Yes, it is legal to charge credit card fees in California in 2026, but only under specific rules. A 2023 federal court decision struck down California’s old ban, opening the door for merchants to add surcharges at checkout.
That said, legal does not mean unlimited. Merchants must follow strict disclosure rules, fee caps, and card network requirements. Getting any of these wrong can still land a business in legal trouble.
This article covers what the law actually says, how much merchants can charge, what different fee types mean, and what your rights are if something seems off at the register.
Is It Legal to Charge Credit Card Fees in California
Credit card fees are legal in California as of 2026, but only with proper disclosure and within specific limits. California’s old surcharge ban under Civil Code Section 1748.1 was effectively overturned by the Ninth Circuit Court of Appeals in the 2023 case Italian Colors Restaurant v. Becerra.
That ruling found the California law violated merchants’ First Amendment rights by preventing them from communicating their pricing differences between cash and credit. After the ruling, merchants in California gained the practical ability to charge customers more for using a credit card.
However, the ruling did not eliminate all rules. Merchants still must comply with Visa and Mastercard network requirements, which carry their own set of conditions. A business that just slaps a fee on your bill without any notice is still acting improperly.
The short version: surcharges are legally permissible in California now, but they come with strings attached. Those strings matter both for businesses trying to stay compliant and for consumers who want to know their rights.
| Status Before 2023 | Status After 2023 Ruling |
|---|---|
| Surcharges banned under Civil Code 1748.1 | Surcharges permitted with proper disclosure |
| Merchants risked fines for adding fees | Merchants must follow network rules and caps |
| Consumers were protected from checkout fees | Consumers must receive advance notice of fees |
| California was in the minority of states | California joined the majority of states |
California Credit Card Surcharge Law 2026
California’s credit card surcharge law in 2026 is shaped by the aftermath of the Italian Colors decision and ongoing Visa and Mastercard network rules. Civil Code Section 1748.1 technically still exists on the books, but its enforcement was halted following the federal court ruling.
California has not passed new legislation replacing the old ban with a clear, updated framework as of early 2026. That creates a gray area that merchants and consumers both need to understand. The practical reality is that merchants are charging surcharges, and courts are not stopping them.
What still applies are the card network rules from Visa and Mastercard. These require merchants to notify customers before they reach the register, cap the surcharge at the merchant’s actual cost of acceptance, and limit surcharges to credit cards only. Debit cards are in a separate category entirely.
Key legal reference: California Civil Code Section 1748.1 remains unenforced for surcharges following the Ninth Circuit’s 2023 ruling in Italian Colors Restaurant v. Becerra.
Think of it like a speed limit sign that’s technically still posted, but the police stopped enforcing it after a court ruled the sign itself was unconstitutional. The sign is there. Nobody’s getting a ticket.
Is It Legal to Charge Credit Card Fees
Credit card fees are legal in most of the United States as of 2026. The majority of states permit merchants to add a surcharge when a customer pays by credit card, as long as certain rules are followed.
The legal foundation nationally comes from a 2013 settlement in a class action lawsuit against Visa and Mastercard, which cleared the way for merchants to pass on processing costs to customers. Before that, card network rules actually prohibited surcharges entirely.
Federal law does not ban surcharges outright. The Dodd-Frank Act addressed debit card fee caps through the Durbin Amendment, but it did not touch credit card surcharges. That left the question largely to individual states.
A small number of states still restrict or limit surcharges more heavily than others. The specific rules differ depending on where you are, which is why many people get confused about what’s allowed.
| Factor | Detail |
|---|---|
| Federal surcharge ban | Does not exist for credit cards |
| States with tighter rules | Colorado, Connecticut (partial restrictions) |
| Card network permission | Visa and Mastercard permit surcharges with rules |
| Surcharge vs. interest | Surcharges are not the same as interest or finance charges |
Is It Illegal to Charge Credit Card Fees
It is not illegal to charge credit card fees in most situations in 2026, but there are specific circumstances where a fee crosses into illegal territory. A merchant who adds a fee without any prior notice, charges more than the actual processing cost, or applies a fee to a debit card transaction may be violating card network rules and, depending on the state, consumer protection laws.
