Form DS-4083 requires a State Department loss-of-nationality case rather than a self-filed form. In 2026, formal renunciation abroad requires 2 consular interviews, at least 1 in person, completion of the required documents, and an in-person oath under INA Section 349(a)(5).
The following 7 steps describe the current process:
- Confirm the legal route and intent. Decide whether the request is formal renunciation or recognition of a prior relinquishing act.
- Contact a US embassy or consulate. Request a renunciation appointment or instructions for a relinquishment case at the post serving your location.
- Prepare for the $450 CLN fee. The State Department reduced the administrative-processing fee from $2,350 to $450 effective April 13, 2026.
- Complete 2 interviews. Current State Department rules require 2 interviews, with at least 1 held in person.
- Execute the required documents. Formal renunciation includes taking the oath of renunciation in person.
- Wait for Department review. The consular officer develops the file, and the State Department makes the final determination.
- Keep the approved CLN. Once issued, retain the DS-4083 form with your permanent nationality and tax records.
The Form DS-4083 US State Department process therefore begins with the appropriate consular post, not with an IRS filing.
A citizenship renunciation fee is separate from any US tax preparation cost or expatriation tax that may arise.
See TFX's discussion of Americans choosing to expatriate for related context.
Certificate of Loss of Nationality processing time
The State Department does not publish a universal 3–6 month CLN processing guarantee in its current loss-of-nationality instructions. Timing includes local appointment availability, 2 required interviews, document completion, and Department review, so the total period can differ materially by consular post and individual case.
That makes expatriation certificate processing time different from a fixed government service standard.
The tax filing date should be tracked separately. For a 2025 expatriation, attach the initial Form 8854 to your Form 1040, 1040-SR, or 1040-NR for the year containing your expatriation date if you are required to file an income tax return. If you are not required to file an income tax return, file Form 8854 separately by the date the applicable return would have been due, including extensions.
A person using voluntary relinquishment should not assume that the historical expatriating act alone controls that date. The Form 8854 instructions contain 4 possible tax dates for former citizens.
Tax implications of receiving a Certificate of Loss of Nationality
A CLN does not end every US tax obligation on the date the paper arrives. For a person who expatriated in 2025, Form 8854 applies to the year containing the federal tax expatriation date, and a former citizen may also have a dual-status income tax return for that year.
The following 5 tax issues should be reviewed for a 2025 expatriation filed in 2026:
- Final dual-status return. A former citizen who is a nonresident at year-end generally files Form 1040-NR as the return and attaches the required Form 1040 statement for the resident portion.
- Form 8854. The initial expatriation statement is attached to the income tax return for the year containing the expatriation date.
- Five-year certification. Form 8854 asks whether the taxpayer complied with federal tax obligations for the 5 tax years preceding expatriation.
- Covered-expatriate determination. The 2025 income-tax, net-worth, and compliance tests must be checked separately.
- Exit tax. A covered expatriate may be subject to the IRC Section 877A mark-to-market regime and special rules for deferred compensation, tax-deferred accounts, and nongrantor trusts.
A tax compliance certification is not a statement that the taxpayer merely filed Form 8854. The 2025 instructions require certification of applicable federal tax obligations for the preceding 5 years.
Failure to file a required Form 8854, or filing it with missing or incorrect information, carries a $10,000 penalty for that year unless the reasonable-cause exception applies.
For more on special post-expatriation income rules, see our guide to covered expatriates and deferred compensation.
Covered expatriate status and the exit tax
For a 2025 expatriation, covered-expatriate status is triggered by any 1 of 3 tests: average annual net income tax above $206,000, net worth of at least $2 million, or failure to certify 5 preceding years of federal tax compliance on Form 8854.
For 2025, meeting any 1 of the following 3 tests can make an expatriate a covered expatriate, subject to statutory exceptions for qualifying dual citizens and certain minors.
| 2025 test | Threshold | Result |
|---|---|---|
| Average annual net income tax liability | More than $206,000 for the 5 preceding tax years | Covered-expatriate test met |
| Net worth | $2 million or more on expatriation date | Covered-expatriate test met |
| Five-year compliance certification | Failure to certify compliance on Form 8854 | Covered-expatriate test met |
A covered expatriate is generally treated as selling most worldwide property at fair market value on the day before expatriation.
