What Are the Refund Rules for Level-Funded Health Plans in 2026?

Level-funded health plans have become one of the fastest-growing coverage models for small and mid-sized employers, but the refund rules attached to them remain one of the most misunderstood parts of the arrangement. If you sponsor a level-funded plan, the single most important thing to understand is this: any surplus in your claims fund at the end of the policy year is potentially refundable to you, but only under specific conditions, and only after the carrier completes a runout and reconciliation process that can take months. Refunds are not guaranteed, they are not automatic, and in many cases they are smaller than employers expect once stop-loss recovery, fees, and state-specific rules are factored in.

A level-funded plan combines a fully insured monthly premium with the mechanics of self-funding. Each month, the employer pays a fixed amount that is divided into three buckets: a claims fund (typically 70 to 80 percent of the premium), stop-loss insurance premiums (roughly 15 to 20 percent), and administrative fees (about 5 to 10 percent). If the group's actual claims come in below the amount sitting in the claims fund at the end of the plan year, the carrier may return the surplus to the employer as a refund.

The refund rules hinge on the policy's specific language. Most level-funded contracts state that surplus funds are returned after the claim runout period, which is usually 90 days but can extend to 12 months for certain large or late-reported claims. This means an employer whose plan year ends December 31 typically does not see a refund until the second or third quarter of the following year. Some carriers apply the surplus as a credit against next year's premiums rather than issuing a check, which is a detail employers should clarify before signing. Others retain a portion of the surplus to seed the next year's claims fund, particularly for groups with volatile claims history.

It is also worth being skeptical of how refunds are marketed. Carriers frequently advertise refund potential of 5 to 15 percent of annual premium, but actual refund rates across the market have historically averaged closer to 3 to 8 percent, and in high-claims years many groups receive nothing at all. The refund is a possibility, not a promise, and any sales pitch that treats it as a certainty deserves scrutiny.

Why Refunds Exist and How the Money Flows

The reason refunds exist at all is regulatory arbitrage combined with risk transfer. Level-funded plans are technically self-funded plans governed by ERISA (for most private employers), but they are paired with fully insured stop-loss coverage. Because the employer's monthly payment is fixed, the arrangement looks like traditional insurance from a cash-flow perspective. The claims fund, however, behaves like the employer's own money. If employees generate fewer claims than projected, the unspent portion of that fund belongs, in most contracts, back to the employer.

The money flow works like this: each monthly payment deposits funds into the claims account. As employees incur medical, pharmacy, and other covered claims, the carrier or third-party administrator draws from that account to pay providers. Stop-loss insurance sits above the fund and reimburses the claims fund once individual claims exceed the specific deductible (commonly set between $15,000 and $50,000 per employee per condition) or once aggregate claims exceed the aggregate attachment point (usually set at 110 to 125 percent of expected claims). Stop-loss recoveries replenish the fund, which is why stop-loss terms directly affect refund size. A poorly negotiated aggregate attachment point can quietly absorb what would otherwise be a refund.

At the end of the year, the carrier performs a reconciliation: total claims paid plus projected runout claims are compared against the total funded. If claims plus required reserves fall short of the funded amount, the difference is the surplus. Carriers may hold back a reserve for pending claims, sometimes 5 to 10 percent of the fund, until the runout period closes, then release the remainder.

Practical Steps to Protect and Maximize Your Refund Position

Employers who want to position themselves for the best possible refund outcome should treat the contract negotiation phase as the moment that matters most. First, scrutinize the refund clause itself. Ask whether surplus is paid as cash, applied as a premium credit, or rolled into next year's fund, and insist on a defined timeline for release after runout. Second, negotiate the aggregate stop-loss attachment point. A lower attachment point (closer to 110 percent of expected claims) means stop-loss kicks in sooner, protecting the fund and preserving refund potential in a moderately bad year.

Third, review the specific stop-loss deductible. Setting it too high saves premium but exposes the claims fund to large individual claims that can wipe out any surplus. Fourth, ask about reserve holdbacks and interest. Some contracts allow the carrier to earn interest on held reserves without sharing it; pushing for interest crediting is a reasonable ask. Fifth, request monthly claims utilization reports and reconcile them against your own records. Errors in claims adjudication happen, and an unappealed erroneous claim directly reduces your refund. Finally, document everything in writing before renewal, because refund disputes almost always come down to what the contract says versus what the broker or carrier representative said in a meeting.

Level-Funded vs. Fully Insured vs. Self-Funded: Where the Money Goes

Understanding refund rules requires seeing how level funding compares to the alternatives, because the refund mechanism is precisely what distinguishes it from traditional insurance.

