Yes, it is legal to pass credit card fees to customers in most U.S. states in 2026, but the rules governing how you do it are specific, and violations carry real financial consequences. The short answer is that surcharging is permitted in roughly 48 states, but only if you follow card network disclosure requirements and cap the fee correctly.
Most people assume this is a simple yes or no question. It is not. Two states still ban credit card surcharges outright. Card networks impose a national cap on how much you can charge. And disclosure requirements must be met before every transaction.
Here is the fact that catches most merchants off guard: the 2023 Visa and Mastercard settlement reduced the maximum allowable surcharge from 4% to 3%. Many businesses are still charging 4% in 2026, which puts them in violation of current card network rules.
This article covers every layer: federal law, state-by-state rules, the updated card network requirements, disclosure obligations, and exactly what consumers can do when a surcharge crosses the legal line.
Is It Legal to Pass Credit Card Fees to Customers
Yes, it is legal to pass credit card fees to customers in most U.S. states, but legal does not mean unrestricted. Merchants must comply with card network rules, state law, and federal disclosure requirements simultaneously. Violating any one of these layers creates legal and financial exposure.
The legal foundation for credit card surcharging in the United States was established most clearly by the Supreme Court’s 2017 decision in Expressions Hair Design v. Schneiderman. That case addressed whether surcharge ban laws violated the First Amendment. The Court held that states can regulate how surcharges are communicated but cannot simply ban merchants from passing their processing costs to consumers in most circumstances.
Following that decision, most state surcharge bans were either repealed or significantly narrowed. As of 2026, only Connecticut and Massachusetts maintain outright bans on credit card surcharges for consumer transactions.
Key legal requirements for passing credit card fees to customers legally:
- The surcharge cannot exceed 3% of the transaction value (Visa and Mastercard post-settlement cap)
- The surcharge cannot exceed your actual cost of credit card acceptance
- You must notify the card network at least 30 days before implementing surcharging
- The surcharge must be clearly disclosed before the transaction is completed
- You cannot surcharge debit card transactions, even those processed as credit
- The surcharge must apply equally to all credit cards of the same brand
The 3% cap is the single most violated rule in 2026. Many merchants switched to surcharging after the rules relaxed but never updated their systems when the cap dropped from 4% to 3%.
Can Merchants Charge Credit Card Fees to Customers
Merchants can charge credit card fees to customers in 48 U.S. states as of 2026, subject to specific card network rules and state disclosure requirements. The two states where merchants cannot charge these fees are Connecticut and Massachusetts.
The ability to surcharge credit card transactions is a relatively recent development in U.S. law. For decades, card network rules prohibited merchants from charging customers more for using a credit card. That prohibition ended for most states following a 2013 antitrust settlement between merchants and Visa and Mastercard, which allowed surcharging to begin as state bans were addressed one by one.
The merchant’s ability to surcharge depends on several variables:
| Factor | Requirement | Consequence of Violation |
|---|---|---|
| State law | Must be in a non-ban state | Violation of state consumer protection law |
| Card network notification | 30 days advance notice to Visa/Mastercard | Loss of card acceptance rights |
| Surcharge cap | Maximum 3% or actual cost, whichever is lower | Card network penalty, consumer claim |
| Pre-transaction disclosure | Must disclose before payment is processed | Card network penalty, consumer claim |
| Debit card exclusion | Cannot surcharge debit transactions | Card network penalty |
The 30-day notification requirement to card networks is one of the most commonly skipped steps by small merchants. A merchant who starts surcharging without notifying Visa or Mastercard is violating their merchant agreement from day one, regardless of whether they comply with every other rule correctly.
Is It Legal to Charge a Credit Card Processing Fee
Yes, charging a credit card processing fee is legal in most states, and the practice has grown significantly among small businesses since card network rules were updated to allow it. The fee must be structured as a surcharge (not a penalty), disclosed before the transaction, and capped within the card network limits.
The term “credit card processing fee” is the consumer-friendly way of describing what payment professionals call a “checkout surcharge.” The legal framework treats them identically. Whether you call it a processing fee, a swipe fee, or a convenience charge, the same rules apply.
