Is Surcharging Credit Cards Legal in My State in 2026

Surcharging a credit card is legal in most U.S. states only when two stacks of rules both say yes: the card brand's surcharge program, and the statute of the state or territory where the sale happens. Visa's U.S. credit surcharge may not exceed the merchant discount rate for that card or 3 percent, whichever is lower. You must notify your acquirer 30 days before the first surcharged sale. Debit and prepaid are never eligible, including when the customer taps "credit" on the PIN pad. Connecticut, Massachusetts, and Maine still prohibit the fee in current statute. Visa's U.S. Merchant Surcharge Q and A, version dated February 15, 2024, also lists Puerto Rico as a prohibition. If you operate in one of those four, stop. If you do not, run the sequence below before you flip a terminal setting.

This is a decision sequence, not a 50-state table, and it is not legal advice. Confirm the current text with your acquirer, your state attorney general, and counsel.

1. 1
   Read the outlet's law. Connecticut, Massachusetts, and Maine ban it in statute. Visa also lists Puerto Rico. Other states cap or condition. Check the attorney general, not a blog map.
2. 2
   Keep it off debit and prepaid. Visa forbids both. A debit card run as credit is still debit.
3. 3
   Cap the fee. Lower of your credit merchant discount rate or 3 percent. A flat 3 percent fails if your cost is 2.4 percent.
4. 4
   Notify the acquirer 30 days out. Visa requires notice before the first surcharged sale. Your processor must populate the surcharge field.
5. 5
   Disclose three times. Point of entry, point of sale, and an itemized line on every receipt.

Network rules that apply in every state

Surcharging is a fee added only to a credit transaction. Visa's public surcharge materials (the February 15, 2024 Q and A and the August 14, 2023 considerations sheet) are the floor everywhere you accept Visa. State law can tighten that floor. It cannot waive it.

The rules that fail most programs:

• Credit only. Debit and prepaid cannot be surcharged. Visa is explicit that the credit-or-debit prompt on a terminal is signature versus PIN, not a license to surcharge a debit card.
• The cap is the lower of two numbers. U.S. merchants may assess a surcharge that does not exceed the merchant discount rate for that credit card, or 3 percent, whichever is lowest. The August 14, 2023 sheet restates the ceiling in a footnote: even if cost of acceptance is higher than 3 percent, you cannot assess above 3 percent.
• 30-day acquirer notice. Visa's small-business regulations page and the Q and A both require notice at least 30 days before you begin. The acquirer enables Visa Field 28, the dedicated surcharge data field.
• Disclosure at entry, at the sale, and on the receipt. Posted at the door (or the first online page that references card brands), shown again at the point of sale, and itemized on the receipt. Visa publishes sample signage on the same regulations page.
• Brand level or product level, not both. All Visa credit the same way, or selected Visa credit products the same way. Do not mix the two methods.

Visa also says it mystery-shops, and that the acquirer of a merchant identified as surcharging improperly may be assessed an immediate $1,000 fine (Q and A, February 15, 2024). That fine lands on the acquirer and becomes your shutdown.

The 3 percent number is a ceiling, not a quote

Work the cap on a real rate. The example below is illustrative.

Take an $80 credit sale. Your merchant discount rate on that Visa credit product is 2.40 percent. Visa's cap is the lower of 2.40 percent and 3 percent, so 2.40 percent. The largest compliant surcharge is $80 × 0.0240 = $1.92. A terminal set to a flat 3 percent would add $2.40, which is $0.48 over the discount rate and a rule break on every ticket.

Flip it. Same $80 sale, cost of acceptance 3.20 percent. The 3 percent brand cap now binds: $80 × 0.03 = $2.40, not $2.56. You do not recover the extra 20 basis points through the surcharge.

If you do not know the credit discount rate on the products you actually take, you cannot set a legal surcharge. That number lives on the statement, not on a rate card. Surcharge, dual pricing, and cash discount are three different programs. Pick one on purpose.

Four jurisdictions that still say no

Connecticut. Conn. Gen. Stat. § 42-133ff, current compilation on the General Assembly site (including P.A. 24-142, effective June 6, 2024): "No person may impose a surcharge on any transaction." A surcharge is any additional charge or fee that increases the total for the privilege of using a particular method of payment. A discount to induce cash, check, debit, or similar means is allowed if you post notice. A violation is an unfair or deceptive trade practice, and the Commissioner of Consumer Protection may add a civil penalty of up to $500 per violation.

