Is It Illegal for Businesses to Charge a Card Fee? 2026

Charging a card fee is legal for businesses in most US states, but a handful of states ban the practice, and federal law sets strict rules about how and when fees must be disclosed. Whether the fee you were charged was legal depends on where you live and exactly how the business structured the charge.

The question comes up constantly because credit card processing fees have been rising, and more businesses are passing that cost to customers in 2026. A surprising number of consumers and merchants don’t know the actual rules.

One important fact most people miss: there is a significant legal difference between a credit card surcharge, a convenience fee, and a cash discount program. The law treats them very differently.

This article covers which states ban card fees, what the federal rules say, the caps and disclosure requirements businesses must follow, and what rights you have as a consumer when you think you’ve been charged illegally.

Is It Illegal for Businesses to Charge a Card Fee?

Charging a card fee is not universally illegal for businesses in the United States, but it is regulated by both state law and card network rules that create real legal exposure when those rules are violated. The legality depends on the state, the type of fee, and how it is disclosed.

At the federal level, no law specifically prohibits businesses from charging customers more for credit card payments. The Dodd-Frank Act addressed debit card fees through the Durbin Amendment but left credit card surcharging largely to state law and card network contracts. The result is a patchwork of state rules ranging from outright prohibition to no restriction at all.

In states that allow surcharges, businesses must still follow disclosure rules and cap requirements set by card networks. A business that adds a fee without proper disclosure, or that exceeds the allowed cap, may be violating those rules even in a state where surcharges are otherwise legal.

Quick Facts:

• Card fees for credit cards are legal in most US states.
• A small number of states ban credit card surcharges entirely.
• Federal law does not prohibit credit card surcharges but regulates debit card fees.
• Card network rules (Visa, Mastercard) cap surcharges at 3% as of 2023.
• Surcharges must be disclosed before the transaction in all states that allow them.
• Debit card surcharges are generally prohibited under the Durbin Amendment (Dodd-Frank Act).

Credit Card Surcharge Laws by State

Credit card surcharge laws by state vary from total prohibition to complete permission, with a small number of states falling somewhere in between. As of 2026, the majority of US states allow businesses to charge credit card surcharges when proper rules are followed.

The states with active surcharge prohibitions or restrictions are a shrinking group. Several state bans were struck down or narrowed by federal courts following the Supreme Court’s 2017 decision in Expressions Hair Design v. Schneiderman, which held that surcharge prohibitions implicated First Amendment speech concerns when they restricted how prices were communicated rather than what prices could be charged.

Understanding your state’s law is the starting point for both merchants and consumers. A business that charges a fee in a ban state is violating state law. A business that charges a fee in a permissive state while violating disclosure rules is violating card network rules, which can result in losing the ability to accept that card brand.

Most states not listed have no specific surcharge statute, meaning surcharges are legal subject to card network rules and general consumer protection disclosure requirements.

States Where Credit Card Surcharges Are Banned

States with active credit card surcharge bans in 2026 include California, Connecticut, and Massachusetts, though the number of prohibition states has declined significantly over the past decade as courts struck down bans on First Amendment grounds.

California’s ban under Civil Code Section 1748.1 prohibits merchants from imposing a surcharge on customers who pay with a credit card. The California Attorney General enforces this provision, and violations can result in civil penalties. California’s ban survived a First Amendment challenge in state court, distinguishing it from the New York ban that the Supreme Court addressed in 2017.

Connecticut’s ban under CGS Section 42-133ff is among the oldest and most actively enforced in the country. Connecticut allows merchants to offer discounts for cash payment but prohibits adding a surcharge to the credit card price. The distinction between a discount and a surcharge is one the Connecticut courts take seriously.

States with active surcharge bans or significant restrictions:

Several other states that previously had surcharge bans, including New York, had their bans altered or narrowed by court decisions. The current legal landscape is more permissive than it was before 2017.

Key Takeaway: California and Connecticut are the two states with the most clearly active and enforced credit card surcharge bans in 2026. Most other states allow surcharges when proper disclosure and cap rules are followed.

Is a Credit Card Surcharge Legal Under Federal Law?

A credit card surcharge is not prohibited by federal law for most retail transactions. No federal statute directly bans merchants from adding a percentage to transactions paid by credit card. Federal law’s primary role in this space is through the Dodd-Frank Act, which addressed debit cards specifically rather than credit cards.

