ICHRA in Missouri 2026: Every County Qualifies

Does ICHRA beat small group in Missouri?

Yes, nearly everywhere, though not by the same amount everywhere. An ICHRA (Individual Coverage Health Reimbursement Arrangement) currently beats traditional small-group coverage in an estimated 115 of Missouri's 115 counties, including the independent City of St. Louis, for the 2026 plan year, based on a county-by-county comparison of individual-market and small-group benchmark premiums. Those 115 counties make up about 9% of the 1309 counties nationwide where the math currently favors ICHRA, and cover essentially the entire state's population.

If you haven't worked through the general decision yet, our ICHRA vs. small group decision guide walks through the framework this article applies specifically to Missouri. Here's the part a simple "Missouri qualifies" headline hides: qualifying isn't binary in this state, it's a spectrum. The Kansas City metro's core counties clear a 27.6% spread. St. Louis clears 16.6%. Springfield's Greene County clears 19.7%. And a handful of small counties along the Iowa border, DeKalb and Caldwell among them, clear the bar by less than 4 percentage points, worth under $400 a year per employee. All of them "qualify." Only some of them make the exercise worth running.

Why Missouri's 2027 rate filings matter now

Missouri's small-group employers are looking at another round of increases before this year's renewal even settles. The state's insurers have filed preliminary 2027 small-group rate requests averaging a weighted 16.5% increase, and individual-market carriers filed averaging 12.4%, according to rate data compiled by ACA Signups from Missouri Department of Commerce and Insurance (DCI) and SERFF filings. The Missouri DCI opened these preliminary filings for public comment through August 31, 2026, and expects to post final, approved rates no later than October 31, 2026. Eight carriers plan to continue selling individual-market coverage in Missouri for 2027, with at least two carriers offering plans on and off the exchange in every county; four carriers will offer small-group plans off the exchange, and National Health Insurance Co. appears to be dropping out of that market.

Neither the 12.4% nor the 16.5% figure is final. Missouri's Department of Commerce and Insurance reviews every filing before approving anything, and rates can move in either direction once that review closes. Still, a filed 16.5% small-group increase, on the heels of already-rising premiums, is the specific, dated reason an ICHRA conversation is worth having in Missouri right now, not a generic "costs are rising" claim.

This matters for an ICHRA specifically because ICHRA reimbursements ride on individual-market prices, not small-group prices. When small-group rates move up sharply, as filed for Missouri's 2027 plan year, the spread this entire strategy depends on can widen, even if individual-market rates rise too, so long as they don't rise as fast. That's exactly why every figure in this article is tied to a specific plan year and why we rebuild the underlying dataset every year rather than reusing prior numbers.

The individual-market filings, carrier by carrier

The 12.4% figure for 2027 is a weighted statewide average across a field of eight continuing carriers. Celtic Insurance Co., which sells as Ambetter, is by far Missouri's largest individual-market carrier by enrollment, covering an estimated 151,880 members, and filed one of the smaller requested increases at 10.3%. Blue Cross Blue Shield of Kansas City filed 10.6% on about 5,416 members, and Bankers Reserve Life Insurance Co. filed 11.3% on about 2,442 members. Healthy Alliance Life Insurance Co., covering an estimated 40,000 members, filed 12.67%. Oscar Insurance Co. filed 15.9% on about 18,672 members, and UnitedHealthcare filed 16.5%, though its Missouri enrollee count wasn't broken out in the filing. Medica Insurance Co. filed the steepest increase among continuing carriers at 25.6%, on a comparatively small block of about 12,843 members. Separately, Cox Health Systems Insurance Co. cited underlying health care cost trend running about 9.9% a year as part of its filing rationale, a different figure from a requested rate change.

Because Celtic/Ambetter's enormous enrollment base filed near the bottom of the range, it pulls the statewide weighted average down toward 12.4% even though five of the seven listed carriers filed above that number. An employer whose current individual-market plan sits with Medica or Oscar is looking at a materially steeper filed increase than the statewide average implies, a reminder that "the state average" and "your employees' actual plan" are not the same number.

All 115 counties and cities, ranked

Missouri's qualifying list isn't confined to its two big metros. It runs from the Kansas City and St. Louis metro cores, through Springfield and Joplin in the southwest, up to St. Joseph in the northwest, and across most of the state's small rural counties. Savings for 2026 run from about 3.7% to 27.6% below the small-group benchmark, averaging 16.6% across all 115 qualifying counties and the City of St. Louis.

St. Louis County, Missouri's largest county by population at nearly a million residents, qualifies at 16.6%. Jackson County, anchoring the Kansas City side of the state line, qualifies at a wider 27.6%, and shares that exact spread with its immediate suburban ring: Clay, Cass and Platte Counties. St. Charles County, a fast-growing St. Louis suburb, sits in the St. Louis-area benchmark group at 16.6% rather than the Kansas City one, a reminder that county-level rating areas, not simple geography, drive this math.