For 2025, the resulting net deemed gain is reduced, but not below zero, by $890,000. Specific deferred compensation, tax-deferred accounts, and nongrantor trusts follow separate rules.
A taxpayer below both financial thresholds can still become a covered expatriate by failing the 5-year federal tax compliance certification.
Certain dual citizens at birth and certain minors can qualify for exceptions to the first 2 tests. They still must file Form 8854 and make the 5-year compliance certification.
See our guide to US tax rules for dual citizens when checking that statutory exception.
Form 8854: Filing requirements after your CLN is issued
For a 2025 expatriation, the initial Form 8854 is generally due with the income tax return for the year containing the federal expatriation date. The form also tests 5-year federal tax compliance, records assets and liabilities, and identifies whether IRC Section 877A treatment applies.
The following 5 filing steps cover the main Form 8854 requirements:
- Attach the initial Form 8854 to the expatriation-year return. For a former citizen who is nonresident at year-end, that is generally a Form 1040-NR dual-status return with the required statement.
- Certify the preceding 5 years. Review all applicable income tax, employment tax, gift tax, information-return, interest, and penalty obligations covered by the IRS certification.
- Report assets and liabilities. Form 8854 requires balance-sheet information and values used for the covered-expatriate analysis.
- Calculate Section 877A amounts when applicable. A covered expatriate applies the mark-to-market or special-category rules to the relevant property and rights.
- Check future annual filing duties. Annual Form 8854 filing can continue for deferred tax, eligible deferred compensation, or interests in nongrantor trusts.
A person looking for a final tax return expat filing should not assume that “final return” means Form 1040 alone. Dual-status mechanics depend on residency status at the end of the year.
If earlier returns or international information forms are missing, do not certify compliance until the facts have been reviewed.
Eligible taxpayers with non-willful prior failures may consider the IRS Streamlined Filing Compliance Procedures.
Our guide to Relief Procedures for Certain Former Citizens explains a separate IRS route for eligible former citizens.
CLN vs. Certificate of Citizenship vs. Naturalization Certificate: Key differences
These 3 documents prove opposite or different citizenship events. Form DS-4083 records approved loss of US nationality; Form N-560 documents acquired or derived citizenship; and Form N-550 is the certificate issued after a person completes the US naturalization process.
A CLN documents loss of nationality, while Form N-560 and Form N-550 document forms of US citizenship rather than its loss.
| Document | Issuing agency | Purpose | Who receives it |
|---|---|---|---|
| CLN, Form DS-4083 | US Department of State | Records approved loss of US nationality | Former US citizen or national after an approved case |
| Certificate of Citizenship, Form N-560 | USCIS | Documents acquired or derived US citizenship | Eligible US citizen |
| Certificate of Naturalization, Form N-550 | USCIS | Documents citizenship obtained by naturalization | Naturalized US citizen |
A US citizenship certificate such as Form N-560 is therefore not a substitute for a CLN.
The Form N-560 is a citizenship document. The N-560 form refers to the same USCIS Certificate of Citizenship.
A naturalization document serves a different purpose. Form N-550 confirms naturalization, while a consular report of birth abroad can document citizenship acquired at birth abroad in qualifying cases.
A document for citizenship proves citizenship status. A CLN proves an approved loss of that status.
So, how to obtain a certificate of citizenship? An eligible person generally uses the applicable USCIS process, commonly Form N-600, rather than the State Department CLN process. First identify whether the needed record is Form N-560, N-550, or another citizenship record because the filing agency and eligibility rules differ.
A person with a split-year US status may also need our guide to filing a US dual-status tax return.
Cost and fees: How much does it cost to get a Certificate of Loss of Nationality?