The Durbin Amendment, part of the Dodd-Frank Wall Street Reform and Consumer Protection Act, regulated debit card interchange fees paid by merchants to banks. It did not create a right for merchants to surcharge debit cards and in fact is often interpreted to discourage debit card surcharging through its network rules implications.

Federal courts have addressed state surcharge bans through the First Amendment lens. The Supreme Court’s 2017 decision in Expressions Hair Design v. Schneiderman held that New York’s surcharge ban, as applied to specific pricing communication practices, raised First Amendment concerns. The Court remanded the case for further proceedings, and subsequent lower court decisions have shaped how state bans can be written and enforced.

Federal legal framework for card fees:

• No federal statute bans credit card surcharges for general retail transactions.
• Dodd-Frank Act regulates debit card interchange fees, not surcharges to consumers.
• Truth in Lending Act (TILA) requires disclosure of credit costs in certain lending contexts.
• First Amendment case law (Expressions Hair Design) limits how states can ban surcharges.
• CFPB has authority over consumer financial products but has not banned credit card surcharges.

Convenience Fee vs Surcharge: The Legal Difference

A convenience fee and a credit card surcharge are legally distinct fee types that are treated very differently by state laws and card network rules. Confusing the two is one of the most common mistakes merchants make when trying to recover card processing costs legally.

A credit card surcharge is a percentage added to a transaction solely because the customer chose to pay with a credit card. Surcharges apply to all credit card transactions and are the type of fee that state surcharge bans target. They are the focus of most legal controversy around card fees.

A convenience fee is a fixed fee charged for using a specific payment channel, typically an alternative or non-standard payment method, such as paying a utility bill online instead of in person. Convenience fees are generally permitted under card network rules even in states with surcharge bans, because they are tied to the payment channel rather than the payment instrument. They must be disclosed clearly before the transaction is completed.

The practical difference for merchants: a surcharge is a way to pass on processing costs for card payments. A convenience fee is a way to charge for the service of accepting an alternative payment method. Structuring the fee correctly matters for legal compliance.

Cash Discount Program vs Surcharge: What Is Legal?

A cash discount program is a pricing structure where a business posts a higher regular price that includes a discount for cash payers, rather than adding a fee to card users. It is legal in all 50 states and permitted under all major card network rules, making it the most legally safe way for merchants to recover card processing costs.

The key legal distinction is in how the price is framed. In a surcharge arrangement, the base price is the cash price and the card fee is added on top. In a cash discount program, the posted price reflects the full amount, and customers who pay cash receive a reduction. The economic outcome for the consumer may be identical, but the legal treatment is completely different.

Card networks including Visa and Mastercard specifically allow cash discount programs even where they prohibit or restrict surcharges. The Durbin Amendment also explicitly protects a merchant’s right to offer discounts for different payment methods. This makes cash discount programs a legally safe alternative for merchants in both surcharge-ban states and permissive states.

Cash discount vs surcharge compliance comparison:

Many merchants in ban states have switched to cash discount programs to legally recover processing costs without violating surcharge prohibitions. The programs require proper signage and clear communication but are fully legal everywhere.

Is It Legal to Charge a Debit Card Fee?

Charging a surcharge for debit card transactions is generally prohibited or heavily restricted in the United States, even in states where credit card surcharges are allowed. The Durbin Amendment to the Dodd-Frank Act created a different regulatory environment for debit card transactions than for credit cards.

Under 12 CFR Part 235 (Regulation II), which implements the Durbin Amendment, debit card transactions are subject to specific interchange fee regulations. While the Durbin Amendment addressed the fees that banks charge merchants rather than fees merchants charge consumers, the practical effect, combined with card network rules, has been to create strong barriers against debit card surcharges.

Visa’s and Mastercard’s merchant rules specifically prohibit merchants from surcharging debit card transactions, even in states that permit credit card surcharges. A merchant who violates these network rules risks losing the ability to accept Visa or Mastercard entirely, which is a far more serious business consequence than any state law penalty.

Debit card fee legal status:

The bottom line for merchants: surcharging debit cards is a much riskier legal and contractual position than surcharging credit cards, even in states where credit card surcharges are fully permitted.

Key Takeaway: Debit card surcharges are effectively prohibited by card network rules even where state law might technically allow them. Merchants can surcharge credit cards in most states but should not surcharge debit cards under any network rules.

Credit Card Surcharge Disclosure Requirements

Credit card surcharge disclosure requirements apply in every jurisdiction that permits surcharges and are strictly enforced by card networks even in states with no specific surcharge law. Failing to disclose a surcharge properly is a violation regardless of whether the surcharge itself is legal.

