Mike has been very helpful and his team has been extremely accommodating. Mike has greatly helped in correcting all of my previous incorrect filings and calculations.

And because of this I would be able to receive a total of $35k+ USD tax refund for the amended tax return. He gave very instructive advises and information that were essential to what I needed. I highly recommend Mike and his team, I have no doubt that he would be able to assist and help any US expats seeking aid and assistance in filing their US taxes.

Working with Mike was a breeze and productive. He crafted amendments for 2013-2014 to move Foreign Taxes carryovers to 2015, saving me 30K+ USD in year 2015.

Mike is a terrific tax professional who brings a wealth of expertise to everything he does. I highly recommend Mike for the services and knowledge that he brings to the table.

Also like the fact he is dedicated to his profession and takes continuing education as serious as he does.

Last year I asked Mike to take over my tax return preparations, and based on his advice we filed amended prior years’ federal tax returns from which I received over $19,000 in refunds.

He knows how to deal with the IRS, and is very knowledgeable about federal and state income tax compliance, as well as tax accounting. He has been extremely helpful throughout the process; specifically in his guidance navigating the federal and state tax laws.

I would recommend Mike without any hesitation.

I have enjoyed working with Mike who has helped me prepare not only this year’s taxes, but also the past 3 years of both my US federal and Massachusetts state taxes.

He and his team are very knowledgeable in both returns, especially considering some of the complexities of offshore accounts and onshore investments in standard brokerage accounts as well as real estate. He has managed to save me ~$7K+ USD on federal taxes and $2K+ USD (MA State) taxes after amending my 2013-2015 tax returns. Not only is the money being saved an obviously massive perk but the time I am able to save and overall confidence in “getting it right” has also been a huge save.

Mike is wonderful to work with, dedicated to helping his clients, organized, efficient and very easy to communicate with. I would highly recommend Mike and I am looking forward to a long-term relationship with him. Thanks Mike!

Michael is very helpful in preparing all of my taxes and dealing with the IRS directly to make sure I didn't have to pay undue fees.

He also helped advise on the optimal tax structure for me as an expat in Asia as well. I would recommend Michael for other expats.

Michael A. Mertz has been my CPA for several years and he is a thorough, smart, and trustworthy advisor and accountant. Having been self-employed for many years and living overseas, I have a complicated tax situation.

On a regular basis, he helps guide me through the process of organizing my finances and filing my taxes on my behalf.He assists with my tax planning as well. His work as a CPA is impeccable. His character and professionalism make him the best accountant I have worked with, and his work is first rate. I highly recommend him.

Michael A Mertz, CPA approached me on Linked In in order to help me get caught up on my US taxes. He prepped 3 years for me and the result was very satisfactory. I was amazed how easy and efficient the entire process was…

The process from NDA’s to Engagement Letter to Skype consultation to a in person meeting in Tokyo was very smooth and easy. I would recommend to use him for your US tax prep and any other tax-related or accounting questions.

Feel free to talk to me if you would like an in-person recommendation. Anything I can do to help others to learn more about the service and level of professionalism they will receive from Michael is the least I can do based on the great experience I had.

Michael is an expert on US Expat taxes. I have used his services as well as recommended him to friends with situations significantly more complicated than mine – all to satisfactory results and money saved.

While Michael is not the least expensive option available in terms of the preparation itself, I believe he has greater value for the money than other options when it comes to general peace of mind, money saved on the taxes itself, as well as professionalism/his vast knowledge of the subject.

Additionally, I highly appreciatehis firm's use of a secure, cloud-based document centre to upload my sensitive information, instead of relying on email or other solutions like other companies. That they invested in my data security to build such a portal is no small thing to me, and one more reason why I recommend his service over others.

Mertz-International LLC has been my tax consultant since 2009. In this time, he has accurately prepared my US tax returns and provided relevant and timely answers to any and all tax questions asked.

I have been an expatriate living in Europe since 1998 and have worked with several "big name" accounting firms and tax consultants in this time. The quality of the results that I have received from Mertz-International LLC is equal to what I have received from other providers, the service is more personal and the value for money is better.

I endorse Mertz-International LLC as a quality provider of US expatriate tax services.

Michael helped me meet my US tax obligations as an expat; he patiently explained the process and helped me prepare my returns.

He is a very knowledgeable, service orientated and friendly tax expert. I will gladly continue to work with Michael and I’m pleased to recommend his professional services to anyone.

Mike is truly passionate about what he does. I've never met someone so smart about all thing financial in all my life. I've been a client of Mike's for more than 7 years now. Mertz-International has been handling my taxes since 2012 and my companies' finances as well.

Mike has worked personally with me and always goes above and beyond to make sure I have all areas of my financial life in place regarding insurance, wills, investments, tax planning etc which has made a difference in my financial life as I'm not very good about those things.

It's not just Michael, his whole team is great. They are really proactive, accommodating and a pleasure to work with. It really gives me the peace of mind to know that I entrusted this work to the right company. He is an important partner in my business. I always recommend the services of Mertz-International and Michael to other business owners.

As a first time expat taxpayer, Michael and his team made the process of filing this year as seamless as possible. They have done a wonderful job and made me feel at ease during each step of the filing process, ensuring that there was open communication and that I received the best care possible- including sound financial advice.

