Captive Insurance
Insurance subsidiary created by a company to insure its own risks rather than purchasing coverage externally.
Captive insurance is a form of self-insurance in which a company creates and owns a licensed insurance subsidiary to provide insurance coverage for the parent company's risks, rather than purchasing all coverage from commercial insurers. The captive insurer collects premiums from the parent (or affiliated entities), accumulates reserves, and pays covered claims—keeping the insurance economics within the corporate family.
Captive types: single-parent (pure) captives (owned entirely by one parent company, insuring only that parent's risks); group captives (owned by multiple companies in the same industry, pooling risks for cost reduction); association captives (sponsored by a trade or professional association for its members); rent-a-captive (using the capital and infrastructure of a third-party captive facility without owning a standalone captive); and cell/protected cell companies (PCCs—separate cells within a single licensed entity, each with ring-fenced assets).
Captive benefits: premium stabilization (avoiding commercial market volatility and underwriting cycle impact); access to reinsurance markets (captives can purchase reinsurance directly at wholesale rates); coverage customization (writing coverages unavailable or expensive in the commercial market—e.g., cyber retentions, product recall, supply chain disruption); claims management control (managing claims according to the parent's philosophy); profit retention (underwriting profits and investment income stay within the corporate group); and potential tax benefits (deductions for premiums paid to captives meeting specific IRS requirements).
Captive domiciles include Vermont (largest U.S. domicile), Delaware, Cayman Islands, Bermuda, Guernsey, and over 70 other jurisdictions. Captive feasibility requires typically $5M+ in premium volume and adequate capital. IRS scrutiny of micro-captives and 831(b) abusive tax shelter arrangements has been an ongoing enforcement priority.
FAQs
What are the minimum premium requirements to justify forming a captive?
Captive formation is generally economically justified when annual premium volume for the risks to be insured reaches $5M–$10M+, depending on captive structure and domicile. Below this threshold, captive administrative costs (actuarial services, captive management fees, auditing, regulatory filing, domicile fees) consume too large a percentage of premiums to justify the structure over simpler alternatives like higher deductible programs. Group captives and rent-a-captive structures lower this threshold significantly—companies with $1M–$3M in premiums can access captive economics through participation in group structures without the overhead of a standalone captive.
What is an 831(b) captive election and why has the IRS targeted it?
An 831(b) captive makes an election under IRC Section 831(b) to be taxed only on investment income (not underwriting income) if premiums are below $2.65M (2024 threshold). Legitimate 831(b) captives insure real, hard-to-place risks and accumulate reserves appropriately. The IRS has aggressively pursued abusive 831(b) micro-captives designed primarily as tax shelters: the parent pays premiums to a captive owned by family members or trusted individuals, which are deducted as business expenses; the captive pays little in claims; the arrangement generates large underwriting 'profits' that can be distributed tax-advantaged. Thousands of such arrangements have been challenged as listed transactions or transactions of interest, resulting in tax penalties and back taxes for participants.
What types of risks are most commonly placed in captives?
Captives most commonly cover: workers' compensation retentions (large employers retain the first layer of WC losses, using captives to formally structure the retention); general and products liability retentions (particularly for companies with claims history that makes commercial coverage expensive); professional liability (medical malpractice, E&O); property retentions (SIR layers below commercial coverage); employee benefits (health stop-loss, wellness programs, dental); specialty coverages unavailable commercially (supply chain interruption, reputational damage, political risk in specific markets); and cyber insurance retentions (growing rapidly as commercial cyber premiums increase). The unifying theme: risks where the parent has better information than commercial underwriters, expects favorable long-term claims experience, or values the coverage customization control that captives provide.