Outright bans on credit card surcharges are rare but still exist in a couple of states. Massachusetts, for instance, has historically maintained a stricter position. California, as discussed, removed the practical ban through the 2023 court ruling.
Where a fee becomes clearly illegal is when it’s disguised. If a merchant charges you a “service fee” or “processing fee” that they never disclosed before you completed the transaction, that can constitute a deceptive trade practice under state consumer protection statutes.
The FTC and state attorneys general take deceptive fee practices seriously. A hidden fee tacked on at the last second is not just an annoyance. It is potentially a legal violation regardless of which state you’re in.
Can Merchants Charge Credit Card Fees in California
Merchants can charge credit card fees in California in 2026, but they must follow the rules set by card networks. The practical ban from Civil Code 1748.1 no longer holds after the Ninth Circuit ruling, but that does not mean anything goes.
A merchant who wants to charge a surcharge in California must: notify customers before the transaction begins, post clear signage at the store entrance and at the point of sale, and include the surcharge on the receipt as a separate line item. Skipping any of these steps puts the merchant in violation of Visa and Mastercard rules.
The surcharge also cannot exceed the merchant’s actual cost to accept that specific card, and it is capped at a hard ceiling regardless. Card network rules trump any individual merchant’s preference for how much they want to charge.
Quick Facts for California Merchants:
- Surcharges are permitted on credit cards only
- Debit cards and prepaid cards cannot be surcharged
- The fee must be disclosed before the customer pays
- The fee must appear as a separate line item on the receipt
- The surcharge cannot be higher than the merchant’s actual processing cost
Is It Legal to Charge Customers for Credit Card Fees
Yes, it is legal to charge customers for credit card fees in California and most other states in 2026, but only credit card transactions qualify. The legality hinges on disclosure, the type of card used, and the amount charged.
The customer must know about the fee before they make the decision to pay. This is not a “we’ll tell you at the end” situation. The disclosure has to happen early enough that the customer can choose to pay with cash or a debit card instead.
Some industries handle this differently. Utilities, government agencies, and some online platforms often use what’s called a “convenience fee” rather than a surcharge. The terminology matters legally. Each term carries a different set of rules.
Charging customers without telling them first is where merchants get into trouble. The fee itself may be legal. The way it’s applied may not be.
Key Takeaway: Credit card surcharges are legal in California in 2026, but the rules around disclosure, card type, and fee caps are strict. Both merchants and consumers benefit from knowing these specifics.
Is It Legal to Charge Credit Card Fees to Customers
Charging credit card fees to customers is legal in California as long as the merchant meets the required conditions. The fee must be for a credit card transaction, not a debit card. The customer must be told about the fee before completing the purchase.
This protects the customer’s right to choose. If you know there’s a 3% surcharge at checkout, you can decide to use a different payment method. If the merchant hides the fee until after you’ve swiped, you’ve been denied that choice, which is where legal and ethical lines both get crossed.
From the consumer’s side, you are not required to pay a surcharge you were never told about. That is a core principle under both California consumer protection law and Visa and Mastercard network rules.
Merchants who handle this correctly face no legal exposure. The ones who get complaints filed against them are almost always the ones who skipped disclosure or applied fees to debit cards.
How Much Can a Merchant Charge for Credit Card Fee California
The maximum a California merchant can legally charge as a credit card surcharge is 3% of the transaction total, or the merchant’s actual cost to accept that card, whichever is lower. This cap is set by Visa and Mastercard network rules, not by California state statute.
In practice, most credit card processing costs for merchants fall between 1.5% and 3.5% depending on the card type. Visa and Mastercard rules say the surcharge cannot exceed the actual cost. So if a merchant’s processing fee for a Visa card is 2.1%, they cannot charge you 3%.
