La réponse courte
Not every state allows a credit card surcharge, and the ones that do set different caps and sign rules, so a business that sells in more than one state needs a policy per location, not one policy copied everywhere. Our state guide lists Connecticut, Maine, Massachusetts and Puerto Rico as places that prohibit surcharges. Colorado lets merchants choose either a 2% cap or the actual processing fee they pay, and Minnesota allows up to 5% by statute, but Visa's own rules cap surcharges at 3% and forbid them on debit and prepaid cards everywhere. Check each location's state rule and the card network rules before you change a receipt. General information, not legal advice.

This page is general information, not legal advice, current as of October 19, 2026. CELER Merchants is an independent merchant services agent, not a law firm or a processor. Surcharge rules come from state law, the card networks and your merchant agreement, and they change. Confirm your setup with your processor and your own counsel before you add or change a surcharge.
Why one policy rarely fits every state
Many businesses copy a surcharge setup from a supplier, a franchise peer or a business in another state. The trouble is that the rule follows the location of the sale. A setup that is legal in one store can be prohibited in a store across the state line, capped lower in another, and need different sign wording in a third. Online and phone sales add another question: which state's rules apply to that sale. Ask your counsel how your own online and phone sales should be treated.
Three kinds of state rules
| Kind of rule | Examples | What it means for you |
|---|---|---|
| Surcharges prohibited | Connecticut, Maine, Massachusetts, Porto Rico | No credit card surcharge at locations there. Discounts for other payment methods are treated differently; read each state's page |
| Allowed with a state cap | Colorado (choose 2% or your actual processing fee), Minnesota (up to 5%) | The lower of the state cap and the card network cap is the one that binds |
| Allowed with state disclosure rules | New York (post the total card price), New Jersey and Oklahoma (show the amount on the notice) | Signs, menus and checkout pages may need different wording by state |
The card network rules sit on top
Whatever the state allows, the card networks set their own floor of rules for US merchants. Visa allows surcharges on credit cards only, never on debit or prepaid cards, even when a debit card is run as credit. Visa caps the surcharge at 3%, requires notice to your acquirer at least 30 days before you start, and requires disclosure at the point of entry, at the point of sale and on the receipt. Mastercard also limits surcharges to credit cards. That is why Minnesota's 5% statute does not let a merchant charge 5% on Visa cards.
Build the policy location by location
Start with a list of every place you take card payments: each store, each website and each phone line. For each one, write down the state, whether surcharging is allowed there, the cap that applies, and the sign wording required. Where surcharging is prohibited, switch the surcharge off for that location's merchant ID and devices, and look at the alternatives on our cash discount pages instead. Then run a test sale with a credit card and a debit card at each location and read both receipts.
What changes for multi-location and enterprise operations
Larger groups usually have a central pricing team, several merchant IDs and many device types. Make surcharging a setting that is approved per merchant ID, not switched on for the whole account. Keep a register of which locations surcharge, at what rate, under which state rule, and when it was last checked. When you open a site in a new state, add the surcharge check to the opening list, alongside signs and receipts. Ask your provider for written confirmation of how surcharging is configured on each merchant ID, and recheck it after any hardware or software change.
