Quick Answers
Captive insurance had one of its busiest regulatory years in 2026. The IRS raised the annual premium cap for IRC §831(b) small-captive elections to $2.9 million. Vermont signed H.649 on , sharpening its regulations without weakening its position. Hawaii’s Senate unanimously passed a bill letting captives take on catastrophic property and casualty risk. Bermuda removed a long-standing beneficial-ownership exemption for captives. Maryland is fighting nonprofit hospitals over taxes on offshore Cayman captives. Formations keep growing. So does IRS enforcement against abusive structures.
The IRS Raised the 831(b) Cap — and Tightened the Leash
The IRS made two moves in opposite directions. It raised the 831(b) annual premium cap to $2.9 million for the 2026 tax year, preserving the inflation adjustment that small captives rely on. At the same time, regulations issued in early 2025 flagged certain abusive micro-captive structures as “listed transactions,” forcing disclosure and creating penalty exposure.
The election under Internal Revenue Code §831(b) lets a qualifying small insurance company be taxed only on investment income, not on underwriting profits. That is the tax advantage that makes small captives attractive. The new cap means a qualifying captive can receive up to $2.9 million in annual premiums while keeping the election.
The IRS is drawing a sharper line between legitimate risk financing and tax shelters dressed up as insurance. Captives that charge premiums without credible actuarial backing, cover risks that are not real, or move money back to owners through loans and circular transfers now sit inside the listed-transaction category. Disclosure is mandatory. Penalties start where disclosure stops.
The practical effect for legitimate captive owners is paperwork. Actuarial files need to be defensible. Premium pricing needs third-party support. Any transactions between the captive and its parent need to look like arm’s-length insurance dealings, not cash management.
Vermont’s H.649 Keeps the Gold Standard Gold
Governor Phil Scott signed H.649 on . The bill takes effect . Vermont licenses more than 1,400 captives and is treated as the benchmark onshore US domicile.
The law does three things. It prohibits risk retention groups from lending to, or investing in, their member-owners and affiliates. It formalises quarterly financial reporting for RRGs in line with NAIC standards. It requires protected cells to certify that funding matches their approved business plan at the moment of formation.
None of this is radically new for Vermont. The bill codifies practices the Department of Financial Regulation was already enforcing. The signal for other states, and for captive owners choosing a domicile, is that Vermont will tighten statute to match what regulators were doing anyway. Competing domiciles now face pressure to match. Vermont Business Magazine carries the full signing statement from the Governor’s office.
State Action: Hawaii, Tennessee, and Maryland
Hawaii wants captives for hurricane and wildfire risk
Hawaii’s Senate unanimously passed a bill in March 2026 allowing captives licensed in the state to underwrite, reinsure, or assume catastrophic property and casualty risks. State insurance regulators opposed the measure. The bill has advanced to the House. If it becomes law, Hawaiian captives will be able to take on hurricane, wildfire, and similar tail-risk exposures that commercial insurers price heavily or exclude outright.
Tennessee reports a sixth year of captive growth
The Tennessee Department of Commerce and Insurance announced its sixth consecutive year of growth in active cells and risk-bearing entities. Tennessee has become a more active competitor for US captive formations, particularly in group captives and protected cell structures. Municipal captives — government-owned structures for property risks — are a notable formation category this year.
Maryland is fighting nonprofit hospitals over offshore captives
Maryland’s legislature is debating SB 890, which would pause state tax collection for two years on offshore captive premiums held by nonprofit hospitals. A whistleblower told lawmakers that between $1.7 billion and $3 billion of Maryland nonprofit hospital funds sit in Cayman-based captives. The dispute centres on whether those hospitals should have been paying state premium taxes on out-of-state insurance for years. Economic policy advocates want the bill killed. The outcome will set a precedent for how aggressively other states audit nonprofit captive structures. Maryland Matters has detailed committee coverage.
Bermuda Ends the Captive Exemption on Beneficial Ownership
Bermuda’s Beneficial Ownership Act 2025 removes the exemption that let captive insurers keep ownership details out of the public beneficial-ownership register. The change aligns Bermuda with international transparency standards pushed by the OECD and the Financial Action Task Force.
