Mark Tirpak, EA

Managing Director

"I really enjoy the client service side of the business, exceeding clients' expectations in terms of responsiveness, and helping to simplify the complexities of expatriate taxation."

Mark serves as Managing Director for GTN. He has over 20 years of professional experience in advising multinational companies on global mobility related issues, including expatriate taxation, payroll, equity compensation planning, international assignment policy review, and program administration. He began his career with PwC's International Assignment Services practice in Tokyo, Japan; San Jose, CA; and Houston, TX. Being an expat himself has only enhanced his desire to assist and help simplify the process for the assignees who are overseas.

With his extensive experience in all areas of expatriate tax, Mark is best known for:
  • His responsiveness and attentiveness to each one of his clients' assignees;
  • His ability to simplify the complexities of expatriate taxation;
  • His eagerness to ensure expatriates (and their employers) fully benefit from the expatriate experience.

Mark earned his Bachelor of Science degree in business economics & public policy from Indiana University's Kelley School of Business and is an IRS Enrolled Agent. He also studied Economic Policy at American University in Washington, D.C. and Spanish at the Universidad de Sevilla in Spain.

In his free time, Mark enjoys spending time with his wife Mayumi and daughter Lily. He also enjoys hiking, camping, traveling, and reading.
