Home / Health / Group Health Insurance For Employers
Employer group health insurance is a health plan purchased by a business to cover its employees and, often, their dependents. Because coverage is pooled across all enrolled employees, group plans typically offer lower premiums than individual health insurance, making them one of the most affordable ways for American workers to access comprehensive health coverage.
According to the KFF 2025 Employer Health Benefits Survey, the average annual premium for employer-sponsored health insurance is $9,325 for single coverage and $26,993 for family coverage. On average, employers cover 84% of the single-coverage premium, meaning employees contribute approximately $1,492 per year out of pocket.
Under the Affordable Care Act (ACA), businesses with 50 or more full-time equivalent (FTE) employees must offer affordable health coverage to full-time staff. Businesses with fewer than 50 FTEs are not required to offer coverage under federal law, but many do so to attract and retain talent.
| Coverage Type | Avg. Annual Premium | Employer Pays (Avg.) | Employee Pays (Avg.) |
|---|---|---|---|
| Single Coverage | $9,000 – $9,700 / year | 84% ($7,500 – $8,200) | 16% ($1,400 – $1,600) |
| Family Coverage | $26,000 – $27,500 / year | 74% ($19,000 – $20,000) | 26% ($6,800 – $7,200) |
| Small Business Single (10–199 employees) | $8,900 – $9,700 / year | Varies — 29% cover full premium | 14–18% of premium |
| Plan Type | How It Works | Best For | Cost vs. HMO |
|---|---|---|---|
| HMO | Employees choose a primary care physician (PCP) and need referrals for specialists. Must stay in-network. | Budget-conscious employers; local workforces | Lowest premium option |
| PPO | No referrals needed. Employees can see any in-network or out-of-network doctor. | Employers wanting to offer flexibility and broad national networks | 15–30% higher premium than HMO |
| HDHP + HSA | Lower monthly premiums with a higher deductible. Paired with a tax-advantaged Health Savings Account (HSA). | Healthy employees; cost-conscious employers wanting to reduce premium spend | Lower premium; higher employee out-of-pocket costs |
| EPO | Similar to PPO but no out-of-network coverage except emergencies. | Employers in areas with strong local networks | Lower premium than PPO |
| POS | Hybrid of HMO and PPO, requires a PCP but allows some out-of-network visits at higher cost. | Employers wanting a middle-ground flexibility option | Similar to PPO |
| Tax Benefit | Who Qualifies | Key Details |
|---|---|---|
| Employer Premium Deduction | All businesses that pay employee premiums | Employer-paid premiums are fully tax-deductible as an ordinary business expense under IRS rules. |
| ACA Small Business Tax Credit | Businesses with fewer than 25 FTE employees, average wage below $56,000 (2025) | Up to 50% credit on premiums paid if purchased through the SHOP Marketplace. Claim via IRS Form 8941. |
| QSEHRA Reimbursement | Businesses with fewer than 50 FTE employees (no existing group plan) | Reimburse employees tax-free up to $6,350/year (single) or $12,800/year (family) in 2025 for individual premiums and medical expenses. |
| Section 125 Cafeteria Plan | All businesses | Allows employees to pay premiums with pre-tax dollars, reducing taxable payroll and income. |
Employer group health insurance is a health plan purchased by a business to cover its employees. Coverage is pooled across all enrolled employees, which lowers per-person costs compared to individual health plans. Employers typically pay a portion of the monthly premium and employees pay the rest through payroll deductions.
According to the KFF 2025 Employer Health Benefits Survey, the average annual premium is $9,325 for single coverage and $26,993 for family coverage. Employers pay approximately 84% of single-coverage premiums on average, with employees contributing around $1,492 per year for their own coverage.
Under the ACA, employers with 50 or more full-time equivalent (FTE) employees, known as Applicable Large Employers (ALEs), are required to offer affordable minimum essential health coverage to full-time employees. Businesses with fewer than 50 FTEs are not federally required to offer coverage but may choose to do so.
Most insurers and states require employers to contribute at least 50% of the employee-only (single coverage) monthly premium. Employers are not required by federal law to contribute to the cost of dependent or family coverage, though many choose to offer a partial contribution.
The main types are HMOs (Health Maintenance Organizations), PPOs (Preferred Provider Organizations), HDHPs (High-Deductible Health Plans, often paired with HSAs), EPOs (Exclusive Provider Organizations), and POS (Point of Service) plans. Each type offers a different balance of premium cost, network flexibility, and out-of-pocket expenses.