The key legal distinction is between a fee charged to recover your actual processing costs versus a fee that exceeds those costs. Surcharge rules require that the fee cannot exceed either 3% or your actual merchant discount rate, whichever is lower. A merchant whose processor charges them 2.2% cannot legally charge customers a 3% fee. The cap is the lower of the two numbers.
Processing fee legal requirements in practice:
- Know your actual merchant discount rate before setting the surcharge percentage
- Set the surcharge at or below the lower of 3% or your actual rate
- Never apply the surcharge to debit card transactions processed as credit
- Display the surcharge clearly at the point of entry to your location and at the point of sale
- Include the surcharge as a separate line item on the customer’s receipt
The requirement to itemize the surcharge on the receipt is particularly important for consumer transparency and for your own compliance documentation. A lump-sum price increase without a separate surcharge line item may be treated as a prohibited hidden fee by state consumer protection authorities.
Key Takeaway: Charging a credit card processing fee is legal in 48 states, but the fee must not exceed 3% or your actual processing cost, must be disclosed before the transaction, and must appear as a separate line item on the receipt.
Is It Legal to Add a Credit Card Fee at Checkout
Adding a credit card fee at checkout is legal in most states, but the method of disclosure at the point of checkout determines whether the surcharge is legally compliant. A fee disclosed before the customer commits to the transaction is compliant. A fee added after the customer has already decided to purchase is not.
The timing of disclosure is the element most often handled incorrectly by merchants who otherwise have a legitimate surcharging program. Card network rules require that the surcharge be disclosed at the “point of entry” (when a customer enters the store or accesses the payment page online) and at the “point of sale” (at the payment terminal before the customer completes the transaction).
A sign posted only on the front door is not sufficient. The disclosure must also appear at the register or payment terminal. For e-commerce merchants, the disclosure must appear on the checkout page before the customer submits payment, not on a confirmation screen afterward.
Correct and incorrect disclosure approaches:
| Disclosure Method | Compliant | Notes |
|---|---|---|
| Sign at store entrance plus terminal disclosure | Yes | Both points required |
| Terminal disclosure only | Partially | Missing point-of-entry disclosure |
| Receipt disclosure only | No | Too late; customer already paid |
| Checkout page disclosure (online) | Yes | Must appear before payment submission |
| Confirmation email disclosure | No | Too late; transaction already completed |
| Verbal disclosure at register | Insufficient alone | Must be written/posted |
The practical risk of poor disclosure is not just a card network complaint. In states with consumer protection statutes that apply to undisclosed fees, a post-transaction surcharge can be characterized as a deceptive trade practice subject to state AG enforcement and private consumer lawsuits.
Credit Card Fee Law for Businesses
Credit card fee law for businesses in 2026 is governed by three overlapping legal frameworks: card network merchant agreements (Visa and Mastercard rules), state consumer protection statutes, and federal law (primarily the Truth in Lending Act provisions relating to disclosure).
Businesses that accept Visa or Mastercard are bound by those networks’ merchant rules as a condition of card acceptance. These rules function as private contract law. Violating them does not result in criminal prosecution. It results in financial penalties from the card network and potential termination of the merchant’s ability to accept those cards.
State law operates on top of the card network rules. In ban states (Connecticut, Massachusetts), the state law creates an independent legal prohibition with its own enforcement mechanism. In other states, consumer protection laws still apply to how surcharges are disclosed and structured, even where surcharging is generally permitted.
Federal law applies primarily through the Truth in Lending Act (15 U.S.C. 1601 et seq.) and its implementing regulations. The TILA requires clear disclosure of credit card costs to consumers. While TILA focuses primarily on lenders rather than merchants, its disclosure principles inform how regulators interpret merchant surcharge transparency obligations.
Business compliance checklist for 2026:
- Confirm your state is not a surcharge-ban state
- Notify Visa and Mastercard at least 30 days before surcharging
- Determine your actual merchant discount rate
- Set surcharge at or below 3% or your actual rate (whichever is lower)
- Post disclosure at store entrance and payment terminal
- Apply surcharge only to credit cards, never to debit cards
- Itemize surcharge as a separate line on every receipt
- Do not charge different surcharge rates for different credit card brands (Visa vs. Mastercard, for example, must be treated the same within each network)
Credit Card Surcharge Laws by State
Credit card surcharge laws vary by state, with the majority of states now permitting surcharging subject to disclosure requirements and the federal cap. The post-2017 legal environment has dramatically shifted from widespread prohibition to widespread permission.
