Worked seamlessly with our US accountant

We worked with Arnold and his staff at OrangeTax for several years during our residence in the Netherlands, as well as after our return to the United States. They are the perfect choice for expats living in NL, and they worked seamlessly with our US accountant. Professional, helpful and timely – we couldn’t have asked for more. Highly recommend!

Jed Rauscher

Fast turn around!

Quick and easy! Have been working with OrangeTax for the past 5 years and will continue to do so. Very helpful in answering questions, updates when needed and overall have an extremally fast turn around! Kelly and Arnold have both been great – would HIGHLY recommend!

Hanna Schiller

Efficient and helpful assistance

Orange Tax gave us very efficient and helpful assistance with our filing for our 2021 NL tax returns. It was so much easier than with our previous accountants and we will most certainly be back in the beginning of 2023 for help with our 2022 returns.

Katy Hull

No hidden charges

Great, Great service. Over the last 2 years, Kelly has been always incredibly helpful, responsive and very knowledgeable. Pricing is absolutely fair with no hidden charges or unexpected items (which was my main issue with another Tax Advisor i reviewed in the past). I would genuinely recommend Orange Tax to anyone. Arnold and Sharon also very helpful and always keen to support and provide feedback upon queries.

Simone Mallardi

Ease and professionalism

The level of ease and professionalism was outstanding when using Orange Tax. I left the Netherlands last year, and I was worried that I might have missed my chance for filing my returns since I was overseas. Kelly from Orange Tax was super reliant, professional and made it very easy for me to understand and file my return. Thank you!


Made everything happen!

Great service! I was really stressed about filling our first tax forms in NL as expats. After contacting 4 other companies with no answer, i called OrangeTax. A very friendly lady explained to me how it will work, then I sent an email with all our details and within a couple of days it was done. Arnold was very prompt, answered all my questions and made everything happen! So definitely I recommend them, such an easy process!

Andra Copocean

Pleasant service

I’ve had positive experience with Orange Tax for past two years. Kelly has been extremely helpful and prompt in response to my queries. Thank you for your pleasant service. Highly recommended for quick and efficient tax related services.

Vishnu Madhusoodhanan

Indescribable relief

Best money I ever spent! I had been worrying and stressing about how complicated my taxes were going to be for months as I was in a special situation as an expat. I never used an accountant before but I thought I would reach out to see if they could help. Within HALF A DAY my taxes were done, all my questions answered, and the relief I felt was indescribable. I didn’t even have to leave my house in Rotterdam! It was great to have experts in expat tax help out and be so willing to help. 100% recommend!

Ellie Connor

Above and beyond…

I’m hesitating to post a review here, because I don’t want everyone to know how good they are, because I want to keep them for myself 😀 But they have gone above and beyond the call of duty in helping me, so they deserve it – I’ve dealt with six different accountancy / tax advice companies in the UK and NL over the years, and OrangeTax has been the absolute best. Quick responses, good advice, reasonable pricing.

Laurence Taylor

5 star rating !!

I have moved my tax services to Orange since 2 years with full satisfaction. You get the job done in an efficient, fast and best price quality ratio. Even though your tax situation is complex they clear it smoothly. Recently had a peculiar situation where I seemed their help and tax analyst provided immediate advice. Had to go back since the recommendation from orange could not be implemented and then senior tax advisor stepped in to give me peace of mind on the case. I have experienced many expat tax services in different countries and I give them 5 star rating !!

Luca Govean

Fantastic experience

Fantastic experience as always. Thanks Orange tax for sorting out my 2021 return quickly and easily. I can definitely recommend them for all your tax needs

Michael Donian

Good service, very happy

Life of an expatriate is hard (even in NL where everybody speak English), and it is not the easiest especially when it comes to tax matters. Orange Tax was quick to answer: initial conversation next day, very helpful and friendly. I have had exceptionally bad experience with the majors accountants; here I sense we have a team that actually knows what they are talking about, understand the problems and actually take the time to work on the case. Good service, very happy, glad to recommend.

Danny Kay

Thorough explanations

I’ve been navigating some complex tax questions and Arnold and his team at OrangeTax have been extremely helpful throughout this process. They were responsive and quick to answer my questions and give thorough explanations of what I needed to do, as well as provide estimations of what I would owe depending on the immigration path I’d pursue. Would recommend!

