A merchant adding a fee for credit card payments has to give notice in four places: to the card networks before starting, to customers at the store entrance or before online checkout, again at the point of sale, and once more on the receipt. Those are the core credit card surcharge notice requirements set by Visa and Mastercard, and several states add their own on top. Each notice has to state the exact surcharge percentage and make clear that debit and prepaid cards are not surcharged.
Thirty-Day Notice to the Card Networks
Before charging a single customer, a merchant must give written notice to Visa, Mastercard, and its acquiring bank at least 30 days in advance.1Visa. U.S. Merchant Surcharge Q and A This is not internal paperwork. It is the gateway to the entire framework, and beginning to surcharge without it puts the processing relationship at risk from day one.
Mastercard runs a dedicated online form. The merchant provides the business name and contact information, the number of locations, the sales channel (in-store, online, mail order, or phone order), and whether the surcharge is applied at the brand level or the product level.2Mastercard. Mastercard Credit Card Surcharge Rules and Fees for Merchants Visa collects the same kind of detail through the merchant’s acquiring bank.1Visa. U.S. Merchant Surcharge Q and A Both networks need the specific percentage the merchant intends to charge.
The 30-day window gives the networks time to verify that the proposed surcharge falls within their caps and gives the acquiring bank time to update its compliance monitoring. It also fixes an official start date, which becomes useful evidence if anyone later questions when disclosures began.
Entrance and Point-of-Sale Signage
Inside a physical store, Visa requires surcharge disclosures at three locations: the point of entry, the point of sale, and on every receipt.1Visa. U.S. Merchant Surcharge Q and A The entrance sign is the one merchants most often skip. A customer who does not learn about the surcharge until they are already at the register has been denied the chance to pay a different way or shop elsewhere, and that is the scenario the rule exists to prevent.
Visa publishes sample language merchants can use verbatim. For a percentage-based surcharge, the recommended text reads: “We impose a surcharge of [X]% on the transaction amount on Visa credit card products, which is not greater than our cost of acceptance. We do not surcharge Visa debit cards.”3Visa. Sample Surcharge Disclosure Signage Merchants that accept multiple card brands can combine the brand names on a single sign. The disclosure has to state the exact percentage. A vague reference to “a small processing fee” does not satisfy the rule.
Mastercard’s rules also require disclosure at the point of sale and on the receipt, though Mastercard’s published guidance focuses less on entrance-specific placement.4Mastercard. Mastercard Frequently Asked Questions Merchant Surcharge Posting at the entrance satisfies the stricter of the two networks, so a merchant who accepts both cards should meet Visa’s placement standard everywhere. High-contrast lettering and a readable font size are what actually make the sign do its job.
Online Checkout Disclosure
For e-commerce, the surcharge has to be disclosed before the customer completes checkout. Visa’s rules require merchants to alert consumers to the practice online in the same manner as in-store, meaning the notice needs to be visible at or before the point of sale rather than tucked into a terms-of-service page.1Visa. U.S. Merchant Surcharge Q and A
The safest placement is the payment-method selection page or the order summary, where the customer can still change how they pay. Some merchants also show the notice on product pages or on the first page displaying card logos. Any of those work as long as the percentage appears before the customer confirms the order. A notice that only surfaces on the confirmation screen after payment is too late.
Merchants selling into multiple states face an added question. Visa’s guidance says merchants follow the surcharge laws of the state where their business outlet is located.1Visa. U.S. Merchant Surcharge Q and A Some state regulators take a different view and apply their consumer protection laws when their residents are the buyers. An online seller based in a surcharge-friendly state but shipping nationwide should confirm the position of any state whose residents it charges regularly.
Receipt Line Item
Every receipt, printed or emailed, must show the surcharge as its own line.1Visa. U.S. Merchant Surcharge Q and A It cannot be folded into item prices or added to sales tax. The customer needs to see three separate figures: the purchase subtotal, the surcharge, and the total charged to the card.
Mastercard requires the receipt to disclose the practice as well, and the label should identify the charge as a credit card surcharge rather than a generic “service fee” or “convenience fee.”4Mastercard. Mastercard Frequently Asked Questions Merchant Surcharge Most modern point-of-sale systems handle this automatically once the surcharge percentage is programmed. The receipt then doubles as an audit trail: if a customer disputes the charge or a network investigates, the labeled line proves the disclosure was made.
The Debit and Prepaid Exemption Belongs on the Notice
Surcharges apply only to credit cards. Both networks prohibit surcharging debit and prepaid cards, and that holds even when a debit card is run as a “credit” transaction with a signature instead of a PIN.3Visa. Sample Surcharge Disclosure Signage Card type controls, not the processing method.
This affects the signage itself, which is why Visa’s sample language includes the explicit line about not surcharging debit. It also affects the point-of-sale configuration behind the notice. A terminal that adds the surcharge to every card transaction will inevitably apply it to a debit card and put the merchant out of compliance regardless of how the sign reads. The notice and the system have to match.
The Percentage on the Notice Must Be Accurate
The rate the merchant discloses is not a marketing number. A surcharge cannot exceed the merchant’s actual cost of acceptance, meaning interchange plus network and acquirer fees. If the effective rate is 2.4%, the sign cannot say 3%.4Mastercard. Mastercard Frequently Asked Questions Merchant Surcharge1Visa. U.S. Merchant Surcharge Q and A Because nearly every merchant accepts both, the working ceiling is usually 3%.
The calculation uses the merchant’s average effective rate over either the prior month or the prior twelve months, at the merchant’s option. Processing costs move, so the allowable percentage moves with them. A merchant who set a rate a year ago should recalculate before assuming the number on the sign is still defensible.
State Rules That Change the Notice
Network rules set the nationwide baseline, but state law can override them. Roughly a dozen states and territories either ban credit card surcharging outright or add restrictions beyond what the networks require. The landscape shifts as courts weigh in and legislatures adjust, so a merchant needs to check the current rule in each state where it operates.
The state variations that most often change how a merchant has to give notice fall into a few groups:
- Outright bans, where no surcharge is allowed regardless of what the sign says.
- All-in pricing, where the posted price has to include the credit card price, with any lower cash price shown separately, rather than a fee added at the register.
- Lower caps, with some states setting ceilings as low as 1% or 2%, which becomes the number that has to appear on the sign.
- Enhanced disclosure, where the merchant must inform the customer verbally at the point of sale, or must display cash and credit prices with equal prominence wherever prices appear.
Multi-location businesses follow the law of each store’s state individually. A merchant with one location in a surcharge-friendly state and another in a state that bans the practice can surcharge at the first but not the second.1Visa. U.S. Merchant Surcharge Q and A State penalties for noncompliance run independently of the networks and, in some states, reach $500 per transaction.
What Happens When the Notice Is Missing or Wrong
Visa’s enforcement begins with a $1,000 fine assessed to the acquiring bank on the first identified violation, along with a demand for a remediation plan.1Visa. U.S. Merchant Surcharge Q and A Penalties escalate monthly if the problem is not fixed, and the acquiring bank typically passes them through to the merchant or ends the processing relationship.
Losing card acceptance is the outcome sitting behind all of this. The fastest ways to get there are surcharging debit cards, surcharging above the cap, or failing to post a disclosure at all. State enforcement runs on a separate track through the attorney general or consumer affairs offices, so a merchant whose notices are out of order can face penalties from both sides at once.