Here is a state-by-state overview of credit card surcharge status as of 2026:
| State | Surcharging Permitted | Key Statute or Basis | Notes |
|---|---|---|---|
| California | Yes | Civil Code 1748.1 (amended) | Permitted with dual pricing disclosure |
| New York | Yes | GBL 518 (post-2017 interpretation) | Must show both cash and card prices |
| Texas | Yes | Finance Code 339.001 | Permitted with proper disclosure |
| Florida | Yes | Statute 501.0117 (amended) | Permitted with disclosure |
| Connecticut | No | Conn. Gen. Stat. 42-133ff | Outright ban still in effect |
| Massachusetts | No | M.G.L. c. 140D s. 28A | Outright ban still in effect |
| Colorado | Yes | HB 22-1282 (2022) | Explicitly authorized surcharging |
| Ohio | Yes | No specific statute | Governed by card network rules |
The two states where surcharging remains banned (Connecticut and Massachusetts) have maintained their statutes despite court challenges. Merchants operating in those states cannot add a credit card surcharge even if they notify card networks and follow all other rules. The state law prohibition is independently enforceable regardless of card network permissions.
Colorado’s 2022 legislation (HB 22-1282) is notable because it explicitly authorized credit card surcharging while capping it at the merchant’s actual processing cost or 2%, whichever is lower. Colorado’s state cap is stricter than the card network cap of 3%.
States Where Credit Card Surcharges Are Banned
Credit card surcharges are banned by state law in Connecticut and Massachusetts as of 2026. These are the only two U.S. states that still maintain outright statutory prohibitions on merchants charging customers extra for using a credit card.
Both states have maintained their bans despite the broader legal and regulatory trend toward permitting surcharging. Merchants operating in these states cannot legally add a credit card fee to transactions even if they are otherwise compliant with card network rules and federal requirements.
The legal basis for each state’s ban:
- Connecticut: Connecticut General Statutes Section 42-133ff prohibits merchants from imposing a surcharge on customers who pay by credit card. The statute applies to all sellers of goods and services and carries civil penalty exposure.
- Massachusetts: Massachusetts General Laws Chapter 140D Section 28A mirrors the federal Truth in Lending Act’s historical surcharge prohibition. It has been interpreted to ban merchant-level credit card surcharges on consumer transactions.
Merchants in Connecticut and Massachusetts who charge credit card surcharges face civil penalties enforced by state attorneys general. Specific penalty amounts vary by case, but enforcement actions have resulted in fines and mandatory restitution to affected customers.
Several other states previously had surcharge bans that have since been repealed or effectively eliminated through court interpretation. The states where bans were previously active but are now largely resolved include California (statutory language remains but has been reinterpreted), New York (post-2017 compliance through dual pricing), Florida, and Kansas.
Merchants with locations in multiple states must apply different pricing policies in ban states versus permitted states. Operating the same surcharge policy across all locations without accounting for state variation is one of the most common compliance errors.
Key Takeaway: Only Connecticut and Massachusetts ban credit card surcharges outright in 2026. Merchants in all other states can surcharge credit card transactions if they comply with card network rules, state disclosure requirements, and the 3% cap.
Can Small Businesses Charge Credit Card Fees
Yes, small businesses can charge credit card fees to customers in 48 states, and the rules that apply to small businesses are identical to those that apply to large retailers. Card network rules and state laws do not create an exemption or special treatment based on business size.
The practical difference for small businesses is that they often have less access to compliance guidance and may be unaware of all the notification and disclosure requirements that apply. A small restaurant owner who adds a 3.5% surcharge without notifying Visa and Mastercard is violating the merchant agreement just as clearly as a large chain would be.
Small businesses are also more likely to set their surcharge based on what they think they pay for processing rather than their actual documented merchant discount rate. Processors bundle various fees into statements that can be difficult to read. The actual effective rate might be lower than the flat percentage the merchant assumes, which means their surcharge may be set too high.
