How captive insurance works
A captive is a form of self-insurance carried out through a real, regulated insurance company. The parent (or the member companies) pays premium to the captive, the captive pays covered claims, and any underwriting profit or loss stays within the ownership group. Captives are licensed in a chosen domicile, and state regulators oversee their capital, reserves and reporting. Many captives also buy reinsurance or excess coverage to protect against large losses. Unlike a commercial insurer, a captive's owners put their own capital behind the risk, and captives generally do not have the state guaranty fund protection that commercial insurers' policyholders may have.
Common structures
- Single-parent (pure) captive: insures the risks of its parent and affiliates.
- Group captive: owned by several unrelated companies that pool certain risks.
- Association captive: insures members of a trade or professional association.
- Rent-a-captive or protected cell: lets outside companies use a captive that someone else operates, with cells legally separated in the protected-cell form.
- Risk retention group: a liability-only captive formed under federal law.
Example
A mid-sized logistics company finds its commercial auto and workers' compensation premiums rising despite a clean claims record. It forms a single-parent captive, pays premium to it for a defined layer of those risks, and buys reinsurance above that layer. Good claims years may build surplus inside the captive. A bad year is still funded from the captive's capital, so the company must be ready to absorb it.
Captive insurance vs. related terms
- Retention or self-insurance. A retention is the amount a company pays itself before insurance responds. A captive is a licensed insurer that holds the premium and pays claims, so the risk is formally financed through an insurance structure.
- Commercial insurer. A commercial insurer takes risk from many unrelated buyers using its own capital. A captive's owners provide the capital and share in the results.
- Fronting and reinsurance. A fronting carrier may issue the policy so the buyer has a licensed insurer on paper, then pass the risk to the captive. The captive often buys reinsurance to protect against large losses.
- Domicile. The regulator where a captive is licensed matters. Domiciles include several US states and offshore locations, among them Bermuda, which is also discussed on the Bermuda market page.
- Umbrella or excess coverage. Umbrella and excess policies can sit above a captive's layer to provide additional limits.
A second example: a group captive
A hypothetical group of ten technology services companies of similar size joins a group captive to finance a layer of their workers' compensation and general liability losses. Each member pays premium into the captive, claims within the layer are paid from the captive's funds, and reinsurance sits above it. Members with good loss experience may benefit over time, while poor group results can mean additional contributions or collateral, depending on the structure. Before joining, each company reviews its loss runs, the capital commitment and the exit terms.
What to watch for
- A captive retains risk. It suits stable, predictable exposures better than rare, severe ones.
- Formation and ongoing costs include capitalization, actuarial and management fees, audits and regulatory filings.
- Tax treatment is a specialist area. Some small captives have drawn IRS scrutiny, so get tax counsel before relying on any tax benefit.
- Fronting carriers and reinsurers are often needed, and collateral may be required.
Why it matters for technology, AI, fintech and digital-asset companies
Most early-stage companies are too small for a captive, and coverage for new exposures is typically bought from commercial insurers. Larger or more mature hardware, fintech or data-center operators with predictable losses, especially in retentions and deductibles, sometimes evaluate captives later in their growth.
Questions to ask your broker or underwriter
- Which risks and layers would the captive retain, and how predictable are they based on loss history?
- What capital and collateral are required, and what are the ongoing costs for management, actuarial work, audits and filings?
- Which domicile and regulator would apply, and which fronting carrier and reinsurers would be involved?
- Have tax and legal advisors reviewed the structure? Tax treatment is a specialist area.
- Do customers, lenders or investors require coverage from a rated or licensed insurer, and would a captive satisfy them?
- What is the exit plan, including how remaining claims would be handled in run-off if the captive closes?
- How would the program interact with premium savings in the commercial market over a full cycle, including a hard market and a soft market?
Common mistakes
- Forming a captive mainly for a tax benefit. The arrangement still has to function as real insurance.
- Retaining unpredictable severity. A captive is better suited to frequent, measurable losses than to rare catastrophic ones.
- Underestimating costs. Capital, collateral, fees and reporting add up before any savings appear.
- Skipping an exit strategy. Closing a captive can take years if claims are still open.
- Treating a captive as a substitute for all commercial coverage. Large-loss protection usually still comes from reinsurance or excess insurance.
- Joining a group captive without reviewing how losses, collateral and extra contributions are shared.
How captives show up for fast-growing companies
Most early-stage companies are too small and their exposures too new for a captive, and they typically buy from commercial insurers. As a company matures, a captive may become relevant for stable, high-frequency lines or for large retentions. Newer exposures such as AI liability and digital assets are harder to model, so the economics are less predictable. See startup insurance by stage for how programs usually develop, hard-to-place risks for exposures where commercial capacity is limited, and cyber and tech E&O for a line where retentions and limits are commonly discussed. A captive is also not a way to avoid underwriting discipline. Any program should be built on loss data and an actuarial study.

Frequently asked questions
What is a captive insurance company?
A captive insurance company is a licensed insurer owned by the business or group of businesses it insures, used to finance and manage their own risks. Common forms include single-parent (pure) captives, group captives, and association captives.
Is a captive the same as self-insurance?
It is closely related. A captive is a self-insurance approach carried out through a licensed insurance company that the insured owns. Unlike simply setting money aside, the captive issues policies, is regulated, and can access reinsurance markets, though the owners still bear the retained risk.
Who regulates captive insurers?
Captives are typically regulated by the insurance department of the state or country where they are licensed, which sets capital, reserve and reporting requirements. Some domiciles are known for captive-specific laws. Risk retention groups are formed under federal law but are still licensed in a chartering state.
Is a captive right for a startup?
Usually not at the earliest stages. Captives need predictable losses, sufficient capital and management resources, and they retain risk rather than transfer it. Startups typically use commercial insurance, and revisit captives later if their loss experience becomes stable and large enough.
How much does it cost to form a captive?
There is no standard figure. Costs depend on the domicile, the structure, the capital required, and the service providers used for management, actuarial work and audits. A feasibility study usually precedes the decision and gives a company-specific estimate.
What is a fronting carrier and why do captives use one?
A fronting carrier is a licensed insurer that issues the policy and then cedes some or all of the risk to the captive. It gives the buyer a licensed insurer on paper, which can help meet regulatory or contract requirements. Fronting carriers typically charge a fee and may require collateral.
Are captive insurance premiums tax-deductible?
It depends on whether the arrangement qualifies as insurance for tax purposes and on how it is structured. Some small captives have drawn IRS scrutiny. Get advice from a qualified tax advisor before relying on any tax treatment.
What happens to a captive if the parent company is sold?
It depends on the structure and the deal terms. The captive may be sold with the business, kept by the seller, placed in run-off or dissolved. Planning for that outcome in advance is part of good captive governance.
