Surcharge & Dual Pricing Laws · South Dakota · Last verified 2026-08-27
Credit card surcharging is legal in South Dakota, but with state-specific restrictions — see the cap and disclosure rules below. Surcharges apply to credit cards only, never debit or prepaid. Dual pricing — posting a card price and a lower cash price — is legal in South Dakota.
| Credit card surcharging | LEGAL WITH RESTRICTIONS |
|---|---|
| Surcharge cap | Limited to the merchant's cost of acceptance per state consumer-protection guidance; a 4% figure appears in guidance and industry summaries but no dedicated cap statute is confirmed — this page does not state it as a statutory cap. Card-brand rules govern (lesser of 3% Visa/Discover cap or merchant's cost of acceptance; Mastercard 4% ceiling rarely operative). Debit and prepaid cards can never be surcharged. |
| Dual pricing (cash price / card price) | LEGAL |
| Governing law | No state surcharge statute — card-brand rules govern |
| Enforcement | Enforced through consumer-protection guidance rather than a dedicated surcharge statute. |

Dual pricing (posting a card price and a lower cash price) is legal.

Yes, with restrictions. Limited to the merchant's cost of acceptance per state consumer-protection guidance; a 4% figure appears in guidance and industry summaries but no dedicated cap statute is confirmed — this page does not state it as a statutory cap. Card-brand rules govern (lesser of 3% Visa/Discover cap or merchant's cost of acceptance; Mastercard 4% ceiling rarely operative). Debit and prepaid cards can never be surcharged.
Dual pricing (posting a card price and a lower cash price) is legal. Dual pricing applies to both debit and credit cards.
No. Debit and prepaid cards can never be surcharged anywhere in the U.S. — the Durbin Amendment and card-network rules prohibit it regardless of state law. Dual pricing, by contrast, lawfully covers both debit and credit.
