Yes, it is legal to charge a credit card fee in most U.S. states. Merchants can add a surcharge to cover their processing costs when you pay with plastic. But here’s the catch: two states still ban these fees outright, and every state has rules about how much merchants can charge.
About 85% of American businesses now accept credit cards. Processing those payments costs them between 1.5% and 3.5% per transaction. Many merchants pass that cost directly to you through surcharges.
The laws changed dramatically after a 2013 class action settlement against Visa and Mastercard. Before that, surcharges were banned everywhere. Now the rules vary wildly depending on where you live.
This guide breaks down every state’s rules for 2026, explains the maximum fees allowed, and tells you exactly what to do if a business charges you illegally. You’ll learn the difference between surcharges and cash discounts, which states still prohibit these fees, and how to protect yourself as a consumer.
Is It Legal to Charge a Credit Card Fee
Yes, charging a credit card fee is legal in 48 states as of 2026. Federal law does not prohibit merchants from adding surcharges to credit card transactions, leaving regulation up to individual states.
The legality traces back to a 2013 settlement in a class action lawsuit against Visa and Mastercard. Merchants sued the card networks, arguing that no-surcharge rules violated antitrust laws. The settlement lifted the blanket ban and allowed merchants to pass processing costs to customers.
Two states currently maintain complete bans on credit card surcharges: Connecticut and Massachusetts. If you’re shopping in either state, merchants cannot legally add any fee for credit card use.
In the remaining 48 states, merchants must follow specific rules. They must disclose the surcharge before you complete the transaction. The fee cannot exceed their actual processing cost or the cap set by card networks, whichever is lower.
| Legal Status | States | Key Rule |
|---|---|---|
| Fully Legal | 48 states | Must disclose fee, cap at 3% or actual cost |
| Completely Banned | Connecticut, Massachusetts | No surcharges allowed under any circumstance |
Merchants who violate these rules face penalties. State attorneys general can pursue civil actions, and consumers may have grounds for complaints under state consumer protection laws.
Is It Illegal to Charge a Credit Card Fee
It is illegal to charge a credit card fee only in Connecticut and Massachusetts. These two states have maintained surcharge bans even after the 2013 settlement opened the door elsewhere.
Connecticut General Statutes Section 42-133ff explicitly prohibits merchants from imposing surcharges on credit card transactions. Violations can result in civil penalties and enforcement actions by the state attorney general.
Massachusetts General Laws Chapter 140D, Section 28A contains a similar prohibition. The law makes it unlawful for any seller to impose a surcharge on a buyer who pays by credit card rather than cash or check.
In all other states, credit card fees are legal when merchants follow the rules. The fee must be disclosed at the point of entry (usually a sign at the door) and again at the point of sale before the transaction completes.
Breaking the disclosure rules can make an otherwise legal surcharge illegal. A merchant in Texas who springs a 3% fee on you without warning has violated state consumer protection laws, even though Texas allows surcharges.
The distinction matters for consumers. If you see a fee at checkout in Connecticut, you’re witnessing a violation. If you see the same fee in Florida with proper signage, it’s perfectly legal.
Is It Against the Law to Charge a Credit Card Fee
Charging a credit card fee is against the law only when merchants violate state-specific rules. The activity itself is legal in most places, but the execution determines legality.
The law requires three things for a surcharge to be legal: proper disclosure, reasonable amount, and compliance with state regulations. Missing any element can turn a legal fee into an illegal one.
Disclosure violations occur when merchants fail to post signage at store entrances or don’t inform customers before completing transactions. Many states require both visual signage and verbal or printed notification at checkout.
Amount violations happen when surcharges exceed legal caps. Charging 5% when the cap is 3% breaks the law even in states that allow surcharges.
Location violations occur when merchants charge fees in Connecticut or Massachusetts, where all surcharges remain illegal regardless of amount or disclosure.
| Violation Type | Example | Potential Consequence |
|---|---|---|
| Disclosure Failure | No warning before checkout | State consumer protection violation |
| Excessive Amount | 4% fee where 3% cap applies | Civil penalties, refund orders |
| Wrong State | Any surcharge in CT or MA | Criminal or civil enforcement |
Consumers who encounter violations have options. Filing complaints with state attorneys general is the most direct path to enforcement.
Key Takeaway: Credit card fees are legal in 48 states but become illegal when merchants skip disclosures, exceed caps, or operate in Connecticut or Massachusetts.
What States Is It Illegal to Charge Credit Card Fee
It is illegal to charge a credit card fee in Connecticut and Massachusetts only. These are the two remaining states with outright bans on credit card surcharges as of 2026.
Both states maintained their bans despite the 2013 settlement that opened surcharging nationwide. Their legislatures chose to keep consumer protection laws that treat surcharges as deceptive practices.
