Small Business Health Insurance in Illinois
Illinois employers with up to 50 employees can offer health benefits three ways: a fully insured small-group plan, an individual coverage HRA that reimburses each employee's own plan, or a QSEHRA for businesses under 50 full-time employees. Which one fits depends on your budget, how many people you cover and how the Illinois small-group market is priced for 2027.
Private health insurance in Illinois
Most people I help in Illinois end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.
Why people leave the Marketplace
- Premiums keep climbing. Illinois Marketplace premiums are rising 14% to 14.1% on average for 2027.
- The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
- Surprise tax bills. Underestimate your income and you repay the tax credit in April.
- Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
- High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
- One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.
What a private plan does differently
- Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
- Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside Illinois too. Networks vary by plan.
- Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
- Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
- Approval is based on health. You answer health questions, and acceptance is not guaranteed.
With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.
Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

The Illinois small-group market for 2027
The Illinois Department of Insurance approved 2027 small-group increases averaging about 17.6 percent across seven filings, two points more than the 15.6 percent insurers first requested, because the review raised one insurer's request rather than trimming it. Results vary widely by filing, from under 7 percent to almost 18 percent, so two businesses with the same headcount can see very different renewals depending on their insurer. The Department posts each final decision letter online, which lets an owner check the approved range before accepting a renewal or shopping elsewhere.
Illinois options and rules for small employers
Illinois's continuation law reaches small employers too: Section 367e has no size cutoff, so even a three-person company with an insured plan must offer departing workers up to 12 months on the group plan, and Section 367.2 adds rights for divorced, widowed and retirees' spouses. Self-funded plans fall outside these rules. Because Illinois income tax starts from federal AGI, reimbursements from an individual coverage HRA or a QSEHRA that are tax-free federally stay tax-free on the Illinois return, which makes either arrangement a practical alternative to a 2027 group renewal near 18 percent.
Illinois at a glance for owners and employees
Illinois buyers use Get Covered Illinois, the state's own exchange since the 2026 plan year. Final 2027 individual rates rise about 14 percent on average across five insurers, and two insurers are leaving the exchange, so some enrollees must pick new plans. Illinois now requires prior approval of individual and small-group rates. The state banned short-term plans in 2025, so the alternatives to Marketplace coverage are private, medically underwritten plans and employer or union coverage. Continuation rights are relatively strong: 12 months for employees, and up to two years, or until Medicare for those 55 and older, for divorced or widowed spouses.
Other Illinois rules to know
- Leaving a small employer: Illinois requires insured group plans to offer up to 12 months of continuation after three months of coverage, and gives divorced or widowed spouses up to two years, or until Medicare if they are 55 or older.
- Short-term plans: Illinois banned new short-term health plans starting January 1, 2025.
- Where to enroll: Illinois uses its own exchange, Get Covered Illinois, which replaced HealthCare.gov for 2026. Get Covered Illinois sets its own open enrollment dates; check its site for 2027 deadlines. Private, medically underwritten plans can start the first of any month if approved.
- 2027 rates: individual plans 14% to 14.1% on average, small-group plans about 17.6%. See the Illinois 2027 rate page.
Group plan or HRA
A small-group plan gives everyone the same coverage and usually requires a minimum share of employees to enroll and a minimum employer contribution. An ICHRA lets you set a monthly allowance by employee class and lets each person pick their own individual plan; it works for any size business. A QSEHRA is simpler and capped by annual limits, for employers under 50 full-time employees. Employees offered an affordable ICHRA lose access to the Marketplace tax credit, so set the allowance with that in mind.
Covering the owner
An owner-only business cannot buy a small-group plan in most states; it needs at least one eligible employee who is not an owner or an owner's spouse. Until then the owner buys individual coverage. Once you have employees, you can usually join the group plan or the ICHRA as well.
Tax treatment
Employer contributions to group premiums and HRA reimbursements are generally deductible to the business and tax-free to employees. General information, not tax advice — confirm with your CPA based on your specific entity structure.
For 2027 the Marketplace credit stops at 400 percent of the poverty level: $63,840 for one person, $86,560 for two and $132,000 for a family of four. The out-of-pocket maximum for 2027 Marketplace plans is $12,000 for one person and $24,000 for a family. The full guide covers the rest.
