Nonprofits and Tax-Exempt Organizations


Of Counsel


Preston Quesenberry advises clients throughout the nonprofit sector on a wide variety of legal and strategic issues, including qualification for tax-exempt status, unrelated business income tax (UBIT), charitable contributions, domestic and international grant-making, joint ventures, lobbying and political activities and executive compensation. He has a particular depth of experience advising charitable hospitals and other tax-exempt organizations on regulatory issues related to the Patient Protection and Affordable Care Act.

A former senior attorney in the Tax Exempt and Government Entities Division of the IRS Office of Chief Counsel, Mr. Quesenberry drafted many of the Treasury regulations and other published guidance that play a critical role in his clients’ business structures and operations. For example, during his tenure at the IRS, he was extensively involved in several guidance projects relating to the Affordable Care Act and regulations regarding supporting organizations and program-related investments. He also supported the Department of Justice and field attorneys with litigation and supervised attorneys in issuing private letter rulings and determination letters on exempt organization issues, including matters related to UBIT, private foundation excise taxes, political activities, and qualification for tax-exemption under a wide-variety of Code sections. In addition, he served as a senior attorney-advisor to the IRS Deputy Chief Counsel (Technical), in which role he reviewed all tax guidance approved by the IRS Office of Chief Counsel.

Loeb & Loeb LLP has a ‘depth of experience and knowledge, which, combined with the high level of client service, makes it very competitive in this area’. Tax specialists Diara Holmes and Marcus Owens joined the firm’s Washington DC office in 2015 from Caplin & Drysdale, Chartered and are commended for their ‘responsiveness and “can-do” attitude’. The firm makes use of its trusts and estates, charitable giving and tax practices to provide a full service to its not-for-profit clients and has been assisting clients in a range of matters, from defending tax-exemption status against the Internal Revenue Service (IRS), to assisting with charitable giving, program-related investments (PRIs) and setting up for-profit subsidiaries. Recent highlights include advising Audrey Irmas on the gift and sale of a piece of art. New York-based lawyers Jason Lilien and Eliot Green are also recommended, as is Leah Bishop in Los Angeles. The firm strengthened its team via the acquisition of Preston Quesenberry to its Washington DC team as of counsel; Quesenberry brings a wealth of knowledge from his previous role as a senior attorney in the Tax Exempt and Government Entities division at the IRS Office of Chief Counsel.
