About Us

International taxation. Admittedly, not the sexiest of topics for most people. But we at Esquire Group aren’t most people.


Not only is the team at Esquire Group dedicated to international taxation, with specialized knowledge drawn from years of experience, but we also know first-hand what running a successful global company entails. With offices in multiple countries, we recognize the actual challenges of conducting international business, from cross-border tax issues down to managing multiple languages, currencies, and time zones. And, since many of us live as expats or as members of multinational families ourselves, we understand the realities of those challenges as well.


In other words, we get it.


For almost 15 years, Esquire Group has been helping clients navigate the complicated world of international tax matters. Because we are a boutique firm, we provide our clients with the kind of highly personalized service you won’t get from sprawling corporations. You’ll get to deal directly with our experts and dedicated in-house employees—who have been carefully selected by founder and CEO Jimmy Sexton, LL.M.—instead of being relegated to seasonal contractors.

As an international tax advisory firm with a global presence, we specialize in strategic advice, compliance, and tax preparation for both individual and corporate clients, including:

  • Americans living abroad (expats)
  • U.S. Residents with foreign income or assets
  • Nonresidents with U.S. source income
  • High-net worth individuals
  • Family offices
  • SMEs engaged in international business
  • Foreign financial institutions

Business today is no longer constrained by borders, moving faster than ever before. By continuously embracing innovative technologies, we at Esquire Group can match the pace of your business, maximize productivity, and communicate securely.

Whether that means using our cutting-edge client portal or jumping on a plane to meet you in person—wherever in the world that may be—is entirely up to you.

Why Esquire Group?

When you work with Esquire Group, you will be working with experts. Our team has the specialized experience necessary to provide you with secure, dedicated, and truly international service.

Offices in multiple time zones. With offices across 3 continents, we have team members working in multiple time zones so that we can be available whenever you need us.

Meet the Team

  • Jimmy Sexton, LL.M.

    Founder & CEO

    Visionary & Hardworking

    Though it may sound odd coming from the founder and CEO of the company, Jimmy Sexton is quite proud of the fact that he’s never had a job. A job, that is, in the sense of working for somebody else from 9 to 5 each day. Instead, he graduated from college, found himself unable to find a job, and decided to start his own business.

    That was in 2005. Since then, Jimmy has grown Esquire Group into a successful international firm with offices in four countries—Austria, Germany, the UAE, and the U.S. From his base in Dubai, he regularly travels throughout the Middle East, Europe, and the Americas meeting with clients, speaking, and overseeing Esquire Group’s global operations. In his role as advisor, his primary focus is on advanced tax planning strategies for high-net worth and corporate clients, specializing in corporate structuring, expatriation, wealth structuring, and U.S. tax compliance.

    A self-confessed perfectionist, Jimmy is always challenging himself to improve everything—himself, his business, his clients’ experience with the company. He refuses to cut corners and adheres to his values regardless of the consequences. His dedication to both the vision and daily operations of Esquire Group infuses not only his decision-making, but also his treatment of his employees and his passionate commitment to his clients.

    Perhaps just as important is Jimmy’s non-traditional background as an international entrepreneur who himself lives overseas. Because of the breadth of his first-hand experience, Jimmy is able to offer clients a unique, more holistic perspective that goes beyond any individual tax issue. He combines in-depth expertise in international taxation with an awareness of more practical matters, such as strategy implementation and the nitty-gritty of banking, language, and time zone issues.

    Jimmy holds a Bachelor of Science degree in Business Administration with an emphasis in Finance, a Juris Doctor (J.D.) degree, and a Master of Laws (LL.M.) postgraduate degree in International Taxation.

    As a longtime expat, an international tax advisor, and an instrument rated private pilot, Jimmy spends an inordinate amount of time on airplanes. When he is on the ground, he is usually working, snowboarding, or at the gym.

  • Mike Abel, Esq., LL.M.

    In-house Counsel

    Analytical & Trustworthy

    Mike Abel is a longstanding and trusted member of the Esquire Group team as well as an accomplished lawyer with his own firm. Not only have his decades of experience granted him an enviable level of expertise in his field, but they have also instilled in him a deep-seated understanding of the value of honesty and integrity.

    Recognized as a legal expert in the sectors of asset protection, corporate structuring, real estate, and financing, Mike possesses an ability to analyze complex situations and discuss them in a way that clients can easily understand. His knowledge and attention to detail have proven particularly invaluable to global clients looking to make U.S. real property investments.

    Personable and level-headed, Mike manages to be persuasive without ever resorting to metaphorical chest-thumping or empty shows of ego. He steers clear of grandstanding, relying instead on the strength of his work and the validity of his positions to communicate effectively with his clients and find solutions to their problems. His depth of experience and out-of-the-box thinking make him perfectly suited for his vital role as Of Counsel.

    In addition to founding the Abel Law Group, PLLC, Mike also founded and built a real estate title company from the ground up, currently employing over 100 people across 20 states. His real-world business savvy adds a unique dimension to the legal analysis and international taxation advice that he is able to offer to his clients.

    Mike holds a Bachelor of Arts degree in Business Management, a Juris Doctorate (J.D.) degree, and a Master of Laws (LL.M.) degree in International Taxation, which he was awarded Summa Cum Laude.

    When he is not working or researching nuanced issues out of sheer curiosity, Mike likes to read, eat great food, and spend time with his family.
