Michigan Open Enrollment 2027 for Families
Last updated November 3, 2026 · By Frank Caballero, licensed health insurance broker
Short answer
For families buying their own coverage in Michigan, open enrollment for 2027 coverage runs November 1, 2026 to January 15, 2027 on HealthCare.gov, and December 15 is the date to choose by for a January 1 start. A private, medically underwritten plan for the household does not wait for the window either: if approved, it can start the first of any month.
What 2027 looks like for you
Michigan's average 2027 rate change is 14.5% (finalized). The details are on the Michigan 2027 premium increase page.
The 2027 subsidy line rises with household size: $109,280 for a household of three, $132,000 for four, and higher for larger families. Marketplace plans charge for at most three children under 21, so a bigger family's premium stops growing after the third child. Michigan parents above the line pay full price at every metal level, which is when a side-by-side comparison matters most.
Michigan this year
Michigan families face a finalized 2027 average increase of about 14.5 percent in a market more competitive than most, built heavily on regional HMOs tied to hospital systems in Detroit, Grand Rapids, Lansing and Ann Arbor. Those plans work well close to home and poorly elsewhere, which matters for the many Michiganders who spend winters in Florida with school-age kids along. Michigan uses HealthCare.gov, open now through January 15, and December 15 is the last day to lock in a plan that starts with the year. No subsidy reaches a four-person household earning over $132,000, so contract engineers and small-business parents in that range cover the whole bill.
One thing to do before you choose
If your family splits the year between Michigan and Florida, check whether the plan covers anything beyond emergencies down south, especially a pediatrician visit or a child's prescription refill. I am licensed in both states, so one review can cover both homes. Upper Peninsula families who use Wisconsin hospitals and Detroit-area parents near Ohio should confirm the network reaches the doctors they actually use.
Your checklist
- Each family member's doctors and the children's hospital you use
- The family deductible and out-of-pocket maximum
- Household income against your household-size line
- Planned 2027 care: a pregnancy, braces or surgery
Private plan or Marketplace?
Private plan
Whole household healthy, income above the line: each person is approved on their own health answers; not an ACA Marketplace plan.
Marketplace
Ongoing care for a child or parent, or income under the line: HealthCare.gov accepts everyone, and the subsidy grows with household size.

Questions
When is the 2027 open enrollment deadline in Michigan?
January 15, 2027 on HealthCare.gov. Choose by December 15, 2026 for coverage that starts January 1; plans picked after that start February 1.
We winter in Florida with our kids. Will a Michigan HMO cover their care there?
Often only emergencies. Many Michigan HMOs are tied to in-state hospital systems, so routine visits in Florida may not be covered. A plan with a broader network can work in both states. Because I am licensed in Michigan and Florida, we can compare options for both homes on one call.
Can I get a private plan in Michigan after open enrollment closes?
Yes. You can apply in any month and, if approved, a private plan can start the first of a month; the insurer can decline based on health answers.
