Tennessee Court Backs IRS Micro-Captive Reporting Regulations

A federal court in Tennessee has upheld the Internal Revenue Service (IRS) final micro-captive reporting regulations, rejecting a challenge by CIC Services LLC and leaving the agency's disclosure framework for certain Section 831(b) captive transactions in place.

In a March 5 opinion, the US District Court for the Eastern District of Tennessee granted summary judgment to the IRS, the Treasury Department, and related defendants, while denying CIC's motion. The ruling is the latest development in CIC's long-running dispute with the government over federal oversight of micro-captive insurance arrangements.

CIC, a Knoxville-based firm that helps businesses establish and manage captive insurers, argued that the final rule exceeded the IRS's statutory authority and violated the Administrative Procedure Act. The company also contended that the regulations effectively imposed additional requirements on captives seeking the tax election available under Internal Revenue Code Section 831(b).

Judge Travis R. McDonough rejected those arguments. The court held that the final rule and accompanying regulations do not alter the statutory requirements for making a valid Section 831(b) election and do not eliminate the tax treatment available to qualifying small insurance companies. Instead, the opinion said, the regulations establish reporting and record-keeping obligations for transactions the IRS believes may present a risk of tax avoidance.

That distinction was central to the court's analysis. According to the opinion, the regulations are disclosure rules rather than substantive limits on the use of Section 831(b). A captive insurer that meets the statutory requirements may still elect Section 831(b) tax treatment even if its structure falls within the reporting framework for listed transactions or transactions of interest.

The case stems from the IRS's earlier effort to monitor micro-captive arrangements through Notice 2016–66, which classified certain transactions as "transactions of interest." CIC challenged that notice in federal court, and in 2022 a judge invalidated it after finding that the IRS had failed to follow the notice-and-comment procedures required under the Administrative Procedure Act.

Following that ruling, the Treasury Department and the IRS initiated formal rulemaking and ultimately issued final regulations in January 2025. Those regulations identify certain micro-captive arrangements as either listed transactions or transactions of interest, triggering disclosure requirements for taxpayers and material advisors.

Under the rule, certain Section 831(b) captive arrangements may be classified as listed transactions based on factors involving ownership relationships, financing arrangements, and loss ratio thresholds. Other arrangements may be designated as transactions of interest if they meet related criteria the IRS believes may signal potential tax avoidance.

The court found that the IRS acted within the authority granted by Congress to require disclosure of transactions with potential for tax abuse. The opinion emphasized that the Internal Revenue Code gives the agency broad power to collect information needed to administer the tax system and identify transactions that warrant further scrutiny.

Judge McDonough also accepted the IRS's explanation for the rule's screening factors, including the loss ratio factor, financing factor, and 20 percent relationship test used to identify transactions subject to additional reporting. The court concluded the agency had reasonably explained how those factors could help identify arrangements with a higher risk of tax avoidance.

The court also rejected CIC's argument that the rule was arbitrary and capricious. Unlike the earlier notice, the final rule was supported by an administrative record that included multiple Tax Court decisions involving micro-captive arrangements that judges concluded did not constitute insurance for federal tax purposes. The opinion cited cases such as Avrahami, Syzygy Insurance Co., Caylor Land & Development, Keating, Swift, Patel, and Royalty Management Insurance Co. as examples supporting the IRS's concern that some captive structures may be used primarily for tax avoidance.

CIC further argued that the regulations were a pretext for discouraging legitimate use of Section 831(b). The court rejected that claim, finding that the administrative record supported the government's stated objective of gathering information to distinguish valid captive insurance arrangements from potentially abusive transactions.

As a result of the ruling, the court denied CIC's motion for summary judgment and granted summary judgment in favor of the government, leaving the final micro-captive reporting regulations in effect.
