New York-based KPMG LLP has announced that Douglas O'Donnell, former IRS acting commissioner, has joined the firm as a senior managing director within its Washington national tax practice. The hire comes at a critical time as multinational taxpayers face an unprecedented increase in cross-border tax disputes and enhanced enforcement efforts from tax administrations worldwide.

O'Donnell brings nearly four decades of leadership from the IRS, where he held the agency's most senior roles, including acting commissioner, deputy commissioner and commissioner of the large business and international division. As acting commissioner and deputy commissioner, he oversaw approximately 100,000 employees while leading strategic planning and organizational transformation efforts across the agency during a period of significant modernization.

"Doug's unparalleled leadership and deep understanding of the tax landscape will be invaluable to our clients as they navigate an increasingly complex regulatory environment," said Rema Serafi, vice chair - tax, KPMG LLP. "Doug strengthens our ability to deliver the highest level of tax expertise and regulatory insight our clients need to manage these challenges effectively."

"Doug's extensive experience with foreign tax administrations, particularly through his participation in the OECD Forum on Tax Administration, makes him an ideal addition to our Washington national tax practice," adds Danielle Rolfes, PIC - Washington national tax, KPMG LLP. "As tax authorities around the world intensify enforcement, Doug's expertise in global tax issues and dispute resolution will provide our clients with even deeper insights and strategic guidance."

In his new role, O'Donnell will co-lead the tax controversy & dispute resolution (TCDR) group within Washington national tax, where he will help clients navigate complex tax issues with the IRS and foreign tax authorities. He will also assist clients with developing dispute prevention strategies to minimize tax controversy exposure.

"I'm excited to join the leading Washington national tax practice at KPMG and contribute to the firm's exceptional brand," said O'Donnell. "The commitment of KPMG to delivering unparalleled value to clients during this dynamic period in tax administration aligns perfectly with my passion for helping organizations navigate complex challenges."
