Kansas credit card surcharge law lets a business pass card processing costs to customers, but only if the surcharge is disclosed clearly before the sale. The governing statute, K.S.A. 16a-2-403, requires a “clear and conspicuous notice” of the surcharge amount at the point of entry or point of sale, before the transaction is completed.1Kansas State Legislature. Kansas Code 16a-2-403 – Surcharge on Credit or Debit Cards; When Permitted State law sets no percentage cap. The caps you’ve heard about come from Visa and Mastercard, and they apply regardless of what Kansas says.
What the Kansas Statute Actually Requires
K.S.A. 16a-2-403 is a one-sentence rule in practice. A seller or lessor cannot impose a surcharge on a credit card customer unless the business gives clear and conspicuous notice of the surcharge amount at the point of entry or point of sale, before the transaction closes.
That is the full state obligation. The statute does not cap the surcharge at any percentage. It does not require that the surcharge match the merchant’s actual processing cost. It does not require uniform treatment across card brands. Merchants who assume a 4% ceiling, or a 3% ceiling, is Kansas law are confusing network rules with state statute.
One important limit lives inside the statute itself: it covers credit cards. Debit card surcharges are a separate matter governed by federal law, and the answer there is no.
How to Disclose the Surcharge
“Clear and conspicuous” at the “point of entry or point of sale” gives you flexibility, but the practical bar is simple. A customer should never see the surcharge for the first time on the receipt.
For a brick-and-mortar store, that means signage at the entrance and at the register stating the surcharge amount or percentage. For an online business, it means displaying the surcharge on the checkout page before the customer submits payment. Verbal disclosure by a cashier is not prohibited by the statute, but it leaves no paper trail and invites disputes. Signage and on-screen notices are far more defensible if a customer later claims they were not told.
Card networks add a receipt-level disclosure on top of state law. Visa requires the surcharge to appear on every transaction receipt as a separate line item, distinct from the purchase price.2Visa. Surcharging Credit Cards – Q&A for Merchants That rule applies to in-person and online transactions alike.
The Card Network Cap and 30-Day Notice
Kansas law is only half of compliance. Visa and Mastercard impose their own surcharge framework, and a merchant who satisfies the statute but violates network rules can be fined by their processor or lose their merchant account.
As of April 2023, both Visa and Mastercard capped surcharges at 3% of the transaction amount. The surcharge also cannot exceed the merchant’s actual cost of accepting credit cards, whichever is lower. If your effective processing rate is 2.5%, your ceiling is 2.5%, not 3%.
Before you turn surcharging on, you have to notify your acquiring bank, the bank that processes your card transactions, at least 30 days in advance.3Visa. Merchant Surcharging Considerations and Requirements Direct notice to Visa is no longer required; the acquirer notification covers it. The surcharge amount also has to be transmitted in a dedicated data field in the authorization message sent to the card network, which is a point-of-sale configuration issue your processor can walk you through.
Two other network constraints matter. Surcharges can only be applied to credit cards, never to prepaid or debit cards, even when a debit card is run as credit. And if you operate in other states, check their rules separately: several states still prohibit surcharging outright.
Debit Cards Are Off-Limits Under Federal Law
Debit card surcharges are prohibited nationwide under the Durbin Amendment provisions of the Dodd-Frank Act.4Office of the Law Revision Counsel. 15 U.S. Code 1693o-2 – Reasonable Fees and Rules for Payment Card Transactions This catches merchants off guard because a customer who swipes a debit card and selects “credit” at the terminal is still using a debit card. Surcharging that transaction violates federal law no matter how the terminal routes it. If you surcharge, configure your point-of-sale system to recognize debit cards and exempt them automatically.
Cash Discounts as an Alternative
Some Kansas businesses sidestep surcharge compliance by offering a cash discount instead. A surcharge adds a fee for using a credit card; a cash discount reduces the price for paying with cash or check. The customer’s out-of-pocket cost can be identical, but the legal frameworks are different.
Federal law explicitly protects cash discounts. Under 15 U.S.C. ยง 1666f, card issuers cannot prohibit sellers from offering discounts to customers who pay by cash, check, or similar means. The discount must be available to all buyers, and its availability has to be disclosed clearly and conspicuously.5Office of the Law Revision Counsel. 15 U.S. Code 1666f – Inducements to Cardholders by Sellers of Cash Discounts
The structural difference is what matters for compliance. A cash discount program sets the card price as the regular posted price and advertises a lower price for cash. A surcharge program sets the cash price as the base and adds a fee for card users. Advertising the cash price as the regular price and then adding a fee at the register is a surcharge wearing a discount label, and that framing invites enforcement attention.
What a Violation Costs
Surcharge violations are enforced through the Kansas Consumer Protection Act (K.S.A. 50-623 et seq.).
Under K.S.A. 50-636, a violation can draw a civil penalty of up to $10,000, recoverable in an action brought by the Attorney General, a county attorney, or a district attorney. A continuing violation not tied to a specific consumer transaction counts as a separate violation for each day it continues. Willful violation of a court order under the Act raises the penalty to $20,000.6Justia Law. Kansas Code 50-636 – Civil Penalties
Consumers can also sue on their own. Under K.S.A. 50-634, an individual customer harmed by a violation can seek a declaratory judgment, an injunction, or damages, and the court may award reasonable attorney fees to a prevailing consumer.7Kansas Office of Revisor of Statutes. Kansas Code 50-634 That fee-shifting provision is the one to watch. It means a small surcharge dispute can become expensive quickly if a court finds a violation.
Separately, card networks can fine your processor, require audits, or terminate your merchant account for network rule violations, independent of anything the state does.
Compliance Checklist
A compliant program satisfies state law and card network rules at the same time. The state side is simple; the network side is where small businesses tend to slip.
- Notify your acquiring bank at least 30 days before you start surcharging.
- Post signage at your entrance and register stating the surcharge amount or percentage. Online, display it on the checkout page before the customer confirms payment.
- Cap the surcharge at 3% or your actual effective processing cost, whichever is lower.
- Show the surcharge on every receipt as a separate line item, distinct from the purchase price.
- Exclude debit cards, including debit cards processed through credit networks, by configuring your terminal to identify them.
- Make sure your payment system transmits the surcharge amount in the dedicated authorization data field required by the card network.
The two steps merchants most often miss are the 30-day acquirer notification and the terminal configuration that distinguishes debit from credit. Posting a sign and switching on a surcharge the next day puts you out of compliance with network rules from day one, even if the Kansas statute is satisfied. Build the lead time into your rollout and ask your processor to confirm the terminal is set up correctly before the first transaction.
