How Sales Tax Works in South Dakota

City taxes: Cities in South Dakota may impose their own sales tax, adding further variability to combined rates.
Rates in South Dakota are typically updated quarterly. Businesses should monitor rate changes regularly to maintain compliance.
Why Rates Vary by County in South Dakota
The combined sales tax rate a customer pays in South Dakota depends on the specific jurisdiction of the transaction. Local governments use sales tax revenue to fund essential services such as infrastructure, public safety, and education.
This means that two addresses within the same city may have different tax rates if they fall in different special taxing districts. ZIP codes are particularly unreliable for tax determination because a single ZIP code can span multiple counties or tax jurisdictions.
For businesses operating in South Dakota, manually tracking these rate changes across every jurisdiction is impractical. An automated API solution ensures you always apply the correct rate at the point of sale, reducing compliance risk and audit exposure.
