Bart Massey

Family Office Tax Accountant

Bart Massey serves as the Family Office Tax Accountant for the Horizon Family Office Team. His career of more than three decades has been focused almost exclusively on communicating to the public, government leaders, and private clients on a range of tax administration, compliance, and policy matters.

While in public service, Bart served as a liaison between the Commissioner of the Internal Revenue Service and Congress; and prior to that, a tax policy advisor to a U.S. Senator serving as a leader in the development of the 2017 tax reform act. 

In the private sector, Bart worked as a specialist in the National Tax office of an international public accounting firm, advising the firm’s ultra-wealth clients on matters of federal tax policy. In this role, Bart helped clients understand the risks and trends present in the federal tax environment. 

Bart’s ability to clearly communicate with clients about complicated tax issues stems from his earliest days as an editor and journalist with one of the nation’s flagship journals on U.S. tax policy.

Outside of tax, Bart enjoys living a full life with family and friends and pursuing his love of the outdoors.