Connecticut’s ban appears in Section 42-133ff of the General Statutes. The law prohibits any seller from imposing a surcharge on a cardholder who elects to use a credit card. There are no exceptions for disclosure or small amounts.
Massachusetts relies on Chapter 140D, Section 28A. This statute similarly bars all surcharges, treating them as an unfair business practice regardless of the merchant’s processing costs.
Several states previously had bans but repealed them:
- California’s ban was struck down as unconstitutional in 2015
- New York’s ban was invalidated by federal courts in 2017
- Texas repealed its ban in 2013
- Florida lifted its prohibition in 2010
- Kansas ended its ban after the 2013 settlement
Colorado previously had restrictions but now allows surcharges with proper disclosure. Oklahoma, Maine, and other states that once limited surcharges have also opened their markets.
If you live in Connecticut or Massachusetts, any credit card surcharge you encounter is illegal. You have grounds to file a complaint with your state attorney general.
States That Ban Credit Card Surcharges
Only two states ban credit card surcharges in 2026: Connecticut and Massachusetts. Every other state permits surcharges under varying conditions.
The landscape has shifted dramatically over the past decade. Ten years ago, roughly a dozen states prohibited these fees. Legal challenges and legislative changes have whittled that number down to just two holdouts.
Connecticut enforces its ban through the Department of Consumer Protection. Merchants caught charging surcharges face civil penalties and potential license issues for repeat violations.
Massachusetts empowers its Attorney General to pursue enforcement. The state treats surcharge violations as potential violations of consumer protection statutes, opening merchants to significant civil liability.
Here’s how states currently break down:
| Category | Number of States | Examples |
|---|---|---|
| Complete Ban | 2 | Connecticut, Massachusetts |
| Legal with Disclosure | 48 | Texas, New York, California, Florida |
| Legal with Caps | 48 | All non-ban states have 3% or actual cost cap |
Some states considered reinstating bans in recent legislative sessions. Colorado introduced a bill in 2024 to prohibit surcharges, but it failed to pass. Similar efforts in other states have not gained traction.
The trend favors allowing surcharges rather than banning them. Consumer groups continue to push for restrictions, but business interests have largely prevailed in state legislatures.
Is It Legal to Charge a Credit Card Fee in Texas
Yes, charging a credit card fee is completely legal in Texas. The state repealed its surcharge ban in 2013, and merchants can now add fees for credit card transactions.
Texas law requires merchants to follow specific disclosure rules. They must post clear signage at the entrance to their business and notify customers of the fee before completing the transaction. The sign must state the surcharge amount or percentage clearly.
The maximum surcharge allowed in Texas is capped at 3% or the merchant’s actual processing cost, whichever is lower. Most Texas businesses charge between 2% and 3% when they impose surcharges.
Texas business owners must also register their surcharging program with Visa and Mastercard if they use those networks. This registration requirement comes from the card networks, not state law, but failure to comply can result in losing the ability to accept cards.
Common Texas surcharge scenarios:
- Gas stations offering cash discounts (legal alternative to surcharges)
- Small retailers adding 2.5% to credit purchases
- Service businesses building fees into credit card invoices
- Restaurants adding surcharges at the point of sale
The Texas Attorney General’s office handles complaints about improper surcharging. Merchants who fail to disclose fees properly can face action under the Texas Deceptive Trade Practices Act. Penalties include civil fines and potentially treble damages in consumer lawsuits.
Key Takeaway: Texas fully allows credit card surcharges when merchants disclose them properly and keep fees at or below 3%.
Is It Legal to Charge a Credit Card Fee in NY
Yes, charging a credit card fee is legal in New York as of 2026. The state’s previous ban was struck down by federal courts, and merchants can now impose surcharges with proper disclosure.
New York’s surcharge ban faced a constitutional challenge in 2017. The Second Circuit Court of Appeals ruled that the state’s prohibition on surcharges violated the First Amendment by restricting how merchants communicate prices. The U.S. Supreme Court sent the case back for further review, and the ban effectively ended.
New York merchants must follow strict disclosure requirements. The surcharge must be posted at the store entrance and displayed at the point of sale. Customers must know about the fee before they hand over their card.
The 3% cap applies in New York just as in other states. Merchants cannot charge more than their actual processing costs or the card network maximum. Many New York businesses choose not to surcharge because of the state’s consumer-friendly reputation and competitive retail environment.
New York’s Department of State oversees business practices. Consumers who encounter undisclosed surcharges can file complaints through the state’s consumer protection division.
The change has been particularly noticeable in New York City. Small businesses, restaurants, and service providers increasingly add fees to offset high processing costs in the competitive urban market.
