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.


Professionals dedicated to international taxation. Our specialized team is made up of experts in international taxation, not catch-all consultants with only superficial international experience.

In-house employees, not contractors. Our entire staff is made up of in-house employees, not contractors. This translates to higher commitment, greater consistency, and lower turnover.

Commitment to quality. We are dedicated to providing you with only the highest-quality service. You can rest assured that every member of our team will take the time to do the work right.


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.


Multilingual staff. Our staff members speak multiple languages, reducing the need for document translation and allowing us to communicate with you more quickly and effectively.


Security. Our secure technological infrastructure is designed to include redundant backups. This means never having to worry that your information will be lost in the case of a system failure.

Technology. We use the most advanced technology for our communications, with a client portal that allows for secure transmission of documents across the globe.


Proven Track Record. With close to 15 years of success under our belts, we have the track record to back up our claims of experience and expertise—so that relying on us makes more sense than ever.
