With more than three decades of experience serving Americans abroad, Barron's International Tax Service provides specialized knowledge of U.S. international tax compliance. From individual income tax returns and foreign financial asset reporting to complex foreign corporation filings and expatriation matters, we offer personalized attention and practical guidance tailored to each client's circumstances.
Many Americans living abroad are unaware that they must continue filing U.S. tax returns and reporting foreign financial accounts, even when they owe little or no U.S. income tax.
The IRS Streamlined Foreign Offshore Procedures allow eligible taxpayers whose failure to comply was non-willful to bring their U.S. tax filings up to date, generally without the penalties associated with delinquent returns and foreign account reporting.
Our services include:
We provide experienced, confidential, and personalized assistance to help you resolve outstanding filing obligations and move forward with confidence.

For Americans who have made their lives abroad, continuing U.S. tax obligations can become burdensome.

At Barron's International Tax Service, we help Americans navigate the complex U.S. tax requirements associated with renouncing citizenship.

Hello, I'm Barron Harper. For more than 30 years, I've helped Americans abroad navigate the complexities of U.S. taxation, providing clarity and reassurance in dealing with their filing and reporting obligations.
My understanding of expatriate life comes from personal experience as well as professional practice. From 1992 to 2013, my wife and I lived in Portugal and France, where she taught at the University of Aveiro. During those years, I developed an international tax practice serving Americans throughout Europe and Asia.
I hold a Master's degree in Accounting with a specialization in taxation. My experience encompasses foreign pensions, investments, foreign corporations, business interests, and complex international reporting requirements.
I'm also the author of Renouncing U.S. Citizenship, a practical guide to the tax and compliance considerations associated with expatriation.
My approach is personal: I deliberately limit the number of clients I accept so that each receives individual attention, clear explanations, and the benefit of decades of international tax experience.

Experience Matters When Your Tax Affairs Cross Borders
U.S. international taxation is rarely straightforward. Foreign investments, pensions, corporations, trusts, and other financial interests can create reporting obligations extending far beyond the annual income tax return.
Barron's International Tax Service specializes in the complex filing requirements facing Americans abroad, including foreign financial asset reporting, foreign corporation disclosures, and international information returns.
Our approach is straightforward: understand your circumstances, identify your reporting obligations, and provide careful, professional guidance tailored to your needs.
U.S. Tax Filing Requirements for Americans Abroad
Americans living overseas may face extensive U.S. tax reporting obligations, even when they owe little or no U.S. income tax. Failure to meet applicable filing requirements can result in substantial penalties.
U.S. Individual Income Tax Return — Form 1040
Annual reporting of worldwide income, including foreign earnings, investments, pensions, and other income sources. Late filing or payment may result in penalties and interest.
Foreign Bank Account Report (FBAR) — FinCEN Form 114
Generally required when the combined value of reportable foreign financial accounts exceeds $10,000 at any time during the calendar year. Significant penalties may apply for noncompliance.
Foreign Financial Assets (FATCA) — Form 8938
Reporting of specified foreign financial assets when applicable thresholds are exceeded. Failure to file may result in substantial penalties, generally beginning at $10,000.
Foreign Corporations, Partnerships, and Trusts — Forms 5471, 8865, 3520, and 3520-A
Specialized reporting for certain foreign corporations, partnerships, trusts, and transactions with foreign trusts. Significant penalties may apply for failure to meet applicable requirements.
Passive Foreign Investment Companies (PFICs) — Form 8621
Reporting for certain foreign investment companies and funds, including investments commonly held by Americans living abroad.
Foreign Disregarded Entities — Form 8858
Information reporting for certain foreign disregarded entities and foreign branches. Penalties may apply in specified circumstances.
Foreign Earned Income Exclusion — Form 2555
Allows eligible taxpayers to exclude qualifying foreign earned income, subject to statutory limitations and filing requirements.
Foreign Tax Credit — Form 1116
Allows eligible taxpayers to claim credits for qualifying foreign income taxes, potentially reducing double taxation.
Reporting requirements and penalties depend on individual circumstances. Not every form applies to every taxpayer.
I was introduced to Barron Harper's International Tax Service by a friend in 2018 who is also living
abroad. Barron helped me with all the tax implications of my mother's inheritance and at the same time
helped me acquire amnesty with the IRS after being several years abroad and not having filed.
Every year I send Barron all my paperwork and he very graciously fills out the forms, answers all my
questions and submits the end product. I recently put a friend who found herself in the same situation
in touch with Barron and I've heard they are collaborating on the project.
I would wholeheartedly recommend Barron's firm again.

Throughout the past decade, Barron has consistently demonstrated deep expertise in expat tax laws, meticulous attention to detail, and absolute professionalism. He is always responsive, patient with my questions, and proactive in ensuring I maximize my deductions while staying fully compliant.

I can honestly say that I've been more than pleased with the services provided by you over the years - and especially at the time (and since) Adrian passed (away) when it was then up to me to keep the tax authorities happy. Your expert advice and guidance delivered with sympathy helped me enormously through a very difficult period. - LD
