Once you understand how to access and move within the “back office” portal, where all documents for each year are stored, it is very easy to work with the Greenback tax portal. Well set up. Easy also to alert Daria via email that there was a document uploaded on the portal so no tax related documents were missed or overlooked inadvertently. Love the review of tax return process. Very easy now to be able to virtually sign for FBAR and tax return and then pay IRS what is owed. Great then that Daria alerted us by email when the tax return had been accepted by the IRS and where this year’s documents were stored on the Greenback tax portal. The tax prep process, start to finish, has now become very easily accessible, easy to work through, and at the end closure is achieved. Until I became an expat 5 years ago, I would never have expected for the tax prep process to be so easily adapted to a virtual experience as I always for over 40 years had always done my taxes with an actual person in their office. Greenback has totally changed my opinion on how taxes can be done and how headache free the process, start to finish, can be. I will never use any other tax preparer for my future expat taxes. Thank you Greenback Team!

As an American living in Austria, I didn’t know I have to file FBAR together with my tax returns until an American friend told me. I search the internet and finally decided on Greenback Tax Services because of the good reviews and upfront services fee on the website. Received email from Ms. Tabitha who connected me to Ms Yasmin Madhani, who were professional, friendly and patient in helping and guiding me to finish Streamline Offshore Program. She answered all my worries, questions and even working on her weekends on my tax. I am happy with Ms Yasmin, Ms Jessica Legan who helped in getting ITIN for my wife and Ms. Tabitha for their great services and we will continue to work with Ms Yasmin and Greenback Tax Services for our future tax return

Sylvia B - Switzerland - ★ ★ ★ ★ ★ 5 out of 5 stars

First year customer and very impressed with constant e-mails communications with CPA on line. Simple and smooth. Highly satisfied with Federal and State taxes return results. Final invoice due price, moderate. I will definitely use Greenback Expat Tax Services next year.

I have been working with Christina for a few years. She has made the process easier to understand. She always has an answer, except when she doesn’t and then she finds out. I have used other accountants in the past and they seemed to have an aversion to learning. Not Christina. She is also always there for me when I need an answer.

We are a returning customer and happy to have Greenback Tax as a help for the tax matter. This year John did an outstanding great work.
Hope he will help again next year.
If you have any question or concerns Tabitha responds quickly.

Sylvia B - Switzerland - ★ ★ ★ ★ ★ 5 out of 5 stars

I’m a US taxpayer and have lived and worked in the UK and Hong Kong over the last 10 years. About 6 years ago, I was worried about making sure my taxes were being handled correctly. I had been doing it myself, but it became too complicated and time consuming. I’m grateful for the excellent service provided by Greenback taxes, and especially my advisor Daria Prohorenko. Daria is one of the best advisors I’ve come across. She is extremely knowledgeable, and always gives our questions a thoughtful and useful response. I always have complete confidence in her advice. The entrepreneurial business model of Greenback is also a big plus – it provides access to world class professionals at very compelling value (especially compared with using a big 4 firm). I would recommend Daria and Greenback without reservations to any US taxpayer living abroad. Thank you for all your help over the years!

Peter M - Hong Kong - ★ ★ ★ ★ ★ 5 out of 5 stars

We started using Greenback when we moved to the UK for 2 years with my company. Nick Smith was our accountant and we were so grateful for his help year after year. I should note, that as part of my relocation package, I was provided with “tax advice” UK by a large accounting firm. After the first year I was very disappointed. They were hard to get a hold of, didn’t ever answer questions, and were tedious to work with. I never understood anything the way they explained it. So the next year, I also used Nick – meaning, I paid out of pocket when I didn’t have to – to use Greenback because my husband had had such a great experience. And I did too! Nick was a pleasure to work with. Responsive, friendly, and the best part – I understood everything he told us. He made taxes easy to understand! I recommend Greenback to anyone I know who is an expat and will continue to do so based on the experience I had! Thank you!

I have a rather unusual and complicated tax situation. For years I have struggled to find professionals who understood or were able to help me. Greenback truly made it all seem so straight forward and stress free. The communication was excellent and the transparent and timely process was very reassuring. I wish I had come by them years ago. They would have saved me so much money, confusion, stress and time. I will definitely be a returning and regular client.

Scott S - United States - ★ ★ ★ ★ ★ 5 out of 5 stars

Excellent service, timely response, and looks after the interests of the customer. Will be back next year.

I am extremely please with Greenback’s services. Highly professional and high touch preparation. No more PWC in my life!

