Surcharging vs. Convenience Fees vs. Dual Pricing 2026

Merchant discount rate fees, the combined cost of interchange, assessment, and processor markup, hit $187 billion in the United States in 2024. Rewards cards, commercial cards, and card-not-present transactions have pushed average processing costs up steadily for more than a decade.

Merchants have responded. In 2019, only about 1 to 2 percent of U.S. small businesses added any kind of surcharge to card transactions. By 2024, a J.D. Power survey of nearly 3,841 small businesses found that number had climbed to 34 percent. More than a third of American small businesses now pass some or all of their card costs to customers, mostly because the math stopped working any other way.

That shift raises three real questions for any organization that accepts cards. Which fee model is legal where you operate? Which one will card networks actually allow? And which one will customers accept without walking away? This guide answers all three.

The Four Models: What Each One Actually Is

There are four distinct mechanisms for passing card costs to customers, and they are not interchangeable. Under card network rules, each one triggers different obligations, applies to different card types, and carries different legal exposure depending on where you operate.

Surcharging

A surcharge is an additional fee added to the transaction total when a customer uses a credit card. It is triggered by the payment method, not the payment channel. Merchants gained explicit legal authorization to surcharge in the U.S. through a 2013 court-sanctioned settlement that ended card network rules previously prohibiting checkout fees entirely.

The surcharge cannot exceed the merchant's actual cost of acceptance or the applicable network cap, whichever is lower. Visa's cap dropped from 4 percent to 3 percent in April 2023 and remains at 3 percent in 2026. Mastercard follows the same practical 3 percent ceiling when a merchant accepts both networks. The surcharge can never be applied to debit cards, prepaid cards, or PIN based debit transactions, even when those cards carry a Visa or Mastercard logo.

One detail trips up a lot of merchants, including some payment software providers. The surcharge has to reflect the actual merchant discount rate for each specific card product, not a flat rate applied to every credit card. A Visa Signature Preferred card carries a higher interchange rate than a basic Visa CPS Retail card. Charging a flat 3 percent on every card, when some cards actually cost the merchant only 1.65 percent plus $0.10, technically exceeds cost and violates network rules.

Dual Pricing

Dual pricing, often called a cash discount program, is architecturally different from surcharging, even though both end with card customers paying more than cash customers.

In a dual pricing model, the price displayed on the shelf, menu, website, or terminal is the card price. It already builds in processing cost. Cash customers get a discount from that displayed price at checkout. Under the Durbin Amendment framework, dual pricing treats the posted price as the highest price, and cash customers get a reduction from it. Surcharging treats the posted price as the base price, and card customers pay an addition on top.

That distinction is what allows dual pricing to work legally in all 50 states while surcharging faces restrictions in several. Dual pricing also applies to all card types, including debit cards run as credit, because no fee is technically ever added. A discount is simply removed.

Convenience Fees

A convenience fee is triggered by the payment channel, not the payment method. It compensates for the cost of offering a payment option outside the merchant's normal way of doing business, for example an online portal when in-person payment at a counter is the standard.

Visa requires that a convenience fee represent a bona fide convenience to the cardholder, meaning an alternative standard payment method has to actually exist. A business that only accepts cards online, with no other option available, generally cannot call that fee a convenience fee. Visa also requires the fee to be a fixed flat amount, not a percentage. Mastercard takes a broader view and permits convenience fees for any alternative channel without Visa's strict bona fide convenience requirement for most merchant categories.

Service Fees

Service fees are the most overlooked category, and the most relevant one for government agencies, municipalities, school districts, utilities, and higher education.

Visa defines the service fee as a fee assessed by eligible merchant category codes in card-present or card-absent environments, applicable to Visa consumer debit, consumer credit, and commercial cards. Unlike a convenience fee, it does not require an alternative channel. Unlike a surcharge, it can be applied to debit cards. It has to be processed as a separate transaction and disclosed clearly in advance.

In October 2025, Visa expanded its Service Fee program to include utility merchants under MCC 4900. Before that, utility service fees had been limited to government and education MCCs. Visa also eliminated the prior merchant registration requirement and the need to send a Merchant Verification Value, giving utility providers a lot more flexibility. For government and municipal payment programs, the service fee, not the convenience fee and not the surcharge, is the correct technical category.

Quick Comparison

The Legal Map in 2026

Surcharging: Legal in Most States, With Real Asterisks

Connecticut and Massachusetts remain the only two states with firm, active statutes prohibiting merchant-level credit card surcharging. Violations can carry civil penalties of $500 per violation, and card networks can revoke card acceptance privileges entirely. Kansas officially lifted its surcharge ban effective January 1, 2025, continuing the national trend toward legalization.

Several states permit surcharging but add rules beyond card network requirements:

California. Surcharging is legal following Italian Colors v. Becerra in 2018. California's SB 478, the Honest Pricing Law, fully in effect since 2024, requires that any mandatory fee be built into the advertised price.

New York. Under NY General Business Law Section 518, sellers must clearly post the total credit card price, inclusive of the surcharge. A warning sign near the register is not enough.

Colorado. HB21-1289 caps surcharges at 2 percent or actual processing cost, whichever is lower, tighter than the 3 percent network cap.

Minnesota. Effective January 1, 2025, mandatory unavoidable fees must be included in the advertised price, similar to California's approach.

The FTC's Rule on Unfair or Deceptive Fees took effect May 12, 2025, adding federal disclosure requirements currently targeting short-term lodging and live event ticketing. For covered sectors, unavoidable surcharges where no alternative payment method exists must be included in the advertised price.

Dual Pricing: Legal Everywhere

Dual pricing is legal in all 50 states. The Durbin Amendment, part of Dodd-Frank in 2010, explicitly protects a merchant's right to offer a cash discount in every state, regardless of card network preference. Networks cannot contractually prohibit it.

Understanding What You Are Actually Passing Through

Interchange, the fee collected by the card-issuing bank, is set by the networks, not your processor, and it is non-negotiable. Representative 2026 card-present credit interchange rates:

Your merchant discount rate, the number that sets your maximum allowable surcharge, is interchange plus assessment fees plus your processor's markup. The regulated debit interchange cap under Durbin is $0.21 plus 0.05 percent of the transaction, which is exactly why debit surcharging is both prohibited and unnecessary.
