The whole process was easy

The whole process was easy and facilitated from A to Z by my accountant. And it cost me a lot less than my US CPA. I chose the complete help package and they did everything for me.

Excellent experience

I was skeptical at first, but Krishna Nataraj was extremely responsive and helpful. He understood my situation and was able to answer all my questions. He prepared my returns quickly and for a very reasonable price (1/4 of what I paid last year). It was a great experience.

Expert personnel

I have been with the same accountant from Greenback Tax Services for 11 years. No complaints. Seems to work all hours as response to any questions rapidly forthcoming despite the 8 hour time differ

Most reliable

After using Greenback several years, they have proven to be consistently efficient, reliable and responsive. Their portal is easy to understand and complete for tax relevant tax information. I would absolutely recommend Greenback to any expat for their tax filings.

Greenback and Pablo are Number One !

I can't say enough about Greenback and my accountant Pablo Valle. He is professional and courteous and takes the time to understand my personal situation. He is extremely detail oriented and always has time to answer my questions with easy to understand explanations. He is very responsive and always provides solid actionable advice for what I can do in the future to reduce my tax burden.

Efficient, prompt and professional service

This year, as in several years in the past, Greenback was efficient, prompt, and professional. My accountant, Mrs D Smith, is superb, responding to queries quickly, helpfully, and courteously. I give her and Greenback my highest recommendation.

I was overwhelmed with trying to figure…

I was overwhelmed with trying to figure how to account for a foreign pension on my US taxes. Greenback had a page on their site that directly referenced my case, so I took the leap. My accountant, Nisha, was extremely knowledgeable and very patient as she led me through the process. It was a huge leap of faith for me, and I am so happy to have had a perfect experience!

How to Sleep Worry-Free

Living overseas and trying to navigate the sometimes turbulent tax flow that engenders can cause sleepless nights and shrinking bank balances without professional assistance. Thus the relief and heart-and-wallet felt appreciation when the Greenback team, led by the incomparable D. Smith, arrives to save me again. Arigatoooo from Japan!

Expert, responsive guidance for tax filing

I have had an outstanding experience working with this Accounting firm during the current tax filing year. Our Accountant, Melvin consistently provided prompt service and quick, thorough feedback whenever questions arose. What truly sets Melvin, and this firm apart, is their deep knowledge and ability to clearly explain advanced tax concepts. They offered thoughtful guidance on complex matters, ensuring that everything was handled accurately and strategically. Their expertise gave me confidence that my filings were not only compliant, but optimized for my situation. I highly recommend this firm to anyone seeking responsive service, technical proficiency, and reliable support throughout the tax process.

Greenback's service was excellent

Greenback's service was excellent. I have worked overseas for 37 years and thus my employers provided tax services each year. I recently retired overseas and needed help since I had some complications and had not prepared a tax return in nearly 40 years. The service was professional and fast. The tax return will be a bit less complicated next year but I suspect I will use their service again to ensure everything is prepared quickly and accurately.

Highly recommended, especially April G

I worked with Greenback Expat Tax Services for several years while living abroad. My situation was not easy as a self-employed worker with several sources of international income, but Greenback's accountants were always knowledegable and easy to work with. I was especially pleased with the assitance of April G, my accountant for the last couple of years. She is truly an expert and a professional in every sense, I highly recommend working with her.

I moved back to the US and will not be needing their services anymore, but if I move abroad in the future I would hire Greenback again without thinking twice about it.

Fast turnaround and detailed service

We can’t say enough good things about Jorge Diaz. He’s been an incredible accountant to work with and has made things that once felt complicated feel simple and manageable.

He’s always super quick to respond, extremely thorough, and never leaves questions unanswered. Non-resident taxes can be tricky, but Jorge handles them with ease and confidence—far better than any accountant we’ve worked with before.

What we appreciate most is how clearly he explains everything whenever we need it. It gives us real peace of mind knowing we’re in good hands. Highly recommend Jorge to anyone looking for a reliable, knowledgeable, and genuinely helpful accountant.

Efficient and responsive

Takes the stress out of navigating complicated tax systems as dual citizens. Our tax returns have been completed quickly. Our accountant is easy to work with, responds in a very timely manner to our questions, and gets the job done.
