Can You Charge a Credit Card Convenience Fee? Limits and Disclosure

You can charge a credit card convenience fee in most states, but only if the fee fits the narrow definition of a convenience fee, your state permits it, and you follow the card networks’ rules on amount, disclosure, and setup. Get the category wrong or skip the notification steps, and what you called a convenience fee becomes an illegal surcharge in the eyes of Visa, Mastercard, or your state attorney general.

The first thing to sort out is what kind of fee you actually want to charge, because “convenience fee” and “surcharge” are not interchangeable terms.

Convenience Fee vs. Surcharge

A convenience fee is a flat charge for letting a customer pay through a channel that isn’t your normal way of doing business. If you usually take payment in person and a customer asks to pay by phone or online, that alternate channel is what justifies the fee. A surcharge is a percentage added to a transaction specifically because the customer used a credit card instead of cash or debit.

The rules governing each are completely different. Surcharges are tied to the card type. Convenience fees are tied to the payment channel. A brick-and-mortar store that adds a “convenience fee” to every in-store credit card transaction is really imposing a surcharge under a friendlier name, and the card networks treat that as a violation. An online-only business cannot charge a convenience fee for online payments either, because online is the standard channel, not an alternative to it.

One rule applies across every network: you cannot stack a convenience fee and a surcharge on the same transaction. It’s one or the other.

When You Cannot Charge the Fee at All

Two situations shut the door regardless of how carefully you set up the program.

The first is debit cards. Federal law prohibits surcharging debit card transactions nationwide, whether the transaction runs as PIN or signature. The prohibition comes from the Durbin Amendment, codified at 15 U.S.C. § 1693o-2.¹ A business that surcharges a debit card is violating federal law even if credit card surcharges are legal in its state.

The second is state law. Credit card surcharging has been legal at the federal level since a class-action settlement between merchants and the major card brands took effect on January 27, 2013.² Roughly four states still prohibit merchants from adding any surcharge to credit card transactions as of 2025. Cash discounts remain legal in those states, but the surcharge itself is not. The list shifts as courts strike down old bans and legislatures add new restrictions, so check your state attorney general’s guidance before you start.

There’s also a practical limit built into the network rules: if credit cards are your only accepted payment method, you generally cannot surcharge at all, because the customer has no fee-free alternative.

How Much You Can Charge

Even where surcharging is legal, the card networks cap what you can add, and the cap has a floor beneath it.

Across every network, the surcharge cannot exceed your actual cost of processing the transaction, known as your merchant discount rate. If your processing rate on a card is 2.1%, your surcharge cannot exceed 2.1%, no matter what other ceiling applies.

On top of that:

Visa caps surcharges at 3% of the transaction amount or the merchant discount rate, whichever is lower. The cap dropped from 4% to 3% in April 2023.³
Mastercard caps surcharges at 4% or the merchant discount rate, whichever is lower.
Discover permits surcharging without a separate registration or waiting period, but the rate must be applied equally to every credit card brand you accept. Surcharge Visa at 2%, and you have to surcharge Discover at 2%.
American Express follows the same equal-treatment principle and requires clear disclosure at the point of sale.

For convenience fees, Visa requires the fee to be a flat dollar amount, not a percentage, and it must apply only to that alternative channel.²

Setting It Up Legally

Turning on surcharging is not a terminal setting you flip. The networks require specific steps, and skipping them is one of the fastest ways to lose your surcharging privileges.

Confirm your state allows it and check for state-specific caps or disclosure rules.
Notify Visa in writing at least 30 days before you begin, submitted through its online portal. Your payment processor can typically handle the Mastercard notification.²
Pull your merchant discount rate for each card brand and set the surcharge at or below the lower of that rate and the network cap.
Update your point-of-sale system so the surcharge appears as a separate line item, not folded into the price.
Post signage at the entrance, at the register, and disclose the fee on the receipt.

For a convenience fee rather than a surcharge, confirm the channel you’re charging on is genuinely an alternative to your primary channel, set the fee as a flat dollar amount, and always give the customer a way to pay through the standard channel without the fee.

How to Disclose the Fee

Disclosure is where enforcement actually hits. The FTC’s Rule on Unfair or Deceptive Fees requires businesses to disclose every charge excluded from the displayed price before the customer is prompted to pay, including the nature, purpose, and amount of the charge. The FTC has stated that vague labels like “convenience fee,” “service fee,” or “processing fee” are not adequate on their own; you have to explain what the fee is actually for.⁴

Visa and Mastercard both require disclosure at three points: the entrance to the business or the website landing page, the point of sale before the transaction is completed, and on the receipt as a separate line item.² The customer must have a clear opportunity to choose a payment method that avoids the fee.

Cash Discounts as a Workaround

If your state bans surcharges or the compliance overhead feels heavy, a cash discount program reaches the same economic result through a different structure. You set your listed prices to include processing costs and offer a discount to customers who pay with cash or debit. The customer’s bottom line is identical, but the two structures are treated very differently under the law.

Federal law explicitly protects merchants’ right to offer discounts for cash, check, or debit payments, and prohibits card networks from restricting that practice.¹ Cash discount programs are legal in all 50 states, including those that ban surcharges. The catch is framing: the discount must read as a reduction from the standard listed price, not a penalty for using a card. Signage, receipts, and pricing all have to reflect the higher price as the baseline.

What Happens If You Get It Wrong

Consequences run from irritating to business-ending. A customer who spots an improper surcharge can file a chargeback, and the network will likely side with the customer. Networks also investigate complaints directly, and repeated violations can bring fines or termination of your merchant processing agreement, which means you lose the ability to accept cards at all.

In states that ban surcharges, the attorney general can pursue enforcement actions carrying civil penalties, and some states allow private lawsuits that can turn into class actions when many customers were affected. The small percentage you save on processing costs is rarely worth the risk of losing card acceptance or defending a lawsuit. The 30-day notification, proper signage, and correct rate math are far cheaper up front than cleaning up a compliance failure afterward.
