States where credit card surcharging is banned in 2026

The 40-second answer

As of 2026, Connecticut, Massachusetts, and Maine prohibit credit-card surcharges, and Puerto Rico bans them as well. If your business is in one of those places, you cannot legally tack a credit-card fee onto a posted price. The good news: you can still drop your card-processing cost toward zero anywhere in the country — you just have to do it with a cash discount instead of a surcharge. A discount is legal in all 50 states, including the ban states, because it's the opposite move: you post the card price and give a break for paying cash.

The states that ban surcharging

The list of outright bans is short, and it's the same in 2026 as it has been recently:

• Connecticut — It's illegal for merchants to surcharge one payment type over another. Connecticut can fine a business $500 per violation.
• Massachusetts — State law (M.G.L. Ch. 140D § 28A) makes it unlawful for a seller to impose a surcharge on a buyer who chooses to pay by credit card. The ban has been upheld in court.
• Maine — Businesses can't add a surcharge when a customer pays by credit card. (Government entities in Maine are a narrow exception — they may surcharge on things like taxes, fines, and permit fees.)
• Puerto Rico — Surcharging on credit-card transactions is prohibited.

Beyond the outright bans, several other states layer on their own signage, disclosure, or cap requirements even where surcharging is allowed. That's why — even if your state isn't on the banned list — it's worth confirming the exact rules before you turn a surcharge on.

The caps where surcharging IS allowed

If you're in a state that permits surcharging, the card networks still cap how much you can charge. Visa limits a credit-card surcharge to 3% (or your actual cost of acceptance, whichever is lower). Mastercard caps it at 4%. If you accept both — and almost everyone does — you're effectively limited to 3%. Some states go lower: Colorado, for example, caps surcharges at 2%. A surcharge can only ever be applied to credit cards, never debit, and you have to register it with the networks, post clear notice at your door and register, and itemize it on the receipt. Get any of that wrong and you can face network fines on top of any state penalty. For the full breakdown, see is surcharging legal?.

The legal alternative that works everywhere: cash discounting

Here's the part that matters most for ban-state merchants. A cash discount — and its clearer cousin, dual pricing — is legal in all 50 states, full stop. The mechanics are simple: your posted or menu prices are the card prices, and customers who pay with cash or debit get a discount at checkout. Because that's framed as a discount rather than an added fee, the surcharge bans in Connecticut, Massachusetts, Maine, and Puerto Rico don't reach it. You get the same economic result — card fees stop eating your margin — with none of the state-by-state legal map to memorize. That's exactly why I usually set merchants up on dual pricing: it behaves the same way in every state.

How to stay clean, whichever route you take

Whether you surcharge (where allowed) or run a cash-discount program (anywhere), three things keep you compliant: clear disclosure so customers see the price difference before they pay, correct programming so the fee or discount applies to the right transactions within network rules, and a processor who configures it properly on your terminal or POS. A sloppy setup — surcharging in a ban state, missing signage, or hiding a fee — is what creates real exposure. Done right, these programs are routine and completely legitimate.
