Full transcript
Overview
South Dakota sales tax is easier to follow when the main rules are explained clearly. Here's a quick breakdown of the basics.
Who administers it
South Dakota sales tax is administered by the South Dakota Department of Revenue.
State and local rates
The WGA page lists South Dakota's statewide base sales tax rate as 4.2%. Local rates can stack on top and are generally based on the delivery address.
Economic nexus
In simple terms, nexus means a business may have enough connection to the state for its sales tax responsibilities to need review. For remote sellers, the WGA page lists South Dakota's economic nexus threshold as $100,000 in sales.
Filing frequency
The WGA page notes that South Dakota filing is monthly by default. The bookkeeping goal is to keep collected tax aligned with the filing schedule that applies.
What to watch for
One South Dakota watch-out: the state whose law produced the Wayfair decision. Most services are taxable, which is broader than most states.
