A 40-year-old plumber in South Dakota pays a median $725/month for a Silver plan before subsidies — 7th of 15 on cost. The cheapest plan in the state is $512 from Avera in Lincoln. On highest out-of-pocket maximum, South Dakota ranks 12 of 15 for this occupation.
Trade work concentrates cost into rare, expensive events rather than spreading it across the year. That inverts the usual shopping logic: a lower premium with a $9,200 ceiling is a worse deal than a higher premium with a $6,000 one, because the ceiling is what you actually hit. These rankings follow the ceiling.
Occupational context: Confined-space entry; sewage and biohazard exposure; back strain.
Worth being clear about what this does and does not affect: a carrier in South Dakota cannot ask what you do for a living, cannot charge a plumber more than a librarian of the same age in the same ZIP, and cannot exclude anything you were already treated for. Occupation only tells you which plan structure to shop for.
Premium is set by rating area, so a plumber in one South Dakota county can pay materially more than one an hour away. Six counties from across the state, cheapest Silver plan for a 40-year-old:
| County | Cheapest Silver @40 | Issuer | Deductible | Carriers |
|---|---|---|---|---|
| Brule | $702 | Avera | $6,000 | 2 |
| Hyde | $702 | Avera | $6,000 | 2 |
| Tripp | $702 | Avera | $6,000 | 2 |
| Jackson | $761 | Wellmark of South Dakota | $5,000 | 3 |
| Perkins | $761 | Wellmark of South Dakota | $5,000 | 3 |
| Turner | $516 | Sanford | $6,000 | 3 |
The spread across just these six is $245/month — $2,941 a year for the same metal tier. Statewide the range runs $512 to $882. Coverage by County publishes all 66 South Dakota counties individually.

For a plumber, the gap between $7,200 and $10,600 in annual out-of-pocket maximum is worth more than any premium difference on this page. One serious injury reaches that ceiling regardless of which plan you picked.

A caveat on the table above: rating is by residence, not by job site. A plumber living in South Dakota and working across a state line still buys South Dakota plans. A genuine permanent move does trigger a special enrollment period, but the plan year restarts with a fresh deductible.
If you file a Schedule C as a plumber, the categories that usually show up are: Tools, van, licensing, materials, liability insurance. The health premium itself is normally an above-the-line deduction under IRC §162(l), which reduces AGI rather than requiring you to itemize. Your CPA should confirm it against your actual situation.
If your household income is above the subsidy range, ACA is not automatically the answer. There are other categories of coverage that may fit, and they work very differently. That is a conversation, not a web page.
The cheapest Silver plan for a 40-year-old in South Dakota is $512 per month from Avera, with a state median of $725. Both figures are full price before premium tax credits; most buyers pay less after subsidies.
No. Under the ACA, carriers cannot rate, decline, or exclude based on occupation or health history. Rates vary only by age, ZIP code, tobacco use and household size.
Yes. Plan types filed for 2026: EPO, HMO, PPO.
South Dakota ranks 7 of 15 states covered here, at a median $725 per month. Indiana is cheapest at $558 and Nebraska is most expensive at $875.
Below the cliff. At this income a single-person household remains eligible for a premium tax credit in 2026.
This occupation sits above the cliff in 8 of the 21 states reported and below it in the other 13, so the answer changes with the state.
What this figure is. It is the median annual wage BLS reports for Plumbers, Pipefitters, and Steamfitters (SOC 47-2152) in South Dakota. BLS surveys wage and salary workers and excludes the self-employed, so it is a benchmark for the occupation in this state — not the income of a self-employed plumber. Premium tax credit eligibility is set by household modified adjusted gross income and household size, not by occupation, so treat this as a reference point rather than a determination of what you qualify for.
Why the cliff is back. The enhanced premium tax credits expired on 31 December 2025. For plan year 2026 the 400% FPL limit applies again, so household income above $62,600 ends premium tax credit eligibility outright.
This page compares states. For South Dakota specifically — county-by-county carriers, plan data and enrollment help — I publish that on Coverage by County, including a page written for Plumbers in South Dakota and a blog covering deductibles, subsidies and special enrollment.
Right now 3 carriers file plans across the 66 counties of South Dakota. Participation is reset annually, which is why Plumbers should check the roster in November rather than assume this year’s options carry over.
Rate filings for 2027 point to roughly a 15% median increase nationally, from −1% at one end to 54% at the other. South Dakota has not finalised, so treat exact local 2027 pricing as unavailable rather than unknown.
Mark November 1, 2026 to open and December 15 to act. That second date guarantees cover from January 1 in South Dakota regardless of how the current litigation over the enrollment window resolves.
In your favour: PPOs are sold in all 66 South Dakota counties. That is the type most likely to pay toward out-of-network care, and worth defending at renewal if your work as a plumber takes you around.
Nothing about 2027 is urgent yet, which is exactly why it is worth ten minutes now. Come November you will be choosing between South Dakota’s carriers under a deadline; today you can do it without one.
Give me a ZIP and I will tell you three things:
There is no single South Dakota price. Enter your ZIP and I will pull what is filed in your county, then work out what help you qualify for.
