Credit Card Surcharging Rules in 2026: What Every Merchant Needs to Know

Credit card surcharging — the practice of adding a fee to transactions paid with a credit card — has become one of the most searched topics among merchants looking to offset their processing costs. The legal landscape has evolved significantly over the past few years, and 2026 brings new considerations that every business owner needs to understand before implementing a surcharge program.

The ability for merchants to surcharge credit card transactions stems from the landmark 2013 settlement in the class action lawsuit against Visa and Mastercard. Before that settlement, card network rules explicitly prohibited merchants from passing processing costs to customers. The settlement changed that, but it did not create a free-for-all. There are federal guidelines, state laws, and card network rules that all must be followed — and getting any of them wrong can result in significant fines.

Let us start with the basics. A surcharge is an additional fee added to a transaction when a customer pays with a credit card. It is meant to offset the merchant's cost of accepting that card. Surcharges can only be applied to credit card transactions — never to debit card transactions, even if the debit card is run as credit. This is a critical distinction that many merchants get wrong, and it is one of the fastest ways to draw a compliance violation.

As of 2026, credit card surcharging is prohibited outright in several states: Connecticut, Massachusetts, and California all ban credit card surcharges. Puerto Rico also prohibits surcharging under its own regulations. If your business operates in any of these jurisdictions, you cannot surcharge credit card transactions under any circumstances. California's ban is particularly significant given the size of its economy and the number of merchants operating there. Violations can result in state attorney general action, fines, and forced refunds to affected customers.

Colorado allows surcharging but caps the amount at 2 percent, which is lower than the card network maximums. Oklahoma enacted new surcharging regulations in 2025 that require enhanced disclosure and limit the surcharge to the merchant's actual cost of acceptance — you cannot surcharge more than what you are actually paying to process the transaction. Several other states have introduced bills to regulate or ban surcharging, so the legal landscape continues to shift.

Even in states where surcharging is legal, the card networks impose their own rules and caps. Visa caps surcharges at 3 percent of the transaction amount. Mastercard allows up to 4 percent. However, in both cases, the surcharge cannot exceed the merchant's actual cost of accepting the card. If your effective processing rate is 2.5 percent, you cannot surcharge 3 percent — even though Visa's cap would technically allow it. The surcharge must reflect your real cost.

Disclosure requirements are strict and non-negotiable. If you surcharge, you must display clear signage at the entrance to your business, at the point of sale, and on your website (for e-commerce transactions). The signage must state that a surcharge is applied to credit card transactions and specify the exact percentage. On receipts, the surcharge must appear as a separate line item — it cannot be bundled into the transaction total without disclosure.

For e-commerce merchants, the surcharge must be clearly disclosed before the customer enters their payment information. It should be visible on the checkout page, not buried in terms and conditions. The card networks specifically look for online merchants who fail to disclose surcharges properly, and violations can result in fines ranging from $25,000 to $100,000 per incident from Visa alone.

Before implementing a surcharge program, merchants must notify the card networks. Visa requires 30 days advance written notice before you begin surcharging. Mastercard has a similar notification requirement. Your payment processor typically handles this notification on your behalf, but it is your responsibility to ensure it is completed. Processing surcharges without proper notification is a violation regardless of state law.

The penalties for surcharging violations are severe. Card network fines can range from $25,000 to over $1,000,000 depending on the severity and duration of the violation. State-level penalties vary but can include per-transaction fines, mandatory refunds, and even loss of the ability to accept card payments. In the worst cases, merchants have been placed on the MATCH list (Member Alert to Control High-risk merchants), which effectively blacklists them from obtaining a merchant account with any processor for five years.

Beyond the legal and compliance risks, surcharging has practical downsides. Customer satisfaction surveys consistently show that consumers view surcharges negatively. A 2025 study by the National Retail Federation found that 68 percent of consumers would consider taking their business elsewhere if a merchant surcharges credit card transactions. For businesses in competitive markets, the customer goodwill cost of surcharging may outweigh the processing fee savings.

This is where dual pricing — also known as cash discounting — offers a compelling alternative. Instead of adding a fee for credit card use, dual pricing displays two prices: a lower cash price and a standard card price. The psychology is different — customers perceive a discount for paying cash rather than a penalty for using their card. And critically, cash discounting is legal in all 50 states with no exceptions.

Dual pricing programs do not require card network notification, are not subject to the same percentage caps, and carry significantly less compliance risk than surcharging. The key requirement is proper signage and receipt formatting, which Optec handles as part of our dual pricing setup. Learn more about how our dual pricing program works at /solutions/dual-pricing. We configure your terminals, print compliant signage, format receipts correctly, train your staff, and monitor the program monthly to ensure ongoing compliance.

For merchants who want to offset their processing costs, the choice between surcharging and dual pricing comes down to risk tolerance and customer experience. Surcharging is legal in most states but comes with a complex web of rules, notification requirements, and penalties. Dual pricing achieves the same economic outcome with less risk, better customer perception, and nationwide legality.

It is also worth understanding how surcharging interacts with different payment types. Prepaid cards occupy a gray area — some are considered debit products and cannot be surcharged, while others may technically be credit products. The safest approach is to never surcharge prepaid cards. Business credit cards and corporate cards can be surcharged, but be aware that your B2B customers may push back harder on surcharges than consumers, especially if they have alternative vendors who do not surcharge.

For multi-location businesses, surcharging compliance becomes even more complex. If you operate in multiple states, you may need different surcharging policies for each location. A restaurant chain with locations in Texas and Connecticut, for example, can surcharge in Texas but not in Connecticut. Your POS system needs to be configured differently for each jurisdiction, and your staff needs to be trained on the specific rules for their location. This operational complexity is another reason many multi-location businesses prefer dual pricing, which works identically in every state.

Online businesses face unique surcharging challenges as well. When an e-commerce merchant sells to customers across multiple states, the surcharging rules of the customer's state apply — not the merchant's state. If you are based in Florida where surcharging is legal, but you sell to a customer in Massachusetts where it is banned, you cannot surcharge that transaction. Implementing state-specific surcharging logic in your e-commerce checkout adds development cost and ongoing maintenance that many businesses find difficult to justify.

If you are considering either approach, the first step is understanding your actual processing costs. Many merchants do not know their effective rate — the total percentage they pay on each dollar processed after all fees are included. Without that number, you cannot set a compliant surcharge or an appropriate dual pricing spread.