Massachusetts. Mass. Gen. Laws ch. 140D, § 28A(a)(2): no seller may impose a surcharge on a cardholder who elects to use a credit card in lieu of cash, check, or similar means. The same section protects a discount offered to all prospective buyers and disclosed clearly.

Maine. Me. Rev. Stat. tit. 9-A, § 8-509 (page data extracted October 20, 2025) bans a surcharge on a cardholder who elects to use a credit card or a debit card. A discount or reduction from the regular price is not a surcharge. The Maine Bureau of Consumer Credit Protection restates the rule: you cannot advertise a lower price and then add a card fee, and if both prices are shown the listed (card) price must be at least as noticeable as the cash price. Governmental entities have a separate, disclosed exception. Private merchants do not.

Puerto Rico. Visa's February 15, 2024 Q and A lists Puerto Rico among the jurisdictions it understands to prohibit surcharging. Confirm the Commonwealth statute with local counsel before you treat that as settled.

Visa's same Q and A also listed Oklahoma as a prohibition and listed Colorado, Minnesota, New Jersey, and New York as having extra requirements, as of February 15, 2024. That is Visa's understanding on that date, not a 2026 enforcement map. Some states still have older surcharge language on the books that courts have limited. The National Conference of State Legislatures compilation (updated October 13, 2016) is a list of texts, not a current yes/no. If your state is not one of the four named above, you still read the attorney general and the brand registration packet. You do not skip to a 3 percent toggle.

Surcharge is not a cash discount

A surcharge adds a fee to a credit ticket. Dual pricing posts two prices. A cash discount subtracts from a posted price when the customer pays cash. A "cash discount" that adds 3 percent at the PIN pad is a surcharge, and it inherits every Visa rule and every state ban, whatever the sign says.

Surcharge is also one of six pricing models, not a substitute for knowing your markup. If the program only exists to hide a rate you would not put on a proposal, fix the rate.

More than one location

Visa's Q and A is direct: the merchant outlet follows the law of the state where that outlet sits. A Connecticut store cannot surcharge. A store you own in a state that allows it may, if you registered, capped, and disclosed that outlet. Ecommerce, invoices, and phone orders need disclosure on the first page that shows card brands, and a gateway that will not surcharge debit cards.

A legal program is a configuration. The POS has to identify credit versus debit versus prepaid at authorization, apply the cap, and print the surcharge as its own receipt line. Signage has to match the amount you charge. The acquirer file has to show 30 days' notice. If any one of those is missing, you do not have a surcharge program. You have a complaint.

If you need the credit mix and the real discount rate before you pick a number, run a statement through the analyzer and use the as-billed credit cost as the ceiling, then take the lower of that figure and 3 percent.

FAQ

Is it legal to add a credit card surcharge in my state in 2026? In most states, yes, if you also follow card-brand rules: credit only, a cap at the lower of your merchant discount rate or 3 percent, 30-day acquirer notice, and disclosure at entry, the register, and the receipt. Connecticut, Massachusetts, and Maine still ban the fee in statute. Visa's February 15, 2024 Q and A also lists Puerto Rico as a prohibition.

Can I surcharge a debit card if the customer chooses credit on the terminal? No. Visa's U.S. Merchant Surcharge Q and A (February 15, 2024) forbids surcharges on debit and prepaid. Choosing credit on the PIN pad is still a debit card. Signature debit is still debit.

What is the maximum credit card surcharge under Visa rules? The lower of your merchant discount rate for that credit card or 3 percent. If your cost of acceptance is 2.4 percent, a 3 percent surcharge is too high. If your cost is 3.2 percent, you still cannot go above 3 percent.

Do I have to notify anyone before I start surcharging? Yes. Visa requires notice to your acquirer at least 30 days before the first surcharged sale, plus disclosure at entry, at the point of sale, and as a separate receipt line. Starting because a terminal toggle was flipped is how programs get shut off.

If my state bans surcharging, can I run a cash discount instead? Often yes, if it is a real discount off a posted price. Connecticut, Massachusetts, and Maine each protect discounts from the regular price when they are disclosed. A cash discount that adds 3 percent at checkout is a surcharge under another name.

I have locations in two states. Can I surcharge in only one of them? Yes, if that outlet's state allows it and you follow brand rules there. Visa's February 15, 2024 Q and A says each outlet follows the law of the state where it sits. Confirm ecommerce and phone-order treatment with counsel.