This is an important consumer protection point. The cap is not just 3%. The cap is your actual cost. The 3% is an absolute ceiling, but most merchants should be charging less than that for most transactions.
| Card Type | Typical Merchant Processing Cost | Max Allowed Surcharge |
|---|---|---|
| Visa Credit | 1.5% to 2.5% | Actual cost, capped at 3% |
| Mastercard Credit | 1.5% to 2.6% | Actual cost, capped at 3% |
| Amex Credit | 2.3% to 3.5% | Actual cost, capped at 3% |
| Debit Card (any) | Varies | Cannot be surcharged |
| Prepaid Card | Varies | Cannot be surcharged |
Credit Card Surcharge Rules California
California credit card surcharge rules in 2026 require merchants to follow a specific set of procedures to avoid violating card network agreements and consumer protection principles. These are not suggestions. Violations can result in removal from card network programs.
The rules, drawn from Visa and Mastercard merchant agreements, require merchants to register their intent to surcharge with the card network before they start charging. Merchants cannot simply wake up one day and start adding fees. They must formally notify the card networks in advance.
After registering, merchants must post clear notice at the store entrance, at the point of sale, and on the receipt. The surcharge must be listed as a separate line item on every receipt. The total price including the surcharge must always be displayed.
California Merchant Surcharge Checklist:
- Register with Visa and/or Mastercard before charging any surcharge
- Post signage at store entrance and point of sale
- Disclose the surcharge percentage clearly before the transaction
- Include the surcharge as a separate line item on the receipt
- Never apply a surcharge to debit card or prepaid card transactions
- Keep the surcharge at or below actual processing cost, never above 3%
California Credit Card Fee Disclosure Requirements
California credit card fee disclosure requirements in 2026 are built around a straightforward principle: the customer must know before they pay. Merchants must post visible notice of any surcharge at the store entrance and at the checkout point.
For online businesses, the disclosure must appear before the customer finalizes the purchase. It cannot be buried in fine print at the bottom of a terms page. The fee must be visible and clearly stated before the payment is processed.
For brick-and-mortar locations, signage must be clear enough that a reasonable person would notice it before reaching the register. A tiny sticker on the payment terminal does not cut it. The disclosure must be meaningful.
Receipts must show the surcharge as its own line item. Not lumped into the total. Not hidden as a rounding difference. A separate, labeled line that says what the charge is for.
Merchants who skip disclosure do not just risk customer complaints. They risk being reported to Visa or Mastercard and potentially losing the ability to accept those cards entirely. That is a serious business consequence.
Key Takeaway: The disclosure rules for California credit card fees are not bureaucratic red tape. They are the legal foundation that makes surcharges permissible. Skip disclosure, and the whole fee becomes legally questionable.
Surcharge vs Convenience Fee California
A surcharge and a convenience fee are not the same thing, and in California the distinction matters legally. A surcharge is a fee added specifically because the customer chose to pay with a credit card. A convenience fee is charged when a customer uses a payment channel that is not the merchant’s standard method.
Here is a practical example. A restaurant that normally takes cash and charges you extra for using a card is applying a surcharge. A utility company that normally processes payments in person but charges you extra for paying online is applying a convenience fee.
Card network rules treat these differently. Convenience fees can be charged on both credit and debit cards in certain situations. Surcharges cannot be applied to debit cards at all.
Convenience fees also do not have to match the merchant’s exact processing cost the way surcharges do. They need to be reasonable and disclosed, but the calculation rules differ.
| Feature | Surcharge | Convenience Fee |
|---|---|---|
| Applies to credit cards | Yes | Yes |
| Applies to debit cards | No | Sometimes |
| Must match processing cost | Yes | No exact match required |
| Requires pre-registration with card networks | Yes | Different rules apply |
| Common in which industries | Retail, restaurants | Utilities, government, online |
Cash Discount Program California
A cash discount program is a legal alternative to a surcharge that many California merchants use in 2026. Instead of adding a fee for credit card users, the merchant advertises a higher price and then gives a discount to customers who pay with cash.