Steps small businesses should take before implementing surcharging:
- Review your merchant processing statement to identify your actual effective merchant discount rate
- Contact your payment processor to confirm the exact rate applicable to credit card transactions
- Notify Visa and Mastercard through your processor or directly at least 30 days in advance
- Order or create compliant point-of-entry and point-of-sale signage
- Update your POS system to apply the surcharge only to credit card transactions, not debit
- Train staff to explain the surcharge to customers who ask
Small business processors like Square, Stripe, Toast, and Clover all offer surcharging features that automate the compliance requirements once properly configured. Using these built-in features reduces (but does not eliminate) the risk of technical compliance errors.
Visa Mastercard Surcharge Rules 2026
Visa and Mastercard surcharge rules were significantly updated following the 2023 merchant settlement agreement, and those updated rules remain in effect in 2026. The most important change from the settlement was the reduction of the maximum surcharge cap from 4% to 3%.
The 2023 settlement resolved a long-running class action lawsuit by merchants who argued that Visa and Mastercard’s anti-surcharge rules and fee-setting practices violated antitrust law. As part of the settlement, the networks agreed to reduce their surcharge caps and provide merchants with more flexibility in steering customers to lower-cost payment methods.
Current Visa and Mastercard surcharge rules as of 2026:
| Rule Element | Requirement | Effective Since |
|---|---|---|
| Maximum surcharge percentage | 3% or actual cost, whichever is lower | April 2023 |
| Notification requirement | 30 days advance notice to card network | Ongoing |
| Debit card surcharging | Prohibited | Ongoing |
| Disclosure at point of entry | Required, posted signage | Ongoing |
| Disclosure at point of sale | Required, terminal display | Ongoing |
| Receipt itemization | Surcharge must be separate line item | Ongoing |
| Brand-level consistency | Same rate for all cards of same network | Ongoing |
The 3% cap means that even if a merchant’s actual processing cost is 3.5%, they cannot charge more than 3%. The cap applies to the total surcharge on any single transaction regardless of the merchant’s cost structure.
Merchants who were charging 4% before the settlement and never updated their surcharge settings are currently in violation of card network rules. The card networks periodically audit merchant surcharge practices, and non-compliant merchants face warnings, fines, and in repeat cases, termination of card acceptance rights.
Maximum Credit Card Surcharge Allowed
The maximum credit card surcharge allowed in 2026 is 3% of the transaction value, or the merchant’s actual cost of acceptance, whichever is lower. This cap was set by the Visa and Mastercard settlement agreement that took effect in April 2023 and replaced the previous 4% cap.
The “or actual cost, whichever is lower” component is the part most merchants ignore. If your payment processor charges you an effective rate of 2.1% on Visa credit card transactions, your maximum legal surcharge for Visa transactions is 2.1%, not 3%. Charging 3% when your actual cost is 2.1% means you are profiting from the surcharge, which violates the rule that surcharges are cost-recovery mechanisms, not revenue sources.
Calculating the correct maximum surcharge:
- Step 1: Obtain your merchant statement showing interchange fees, processor markup, and any per-transaction fees
- Step 2: Calculate your effective rate by dividing total credit card processing costs by total credit card sales volume
- Step 3: Compare your effective rate to 3%
- Step 4: Set your surcharge at the lower of the two numbers
- Step 5: Review and recalculate at least annually as processor rates change
The most common mistake is setting a flat 3% surcharge without verifying that 3% does not exceed actual processing costs. For merchants with negotiated low rates or who process primarily premium rewards cards at higher interchange, the actual rate calculation may produce a number different from what the processor advertises.
Some states impose lower caps than the card network’s 3% cap. Colorado, for example, caps surcharges at the lower of actual cost or 2%. Merchants in those states must comply with the stricter state cap regardless of what the card network allows.
Credit Card Surcharge Disclosure Requirements
Credit card surcharge disclosure requirements are set by card network rules and, in some states, by state law. Both Visa and Mastercard require merchants to make surcharge disclosures in two specific locations before every transaction: at the point of entry and at the point of sale.
The point-of-entry disclosure means that any customer who enters your physical business location must be informed of the surcharge before they select products or services. For a retail store, this is a sign posted at the entrance or at a highly visible location near the front of the store. For a restaurant, it means a disclosure on the menu or at the host stand.
