An absolute pleasure to deal with Jovan and Olivier, they take all the stress out of tax preparation!
All the people at 1040 are very pleasant to deal with, they are efficient and all questions are answered promptly. I have been using them for three years now and highly recommend their services.
My experience with 1040 Abroad over a number of years has been more than satisfactory. My questions have always been answered and my forgotten details have been dealt with, with a smile. (A special call out to Jovan this year for his patience and sense of humor.) I recommend Olivier Wagner and his team without reservation.
I have been using 1040 Abroad for several years to file my US Taxes. They continue to provide a timely and professional service and are always a pleasure to deal with. I continue to recommend them.
They helped me get through the “Relief Procedures For Certain Former Citizens” with a minimum of personal information. Their questionnaire was straightforward and required very little time to fill in. Questions were answered in very short time and all documents were processed on a secure server.
Great to work with. Timely, knowledgeable, reasonably priced and dependable. Look forward to working together in the future 🙂
Right from the start I have had terrific support, clear explanations of what I need to do and why. I recommend them highly.
I cannot appreciate enough Olivier Wagner, Jovan Stojanovic and 1040 Abroad. They have been thorough, professional, kind, and helpful with my US tax filing. I recommend them wholeheartedly! They came up with solutions to questions I had, and I feel that my US tax filing is in the very best hands. Highly recommended! 10 stars!
The team at 1040 Abroad was wonderful and supportive. They knew exactly what I needed to do, prepared documentation meticulously and timely, and answered all of my questions. They were transparent and true to their estimated costs.
Crystal clear communications, prompt service, and the 1040 Abroad team was fast to respond to all the queries we had.
I've been working with Oliver and his team at 1040 Abroad for several years now, and I can't recommend them enough. They make the entire tax return process as smooth and stress-free as possible. It's always a pleasure working with them — professional, efficient, and incredibly helpful every step of the way. If you're looking for reliable support with your taxes, 1040 Abroad is a great choice.
Quick, accurate and reasonably priced.
"100% first rate service from the team. Easy to work with and very responsive! Highly recommend!"
1040 (Olivier and Jovan) were great. Reasonably priced and super knowledgeable, I will be using them for the long term I think!
I can't recommend Olivier and his team more highly. Extremely trustworthy and professional and managed to sort out all of my US tax issues. Will definitely be using 1040 Abroad to do all my US tax in the future.
1040 Abroad is for my personal experience the most efficient IRS adviser I have ever used. I live abroad and the office can manage eveything to fulfill US citizens IRS forms. From establishment to filing it is all quite smooth and effective. Finally rather unexpensive at the end.
Clear communication and always ready to answer questions. Excellent knowledge and very easy to deal with.
EDITED TO ADD Dec 23 2025: Olivier of 1040 Abroad reached out and paid the penalties on the late fees incurred due to my case falling through the cracks in their process. He mentioned that regardless of my review, he wanted to make things right. As a business owner, I fully understand that mistakes happen. I wanted to take a moment and acknowledge my appreciation for businesses like these with integrity. ----------------------------------------------------------- I had used 1040 Abroad in 2024 as a US citizen living abroad full time. Things went well so I decided to use them again for 2025. Biggest mistake I ever made. Note that I have NEVER been late in filing my taxes. This all happened despite an onboarding call PRIOR to doing my taxes. I had explained before hand that my taxes are complicated for 2025 due to living in two countries, sale of properties and running two separate businesses. Let me save you the pain. 1. I submitted my taxes at least a month in advance like I normally do. 1040 gave me literally 2 days before the deadline to confirm and file my taxes even though I had asked for it the week before. 2. There were zero questions asked despite the sale and purchase of multiple properties and including the sale of my primary home which would allow for a 250k deduction. This was not included in my taxes. 3. The taxes I owed were astronomical due to #2 above. 4. They asked me, the client a basic non-negotiable tax filing question on which tax option I wanted to file (with K1 or without K1?) - When I asked for a second opinion, my usually polite and calm US based business accountant wrote back to me: "That’s the dumbest damn question ever. You HAVE TO FILE with the K1." 5. My taxes were filed late due to this back and forth with zero guidance on what to do. 6. I now owe thousands in late fees. I can't even begin to tell you how incompetent these people are. And they only have ONE job to do: Taxes for citizens living abroad. You truly can't make this stuff up.
We’re disappointed to see this review, as it contains multiple inaccuracies and misrepresents the facts of this client’s case. The client first contacted us before the April 15 IRS payment deadline. However, despite several follow-ups, she failed to provide the necessary information in a timely or complete manner, repeatedly stating that she “had a business to run.” Without the required details, it was not possible to finalize her return before the payment due date. For clarity, U.S. tax payments are always due by April 15, regardless of when the return is filed. The IRS automatically applies penalties and interest when taxes are paid after that date. This timing is determined by law, not by the tax preparer. At the client’s own request, we prepared two versions of the return: one including the K-1 income and one excluding it. To be absolutely clear, K-1 income is required by law to be reported. We prepared both versions solely because the client explicitly asked us to do so during our initial call. We would never omit any income or modify a return in a way that violates IRS rules. We have complete written records, email correspondence, and call notes verifying all of the above. These can be shared in redacted form with anyone who wishes to confirm the facts. Our firm stands by the accuracy and professionalism of our work. We do not take lightly when a client misrepresents events publicly. This review reflects a misunderstanding of IRS payment deadlines, a misstatement of the facts regarding the K-1, and the client’s own delays.
I would give it 10 Stars if I could! ✶✶✶✶✶✶✶✶✶✶ 1040 Tax Service is more efficient than tax services that cost twice as much. It is very professional and secure with a Private Portal. I've used it for several years now and always been pleased. I wish I could have found it years ago. Thank you.
Very helpful, patient and understanding, made it clear what I needed to do, explained everything well, and responded very quickly.
