What is group health insurance?
Group health insurance is health coverage provided by an employer to its employees and often their dependents. Unlike individual health insurance, which a person purchases on their own, group plans spread risk across many people—typically resulting in lower premiums and better coverage.
How does group health insurance work?
The employer selects a health plan (or plans) to offer and typically pays a portion of the premium—often 50% or more. Employees then decide whether to enroll and pay their share of the premium through payroll deductions. Many employers pay 50-80% of employee-only premiums, with employees paying the rest. Dependent coverage may require employees to pay a larger share.
What are the participation requirements for group plans?
Most insurers require a minimum percentage of eligible employees to enroll—typically 70%—to prevent only high-cost employees from signing up (a problem called adverse selection). Employees who have coverage elsewhere, such as through a spouse, usually count toward participation without enrolling.
Why do employers offer group health insurance?
Offering health insurance helps employers attract and retain talented workers in a competitive job market. Employer contributions are generally tax-deductible, and employees with access to preventive care tend to be healthier and more productive. Employers with 50 or more employees are also required to offer coverage under the ACA.
What are the benefits of group health insurance for employees?
Employees typically pay lower premiums than individual coverage because the employer pays a share. Premiums are deducted pre-tax through payroll, reducing taxable income. Employees get guaranteed coverage regardless of pre-existing conditions, comprehensive benefits including medical (often dental and vision), and the ability to cover spouses and children.
What is an HMO plan?
HMO (Health Maintenance Organization) plans require the use of in-network providers. A primary care physician (PCP) coordinates care, and referrals are typically needed to see specialists. HMOs generally have the lowest premiums but offer the least flexibility. They're best for employees who don't mind coordinating care through a PCP and want lower costs.
What is a PPO plan?
PPO (Preferred Provider Organization) plans allow employees to see any provider, in-network or out-of-network. Costs are lower when using in-network providers. No referrals are needed for specialists. PPOs have higher premiums than HMOs but offer more flexibility. They're best for employees who want the flexibility to see specialists or out-of-network providers.
What is an EPO plan?
EPO (Exclusive Provider Organization) plans require using in-network providers except for emergencies, but don't require referrals for specialists. They're a hybrid between HMO and PPO plans. EPOs are best for employees who want flexibility without referrals but are comfortable staying in-network.
What is a POS plan?
POS (Point of Service) plans combine features of HMO and PPO plans. A primary care physician coordinates care, but out-of-network care is covered at a higher cost. They're best for employees who want coordinated care with some flexibility for out-of-network care.
What is a high-deductible health plan (HDHP)?
HDHPs have lower monthly premiums but higher annual deductibles. Employees pay more out-of-pocket until the deductible is met. HDHPs can be paired with a Health Savings Account (HSA) for tax-advantaged savings. They're best for generally healthy employees who want lower premiums and can afford higher out-of-pocket costs.
2026 HDHP and HSA Limits:
Limit Type | Individual | Family |
HDHP Minimum Deductible | $1,700 | $3,400 |
HDHP Out-of-Pocket Maximum | $8,500 | $17,000 |
HSA Contribution Limit | $4,400 | $8,750 |
HSA Catch-Up Contribution (Age 55+) | +$1,000 | +$1,000 |
What is a fully-insured health plan?
With a fully-insured plan, the employer pays a fixed premium to an insurance company, which assumes all risk for claims. The insurer handles claims processing, provider networks, and compliance. Premiums are based on the number of employees, demographics, and location. This is the most common option for small to mid-size businesses and offers predictable costs.
What is a self-funded (self-insured) health plan?
With a self-funded plan, the employer pays claims directly instead of purchasing insurance. Stop-loss insurance is often used to protect against catastrophic claims. This approach offers flexibility in plan design and potential cost savings but requires careful financial management. Self-funding is typically used by larger employers (100+ employees) who can absorb claim variability.
What is a level-funded health plan?
Level-funded plans are a hybrid approach combining elements of both fully-insured and self-funded plans. Employers pay a fixed monthly amount that covers expected claims, administrative costs, and stop-loss insurance. Unused claim funds may be refunded to the employer. This is a good option for smaller companies (10-100 employees) who want predictable costs with some self-funding benefits.
