What changed for 2027
Missouri's 12.3 percent individual figure is final, while the 16.5 percent small-group average is the bigger story for employers. Missouri runs no state reinsurance program or state premium subsidy. More detail is on the Missouri 2027 premium increase page.
For Missouri households buying 2027 coverage, the Marketplace premium tax credit stops at 400% of the federal poverty level: $63,840 for one person, $86,560 for two, $109,280 for three and $132,000 for four. The repayment caps were removed starting with tax year 2026, so any excess advance credit is repaid in full on Form 8962. General information, not tax advice — confirm with your CPA based on your specific entity structure.
Who this year's window matters for in Missouri
Missouri's individual increase is a moderate 12.3 percent, now final, but small employers face about 16.5 percent on group renewals, so some owners in St. Louis and Kansas City are weighing individual plans for themselves and their staff this fall. Six insurers filed, one of them now selling only off the exchange, though the Ozarks and northern Missouri see fewer choices than the two metros.
Self-employed work that is common in Missouri, and the people I most often help there: owner-operator truck drivers on I-70 and I-44, construction trades, real estate agents, healthcare and IT contractors in Kansas City and St. Louis, small business owners, and cattle and row-crop farm families.
Before you renew in Missouri
Missourians in the St. Louis area who see doctors in Illinois, and Kansas City households with specialists on the Kansas side, should check that a 2027 plan covers both sides of the state line. Rural buyers in the Ozarks and the Bootheel often have fewer insurers per county, so the deductible and drug list deserve as much attention as the premium.
Should you renew, switch, or look at private?
Auto-renew risk
Do nothing and HealthCare.gov re-enrolls you at the new 2027 price, 12.3% higher on average in Missouri.
Healthy, income above the line
Price a private plan in Missouri too. If approved, it can start the first of any month, with no wait for Missouri's window.
Health conditions or subsidy-eligible income
Use the Marketplace. HealthCare.gov plans can't decline you or charge more for your health.
Checklist before you pick a plan
- Your Missouri renewal notice
- The new 2027 premium and deductible
- Doctors and prescriptions still in network, including any care in Kansas City or St. Louis
- Your 2027 income estimate
Missed it?
After Missouri's window closes, a Marketplace plan needs a special enrollment event: losing other coverage, a move, marriage or a baby, generally within 60 days, through HealthCare.gov. Check with Can I enroll now? or the missed open enrollment guide.
Leaving a job in Missouri? Missouri requires insured group plans of employers too small for federal COBRA to offer continuation in the same manner as federal COBRA, which generally means up to 18 months after leaving the job. It does not apply to self-funded employer plans.
Short-term plans, if you only need a bridge: Missouri law recognizes short-term major medical policies with terms of up to 12 months, and federal agencies are not prioritizing enforcement of the four-month federal limit, so plans longer than four months are sold in Missouri. They are not Marketplace coverage.
In Missouri, a private, medically underwritten plan needs no event. If approved, it starts the first of a month; approval is not guaranteed.

Missouri open enrollment questions
When does open enrollment end in Missouri for 2027?
January 15, 2027, on HealthCare.gov, the federal Marketplace. Pick a plan by December 15 for a January 1 start in Missouri.
What happens if I miss the December 15 deadline in Missouri?
You can still enroll through January 15, but a plan picked after December 15 starts February 1.
Can I get a private plan in Missouri outside open enrollment?
Yes. In Missouri you can apply in any month, and if approved, a private, medically underwritten plan starts the first of a month; the insurer can decline based on health.
Will I be auto-renewed in Missouri?
Usually, at the 2027 price: 12.3% higher on average.
Is there a fee to use a broker in Missouri?
No. Missouri clients pay nothing; the insurance company pays the broker, and Marketplace premiums are the same with or without one.
Should a Missouri small-business owner compare individual coverage this year?
Often, yes. With group renewals averaging about 16.5 percent, an individual plan for the owner, or reimbursing employees for individual plans through an ICHRA, is worth pricing against the renewal before you sign it.
