South Dakota Credit Card Surcharge Law
South Dakota credit card surcharge law allows surcharging, and unlike several neighboring states, no South Dakota statute puts a number on it or spells out how to disclose it. The card network rules do the real work here, and the South Dakota Attorney General's Division of Consumer Protection publishes consumer education that echoes those same rules. This page covers what the networks require, what the state's own guidance says, and what a dealership needs to get right at the counter.
South Dakota Allows Surcharging, With No State Cap
No statute, no cap, no state disclosure rule. Just the network rules and one state office describing them.
As of July 2026, South Dakota allows credit card surcharging, and it does so with no statute standing behind or against it. Its credit card chapter and its consumer protection title carry no surcharge provision at all, no ban, no cap, no disclosure requirement. The rules that actually bind a South Dakota dealership are the card network rules, the same ones that apply everywhere else in the country. The state's own consumer office publishes guidance that echoes those network rules, but it is education, not law.
| Question | Answer |
|---|---|
| Status | Allowed |
| Cap | Card network rules, no state statute |
| Disclosure | No state statute; card network rules apply (state consumer guidance echoes them) |
| Debit | Never surcharged (card network rule) |
That verdict puts South Dakota among the 47 states where surcharging is legal today. The state by state picture, all 50 rows of it, lives in our credit card surcharge laws by state guide.
Card Network Rules Govern
With no South Dakota statute in the picture, the network ceilings are the whole story.
-
Visa: 3% Cap
In force nationwide since April 2023, and no South Dakota rule reaches down to lower it.
-
Mastercard: 4% Cap
Mastercard runs its own program, with a higher ceiling than Visa's.
-
Debit Never Surcharges
No debit, prepaid, or gift card can carry a surcharge, here or in any other state.
-
Disclosure Is Mandatory
The receipt needs its own surcharge line, and notice has to be up at the door and the counter before the card is ever run.
There Is No Federal Surcharge Cap
A number of guides tell merchants a federal law caps surcharges at 4 percent. That is not true. No federal statute sets any surcharge ceiling at all. The two numbers that matter come from the card networks, not Congress: Visa at 3 percent, Mastercard at 4 percent. The Durbin Amendment is the one federal law anywhere near this topic, and it deals with debit interchange, which is exactly why debit can never carry a surcharge in the first place.
What South Dakota's Consumer Office Publishes
Not a law on the books, just the state's own office describing the network rules already in force.
As of July 2026, South Dakota has no surcharge statute, so the clearest state-level word on surcharging comes from the South Dakota Attorney General's Division of Consumer Protection. Its consumer education "Fast Facts" material includes a page on credit cards that describes how a surcharge is supposed to work.
The page says a surcharge should not exceed what the merchant actually pays to accept the card. It applies to credit card transactions only, never to debit or prepaid cards. And the page says any surcharge has to be disclosed clearly, with notice posted at the store entrance and again at the point of sale, or on the home page for an online store, and the dollar amount shown on the receipt.
Guidance, Not a Statute
This is consumer education, not a law. South Dakota has no statute that caps a credit card surcharge or sets a disclosure requirement, and this page does not create one. It is the state consumer office describing the same card network rules every merchant already follows. The binding limits are the network rules above.
What This Means at the Counter
The counter needs a few things right, and none of them require a lawyer on standby.
Dealerships are all we do, and that focus earns its keep in a state like South Dakota, where the rules are easy to overthink. We track the state, not your front desk. South Dakota lays no cap or disclosure rule of its own over the network rules, so the counter has one job instead of two: run the network rules right, and the state picture takes care of itself. The program's standing practice already posts signage at the door and again at the point of sale, and itemizes the surcharge as its own line on every receipt.

Straight Answers on South Dakota Rules
Yes. As of July 2026, no South Dakota statute bans credit card surcharges. Card network rules govern, and the state's consumer protection division publishes consumer guidance that echoes them.
There is no state cap. The card network ceilings apply, Visa at 3 percent and Mastercard at 4 percent, and a surcharge should never exceed what it costs the dealership to accept the card. Where your own program rate lands under those ceilings is a demo conversation, not something a page like this can pin down.
No. There is no federal surcharge cap anywhere in the law. Visa and Mastercard set the only ceilings that matter, 3 percent and 4 percent, and they set them on their own. The lone federal statute in this territory is the Durbin Amendment, which deals with debit and has nothing to do with credit surcharges.
Never. A debit, prepaid, or gift card cannot carry a surcharge anywhere in the country, and no state, South Dakota included, can opt out of that network rule.
No. South Dakota has no surcharge statute. The clearest state-level word is consumer education from the Attorney General's consumer protection division, which describes the card network rules rather than creating a state law of its own.
