ICHRA in South Dakota 2026: Zero Counties Qualify

Does ICHRA beat small group in South Dakota?

Not yet, and we are going to say that plainly before anything else. An ICHRA (Individual Coverage Health Reimbursement Arrangement) is a way for an employer to give each employee a fixed monthly amount, tax-free, to buy their own individual health plan instead of enrolling everyone in one employer-chosen group plan. Whether that beats a traditional small-group plan on pure cost comes down to a single question: does the individual-market premium in an employee's county run meaningfully below the small-group premium there? For South Dakota, checked county by county against our qualifying bar of at least $100 a month per employee, the answer for the 2026 plan year is zero of the state's 66 counties.

If you found this page because you already know what ICHRA is and want the general decision framework, our ICHRA vs. small group decision guide covers that ground. This article applies it specifically to South Dakota, using the same county-level dataset behind every state page on this site, and it is written from Sioux Falls, where our advisor is based and where this same math applies to his own backyard.

That "zero" is not the whole story, and it is worth saying up front why we are publishing a post about a state where the headline savings case does not currently work. The honest version is more useful than a state-by-state highlight reel: South Dakota employers researching ICHRA deserve to know the real number before they spend time modeling a rollout, and the same county data that says "not here" also says exactly where, just across the state line, it does.

It also matters what "zero counties" does and does not mean. It does not mean South Dakota employees pay unusually high premiums, or that individual coverage here is a bad deal on its own terms. It means that, specifically compared against this state's small-group benchmark premiums, the individual side does not currently come in far enough below to clear the threshold this site uses to call a county a genuine cost-arbitrage opportunity. A county can miss that bar by a wide margin or a narrow one, and South Dakota's counties, as the next sections show, tend to sit closer to par than counties elsewhere with a wide, double-digit spread. That distinction is worth carrying through the rest of this article: "doesn't qualify" is a specific, narrow finding, not a verdict that ICHRA has nothing to offer a South Dakota employer.

What an ICHRA actually is

An ICHRA lets an employer of any size set a monthly reimbursement budget, and each employee uses it to buy their own plan on the individual market (a HealthCare.gov Marketplace plan or an off-exchange plan) and gets reimbursed tax-free for the premium and, if the employer allows it, other qualified medical expenses. It is a self-insured group health plan under IRS rules, created by a 2019 final rule from the Treasury/IRS, Department of Labor, and HHS, and it has no employer-size minimum: a five-person shop can offer one on the same legal terms as a five-hundred-person company. It is distinct from a QSEHRA (Qualified Small Employer HRA), a smaller HRA structure capped at a federal dollar limit that only employers with fewer than 50 employees and no group plan can use; ICHRA has no federal reimbursement cap and no employer-size ceiling. An employer cannot offer the same class of employees a choice between traditional group coverage and an ICHRA, though it can offer group coverage to one class (say, full-time staff) and an ICHRA to a different class (say, part-time or remote staff). ICHRA eligibility itself does not depend on whether a company is an ALE (Applicable Large Employer, generally an employer averaging 50 or more full-time-equivalent employees in the prior year, per IRS rules) or not; that status matters separately, because it decides whether the ACA's employer mandate, the requirement to offer affordable coverage or face a potential penalty, applies to a company at all. An ICHRA that clears the affordability test satisfies that mandate the same way traditional group coverage would.

Two more terms matter before the numbers do. An employee class is a group defined by an IRS-permitted factor, such as full-time versus part-time status, salaried versus hourly work, or geographic location, each of which can get its own ICHRA design and budget, subject to minimum-size rules. And substantiation is the paperwork side: before the first reimbursement and again with every claim, an employee has to show proof of individual coverage, either a document from the insurer or exchange or a signed attestation, which is what keeps the arrangement compliant as a tax-free benefit rather than taxable income.

Why South Dakota's math doesn't clear the bar

South Dakota's individual marketplace is thinner, in carrier terms, than many states where this site's math works well. For the 2026 plan year, exactly three insurers write ACA-compliant individual plans in the state: Avera Health Plans and Sanford Health Plan, both statewide, and Wellmark Blue Cross Blue Shield of South Dakota, which the South Dakota Division of Insurance lists as active in 39 of the state's 66 counties. Both Avera and Sanford are the insurance arms of South Dakota's two dominant integrated health systems, which also run the hospitals and clinic networks much of the state uses. Three insurers is not unusually low by national standards, but it is fewer choices than drive some of the widest ICHRA-favoring spreads on this site, and less competition on the individual side tends to keep individual premiums from falling as far below group premiums as they do in more competitive markets.

The 2026 marketplace open enrollment period for South Dakota, like every state using HealthCare.gov, ran from November 1, 2025 through January 15, 2026, per the South Dakota Division of Insurance. That timing does not change the rate math, but it does set the calendar an employer needs to work around if the plan is to enroll employees who want to shop the individual market for the first time.

