Small business health insurance in Michigan

How Michigan's market is set up

Michigan uses the federally facilitated marketplace at HealthCare.gov (KFF). For 2026, 116 health plans are available on the marketplace and 191 across the whole individual market including off-marketplace plans (Michigan DIFS, November 6, 2025). Six insurers offer on-marketplace individual plans in 2026, down from nine — Michigan and Illinois saw the largest net carrier losses in the country, with as many as three carriers leaving some counties (KFF, June 2026). Ten insurers filed 2026 individual-market rates in total, counting off-marketplace carriers (DIFS, 2026 Approved Rate Changes).

Rates may vary only by rating area, age within a 3:1 ratio, and tobacco use within 1.5:1, and Michigan requires per-member rating in the small-group market (DIFS Bulletin 2026-14-INS). DIFS reviews small-group rates for employer groups up to 50 employees. CMS divides the state's 83 counties into 16 rating areas.

What a Michigan group plan costs in 2026

DIFS approved an average 20.2% increase across the 2026 individual market, ranging from 9.3% (Oscar) to 25.8% (UnitedHealthcare Community Plan), with Blue Cross Blue Shield of Michigan at 24.0%, Blue Care Network at 23.3%, and Priority Health at 19.2%. For the small-group market, DIFS approved an average 11.1% increase across ten insurers, ranging from 7.0% to 16.2% (DIFS, 2026 Approved Rate Changes). The department says its review left approved rates about $250 million below what insurers requested (DIFS, November 6, 2025).

Two things follow for a Michigan employer. A group renewal in the 7–16% range is the market, not your carrier being unusual. And the individual market's 20% rise raises the allowance an ICHRA needs to stay affordable for older staff — the affordability test uses the lowest-cost Silver plan in the employee's rating area.

Per-member rating and what it means for your group premium

Michigan requires per-member rating in the small-group market: the group's premium is built by adding up each covered person's age-rated premium, not by applying one blended rate. In practice a young hire lowers the group's cost and an older hire raises it, and the renewal moves as the roster ages. An ICHRA works the same way by design — each employee's individual premium is age-rated — but the employer's cost is the allowance, which you set, rather than the sum of premiums, which you do not.

Your four real options as a Michigan employer

There are four ways to offer health insurance to employees in Michigan, and the state's market rules change how each one performs.

• A small-group plan (up to 50 employees) through a carrier or the SHOP route. Predictable coverage, age-rated premiums, annual renewals, participation and contribution minimums.
• A PEO, which pools your staff into its own group plan and bundles payroll and HR for a fee on top of premiums. See our ICHRA vs PEO comparison.
• A taxable stipend. Simple, but it is wages: you owe employer payroll tax on it, the employee owes income tax, and it does not count as an offer of coverage. See our guide to health insurance stipends.
• An ICHRA — a fixed, tax-free monthly allowance employees use to buy their own individual plan on or off HealthCare.gov. No participation minimum, no renewal negotiation, and the allowance is a number you choose.

The Healthy Michigan Plan and your lowest-paid staff

The Healthy Michigan Plan is Michigan's Medicaid expansion, covering adults 19–64 with income at or below 133% of the federal poverty level; work requirements begin January 1, 2027 (Michigan.gov, Healthy Michigan Plan). Employees under that line are generally covered there and outside the ICHRA question. Above it, an employee is subsidy-eligible on HealthCare.gov, and an affordable ICHRA offer replaces the subsidy — so check each lower-wage employee before setting the allowance.

Setting an ICHRA allowance in Michigan

Michigan rates individual premiums on the federal 3:1 age curve, so a 64-year-old's premium can be up to three times a 21-year-old's for the same plan. Federal ICHRA rules let you vary the allowance by age up to that same 3:1 ratio, and in an age-rated state that is usually the fair design: a flat allowance treats a 25-year-old and a 60-year-old very differently in real purchasing power.

Location matters too. With 16 rating areas, a Detroit-area premium and an Upper Peninsula premium are different numbers. In our 2026 calculator dataset (the figures shown on our ICHRA in Michigan page), the lowest-cost Silver plan for a 40-year-old in Michigan averages about $557/month, ranging from $385 to $769 across the state's 83 counties. That spread is why an allowance set from a statewide average fails the ACA affordability test in some counties and over-funds others.

Our ICHRA calculator uses those county-level 2026 lowest-cost Silver premiums by ZIP code, so you can see the affordability line for each employee before you set a number. For 2026, an offer is affordable when the employee's cost for the lowest-cost Silver plan, minus your allowance, is no more than 9.96% of the applicable income measure (IRS).

Group plan vs. ICHRA for a Michigan employer

With three carriers gone from the marketplace and a 20% individual-market increase, Michigan is not a state where an ICHRA is automatically cheaper. It is a state where control matters: the group market rose 11% and will rise again, and per-member rating means your renewal tracks your roster's age. The table puts the two side by side.

How to set up an ICHRA in Michigan

The setup is the same federal process as anywhere: adopt a written plan document, define employee classes, set the allowance (by age band and rating area if you choose), deliver the required employee notice at least 90 days before the plan year begins, and reimburse against proof of individual coverage. Give employees a clear enrollment path — HealthCare.gov or an off-exchange carrier — and time the launch to a window when they can actually enroll: the annual open enrollment, or the special enrollment period that a new ICHRA offer triggers.