Elena Pueraro

Outstanding service

I would recommend OrangeTax to anyone looking for clear, comprehensive and friendly tax advice. Arnold and his team think along with you to find creative solutions for your tax issues based on their expert knowledge and wealth of experience. The service provided to me was nothing short of outstanding. Thank you Arnold!

Anita Raghunath

Would highly recommend

I am an expat with a complex tax situation. Arnold from OrangeTax methodically went through the situation and provided clarity in a thorough, efficient and professional manner. He is impressively knowledgable, very responsive and super friendly. Many thanks Arnold and team. I look forward to working with you for many years to come. Would highly recommend to others if you’re looking for help with your taxes!

Jake Fairnie

Responsive service

I have been a client of Orange Tax for seven years. The professionalism and responsiveness is without equal. Arnold and his team are outstanding professionals and have provided exemplary and responsive service to me, an expat since day one. I highly recommend this outstanding organization and its team members.

Tim Mescon

Helped me to save some money

I had an amazing experience working with Kelly from OrangeTax team: she was super professional, responded within an hour and prepared the return accurately and quickly. I first tried preparing the return by myself, but then Kelly corrected some of my mistakes and helped me save some money. Thank you for giving me the piece of my mind about my taxes 🙂

Elena Katliarova

Quick to respond

Kelly Postema of OrangeTax was so helpful and quick to respond on all my inquiries. For an expat taking care of taxes in the Netherlands, it can at times be quite intimidating, and Kelly made this experience as smooth and easy as possible. Thanks again for everything !

Andrew Lane

Tireless commitment

Never receive such an assistance for highly important matters before! Thanks to Mrs. Sharon and Kelly for their brilliant work, patience, and their tireless commitment: without their mediation don’t know if I would have been able to solve issues, considering that the more famous and sponsorized ‘social and governamental authorities’ were totally unhelpful! Once again Thanks for your precious work!

Steiger Eiland

Extreme care

Orange Tax was recommended to us upon our arrival at The Netherlands. During the 6 years of our stay in the country, they assisted us with all kind of tax and administrative matters, exhibiting knowledge, expertise, diligence and extreme care. Thank you to all professionals of Orange Tax. You made our life much easier.

Pedro Carmo

Exceeds expectations

Orange taxes is very professional and replied really fast with regards to our tax return. They solved all our questions quite fast and very much in detail. Our mortgage advisor recommended them and included 2 years of free services for the mortgage preliminary tax refund. When we initially contacted them for the preliminary tax refund they took a lot of time to reply to our emails and some times didn’t solve our doubts satisfactorily. At the end we understood where the misunderstanding was and they helped us filling a quite accurate preliminary refund calculation. Demonstrated by the tax return calculation the following year. Overall we definitely recommend orange taxes. I have experience from other tax consultancy companies and orange taxes definitely exceeds expectations.

Erika Durán

Quick, clear and helpful

If someone deserves a medal for most helpful, kind and responsive tax expert, it would be Arnold. He is so quick to respond, which can put a worrying mind at ease. I was looking for clarity on my tax assessment, and he was able to explain within minutes what the letters from the Authorities meant, which was not clearly translated by Google (I guess it has its limits!) I would 100000% recommend his services and would not hesitate a second to hire him for my next filing. He is really amazing!

Adriana Briceno


I’ve been using Orange Tax for many years now, and I’m always happy about their responsiveness to my requests/needs and their accuracy. I can highly recommend them.

Grazia Maria Giordano

They understand my needs

I have been living in The Netherlands for a few years now. When I used Expat Mortgages, they put me in touch with Orange Tax and I have to say their service has been excellent from Day 1. They understand my needs and Hermin keeps me updated and looks after me even when I forget to send her documents! I have no problem in recommending Orange Tax t anybody looking for a Dutch based tax service.

Dom Smith

By far the best in terms of service

I’ve been working with OrangeTax since I purchased an apartment two years ago. I’ve worked with a number of accounting practices in the Amsterdam area over the years, and OrangeTax is by far the best in terms of service. Often with other accounting firms, I have to wait for weeks to get responses, even for the most straightforward questions, but not so with OrangeTax! I recommend them to all my friends and colleagues, particularly my expat friends. Recommended!


Exciting and easy

Dealing with tax is the most boring thing in the world, but OrangeTax makes this very exciting and easy. Great team with excellent professionalism. They are extremely responsive and solution-oriented.

Mutlu Gunenc

Resolved on Zoom

Very pleasant experience. I had some tax concers, being an expat in the Netherlands and Arnold was able to resolve all of them in a short call over zoom. I recommend!