Why Kansas City saves more than St. Louis

Both of Missouri's major metros qualify, but Kansas City's spread runs meaningfully wider than St. Louis's, and the individual-market side of the equation isn't why. Jackson, Clay, Cass and Platte Counties, the Kansas City metro's core, share a 2026 individual-market benchmark of $613 a month, actually higher than St. Louis City and County's $561. What separates the two metros is the small-group side: Kansas City's small-group benchmark runs $847 a month against St. Louis's $673, a gap of more than $170 a month between the two metros' small-group pricing alone. That's why Kansas City clears 27.6% while St. Louis clears 16.6%: a pricier small-group market in the Kansas City rating area, not a cheaper individual market.

Springfield's Greene County lands in between at 19.7%, with an individual benchmark of $673 against a small-group benchmark of $838. Boone County, home to Columbia and the University of Missouri, qualifies at a much thinner 9.2%, a reminder that a college town with a large, comparatively young workforce can produce a narrower spread than either big metro.

Outside the two big metros, the picture is more mixed than either extreme. Jasper County, home to Joplin, qualifies at a middling 12.1%, an estimated $1,176 a year per employee. Buchanan County, anchoring St. Joseph in the state's northwest corner, qualifies closer to the St. Louis range at 16.6%, worth an estimated $1,944 a year. Neither city is a household name in ICHRA coverage the way Kansas City or St. Louis is, but both have real, qualifying spreads worth checking if you have staff based there.

A worked example: Kansas City versus St. Louis

Here's what the county-level math actually looks like for a small employer with a split Missouri workforce, using real 2026 rate data for two qualifying counties. Assume a 20-employee company with 12 employees in Jackson County (Kansas City metro) and 8 employees in St. Louis County (St. Louis metro).

Notice what this example does not do: claim a single statewide "Missouri saves X%" figure. A headline like that would blur the fact that the Kansas City side of this workforce is worth nearly $1,500 a year more per employee than the St. Louis side. Checking counties individually, not trusting a state average, is the entire argument for county-level data.

Scale the same math to a bigger, more realistic Missouri employer. A 50-person firm centered entirely on the Kansas City metro's qualifying counties could see an estimated $139,986 a year in aggregate savings if it funded ICHRA contributions at the benchmark level across the board (50 x $2,800). That isn't a guarantee. It assumes every employee enrolls in a plan priced near the benchmark, and real households will land above or below it depending on age, plan choice and household size. It is, however, a real number built from real 2026 rate data, not a sales estimate.

The affordability test, in plain numbers

Every ICHRA has to clear the IRS's affordability test to avoid pushing an eligible employee's premium tax credit decision the wrong way. Under IRS Revenue Procedure 2025-25, the required contribution percentage for plan years beginning in 2026 is 9.96% of household income, up from 9.02% for 2025. In plain terms: an employer's ICHRA is considered affordable for an employee if that employee's own required monthly contribution toward the lowest-cost silver plan in their rating area doesn't exceed 9.96% of their household income, divided by 12.

That waiver decision matters more this year than in the recent past. Enhanced federal premium tax credits expired at the end of 2025, and the 400% federal poverty line cliff is back for the 2026 plan year: under the Federal Register's January 2026 update to the HHS poverty guidelines, 400% of the poverty line for the 2026 guideline year is $63,840 for a single person and $132,000 for a family of four in the 48 contiguous states. A household over that line gets no premium tax credit at all, on or off an employer's ICHRA, which is part of why an employer-funded contribution has become a more meaningful offer for higher earners than it was when generous subsidies were available up and down the income scale.

Why more Missouri employers are looking at this now

Missouri's rate filings aren't happening in a vacuum. The HRA Council, an industry association that aggregates anonymized enrollment data from its member organizations, released its newest annual report on August 12, 2026: Growth Trends for ICHRA & QSEHRA, Vol. 5. It found that more than 20,000 US businesses now offer ICHRA or QSEHRA, covering at least 500,000 employees nationally, with ICHRA-covered lives alone surpassing 500,000 for the first time at the start of 2026. Among small employers, more than two-thirds of those offering ICHRA, and 93% of those newly offering QSEHRA in 2026, had previously offered no health coverage at all. Applicable Large Employers were the fastest-growing segment, more than doubling their average ICHRA adoption since the prior year.

