A 40-year-old accountant 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 cheapest Silver at age 27, South Dakota ranks 5 of 15 for this occupation.
Desk work usually means low claim volume, and low claim volume changes the math: a high-deductible plan paired with an HSA lets you fund the deductible with pre-tax dollars and keep whatever you do not spend. In most years that beats paying a Silver premium for benefits you never touch.
Occupational context: Sedentary strain: eye strain, repetitive stress, and Q1 stress load.
Two things get confused here constantly. Risk exposure decides what coverage you should buy. It does not decide what you are charged — South Dakota carriers rate on age, ZIP, tobacco and family size, full stop. A accountant with a bad back and a healthy 40-year-old office worker in the same county see the same number.
Premium is set by rating area, so a accountant 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 |
|---|---|---|---|---|
| Hand | $702 | Avera | $6,000 | 2 |
| Stanley | $702 | Avera | $6,000 | 2 |
| Haakon | $761 | Wellmark of South Dakota | $5,000 | 3 |
| Oglala Lakota | $761 | Wellmark of South Dakota | $5,000 | 3 |
| Minnehaha | $512 | Avera | $6,000 | 2 |
| Hutchinson | $532 | Avera | $6,000 | 2 |
The spread across just these six is $249/month — $2,989 a year for the same metal tier. Statewide the range runs $512 to $882. Coverage by County publishes all 66 South Dakota counties individually.

Cross-state numbers are useful for understanding whether South Dakota is treating you well, not for arbitrage. You cannot buy an out-of-state exchange plan. If you are a accountant weighing a relocation for other reasons, the premium difference is a real line item worth putting in the decision.
Deduction categories that generally fit this trade: Software, licensing, CPE credits, home office. Note the ordering problem with health premiums: the §162(l) deduction lowers your AGI, and your AGI is what sets your premium tax credit, so the two calculate against each other. That is a CPA conversation and worth having before you enroll, not after.
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.
