FBAR Reporting
Foreign Bank Account Report requirements
FBAR (FinCEN Form 114, Foreign Bank Account Report) is required if you have signature authority or beneficial ownership over foreign financial accounts with aggregate balances of $10,000 or more at any time during the calendar year. File with FinCEN (not the IRS) electronically at fincen.gov by April 15 (automatic 2-month extension to June 15 for expats).
FBAR Threshold and Coverage
Any foreign account over $10k triggers FBAR requirement: aggregate threshold. Own $7k UK bank account + $5k Canadian savings = $12k (over $10k threshold, file). Include: bank accounts, savings, investment accounts, retirement accounts, insurance accounts with cash value. Exclude: foreign credit card accounts (no balance).
Report all foreign accounts on a single FBAR, even if individual accounts are under $10,000. Do not file FBAR with your tax return; file separately with FinCEN. Failure to file FBAR can result in civil penalty of 50% of the highest account balance during the year, per year of non-filing. Criminal penalties: up to 5 years imprisonment and $250,000 fine (if willful).
FBAR Filing After Deadline
Did not file FBAR? File immediately (even if late). Reasonable cause exception available if you can show foreign account did not require FBAR (below threshold) or you were unaware of requirement. FinCEN allows amended FBAR filings. Better to file late than face 50% penalty and criminal prosecution.
FBAR is separate from FATCA (see next section) and has no dollar exclusion. You must file FBAR even if using Foreign Earned Income Exclusion (FEIE) to zero out federal income tax liability. Failure to file is strictly enforced by FinCEN.
Willful FBAR Non-Filing Penalties
Willful non-filing: 50% of highest account balance per year, with no cap. Example: highest balance $5M, willful non-filing 2023-2025 (3 years) = $7.5M penalty (3 years × $5M × 50%). Criminal prosecution possible if pattern of willful evasion. FinCEN has increased enforcement; IRS criminal investigators work with FinCEN on major cases. File FBAR immediately if missed.
FATCA Compliance
Form 8938 filing requirements for expats
FATCA (Foreign Account Tax Compliance Act, Form 8938) requires U.S. citizens and residents with foreign financial assets above certain thresholds to report to the IRS. Thresholds for 2026: single filer living abroad $600,000; married filing jointly living abroad $1,200,000. U.S. residents have lower thresholds: $100k single, $200k married (higher on last day of tax year).
FATCA Threshold and Reporting
U.S. citizen in France: foreign assets $800k (over $600k threshold). Must file Form 8938. Report: bank accounts, brokerage accounts, retirement accounts, foreign real estate, stocks, bonds, insurance policies with cash value. Similar to FBAR but broader (includes real estate, investments). File with Form 1040 by April 15.
FBAR vs FATCA Overlap
FBAR: foreign bank/financial accounts $10k+ (FinCEN). FATCA: foreign financial assets $600k+ (IRS). If you have $50k foreign bank account: file FBAR (over $10k) but not FATCA (under $600k threshold). If you have $50k bank + $600k foreign stock: file both FBAR and Form 8938. Both apply if thresholds met; do not assume one exempts you from other.
FATCA also includes specific reporting for CFCs (Controlled Foreign Corporations), FPHCs (Foreign Personal Holding Companies), and foreign trusts. If you own foreign business entities or hold foreign trusts, additional filings may apply (Forms 5471, 3520, etc.).
Foreign Earned Income Exclusion
FEIE and the $126,500 limit
Foreign Earned Income Exclusion (FEIE, IRC 911) allows U.S. citizens abroad to exclude up to $126,500 (2026) of foreign earned income (wages, self-employment) from U.S. federal income tax. To qualify, you must pass the physical presence test: be outside the U.S. for at least 330 days in any 12-consecutive-month period.
FEIE Example: Significant Tax Savings
U.S. citizen in UK earning £95k (~$116k USD). No FEIE: $116k income, 37% federal tax = $42.9k. With FEIE: exclude $116k (under $126.5k limit), $0 federal income tax. Tax savings: $42.9k. Additionally: foreign housing cost exclusion (rent, utilities above base amount) can exclude additional ~$18k-$30k depending on country.
Housing Cost Exclusion (Additional Benefit)
FEIE allows additional exclusion for foreign housing costs (rent, utilities, furniture, etc.). Housing exclusion: foreign housing costs minus 16% of FEIE exclusion limit ($126.5k × 16% = $20.2k base). Example: rent €2,500/month = €30k/year (~$36k). Housing exclusion = $36k - $20.2k = $15.8k (additional exclusion). Total: $126.5k FEIE + $15.8k housing = $142.3k excluded.
Physical presence test requires 330 days outside U.S. in a 12-month rolling period. Travel days to/from U.S. do not count as U.S. presence (departure date counts as outside, arrival date counts as outside). Brief U.S. visits (vacation) count as U.S. presence. You must maintain documentation (passport stamps, airline tickets, residence proof) to prove the 330 days.
FEIE Election Revocation Rules
Once you elect FEIE, you must maintain it for 5 consecutive years (unless IRS approves early revocation). If you claim FEIE in year 1 and want to switch to Foreign Tax Credit in year 2, IRS requires written approval (difficult to obtain). Plan your FEIE election carefully; consult CPA before claiming.