As of August 24, 2026, the State Department fee for administrative processing of a CLN request is $450. The final rule took effect April 13, 2026, reducing the former $2,350 fee by $1,900, or about 80%.
The following 4 cost categories can arise:
- State Department fee – $450. This is the current government fee for administrative processing of the CLN request.
- Separate CLN document fee – $0. The $450 charge is the administrative-processing fee for the request; there is no other listed State Department fee for issuing DS-4083.
- US tax preparation costs – case-specific. The amount depends on forms, prior-year compliance, investments, entities, and whether an exit-tax calculation is required.
- Potential expatriation tax – case-specific. A covered expatriate can face IRC Section 877A tax consequences beyond the consular fee.
The 2026 State Department CLN fee is $450, but that government charge does not cover Form 8854 preparation or any federal tax due under IRC Section 877A.
This is one of the clearest 2026 changes to older expatriation guidance. Any source still stating a current $2,350 fee is using the pre-April 13, 2026 amount.
Dual citizenship considerations before renouncing
US law does not require a person to hold a second nationality before requesting renunciation, but the State Department warns that a person without another nationality can become stateless. That can mean losing the protection of any national government and lacking a passport after the CLN is approved.
Confirm the legal security of your dual citizenship before the renunciation appointment if your goal is to retain another nationality.
The Exclusive Citizenship Act of 2025, S. 3283, was introduced on December 1, 2025, and referred to the Senate Judiciary Committee. It is a proposed bill, not a rule that automatically ended dual citizenship.
The proposal is broader than a restriction limited to federal employees. Its introduced text concerns exclusive allegiance and dual citizenship generally.
See our discussion of the Exclusive Citizenship Act of 2025 for the proposal's potential implications.
Renouncing US citizenship without another secure nationality can leave a person stateless, which can affect passports, travel, residence rights, and consular protection.
What happens after you receive your CLN: Post-renunciation obligations
Receiving a CLN ends US nationality under the approved State Department determination, but at least 5 separate tax and financial tasks may remain. For a 2025 expatriation, those can include the dual-status return, Form 8854, FBAR, financial-institution updates, and future US-source income reporting.
The following 5 post-CLN obligations deserve review:
- File the expatriation-year return. A former citizen who is nonresident at year-end generally uses the applicable dual-status Form 1040-NR filing method.
- File Form 8854. The initial statement certifies 5-year federal tax compliance and reports information required under Sections 877A and 6039G.
- Update financial institutions. A bank or broker may request the CLN when updating citizenship, FATCA, or withholding records.
- Check the final FBAR obligation. A person who was a US person during part of 2025 may still have a 2025 FBAR if aggregate reportable foreign accounts exceeded $10,000.
- Review later US-source income. As a nonresident alien, some US-source FDAP income can be subject to 30% gross withholding, unless a treaty or another rule changes the rate.
A former citizen keeping US rental property needs separate review. Gross US real-property rent can fall under the 30% regime unless a valid election treats the income as effectively connected and allows net-basis taxation.
See our guide to US tax obligations while living abroad for the rules that apply before nationality ends.
What to do if you lose your Certificate of Loss of Nationality
A lost DS-4083 should be handled through the State Department's passport and citizenship records system, not through USCIS Form N-565. State Department records specifically include Form DS-4083, and requests involving CLN records are routed through the Bureau of Consular Affairs records function.
Form N-565 is for replacement naturalization and citizenship documents issued through USCIS. Its 2025 instructions cover Certificates of Naturalization, Certificates of Citizenship, Declarations of Intention, and Repatriation Certificates.
It does not list Form DS-4083 as a document that USCIS replaces.
Do not confuse CLN record replacement with Form N-565 – N-565 replaces specified USCIS naturalization or citizenship documents, not the State Department's DS-4083.
Keep both physical and secure digital copies of your loss of nationality documentation once received.
Common mistakes to avoid during the renunciation and CLN process
Six recurring errors can create tax or documentation problems after expatriation. For a 2025 expatriation, the highest-risk mistake is failing to verify the 5 preceding years before making the Form 8854 compliance certification, because that failure alone can trigger covered-expatriate status.
