Shane Hamilton has represented tax-exempt, nonprofit organizations in connection with their federal tax and nonprofit governance matters for over two decades, including family- and company-sponsored private foundations, publicly supported charities, supporting organizations, social welfare organizations, and trade associations. He regularly counsels tax-exempt organizations on a wide range of matters involving governance best practices, obtaining and maintaining federal tax-exempt status, the unrelated business income tax (UBIT), excess benefit transactions (intermediate sanctions), private foundation excise taxes, and other legal requirements applicable to tax-exempt organizations.

In addition to advising tax-exempt clients on their tax and legal issues, he offers clients practical advice on navigating the challenges presented when business or mission-oriented goals conflict with the tax laws. Over the years, Shane has acted as outside general counsel for many different organizations; currently he serves in that role for The Meadows Mental Health Policy Institute for Texas.

Shane has helped a variety of tax-exempt organizations resolve tax controversies during the IRS examinations (audits), at IRS Appeals, through closing agreements, and in court. When the stakes are high, Shane teams with other law firms as co-counsel in litigation matters.

Considered by many lawyers and other professionals to be a "lawyer’s lawyer," Shane advises in-house counsel and tax departments on complex tax-exempt organization issues. He also serves as co-counsel with corporate and criminal defense lawyers in matters that involve or raise issues related to tax-exempt organizations. Shane often assists accounting firms when their nonprofit clients face unique or especially thorny tax-law issues or require representation before the IRS.

Shane is also the co-author, with Bruce Hopkins, of The Tax Law of Private Foundations, Sixth Edition and The Law of Tax-Exempt Organizations, 2024 Cumulative Supplement.

Before forming Hamilton | Vopelak P.C., Shane was a Member of Miller & Chevalier Chartered in Washington, D.C. and was the head of that firm’s tax-exempt practice group. While attending the University of Virginia School of Law, he served as an Executive Editor and the Tax Cite Editor of the Virginia Tax Review. He is a member of Phi Beta Kappa, University of Virginia.