The point-of-sale disclosure means that the customer must be informed of the specific surcharge amount before they approve the transaction at the payment terminal. Simply having an entrance sign is not sufficient if the payment terminal does not separately display the surcharge amount before the customer approves payment.
For online merchants, the disclosure must appear on the checkout page before the customer clicks the final payment confirmation button. A disclosure buried in the terms of service or appearing only on the post-payment confirmation screen does not satisfy the requirement.
Specific disclosure requirements:
- Physical signage at store entrance stating that a surcharge applies to credit card transactions
- Terminal display showing the surcharge amount before transaction approval
- Separate surcharge line item on printed or digital receipt
- Disclosure must specify that the surcharge does not apply to debit cards
- Disclosure must identify the surcharge as a surcharge (not rebranded as a “service fee” or “convenience charge” in contexts where those terms have specific separate meanings)
Some state laws add requirements beyond the card network rules. New York’s General Business Law 518, as interpreted after the Expressions Hair Design case, requires that merchants who charge different prices for cash and card must display both prices clearly wherever prices are shown.
Key Takeaway: Surcharge disclosure must happen at two specific points: when the customer enters the business and when they approve payment at the terminal. Disclosure only on the receipt is too late and violates both card network rules and state consumer protection laws in many states.
How Much Can a Merchant Charge for Credit Card Fee
A merchant can charge a maximum of 3% for a credit card fee as of 2026, subject to the additional requirement that the surcharge cannot exceed the merchant’s actual cost of acceptance. The 3% cap applies per transaction and is set by the updated Visa and Mastercard merchant rules following the 2023 settlement.
The practical range of credit card surcharges that merchants actually implement runs from about 1.5% to 3%. Merchants with high-volume, low-margin businesses tend to set surcharges closer to their actual cost (often 2% to 2.5%). Merchants in industries with traditionally high card acceptance rates (restaurants, retail) sometimes set the full 3%.
Industry context for typical surcharge rates:
| Industry | Typical Processing Cost | Common Surcharge Set | Within Legal Limit |
|---|---|---|---|
| Restaurant | 2.2% to 2.8% | 3% | Only if actual cost is 3% |
| Retail | 1.9% to 2.5% | 2% to 3% | Varies |
| Professional services | 2.5% to 3.5% | 3% | Yes if capped correctly |
| Healthcare | 2% to 3% | 2% to 3% | Varies |
| E-commerce | 2.2% to 3.5% | 2% to 3% | Varies |
Merchants who use payment processors with flat-rate pricing (like Square at 2.6% + 10 cents) may find that their effective rate fluctuates by transaction size, making it difficult to set a single surcharge percentage that is always compliant. In those cases, setting the surcharge at the processor’s advertised flat rate (2.6% in the Square example) is a reasonable proxy, though merchants should confirm with their processor.
Is It Legal to Charge a 3 Percent Credit Card Fee
Yes, charging a 3% credit card fee is legal in 48 states as of 2026, provided the merchant’s actual credit card processing cost is at or above 3% and all card network notification and disclosure requirements have been satisfied. In states with lower state-imposed caps, 3% may exceed the state limit.
The 3% figure has become the de facto standard surcharge rate adopted by many businesses because it aligns with the card network cap. This creates a widespread assumption that 3% is always legal everywhere. That assumption is wrong in two important ways.
First, 3% is not legal if your actual processing cost is below 3%. A merchant paying 2.3% in processing fees cannot charge 3% because the surcharge would then exceed the cost of acceptance. The 3% is a ceiling, not an automatic entitlement.
Second, some states impose lower caps:
| State | State Surcharge Cap | Card Network Cap | Effective Maximum |
|---|---|---|---|
| Colorado | Lower of actual cost or 2% | 3% | 2% |
| Connecticut | Banned entirely | 3% | 0% (banned) |
| Massachusetts | Banned entirely | 3% | 0% (banned) |
| All other states | No specific state cap | 3% | 3% (if actual cost allows) |
A merchant in Colorado who charges 3% is violating Colorado’s state law even though they are within the card network cap. Colorado HB 22-1282 imposes a stricter state standard that cannot be overridden by card network rules.
For merchants in the 45 or so states with no specific state cap and whose actual processing cost is at or above 3%, charging exactly 3% is legally compliant. Charging above 3% is a violation of card network rules regardless of state.
