In this week’s post, we analyze the recent Tax Court case, Cecil v. Commissioner. A key issue in the case was the role of appreciated corporate assets in determining the fair market value of a minority interest in an operating company. The Cecil family has owned and operated the Biltmore mansion in Ashville, North Carolina for decades, and the case highlights the intersection of the asset-based, income, and market approaches to valuation, and serves as an important reminder to families evaluating their own estate plans in light of the approaching sunset provisions in the Tax Cut and Jobs Act of 2017.
