I am an attorney and entrepreneur dedicated to the pursuit of personal freedom. I am a member of the Quebec and Ontario Bars, the founder of Expat Lawyer Inc., a Canadian law firm, and the lead tax advisor at One Percent Tax LLC, a U.S.-based international consulting agency. I speak English, French, and Spanish. I live in Costa Rica, having made the move myself, and I know precisely what it requires.
We help successful U.S. and Canadian entrepreneurs and investors legally reduce their taxes, protect their assets, and obtain second residences and citizenships. For some, that means relocating to a country that taxes them less, together with their eligible businesses. For others, it means restructuring what they already have, without moving at all. Our multidisciplinary team of lawyers, accountants, and bankers around the world delivers a complete, turnkey service, so you can invest your energy elsewhere.
The outcome depends on your situation. For some clients who meet certain requirements, the overall tax rate can be lowered to as little as one percent. For others, the proper strategies can still reduce tax liabilities by millions of dollars annually. As a courtesy reserved for the Tax Advisor Network, I offer clients who find me here a complimentary 30-minute consultation, time I would otherwise bill at my hourly rate ($500/hour), to determine what is possible in your situation.

Reviews for Marc
Sylvain Marsan
Marsan Transmission & Differential
After more than 30 years running my transmission shop in Quebec, my wife and I decided to move to Costa Rica. Marc built us a complete, step-by-step plan: the tax side of leaving Canada, our Costa Rican residency permits and every document to prepare before departure, the sale of the business, banking and investments, insurance, health care, estate planning, even buying a home and a car and settling into daily life once we arrive. He has made the move himself, and it shows: everything was explained in plain language and every question got a clear, direct answer. It gave us the confidence to go ahead. If you are an entrepreneur thinking about relocating, talk to Marc before you do anything else.

Working with Marc at One Percent Tax gave us a much clearer and more strategic approach to managing our business specializing in Persian and Oriental goods. Since our business involves sourcing and selling valuable works of art across international borders, our tax and business considerations go well beyond those of a typical domestic company. Marc immediately understood the complexities involved and helped us assess our operations from an international perspective. What impressed us most was Marc’s ability to take complex tax and international business issues and translate them into clear, practical strategies that were directly relevant to our company given the realities of doing business during periods of geopolitical instability, conflict, changing trade conditions, and commercial relationships across multiple jurisdictions. For entrepreneurs involved in international commerce who want to operate more efficiently, better understand their tax position, and make stronger strategic decisions without cutting corners, we highly recommend Marc for the exceptional quality and depth of his guidance.

DJ Alcky
As a professional DJ, performer, and influencer, I need support that reflects the realities of working internationally. Marc helped me secure international bookings and navigate their legal, commercial, and tax complexities. He went beyond explaining my obligations, helping move opportunities forward that would have been extremely difficult to pursue on my own. He helped me assess engagements, identify risks before committing, and understand their implications for my broader business. That included clarifying contractual responsibilities and payment terms so bookings could move forward with fewer uncertainties. He also helped me understand the tax implications of my international work. We looked beyond booking fees to consider how tax obligations could affect what I would ultimately retain. His guidance addressed both my performance work and my role as an influencer, including how promotional commitments fit alongside performance agreements. That broader perspective was valuable: he understood that an international engagement is more than an isolated contract. When questions involved event organizers or other advisers, he helped coordinate outstanding issues and keep the process moving. What stood out was his combination of cross-border legal knowledge, tax insight, business judgment, and practical follow-through. In my experience, that combination is rare. His follow-up support also made a difference when questions arose outside scheduled meetings. I came away with international engagements and a stronger approach to evaluating future opportunities. I would highly recommend Marc to performers, influencers, entrepreneurs, and other professionals who need someone who not only understands international business, but helps them achieve concrete results.

AdvantEdge Business Solutions
I came to Marc at One Percent Tax with operating businesses, real estate interests, and plans for a software venture with an international partner. I needed to understand how our different tax circumstances, existing entities, and future plans could fit together. I initially approached him about an offshore holding company. Drawing on his international experience and extensive network of professionals across jurisdictions, Marc recommended what was truly the best for me, whether domestic or foreign and I felt confident that his recommendations served my interests because he has no pressure toward a particular jurisdiction or structure. That combination of expertise, professional reach, and independent judgment would have been difficult for me to find on my own or through a professional whose practice, interest and expertise navigating complexities is limited to a single jurisdiction. Equally valuable was the care and follow-through he brought to the process. He considered the additional information I sent between calls and incorporated it into a focused, tailored follow-up. That attention gave me confidence that I could trust him to take the details seriously and consider their implications for my broader business. His guidance gave me clearer priorities, practical next steps, and a better understanding of potential costs and specialist support. It provided a stronger foundation for planning improvements to my existing businesses and developing the new venture. I would highly recommend Marc to entrepreneurs navigating complex business structures or international partnerships. His combination of expertise, sound judgment, and dependable follow-through made him a trusted resource for decisions that mattered to me.

La Cime
At La Cime, we manage multiple vacation rental properties and welcome international guests through Airbnb and our own website. Reservations, property preparation, changing requests, and team coordination all have to work together. Reliability is something we have to build into every stay. Marc at One Percent Tax helped us approach that challenge through both better management and prevention through organized information, clearer processes and better communication. That strategic discussion became tangible as he identified inconsistencies between our French and English booking information and suggested clearer conditions, privacy explanations, and service descriptions. For a business serving an international clientele, those details matter: expectations formed online can become misunderstandings, complaints, or disputes later. I appreciated how Marc connected the guest experience with the commercial risks and operational decisions behind it. His suggestions came with explanations of why they mattered and what to address first. I highly recommend Marc to vacation rental owners and hospitality entrepreneurs serving an international clientele who want to strengthen their operations, anticipate problems, and use modern technology thoughtfully to deliver a more dependable guest experience.

As a personal trainer working with clients internationally, clear communication and trust are essential to my business. Marc at One Percent Tax brought a valuable combination of practical business judgment to his review of how I present my services and communicate with prospective clients. He reviewed my website, client questionnaire, service descriptions, and international client contracts, identifying ways to explain my services more precisely, clarify why I collect certain information, and make privacy information easier to access. Marc demonstrated a unique ability to connect these details to the broader client relationship, which made him stand out as an excellent advisor considering the clear expectations people who engage with my business from different countries have. His guidance gave me a stronger foundation for communicating with my international clientele, and I would highly recommend Marc to personal trainers and online entrepreneurs serving clients across borders who value informed, complete and reliable assistance.

Animal Based Nutrition Research Foundation
As Executive Director of ABNRF, the Animal Based Nutrition Research Foundation, I balance our mission with the practical demands of running a nonprofit organization and arranging international events. Marc at One Percent Tax has helped us work through decisions involving our organizational structure, commercial responsibilities, and day-to-day operations by evaluating structural options, reviewing public-facing policies, and helping prepare documentation. What I value most is that Marc helps us understand what each option would actually involve: the time it would take, the work it would create, and the most efficient way to achieve our goals. This matters immensely when running a nonprofit, as unnecessary administration takes time and energy away from the mission. I also appreciate his dedication to answering follow-up questions and thinking through those practical details thoroughly with me. I know I can rely on him, and I would highly recommend Marc to nonprofit leaders looking for thoughtful business support, particularly when their activities extend across borders.