Cash Discount vs Credit Card Surcharge
A cash discount and a credit card surcharge are two fundamentally different pricing structures that produce similar outcomes for customers but are treated very differently under card network rules and state law. Understanding the distinction is essential for merchants who want to legally recover their processing costs.
A cash discount program sets the credit card price as the standard price and offers customers who pay with cash a discount from that price. The card price is the starting point. Cash customers pay less. This structure is explicitly permitted under card network rules and all state laws because it rewards cash use rather than penalizing card use.
A credit card surcharge sets the cash price as the standard price and adds a fee for customers who pay with a credit card. The cash price is the starting point. Card customers pay more. This structure is the one that is regulated by card network rules (requiring notification, disclosure, and caps) and banned in Connecticut and Massachusetts.
| Feature | Cash Discount | Credit Card Surcharge |
|---|---|---|
| Baseline price | Card price (higher) | Cash price (lower) |
| Who pays standard price | Card users | Cash users |
| Permitted in all states | Yes | No (banned in CT and MA) |
| Card network notification required | No | Yes (30 days) |
| Maximum amount | No cap | 3% or actual cost |
| Disclosure requirements | Dual pricing display | Point-of-entry and POS |
| Debit card impact | Debit gets same discount | Cannot apply to debit |
The economic outcome can be identical. A store charging $100 for card and $97 for cash looks the same whether it is called a cash discount or a surcharge. But the regulatory treatment is entirely different. Merchants in Connecticut and Massachusetts who want to recover processing costs legally must use the cash discount structure. Merchants elsewhere have both options.
Penalty for Illegal Credit Card Surcharge
The penalties for charging an illegal credit card surcharge come from three sources: card network enforcement, state civil penalties, and potential FTC or state AG action. The consequences range from fines and warnings to loss of card acceptance rights and significant civil liability.
Card network penalties are the most immediate consequence for most merchants. Visa and Mastercard both have compliance enforcement teams that investigate merchant surcharge violations. Documented violations can result in:
- Warning letters with required corrective action deadlines
- Financial penalties ranging from $5,000 to $25,000 or more per violation period
- Placement on the card network’s monitoring program
- Termination of the ability to accept that card brand
State civil penalties vary significantly by jurisdiction:
| State | Enforcement Authority | Penalty Range | Private Right of Action |
|---|---|---|---|
| Connecticut | AG Consumer Protection | Civil penalties, injunctive relief | Yes, per violation |
| Massachusetts | AG Consumer Protection | Civil penalties, restitution | Yes |
| Colorado | AG, DORA | Up to $20,000 per violation | Yes (CCPA) |
| California | AG, private plaintiff | UCL restitution + civil penalties | Yes |
| New York | AG | Civil penalty up to $500 per violation | Yes |
FTC enforcement applies when surcharge practices constitute deceptive trade practices under Section 5 of the FTC Act. The FTC has pursued merchants for undisclosed or misleading surcharge practices, and civil penalties for violating FTC orders can exceed $50,000 per day.
The combined exposure from card network penalties, state civil enforcement, and consumer litigation can reach six figures for merchants with systematic surcharging violations. The per-transaction nature of many penalty structures means that high-volume merchants face particularly steep exposure.
Consumer Rights When Charged Credit Card Fee
Consumers who are charged an illegal or improperly disclosed credit card surcharge have specific rights under card network rules, state consumer protection law, and in some cases federal law. These rights include the right to dispute the charge, report the merchant, and in some states, sue for damages.
The most immediate consumer right is to dispute the transaction with the card issuer. If a merchant added an undisclosed surcharge or charged a surcharge in a state where it is banned, the consumer can contact their credit card company and request a chargeback for the unauthorized amount. The card issuer will investigate and may reverse the surcharge.
Beyond the card issuer dispute, consumers have four main reporting channels:
- File a complaint with Visa or Mastercard through your card issuer (ask them to escalate to network compliance)
- File a consumer complaint with the FTC at ReportFraud.ftc.gov
- File a complaint with your state attorney general’s consumer protection division
- In states with private rights of action, file a small claims court case to recover the surcharge amount plus potentially additional statutory damages
In Massachusetts and Connecticut, where surcharges are banned entirely, every surcharge charged is a per-violation offense. Consumers in those states have the strongest position for both state AG complaints and private lawsuits.