ROBERT M - Switzerland - ★ ★ ★ ★ ★ 5 out of 5 stars

I am incredibly impressed with the efficiency, professionalism, quality of service, and knowledge of your tax professional, Yasmin Madhadi. I have been struggling with both H&R Block, and an independent tax professional for the last 15 years, who just didn’t understand the basics of how to file taxes for an American living abroad. Minutes after finding the website and signing up online, I was delighted to receive an email to my inquiry from Yasmin-on a weekend! She quickly answered my questions and calmed my fears regarding qualification for the Bonafide Resident Test and pulled together three years of tax returns for me in no time. Additionally, she found that it is completely unnecessary for me to file state tax returns (H&R Block charged me nearly $150 a year extra to file them), and even wrote up a letter on my behalf to send to my state revenue authority,informing them of this.

Yasmin’s services are first-rate. This is hands-down the best service I have ever used for tax preparation. I have already passed Greenback Expat Tax Services’ information to the 200 plus foreign staff who work with me in Kenya and South Africa and am happy to share on the foreigner social media groups in Nairobi.

Lauren M - Kenya - ★ ★ ★ ★ ★ 5 out of 5 stars

I have been very impressed with the professionalism, knowledge and work ethic that Greenback’s accountants offer. Nick Smith not only made the process of filing a UK tax return painless and hassle-free, but he also did so on a very short notice. I’m glad I finally found an accountant who takes the pain of tax returns away and I can wholeheartedly recommend his advice!

Stef G - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

Awesome! As an American Living in the UK, the thought of managing so many nuances of international taxation drove me to tears. Luckily Nick Smith and Gabriella Worrell really took good care of me quickly and efficiently. I am so very pleased with the efficient, thoughtful, and dedicated service I received. It feels personalised yet efficient. I am 100% satisfied and will be coming back to Greenback for years to come! No doubt I will be recommending Greenback for my fellow expats! Well done and keep up the great work. This is truly a great company with great people. Many thanks!

Mark F - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

Nick Smith did a great job with my UK taxes, answering all emails promptly and clearly answering any questions I had. Reasonable rates and little effort needed on my part.

Michael B - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

As we draw to a close, I would like to say that I am very satisfied with the overall result and want to personally thank Daria Prohorenko for her meticulous attention to detail, her clear and concise explanations and most importantly for her enduring patience. Daria is the consummate professional and her excellent work is very much appreciated!


arne l - Sweden - ★ ★ ★ ★ ★ 5 out of 5 stars

Wow. Greenback have been the most responsive service I have used in quite a while. From the moment I shared what I thought was a very intricate set of circumstances, Nick was able to confidently and enthusiastically take charge of the situation and explain everything in a clear and executable manner. In the end I will end up earning money from having worked with Greenback to help understand the relationship between bother my US and UK tax returns. Very easy decision to go with them again in the future. Thank you.

Ryan H - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

The idea of dealing with US tax (after 30 years blissfully unaware that I was even supposed to file!), had taken on dread proportions in my mind. However, once I engaged with Greenback, I found the whole process was a breeze. One or two things to look up, but no 3rd Degree. Thank you for making it painless!

Ian S - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

You asked me all of the questions very clearly, gave me easy forms to fill in, made sure that I did everything correctly, and sent it off. The bill was small compared to a hack accountant I spent months and over $2000.00 only to have him tell me he can’t finish it! What a relief to know that I am starting early with you this year!

Catherine C - Cayman Islands - ★ ★ ★ ★ ★ 5 out of 5 stars

I was behind in filing my USA taxes. Greenback was recommended by a friend in Australia as an alternative to tax services by a Big 4 Accounting firm. It was so easy to sign up with Greenback and the accountant assigned was responsive and knowledgeable and helped me understand what info provide. In a few months, all the forms needed to get my USA taxes up to date were prepared and submitted … and the fee was a fraction of the cost of the Big 4 Firm. I am a very happy Greenback customer!

Sally D - Australia - ★ ★ ★ ★ ★ 5 out of 5 stars

For US Ex-Pats living permanently overseas it is extremely important that the Accountant fully understands all the unique reporting requirements. John Ramdeen is the first Accountant we have come across that does appear to have the knowledge, we had had to do some serious amended re-filing to correct our reporting over the last 5 years.

David B - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

I had a wonderful experience working with Greenback tax services and highly recommend them for anyone who needs to use ex-pat tax services.
Please use my name as a reference for future prospective clients…

bruce l - Belize - ★ ★ ★ ★ ★ 5 out of 5 stars

Our tax situation is pretty complex and Elizabeth did a great job of helping me understand the way that US and Australian taxes affect eachother. She also helped me answer quite a few questions that were not directly related to our returns, including doing quite a bit of extra research. Thanks and well done!

