Credit card surcharge laws by state: what's legal in 2026

Surcharging, adding a small percentage to a customer's total when they pay by credit card, has become a lot more common as processing costs climb and business owners look for a way to offset them. The legal landscape has also shifted a lot over the last several years, with most states now allowing it after a wave of laws were struck down or repealed. But 'most states' isn't 'all states,' and even where it's legal, the card networks layer their own rules on top of state law. This guide walks through where things stand in 2026, what the card networks require everywhere, and how surcharging differs from cash discounting.

This is a fast-changing area of law, so treat this as a starting point and confirm current rules for your specific state before adding a surcharge to your receipts, a call to your state attorney general's office or a payments attorney is worth the hour. Our guide to credit card processing fees explained is a good companion piece if you're weighing whether surcharging is worth doing at all.

Is credit card surcharging legal in 2026?

Yes, in most states. A series of state bans were challenged in court over the last decade on First Amendment grounds, and most states have since repealed or stopped enforcing outright surcharge bans. As of 2026, the great majority of states allow surcharging as long as you follow disclosure rules. A small number of states still have restrictions on the books or add extra conditions, and this list has been shrinking, not growing, over the last several years.

What do Visa and Mastercard require even where surcharging is legal?

State law is only half the picture. Even in a state where surcharging is fully legal, Visa and Mastercard both require merchants to follow their own program rules before you can add a surcharge. Skipping these steps can put your merchant account at risk regardless of what state law allows.

• Register your intent to surcharge with your card processor, who notifies the card networks, this is mandatory, not optional.
• Cap the surcharge at your actual cost of acceptance, generally capped around 3% by the card networks.
• Surcharge all card brands the same way, or don't surcharge any of them, you can't single out one network.
• Post signage at your entrance and again at the point of sale disclosing the surcharge.
• Show the surcharge as a separate line item on the receipt, not folded into the price.
• Never surcharge a debit card, even one processed as "credit" at the terminal.

You can read the current program requirements directly from Visa's surcharging rules and Mastercard's merchant surcharge rules, which is a good habit any time you're about to add a fee at checkout.

How is surcharging different from a cash discount?

Both approaches try to offset processing costs, but they're structured differently and treated somewhat differently under the rules. A surcharge adds an amount on top of a base price when a customer pays by credit card. A cash discount instead sets a higher regular price and gives a discount to anyone paying cash or debit, technically, everyone is offered the discount, and credit card users simply don't take it.

Some businesses find cash discounting simpler to implement cleanly, since it doesn't require the same registration step, though the card networks still expect clear signage either way. We cover both approaches side by side, including how to test either one without upsetting regulars, in our guide to zero fee credit card processing.

How much can you legally surcharge?

Card network rules cap surcharges at around 3% or your actual cost of acceptance, whichever is lower, you can't use a surcharge to make a profit on payments, only to recover what processing actually costs you. Some states that allow surcharging set their own lower cap, so the real ceiling in your location is whichever number is lower: your state's cap or the card network's cap.

This means the calculation starts with knowing your actual effective rate, walk through how to calculate it in our credit card processing fees explained guide before setting a surcharge percentage.

Signage and disclosure requirements

Both card networks and most state laws that permit surcharging require clear, visible disclosure before the customer commits to paying. This typically means:

• A sign at the store entrance stating that a surcharge applies to credit card purchases.
• A second notice at the point of sale or checkout screen, restating the exact percentage.
• For online sellers, disclosure before the payment page, not buried in terms and conditions.
• The surcharge itemized as its own line on the final receipt.

What should you do before adding a surcharge?

1. 1Confirm current surcharge law for your specific state, and every state you operate in if more than one.
2. 2Calculate your actual effective processing rate so your surcharge doesn't exceed real cost.
3. 3Register your intent to surcharge with your processor before turning it on.
4. 4Set up compliant signage at your entrance and point of sale.
5. 5Configure your POS or terminal to apply the surcharge only to credit cards, never debit.
6. 6Watch customer response for a few weeks, surcharging can save money and also cost you regulars who feel nickel-and-dimed.

What does this mean for Minnesota businesses?

Minnesota law permits credit card surcharging as long as businesses follow disclosure requirements and the card network rules above, but state guidance can be updated, so confirm current status with the Minnesota Attorney General's office before setting one up, especially if you operate locations in more than one state.
