A median health insurance increase of 11 percent is hitting small businesses for 2026 — on top of rising commercial property, auto, and liability costs. For operations already running on thin margins, the compounding effect is becoming a question of survival.
11% – Median health premium increase for small group plans (KFF/Peterson, 318 insurers)
32% – Highest proposed increase among ACA small group insurers for 2026
10–15% -Typical commercial auto premium increase for most small fleets in 2026
An analysis by the Peterson-KFF Health System Tracker, drawing on rate filings from 318 insurers across all 50 states and D.C., found that small businesses with ACA-compliant health plans face a median premium increase of 11 percent for 2026. About 10 percent of those insurers proposed increases of 20 percent or more. Only three requested rate decreases. The figures are preliminary — final rates are expected in late summer — but the direction is clear, and the scale is significant for businesses that lack the negotiating leverage of large employers.
What Is Driving the Increases
Insurers filing rate increases for 2026 cited a consistent set of pressures in their documentation. The primary driver is underlying healthcare cost growth, which insurers estimate at approximately 9 percent for the coming year. Hospital care, physician services, and prescription drug costs are all rising, and providers are commanding higher reimbursement rates in part because of labor shortages and because of consolidation that has reduced market competition in many regions.
GLP-1 medications — the class that includes widely prescribed weight-loss and diabetes drugs — emerged as a notable secondary driver. KFF found that 27 of the 96 insurer filings reviewed in detail specifically cited GLP-1 costs as a factor in their proposed increases. Some insurers responded by excluding coverage of GLP-1 medications for weight-loss purposes from their 2026 small group plans. A further complicating factor is the enrollment trajectory of the small group market itself: as healthier employee groups migrate to self-funded arrangements or individual market options, the remaining ACA small group risk pool becomes disproportionately higher-cost, driving premiums upward for those who stay.
Health Is Only Part of the Picture
Health insurance is the most visible pressure, but it is not the only one. SmartFinancial’s January 2026 review of commercial insurance found that overall commercial insurance rates rose approximately 3 percent in the first half of 2025, with significant variation by line. Commercial auto remained one of the most pressured segments, with many businesses seeing renewal increases in the 10 to 15 percent range — and higher for operations with recent at-fault claims or heavy commercial fleets. Rising repair costs, parts shortages, and higher vehicle replacement values — particularly for vehicles equipped with advanced driver assistance systems — are sustaining claims severity even as frequency stabilises.
| Coverage Line | 2026 Trend | Primary Driver |
|---|---|---|
| Small group health (ACA) | +11% median; up to +32% | Healthcare cost growth (~9%); GLP-1 drugs; declining enrollment |
| Commercial auto | +10–15% typical | Repair costs; parts prices; labour; ADAS vehicle technology |
| Commercial property | Mixed; selective in CAT zones | Climate exposure; reinsurance cost; reconstruction inflation |
| General liability / umbrella | Firm; selective on large limits | Social inflation; rising litigation severity; nuclear verdicts |
| Workers’ compensation | Relatively stable; some reductions | More stable than other lines; clean-claims businesses seeing flat renewals |
| Cyber liability | Flat to modest decrease for strong controls | Improved risk management offsetting threat growth |
The Compounding Effect on Small Business
Large employers absorb insurance cost increases through scale, self-funding, and negotiating leverage. Small businesses have none of those tools. A business with 15 employees offering ACA-compliant coverage facing an 11 percent premium increase on a plan costing $27,000 per family per year absorbs that cost in full — or reduces coverage, reduces staff, or raises prices. When that increase arrives simultaneously with commercial auto, property, and liability renewals also rising, the compounding effect becomes a material threat to operations.
What Small Businesses Are Doing
- Shopping coverage at renewal rather than auto-renewing — comparing quotes across multiple carriers on all lines simultaneously
- Exploring ICHRA arrangements that allow defined contribution amounts while employees select individual market plans, decoupling premium volatility from the employer’s direct exposure
- Implementing documented risk controls across property, auto, and liability to qualify for better underwriting terms — carriers are increasingly rewarding evidence-based submissions
- Raising deductibles on commercial lines where cash reserves allow, to reduce premium outlay in exchange for increased self-insured exposure
- Reviewing whether GLP-1 exclusion plans offer meaningful premium relief given employee demographics, and what the recruitment and retention implications are of offering reduced benefits
The broader trajectory does not suggest immediate relief. Deloitte’s 2026 global insurance outlook notes that tariff-driven cost increases in imported materials — relevant to commercial property and auto claims — are adding further complexity to insurer cost modelling. Commercial property insurers in catastrophe-exposed markets are tightening terms alongside prices. For small businesses located in wildfire corridors, hurricane zones, or flood plains, coverage availability itself — not just cost — is increasingly at issue.
