Many people living abroad took another citizenship years ago and assumed that was the end of their U.S. ties. For nationality purposes, it may have been. For tax purposes, the answer depends on when it happened and whether you ever told the U.S. government.
Since 2004, U.S. tax law no longer simply asks “did you lose your citizenship?”. It asks “on what date did the U.S. formally recognize it?” Until that date, you can still be treated as a U.S. taxpayer, even if you haven’t held a U.S. passport in decades.
This article explains the rule in plain English, the dates that matter, and what to do next.
The rule in plain English: IRC 7701(a)(50) and 877A(g)(4)
Two sections of the Internal Revenue Code work together:
Says you don’t stop being treated as a U.S. citizen for tax purposes until the date your citizenship is “treated as relinquished” under section 877A(g)(4).
Sets that date. It is the earliest of four events (listed below), and the first two count only if the State Department later issues you a Certificate of Loss of Nationality (CLN).
In short: losing your citizenship and stopping being a U.S. taxpayer can happen years apart. Your tax status ends on a specific, documented date, not on the day you took another nationality.
The four events that set your tax expatriation date
Your tax expatriation date is the earliest of these:
- 1RenunciationThe date you renounce U.S. citizenship in front of a U.S. consular officer. This counts only if a CLN is later issued.
- 2Signed statement of relinquishmentThe date you give the State Department a signed statement confirming that you voluntarily lost U.S. citizenship through a qualifying act, such as naturalizing elsewhere with the intention of giving up U.S. citizenship. This also counts only if a CLN is later issued.
- 3CLN issuedThe date the State Department issues your Certificate of Loss of Nationality.
- 4Naturalization cancelledThe date a U.S. court cancels a naturalized citizen’s certificate of naturalization.
For most people, event 2 is the one that applies
If you lost citizenship by taking another nationality, your tax expatriation date is the day you tell the State Department, not the day you naturalized.
Which acts can end U.S. citizenship, and how intent is judged, is covered in The Expatriating Act Explained. How relinquishing differs from renouncing is covered in Renouncing vs Relinquishing U.S. Citizenship.
Timeline: which rules apply to you
The date of your expatriating act decides which set of rules applies.
-
Before June 4, 2004
Pre-2004 rules
The good-news category
Tax status endedGenerally on the date of the act itself, if you acted with the intention of giving up U.S. citizenship, regardless of when you told anyone.
No notification was needed for tax purposes. What you still need is proof. If a bank or the IRS ever asks, a CLN showing the original date is the clearest evidence.
-
June 4, 2004 – June 16, 2008
American Jobs Creation Act of 2004
Two conditions added
Tax status endedOnly once you had both notified the State Department and filed Form 8854 with the IRS.
The 2004 law added two conditions: notify the State Department and file Form 8854 (the expatriation statement) with the IRS. Until you had done both, you stayed a U.S. taxpayer. People in this window who told the consulate but never filed Form 8854 are often still treated as U.S. taxpayers today.
-
On or after June 17, 2008
HEART Act, IRC 877A(g)(4)
Current rules
Tax status endsOn the earliest of the four events above, usually the date you give the State Department your signed statement, provided a CLN follows.
Your tax status ends on the date in section 877A(g)(4), which depends on when you notify the State Department. If you took another citizenship in, say, 2012 and never told anyone, you are still a U.S. taxpayer today.
Worked examples
Anna, naturalized in Canada in 1995
Anna became Canadian in 1995, intending to give up U.S. citizenship. She never contacted the U.S. consulate.
- Rules
- Pre-2004.
- Tax status
- Ended in 1995, so she has no U.S. tax returns to file for later years.
- What she should do
- Apply for a CLN to document the 1995 loss. Since 1990, the State Department has presumed that people who naturalize elsewhere intend to keep their U.S. citizenship. So Anna needs evidence of her intention at the time, such as a letter, a statement or an oath she took.
David, naturalized in Germany in 2010, never told the State Department
David became German in 2010. His naturalization may well have ended his U.S. citizenship for nationality purposes.
- Rules
- Current (from June 17, 2008).
- Tax status
- He has not had a tax expatriation date yet, so he is still a U.S. taxpayer.
- What happens next
-
If he submits a signed statement of relinquishment in 2026 and a CLN is issued, his tax expatriation date is the 2026 submission date, not 2010. He files a final U.S. return for 2026 with Form 8854.
To avoid being treated as a covered expatriate, he must also certify five years of U.S. tax compliance before 2026.
Maria, naturalized in France in 2006, CLN issued in 2007, no Form 8854
- Rules
- 2004–2008.
- Tax status
- She notified the State Department, but she never filed Form 8854, so under the 2004 rules she is still treated as a U.S. taxpayer.
- What she should do
- Filing Form 8854, together with the related returns, is the step that closes her case.
What to do now
-
Work out your date.
Use the timeline above. The date of your act decides which rules apply. The date you notify (or notified) the State Department decides when your tax status ends.
-
Get your Certificate of Loss of Nationality (CLN).
The CLN is the State Department’s official document confirming you are no longer a U.S. citizen. To get one after relinquishing, you contact a U.S. embassy or consulate, complete Form DS-4079 (see our guide to Form DS-4079) and submit evidence of your act and intent. The State Department fee is $450, and approval can take several months.
-
Check which U.S. tax years you still need to cover.
- Lost citizenship before June 4, 2004: usually none, once the CLN confirms the date.
- Lost it from June 4, 2004 onward: your filing obligations run up to and including the year your tax expatriation date falls in. That year you file a final return with Form 8854. Form 8854 also asks you to certify five years of prior tax compliance.
-
Look at the low-cost options before you file anything.
Many people in this position qualify for the Relief Procedures for Certain Former Citizens. They allow eligible former citizens to catch up without penalties and without being treated as covered expatriates. If you are thinking of not filing at all, read what actually happens if you renounce without filing taxes first.
