Short answer: Employers self-fund to gain control: access to their own claims data, ERISA preemption of state mandates and premium taxes, cash-flow advantages, the ability to keep savings in a good year, and freedom to customize the plan and its cost-containment strategies. The trade-off is taking on claims risk.
The core motivation is control. A self-funded employer can see its own claims data (to target cost drivers), avoid many state-mandated benefits and state premium taxes through ERISA preemption, improve cash flow (paying claims as they occur rather than premiums up front), keep the savings when claims run low, and design the plan and vendor stack it wants.
The obvious downside is risk, but stop-loss insurance caps it, and level-funded designs package the whole thing to behave like a fully insured plan. Self-funding tends to fit employers with stable, reasonably healthy workforces and the appetite to manage the plan actively; it’s less suited to very small or highly risk-averse groups without a level-funded wrapper.