Credit Card Surcharge California Law
California allows credit card surcharges after a 2015 federal court ruling struck down the state’s ban. Merchants can charge fees for credit card transactions as long as they follow disclosure rules.
California’s original ban, found in Civil Code Section 1748.1, was ruled unconstitutional in the case Italian Colors Restaurant v. Harris. The Ninth Circuit Court found that the law violated the First Amendment by regulating how businesses communicate prices.
The state still requires robust disclosure. California merchants must clearly post surcharge information at store entrances and at checkout. The notification must include the specific percentage or dollar amount of the fee.
California’s 3% cap matches the card network maximum. Merchants cannot exceed their actual processing costs or 3%, whichever is lower. The California Attorney General can pursue merchants who violate these limits.
| California Surcharge Rule | Requirement |
|---|---|
| Maximum Fee | 3% or actual cost (lower of two) |
| Entrance Disclosure | Required |
| Point of Sale Disclosure | Required |
| Debit Card Surcharges | Prohibited |
| Enforcement Agency | CA Attorney General |
California explicitly prohibits surcharges on debit cards. This distinction matters because many consumers use debit cards thinking they’re avoiding the fee, and merchants must honor that expectation.
The Los Angeles and San Francisco areas have seen widespread adoption of surcharging, especially among small businesses facing high rents and operating costs.
Is It Legal to Charge a 3 Credit Card Fee
Yes, a 3% credit card fee is legal in most states. This percentage represents the maximum cap allowed by major card networks and serves as the standard ceiling for surcharges nationwide.
The 3% limit comes from Visa and Mastercard rules, not federal law. When merchants sign agreements to accept these cards, they agree to cap surcharges at 3% or their actual processing cost, whichever is lower.
Most merchants pay between 1.5% and 3.5% in processing fees depending on their size, industry, and card types accepted. A 3% surcharge often covers their costs entirely, which is why this number appears so frequently.
In states that allow surcharges, 3% is perfectly legal when properly disclosed. Merchants must post signage and inform customers before checkout. The fee cannot exceed the merchant’s actual cost even if that cost is below 3%.
When 3% becomes illegal:
- In Connecticut or Massachusetts (all surcharges banned)
- When the merchant’s actual cost is lower (say 2.2%) but they charge 3%
- When proper disclosure doesn’t happen
- When applied to debit card transactions (prohibited by most card networks)
Some merchants round down to 2.5% or 2.75% to avoid any question about exceeding their actual costs. This practice protects them from consumer complaints and potential enforcement actions.
Key Takeaway: A 3% credit card fee is legal in 48 states when properly disclosed and when it doesn’t exceed the merchant’s actual processing costs.
Maximum Credit Card Surcharge Allowed
The maximum credit card surcharge allowed is 3% in most states that permit surcharging. This cap comes from card network rules rather than federal law, but states incorporate it into their consumer protection frameworks.
Visa and Mastercard both set 3% as the ceiling in their merchant agreements. Discover allows up to 3%, and American Express permits surcharges equal to those charged on other card types. These network rules create a de facto national standard.
Some important details about the cap:
| Card Network | Maximum Surcharge | Special Rules |
|---|---|---|
| Visa | 3% or actual cost | Must register surcharge program |
| Mastercard | 3% or actual cost | 30-day notification required |
| Discover | 3% or actual cost | Must match other card surcharges |
| American Express | Match other cards | Cannot exceed Visa/MC surcharge |
The “actual cost” rule matters more than the 3% ceiling for many merchants. If a business pays only 2.1% in processing fees, they cannot legally charge 3%. The surcharge must reflect real costs.
Merchants who exceed these limits face consequences from two directions. Card networks can terminate their merchant accounts, effectively ending their ability to accept cards. State attorneys general can pursue civil enforcement for consumer protection violations.
Consumers should watch for fees above 3%. Any surcharge exceeding this threshold is likely illegal and worth reporting.
Is It Legal to Charge a Credit Card Processing Fee
Yes, charging a credit card processing fee is legal in 48 states when the fee represents actual costs and follows disclosure rules. “Processing fee” is essentially another term for credit card surcharge.
Some merchants use “processing fee” instead of “surcharge” because it sounds more neutral. The legal rules are identical regardless of what the fee is called. Disclosure requirements, caps, and state restrictions apply the same way.
The key legal requirement is accuracy. If a merchant calls it a “processing fee,” the amount must actually reflect processing costs. Charging a 3% “processing fee” when actual costs run 1.8% could constitute deception under consumer protection laws.
Government agencies often charge “convenience fees” rather than processing fees. This distinction matters legally. Convenience fees can only be charged when offering an alternative payment channel, like paying online instead of in person. Processing fees can apply to all credit card transactions.