At the point of sale, merchants must notify customers of the surcharge before the transaction is completed. This notification must occur at the store entrance or website landing page, at the point of sale terminal, and on the receipt. The notice must state the surcharge as a percentage of the transaction amount, and the receipt must show both the surcharge amount and the total charge.

Visa’s surcharge rules as of 2026 require that merchants provide written notice to their acquiring bank at least 30 days before implementing a surcharge. Failure to provide this advance notice is itself a rule violation. Mastercard has similar requirements. Both networks require that the surcharge be clearly disclosed on the receipt as a separate line item.

Required surcharge disclosures:

• Notice at store entrance or website landing page before customer commits to purchase.
• Notice at point of sale terminal before payment is processed.
• Receipt showing surcharge as a separate line item.
• Surcharge must be expressed as a percentage, not a flat dollar amount.
• Notice must state that the surcharge does not exceed the merchant’s actual processing cost.
• Advance notice to the card network’s acquiring bank (typically 30 days before implementation).

Merchants who surcharge without meeting these disclosure requirements can face card network sanctions including loss of card acceptance rights, even if the state law technically permits the surcharge.

What Is the Maximum Credit Card Surcharge Allowed?

The maximum credit card surcharge a merchant can charge is 3% of the transaction amount as of 2023 under Visa and Mastercard network rules. This cap applies nationwide regardless of state law. A merchant cannot charge more than 3% even in states with no specific surcharge restriction.

Prior to 2023, the cap was set at 4% by Visa and Mastercard. The reduction to 3% was part of a settlement agreement and applies to all merchants who accept these card brands. American Express has its own rules for merchants who accept Amex, and those rules have historically required merchants to treat Amex cardholders the same as other card brand users.

The surcharge also cannot exceed the merchant’s actual cost of acceptance (the merchant discount rate), so if a merchant’s actual processing cost is 2.1%, the maximum allowable surcharge is 2.1%, not 3%. This rule prevents merchants from using surcharges as a profit center rather than a cost recovery mechanism.

Surcharge cap rules by card network:

A merchant charging 4% or more as a card surcharge is violating network rules in 2026, regardless of whether the state prohibits or permits surcharges generally.

Visa and Mastercard Surcharge Rules for Merchants

Visa and Mastercard have their own surcharge rules that apply to all merchants who accept their cards, independent of state law. These private contractual rules carry significant weight because violating them can result in losing card acceptance rights, which is often a more immediate and damaging consequence than any state law penalty.

Visa’s surcharge rules require merchants to register their surcharge program with Visa at least 30 days before implementation. The surcharge must be applied uniformly to all Visa credit card transactions. It cannot be applied selectively to some Visa cards and not others. The surcharge cannot exceed the merchant’s actual processing cost or 3%, whichever is lower.

Mastercard’s rules are nearly identical in structure. Both networks require that the surcharge apply only to credit cards, not to debit or prepaid cards. Both require that the surcharge be disclosed clearly at the point of sale. Both prohibit surcharging in states with active surcharge bans, meaning even the card network’s own rules acknowledge state law restrictions.

Visa and Mastercard surcharge rule compliance checklist:

• Register surcharge program with acquiring bank and card network 30 days in advance.
• Apply surcharge only to credit cards, not debit or prepaid cards.
• Cap surcharge at lower of 3% or actual processing cost.
• Apply uniformly to all credit card transactions of that brand.
• Disclose at store entrance or website, at point of sale, and on receipt.
• Do not surcharge in states where prohibited by law.
• Apply the same surcharge across all card types of that brand (no brand-specific targeting).

Connecticut Credit Card Surcharge Law

Connecticut prohibits credit card surcharges under Connecticut General Statutes Section 42-133ff, making it one of the most consistently enforced surcharge ban states in the country. The law prohibits any seller in any retail sales transaction from imposing a surcharge on a buyer who uses a credit card.

Connecticut’s law has been on the books since 1984 and has survived legal challenges. The state’s approach differs from the New York law that went to the Supreme Court in 2017; Connecticut’s implementation has been upheld in courts applying a different analysis to the state’s enforcement mechanism.

Violations of Connecticut’s surcharge ban are enforced by the Connecticut Attorney General under the Consumer Protection Act. Merchants who violate the prohibition can face civil penalties. Connecticut allows merchants to offer a cash discount, meaning a lower price for cash-paying customers, as long as the credit card price is posted as the standard price. The discount structure is legal; the surcharge structure is not.

