2026 Open Enrollment Guide: What Employers Need to Know

Open enrollment season represents one of the most important periods in the benefits calendar for employers and employees alike. Getting health insurance open enrollment 2026 right requires careful planning, clear communication, and understanding your obligations. This employer open enrollment guide walks you through everything you need to prepare for a successful enrollment period.

Understanding the 2026 Open Enrollment Timeline

For most employer-sponsored health plans, open enrollment runs during the fall months, typically between October and December for coverage beginning January 1, 2026. The exact dates depend on your plan's renewal schedule and the insurance carrier or platform you use.

Marketplace open enrollment through HealthCare.gov runs from November 1, 2025, through January 15, 2026, which matters if your employees might seek individual coverage or if you offer an Individual Coverage Health Reimbursement Arrangement.

Starting your internal preparations at least 60 to 90 days before enrollment opens gives you time to evaluate plan options, update materials, and train staff who will answer employee questions.

Why Open Enrollment Matters More in 2026

The stakes for health insurance open enrollment 2026 are particularly high given the current benefits landscape. According to the KFF 2025 Employer Health Benefits Survey, the average annual premium for employer-sponsored health insurance reached $9,325 for single coverage and $26,993 for family coverage. Early reports suggest cost trends will be even higher for 2026, potentially leading to significant premium increases unless employers find ways to offset costs through benefits changes.

The survey also found that 61% of workers at firms offering health benefits enrolled in coverage, with 80% of workers eligible for benefits and 76% of those eligible choosing to participate. These participation rates underscore how much employees value health coverage and why getting enrollment right matters.

Employer Open Enrollment Responsibilities

Understanding your employer's open enrollment responsibilities helps ensure compliance and creates a positive experience for your workforce.

Legal Compliance Requirements

Employers must provide certain notices and disclosures before and during enrollment. These include Summary of Benefits and Coverage documents for each plan option, notices about marketplace coverage availability, and HIPAA privacy notices. Missing deadlines or failing to distribute required documents can result in penalties.

For applicable large employers with 50 or more full-time equivalent employees, additional requirements around affordability and minimum value standards apply under the Affordable Care Act.

Plan Selection and Renewal

Before enrollment opens, evaluate your current plan performance. Review claims data, employee feedback, and cost trends. Decide whether to renew existing plans, switch carriers, or explore alternative arrangements like level-funded plans or ICHRA.

Negotiate with carriers or brokers to secure the best possible rates. Even modest improvements in premium costs or plan design can significantly impact both company budgets and employee satisfaction.

Employee Communication

Clear communication throughout the open enrollment process for employers ranks among the most critical responsibilities. Employees need to understand their options, deadlines, and any changes from the previous year.

Effective communication includes announcing enrollment dates well in advance, explaining plan options in plain language, highlighting any changes to premiums or benefits, providing resources for decision support, and offering multiple channels for questions.

The Open Enrollment Process for Employers: Step by Step

A structured approach to the open enrollment process for employers reduces stress and improves outcomes.

Phase 1: Preparation (60-90 Days Before)

Review your current benefits program and gather data on utilization, costs, and employee feedback. Evaluate plan options and finalize decisions about what you'll offer. Update all enrollment materials and train HR staff and managers on plan details and common questions.

Phase 2: Announcement (30 Days Before)

Communicate enrollment dates, plan options, and any changes to all eligible employees. Distribute Summary of Benefits and Coverage documents for each plan. Schedule benefits meetings or webinars to explain options.

Phase 3: Active Enrollment

Open your enrollment system and ensure employees can access decision support tools. Hold open sessions for questions and provide one-on-one support for employees with complex situations. Send reminder communications as deadlines approach.

Phase 4: Confirmation and Follow-Up

Confirm all elections before the deadline passes. Provide confirmation statements to employees showing their selected coverage. Submit enrollment data to carriers or administrators and address any discrepancies promptly.

Plan Options to Consider for 2026

Small business and enterprise employers alike should evaluate the full range of options available for 2026 coverage.

Traditional group health insurance remains the most common approach, but rising costs have pushed many employers toward alternatives. High-deductible health plans paired with HSA contributions can reduce premium expenses while building tax-advantaged savings for employees.

Level-funded arrangements combine elements of self-funding with stop-loss protection, offering potential savings for employers with healthier workforces. The KFF survey found 37% of covered workers at small firms now participate in level-funded plans.

ICHRA provides another path forward, allowing employers to offer tax-free allowances for employees to purchase individual coverage. This approach creates budget predictability for employers while giving employees freedom to select plans matching their personal needs.