Mark B - Australia - ★ ★ ★ ★ ★ 5 out of 5 stars

I have been procrastinating filing, anticipating it would be time consuming and a hassle. After one email with Greenback I was given easy step by step instructions and in no time at all I was finished and completely relieved and satisfied with the whole process. Thanks a bunch Greenback!

Monique M - Sweden - ★ ★ ★ ★ ★ 5 out of 5 stars

Moving overseas for the first time has been an enthralling adventure! However, knowing how to handle my taxes in consideration of said move was totally daunting. Thankfully the experts at Greenback are geniuses and all I had to do was give them the dates and the numbers, and wala! My taxes are done. Grateful to have this team on my team!

Willo O - Hong Kong - ★ ★ ★ ★ ★ 5 out of 5 stars

I am completely comfortable working with Christina and Greenback . I consider myself a complicated challenging case and Tina went the extra mile and was always supportive and reassuring , while guiding me . I will be working with her from here on out ! THANKS !

Haywood H - Mexico - ★ ★ ★ ★ ★ 5 out of 5 stars

An excellent experience, from start to finish. Daria was unbelievably professional and courteous even with my long gaps of no contact due to travel.

Thomas F - Hong Kong - ★ ★ ★ ★ ★ 5 out of 5 stars

Marina did a wonderful job on my taxes. I am very confident in Greenback based on my experience with her. She is fast, efficient, knowledgeable, and probably really cute (not sure on that part). I hadn’t filed for a while and she got me squared away with little hassle.

David F - Thailand - ★ ★ ★ ★ ★ 5 out of 5 stars

Greenback completely removes the anxiety and the work involved with filing US taxes as an ex-pat. Their team not only understands the complicated US tax law, but also the crucial details of US tax treaties with other countries. Worth every penny spent!

Robert P - Switzerland - ★ ★ ★ ★ ★ 5 out of 5 stars

If you felt lost when it comes to successful real estate investment in the US, the Greenback Tax Accountants will not only show you the correct way, but will also give you good guidance to avoid myriads of traps.

Apares C - Australia - ★ ★ ★ ★ ★ 5 out of 5 stars

This was my first time using Greenback and my first time filing xpat taxes. I am a dual Canadian/American citizen and have pensions, income, and investments from both countries. I feel my situation is fairly complicated. With all the new stuff from the US and everything else I felt very comfortable and safe with the services provided by Greenback. They also found some lost money from previous returns!!

Gregory M - Qatar - ★ ★ ★ ★ ★ 5 out of 5 stars

With Nick Smith walking my husband and I through our UK tax returns and Masako Hirose on the US side we feel that we are in very good hands! Paying taxes in two countries is a bleak task, but Nick and Masako have made the process as seamless as possible for us. They are efficient, knowledgeable and most importantly kind. I recommend Greenback – and specifically Nick and Masako – to other expats.

Linda S - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

I’m a dual citizen of the US and UK, and have been living in England for several years now. Being a self-employed business owner and taxpayer here in Britain, it never occurred to me that I needed to file US tax returns until someone recently told me. Just the thought of pulling all that paperwork together put me into serious overwhelm! But Tom at Greenback was an absolute dream to work with. He moved slowly and systematically through everything. He asked lots of questions, and answered even more of them. And NEVER ONCE did I feel overwhelmed or confused. Within two weeks, we filed all the paperwork that brought me 100% up to date with the US tax department. I cannot tell you how relieved I am to finally be compliant! I will be using Greenback every year from this point forward. Easy, stress-free, competent, friendly, polite and HUMAN. They definitely get my 5-star rating.

Lynn S - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

Excellent service and results! Absolutely “painless” experience. I know all you expats out there understand what I’m saying with how complicated our taxes can get. All I had to do was provide the info Marina asked for and a couple more emails from her confirming the info and a few more questions and I just kicked back and she did all the work. I received two returns that ended up being very substantial. Thank you Marina and Greenback for the very professional yet personal service! I will definitely be a return customer and highly recommend your service!

Art S - United States - ★ ★ ★ ★ ★ 5 out of 5 stars

Nick was incredibly quick, clear, and helpful in preparing my UK taxes. Thank you for making a dreaded task one I could quickly tick off with a smile!

Jenna H - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

My tax preparation process was very smooth and efficient. I was very pleased with the communication, knowledge and professionalism of my accountant. I will definitely use Greenback again next year!

