The United States Tax Court issued a ruling on November 10, 2026, regarding Riddle Aggregates, LLC, and its claimed charitable contributions related to a conservation easement. This decision affects Riddle Aggregates and its tax matters partner, Ornstein-Schuler, LLC, as they sought deductions totaling nearly $45 million. The ruling is significant as it clarifies the tax treatment of conservation easements, which are often scrutinized by the IRS.

The case, documented under Docket No. 31104-21, centered on a partnership-level proceeding under the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA). Riddle Aggregates claimed a charitable contribution deduction of $44,995,000 for a donated conservation easement and an additional $355,000 for a fee simple interest in property. The IRS disallowed these deductions, prompting Riddle Aggregates to contest the decision in court.

Riddle Aggregates, based in Alabama, is a limited liability company treated as a partnership for federal tax purposes. Its tax matters partner, Ornstein-Schuler, LLC, is based in Georgia. The dispute arose after the IRS issued a Notice of Final Partnership Administrative Adjustment (FPAA) on August 23, 2021, disallowing the entire conservation easement deduction and a portion of the fee simple interest deduction, along with asserting penalties.

The case was part of a larger group of 14 cases involving similar charitable contribution deductions for conservation easements, primarily in Morgan County, Alabama. The court set this case as a test case for the others, with parties in related cases agreeing to be bound by its outcome.

In its ruling, the Tax Court, led by Judge Kerrigan, found that Riddle Aggregates was entitled to the deductions it claimed. The court stated, "The fair market value of the Riddle Property after the conservation easement was granted was $345,000," and acknowledged that the conservation easement constituted a qualified conservation contribution under the tax code. The court also noted that the IRS did not apply certain penalties regarding the deductions.

The court's opinion highlighted the importance of establishing fair market value in such cases. It underscored the need for accurate appraisals and the necessity of compliance with IRS regulations regarding charitable contributions. The court ruled that Riddle Aggregates had met the substantiation requirements for its donations.

This ruling has significant implications for Riddle Aggregates and similar partnerships that engage in conservation easement transactions. It reinforces the notion that partnerships can successfully claim substantial deductions for conservation easements if they provide adequate documentation and adhere to IRS guidelines. The decision may also influence future cases involving conservation easements, as it sets a precedent for how the courts evaluate such claims.

Moving forward, the ruling may encourage more partnerships to explore conservation easement donations as a tax strategy, provided they ensure compliance with the applicable laws and regulations. The case also serves as a reminder of the complexities involved in valuing property for tax purposes, particularly in the context of conservation easements.

As for next steps, it remains to be seen whether the IRS will appeal the Tax Court's decision. The court filing did not indicate any pending related cases, but the outcome of this case could influence similar disputes in the future.
