What South Dakota merchants need to know
South Dakota is grouped with New Jersey, Nevada, and Nebraska as an actual-cost-only surcharge state: whatever you charge for card payment can't exceed what the card genuinely costs you to accept, regardless of the card networks' 3% maximum. For a state with a large agricultural and rural retail economy, that distinction matters more than it might elsewhere — many South Dakota merchants have card mixes and ticket sizes different enough from the national average that a generic 3% surcharge is unlikely to match their actual cost precisely.
The practical takeaway for South Dakota merchants: know your actual effective rate before setting a surcharge percentage, rather than defaulting to the network maximum. That's the number the law actually cares about here.
The cash discount alternative
Wherever surcharge rules get complicated, dual pricing doesn't: posting a card price and offering a discount for cash is legal in all 50 states when it's structured correctly — the posted price must be the card price, with cash receiving a true discount. The economics match a surcharge; the compliance profile usually beats it.
South Dakota's actual-cost requirement is one more reason cash discount programs appeal to merchants who'd rather not recalculate their surcharge every time their card mix shifts.
