South Dakota's threshold, in its own words
SD DOR: more than $100,000 in gross sales into the area in the previous or current calendar year (marketplace provider bulletin, July 2025). Effective July 1, 2023 (SB30) the 200-transaction threshold was removed. State rate reduced from 4.5% to 4.2% effective July 1, 2023 (HB1137); the DOR notes the reduction is repealed (sunsets) effective June 30, 2027.
The area has a marketplace facilitator law, so sales through a marketplace that collects for you are handled by the marketplace.
