South Dakota sales tax at a glance
A service is taxable here unless someone exempted it
Most states list the services they tax and leave the rest alone. South Dakota reaches the sale of services as a general class and then carves out specific categories, so the default answer is yes.[1]

Estimate only. Municipal rates change only on 1 January and 1 July, and the state rate returns to 4.5% on 1 July 2027.[2] Talk to CrownGlobe about service taxability.
Rates, nexus & the 2027 reversion
South Dakota rate components
| State rate to Jun 30, 2027 | 4.2% |
| State rate from Jul 1, 2027 | 4.5% |
| Municipal general tax | Generally 1%–2% |
| Municipal gross receipts tax | 1% on four categories |
| Highest municipal rate on the current chart | 3% |
The reduction survived the 2026 legislative session unchanged, so the Department’s own guidance still states the rate returns to 4.5% on 1 July 2027.[2]
Who must register
Either trigger applies: economic nexus at more than $100,000 in gross sales into South Dakota in the previous or current calendar year, with no transaction-count test remaining, or any physical presence. Registration is due by the first day of the month starting at least 30 days after the threshold is met.[5]
A new local layer is coming: counties gained opt-in sales tax authority in the 2026 session, and the earliest a county tax can take effect is January 2027. Rate maps built now will need revising.[2]
Registering & filing
There is no sales volume threshold before a licence is needed in-state.

South Dakota sales tax FAQs
4.2% at state level, reduced from 4.5% on 1 July 2023. Municipal taxes are generally 1% to 2%, so most incorporated cities are at 6.2%, and the highest municipal rate on the current chart is 3%.
No. The reduction carries a sunset and the Department’s own guidance states the rate returns to 4.5% on 1 July 2027. It survived the 2026 legislative session untouched, so any rate table or contract straddling 30 June 2027 needs a scheduled update.
Yes, as a general class. Unlike most states, South Dakota taxes the sale of services and then exempts specific categories such as health, educational, social and agricultural services. The default answer for an unlisted service is taxable.
Yes, at the full combined rate. There is no general grocery exemption and no reduced food rate. Purchases made with SNAP benefits are the only food-related exclusion.
More than $100,000 in gross sales into the state in the previous or current calendar year. The 200-transaction test that this state’s own litigation once validated no longer appears in current Department guidance.
A separate 1% city levy on alcoholic beverages, eating establishments, lodging of under 28 consecutive days and admissions to amusement, athletic and cultural events. It stacks on the general municipal rate, so hospitality receipts in a 2% city carry 7.2% while ordinary retail carries 6.2%.
