Do I still have to file a U.S. tax return abroad even if the IRS has never contacted me?
Yes. U.S. citizens and green-card holders file based on worldwide income, not on whether the IRS has contacted them. If you are below the filing threshold, you may not owe a return, but having foreign accounts may still trigger FBAR or Form 8938. Streamlined Filing Compliance Procedures are designed for this exact situation.
Why silence is not safety:
- Citizen-based taxation: U.S. obligation follows passport and green card
- FATCA data exchange: Foreign banks report U.S. accounts to the IRS annually
- Treaty/CRS exchange: Broadens the reach further
- Statute of limitations: Remains open indefinitely on unfiled returns
Consequences of waiting until contacted:
- Loss of Streamlined eligibility
- Higher willful-type penalties potentially applicable
- Passport revocation for seriously delinquent debt (over $65,000 inflation-adjusted)
- Criminal exposure in severe cases
When the IRS typically learns:
| Source | Signal |
| FATCA | Foreign bank reports your TIN/SSN |
| CRS/TIEA | Treaty-based exchange |
| Form 5471/3520 IRS records | Missing filings flagged |
| U.S. broker 1099 | Cross-checked against 1040 |
| Third-party reports | Real estate, inheritance, entity structures |
Getting current:
- Streamlined Foreign Offshore: 3 years of returns, 6 FBARs
- Delinquent FBAR Submission: FBAR only, no tax owed
- Delinquent International Info Return Submission: 5471/3520 only, no tax owed
