What this topic is
A captive is a licensed insurance company owned by the businesses it insures. Instead of paying premium to a commercial carrier and never seeing it again, the group pays premium to its own carrier, which pays claims from reserves, buys reinsurance above a chosen attachment point, and keeps whatever underwriting profit and investment income remain.
Why it matters
A commercial premium is expected losses plus a load: acquisition costs, administration, a risk margin, the carrier's profit, and premium tax. On predictable, well-controlled risk that load can be a large share of the bill. A captive lets a company keep it, in exchange for keeping the volatility, funding regulatory capital, and running a real insurance company with real filings.
Who should learn it
Owners and finance leads with meaningful, stable insurable losses, several years of clean claims data, and a genuine risk-financing reason, plus anyone who has been pitched a captive and wants to test the pitch.
What you will understand
- Trace the money: premium, reserves, reinsurance, fronting, collateral, surplus
- Separate the four structures: single-parent, group, cell, and risk retention group
- Price the load you would be keeping, against the cost of running the company
- Apply the tax test courts actually use: risk shifting and risk distribution
- Recognize a promoter-driven structure before you fund it
Prerequisites
Common misconception
"A captive is a tax strategy." A captive is a risk-financing structure that has tax consequences. The distinction is not academic: the deduction only exists if the arrangement is insurance for federal tax purposes, and courts have repeatedly held that arrangements built for the deduction are not.[1][4] The working diagnostic is simple and unforgiving. If the tax treatment were exactly neutral, would you still form it? If no, you are not looking at a captive. You are looking at a deduction with paperwork.
