Greenback Expat Tax Services Reviews 

I have been using Greenback for almost a decade now. Their systems are easy to use and the handover to a real tax expert is seamless. I've had the same accountant since the start, and she is incredible. She knows our situation, asks great follow-up questions, and gets the returns filed quickly, efficiently, and accurately. The cost are reasonable and forward planning for tax mimization good. Great company and I will be using them going forward. Craig - Business owner in Australia

This is my first time using the help and expertise of Greenback. After using other companies for many years, I can comfortably say with confidence that Greenback is one of the best. They are a bit expensive, but it is well worth it. Thank you!

I have been working with Greenback Tax Services and my accountant, Nilanjana Sinha, for the past three years, and I could not be happier with the experience. From day one, the process has been smooth, professional, and completely stress-free.

What truly sets Nilanjana apart is her expertise, attention to detail, and proactive approach. During a recent review of my tax situation, she identified significant tax-saving opportunities that had previously been overlooked. Thanks to her thorough analysis, I was able to file an amended return and receive a substantial refund that I would have otherwise missed.

As an expatriate taxpayer, navigating tax regulations can be complicated, but Nilanjana consistently makes everything easy to understand and manage. She is highly responsive, patient with questions, and always takes the time to explain options and recommendations clearly.

Greenback Tax Services has provided excellent support throughout the years, but Nilanjana's dedication and professionalism have made the biggest difference. It is rare to find an accountant who combines technical expertise with such outstanding client service.

I highly recommend Greenback Tax Services and especially Nilanjana Sinha to anyone looking for knowledgeable, trustworthy, and proactive tax assistance. Their service has delivered real value and complete peace of mind.

Super stars in customer service with clear and competitive pricing. They are professional and timely. I highly recommend them for taxes, especially when it comes to navigating my complicated expat situation. Nijil is trustworthy and friendly, and I will continue to go back year after year. Thank you!

As a self-employed expat - I have trusted Greenback with my taxes for the past 3 years and I've actually enjoyed the experience. Knowing someone has my back and is there for questions and helping me understand how the system works is super valuable.

Greenback Taxes has a team of highly experienced CPAs who work with American expats and non-us citizens who owe U.S. taxes. It's important to have accountants who understand tax preparation for the unique needs of an expat, and I'm always happy to recommend a good company when I find one.

I worked with Marina, who was detail-oriented, communicative, and responsive. I appreciated her clear guidance throughout the tax filing process.

I had a great experience working with Greenback. They were fast and convenient. The accountant answered all of my questions promptly.

I worked with Greenback on my 2025 US and DC tax filings, which involved a substantial and complex cross-border transaction. While the return may ultimately be technically correct, the process raised serious concerns about communication, judgment, and overall ownership.

Despite the size of the tax liability, I was advised that filing by April 15 was not necessary, without a clear explanation of the risks or potential penalties. This was particularly concerning given that tax is still due by April 15 regardless of the filing extension. As a result, I am now facing interest and penalties that could likely have been mitigated with more proactive handling.

I was also urged to make an extension payment of approximately $140,000 based on an initial draft. However, this estimate was provided before my full cost basis and capital improvement data had been incorporated into the calculation. I requested a detailed breakdown of the estimate (including gain, depreciation recapture, and tax rates), but this was not provided at the time. The estimate was later revised to approximately $112,000. A discrepancy of this magnitude should have been clearly explained before recommending that a client move significant funds.

In addition, I identified a material issue in the draft return related to the treatment of foreign taxes on a large capital gain. The return initially did not appear to properly reflect the foreign tax credit, creating a risk of double taxation. I had to request a senior-level review to have this addressed, rather than this being caught as part of the normal preparation process.

There were also other oversights, including the handling of the DC filing requirement, which added further uncertainty.

Throughout the process, I repeatedly requested timely action and clarity on next steps. Despite this, key steps were delayed until the final day, resulting in a compressed filing process and unnecessary stress.

There were also inconsistencies in the filing instructions provided. For example, I was instructed to sign a page of the DC return that does not actually contain a signature block.

Overall, my experience highlighted issues with communication, transparency, quality control, and ownership of the process. These are critical in complex, high-value tax matters and, in this case, required significant follow-up and intervention on my part.

Marina was excellent. She was patient, answered my questions, and was very responsive & thorough. I felt very taken care of from Day 1.

Good, professional. attentive service.

I have been using Greenback for my US foreign taxpayer obligations for five years. They have consistently made the ominous activity of completing US tax reporting requirements as easy and less burdensome on me as possible. Everyone has unique or complex issues and they handle them quickly and efficiently without throwing any additional burden back onto me. The entire process involves completing a simple questionnaire, sending a copy of your final foreign tax return (with brief translations where needed), supporting documents like 1099’s and W2’s and that’s all. Then in a week or so your done, electronically sign your return and they do the filing and keep you informed of the process. That’s it, simple and fast with no frustration or anxiety.

Greenback really is worth it! I've been working with the same accountant for the past five years. She's responsive and efficient. She's attentive to detail and really keeps up with changes in the tax code -- it's so complicated and it changes all the time. She gives me peace of mind -- I'm so grateful for the service they provide!

Stumbled upon Greenback 3 years ago as I was looking for tax solutions for my unique situation. Nisha James has been our tax expert since 2023 and she has been doing a fantastic job! She is thorough, knowledgeable and patient. We have had a good experience with her all these years and hope to continue.

Ms Sudhakar is organized and meticulous. In addition to the usual accountant-side tasks, she kept me focused on completing my share of the work without being overly pushy when following up. Most importantly, she addressed my confusions and uncertainties both clearly and succinctly.

I could not ask for a better experience with an online-only business relationship.

The Agent was reasonably responsive, although I wish the Agent would confirm receipt of my messages a bit more promptly. I also felt an unnecessary pressure with upselling (need for completing additional Schedules); especially so since I am a finance professional. Knowledge of the Indian landscape such as familiarity with the Indian Tax Return and matters like flexi deposits was lacking. Overall, satisfied with the service level.

Thanks so much to Greenback and Harsh for making this tax season easy and pain-free. This was our first time using Greenback and we will definitely be repeat customers!

Rakhy was excellent. We had an initial consultation before I moved from the U.S., and I was pleased she was available to do my return for me. She answered my questions and was careful throughout. Some responses could take time, but I was working with her at a busy time in March and April. The price was fair, too.

Nisha James is a wonderful accountant to work with. She's knowledgeable, quick to respond, and the process is super smooth.

Very professional and whole process was very straight forward adn easy. Recommend to anyone has needs help with EXPAT taxes