The result for the customer is the same: cash customers pay less, card customers pay more. But the legal framing is different. Cash discounting is explicitly permitted under federal law, including provisions that survived the Dodd-Frank Act.
California merchants using cash discount programs must still be transparent. The posted price must be the credit card price. The cash discount must be clearly communicated. Advertising a lower price and then charging more at the register is deceptive regardless of what you call it.
Cash discount programs are popular with small businesses because they often avoid the card network registration requirements that come with formal surcharge programs. That administrative simplicity makes them attractive, but the transparency requirements still apply in full.
If a merchant tells you the price is 5% less for cash, that is legal. If they charge you the higher price and call it a “cash discount program” without ever showing you a lower cash price, that is not compliant.
Can a Business Charge for Using a Credit Card
Yes, a business can charge for using a credit card in California in 2026. The 2023 Ninth Circuit ruling removed the practical enforceability of the old California ban. Businesses now have the legal ability to add a fee.
That said, not every business can do this without preparation. A business must register with Visa and Mastercard before imposing a surcharge. They must post signage. They must cap the fee correctly. A business that skips these steps is exposing itself to card network penalties and potential consumer complaints.
Service industries sometimes have their own additional considerations. Attorneys, healthcare providers, and licensed professionals may have separate rules governing how they can bill clients, which can layer on top of the general surcharge rules.
Online businesses in California face the same rules as physical stores. The fee must be disclosed before checkout is completed. The receipt or order confirmation must break it out as a separate line item.
The practical takeaway: yes, any California business can charge for credit card use in 2026. The conditions for doing it legally are specific and must be followed every time, not just occasionally.
Key Takeaway: A business can legally add a credit card fee in California in 2026, but the fee must be disclosed in advance, capped correctly, and applied only to credit card transactions. Missing any of these conditions creates legal exposure.
Debit Card Surcharge California
Merchants cannot legally charge a surcharge on debit card transactions in California or anywhere else in the United States in 2026. This is one of the clearest lines in payment law. Visa and Mastercard rules explicitly prohibit surcharges on debit card transactions, and the Dodd-Frank Act’s Durbin Amendment also addressed debit card fee regulation at the federal level.
The distinction between credit and debit matters a great deal. A customer using a debit card that runs through the Visa or Mastercard network cannot be charged a surcharge, even though the card looks identical to a credit card and processes through the same terminal.
Merchants who apply surcharges to debit card transactions are violating card network rules outright. This can result in fines from the card networks and, if the behavior is systematic, removal from the network entirely.
Some merchants confuse this by labeling their surcharge as a “service fee” that applies to all card transactions. That label does not make it legal for debit cards. The nature of the transaction controls, not what the merchant calls the fee.
If you were charged a surcharge on a debit card purchase in California, you have grounds to dispute the charge with your bank and file a complaint with the card network. That is a clear-cut violation.
Is Charging a Credit Card Fee Illegal in California
Charging a credit card fee is not illegal in California in 2026 when done correctly, but it was illegal before the 2023 court ruling and is still improper if the rules are not followed. The line between legal and illegal depends entirely on how the fee is applied.
A properly disclosed, correctly capped surcharge on a credit card transaction is legal. A hidden fee, an undisclosed fee, a fee applied to a debit card, or a fee that exceeds the merchant’s actual processing cost is all impermissible under the current framework.
The old California Civil Code Section 1748.1 made surcharges illegal outright. That law still exists in text, but its enforcement against merchants was enjoined by the federal court. The practical effect is that California no longer enforces the ban.