The following 6 mistakes should be checked before closing the file:
- Waiting for the paper CLN without tracking Form 8854. Determine the IRC Section 877A expatriation date and the return deadline under the tax rules.
- Assuming renunciation cancels old taxes. The State Department expressly warns that prior US tax obligations can remain after nationality loss.
- Skipping the 5-year certification review. Failure to certify the preceding 5 years can produce covered-expatriate status regardless of the $206,000 or $2 million tests.
- Renouncing without another nationality secured. The State Department warns that the person may become stateless.
- Ignoring prior information reporting. Review applicable Form 8938 and other federal information returns, plus any separate FBAR duties, before making compliance statements.
- Using a CLN as proof of current citizenship. The certificate proves an approved loss of US nationality, not current US citizenship.
Renouncing US citizenship does not erase tax liabilities or filing duties that arose before the federal tax expatriation date.
If prior conduct was willful or may involve fraud, streamlined filing may not be the correct route. See our guide to IRS Criminal Investigation voluntary disclosure and Form 14457.
Countries where US expats most commonly obtain a CLN
No current State Department dataset establishes an official top 6 country ranking for CLN requests or proves that one embassy has the longest queue in 2026. Appointment availability is post-specific, so country-by-country wait claims should not be presented as official facts without current local evidence.
The 6 locations named in the brief are still useful places to check individually because they have established US consular services and sizable US-connected populations:
- Canada – check the US post serving your province for current loss-of-nationality appointment instructions.
- United Kingdom – confirm the current process directly with the US Embassy in London.
- Germany – use the embassy or consulate instructions applicable to your residence.
- Australia – confirm which US consular post handles your request and its current appointment process.
- Israel – check the applicable US mission's current instructions before arranging the 2 required interviews.
- Switzerland – verify the current post-specific process rather than relying on a historical wait-time estimate.
The State Department's national guidance says applicants abroad should contact the nearest US embassy or consulate for further information.
Our guide to countries that permit dual citizenship can help with the nationality question before relinquishing citizenship.
Frequently asked questions
There is no current State Department rule promising a universal 3–6 month processing period. The total time depends on the 2 required interviews, appointment availability, case completeness, and Department review. Contact the embassy or consulate handling your case for its current timetable.
Yes. INA Section 349(a)(1)–(4) can support a Certificate of Loss of US Nationality when a qualifying expatriating act was voluntary and performed with the required intent. The State Department still reviews the case and requires 2 interviews, with at least 1 in person.
No. The State Department warns that US tax obligations can remain after nationality loss. For a 2025 tax expatriation, you may need a dual-status return and Form 8854, while liabilities and reporting duties from earlier years remain governed by the applicable tax rules.
DS-4083 records an approved loss of US nationality. Form N-560 is a Certificate of Citizenship documenting acquired or derived citizenship. The 2 records serve opposite functions, so a person seeking proof of nationality loss should not use an N-560 citizenship certificate instead.
The State Department's administrative processing fee is $450 for the current process. That amount became effective April 13, 2026, replacing the former $2,350 fee. It does not include private tax-preparation costs or any tax that could arise under IRC Section 877A.
Request the relevant CLN record through the State Department's passport and citizenship records process. Do not file USCIS Form N-565 for DS-4083. N-565 covers specified naturalization and citizenship documents, while State Department records expressly include CLNs.
Do not use physical delivery as the sole tax deadline. Form 8854 is tied to the federal expatriation date under IRC Section 877A(g)(4), and the initial form is due with the return for that year. Some tax dates depend on a CLN later being issued, so confirm the facts before filing.
An approved CLN is generally final and irrevocable. The State Department identifies limited exceptions, including INA Section 351 and successful administrative review or judicial appeal. Its rules also reference 22 CFR 50.51 for administrative review of prior loss-of-citizenship determinations.
A certificate of loss of nationality US filing and a tax expatriation filing are related, but they are not interchangeable processes.