Which employers are required to offer health insurance under the ACA?
The ACA's employer mandate applies to Applicable Large Employers (ALEs)—businesses with 50 or more full-time equivalent employees. Small employers with fewer than 50 FTEs are not required to offer health insurance, but may choose to do so.
What are the ACA coverage requirements for large employers?
Applicable Large Employers must offer coverage to at least 95% of full-time employees (those working 30+ hours per week) and their dependents under age 26. Coverage must be "affordable" and provide "minimum value" (meaning the plan pays at least 60% of covered health care costs).
What does "affordable" coverage mean under the ACA in 2026?
In 2026, coverage is considered affordable if the employee's premium for self-only coverage does not exceed 9.02% of household income (up from 9.02% in 2025). To meet the Federal Poverty Line affordability safe harbor, the employee cost for self-only coverage must not exceed $129.89 per month.
What are the ACA penalties for non-compliance in 2026?
There are two potential penalties. Penalty A applies if an employer doesn't offer coverage: $3,340 per full-time employee annually ($278.33/month), minus the first 30 employees, if any employee receives marketplace subsidies. Penalty B applies if coverage is offered but is unaffordable or inadequate: $5,010 per employee annually ($417.50/month) for employees who receive marketplace subsidies. The IRS actively enforces the employer mandate.
Who counts as a full-time employee under the ACA?
Full-time employees are those working 30 or more hours per week. Part-time employee hours are counted toward full-time equivalents (FTEs) when determining whether an employer is an Applicable Large Employer. For example, two employees working 15 hours per week each equal one FTE.
What do ACA-compliant group health plans cover?
ACA-compliant group health plans must cover essential health benefits, including preventive care (at no cost when using in-network providers), hospitalization and emergency services, prescription drugs, mental health and substance use treatment, maternity and newborn care, pediatric services (including dental and vision for children), laboratory services, and rehabilitative services.
Can group plans deny coverage for pre-existing conditions?
No. Under the ACA, group health plans cannot deny coverage or charge higher premiums based on pre-existing conditions. This applies to all ACA-compliant group plans regardless of employer size.
Do group plans include dental and vision coverage?
Many employers offer dental, vision, and life insurance in addition to medical coverage—either bundled with the health plan or as separate coverage options. Pediatric dental and vision are required as essential health benefits, but adult dental and vision are optional.
What is an ICHRA?
ICHRA (Individual Coverage Health Reimbursement Arrangement) is a modern alternative to traditional group health insurance. Available since January 2020, ICHRAs allow employers of any size to reimburse employees tax-free for individual health insurance premiums and qualified medical expenses.
How does ICHRA work?
The employer sets a monthly allowance for employees. Employees purchase their own individual health insurance, submit proof of coverage and expenses, and receive tax-free reimbursement from the employer up to the set allowance. Employees choose their own plan from any carrier with any network.
What are the benefits of ICHRA for employers?
ICHRA offers predictable costs with no surprise premium increases. There are no minimum or maximum contribution requirements. Employers can offer different allowances to different employee classes (full-time, part-time, remote workers, and employees in different locations). Reimbursements are tax-deductible. Unlike group plans, there are no participation requirements. ICHRA can satisfy the ACA employer mandate requirements when affordable coverage is offered.
What are the benefits of ICHRA for employees?
Employees choose their own health plan from any carrier with any network. Coverage is portable—employees keep their plan if they leave the company. Reimbursements are tax-free. Employees can pick coverage that fits their specific needs, including preferred doctors, specialists, and family situation.
How does ICHRA affect ACA marketplace subsidies?
Employees offered an affordable ICHRA may not be eligible for ACA marketplace premium tax credits. In 2026, an ICHRA is considered affordable if the employee's cost for the lowest-cost silver plan (after the employer contribution) doesn't exceed 9.02% of household income. Employees should compare the ICHRA offer to potential subsidies when making decisions.
Can employers offer both a group plan and an ICHRA?
