Passing on debit card fees to customers is not the same decision as adding a credit-card surcharge. Visa’s published U.S. merchant Q and A says you cannot surcharge a Visa debit card or prepaid card. Choosing “credit” on the PIN pad does not change the product. The card is still debit.
If the question you meant was about a 3% fee on credit, that answer is on whether charging the customer 3% is illegal. This page stays on debit.
This is not legal advice. Card-network rules are not statutes. State law can add its own limits. Read the current documents for your store.
What Visa currently publishes about debit
The U.S. Merchant Surcharge Q and A we retrieved on 2026-09-10 from Visa’s PDF (version 02152024) answers the debit question twice.
Surcharging is limited to credit cards. Debit cards and prepaid cards cannot be surcharged.
A debit cardholder who picks “credit” on the terminal is still using a debit card. The PIN-versus-signature choice is not a product change.
That is a network-rule problem even in a state that allows credit surcharges. A register that adds the same percentage to every card will fail a debit test. Run a physical debit card through your dual-price or surcharge setup before you turn it on.
Mastercard publishes its own credit-only surcharge rules. Do not copy Visa’s debit ban from a sales deck. Read the current Mastercard surcharge rules for that brand.
Why “is it legal” and “do the networks allow it” get mixed up
Search results for this question often say debit surcharges are illegal under federal law. We are not going to repeat that as a statute citation, because the document we can check and date is Visa’s merchant Q and A, not a United States Code section on merchant debit surcharges.
The Durbin Amendment limits what networks can charge merchants in debit interchange. It is a wholesale-cost rule. It is not a permission slip to add a fee on the customer’s debit sale, and it is not, by itself, the sentence you should put on a window sign.
State law is a third layer. Visa’s same Q and A told merchants to consult counsel on state and federal restrictions, and listed Visa’s understanding as of February 15, 2024. That list is dated. A 2016 statute compilation is more dated still. Check your attorney general and an attorney licensed where the store sits.
SNAP is separate and clearer for stores: a SNAP tender cannot pay more than the cash customer. That path rings the cash price. Details are on the EBT and SNAP page.
What to do at the register if you already pass fees on
Test debit, prepaid, and SNAP as their own tenders. If the extra line still appears, the program is mis-set, whatever the window sign says.
If you want the customer to carry card cost without a surcharge, dual pricing and cash discount are a different model with different posting rules. Start with cash discount and dual pricing and whether dual pricing is legal. Debit and SNAP still have to match the model you actually signed.
If you want to keep paying the processor yourself, compare effective rates instead of adding a line. Counter Club’s published in-person sample is 2.50% plus $0.10. Sample pricing applies to new accounts applying directly. Pricing is subject to underwriting, MCC and the merchant agreement; rates may differ and are subject to change. See pricing.
A processor who cannot show debit excluded from a surcharge program is not ready to turn the program on. Send the agreement if you want a second read on which tenders it actually covers.
Frequently asked questions
Can I surcharge debit if my state allows credit surcharges? Not under Visa’s published Q and A. The product is still debit.
Is a cash discount on debit the same as a surcharge? No. Visa treats a discount for paying another way separately from a fee added on card. The receipt decides which one you are running.
What if my gateway cannot tell debit from credit? Do not run a surcharge program on it. BIN-level debit detection is the test, not a logo on the plastic.
Does this apply to prepaid gift cards? Visa’s Q and A groups prepaid with debit: they cannot be surcharged.
Where should I read first? Visa’s current surcharge Q and A, Mastercard’s current surcharge rules, your merchant agreement, and your state’s current statute. In that order, then counsel.