Captive boards now need to review their ownership disclosures. Some Bermuda captives were formed specifically because the exemption existed. Boards that assumed the exemption would continue must decide whether to disclose, restructure, or redomicile to a jurisdiction with lighter reporting. Cayman, Guernsey, and newer European domiciles — Italy in particular — are already fielding the inquiries.
The OBBBA’s Ripple Effects
The One Big Beautiful Bill Act was signed on . It did not mention captives directly. Its indirect effects are reshaping how captives are used in 2026.
Healthcare: more pressure toward self-funding
The law expanded Health Savings Account eligibility beyond high-deductible plans for 2026 and raised contribution limits to $4,400 for individuals and $8,550 for families. It also reduced federal Medicaid funding by an estimated $1 trillion over ten years. The Congressional Budget Office projects more than 11 million people losing coverage over that period. Employers that self-fund medical benefits — often through captives — are planning for higher enrolment and higher claim exposure. Medical stop-loss captives are the main beneficiaries.
Tariffs: trouble for international captives
The law introduced tariff measures that Swiss Re projects will slow global GDP growth and cut insurance premium growth. For captives domiciled offshore, the tariffs complicate transfer pricing and raise double-taxation risk. International captive structures built on stable cross-border tax assumptions need a fresh legal review. Captive International’s analysis sets out the transfer-pricing exposures in detail.
What’s Driving Captive Growth in 2026
Three pressures keep pushing formations up.
The commercial market is still hard
Liability, property, and cyber premiums remain elevated. Organisations looking at renewals are finding it cheaper to retain more risk and buy less commercial cover. Captives let them do that formally, with tax-deductible premiums and build-up of reserves that sit on a controlled balance sheet.
Litigation risk is rising
Nuclear verdicts — single-defendant awards of $10 million or more — plus social inflation and third-party litigation funding are inflating claims severity. Transportation, healthcare, and construction are most exposed. Captives let companies fund that volatility across years rather than absorbing it in a single renewal.
Emerging risks have no home in the commercial market
Cyber, supply chain, climate, and certain cannabis-industry exposures are either not written by mainstream insurers or are written at prohibitive prices. Captives fill the gap. The Iowa Insurance Division, the Tennessee Department of Commerce and Insurance, and Milliman’s captive practice have each forecast continued growth into 2026, citing the same drivers.
What This Means for Your Business
If you already own a captive
Three things need attention this year. Your actuarial file must be defensible under the IRS listed-transaction standard. Your domicile filings must match new requirements — Vermont’s quarterly RRG filings, Bermuda’s beneficial-ownership disclosures, Hawaii’s expanded capacity if the bill passes. Your transfer-pricing documentation needs a tariff review if you operate offshore.
If you are considering one
The decision window has improved. The higher 831(b) cap, a competitive domicile market, and a hard commercial market all tilt the economics toward captives. The decision still rests on one question: does your business generate enough risk volume and loss predictability to justify the formation cost and the compliance load?
Captive managers typically cite $500,000 to $1 million in annual commercial premium as a working threshold. Below that, a rental cell or a group captive usually makes more sense than a standalone pure captive. Above it, the numbers start to work in your favour within two to three years.
Your 2026 Captive Owner Checklist
If your business runs a captive or sits inside a protected cell, these items are worth clearing this year.
- Request an updated actuarial memorandum reflecting the $2.9 million 831(b) premium limit.
- Review your captive’s risk profile against the IRS listed-transaction indicators for abusive micro-captives.
- If domiciled in Vermont, confirm RRG quarterly financial filings match the H.649 format before .
- If domiciled in Bermuda, update beneficial-ownership disclosures under the 2025 Act.
- If operating internationally, ask tax counsel for a transfer-pricing review in light of OBBBA tariff measures.
- If based in a state with new legislation (Hawaii, Maryland), monitor the bill status and model the tax or coverage implications.
- Benchmark your captive’s investment policy against rising reinsurance costs and the hard commercial market.
Bottom Line
2026 is not a year of dramatic rewrites. It is a year of tightening. IRS scrutiny is sharper. Bermuda transparency is broader. Vermont filings are more formal. Against that, the $2.9 million cap and Hawaii’s catastrophic-risk bill expand what captives can do. Growth continues because the commercial market and litigation trends give business owners no better option. If you sit inside a captive structure or are considering one, the cost of inattention in 2026 is higher than it was three years ago.
