Introduction: What is Captive Insurance and Why It Matters
Captive insurance is a formalized self-insurance strategy where a business creates its own insurance company to insure its risks. Unlike traditional insurance, where premiums are paid to third-party carriers, a captive insurance company is wholly owned and controlled by its parent organization(s). This arrangement allows businesses to customize coverage, potentially reduce costs, access reinsurance markets directly, and capture underwriting profits that would otherwise go to commercial insurers. With over 7,000 captives globally managing more than $140 billion in premium volume, captive insurance has become a mainstream risk management tool for organizations seeking greater control over their insurance programs and costs.
Core Captive Insurance Concepts
Key Terminology
- Captive: A licensed insurance company owned by its insured(s)
- Parent: The organization(s) that owns the captive
- Domicile: The jurisdiction where the captive is licensed and regulated
- Fronting Carrier: Commercial insurer that issues policies backed by captive
- Cell Captive: Structure allowing multiple participants to share administrative costs while maintaining separate underwriting accounts
- Reinsurance: Insurance for insurance companies, often accessed by captives
- Premium: Payments made to the captive to cover expected losses
- Surplus: Accumulated assets exceeding liabilities within a captive
- Feasibility Study: Analysis determining if a captive makes financial sense
- Actuarial Analysis: Statistical evaluation of potential losses and appropriate premium levels
Captive vs. Traditional Insurance Comparison
| Aspect | Traditional Insurance | Captive Insurance |
|---|---|---|
| Ownership | Third-party carrier | Parent company/insured |
| Control | Limited policyholder input | High control over coverage, claims, investments |
| Premium Determination | Industry pools, carrier profit needs | Based on parent’s actual loss experience |
| Coverage Availability | Standard policies, market-dependent | Customized to specific needs |
| Profit & Investment | Benefits carrier shareholders | Returns to parent/owners |
| Tax Treatment | Premiums are tax-deductible business expenses | May be tax-deductible if properly structured |
| Regulatory Requirements | Highly regulated | Regulated, but often less stringently |
| Risk Pool | Shared across many unrelated insureds | Limited to parent and affiliates (pure captive) |
| Capital Requirements | Borne by carrier | Parent must provide initial and ongoing capital |

Key Financial and Tax Considerations
Financial Benefits
- Premium Cost Control: Typically 10-25% savings vs. commercial insurance
- Cash Flow Improvement: Funds remain within captive until claims paid
- Direct Access to Reinsurance: May reduce costs by 5-15% in applicable scenarios
- Investment Income: Captive retains investment returns on reserves
- Underwriting Profit Capture: Typically 5-15% of premium in well-managed programs
- Customized Coverage: Tailored to specific risks, often providing broader protection
- Claims Management Control: Potential 10-20% reduction in claims costs through active management
Tax Considerations
Premium Deductibility: Generally deductible as business expense if “insurance” for tax purposes
Insurance Requirements for Tax Purposes:
- Risk transfer must exist
- Risk distribution must be present
- Arrangement must constitute “insurance” in commonly accepted sense
- Premiums must be reasonable and arm’s length
831(b) “Micro-Captive” Election:
- Captives with up to $2.3M annual premiums (2023, adjusted annually for inflation)
- Taxed only on investment income, not underwriting profit
- Subject to IRS scrutiny; requires careful implementation
Transfer Pricing Considerations:
- Premiums must be justifiable via actuarial analysis
- Documentation of arm’s length pricing essential
- Potential exposure to controlled foreign corporation (CFC) rules
Risk Distribution Requirements
- Safe Harbor Guidelines:
- 12+ unrelated insureds, none with >15% of total risk
- 7+ unrelated insureds, none with >35% of total risk
- 5+ unrelated insureds, none with >50% of total risk
- Brother-sister entities may provide distribution if properly structured
