If you're a U.S. citizen or green card holder living abroad, FATCA and FBAR compliance isn't optional—it's a legal requirement with penalties that can reach 50% of unreported account balances. Choosing the right advisor means knowing exactly what questions to ask and which red flags to avoid. This guide walks you through the expertise markers that separate competent international tax professionals from those who'll leave your accounts exposed.
Why FATCA and FBAR Matter More Than You Think
FATCA (Foreign Account Tax Compliance Act) and FBAR (Foreign Bank Account Report) serve different purposes but both demand strict adherence. FBAR requires disclosure of foreign financial accounts exceeding $10,000 in aggregate; FATCA applies to "specified foreign financial assets" valued over $200,000 to $600,000 depending on your filing status and residency. The IRS matches data from foreign banks directly to your tax returns. Missing either filing can trigger civil penalties of $10,000+ per year per account, or criminal prosecution in egregious cases.
Ask Your Advisor About Specific FBAR Thresholds
Before hiring anyone, confirm they understand the nuances. Request clarification on:
- Whether they know the $10,000 aggregate threshold applies across all your accounts (bank accounts, investment accounts, cryptocurrency exchanges)
- How they handle "signature authority" accounts (accounts you can control but don't own, which still trigger FBAR filing)
- Their process for identifying accounts that fall below FBAR but still require FATCA Form 8938 disclosure
A qualified advisor should answer without hesitation. If they seem uncertain or offer vague responses, move on. This is foundational material for anyone claiming international tax expertise.
Evaluate Their FATCA Form 8938 Experience
FATCA filings are more complex than FBAR. The Form 8938 has different thresholds, filing deadlines, and penalties than FBAR, and many expats need both forms simultaneously. Ask your advisor:
- "How many clients have you filed Form 8938 for in the past two years?"
- "What's your process for calculating fair market value for cryptocurrency, international brokerage accounts, and foreign pensions?"
- "Do you track changes to FATCA thresholds, and how do you notify clients when they're triggered?"
Advisors with 10+ clients annually on Form 8938 have seen enough edge cases to anticipate problems. Those handling fewer than 5 annually may lack the depth you need.
Verify Their Currency Conversion and Reporting Protocol
Foreign accounts held in euros, pounds, pesos, or other currencies create reporting headaches. Ask specifically:
- Which exchange rate they use (IRS requires year-end rates for most FBAR reporting)
- How they handle multi-currency accounts and historical conversions for amended returns
- Whether they use specialized software or manual tracking for currency fluctuations
Advisors who mention using dedicated software like MoneyLion, OFX aggregators, or tax platforms with built-in currency tools are typically more efficient. Manual tracking suggests slower turnaround and higher error risk.
Understand Their Penalties and Streamlined Filing Approach
If you've missed prior years of FBAR or FATCA filings, your advisor's strategy matters enormously. Ask whether they're familiar with:
- The IRS Streamlined Filing Compliance Procedures (SFCP) for non-willful errors
- The Reasonable Cause standard under IRC §6664
- Timeline differences: Streamlined filings go back 3 years for returns and 6 years for FBARs
Advisors recommending Streamlined Procedures upfront typically cost $2,500–$5,000 for a multi-year catch-up. Those pushing full amended returns without exploring Streamlined options may inflate your tax bill by 30–50%.
Check Credentials and Specialization
Look for advisors holding these credentials:
- Enrolled Agent (EA) – Direct IRS representation authority
- CPA with international tax specialization – Can represent you and likely has deeper technical knowledge
- Tax attorney (if you face potential penalties) – Privileged communication protection during investigations
A CPA or EA with 5+ years specifically in expat taxation will charge $250–$400/hour; generalists or recently credentialed professionals often charge $150–$250/hour but may require more billable hours due to learning curves.
Red Flags to Avoid
Don't hire advisors who:
- Claim FBAR is "optional" or "rarely audited"
- Can't explain the difference between FBAR and FATCA filing requirements
- Offer flat-fee services without asking detailed questions about your account structure
- Don't mention compliance tracking going forward (one-time filing without systems to catch future accounts)

Frequently Asked Questions
Q: Do I need both FBAR and FATCA filings, or just one? Most expats with foreign accounts need both, since they have overlapping but distinct requirements; your advisor should automatically assess both during intake.
Q: Can I file FBAR and my tax return on different dates? FBAR (FinCEN Form 114) is due April 15 with an automatic extension to October 15, while Form 8938 is part of your 1040 and follows the same deadline, so coordinating both is essential.
Q: What happens if I discover I missed FBAR filings from three years ago? Consult an international tax professional immediately about Streamlined Procedures, which may allow you to file back years without criminal exposure, but you'll need professional guidance on your specific situation.
