Dellinger, Gallegos honored by AICPA Tax Division

Arthur J. “Kip” Dellinger Jr., CPA, and Mark Gallegos, CPA, MST, have been named recipients of prestigious annual AICPA Tax Division honors.

Dellinger received the Arthur J. Dixon Memorial Award, and Gallegos received the Jonathan Horn Distinguished Service Award during the 2026 AICPA National Tax Conference.

The Arthur J. Dixon Award is the accounting profession’s highest honor in the area of tax. According to a news release, it recognizes distinguished service and a career of contributions and volunteerism. The Jonathan Horn Distinguished Service Award is bestowed for outstanding current contribution to the AICPA Tax Division for the past committee year.

Dellinger has served the AICPA as a volunteer for nearly 35 years, dedicating time as either a chair or member of 10 committees and task forces within the Tax Division. Most recently, he served as chair of the AICPA’s Circular 230 Revision Task Force and its Professional Ethics Executive Committee.

“Kip’s more than 30 years of volunteer service is a testament to his dedication to both the advancement of the accounting profession and the AICPA,” said Cheri Hutchinson Freeh, CPA, CGMA, chair of the AICPA Tax Executive Committee. “Through his volunteer committee participation, webcast presentations, and the many articles he has published over his long career, Kip has shown his truly extensive understanding of tax ethics, quality management, professional standards, and risk-related issues. All of these professional attributes are only exceeded by his generosity to share this knowledge with fellow practitioners in a manner that is easily understood by both entry-level staff and seasoned professionals.”

Gallegos has been an active member of both the AICPA’s Tax Practice Management Committee and Annual State Tax Compliance Task Force the past committee year. A tax partner on Porte Brown’s tax services team in Chicago, he served as a speaker at the 2025 and 2026 tax conferences.

“Mark consistently demonstrates exceptional dedication and selflessness in his volunteer efforts,” Freeh said. “He has been one of our most valuable speakers, willingly sharing his expertise and advancing the mission of the AICPA Tax Division via appearances at multiple AICPA conferences, on our Town Hall broadcasts, and podcasts. Mark embodies the spirit of volunteer leadership, going above and beyond in support of the accounting profession.”