Ivelin Slavov

Honest with their pricing and time

Look no further if you are an expat moving to the NL. Their team is competent, friendly and flexible. I had a tricky tax situation that i wanted to fix and do correctly and they guided me through the whole process. They answered all my questions and are SO honest with their pricing and time!!! Definitely worth the extra dollar. 100% reccomend.

Samuel Barreto Villanueva


My husband and I had some questions about the Dutch tax in general. OrangeTax replied to our email and set up a call promptly to discuss the questions we had and provided very useful advise. Arnold is very knowledgeable of the Dutch wealth tax which should be helpful to all expats living in the NL.

Akemi Micallef

Great result

Arnold is knowledgeable, very responsive, and pleasant to talk to. He helped us figure out Dutch tax details associated with our move over email and phone and we’re very happy with the result. Thanks!

Bjorn Hubert-Wallander

Five words…

I’ll describe Orange Service in 5 words: Fast, fast, knowledgeable, reliable and fast.

Recommended for expats!

Omar Ahmed García Pérez

Successful application

I applied for the 30% some years ago by myself and it was rejected. I asked Orange Tax Services to help me with my appeal. They were extremely thorough and my application was successful. Now, 4 years after this, I keep asking them questions about this and they are amazingly fast and helpful in their responses. I highly recommend them!

Konstantinos Bischiniotis - 30% ruling claimant

Fast, efficient, understanding

I first met Arnold about a year after moving to The Netherlands from abroad (around 2009). I’ve have used his services ever since. I needed someone who could handle my Dutch income tax preparation as an expat, and also with the 30% ruling, plus the added complexity of buying a home locally. In all counts Arnold and Orange Tax more than met my needs. What I appreciate most about them is that they were always fast and efficient in everything they did. They also understand that expats take time to integrate into the Dutch way of life, and so everyone was very gentle and understanding when we asked 1000s of sometimes basic questions. I don’t often write reviews but in this case I am quite happy to do this.

Thank you Arnold and all the team.

Joseph Ezerski

A remarkable company!

Coming from South Africa I was completely unprepared for how efficient Orange Tax is. I received a mail from them informing me that I can send in my particulars to them and within 5 minutes of me sending it in I received a mail informing me that my Tax has been completed and that I will be receiving an amount back. This is unheard off and by far the very best service I have yet received in the Netherlands. Truly a remarkable company!!!

Vanessa Riggs

Fast and precise

This is the second consecutive year that I use Orange Tax as my tax advisor. They are quite fast and precise.

The cost is very good and the quality and satisfactory is excellent. I suggest Orange Tax to anyone who needs experienced and fast tax advisor.

Ali Yousefi Sabzevar

Help with software

Bianca at Orange Tax has been incredibly helpful with our trouble getting our bank linked to our accounting software. She has been informative, available, friendly, and delightful. Well done, Bianca! Thank you!

Mary Clark

Highly recommended

I’m a former Dutch tax resident/skilled migrant (30% rule). The Dutch tax authorities recently challenged one of my Dutch tax returns, which had been initially approved. After consulting with my trusted advisers at Orange Tax, they took over, communicated with the tax authorities (teaching them how to apply their own laws) and settled the issue. I highly recommend OrangeTax to any expat seeking professional tax services.

T DePep - 30% ruling claimant

Refreshing openness

I wish that I could give Orange Tax Services 10 stars. People there have extensive expertise on tax requirements that the Netherlands requires of its expat residents. And the company is willing to share this expertise with its clients. (At the bottom of their every e-mail is the statement, “Please do not hesitate to contact us, should you require any further information or assistance.” And they mean it!) Applying his company’s policy of openness with its clients, Arnold Waal took the time not only to do my Dutch taxes (which every Dutch tax service is happy to do), but also to respond to my questions about how the Dutch tax system works. This openness is something that I have not been able to find with any other tax service here in the Netherlands.

About us: My wife and I are retired and dual citizens of both the United States and the Netherlands. One month ago we discovered that we needed to pay Dutch income taxes retroactively back to 2015 (!), despite the fact that all of our income has been from retirement annuities in the US. Suddenly, we needed to learn about how taxes are levied in the Netherlands in light of an impossible-to-fathom NL-US treaty to prevent double-taxation. In a growing panic, we contacted Dutch tax experts for weeks in hopes that somebody could explain the rules. But no. With the exception of Orange Tax Services, the response was always the same: You pay us and provide us numbers, then we do your taxes for you.