None of this means South Dakota's individual market is expensive in absolute terms, or that the state's small-group plans are unusually cheap. It means that, for the 2026 plan year, the gap this site's method looks for, individual-market benchmark pricing running meaningfully below small-group benchmark pricing, has not opened up here the way it has in a majority of U.S. counties nationally, where 1309 counties currently qualify.

There is also a structural wrinkle specific to South Dakota worth naming: Avera and Sanford are not just the two largest individual-market insurers, they are vertically integrated with the two health systems that operate most of the state's hospitals and clinics. That arrangement is common in rural, low-density states, where a small population spread across a large geography makes it hard to sustain more than a couple of competing full-service systems. It is not, by itself, evidence of anything improper; it simply means the price competition this site's method depends on, several insurers bidding against each other for the same individual-market enrollees, has fewer independent players pushing on it here than in a state with a dozen ACA carriers. Rate area pricing compounds that: South Dakota's individual-market premiums are set by geographic pricing zone rather than by county alone, so a wide swath of counties inside the same rate area can price identically, the same mechanism our sister article on how rating areas create identical premiums across different counties covers in Ohio.

What coverage actually costs today

A useful number to anchor the rest of this article: South Dakota's statewide benchmark silver premium, the second-lowest-cost silver plan for a 40-year-old, runs an estimated $655 a month for the 2026 plan year, according to KFF's Marketplace Average Benchmark Premiums tracker. That is the individual side of the comparison. The site's own dataset builds the small-group side from comparable small-group plan filings by rating area, and for every one of South Dakota's 66 counties, that small-group benchmark comes in at or below the individual benchmark, which is the literal definition of "zero qualifying counties" here. We are not publishing a South Dakota-specific small-group dollar figure in this article, because no public filing source breaks it out the way individual-market rate filings are broken out; the qualifying calculation itself, built from the same Ideon and CMS-cross-verified data behind every other state on this site, is what backs the zero.

What next door looks like

Here is the part a flat "South Dakota doesn't work" headline would hide: drive two hours southwest from the Black Hills and the answer flips. Three Nebraska Panhandle counties that share a border with South Dakota, Dawes, Sheridan, and Sioux Counties, all clear our qualifying bar at an identical 16.4% estimated savings for 2026, worth about $2,115 a year per employee. Nebraska's Cherry County, also on the border, clears at a thinner 5.0%, about $569 a year. All four counties share the same individual-market benchmark premium ($896 a month), which points to a shared rate area; what changes county to county is the small-group side of the comparison.

This matters beyond curiosity. A South Dakota company headquartered in Rapid City (Pennington County) that employs even one remote worker living across the line in Dawes, Sheridan, or Sioux County, Nebraska, has a real, dataset-backed ICHRA case for that person, even though the company's own home county shows nothing. Our guide to ICHRA for remote teams across multiple states walks through exactly this kind of split workforce in more detail.

It is also a useful reminder for how HR and finance teams should actually run this check. It is tempting to look up a single state and treat the answer as final, the way a news headline might. The underlying dataset does not work that way; it is built county by county, and a state line is a political boundary, not an economic one. Rate areas, hospital networks, and insurer service territories routinely cross state lines without lining up with them, which is exactly why South Dakota and its nearest Nebraska neighbors can price so differently while sitting a short drive apart.

Here is what that looks like arithmetically for a real company. Say a 12-employee South Dakota business is headquartered in Rapid City (Pennington County), with 10 employees living locally and 2 working remotely from Sheridan County, Nebraska, just across the state line.

Widen that same company by one more remote hire in Dawes or Sioux County and the number moves again, in either direction, depending on where that person lives. That's the entire point of checking every county individually instead of asking "does ICHRA work in South Dakota" as if it had one answer.

What the 2027 filings show

Rates are refreshed every plan year, and South Dakota's next cycle is already partway filed. Insurers have submitted preliminary 2027 rate requests showing a weighted individual-market average increase of about 10.9% against an unweighted small-group average increase of about 14.2%, according to ACA Signups' compilation of the federal Rate Review database. By carrier: Avera Health Plans requested an average 11.7% individual increase, covering roughly 21,516 members, effective January 1, 2027. Sanford Health Plan requested 11.76% for its TRUE product and 11.45% for its Simplicity product, covering roughly 17,910 members as of March 2026, also effective January 1, 2027. Wellmark's specific requested rate was not disclosed in the public filing summary; its South Dakota individual book covers roughly 8,000 members.

If your county isn't there

The fix is not a trick, and we are not going to pretend the rate-spread math says something it doesn't. Here is the real method, in order.

