Group health insurance explained

Health benefits built around your business.

A group plan can help protect employees, strengthen recruiting and turn part of your compensation budget into a valuable benefit. The right time depends on your workforce, budget and business goals.

What is group health insurance?

Group health insurance is coverage sponsored by an employer or organization for eligible employees and, when offered, their dependents. The employer selects the plan or menu of plans, determines eligibility and usually contributes toward the cost.

Business size matters: Small employers generally have 1–50 employees for SHOP eligibility, although state rules can vary. Employers averaging at least 50 full-time employees, including full-time-equivalent employees, during the prior year are generally Applicable Large Employers and may be subject to federal employer-coverage requirements.
Solo ownerUsually individual coverage

A business with no common-law employee other than an owner or spouse generally does not qualify for SHOP group coverage.

1–50 employeesSmall-group options

Group insurance, SHOP coverage, or an employer-funded individual-coverage arrangement may be available.

50+ FTEsAdditional ACA duties

Affordability, minimum-value, reporting and employer shared-responsibility rules may apply.

When should an employer consider a group plan?

The best time is when the benefit supports the people strategy and the business can maintain its share of the cost—not only during a hiring emergency.

Do not wait until renewal week. Begin reviewing options roughly 60–90 days before your desired effective date so there is time to collect census data, compare networks, explain employee costs and complete enrollment.
Employees are asking for health benefits

Repeated requests, low participation in individual coverage or concerns about family benefits are strong signals.

Recruiting and retention are becoming harder

A meaningful benefit can strengthen the total compensation package and reduce the gap with competing employers.

The workforce has reached a stable size

The company can satisfy carrier eligibility and participation rules and expects to retain enough enrolled employees.

The budget can handle renewals

The employer can contribute consistently and has modeled employee growth and potential annual rate changes.

The company is approaching 50 FTEs

Group plans vs. individual plans

QuestionEmployer group planIndividual plan
Who chooses the options?The employer selects one plan or a menu of plans for eligible employees.The individual chooses from plans available in their residential service area.
Who pays?The employer commonly pays part of the employee premium; employees may pay the balance and dependent costs.The individual or family pays, potentially with Marketplace premium tax credits if eligible.
Medical historyACA-compliant group coverage generally cannot price an individual employee based on health status.ACA-compliant individual coverage accepts applicants regardless of pre-existing conditions; some non-ACA products may underwrite.
Enrollment timingNew hires enroll after the waiting period; existing employees generally change elections during annual enrollment or qualifying events.ACA Marketplace enrollment generally occurs during Open Enrollment or a Special Enrollment Period.
Plan portabilityCoverage is tied to employment and plan eligibility; COBRA or state continuation may be available after loss.Coverage belongs to the individual but may need to change after moving outside the plan's service area.
Tax treatmentEmployer contributions are generally deductible business expenses, and qualifying employee contributions may be made pre-tax through a cafeteria plan.Tax treatment depends on eligibility, income, self-employment status and whether coverage is purchased through the Marketplace.
Choice and networkChoice is limited to the employer's offering, but group products may provide broader regional or national networks.Choice depends on carriers and networks available in the person's home ZIP code.

Specific plan rules, network access, tax treatment and availability vary by employer, carrier, state and funding arrangement.

Can a group plan provide tax benefits?

01

Employer deduction

Employer-paid health-plan costs are generally treated as deductible business expenses, subject to entity structure and tax rules.

02

Employee tax exclusion

Employer-provided health coverage is generally excluded from an employee's federal taxable income. A properly established Section 125 cafeteria plan may allow qualifying employee premium contributions on a pre-tax basis.

03

Small-business tax credit

Eligible employers with fewer than 25 full-time-equivalent employees may qualify for a credit. The maximum is generally 50% of qualifying employer premium payments—or 35% for eligible tax-exempt employers—typically through SHOP and for a limited period.

!

Ownership rules differ

S-corporation shareholders owning more than 2%, partners, sole proprietors and family employees may receive different tax treatment.

$

Subsidy tradeoff

An affordable employer offer can affect an employee's eligibility for Marketplace premium tax credits. Compare household effects before changing arrangements.

CPA

Confirm before acting

A broker can explain coverage, but the employer's CPA or benefits counsel should confirm deductions, credits, payroll setup and entity-specific treatment.

Different funding arrangements create different risks.

Fully insured

The carrier assumes claims risk

The employer pays a fixed premium to an insurance carrier. The carrier pays covered claims under the policy.

  • More predictable monthly premium
  • State insurance rules generally apply
  • Renewals reflect carrier pricing and group factors
Level-funded

Fixed monthly funding with reconciliation

The employer pays a level amount covering expected claims, administration and stop-loss protection. Contract terms determine whether a surplus may be returned and how deficits are handled.

  • Potential savings for favorable claims
  • More complexity than fully insured
  • Underwriting and participation rules may apply
Self-funded

The employer assumes claims risk

The employer pays employee claims, commonly with stop-loss coverage and a third-party administrator.

  • Greater plan-design control
  • Potential access to claims data
  • Higher financial and compliance responsibility
HRA strategy

Employer-funded individual coverage

QSEHRA or ICHRA arrangements can reimburse eligible individual premiums and medical expenses under federal rules.

  • Can fit distributed workforces
  • Defined employer contribution
  • Requires formal documents and compliance

Can one group plan cover everyone?

Yes, sometimes. A single group policy can cover employees in different states when the carrier permits it and the provider network works in every employee location.

A national PPO or multi-state network may make this practical. A local HMO may leave remote employees with emergency-only access or no useful routine-care network. Carrier rules, the employer's primary business location, employee residence and state insurance requirements all matter.

1
Map employee ZIP codes

List every employee location and expected future hiring state.

2
Test the exact network

Search primary care, hospitals, specialists and pharmacies near each employee.

3
Confirm carrier eligibility

Ask whether out-of-state employees can enroll and whether a minimum number must be located in the policy's situs state.

4
Consider alternatives

If one network cannot serve everyone, compare multiple plan options, a national carrier, ICHRA, QSEHRA or another compliant strategy.

Pros and cons of group health insurance

Potential advantages

  • Stronger recruiting and employee retention

  • Multi-state networks can be difficult for distributed teams
  • ERISA, ACA, COBRA, payroll and notice responsibilities may apply

Can an employer cancel a group plan at any time?

Usually not instantly.

An employer can generally decide to stop offering a plan prospectively, but must follow the insurance contract, plan documents, employment commitments and applicable federal and state notice and continuation rules.

Check the carrier contract

Termination dates, advance notice, minimum participation, premium obligations and renewal terms vary. Midmonth or retroactive cancellation may not be permitted.

Give employees clear advance notice

Employees need time to understand when coverage ends and evaluate a spouse's plan, Marketplace Special Enrollment or other coverage. Some material plan changes trigger specific notice requirements.

Handle COBRA or state continuation

Federal COBRA generally applies to private-sector group health plans of employers with at least 20 employees in the prior year. State continuation laws may apply to smaller employers.

Respect payroll and cafeteria-plan rules

Employee pre-tax elections, deductions, refunds and midyear changes must be handled correctly.

Avoid a coverage gap

If replacing the plan, coordinate the old termination date with the new effective date and do not cancel until the replacement is confirmed.
