Credit card surcharge rules, state by state.

Yes — it is legal to charge customers a credit card fee in most U.S. states, provided you follow the card networks' rules: surcharge credit cards only, disclose the fee clearly before payment, and never charge more than the card actually costs you to accept. The exceptions are the point of this page: Connecticut, Massachusetts, and Maine still ban surcharging outright, a growing list of states cap it below the network ceiling, and New York will fine you per sale if the price display is wrong. Here's the full picture, current as of July 2026. For the bigger picture — how common surcharging has become, the merchant economics, and what customers think — see our 2026 credit card surcharging report.

The baseline: network rules apply in every state

Before any state law enters the picture, Visa and Mastercard set the floor for every U.S. merchant. Their surcharge rules boil down to five requirements:

• Credit cards only — never debit or prepaid. Debit surcharging is prohibited everywhere, a position rooted in the federal Durbin Amendment. That includes debit cards run as "credit" (signature debit), so your terminal must detect card type and drop the fee automatically.
• Cap: the lesser of your cost or the network limit. Visa caps surcharges at 3% (lowered from 4% in April 2023); Mastercard's cap is 4%. Since virtually every merchant accepts both, 3% is the practical ceiling nationwide.
• No profit. The surcharge may never exceed your actual cost of acceptance. If your effective rate is 2.4%, a 3% surcharge is non-compliant even where 3% is otherwise allowed.
• Advance notice to your acquirer. Networks require notice — commonly at least 30 days — before your first surcharged transaction. Your processor usually files the paperwork; "I turned it on in the terminal menu" is not registration.
• Disclosure at every step. Signage at the store entry and the point of sale (or before checkout online), and the surcharge as a separate line item on the receipt.

State law can only tighten this baseline, never loosen it. Which brings us to the map.

Surcharge laws by state — the 2026 tracker

The table lists every state with its own restriction. If your state isn't listed, surcharging is permitted there under the network baseline above — disclose it, cap it, and keep it off debit.

Last reviewed: July 22, 2026. Surcharge legislation is moving fast — treat this table as a starting point, and confirm current law with your acquirer or counsel before you start surcharging.

Two trends worth watching. First, states are shifting from outright bans to cost caps and disclosure rules — Oklahoma's 2025 flip from ban to regulated-permission is the template. Second, Illinois-style interchange-on-tax laws target what banks may charge you rather than what you may charge customers; if the Illinois act survives appeal in 2027, expect copycats.

Surcharge vs cash discount vs dual pricing

These three get conflated constantly, and the legal treatment differs:

• A surcharge adds a fee on top of the posted price when the customer pays by credit card. It's what this page — and every law above — regulates.
• A cash discount reduces the posted price for cash payers. It's lawful in all 50 states — even the ban states explicitly permit discounts, and federal law protects them.
• Dual pricing displays both a cash price and a card price up front, so the customer chooses with full information. Done honestly, it satisfies even the strict display states.

The trap is the mislabeled program: if the register adds a "non-cash adjustment" to the shelf price, that's a surcharge no matter what the vendor calls it — and it's judged under surcharge law. The full breakdown, including when each model makes sense, is in our guide to dual pricing vs cash discounting vs surcharging.

Compliance checklist

If you decide to surcharge, run this list before the first fee hits a receipt:

• Check your state's row above — and if you sell into multiple states (e-commerce counts), comply with the strictest one you touch.
• Notify your acquirer/processor at least 30 days before you start, and confirm the registration actually happened.
• Disclose everywhere: signage at the entry and point of sale, disclosure before checkout online, and the surcharge as its own line item on every receipt.
• Credit only, enforced by the terminal. The system must recognize debit and prepaid BINs and remove the fee automatically — a cashier judgment call will fail.
• Cap it at the lesser of your actual cost, 3%, and your state's cap — then re-check annually, because your effective rate moves.
• Never profit. Know your true cost of acceptance — our effective rate calculator gives you the number from one monthly statement.

Before you surcharge: run the math on your rate first

Surcharging solves a real problem — processing costs are painful — but it solves it by charging your customers, and some of them will notice, complain, or leave. Before taking that trade, it's worth asking why the cost is painful in the first place. In our experience the answer is often an inflated markup: a flat-rate plan or a padded tier hiding what the card networks actually charge. Moving to transparent interchange-plus pricing — and fixing downgrades, batch habits, and Level 2/3 data on commercial cards — frequently recovers a meaningful share of what a surcharge would, without touching the customer experience.

Our position is boringly practical: get your true cost down first, then decide if a surcharge is still worth it. The playbook is in how to lower your credit card processing fees — or skip ahead and send us one statement for an honest interchange-plus rate review. No application fee, and you'll know your real cost of acceptance either way — a number you're required to know before you surcharge anyway.
