I have known Alicea for almost 15 years now and she has gone from an employee, to a principal to now the sole owner of a international tax accounting firm. Alicea takes risks in our profession but her decisions are well thought out. She started her international tax firm right before the pandemic and it has grown substantially since then. At her NYC office she teaches her staff the fundamentals of international tax. Her clients are throughout the world including Europe, Mexico and South America. She has made presentations not only in the US, but in South America and Europe speaking either in English, Spanish, Portuguese or French. I am honored to call her my friend, colleague and mentor.

As an expat living abroad for over a decade, I’ve worked with various accounting firms — but none has matched the efficiency, expertise, cost-effectiveness, and personalised service that Global Taxes consistently delivers. Their approach is genuinely multinational and globally minded.
Alicea Castellanos, the director, is a highly focused and exceptional professional — truly a pleasure to work with — as are all the members of her team.

I met Alicea in 2012 and she has been a friend and a colleague since then. I am accountant but I do not do a lot of work in international tax but just last week I had a question on a sale of a controlled foreign corporation and Alicea helped me on how to record the transaction. Since Alicea started Global Taxes four years ago the Company has grown tremendously. Her ability to communicate in English, Spanish, Portuguese and French allow her to assist clients all over the world. Her articles on International tax appear regularly in Tax Stringer a publication of the CPA Journal. Alicea has overcome a lot her of obstacles in her career but I admire her ability to overcome these obstacles and achieve great success. I am proud to call her my friend.

I have never met Alicea or the great team at Global Taxes in person. Yet I know them all very well via emails and phone calls. This group of individuals has given me complete comfort. Something not easily achieved in the Global tax space. It has now been many years since I was lucky enough to work with Alicea and her team. I would never consider anyone else. I can not praise this group of people enough. It all starts with Alicea, her work ethic, knowledge, and kindness.

Private Client review:
I have been working with Alicea for some time now. She and her team have been one of the most refreshing and comforting experiences I have had in the field. In fact, they were recommended to me after going through some other unimpressive experiences.
Her and her team have a professionalism and knowledge base that shines through from the first meeting. That coupled with her ability to explain to someone like myself the basics of any particular situation is what puts her above and beyond the rest in my opinion.
I am sure there are many knowledgeable professionals in the space. But I consider myself lucky to have the pleasure of working with her and the team. Many have knowledge and professionalism, only a select few have the ability and choose to understand their clients thereby conveying important elements with clarity, tact, and compassion. Suffice it to say I would and have recommended her to anyone.
