Even though it is annoying to have an extra fee tacked onto your purchase, you will likely continue to encounter these surcharges. Here’s what you need to know about these fees.

The short answer is yes, it is legal for a merchant to impose a surcharge. A U.S. Supreme Court ruling in 2017 protected surcharges as a form of free speech from merchants. Retailers can also require a minimum purchase amount when you use credit cards. Before the Supreme Court ruling, merchants won the right to add surcharges or “checkout” fees in a 2013 class action lawsuit against card issuers and banks. Part of the reason why surcharges have been allowed is that businesses themselves are charged when they accept credit cards. These fees on businesses generally range from 1% to 3% of every transaction. (Fees for debit cards may be lower than credit card fees.) Businesses may also pay per-transaction costs. In some industries, such as those that rely on small purchases, it’s hard to make a profit when customers pay with a credit card. However, there are limitations to how merchants impose these fees. If merchants decide to use credit card surcharges, they must:

Clearly disclose the fact that there is a surcharge before the transactionDisplay the credit card surcharge on the receipt.Keep surcharges below 4% of the transaction, or the amount of the fees the merchant pays to the credit card companies, whichever is less.

Minimum Purchase Requirements

The financial crisis-era Dodd-Frank Wall Street Reform and Consumer Protection Act allowed retailers to set minimum purchase requirements for credit cards. These minimums can’t be more than $10, and the minimum can’t be set higher than what other merchants in the same card network use. In the past, retailers weren’t allowed to set minimums or add surcharges. But some merchants were “unofficially” setting minimum purchase amounts. Those practices were not necessarily illegal at the time, but they were a violation of the merchant’s agreement with their payment-processing services. While it’s entirely legal for merchants to impose credit card surcharges, many are slow to adopt them. That could be because:

Some merchants, like many consumers, may not know the legality of surcharges.Merchants are hesitant to annoy customers or create the perception that they’re nickel-and-diming customers.Surcharging in some industries might be more complicated than it’s worth. For example, when accepting payments from clients who use health insurance, a surcharge could complicate the billing process.

States on Credit Card Surcharges

While it’s legal under federal law to add a surcharge to credit card transactions, some states prohibit the practice. Some of these states had addressed this issue even before the 2013 law addressed it on a national level. As of Sept. 14, 2020, 10 states and Puerto Rico have laws prohibiting merchants from charging these fees. These states are California, Colorado, Connecticut, Florida, Kansas, Maine, Massachusetts, New York, Oklahoma, and Texas. Minnesota prohibits merchants from imposing surcharges on credit cards they themselves issue to customers (for example, Target couldn’t impose a surcharge on RedCard transactions).

What Happens When a Merchant Breaks the Rules?

Merchants regularly break the rules. Regulations are confusing for everybody, and some merchants innocently break the rules because they don’t understand them. Others intentionally choose not to follow them. Large companies should be well aware of the rules, and they likely receive ongoing guidance from legal and corporate teams. Any business with a loyal following can notify customers that they prefer not to take credit cards, and the business might even be able to offer discounts for cash purchases (though it may depend on state law). If a business is blatantly breaking the rules and you want to take meaningful action, you can report the business to credit card companies. Those payment networks have signed agreements with merchants that prohibit such activity. Report violations by calling your card issuer (using the number on the back of your card) or submit a complaint online. Depending on the state laws in your area, you may also be able to report the merchant to your state’s attorney general.
