Definition
A captive insurer is a licensed insurance company created and owned by a business or family primarily to insure the risks of its owner, rather than to sell coverage to the general public.
A captive is a genuine insurance company — licensed by a regulatory authority, required to maintain reserves, and subject to insurance law — but its purpose is narrow: to cover risks that its parent business or family would otherwise pay premiums to a commercial insurer to cover, or simply absorb uninsured. Families with significant operating businesses, large real estate portfolios, or unusual risk profiles sometimes consider captives when commercial insurance is unavailable, very expensive, or poorly tailored to their actual exposures. A qualified attorney, CPA, and licensed insurance professional must be involved in any captive formation and ongoing operation.
Captives can be structured in various domiciles — certain U.S. states and offshore jurisdictions have developed captive-friendly regulatory frameworks — and can take different forms, including single-parent captives (owned by one business or family) and group captives (shared among related parties). Premiums paid to a properly structured and operated captive may be deductible to the operating business under rules that a tax advisor must evaluate; investment income on captive reserves may also benefit from favorable treatment in certain structures.
A critical confusion: the IRS has scrutinized captive arrangements aggressively, particularly smaller "micro-captive" structures used primarily as tax shelters rather than for genuine risk management. A captive that insures improbable or fictitious risks, or that exists mainly to generate deductible premiums, faces significant legal exposure. Distinguishing a legitimate captive from an abusive arrangement requires careful professional guidance and genuine economic substance in the insurance program.