Consumers who are charged a surcharge exceeding 3% have grounds for complaints even in states where surcharging is generally legal. The cap violation is enforceable regardless of whether the state has its own surcharge law.
How to Report Illegal Credit Card Surcharge
Reporting an illegal credit card surcharge involves four potential channels, and the most effective approach is to use multiple channels simultaneously to create documented enforcement pressure on the merchant.
Before filing any complaint, document the violation thoroughly:
- Keep the receipt showing the surcharge as a separate line item
- Photograph any posted signage (or note the absence of required signage)
- Note the merchant name, address, date, and amount of the surcharge
- Note the card type used and whether the receipt identified it as a credit or debit transaction
- Record whether you were informed of the surcharge before or after completing the transaction
The four reporting channels and what each covers:
| Channel | What to Report | Expected Outcome |
|---|---|---|
| Visa/Mastercard via card issuer | Surcharge on debit, over 3% cap, no disclosure | Network investigation, possible merchant penalty |
| FTC ReportFraud.ftc.gov | Undisclosed fees, deceptive pricing | Complaint logged, may contribute to enforcement action |
| State Attorney General | State surcharge ban violation, deceptive practice | State investigation, possible civil penalty against merchant |
| CFPB | If bank-issued card is involved in a fee dispute | Complaint investigation |
For consumers in Connecticut and Massachusetts, a state AG complaint is the strongest option because the state ban creates clear legal grounds for enforcement action. For consumers in other states, the card network complaint is often more effective because it triggers a contract-based enforcement process that the merchant cannot simply ignore.
Small claims court remains an option in states where the surcharge ban or consumer protection statute creates a private right of action. Filing fees are typically $30 to $100, the process does not require a lawyer, and courts can award the surcharge amount plus statutory damages in some states.
Key Takeaway: Consumers have four reporting channels for illegal credit card surcharges: the card network, the FTC, the state attorney general, and in many states, small claims court for direct recovery. Using multiple channels creates the most enforcement pressure.
Frequently Asked Questions
Is it legal for merchants to charge customers a credit card processing fee?
Yes, it is legal in 48 U.S. states, provided the merchant notifies Visa and Mastercard 30 days in advance, caps the fee at 3% or actual cost (whichever is lower), and discloses the surcharge before the transaction.
Connecticut and Massachusetts are the only states where credit card surcharges remain banned outright.
Merchants who surcharge without following these steps violate their merchant agreement and may face card network penalties.
What states ban credit card surcharges entirely?
Connecticut and Massachusetts are the only two states that ban credit card surcharges for consumer transactions as of 2026.
Both states maintain statutory prohibitions that are independently enforceable by state attorneys general.
Merchants in these states cannot legally add a credit card fee even if they comply with all card network requirements.
How much can a merchant legally charge as a credit card surcharge?
The maximum credit card surcharge is 3% of the transaction value under current Visa and Mastercard rules, but it cannot exceed the merchant’s actual processing cost.
Colorado imposes a stricter state cap of 2% or actual cost, whichever is lower.
Merchants who charge more than 3% violate card network rules regardless of their state’s laws.
What is the difference between a credit card surcharge and a cash discount?
A credit card surcharge adds a fee on top of the cash price because the customer used a credit card.
A cash discount program sets the card price as the standard price and gives a reduction to customers who pay with cash.
Cash discounts are legal everywhere and require no card network notification; surcharges require 30-day notification, a 3% cap, and are banned in two states.
What can I do if a merchant charges me an illegal credit card surcharge?
Contact your credit card issuer and dispute the surcharge amount as an unauthorized charge.
File a complaint with Visa or Mastercard through your card issuer and report the merchant to the FTC and your state attorney general.
In states with surcharge bans or consumer protection private rights of action, you can file a small claims court case to recover the surcharge and potentially additional damages.
The rules around passing credit card fees to customers are specific, enforceable, and changing. Merchants who stay current with the 3% cap, the two-state bans, and the disclosure requirements can legally recover their processing costs. Consumers who understand these rules can identify and report violations effectively.
