Micro Captive insurance arrangements structured under IRC § 831(b) have gained attention in recent years as business owners look for ways to manage emerging risks not typically covered by commercial carriers. Alongside this growth, the IRS and U.S. courts have continued to evaluate how these structures are formed, operated, and documented.
Below is an overview of the key court cases, dates, trends, and takeaways that help illustrate how the landscape is evolving. This information is educational only and should not be interpreted as legal or tax advice.
Key Court Cases That Continue to Shape 831(b) Compliance
Avrahami v. Commissioner (2017)
One of the earliest and most referenced micro captive cases, Avrahami highlighted several concerns the court deemed problematic, including:
- Premiums significantly higher than comparable commercial coverage
- Unclear and contradictory policy language
- A pooling arrangement that did not distribute risk adequately
- Claims not paid until after an IRS audit
- Loans from the captive back to related parties
This case helped define what courts consider “insurance in the commonly accepted sense.”
Caylor Land & Development, Inc. v. Commissioner (2021)
This case reaffirmed earlier concerns seen in microcaptive litigation, including premiums aligned with tax thresholds and inadequate risk distribution. Courts also highlighted operational irregularities and the importance of actuarially supported pricing.
Syzygy Insurance v. Commissioner (2019)
This decision expanded on the importance of arm’s‑length practices. Findings included:
- Circular flow of funds
- Questionable actuarial methodology
- Policies issued after coverage periods ended
- Lack of claims submission despite known losses
- Investments inconsistent with an insurance company’s obligations
The court also clarified what “actuarially determined premiums” should involve.
Reserve Mechanical Corp. v. Commissioner (2018; affirmed May 2022)
The case focused on an “illusory” risk pool and found that the captive did not distribute risk. The appellate court affirmed in 2022, reinforcing its significance. Abuses included:
- Arrangement by PoolRe was illusory
- Coinsurance agreement “Wholly unreasonable”
- Did not pay claims
- Lacked Investigation or supporting documentation
Puglisi Egg Farms v. Commissioner (IRS Concession, 2021)
One of the most notable outcomes in the industry—not because the court ruled for the taxpayer, but because the IRS conceded the case, avoiding a taxpayer‑friendly precedent.

Recent Wave of Cases (2024–2025): Reinforcing Familiar Themes
The last two years have seen a surge of new cases, but the themes remain consistent.
Keating v. Commissioner (January 2024)
The taxpayers, shareholders of Risk Management Strategies, Inc. (RMS), established Risk Retention, Ltd. (RR), a captive insurer domiciled in Anguilla. The court determined that RR did not operate as a bona fide insurance company. Issues included retroactive policy issuance, premiums set to maximize tax benefits, and improper claims handling.
Patel v. Commissioner (November 2025)
Drs. Patel and McAnally-Patel, owners of an eye surgery center and research facilities, established two captives: Magellan Insurance Company in St. Kitts and Plymouth Insurance Company in Tennessee. The court concluded that these captives failed to distribute risk adequately and did not function as legitimate insurance entities. Premiums were deemed unreasonable, and the captives lacked proper actuarial analysis and claims history.
Royalty Management Insurance Co. v. Commissioner (September 2024)
The court ruled against Royalty Management Insurance Co., a micro-captive insurer, finding that it did not operate as a bona fide insurance company. Issues included circular cash flows, lack of actuarial input in setting premiums, and absence of claims payments. The court emphasized the importance of genuine risk transfer and distribution in qualifying as insurance for tax purposes
Common Themes Across Court Decisions
Although each case is fact‑specific, several recurring patterns appear:
1. Premiums must be grounded in credible actuarial analysis. Courts consistently scrutinize whether pricing reflects genuine risk—not statutory limits.
2. Risk distribution must be meaningful. Participating in a pool alone is not enough; the pool must transfer real, unrelated risk.
3. Policies and claims must mirror standard insurance practices. Late policies, informal claims handling, and undocumented settlements raise red flags.
4. Captives must operate as true insurance companies. This includes capitalization, documentation, governance, reporting, and investment practices.
5. Economic substance matters. Courts look closely at the business purpose and real‑world function of the captive.
Divergent Outcomes: 2025’s Two Most Important Micro Captive Decisions
Although many recent cases have reinforced prior outcomes, 2025 delivered two decisions with dramatically different reasoning — despite both resulting in IRS wins. Together, they offer the clearest picture yet of how courts view 831(b) captives.
1. Swift v. Commissioner – Fifth Circuit Court of Appeals (July 2025)
Dr. Bernard Swift, owner of Texas MedClinic, formed two micro-captive insurers, Castlerock and Stonegate, domiciled in St. Kitts. The court found that these captives failed to meet the criteria of insurance in the commonly accepted sense and lacked sufficient risk distribution. Notably, the captives participated in reinsurance pools with circular fund flows and had premiums set without actuarial support.
Key Points:
- IRS win upheld — deductions denied and penalties applied
- Court found failed risk distribution, holding that patient visits ≠ independent third‑party exposures
- Court found failed risk distribution, holding that patient visits ≠ independent third‑party exposures
Implication: Even well‑structured captives may fail if their exposure base does not meet the appellate court’s standard for unrelated risk.