Yes. Employers can offer ICHRA alongside a group plan to different employee classes. For example, an employer might offer a traditional group plan for full-time employees and an ICHRA for part-time or remote workers.
How fast is ICHRA adoption growing?
ICHRA adoption has increased by more than 1,000% since 2020. In 2025, large-employer ICHRA adoption grew 34% year-over-year, while small-employer adoption grew 52%. Forecasts suggest ICHRA adoption could reach 5.8 million covered lives by 2026 and up to 15 million by 2032. HRA Council members report 400-800% increases in employer quote requests for 2026 and 2027.
Are small businesses required to offer health insurance?
No. Small businesses with fewer than 50 full-time equivalent employees are not required to offer health insurance under the ACA. However, offering coverage can help attract and retain employees in a competitive job market.
What health insurance options do small businesses have?
Small businesses can purchase a traditional fully-insured or level-funded group plan, use the SHOP Marketplace, offer an ICHRA, or offer a QSEHRA. Each option has different advantages depending on the business's size, budget, and goals.
What is the SHOP Marketplace?
The Small Business Health Options Program (SHOP) allows small employers to shop for group coverage. SHOP is generally the only way to qualify for the Small Business Health Care Tax Credit, which provides up to 50% of employer contributions for qualifying small employers with fewer than 25 employees and average wages under $50,000.
What is a QSEHRA?
QSEHRA (Qualified Small Employer HRA) is available only to small employers (fewer than 50 employees) who don't offer a group plan. Like ICHRA, it allows employers to reimburse employees for individual coverage, but it has annual contribution limits and must be offered to all eligible employees equally. QSEHRA is a simpler option for very small employers.
How are small group plan premiums determined?
Small group plans (1-50 employees in most states) are community-rated, meaning premiums cannot vary based on health status. However, they can vary by age, location, tobacco use, and family size.
Can part-time employees get group health coverage?
It depends on the employer's policy. Under the ACA, only full-time employees (30+ hours per week) must be offered coverage by large employers. However, employers may choose to extend coverage to part-time workers. With an ICHRA, employers can set different allowances for different employee classes, including part-time workers.
Can 1099 contractors get group health coverage?
No. Independent contractors (1099 workers) are not employees and cannot be included in a traditional group health plan. Contractors must obtain their own individual coverage. However, some employers offer informal benefits to contractors, such as higher pay to offset health insurance costs, to help with retention and recruitment.
What is the difference between group health insurance and individual insurance?
Group insurance is provided through an employer, with the employer typically paying part of the premium. Individual insurance is purchased by individuals directly through the marketplace or from insurers. Group plans often have lower premiums due to risk pooling across many employees, and premiums are paid pre-tax through payroll deductions.
What is HIPAA compliance for group health plans?
The Health Insurance Portability and Accountability Act (HIPAA) requires group health plans to protect employees' health information. It also limits exclusions for pre-existing conditions and guarantees coverage renewal. Employers and their plan administrators must maintain the confidentiality of employee health data.
What is COBRA, and who does it apply to?
COBRA (Consolidated Omnibus Budget Reconciliation Act) requires employers with 20 or more employees to offer continuation of group health coverage to employees and dependents who would otherwise lose coverage due to certain qualifying events, such as termination or reduction in hours. Employees typically pay the full premium plus a 2% administrative fee.
How should startups approach health insurance?
Startups have several options: traditional small-group plans, level-funded plans for greater control, or ICHRAs for maximum flexibility and predictable budgeting. Many startups choose ICHRAs because they can start with any budget, scale as the company grows, and avoid the complexity of managing a group plan. Consulting with a licensed insurance agent helps evaluate the specific situation.
Will 2026 be 'the year of ICHRA'?
Industry experts believe ICHRA is at an inflection point. With adoption up more than 1,000% since 2020 and employer quote requests up 400-800% for 2026-2027, ICHRAs are becoming mainstream. While not yet mass-adopted by the largest employers, mid-sized businesses (50-500 employees) are driving much of the growth. The combination of cost control, employee choice, and budget predictability makes ICHRA increasingly attractive as traditional group insurance costs continue to rise. Notably, 83% of new ICHRA adopters had not previously offered health coverage.