Connecticut surcharge law specifics:

Connecticut merchants who want to recover card processing costs should use a cash discount program rather than a surcharge, which is the legally compliant path under Connecticut law.

California Credit Card Surcharge Law

California prohibits credit card surcharges under California Civil Code Section 1748.1, which states that no retailer in any sales transaction may impose a surcharge on a cardholder who elects to use a credit card in lieu of payment by cash, check, or similar means. California’s ban is among the most actively enforced in the United States.

California’s law faced a major First Amendment challenge. In 2017, the Ninth Circuit Court of Appeals addressed California’s law after the Supreme Court issued its decision in Expressions Hair Design v. Schneiderman. The Ninth Circuit ultimately upheld California’s surcharge ban on remand, finding that it regulated conduct (the act of imposing a surcharge) rather than speech about prices, which is a different constitutional analysis than the New York law.

California consumers who are charged a credit card surcharge by a merchant can report the violation to the California Attorney General or pursue a private right of action under California consumer protection statutes, including the Consumer Legal Remedies Act (CLRA) and Unfair Competition Law (UCL).

California surcharge law specifics:

California merchants who violate this law face not just regulatory penalties but private lawsuits from consumers seeking actual damages, injunctive relief, and attorney’s fees under the CLRA.

Key Takeaway: California and Connecticut have the most actively enforced credit card surcharge bans in 2026. Both allow cash discount programs as a legal alternative. Both expose merchants to civil penalties and consumer lawsuits for violations.

Consumer Rights When a Business Charges a Card Fee

Consumers have specific rights when a business charges a card fee illegally, including the right to report the violation to state attorneys general, file a complaint with card networks, and in some states, pursue a private lawsuit for damages. What rights apply depends on the state and whether the fee violated state law, card network rules, or both.

In California, consumers can file a private lawsuit under the Consumer Legal Remedies Act and the Unfair Competition Law for violations of the credit card surcharge ban. These statutes allow recovery of actual damages, injunctive relief, and attorney’s fees, making private enforcement financially viable in California. In Connecticut, similar consumer protection statutes support private claims.

In states where surcharges are permitted, a consumer’s rights focus on disclosure violations rather than the fee itself. If a business charged a card fee without proper advance disclosure, it may have violated card network rules and state consumer protection laws that require clear disclosure of all fees before a transaction is completed.

Consumer options when charged an illegal or undisclosed card fee:

Card network chargeback rules allow consumers to dispute charges that were not properly disclosed before the transaction. This is separate from state law and applies in all states.

Can You Dispute a Credit Card Surcharge?

You can dispute a credit card surcharge charge with your card issuer when the fee was not properly disclosed before the transaction was completed. Card network rules require pre-transaction disclosure of surcharges, and failure to provide that disclosure gives consumers a valid basis for a dispute.

A chargeback dispute for an undisclosed surcharge is filed directly with your credit card issuer, not with the merchant. You would identify the charge as unauthorized or not matching the disclosed terms of the transaction. The card issuer then investigates through the card network’s dispute resolution process.

Disputing a surcharge that was properly disclosed is a different situation. If the merchant clearly disclosed the surcharge before you completed the transaction and you proceeded anyway, the dispute basis is weaker. In states where the surcharge is illegal regardless of disclosure, you can argue the charge itself was unauthorized under state law, which creates a stronger dispute basis.

Steps to dispute an illegal or undisclosed card fee:

1. Gather documentation: receipt showing the surcharge, any signage photos if available.
2. Contact your card issuer by phone or through the card’s app to initiate a dispute.
3. Identify the dispute reason: undisclosed fee or fee charged in violation of state law.
4. The issuer will investigate and may provisionally credit your account during the process.
5. File a complaint with the state attorney general in states with surcharge bans.
6. Report to the card network (Visa or Mastercard) through their merchant reporting process.

The dispute process typically takes 30 to 45 days to resolve. Provisional credits may be provided during the investigation.

Expressions Hair Design v Schneiderman and Surcharge Law

Expressions Hair Design v. Schneiderman is the 2017 Supreme Court case that fundamentally changed how courts analyze state credit card surcharge bans. The case reached the Supreme Court from the Second Circuit and addressed whether New York’s surcharge ban violated the First Amendment.