That distinction matters for a Missouri employer weighing this for the first time. On the current individual marketplace, Missouri's 2026 open enrollment saw 365,734 plan selections statewide, down from 417,000 during the 2025 open enrollment period, a roughly 12.3% year-over-year decline, according to KFF's Marketplace Enrollment Snapshot for the 2026 open enrollment period. For most small businesses in the state's qualifying counties, the realistic comparison isn't "ICHRA versus our current group plan." It's "ICHRA versus offering nothing," which is a much easier case to make when you're competing for talent against employers who already offer some kind of benefit, and a more urgent one with small-group rates already filed up 16.5% for 2027. The IRS, DOL and HHS final rule that created ICHRA in 2020 sets no employer size minimum at all; a single-employee company can offer one on the same terms as a 500-person company, part of why adoption keeps climbing fastest among the smallest employers in the HRA Council's data.

How ICHRA Savings helps

None of the county math above requires talking to anyone. The savings map lets you look up every Missouri county by name and see the same individual-market and small-group benchmark premiums used in this article, so you can check whether your specific workforce sits inside a strong-margin county, a thin-margin one, or somewhere in between before you spend time on anything else. Beyond the map, we help employers design and set up an ICHRA: building employee classes correctly, modeling affordability against your real census instead of a rule of thumb, and getting the required employee notice right and on time. We don't pick your employees' plans for them; that decision, and the choice of network, stays with each person buying their own coverage. Our part is the budget, the design and the compliance scaffolding around it.

Before anything else, check whether your county is one where this works well: https://ichrasavings.com/ichra-savings-map/. Ten minutes there tells you whether the rest of this process is worth starting, and whether your county lands closer to Kansas City's 27.6% or DeKalb's 3.7%.

One more wrinkle worth flagging for Missouri specifically: both major metros straddle a state line. The Kansas City metro spans Jackson, Clay, Cass and Platte Counties on the Missouri side, and Johnson and Wyandotte Counties on the Kansas side. St. Louis touches Illinois across the Mississippi River. An employer with staff living on either side of either line needs each employee's actual county checked individually, since Kansas and Illinois run their own separate rate filings and their own separate qualifying counties on our savings map, not a mirror of Missouri's numbers.

Setting up an ICHRA in Missouri

Missouri doesn't add state-specific ICHRA rules on top of the federal framework. The same IRS, DOL and HHS final rule that governs ICHRA everywhere applies here, and the setup sequence is identical to any other state:

1. Pull your census by county, not by office address. A company headquartered in St. Louis with field or remote staff in the Kansas City metro or Springfield has a materially different savings story per location.
2. Check each employee's county on the savings map. Don't assume a statewide average applies; a 27.6% metro and a 3.7% rural county both technically "qualify," but they aren't the same decision.
3. Model affordability using the 2026 threshold. At 9.96% of household income, the required contribution percentage sets how much an ICHRA contribution needs to cover to count as affordable.
4. Define employee classes carefully, if you use them. An employee class is a group defined by an objective factor the IRS permits, such as full-time versus part-time status, geographic location, or salaried versus hourly work. Class rules carry minimum-size requirements and cannot offer the same class a choice between ICHRA and group coverage.
5. Send the required notice on time. Under the federal ICHRA final rule, eligible employees generally need written notice at least 90 days before the plan year starts, with specific required content about the offer and its effect on subsidy eligibility.
6. Budget for onboarding support. Employees who have never shopped Missouri's individual marketplace on their own need guidance, once, at enrollment, especially with eight carriers competing statewide and coverage options varying meaningfully by county.

The honest limits of this data

How these numbers are calculated

Every county figure in this article comes from the same dataset that powers our savings map, not from a survey or a sales estimate. For each of Missouri's 115 counties and its one independent city, we compare a 2026 individual-market benchmark premium, the second-lowest-cost silver plan available to a representative 50-year-old enrollee, against a small-group benchmark premium built from comparable small-group plan filings for that county's rating area. A county "qualifies" when the individual benchmark sits below the small-group benchmark; the percentage and dollar savings figures in this article are the gap between those two numbers, expressed as an annual per-employee figure at 12 times the monthly difference. The separate 2026 and 2027 rate-filing figures in this article come from Missouri Department of Commerce and Insurance and SERFF filings as compiled by ACA Signups, and are not reflected in the county-level qualifying dataset above, which uses the 2026 benchmark comparison described here.

Three limitations are worth stating plainly. First, benchmark premiums are built around a representative enrollee profile, so an unusually young or unusually old workforce will see a different real-world spread than the county average implies. Second, these are benchmark plans, not every plan on the market; an employee who chooses a richer or leaner plan than the benchmark will see a different premium, though the relative spread tends to hold directionally. Third, rates are filed and refreshed annually, so a county that qualifies for 2026 is not guaranteed to qualify for 2027 once the current filings are approved. We rebuild this dataset each plan year rather than reusing prior-year figures, and we recommend employers do the same before every renewal.
