Quotes Every year, I dread tax season, but this year I actually ENJOYED doing my taxes! I felt in good hands from the moment I had my initial 15-minute consult. For the first time, I genuinely felt in good hands with the right tax expert for my situation. I love the online portal that makes it so easy to add important docs, the communication and expectations were clear and well communicated, reminder emails are automatic and helpful...I'm 100% satisfied, will be using Greenback next year and highly recommend their services.

Quotes My tax advisor just became my personal hero. American expat friend, no matter where you live: if you are ever in need of assistance with your ever-so-complicated tax returns or FBARs, please contact Greenback! I can recommend them without reservation. My angel of a tax advisor went to great lengths and was absolutely reliable, professional, and congenial throughout. I will forever be grateful for his competent advice that finally got me back on track with American taxes.

Quotes Greenback made a complex process straightforward. I have just moved to the US from the UK and, with salaries from two jobs in two countries with different tax years, as well as rental income, I would have been lost without Greenback. They made my life easier, provided value for money and the accountant with whom I worked was helpful and happy to answer all my questions. I'll be using Greenback for my taxes next year and for many years.

Quotes I have had the folks at Greenback do my taxes for about 10 years now and have always been satisfied with the process, service, pricing, and, importantly, the results! I am one that appreciates having the same accountant do my returns over the years. This continuity is just one of the "soft" or "hard to measure" metrics in why I appreciate this service! I can highly recommend them with confidence!

Quotes Greenback is the perfect niche business. They do what they do extremely well. They are professional, responsive, and resourceful. Working with them takes the dread and tedium from that uniquely American original sin of having to pay taxes on worldwide income while living abroad. I cannot imagine facing this yearly slog without Greenback! My accountant, whom I have never met, of course, is one of my favorite people.

Quotes In 2019 I did my return with another firm because it was cheaper. But it was more stressful, the questionnaire was difficult to navigate and the advisers were impatient with my confusion. So I came back to Greenback in 2020, because I was confident it would be a stress-free experience.

Quotes Third-year in a row and I'll be back for a fourth! As a former expat now repatriated to the US, I found dealing with foreign assets to be cumbersome and increasingly fraught with risk. I selected Greenback because they are expats themselves... so they have a vested interest in understanding the evolving tax landscape and getting it right. My accountant communicates rapidly and responsively; no question ever too silly for her to answer and she is extremely diligent in follow-up and attention to detail. Taxes are almost stress-free!

The Owners

After being frustrated and overwhelmed with their own expat tax needs, Carrie and David decided to build a service that could meet the needs of US expats — a tax preparation company whose accountants were at the forefront of expertise in US expat taxes, that was simple and easy to work with, and treated customers fairly and respectfully.

Carrie is a long-term expat, travel lover and seasoned business professional who believes that filing taxes doesn’t have to be a grueling process. Originally from New York, Carrie was raised in Mexico City, and has since lived in Barcelona, London, Montevideo, Rio De Janeiro, Buenos Aires, Bali, and now Costa Rica. Carrie has a BA from Columbia University and an MBA from International Business School IESE, followed by 15+ years in marketing and general management. Carrie and her husband and co-founder David started Greenback after struggling to find a firm to do their US taxes as Americans living in the UK.

As CEO, Carrie spends her days ensuring that Greenback offers exactly what US expats need: easy-to-use, professional American tax services that delight our customers worldwide.

David is an Enrolled Agent, an MBA, and an experienced finance professional and entrepreneur. Having grown up in Brooklyn, New York, David caught the travel bug after an exchange program in Belgium. Since then, he has lived all over the world. Year after year, David and his wife Carrie found that filing their expat taxes was a nightmare: expensive accountants who treated them like a number, US CPAs who were well-meaning, but not up to date on the rules as they apply to expats, and lots of forms and calculations. It was while living in London that the idea for Greenback Expat Tax Services came to be. At last, the dream of hassle-free expat taxes became reality.

As co-founder, Dave helps lead Greenback’s public relations efforts, advocating worldwide for a deeper understanding of expats’ unique tax needs.
