What happens if I just found out I’m a U.S. citizen and have never filed a tax return?
You should come into compliance as soon as possible, and the Streamlined Foreign Offshore Procedures (SFOP) lets you do it without penalties when your failure to file was non-willful. Many people born abroad to a U.S. citizen parent, or born on U.S. soil and raised elsewhere, discover the filing obligation years or decades late. The IRS has a clear path forward.
SFOP catch-up requirements:
- File the last 3 years of delinquent Form 1040s
- File the last 6 years of FBARs (FinCEN 114)
- Submit Form 14653 certifying that your non-filing was non-willful
- Pay any tax and interest due (often zero after FEIE/FTC relief)
What “non-willful” means in practice:
| Scenario | Likely non-willful? |
| Didn’t know you were a U.S. citizen | Yes |
| Knew you were a citizen but not about filing | Yes |
| Filed some years, skipped others intentionally | Risky; consult a tax professional |
| Received IRS notices and ignored them | No |
Most first-time filers who have lived outside the U.S. their entire lives owe little or no U.S. tax after applying the Foreign Earned Income Exclusion (up to $130,000 for 2025) or the Foreign Tax Credit.
If you’re considering renunciation after becoming compliant, that involves a separate process with Form 8854 and a potential exit tax.