2. CFM Insurance, Inc. v. Commissioner – U.S. Tax Court (August 2025)
Trial‑level decision — persuasive but not binding outside the case
Key Points:
- First case where the Tax Court accepted that a captive met risk distribution and actuarially reasonable premiums
- Still an IRS win due to operational failures:
- Late policy issuance
- Informal claims processes
- Off‑schedule premium payments
- Shows the Tax Court may recognize well‑run, well‑documented captives as legitimate
Implication: Tax Court may be open to taxpayer wins—if operational compliance is strong.
Key Lesson From These Conflicting Outcomes
Even when courts reach different conclusions or use different reasoning:
Risk Distribution + Operational Compliance = Critical
A captive can have strong actuarial support and still fail if it lacks day‑to‑day insurance discipline…
or it can have robust operations but still fail if it cannot demonstrate genuine unrelated risk.
Both pillars matter.
Businesses exploring micro captives should understand these themes and seek guidance from experienced advisors—particularly given how consistently the IRS has prevailed in litigation during 2024–2025.
Regulatory Challenge: Drake Plastics Ltd. Co. & SRA 831(b) Admin v. IRS (April 2026)
U.S. District Court, Southern District of Texas | Senior Judge Lee H. Rosenthal | Civil Action No. H-25-2570
Unlike the compliance cases above — which address whether specific captive arrangements qualify as legitimate insurance — this case challenged the IRS’s authority to regulate the entire micro-captive industry through a January 2025 final rule. SRA 831(b) Admin funded and joined as a co-plaintiff alongside Drake Plastics Ltd. Co. and Drake Insurance Co.
What was at stake: The final rule created two tiers of reporting requirements for micro-captive transactions. The first tier — “transactions of interest” — required disclosure filings. The second tier — “listed transactions” — placed micro-captives in the same regulatory category as known tax shelters, carrying penalties up to $200,000 with no IRS discretion to waive them.
The court’s ruling was split:
- “Transactions of interest” designation (§ 1.6011-11) — upheld. The court found the IRS has authority to require disclosure from micro-captive transactions because they present a potential for tax avoidance. The reporting requirement, loss ratio thresholds, and financing factor were all found reasonable and reasonably explained.
- “Listed transaction” designation (§ 1.6011-10) — struck down and vacated. The court found the IRS failed to make the statutorily required finding that transactions covered by the rule are presumptively tax-avoidant — meaning more likely than not to be used for tax evasion. Identifying common features of abusive transactions is not the same as proving most transactions with those features are abusive. The court vacated the rule and remanded to the IRS. The vacatur takes effect May 1, 2026.
Why this matters: The “listed transaction” label was the single most damaging regulatory threat to the legitimate micro-captive industry. It carried severe financial penalties, eliminated IRS discretion to waive them, and created reputational harm that deterred business owners and their advisors from using a congressionally authorized risk management tool. Removing that designation is a meaningful protection for the thousands of businesses that use 831(b) plans to manage genuine risk.
What it does not change: Micro-captive transactions remain classified as “transactions of interest” and still require disclosure. The court was clear that the IRS has broad authority to collect information — what it cannot do is treat legitimate transactions as presumptive tax fraud without the data to back that up.
Implication: This ruling constrains the IRS’s ability to categorize entire industries as presumptively abusive without evidentiary support. It is also one of the first significant tax-regulation decisions applying the Supreme Court’s Loper Bright framework, which limits deference to agency interpretations. The IRS may attempt to re-promulgate the listed transaction rule with a stronger evidentiary record, but the court signaled that would likely require substantially different criteria.
Update: SRA and Drake Plastics Appeal the “Transaction of Interest” Designation — Fifth Circuit (May 2026)
Following the April 15 district court victory, SRA and Drake Plastics filed an appeal in the Fifth Circuit seeking to overturn the portion of the ruling that upheld the IRS’s “transaction of interest” designation for certain 831(b) arrangements.
While the district court struck down the more severe “listed transaction” label, the appeal argues that the remaining disclosure requirement has the same underlying legal and procedural problems. The appeal contests the portion of the judgment that upheld the IRS’s transaction of interest regulatory designation and argues that the same legal and procedural deficiencies identified by the court apply to the broader rulemaking framework.
Van Carlson, founder and CEO of SRA 831(b) Admin, stated: “The IRS should not have the authority to single out legitimate risk management strategies through regulatory shortcuts. This appeal is about finishing the job and ensuring small businesses are no longer unfairly targeted for using 831(b) Plans as intended, as a tool for managing risk.”
What this means: The district court win removed the most damaging regulatory label — one that caused lenders to deny financing and CPA firms to refuse tax return preparation for otherwise compliant business owners. This appeal takes the challenge further, arguing that even the lower-tier disclosure requirement lacks sufficient legal foundation. The case now moves to the Fifth Circuit Court of Appeals, which will have the final word on both designations unless the matter is taken further.
Broader context: This appeal is unfolding alongside a circuit split. The Sixth Circuit’s Eastern District of Tennessee upheld the full IRS rule in a separate case (CIC Services v. IRS, March 2026), while the Southern District of Texas vacated the listed transaction portion in Drake Plastics. That split makes Fifth Circuit review particularly significant — it could either widen or resolve the disagreement between courts on how much authority the IRS has to regulate the micro-captive industry through rulemaking.