Let me illustrate what I mean by openness. Here is an excerpt from Arnold Waal’s response to a series of questions I asked in my initial e-mail contact with Orange Tax Services:

–If you moved to the Netherlands in 2015, we need to file a Dutch migration income tax return.
–Your US retirement income should be reported in this tax return, since the Dutch-US tax treaty states that only the Netherlands can tax this income. The exception to this rule is if you were working as a US employee, for instance in the military, police, justice, etc. If that is not the case, the income is taxed in the Netherlands.
–The amounts you withdraw from your 401K are taxed in the Netherlands.
–The amounts you withdraw from your IRA are taxed in the Netherlands.
–Your Roth IRA’s value is taxed (as wealth) in the Netherlands, not what you withdraw from it.
–Your savings (not including amounts in your 401K or IRA) are taxed in the Netherlands as wealth.
–The value of your house in the US is reported in your Dutch tax return, but is not taxed in the Netherlands. You get a credit for its value, which eliminates any tax on it.
–My understanding of US tax returns is that you should file the Dutch tax return before filing your US tax return. So if you would like us to file your Dutch returns, have us file them before you submit your US tax returns.

How is that for clarity? And beyond this, they sent detailed copies of our tax returns for our review prior to filing them. This is what I call working “with” your clients, not just working “for” them. If you do not understand the rules, you cannot make a financial plan; and without a plan, you are paralyzed. Thus Orange Tax Services not only did our Dutch taxes but–more importantly–helped us understand, so that we could plan and overcome our paralysis. That’s why 5 (or even 10) stars are not enough to express how grateful we are to this company.

Carl Roberts

Helpful and prompt

Orange Tax Services are absolute superstars. They have taken care of all my freelancer taxes now for 6 years and I couldn’t be happier. I have received very helpful and prompt responses to my tax questions, all the VAT and income tax returns have been brilliant and precise. I definitely recommend Orange Tax Services to everyone, especially expats.

Sam Heikkinen

Clear, direct

Asked them a random question over email – got a response, and a few follow ups within a few hours. Clear, direct, immediate, wonderful. I wish taxes were always that easy 🙂

Paweł Królikowski

Total superstars!

For many years Orange Tax Services have gone above and beyond to help keep my taxes in order. They are hands down the most skilled and personable tax advisors I’ve had the pleasure to work with in the Netherlands. A nightmarish, Kafkaesque situation occured to me several years ago where the tax office had somehow duplicated me in their systems but took no responsibility to fix it. It seemed impossible to rectify directly with the tax office, until Arnold at Orange Tax Services came to my rescue and effortlessly fixed the whole mess. Total superstars! I am also a business owner and wouldn’t trust anyone but Orange to handle my tax affairs. In short, the best in town!

Philip Howe


I have been a client of Orange Tax Service for about a decade now and have had nothing but good experience with every tax-related task or query I had. Their efficiency never ceases to amaze me!

Igor Francé

Professional and trustworthy

We have been working with Orange Tax for several years. As a U.S. tax advisor, it is important that I know my clients have an experienced and trustworthy Dutch tax advisor to consult with on their complex expat tax issues. I recommend my clients to Orange Tax because I know they will receive an excellent and professional service.

Christie DuChateau - Tax Advisor

The easiest, nicest, fastest, funniest tax guy in Amsterdam

Arnold has been my go-to tax guy for over 10 years. From my very first fiscal cry for help, he has helped me with all my tax returns and advice. My Dutch husband even switched to him, as he’s really just the best. He’s fast, efficient and incredibly funny. Highly recommended.

Emma Vans-Colina

Orange Taxes makes dificult things easy for you

I first was introduced to Arnold and Orange Taxes in 2009, when I was in need of a capable tax advisor who could help this expat file his Dutch taxes. I have used his services ever since.
Everything can be done in English (or Dutch of course!). Arnold is careful and patient and always willing to explain how things work and how to best proceed. In my case, I also had the 30% ruling in addition to purchasing a home in Amsterdam for the long term.
One of the things I appreciate most about Arnold and Orange Tax is that they are fast and efficient. Filing taxes is never fun, but honestly, Arnold and his team take on all the work and make sure you are filing correctly. They make it easy. Even payment is easy with modern online banking options.
Overall as pleasant an experience as you could wish for on such a topic as taxes. Taxes are “exciting” for me because Orange got them done fast and I don’t have to worry about it anymore.
I highly recommend his services to anyone who asks and I almost never give online reviews. Orange Tax has won my loyalty through good service, so I am happy to write this.

