Captive domiciles compared: Vermont, Utah, Delaware and offshore

A captive's domicile is the state or country that licenses it and supervises it for as long as it exists. Choose it on the regulator's competence, the capital and tax it requires, the depth of local service providers and whether your fronting carrier is comfortable, not on a promised tax result: the federal income tax tests are the same for every U.S. domicile. Vermont is the largest U.S. domicile, Utah, Delaware and Tennessee are the other big onshore choices, and the Cayman Islands and Bermuda lead offshore.

The mechanics of the captive itself are in what is a captive insurance company and how does it work?. This guide is about where to put one.

What a domicile actually controls

The domicile's insurance department, not your home state's, decides:

• Whether your structure is licensable. Pure, association, industrial insured, sponsored (cell) and risk retention group captives are separate license types, and not every domicile offers all of them. See cell captives and protected cell companies: how renting a cell works and Risk retention groups (RRGs): how they work and what to check.
• Minimum capital and surplus. For example, Vermont's statute, 8 V.S.A. § 6004, sets $250,000 for a pure captive, $500,000 for an association or industrial insured captive, $100,000 for a sponsored captive and $1,000,000 for a risk retention group.
• Annual premium tax. Vermont taxes direct premiums at 0.38% on the first $20 million, 0.285% on the next $20 million, 0.19% on the next $20 million and 0.072% above that, with a minimum of $7,500 and a maximum of $200,000 a year (8 V.S.A. § 6014).
• Reporting, audit and actuarial requirements, examinations, dividend and investment limits, and how fast an application moves.
• Local presence rules. Captives usually need a resident manager and a registered office, and some domiciles require board or annual meetings in person. Utah's captive director said in September 2026 that its in-person annual meeting requirement will be enforced, with a fee of at least $5,000 for captives that neither attend nor join the state captive association at the level that waives it.

The main domiciles, with the latest figures

Counts differ because regulators count differently: some include cells and series, some do not, and some count active licenses while others count all licensed entities. Treat these as scale indicators, not a ranking.

The Business Insurance ranking (reported by Captive.com on May 5, 2025) put Vermont at 683 licensed captives at year-end 2024, Utah at 462 and Guernsey at 197, and excludes micro-captives, series captives and cells within protected cell companies. The NAIC's captive page says more than 70 jurisdictions have some form of captive legislation, so these six are the busiest, not the only ones.

Onshore or offshore

A U.S.-domiciled captive is generally a domestic corporation for federal tax purposes. An offshore captive is a foreign corporation unless it elects otherwise, and U.S. owners face extra rules.

• Section 953(d). A foreign insurer with substantial U.S. ownership can elect to be treated as a U.S. domestic corporation, if it would qualify as an insurance company under subchapter L and meets Treasury's other conditions, including a waiver of treaty benefits. Many offshore captives owned by U.S. businesses make this election.
• Federal excise tax. Under IRC § 4371, premiums paid to a foreign insurer carry a 4% federal excise tax on casualty insurance and indemnity bonds, and 1% on reinsurance. Treaties and exceptions exist, so confirm with your tax advisor.
• Scrutiny. The IRS looks at the facts of the arrangement, not the flag. Avrahami, an early micro-captive loss in the Tax Court, involved a captive set up in St. Kitts, but the court's decision turned on risk distribution and its findings about the reinsurance pool and pricing, and the same tests apply onshore. Micro-captives (831(b)) and the IRS: rules, red flags and reporting explains.
• Why use offshore anyway. Bermuda and the Cayman Islands have deep reinsurance and management communities and suit multinational or large corporate programs that do not need a U.S. license.

Most small and mid-sized U.S. captives choose a U.S. domicile for simplicity: one legal system, familiar auditors and regulators who talk to fronting carriers every day.

Your own state still has a say

Putting the captive in Vermont does not exempt you from your own state. Under the federal Nonadmitted and Reinsurance Reform Act, 15 U.S.C. § 8201(a), "no State other than the home State of an insured may require any premium tax payment for nonadmitted insurance." Your home state may therefore tax premiums you pay to an out-of-state captive in the way it taxes independently procured nonadmitted insurance, on top of the domicile's own premium tax. Rates and exemptions vary by state, and the topic overlaps with surplus lines taxes, stamping fees and diligent search, so ask your broker or tax advisor what applies to your state before you model savings.

A hypothetical premium tax calculation

Using Vermont's schedule, a captive writing $2 million of direct premium owes 0.38% of that, which is $7,600. A captive writing $500,000 would calculate $1,900 but pay the $7,500 minimum. A captive writing $50 million would owe $76,000 on the first $20 million, $57,000 on the next $20 million and $19,000 on the last $10 million, a total of $152,000. These figures are an arithmetic illustration of the statute, not a quote for any program; other domiciles use different schedules, and premium taxes are a minor part of the budget next to service fees and collateral.

How to choose

1. Start with your fronting carrier and reinsurers. Some are more comfortable with particular domiciles. See fronting arrangements and fronting carriers: how they work.
2. Confirm the license type exists for your structure, and whether the domicile has experience with it.
3. Price the minimum capital, premium tax, annual fees and any in-person requirements at your expected premium.
4. Ask who the resident service providers are and how many captives of your type they manage. A deep local bench shortens licensing and annual filings.
5. Ask the regulator about timing. A feasibility study is only as useful as the licensing calendar behind it.
6. Check redomestication rules. Many domiciles allow a captive to move, so the first choice is not permanent, but moving takes approvals and fees from both regulators.
7. Run the answer past tax counsel for the home-state tax and any foreign-parent consequences.

The business case comes first. If the numbers do not support a captive in the cheapest domicile, a different domicile does not fix them; see Is a captive right for your business? A feasibility checklist and the structure comparison in single-parent vs group captives: which structure fits?.

Key takeaways

• The domicile licenses, capitalizes and audits the captive, but it does not change federal income tax treatment for a U.S. captive.
• Vermont (707 licensed captives at year-end 2025), Utah, Delaware and Tennessee are the largest U.S. choices; Cayman and Bermuda dominate offshore. Counts vary by definition and date.
• Offshore captives owned by U.S. businesses bring section 953(d) choices and the 4% federal excise tax on casualty premiums.
• Your home state can still tax premiums paid to an out-of-state captive, so add that to the cost model.
• Pick the domicile after the feasibility study and the fronting arrangement, not before.
