Mississippi 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 Mississippi, 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
Mississippi's average 2027 rate change is 20.2% (finalized). The details are on the Mississippi 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. Mississippi parents above the line pay full price at every metal level, which is when a side-by-side comparison matters most.
Mississippi this year
Mississippi families who stayed on the Marketplace after the larger subsidies ended now face a second straight year of big increases: about 20 percent approved for 2027, among the largest on my list. Three insurers continue, so choices are limited nearly everywhere. Hospital access varies sharply between Jackson, the Gulf Coast, DeSoto County, Hattiesburg and the Delta, so for a family with children the network deserves the first look. The HealthCare.gov window for Mississippi closes January 15. Once a four-person household passes $132,000, the subsidy is gone and the full increase is theirs.
One thing to do before you choose
DeSoto County parents who take kids to Memphis hospitals, and Gulf Coast families who use specialists in Mobile or New Orleans, need a network that crosses into Tennessee, Alabama or Louisiana. With only three insurers, the plan you get auto-renewed into may look different from what you picked, so compare all three for your county before December 15 and check every doctor your children see.
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 Mississippi?
January 15, 2027 on HealthCare.gov. Choose by December 15, 2026 for coverage that starts January 1; plans picked after that start February 1.
Can a Mississippi family plan cover a children's hospital in Memphis?
Some plans include out-of-state hospitals and some do not, so search for that exact hospital in every plan you consider. With three insurers in Mississippi, compare all of them for your county. Healthy families over the income limit can also price a private plan, subject to approval.
Can I get a private plan in Mississippi 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.
