On June 5, 2025, the United States Supreme Court (the “Court”) unanimously ruled in Catholic Charities Bureau, Inc. v. Wisconsin Labor and Industry Review Commission that a Catholic charity group was entitled to a tax exemption from the state’s unemployment fund, and that interpreting the statutory language to the contrary…

Introduction

Tax-exempt organizations, while not generally subject to tax, are subject to tax on their “unrelated business taxable income” (“UBTI”).  One category of UBTI is debt-financed income; that is, a tax-exempt organization that borrows money directly or through a partnership and uses that money to make an investment is generally subject to tax on a portion of the income or gain from that investment.[1]  However, under section 514(c)(9),[2] “educational organizations” are not subject to tax on their debt-financed income from certain real estate investments.

The Mayo Clinic in Minnesota is one of the country’s leading hospitals.  Between 2003 and 2012, the Mayo Clinic was a partner in a partnership that borrowed money to make real estate investments.[3]

On November 22, 2022, U.S. District Court for the district of Minnesota held that the Mayo Clinic qualified as an educational organization within the meaning of section 514(c)(9) and, therefore, was not subject to tax on the debt-financed income from the partnership.[4]

On July 1, 2021, the Supreme Court struck down a California donor-disclosure law as facially unconstitutional in its decision in Americans for Prosperity Foundation v. Bonta.[1]  The law required nonprofits operating or soliciting contributions in California to disclose to the Attorney General of California information about all of its donors who contribute more than $5,000 each year (generally, through a requirement that nonprofits submit a copy of their Schedule Bs from their IRS Form 990s).[2]  The decision clarified the rules applicable to disclosure requirements with respect to the First Amendment, and while the decision itself addressed nonprofit disclosures, its scope could stretch significantly beyond this area.

On March 15, 2019, the U.S. Court of Appeals for the Seventh Circuit held in Gaylor v. Mnuchin that the tax exemption for “ministers of the gospel” (defined below) under Section 107(2) of the Internal Revenue Code (the “Code”) does not violate the Establishment Clause[1] of the First Amendment…
