US Tax Advisors for Expats — How to Find and Vet One

US citizens and green-card holders are taxed on worldwide income regardless of where they live, with overlapping reporting requirements (Form 1040, Form 2555, Form 1116, FBAR/FinCEN 114, FATCA Form 8938, possibly Forms 5471, 8865, 3520 and PFIC reporting on 8621). The wrong preparer can cost an expat tens of thousands in unnecessary tax or penalties. This page explains how to evaluate any US tax advisor working with expats, plus a link to our vetted provider directory.

Who can legally prepare US returns

IRS Enrolled Agents (EAs) — federally licensed, full representation rights before the IRS.
Certified Public Accountants (CPAs) licensed in a US state — broader accounting credential, full representation rights.
US-licensed tax attorneys — for complex planning, controversy and litigation.
Annual Filing Season Program (AFSP) participants and unlicensed preparers — limited rights; not ideal for expat complexity.

Expat-specific experience to look for

Routine handling of Form 2555 (Foreign Earned Income Exclusion) and Form 1116 (Foreign Tax Credit).
FBAR / FinCEN 114 and Form 8938 (FATCA) reporting workflow.
Experience with PFIC reporting (Form 8621) — common trap for expats holding non-US mutual funds and ETFs.
Experience with Forms 5471 (controlled foreign corporations) and 8865 (foreign partnerships) for business owners.
Streamlined Filing Compliance Procedures and offshore voluntary disclosure for non-compliant expats.
Country-specific tax-treaty knowledge for the country you live in.

Red flags

Preparers who do not ask about foreign accounts, foreign pensions or non-US investments.
Anyone promising 'no tax owed' or 'IRS won't find out' on undeclared accounts.
Refusal to sign as paid preparer (Form 1040 has a paid preparer line — anyone preparing for a fee must sign).
Flat-fee promises with no engagement letter, no scope, and no clarity on extra forms.
PFIC, 5471 or 3520 work quoted at suspiciously low fixed prices — these forms are genuinely complex.

Questions every US expat should ask

What is your credential — EA, CPA, attorney — and your PTIN?
How many expat clients do you handle annually, and in which countries?
Do you handle FBAR, 8938, PFIC, 5471, 3520 in-house, or refer them out?
Do you offer Streamlined Filing Compliance Procedures if I am behind?
How do you handle state-tax exit / sourcing issues for expats from CA, NY, NJ?
What is your engagement-letter scope, and how are out-of-scope items billed?

How The Expats Hub directory works

Our /directory lists tax professionals that have applied and shared basic credentials. Verified members have additional checks. A directory listing is a starting point, not tax advice — always confirm credentials directly with the IRS PTIN system or relevant state board, and obtain a written engagement letter before sharing data.

Frequently asked questions

I have not filed for years — am I in serious trouble?

Often the IRS Streamlined Filing Compliance Procedures provide a path back to compliance with reduced or no penalties for non-wilful expats. A qualified expat advisor can assess eligibility. Do not ignore the issue.

Can I just use a low-cost online preparer?

For very simple expat returns, possibly. But once you have foreign accounts above FBAR thresholds, foreign pensions, non-US investments or business ownership, expat-specialist help typically pays for itself.

Do I really need to file FBAR?

If your aggregate foreign financial accounts exceed USD 10,000 at any point in the year, yes. Penalties for non-filing are significant. FATCA Form 8938 has separate, higher thresholds.

What about state taxes?

Some US states (notably California, New York, New Mexico, South Carolina, Virginia) take an aggressive view of continuing residency. A good expat advisor helps you exit cleanly and document your domicile change.

Are advisor fees deductible?

Personal tax-prep fees are not currently deductible for most individuals after the 2017 TCJA, with limited exceptions. Confirm with your advisor for your situation.
