What is Captive Insurance?

How does captive insurance work?

A captive insurance company is a licensed insurer wholly owned and controlled by the organization it insures, known as the parent. The parent capitalizes the captive, which then issues policies, collects premiums and pays claims for some or all of the parent’s risk. Because the captive is regulated in a domicile, a province, state or jurisdiction that licenses and oversees captives, it operates under formal insurance regulatory requirements, not as an informal internal risk fund.

In practice, the captive functions much like a traditional insurer on a smaller scale. It sets premiums based on the parent’s actual loss experience rather than broad market pricing, holds reserves to pay future claims and may purchase reinsurance to limit its own exposure to large or catastrophic losses. For coverage lines that require an admitted insurance policy, such as most workers’ compensation programs, the captive often works through a fronting insurer. This licensed carrier issues the paper policy while the captive assumes the underlying risk.

This structure gives the parent organization direct visibility into its own claims data and loss trends, which most traditional insurance arrangements do not provide. Organizations that use this visibility to strengthen safety programs and claims management often see that discipline reflected in more favourable captive performance over time.

What are the different types of captive insurance companies?

Captive structures vary based on ownership, the number of participating organizations, and how much of the underwriting risk each captive assumes. Choosing the right structure depends on an organization’s size, industry and appetite for retained risk. The most common types include single-parent captives, group captives, rent-a-captives, and protected cell captives.

• Pure captive (single-parent captive). Wholly owned by one organization, insuring only that organization’s risk. This structure offers the most control but requires the highest capital commitment.
• Group or association captive. Owned by multiple unrelated organizations, often within the same industry or trade association, that pool risk and share underwriting results. This structure lowers the capital barrier for mid-sized organizations.
• Rent-a-captive. Allows an organization to access captive insurance benefits by renting capacity from an existing captive facility instead of forming and capitalizing its own entity.
• Protected cell captive (PCC). A single legal entity divided into segregated cells, each holding its own assets and liabilities. Organizations use a cell to participate in captive insurance without exposure to other cell owners’ losses.
• Agency or sponsored captive. Formed and managed by an insurance agency, broker or program manager on behalf of multiple client organizations, typically targeting a specific industry or coverage line.

What industries and organizations use captive insurance?

Captive insurance suits organizations with a large enough premium spend, a stable loss history and the internal risk management maturity to actively manage retained risk. Healthcare systems, construction firms, transportation companies, manufacturers, professional services firms and private equity portfolio companies represent some of the most active captive users, particularly for lines like general liability, professional liability and workers’ compensation.

Non-profits and municipal entities also use group captives to access coverage that may be limited or expensive in the traditional market, such as liability coverage tied to specialized programs or services. Across industries, the common thread is an organization willing to trade some risk transfer for greater control over coverage design, pricing and claims outcomes.

What are the benefits of forming a captive insurance company?

Organizations form captives to gain more control over insurance costs, coverage terms and claims data than the traditional market typically allows. Because the captive is owned by the organizations it insures, underwriting decisions and pricing reflect actual risk performance rather than broad market conditions. Among the benefits of a captive are:

• Customized coverage. Captives can underwrite risks, terms or exclusions that traditional carriers may not offer, including coverage for emerging exposures.
• Cost control over time. Premiums track the organization’s own loss experience, which rewards strong risk management with more stable long-term costs.
• Direct reinsurance market access. Captives can purchase reinsurance directly, often at more favourable terms than an organization could secure independently.
• Investment income. Reserves held by the captive generate investment income that traditional insurers would otherwise retain.
• Claims transparency. Organizations gain direct access to loss data, supporting faster, more informed risk management decisions.

Is captive insurance the right fit for an organization?

Captive insurance tends to fit organizations with meaningful annual premium spend, a consistent and analyzable loss history and a genuine commitment to active risk management. Organizations without sufficient scale or risk management infrastructure may find the capital commitment and compliance obligations outweigh the benefits.

Beyond premium size, fit depends on risk appetite. Because the parent retains more risk through the captive, leadership needs comfort with variability in claims outcomes from year to year, balanced against the long-term cost and control advantages. Industries with specialized or hard-to-place coverage needs, such as professional liability for certain sectors or coverage for unique operational exposures, often find captives especially valuable because traditional market options are limited or expensive.

What should organizations evaluate before forming a captive?

Forming a captive involves a formal evaluation and setup process, distinct from simply deciding a captive is a good fit. A feasibility study, typically conducted by an actuary, models projected losses, premium levels and capital requirements to confirm the numbers support the structure.

Key evaluation areas include:

• Domicile selection. Onshore domiciles, such as Vermont, Delaware and North Carolina, and offshore domiciles, such as Cayman and Bermuda, differ in regulatory requirements, tax treatment and formation costs.
• Capitalization and collateral. Domiciles set minimum capital requirements, and some coverage lines require additional collateral to satisfy fronting insurers or regulators.
• Service provider team. A captive typically requires a captive manager, broker, actuary, auditor and legal counsel with captive-specific experience.
• Governance structure. Organizations need a board or committee responsible for ongoing captive oversight, financial reporting and regulatory compliance.
• Regulatory and tax compliance. Captives face ongoing provincial or state regulatory examinations and specific federal tax considerations that require specialized guidance.

How is captive insurance regulated and taxed?

Captive insurance companies are regulated primarily at the province, state or jurisdiction level, where each domicile sets its own licensing, capital and reporting requirements. In the U.S., states with established captive insurance frameworks maintain dedicated regulatory divisions to oversee formation, ongoing solvency and annual reporting.

Federal tax treatment adds another layer of complexity.  Some smaller captives elect taxation under Internal Revenue Code Section 831(b), which lets a qualifying captive exclude its underwriting income from federal income tax and be taxed only on its investment income. The Internal Revenue Service (IRS) has increased scrutiny of certain micro-captive arrangements in recent years, and has moved to treat some reportable transactions, making qualified tax and legal guidance essential before pursuing this election.
