Captive insurance companies (CICs) allow businesses to retain insurance risk and profits to build wealth in a tax-advantaged manner. CICs are owned by their policyholders, typically a single company or business owner. By establishing a CIC, businesses can deduct insurance premiums paid to the CIC to reduce taxes, while the CIC receives the premiums tax-free and invests the funds to grow further. A CIC can be an effective estate planning tool by shifting wealth out of an owner's estate to heirs through the use of an irrevocable trust.