1. Check every employee's actual county, not your office address. A South Dakota employer with even one remote hire, contractor-turned-employee, or field worker living outside the state can have a genuinely different answer for that person, as the Nebraska Panhandle counties above show.
2. Separate the cost-arbitrage question from the other four reasons employers choose ICHRA. A fixed, employer-chosen monthly budget instead of a carrier-set annual renewal; no carrier participation minimum, which matters for a small South Dakota team where a few employees are on a spouse's plan; coverage that travels with anyone who works remotely or moves; and, for a company offering no benefit today, a real benefit at any size, starting at one employee. None of those depend on the individual market being cheaper than group.
3. If you're a company under 50 employees with no group plan today, look at QSEHRA too. Its federal reimbursement caps are lower than an uncapped ICHRA, but it is simpler to administer for a very small team weighing "something" against "nothing."
4. Recheck after 2027 rates are approved, not just once. With small-group filings currently running ahead of individual-market filings, the gap could move before your next renewal. We rebuild the underlying dataset every plan year specifically so this check stays current.
5. If you still want to run the ICHRA math yourself, model your real census. County benchmarks describe the market; your workforce's actual ages, family sizes, and plan choices decide your real number.

How ICHRA Savings helps

None of the county math above requires talking to anyone. The savings map lets you look up South Dakota, Nebraska, or any other U.S. county by name and see the same individual-market and small-group benchmark premiums used in this article, so you can check every county where you actually have an employee before spending time on anything else. Where we help past that: designing employee classes that hold up (geography-based classes are the relevant tool for a South Dakota employer with even one out-of-state remote hire), modeling affordability against a real census rather than a rule of thumb, and getting the required employee notice right and on time if the math and the workforce shape make ICHRA a fit. We don't pick anyone's individual plan for them; that choice, and the choice of network, stays with each employee. For a South Dakota employer specifically, the most common shape we see is a company weighing "offer something for the first time" rather than "replace an existing group plan," since a South Dakota business under 50 employees is under no legal obligation to offer coverage at all; an ICHRA at any budget size is still a real, tax-advantaged benefit in that comparison, independent of whether the rate-spread math favors it.

Setting one up anyway, if it fits

South Dakota does not add state-specific ICHRA rules on top of the federal framework; the same 2019 Treasury/IRS, Department of Labor, and HHS final rule governs it here as everywhere else, and the setup sequence is the same one we walk employers through in any state where the case is real, whether that's cost arbitrage, participation flexibility, or a remote workforce:

1. Pull your census by county, not by office address. Include every remote hire, even one living out of state.
2. Check each employee's county on the savings map. A South Dakota headquarters and a Nebraska Panhandle remote hire are two different stories under the same roof.
3. Model affordability against real household incomes. The IRS's annual required contribution percentage decides whether a given employee's offer counts as affordable, which decides their premium tax credit (PTC, the ACA subsidy that lowers a Marketplace enrollee's monthly premium) eligibility. There are two accepted ways to run this test: measuring against the employee's actual household income, or using an affordability safe harbor, a simpler, IRS-approved substitute measure (an employee's Form W-2 wages, their rate of pay, or the FPL published annually by HHS) an employer can use instead of asking for real household income. Our affordability percentage guide covers the current federal threshold and each safe harbor in depth.
4. Define employee classes carefully, if you use them. 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. Eligible employees generally need written notice at least 90 calendar days before the plan year begins, with specific required content about the offer and its effect on subsidy eligibility.
6. Budget for onboarding support. Employees who have never shopped South Dakota's individual marketplace on their own need guidance, once, at enrollment.

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 U.S. county, we compare a 2026 individual-market benchmark premium (the second-lowest-cost silver plan available to a representative enrollee) against a small-group benchmark premium built from comparable small-group plan filings for that county's rate area, using Ideon data cross-verified against CMS public-use marketplace files. A county enters the qualifying dataset when the gap between those two benchmarks reaches at least $100 a month per employee. None of South Dakota's 66 counties clear that bar for 2026; the three Nebraska Panhandle counties cited above do, using the identical method. South Dakota's total county count comes from the U.S. Census Bureau's 2020 county reference file. The statewide $655 benchmark-silver figure comes from KFF's Marketplace Average Benchmark Premiums tracker, a second-lowest-cost-silver, 40-year-old measure, separate from and not part of the qualifying-county calculation itself. The 2027 rate-filing figures come from the federal Rate Review database as compiled by ACA Signups, and are requested rates, not approved ones.

Two limitations are worth stating plainly. First, benchmark premiums are built around a representative enrollee profile, so an unusually young or unusually old South Dakota workforce will see a different real-world spread than a statewide average implies. Second, rates are filed and refreshed annually, so a state that does not qualify for 2026 is not permanently excluded; we rebuild this dataset every plan year rather than reusing prior numbers, and we recommend employers do the same before every renewal.