The Supreme Court held 8-0 that New York’s surcharge ban implicated First Amendment free speech concerns because it regulated how merchants communicated their prices, not just what prices they could charge. The Court did not strike down the law but remanded the case to the Second Circuit to apply the correct First Amendment analysis. On remand, New York’s ban was largely invalidated as applied to the pricing communication practices of the merchant plaintiffs.

The case’s legacy is that it created a First Amendment framework for challenging state surcharge bans. States that ban surcharges must now write and enforce those bans in a way that regulates conduct rather than speech about prices. California’s ban has survived on this basis; New York’s effectively did not.

Expressions Hair Design case summary:

For merchants and consumers in 2026, this case matters because it explains why some state bans were struck down and others survived, creating the current patchwork of state laws.

CFPB and Dodd-Frank Act Rules on Card Fees

The Consumer Financial Protection Bureau (CFPB) has authority over consumer financial products and has addressed card fees primarily through its supervision of card issuers rather than direct regulation of merchant surcharges. The Dodd-Frank Act’s Durbin Amendment, which the CFPB helps implement, is the most directly relevant federal law for card fees.

The Durbin Amendment (Section 1075 of Dodd-Frank) required the Federal Reserve to establish rules limiting debit card interchange fees. Regulation II (12 CFR Part 235) implements these rules, capping debit card interchange fees for large issuers at 21 cents plus 0.05% of the transaction amount. This reduced the cost of debit card acceptance for merchants but did not directly regulate what merchants can charge consumers.

The CFPB in 2024 finalized a rule capping late fees for large credit card issuers at $8. This rule, while addressing consumer costs on the card issuance side, does not directly govern merchant surcharges to consumers. The agency’s authority over merchant pricing practices is limited compared to its authority over card issuers.

Dodd-Frank and CFPB key provisions affecting card fees:

The practical conclusion for merchants: federal law is not the primary source of surcharge restrictions. State law and card network rules are what matter most for compliance in 2026.

Frequently Asked Questions

Is it illegal for a business to charge a fee for using a credit card?

It is not illegal for businesses to charge a card fee in most US states, but a small number of states, including California and Connecticut, ban the practice.
In states that allow surcharges, businesses must follow disclosure rules and cap the fee at no more than 3% of the transaction amount under Visa and Mastercard network rules.
Debit card surcharges are prohibited by card network rules even in states where credit card surcharges are allowed.
Businesses that charge undisclosed fees or exceed the allowed cap violate card network rules regardless of state law.

Which states ban credit card surcharges in 2026?

California and Connecticut have the most clearly active and enforced credit card surcharge bans in 2026.
California’s ban is under Civil Code Section 1748.1; Connecticut’s is under CGS Section 42-133ff.
Massachusetts has restrictions on how surcharges can be communicated.
Several other states that previously had bans had them narrowed or struck down following the Supreme Court’s 2017 Expressions Hair Design decision.

What is the maximum credit card surcharge a business can charge?

The maximum credit card surcharge is 3% of the transaction amount under Visa and Mastercard network rules as of 2023.
The surcharge also cannot exceed the merchant’s actual cost of acceptance, so if processing costs are 2%, the maximum surcharge is 2%, not 3%.
These caps apply in all states where surcharges are permitted; they cannot be exceeded even with consumer consent.
Prior to 2023, the cap was 4%; the reduction to 3% resulted from a settlement agreement between the card networks and merchants.

What can I do if a business illegally charges me a card fee?

File a complaint with the state attorney general in states that ban credit card surcharges, such as California and Connecticut.
Contact your card issuer to dispute the charge if the surcharge was not disclosed before you completed the transaction.
In California, you may have a private right of action under the Consumer Legal Remedies Act and Unfair Competition Law.
Report the merchant to the card network (Visa or Mastercard) through their merchant complaint process if network rules were violated.

Is charging a card fee different from a cash discount program?

Yes, a surcharge and a cash discount program are legally very different, though the economic effect can be identical for consumers.
A surcharge adds a fee on top of the listed price for card users; a cash discount program sets the listed price to include card costs and then reduces it for cash payers.
Cash discount programs are legal in all 50 states and permitted under all card network rules, including in states that ban surcharges.
Merchants in ban states like California and Connecticut use cash discount programs as the legally compliant way to recover processing costs.

The rules around card fees have gotten more complicated as processing costs have risen and more businesses look to pass those costs on to customers. The core rule remains straightforward: check your state’s law, follow card network caps and disclosure rules, and consider a cash discount program if you’re in a ban state.