Professional excellence

I am a Norwegian citizen who lives in the Netherlands and was the subject of tax treaty issues between the two countries. I was lucky to find Arnold C.J Waal at OrangeTax. He undertook and resolved my taxation issues with great care, diligence and professional excellence. If you’re an expatriate and have Dutch taxation issues, rest assured that you would receive outstanding advice and assistance from Arnold C.J. Waal and OrangeTax.

Tanya Kollenberg
Norwegian expat

Very professional

We are a Swiss company having a few employees working in Holland. Since 2009 OrangeTax has been supporting us on a very professional basis. OrangeTax helped us to set everything up in Holland (including Bank accounts) and acts on our behalf with the Belastingdienst. They provide pay slips for the employees, declare their salaries to the tax office and do all reports needed. OrangeTax keep us informed of any relevant Dutch news that could concern us. They always reply promptly to any question we have and we are very happy with the quality of the service they provide.

Manuela Oberegger
Lewry Technical Services Europe AG

Good with people

I would highly recommend OrangeTax for any business owner looking for expert accounting, efficiency and excellence. Arnold and his team makes a refreshing change from the dull, grey accountant stereotype because they’re not just good with numbers, they’re good with people too.

Juraj Fabuš

Experienced tax advisors

We offer companies to either locate here at our EBC Amsterdam office on the Keizersgracht, or use our virtual office solutions with the use of meeting rooms. A business centre like ours offers offices for flexible periods of time, whereas the common lease of an office in the Netherlands is a five-year period. If your business grows, you basically grow into a lease problem. A problem you do not have with our flexible solutions. We do this with style and that sets us apart from our competitors. Arnold Waal I have known since the mid 90’s when he was a junior tax advisor working opposite the EBC Amsterdam. Since 2005 Arnold’s company, OrangeTax, is a much-appreciated client of EBC Amsterdam. We have the opinion Arnold and his team are experienced tax advisors, hands-on and eager to assist you with tax matters. Many people think tax is boring, but Arnold advocates that tax is exciting!

Maaike Verdonkschot

Proactivity to manage my tax affairs

As President of Starbucks Coffee Company EMEA and Chairman and CEO of V&D in the Netherlands between 2001 and 2013 I was supported in all my personal tax affairs by Arnold CJ Waal and his team at OrangeTax. The advice, efficiency and proactivity to manage my tax affairs was always of the highest professional standard and I would highly recommend to any ex-patriot visiting the Netherlands for business the services of Arnold and his OrangeTax team.

Mark McKeon

Willingness to take on a unique case

I moved to NL for a tax-free position with an international organization, and after 5 years transferred to a local Dutch employer. OrangeTax successfully requested the 30% rule for me, as I was originally brought to NL for specialized work and would have qualified for the 30% ruling, but it was not necessary as my salary was not subject to tax. I was able to receive the 30% for the remaining eligible years, which has been a great benefit to both me and my employer. Arnold’s expertise, availability, and willingness to take on a unique case was above and beyond what I expected and well beyond my experience with other tax services. For any future tax needs I will go directly to OrangeTax and cannot recommend them highly enough.

Sarah Brown
30% ruling claimant

International calibre service

As an expat, entrepreneur and consultant in the Financial Services industry, I have to be able to rely on an efficient and accessible book keeping and tax service. OrangeTax has successfuly provided me with that security for 5 years, consisting of solid advice and same day responses to my ad hoc queries. Often in the Netherlands, an international calibre service is hard to find, but with OrangeTax, there is no need to look further.

Expert advice

I am extremely satisfied with the level of service I received from OrangeTax. Not only are they very diligent with their work, but they also possess excellent customer service and are always available for any query you may have. As a foreigner in the Netherlands, it felt great to receive such expert advice especially with regards to the 30% ruling, which, thanks to OrangeTax, I have been granted. I am currently in the process of buying a house in the Netherlands and there is no doubt that OrangeTax will be my go-to tax advisers for the tax implications involved with a home purchase in the Netherlands. Great value for money! I highly recommend them!

Hala Abu-Jaber

Repatriation made easy

I am a Dutch national working for international development organizations, always abroad. Three years ago I moved back to The Netherlands. An expat colleague suggested that I get in touch with Arnold Waal to discuss tax issues related to repatriation. The contact with OrangeTax was very efficient and friendly. I am very satisfied with the excellent professional services of Arnold and his team. They work fast and with good results.
