About ZIP 57105
ZIP boundaries are postal routes, not tax boundaries.
South Dakota temporarily cut its state rate from 4.5% to 4.2% through 2027, so Sioux Falls totals are lower than older tables show. For destination-based sourcing, South Dakota sellers should confirm the rate by full street address rather than ZIP alone — a single ZIP can cross a city limit or a transit-district boundary, and the rate follows the boundary, not the mail route.
