Do U.S. citizens living abroad still have to file U.S. tax returns?

Yes. The United States taxes based on citizenship, not residency. All U.S. citizens and resident aliens must file U.S. tax returns and report worldwide income regardless of where they live. However, the Foreign Earned Income Exclusion (FEIE) allows you to exclude up to $126,500 (2024) of foreign earned income, and the Foreign Tax Credit offsets U.S. tax on foreign-sourced income by foreign taxes paid.

What happens if I didn't file while living abroad?

The IRS has programs for catching up: the Streamlined Filing Compliance Procedures are available for taxpayers whose non-compliance was non-willful. You file 3 years of delinquent returns and 6 years of FBARs, pay any tax due, and certify non-willfulness. The IRS generally waives penalties under this program. For willful non-compliance, the risks include substantial FBAR penalties and potential criminal exposure.

What is the Foreign Earned Income Exclusion (FEIE)?

The FEIE lets qualifying U.S. citizens exclude up to $126,500 (2024) of foreign earned income from U.S. taxation. To qualify, you must have a tax home in a foreign country and either: (1) be a bona fide resident of a foreign country for an uninterrupted period including a full tax year, or (2) be physically present in a foreign country for at least 330 days in any 12-month period. You claim the FEIE on Form 2555.

Key Expat Tax Provisions

Foreign Earned Income Exclusion

Exclude up to $126,500 (2024) of foreign earned income from U.S. tax. Requires bona fide residence or physical presence test. Claim on Form 2555.

Foreign Tax Credit

Dollar-for-dollar credit against U.S. tax for foreign income taxes paid. More valuable than a deduction. Excess credits can be carried back 1 year and forward 10 years. Form 1116.

In addition to the FEIE, you can exclude or deduct qualifying foreign housing expenses. Capped at 30% of FEIE limit (higher in designated high-cost cities).

FBAR (FinCEN Form 114)

Report foreign bank accounts with $10,000+ aggregate balance. File electronically with FinCEN — not the IRS. Penalties up to $100K+ for willful failures.

FATCA — Form 8938

Report specified foreign financial assets. Higher thresholds than FBAR. Penalties up to $50K/year. Filed with your tax return.

Catch-Up Programs for Unfiled Expat Returns

Streamlined Foreign Offshore

For non-willful non-compliance. File 3 years of returns + 6 years of FBARs + certify non-willfulness. IRS generally waives all penalties.

Streamlined Domestic Offshore

For U.S. residents with unreported foreign assets. Same 3+6 filing requirement but a 5% miscellaneous offshore penalty applies to foreign financial assets.

Delinquent FBAR Procedures

If your tax returns were correct but you missed FBARs, file the missing FBARs with a statement of reasonable cause. No penalty if the IRS accepts your explanation.

Delinquent International Information Return

File missing Forms 3520, 3520-A, 5471, 5472, 8865, 8938 with a reasonable cause statement. No penalty if the IRS accepts — but it's not guaranteed.