The table makes the trade-off clear: fully insured plans offer zero refund potential but zero downside; pure self-funding offers full upside but requires the balance sheet to absorb bad claim years; level funding sits in between, capping downside through stop-loss while returning some upside. For groups under 50 employees, level funding is often the only practical way to access self-funding economics, which is why carriers have pushed these products hard since the ACA's small-group rules took effect.

Common Mistakes Employers Make With Refund Expectations

The most frequent mistake is budgeting around a refund that never materializes. Some employers count projected refunds as a line item in next year's benefits budget, then face a shortfall when claims run hot. Refunds should be treated as a windfall, not a plan. The second mistake is ignoring the runout period. Employers sometimes demand their refund immediately after the plan year ends, not realizing that late-arriving claims, particularly from out-of-network providers or stop-loss recoveries, can take 6 to 12 months to fully settle. Demanding early release can backfire if the carrier later discovers the fund was overdrawn.

A third mistake is failing to understand state-specific rules. While ERISA preempts most state insurance regulation for self-funded arrangements, the stop-loss component is insured and regulated at the state level. Some states impose filing requirements, minimum attachment points, or restrictions on how stop-loss products are sold to small groups, and these can indirectly affect refund mechanics. Fourth, employers often overlook the tax treatment. Refund checks are generally not taxable income if they represent a return of the employer's own premium payments, but if the plan was funded partly with pre-tax employee contributions, the refund allocation can get complicated. A conversation with a tax advisor before year-end is cheap insurance. Finally, many employers never audit the claims data underlying the reconciliation, accepting the carrier's numbers at face value. Industry analyses, including pieces in BenefitsPRO, have flagged that silent risks in level-funded contracts, such as undisclosed reserve holdbacks or unfavorable reconciliation formulas, cost employers real money every year.

When to Act: Timing Rules and Key Dates

The refund timeline follows the plan year, not the calendar. If your plan year ends December 31, the reconciliation process typically begins in January, with preliminary surplus calculations available by February or March. The formal runout period then runs 90 days to 12 months depending on the contract, and final refund release usually occurs between April and September of the following year. Employers should calendar a reconciliation review meeting for roughly 60 to 90 days after plan year end, and a second checkpoint at runout close.

Renewal timing matters just as much. Most level-funded contracts lock in terms 60 to 90 days before renewal, which means the negotiation window for refund clauses, attachment points, and reserve terms closes well before the current year's refund is even known. If you are unhappy with how your current refund was handled, the time to fix it is during the next renewal negotiation, not after. Employers considering a switch to level funding should also note that the first year is often the best refund year, because carriers price conservatively for unknown groups. Renewal years typically see tighter funding based on actual claims, shrinking the refund cushion. This is not a reason to avoid level funding, but it is a reason not to build a multi-year budget on year-one refund performance.

Cost, Pricing, and What Refunds Mean for Your Bottom Line

Level-funded premiums typically run 10 to 30 percent below comparable fully insured premiums for healthy groups, partly because they avoid certain state mandates and premium taxes under ERISA preemption. For a 25-employee group paying $8,000 per employee per year in fully insured premiums ($200,000 total), a level-funded alternative might cost $170,000 to $185,000. A mid-range refund of 5 percent on that premium would return roughly $8,500 to $9,250, meaningful money for a small business but not transformative. In a bad claims year, the aggregate stop-loss protection caps exposure at the attachment point, so the employer's worst case is paying the full level premium with no refund, not an open-ended liability.

Employers should also price the administrative layer. TPA fees, PEPM (per-employee-per-month) charges, network access fees, and stop-loss premiums all come out of the fixed payment before any refund math begins. Comparing two level-funded quotes requires looking past the headline monthly cost to the total funding structure, because a cheaper quote with a higher aggregate attachment point can produce worse net outcomes. The honest framing: level funding is a cash-flow tool with a modest refund kicker, not an investment strategy.

The Bottom Line for Employers in 2026

Level-funded refund rules reward employers who read the contract and punish those who rely on sales presentations. The refund mechanism is real, it is regulated primarily through the contract terms and the insured stop-loss component, and it can return meaningful money when claims run cool. But the average refund across the market is modest, the timeline is slow, and the terms vary enough between carriers that two identical groups can have very different experiences. With health insurance costs projected to keep climbing through 2026, level funding remains a legitimate steppingstone toward full self-funding for growing employers, and the refund clause is one of the few genuinely negotiable elements in the arrangement. Negotiate it deliberately, monitor claims monthly, and treat every refund as a bonus rather than a budget line.
