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.

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.
