The 2026 Employer Health Benefits Survey found small business employees took the biggest hit. Workers at companies with 10 to 99 employees typically shoulder a larger share of their insurance costs than people at bigger firms.

Employers report that workers now pay an average of $7,471 a year toward premiums for family coverage. That is up roughly 9%, or $621, from last year. Almost 157 million Americans under retirement age rely on employer-sponsored coverage.

"Workers are paying a bigger chunk this year," said Matthew Rae, associate director of KFF's Program on the Health Care Marketplace, "which also brings up the issue of affordability." The survey indicates many people see their expenses climb without clear improvements in benefits. Small businesses, which employ roughly 62.3 million people, could feel the impact more acutely.

Healthcare costs have become a midterm election issue. An AP-NORC poll in October found about 7 in 10 registered voters call healthcare "one of the most important issues" in this election. President Donald Trump has pitched his most-favored nation prescription drug pricing as a way to cut costs.