Totalization Agreements
Avoiding double Social Security taxation
Totalization agreements are treaties between the U.S. and foreign countries to prevent double Social Security taxation. If you work abroad in a totalization agreement country, you contribute to the foreign country's Social Security system (not U.S.) and avoid paying both U.S. and foreign SS taxes simultaneously.
Totalization Benefit Example
U.S. citizen working in Canada (totalization agreement). Employer withholds Canadian Pension Plan (CPP) contribution (~5.95% employee + employer). Without totalization: would also owe U.S. SE tax (~15.3%) on top. Totalization: waives U.S. SE tax, saves 15.3% on income. Example: $100k income, saves $15.3k in U.S. SE tax.
Countries with Totalization Agreements
U.S. has totalization agreements with 30+ countries: Canada, Mexico, UK, Germany, France, Spain, Italy, Japan, South Korea, Australia, Chile, Denmark, Finland, Greece, Ireland, Luxembourg, Netherlands, Norway, Poland, Portugal, Sweden, Switzerland, Belgium, Brazil, Bulgaria, Czech Republic, Jamaica, Romania, and others. Check Social Security Administration website (ssa.gov/international) for complete list and country-specific rules.
To claim totalization benefits, you must be covered under the foreign country's Social Security system and have a Certificate of Coverage (issued by your country's Social Security administrator). You will submit this to your employer to stop U.S. SE tax withholding and instead contribute to the foreign system.
Foreign Tax Credit
Offsetting foreign taxes against U.S. liability
Foreign Tax Credit (FTC, Form 1118) allows a dollar-for-dollar credit for foreign income taxes paid to other countries. If you pay foreign income tax to one country and U.S. federal tax to the IRS, FTC offset prevents double taxation. Credit is limited to the lesser of foreign taxes paid or U.S. tax on that foreign income.
FTC Example: Excess Foreign Tax Credits
U.S. citizen in France earning €100k (~$110k). U.S. tax owed: $110k × 37% = $40.7k. France tax: 45% × €100k = €45k (~$49.5k). FTC: credit $49.5k foreign tax (limited to $40.7k U.S. tax). Excess credit: $49.5k - $40.7k = $8.8k. Excess FTC carries forward 1 year (or back 1 year), reducing future U.S. tax liability.
FEIE vs FTC Strategy
Cannot claim FEIE and FTC on the same income. Choose based on tax rate: FEIE better if foreign tax rate is low (15-20%) and income under $126.5k. FTC better if foreign tax rate is high (40%+) and can use credit. Example: $200k income in low-tax country (15% tax). FEIE: exclude $126.5k, pay U.S. tax on $73.5k. FTC: pay 15% foreign + 37% U.S. (gross cost higher). Use FEIE in this case.
Foreign taxes must be income taxes (not sales tax, property tax, or VAT) to qualify for FTC. You must file Form 1118 with Form 1040 to claim FTC. FTC is complex; consult CPA to determine whether FEIE or FTC is superior.
Tax Treaties
Income tax treaties and their benefits
The U.S. has income tax treaties with 60+ countries. Treaties prevent double taxation by allocating taxing rights: usually, country where income is earned has priority. U.S. allows credit for foreign taxes paid (FTC). Treaties also may provide reduced withholding rates on dividends, interest, royalties, and other investment income.
Treaty Withholding Rate Reduction
U.S. company pays U.S. citizen dividend (resident in France). Without treaty: 30% withholding. With U.S.-France treaty: 15% withholding. U.S. citizen recovers withheld 15% on French return or via U.S. Form 1118 credit. Treaty rates vary (typically 5-15% on dividends, 0-15% on interest, 0-30% on royalties). Consult treaty summary for your country.
Treaty Relief and Compliance
Claim treaty benefits by certifying residency (IRS Form W-8BEN or equivalent) with foreign financial institutions. Example: U.S. citizen owns foreign investment account. File W-8BEN to reduce withholding from 30% to treaty rate (15%). Foreign institution withholds 15% instead of 30%.
Treaty provisions vary by country. Some treaties provide FEIE alternative (use treaty provisions instead of IRC 911 FEIE). Some provide social security totalization (discussed above). Always consult the specific treaty for your country of residence.
State Residency and Taxes
State income tax obligations for expats
While abroad, you may still owe state income tax if you maintain residency in your home state (or earn income from a state). States determine residency based on: domicile (intent to make state your permanent home), active presence, maintaining a home. If you move abroad but keep a home in your home state, many states deem you a resident and impose income tax.
State Tax Residency Planning
If living abroad, consider establishing tax residency in a no-income-tax state (Florida, Texas, Nevada, Wyoming, South Dakota, Washington, Tennessee). Move your primary residence, update driver's license, voter registration, bank address. Many states defer to domicile; establishing domicile in no-tax state can avoid state tax entirely while abroad.
Maintain Residency in Tax State Carefully
If you keep a home in California while working in UK, California may claim you as resident and tax worldwide income. Some states use 'permanent place of abode' test (any residence, even part-time, creates residency). Review state tax laws before moving. Consult tax attorney on establishing no-residency (or residency in no-tax state).
States have begun claiming residents based on credit card transactions or driver's license address. If working abroad, carefully manage state residency: change address, update voter registration, establish clear intent to become non-resident. Otherwise, risk state income tax claim while living abroad.
