Captive insurance companies allow businesses to insure their own risks. There are tax benefits to using a captive insurance company, including deducting premium payments and not paying tax on investment income up to certain thresholds. For example, a company formed a captive insurance company owned by shareholders to provide employee medical and disability insurance. This allowed a tax deduction for premiums and no tax on the captive's investment income up to $1.2 million in annual premiums. Captive insurance companies can retain profits for businesses and provide coverage otherwise unavailable if structured properly with legal and tax advisors.