Sean L - Switzerland - ★ ★ ★ ★ ★ 5 out of 5 stars

The US tax system is nearly impossible to comply with unless you have competent accountant assistance. I am happy with the services I have received from Greenback Tax Services these past five years, including getting me current on my filings. I would suggest completing the FBAR yourself if after viewing the document you think you have the time and capacity to do so, as I found it annoying and evasive but not hard.

Chris J - Australia - ★ ★ ★ ★ 4 out of 5 stars

The process of completing my returns was not without hiccups, but the professional and meanwhile personal response to any of my queries from David and Tabitha, and from Erin (who took over my account for the home stretch) convinced me that this is an organisation that is committed to providing a service of a very high standard. I will return year after year without hesitation, and have recommended Greenback to American friends here in Hungary as well as in other countries.

Steve O - Hungary - ★ ★ ★ ★ 4 out of 5 stars

Nick Smith is an absolute pleasure to work with. My tax situation was especially complicated this year. He patiently and diligently guided me through the whole process while doing all the hard work in the background. I can’t recommend his services highly enough. Worth every pence!

Brian P - South Africa - ★ ★ ★ ★ ★ 5 out of 5 stars

Lauren did a great job with my tax return again this year, and really pulled out the stops to help meet a personal deadline before the return was officially due. She’s great to work with; I highly recommend her and the Greenback team!

Mike J - Australia - ★ ★ ★ ★ ★ 5 out of 5 stars

Jessica does an awesome job of completing the returns – she is super responsive, professional and thorough. I have confidence that she is providing the right advice and will work with me to get it right. She is onto every deadline and I knew I was always in good hands.

David H - Australia - ★ ★ ★ ★ ★ 5 out of 5 stars

SUPER! Nick Smith and April G are a dream team – supremely responsive, diligent, and on top of things. I feel very well taken care of….as an American expat in London for a while now, I finally feel as if I found a company which understands my particular challenges and offers the best advice I can get. Would highly recommend them!

Jamie P - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

As a professional photographer I traveled extensively before finally moving abroad full time. The whole time I was in the US I did my own taxes using Turbo Taxes, but when I decided to move abroad I wasn’t sure I could continue doing things this way. I got in touch with Greenback and quickly realized that they were the tax experts, not me! They helped guide me through the process of qualifying as an expat, filing for that first year abroad and for each year since. Thanks Greenback!

Tommy S - Indonesia - ★ ★ ★ ★ ★ 5 out of 5 stars

I have never been so wonderfully taken care of for any service for which I’ve paid than with Greenback Tax Services! From the moment I registered until after my taxes were prepared and filed, the level of service was superb. I was informed every step of the way, provided various methods of communication, a secured file repository, and basically provided everything on a silver platter so that my taxes could be taken care of in a timely manner. There were no stacks of repetitive forms to fill out, no legalese, and no leaving me guessing. I heartily recommend Greenback Tax Services to anyone abroad that needs assistance in getting their taxes filed properly and in a timely manner.

Brian T - Norway - ★ ★ ★ ★ ★ 5 out of 5 stars

Greenback are very professional in their approach and task completion with responses being completed many times in “out of hours” together with quick follow ups and explanation which go “above and beyond” on a number of occasions. Highly recommended

Arthur H - Australia - ★ ★ ★ ★ 4 out of 5 stars

I strongly recommend Greenback! I’ve used other preparers in the past and none have matched the ease of submitting my information and complete, professional preparation. All at a fraction of the cost. Exceptionally well done!!

David M - United Kingdom - ★ ★ ★ ★ ★ 5 out of 5 stars

I am an entrepreneur and my main focus is making my business the best it can be. I had fallen behind on my US taxes and that’s when I engaged Greenback. The process was simple and smooth – I uploaded my tax records, the questionnaire and then my accountant prepared and filed my returns. Now I can stay focused on my business knowing that Greenback will take care of my US taxes!

Dan A - Vietnam - ★ ★ ★ ★ ★ 5 out of 5 stars

Tax returns overwhelm me, to say the least, but this is my 3rd year using GBT for my US taxes and it makes the process so much easier, and keeps me confident that nothing will get overlooked. I was nervous when our GBT accountant changed hands last year, but Daria picked up right where Tim left off seamlessly. If only GBT could do my Australian taxes too!

Kristin R - Australia - ★ ★ ★ ★ ★ 5 out of 5 stars

I had given up on filing for 2014. It just seemed too complicated with 2 countries, filing jointly, 3 kids, going only from pay stubs. Jeremiah worked with the documents I managed to pull together at the last minute. Not only did he crunch the numbers for a refund, but now he is going back to investigate some past returns to see if we could have received refunds in years past.