However, other enforcement mechanisms remain. Card network rules, FTC consumer protection principles, and California’s Unfair Competition Law (Business and Professions Code Section 17200) can all be used against merchants who charge fees deceptively or without proper disclosure.
Deceptive fee practices are still illegal in California. The surcharge itself is not illegal. The deception around it is.
California Credit Card Fee Consumer Rights
California consumers have specific rights when it comes to credit card fees in 2026. The most important is the right to be informed before you pay. If a merchant does not disclose a surcharge before you complete the transaction, you have the right to dispute that charge.
You can dispute an undisclosed surcharge with your credit card issuer. Card networks require merchants to follow disclosure rules, and a failure to disclose is a violation of merchant agreements. Your card issuer can initiate a chargeback process on your behalf.
California’s Unfair Competition Law gives consumers and the state attorney general the ability to challenge deceptive business practices. If a merchant is systematically adding undisclosed fees, they could face regulatory action from the California AG.
You can also file a complaint with the California Department of Consumer Affairs, the FTC, and directly with Visa or Mastercard’s merchant compliance departments. Card networks take these complaints seriously because their own rules are at stake.
Consumer Rights Quick Reference:
- You must be told about any surcharge before you pay
- You cannot be surcharged for using a debit card
- You can dispute an undisclosed fee with your card issuer
- You can file a complaint with the California AG or the FTC
- The surcharge cannot exceed 3% or the merchant’s actual processing cost
Credit Card Processing Fee Laws by State
Credit card processing fee laws vary significantly by state in 2026, and California is not an outlier. Most states now permit surcharges with conditions, but a few maintain tighter restrictions.
Massachusetts has historically maintained a stronger position against surcharges, though the legal landscape there has also been challenged in courts. Connecticut has placed limits on the amount and type of disclosure required. Colorado passed its own legislation in recent years requiring clear disclosure and capping surcharges.
The majority of states follow the card network rules without adding state-level requirements on top. That means in most of the country, if you follow Visa and Mastercard’s rules, you are compliant with state law as well.
| State | Surcharge Status (2026) | Notable Rules |
|---|---|---|
| California | Permitted with disclosure | Post-2023 ruling; 3% cap applies |
| Massachusetts | Restricted | Historical ban, ongoing legal debate |
| Connecticut | Permitted with limits | Disclosure and cap requirements |
| Colorado | Permitted with disclosure | State disclosure law enacted |
| New York | Permitted with disclosure | Must show total price with fee |
| Texas | Permitted | Follows card network rules |
| Florida | Permitted | Disclosure required |
The overall trend nationwide is toward permitting surcharges with disclosure requirements. The days of blanket bans are giving way to regulated transparency. Knowing your state’s specific rules protects both merchants and consumers.
What Is the Maximum Credit Card Surcharge Allowed
The maximum credit card surcharge allowed in California and across the United States is 3% of the transaction total. This cap is set by Visa and Mastercard network rules, not by a single federal statute, and it applies to merchants who accept those cards.
The 3% cap is an absolute ceiling. But the actual maximum a merchant can legally charge is the lower of 3% or their actual cost to accept that specific card. If their processing fee for a particular Visa card is 2.2%, they cannot charge you 3%. They can only charge up to 2.2%.
American Express historically had different rules, but as of recent years, Amex surcharge rules have been brought closer in line with Visa and Mastercard. The 3% cap effectively covers most card surcharge situations a consumer will encounter.
Some merchants post a flat surcharge percentage, like 2.5%, that applies to all credit cards. This approach is common and generally permissible as long as the flat rate does not exceed the merchant’s highest actual processing cost for any card type.
A surcharge above 3% is a clear violation of card network rules regardless of what state you are in. If you are charged more than 3% as a surcharge at any merchant, you have clear grounds to dispute it.
Key Takeaway: The maximum legal credit card surcharge is 3%, but merchants can only charge up to their actual processing cost. A surcharge above 3% is always a violation of card network rules, and merchants who apply fees above this face network penalties.
