2026 Group Health Insurance Renewal: What Employers Need to Do Before Open Enrollment

If your group health plan renews on a calendar-year cycle, your renewal packet is either already in your inbox or about to be. This year, more than most, is not the year to rubber-stamp it.

Why This Renewal Cycle Is Different

Multiple independent estimates point to one of the steepest premium jumps small employers have seen in over a decade:

  • Mercer projects employer health costs rising roughly 6.5% in 2026
  • Aon puts the number closer to 9.5%
  • WTW’s employer survey lands in a similar range
  • Rate filings tracked by KFF show insurers requesting a median 14% increase for the small group market specifically, with some state filings averaging 13.6%

Whichever estimate proves closest, the direction is the same: costs are climbing faster than wage growth, and employers who treat renewal as a formality this year are likely to overpay.

The Renewal Timeline Employers Should Follow

90–120 days before renewal: Request your renewal illustration early and start gathering utilization data. If your broker can’t produce claims trend data or a year-over-year comparison, that’s a warning sign about how much shopping actually happened on your behalf.

60–90 days before renewal: This is the window to request competing quotes — including level-funded or self-funded alternatives if your group size qualifies (typically 10+ employees). A broker who only brings back one renewal number from your existing carrier isn’t doing a market check.

30–60 days before renewal: Compare plan designs, not just premiums. A lower headline number paired with a higher deductible or a narrower network can cost your employees — and your HR team’s time fielding complaints — more than it saves.

Inside 30 days: Finalize enrollment materials, update payroll deductions, and communicate changes to employees. Waiting this long to start shopping means you’ve lost your leverage.

What to Actually Ask Your Broker This Cycle

  1. “What did you shop this renewal against?” — Not just “did you shop it,” but which carriers, which plan types, and what came back.
  2. “Does level-funding make sense for us this year?” — With traditional premiums rising double digits in some markets, level-funded and self-funded options are pulling more mid-size groups (10–200 employees) than in past cycles.
  3. “What’s driving our specific increase?” — Claims experience, network changes, and rating-area shifts all move the number differently. A generic “the market’s up” answer isn’t good enough.
  4. “What happens if we do nothing?” — Passive renewal (auto-accepting the illustration) is common, and carriers know it. Ask directly what you’re leaving on the table by not shopping.

When It’s Time to Switch Brokers

If your renewal packet arrived with no market comparison, no plan design alternatives, and no explanation of your specific rate drivers, your current broker may not be actively marketing your account — even if they’re a perfectly nice person to work with.

This is exactly the situation where finding a broker who specializes in your industry, group size, and region pays off. On GroupHealthMatch, you can filter for brokers by specialty — level-funded plans, self-funded, specific industries — and see verified profiles before you make a call.

The Bottom Line

A 6–14% increase compounding year over year is not a rounding error — for a 50-employee group, it can mean tens of thousands of dollars in avoidable cost. The employers who come out ahead this renewal season are the ones who start the process early and ask harder questions of their broker, not the ones who wait for the packet to arrive and sign it.
