The United States Tax Court has ruled that the Internal Revenue Service (IRS) issued a Notice of Final Partnership Adjustment (FPA) on time to Katanga Properties, LLC. This ruling, issued on September 9, 2026, affects the LLC's tax obligations and clarifies the deadlines for IRS adjustments under the Bipartisan Budget Act of 2015.

Katanga Properties, LLC, along with its partnership representative R. Brent Evans, challenged the IRS's notice, claiming it was issued after the deadline. The court's decision confirms the IRS's authority to issue adjustments within the specified timeframes, impacting how partnerships manage their tax affairs.

Background

Katanga Properties, LLC, is a limited liability company based in Louisiana that is treated as a partnership for federal tax purposes. The company filed its 2020 tax return on June 10, 2021, and claimed a charitable contribution deduction. However, the IRS issued a Notice of Final Partnership Adjustment on March 25, 2025, disallowing this deduction.

The dispute arose when Katanga Properties filed a petition with the Tax Court, asserting that the IRS's notice was untimely. The case reached the Tax Court after the IRS and the partnership agreed to extend the limitations period for adjustments until May 30, 2025, using Form 872-M, which is a consent form to extend the time for making partnership adjustments.

The Ruling

In its ruling, the Tax Court denied Katanga Properties' motion for summary judgment, stating that the IRS's FPA was issued within the appropriate timeframe. Judge Weiler noted, "The FPA, mailed on March 25, 2025, was issued timely pursuant to section 6235(a)(1)." The court emphasized that the extension agreement signed by both parties allowed the IRS to issue the FPA within the extended deadline.

The court clarified that the statutory framework under the Bipartisan Budget Act allows for adjustments to be made as long as they fall within the latest of the established deadlines. According to the court, the IRS's issuance of the FPA was valid and did not violate any limitations set forth in the Internal Revenue Code.

Impact

This ruling has significant implications for partnerships and their tax representatives. It reinforces the importance of understanding the timelines associated with IRS adjustments, particularly under the Bipartisan Budget Act. Partnerships must be aware that extensions can affect the deadlines for notices and adjustments, which can influence their tax liabilities.

Furthermore, the decision sets a precedent for how the courts interpret the timing of IRS notices and the conditions under which they can be issued. This ruling may affect future cases involving partnerships and their tax obligations, clarifying the IRS's authority to make adjustments within stipulated timeframes.

What's Next

Details were not available in the court filing regarding whether Katanga Properties plans to appeal the decision. However, the ruling stands as a significant interpretation of tax law concerning partnership adjustments, and it may influence similar cases in the future.
