Illinois Mini-COBRA: Illinois continuation covers employers with 2-19 employees for up to 12 months

Step 1 — Your Situation

About Your Coverage Loss

Enter details about your current situation so we can calculate your COBRA costs and show you all available options in Illinois.

Number of Employees at Company ?The total number of employees at your former employer. Federal COBRA applies to employers with 20+ employees. Smaller employers may be covered by Illinois's state continuation laws.Source: COBRA (P.L. 99-272); Illinois continuation coverage law

Qualifying Event ?The event that caused loss of coverage. This determines your coverage duration: 18 months for most events, 36 months for divorce, dependent aging out, or Medicare entitlement. Involuntary termination (not for gross misconduct) and voluntary termination both qualify.Source: 29 U.S.C. 1163; DOL COBRA guidance

Coverage Tier ?The level of coverage you had on your employer's plan. Family coverage is the most expensive COBRA option. You can elect a lesser tier (e.g., switch from Family to Employee Only) to reduce costs.Source: DOL COBRA FAQ; 29 CFR 2590.606

Plan Type ?Your current health plan type affects marketplace comparison. PPOs are typically more expensive; HDHPs are cheaper but require higher out-of-pocket spending. This helps us compare equivalent coverage options.Source: KFF 2025 Employer Health Benefits Survey

Step 2 — Current Plan Details

Your Employer Health Plan Costs

Enter the full cost of your employer health plan. You can find the total monthly premium on your Summary of Benefits and Coverage (SBC) or by asking HR.

Total Monthly Premium ?The TOTAL monthly premium your employer pays for your health plan (employer + employee share combined). This is NOT just your paycheck deduction — it includes the employer contribution. Find this on your SBC or benefits summary. COBRA is based on this full amount.Source: 29 U.S.C. 1162(2); DOL COBRA Model Notices

Employer Contribution 75% ?What percentage of the premium your employer pays. The national average is about 83% for single coverage and 73% for family coverage. This determines the gap between what you were paying and what COBRA costs.Source: KFF 2025 EHBS; average employer contributions

Spouse has employer plan available ?If your spouse has access to an employer-sponsored health plan, this may be a more affordable alternative to COBRA. A qualifying life event (like job loss) creates a special enrollment period for your spouse's plan.Source: 29 CFR 2590.701-6; HIPAA special enrollment rights
