South Dakota tax guide: sales, income and property tax
Three taxes decide most everyday money calculations in South Dakota: what you pay at the register, what leaves your paycheck, and what your home costs each year. This guide sets out each one with the current figures, then links to the calculators that apply them. Rates are reviewed against state sources; confirm a specific transaction with the South Dakota Department of Revenue.
The short answer
South Dakota: 4.2% state sales tax, about 6.4% average combined (rank 32 of 51 — 0.21 points below the 6.61% all-state average), no state income tax, and an average effective property tax of 1.09% (rank 19 of 51). On a $100 purchase at the average combined rate, the tax is $6.
Sales tax in South Dakota
The statewide base rate is 4.2%. Counties, cities and special districts add their own layers, bringing the average combined rate to about 6.4% — and the rate at a specific address can sit well above or below that average. On a $100 purchase, the tax is $4 at the base rate and roughly $6 at the average combined rate. The difference is local tax, which is why two towns in the same state can charge noticeably different totals on the same item.
Groceries are taxed at the full sales tax rate. South Dakota taxes groceries at the full rate.
Worked examples at the average combined rate
What the 6.4% average combined rate adds to purchases of different sizes:
| Purchase | Tax | Total |
|---|---|---|
| $25 | $2 | $27 |
| $100 | $6 | $106 |
| $500 | $32 | $532 |
| $1,000 | $64 | $1,064 |
| $10,000 | $640 | $10,640 |
If you sell into South Dakota from another state, economic nexus rules can oblige you to collect its tax once your sales pass the state's threshold — the exact threshold and what counts toward it are in the South Dakota sales tax calculator and rate page, and the data hub for the state is the South Dakota locations page.
Income tax in South Dakota
South Dakota levies no state income tax on wages. That raises take-home pay compared with an identical salary in a taxing state, but the revenue shows up elsewhere — in South Dakota that usually means some mix of sales and property taxes, which is why the three taxes on this page should be read together.
Federal tax applies the same everywhere; the state layer is what changes a paycheck between two states. Run the same salary through the paycheck calculator and the take-home pay calculator with and without a state rate to see the size of the difference before negotiating a move or a remote-work arrangement.
Property tax in South Dakota
The average effective property tax rate in South Dakota is about 1.09% of a home's value per year. On a $400,000 home that is roughly $4,360 a year, or $363 a month — a real line in the housing budget, collected through escrow in most mortgages. Averages hide wide local variation: the county and school district set most of the rate, and homestead exemptions can cut the taxable value for owner-occupiers.

What this means for your money
South Dakota does not tax wages, but the revenue is recovered elsewhere. Property tax is the main lever: at an average effective rate of 1.09% (rank 19 of 51, against an all-state average of 1.04%), a $400,000 home carries about $4,360 a year — collected monthly through mortgage escrow, so it shows up as a higher monthly payment rather than an annual bill. Renters feel it indirectly through rent.
Read together: South Dakota combines an average combined sales tax of 6.4% (rank 32 of 51), an average effective property tax of 1.09% (rank 19 of 51) and no state tax on wages. A household comparing states should compare all three against its own pattern — a high earner who rents weighs the income tax most; a homeowner on a fixed income weighs the property tax most.