I was impressed with their professionalism, how detail oriented they were with my account, and their efforts to change the structure of my returns so that I might take an IRA deduction.

Thank you for your efforts and time. I will definitely entrust the filing of my 2020 taxes as well. Highly recommend to my fellow expats to the services of Mertz International!

I just wanted to share a quick note and let you know that you guys did a really good job. Searching for a competent and professional tax service has always been difficult for me in Asia.

It was extremely important that I catch up on my taxesand I feel relieved that we are nearing a conclusion of what had previously been difficult and time-intensive to accomplish. Thank you all very much for your help to finish my taxes for past years.

Michael and his team far exceeded my expectations! I’ll definitely look forward to sticking with your team and recommending your services on streamlined offshore tax filing and other services to my friends in China!

I have been a client of Michael since 2018. I had issues with my prior tax returns and needed help. I can't thank Michael and his team enough for the advice and work that saved me from future problems and potential penalties.His advice has helped me to get the most benefits from my filing.

The process that Mertz International Limited provided for filing my income tax return was very convenient and easy to follow. I was pleased with my first year of work with them and decided to have my 2019 tax return be prepared by them as well. Definitely a recommended service for expatriates looking for a US tax expert overseas.

Mike and his team were great. It was my first time to work with them this year (2020), and they did not disappoint. I am fully satisfied with how they handled my tax return. All I had to do was provide the necessary documents they are requesting.

Best thing is I get to contact Mike directly for advice and talk to him about my concerns.

I would definitely recommend the tax preparation services of Mertz International Limited to my fellow expats.

Mike Mertz has been doing my taxes for 4 years now and I couldn’t be happier. We were on the same softball team in Shanghai, I had known him for a couple of years before I got involved with the tax stuff. I reached out to him when I couldn’t find someone in the States that knew how to handle looking at Chinese W2s and year-end tax reports.

Mike has built a decent sized business helping people that work abroad and I have had a great experience working with him. He was able to get the US to refund all of the taxes I paid to the Chinese government, even going back to my first year – 2006. He handled all of the financials surrounding my relocation in 2012 as well as when my wife moved to the US last year and had to bring all of her assets. It was complicated but we made it work and I really couldn’t have done it so cheaply without him.

Anyway, he is a great person to work with, it’s very simple to upload docs to his site and he knows everything there is to know about the special tax requirements of expats. He would make your financial stuff a breeze.

Michael was the most detailed-knowledgable CFO I have had the privilege to work with.

Multi-tasked and possessed the business logic hat that is very difficult to find in the financial field.

His talent is unique.

I've fallen behind in my USA taxes for quite a few years and needed to renew my US passport. I wanted to make sure that my US tax obligations were up to date before renewing my passport.

Michael patiently explained the process and helped my by preparing multiple years (8) for me. He was very helpful and I plan to use him to file my 2011 taxes in 2012 now that I am completely caught up through 2010.

I have also recommended him to many of my friends either with similar situation as mine, or are looking for a professional/trust-worthy accountant abroad.

Michael is an excellent resource for tax preparation. He patiently explained the process to me, made sure I understood each step, gave great advice, and then did my taxes in record time.

I enthusiastically recommend Michael as a tax accountant for expats and look forward to continuing to hire him in the future.

I have known Mike Mertz personally and professionally for approximately 2 years. Mertz-International helped me to amend and file 3 years of tax filings and bring my tax situation current.

The services I received were professional and to my satisfaction. Mertz- International calculated and corrected all the “foreign tax credit carryovers” and helped me step-by-step to resolve my filing status. I continue to entrust Mertz-International for all my taxation matters and confidently recommend this company to other expatriates in need of similar services.

Based on my personal experience, I can attest that Mertz-International is committed to holding the highest levels of integrity in providing professional tax services.

As an expat for the last 15 years, based primarily in the Russian Federation and working for various multinational and local companies, my US tax reporting became incrementally more intricate and complex to manage.Mr. Mertz's own international experience coupled with his financial background and expertise gave me the necessary confidence to entrust my financial matters to Mertz International LLC (ML LLC).

The services I received were much to my satisfaction, as all the perceived intricacies were shortly clarified and the multiple steps taken to resolve my filing status were clearly and effectively communicated by Mr. Mertz, and subsequently executed to successful closure. To this end, I continue to entrust my taxation matters to ML LLC and have confidently recommended this company to other expatriates in need of similar services.

Thus, it is without hesitation and based on personal experience that I can attest to Mertz International LLC's commitment to the highest standards of professionalism and integrity in this company's business endeavors.

I have had the privilege of being Michael Mertz’s client since 2016. As a US Citizen and a small business owner in Singapore who has been an expatriate living in Asia Pacific since 1996, it is critical to have a professional team you can depend on to stay on top of international tax matters and constant changes in tax laws for expatriates both in your home country and abroad. I travel a lot and have investments in multiple locations which makes my tax filing complex.

Michael and his team have been absolutely brilliant! They have saved me so much time, money and energy. Most importantly, I have peace of mind with them safely guiding me through what often feels like a minefield.

Michael is masterful. He and his team always go the extra mile, are highly responsive all throughout the entire year and are always available to answer questions. I really appreciate the fact that they stay on top of me with reminders to meet filing and tax payment deadlines that are not normally top of mind. I would highly recommend Mertz International to anyone!