Common places you’ll see processing fees:
- Medical offices and healthcare providers
- Professional service firms (lawyers, accountants)
- Contractors and home service businesses
- Small retail shops
- Online ticketing platforms
The Federal Trade Commission monitors deceptive fee practices. Merchants who misrepresent fees or hide them until checkout may face FTC enforcement in addition to state-level consequences.
Credit Card Fee vs Cash Discount
A credit card fee adds cost to card purchases, while a cash discount reduces the price for cash payments. Both achieve similar results for merchants, but the legal framework differs significantly.
Credit card surcharges are fees added to the listed price when you pay by card. If an item is marked $100 and there’s a 3% surcharge, you pay $103 with a credit card. The listed price is the “base” price.
Cash discounts work in reverse. The listed price already includes the credit card cost. If an item is marked $103 and there’s a 3% cash discount, you pay $100 with cash. The inflated price is the “base” price.
| Feature | Credit Card Surcharge | Cash Discount |
|---|---|---|
| Price Effect | Adds to marked price | Reduces from marked price |
| Legal in CT/MA | No | Yes |
| Disclosure Needed | Yes, specific rules | Yes, must show both prices |
| Customer Perception | Negative (feels like penalty) | Positive (feels like reward) |
| Card Network Rules | Must register, follow caps | No registration needed |
Cash discounts are legal everywhere, including Connecticut and Massachusetts. This loophole explains why some merchants in ban states offer cash discounts rather than surcharges. The economic effect is identical, but the legal treatment differs.
Many merchants prefer cash discounts because customers respond better psychologically. Getting a discount feels like a reward, while paying a surcharge feels like a penalty.
Key Takeaway: Cash discounts and credit card fees achieve the same result, but discounts are legal everywhere while surcharges remain banned in two states.
Can Merchants Charge Credit Card Fees
Yes, merchants can charge credit card fees in 48 states after meeting disclosure requirements and staying within fee caps. The 2013 settlement against Visa and Mastercard opened this practice nationwide.
Before 2013, card network rules prohibited all surcharges. Merchants who wanted to discourage card use had no legal option to pass costs directly to customers. The class action settlement changed everything.
Now merchants must follow a process to charge legally:
Step 1: Check state law. If operating in Connecticut or Massachusetts, surcharges remain illegal.
Step 2: Register with card networks. Visa requires merchants to register their surcharging program 30 days before implementation.
Step 3: Post disclosures. Signage at the entrance and point of sale must clearly state the surcharge amount.
Step 4: Calculate actual costs. The surcharge cannot exceed real processing expenses or 3%, whichever is lower.
Step 5: Apply consistently. Surcharges must apply to all credit card brands accepted, not just some.
Small businesses benefit most from surcharging. Large retailers like Walmart and Target rarely impose fees because they negotiate lower processing rates and want to maintain customer satisfaction. Local shops, restaurants, and service providers more commonly pass costs through.
Some industries have embraced surcharging heavily. Gas stations pioneered cash vs. credit pricing decades ago. Medical offices, contractors, and professional service firms have increasingly added fees in recent years.
How to Report Illegal Credit Card Surcharge
Report an illegal credit card surcharge by filing a complaint with your state attorney general or consumer protection agency. These offices have authority to investigate businesses and impose penalties.
Start by documenting the violation. Keep your receipt showing the surcharge amount. Take photos of any signage (or lack thereof) at the business. Note the date, location, and any statements made by staff about the fee.
Where to file complaints:
| Type of Violation | Where to Report |
|---|---|
| Missing disclosure | State Attorney General |
| Excessive fee (over 3%) | State Attorney General + card network |
| Any surcharge in CT or MA | State consumer protection office |
| Debit card surcharge | Card network (Visa, Mastercard) |
| Deceptive fee practices | Federal Trade Commission |
Contact Visa or Mastercard directly if a merchant violates network rules. Both companies have merchant compliance departments that investigate complaints and can terminate agreements with violating businesses.
The Federal Trade Commission handles complaints about deceptive practices. If a merchant hides fees until after a transaction completes or misrepresents charges, the FTC may have jurisdiction.
State attorneys general have the strongest enforcement tools. They can issue cease-and-desist orders, impose civil penalties, and require businesses to refund affected consumers. Some states allow private lawsuits for consumer protection violations.
Your credit card issuer may also help. Disputing the surcharge portion of a charge sometimes succeeds, especially when merchants violated disclosure requirements.
Credit Card Surcharge Laws 2026
Credit card surcharge laws in 2026 reflect a stable regulatory environment with surcharges legal in 48 states and banned in Connecticut and Massachusetts. No major legislative changes occurred in the past year.
The 2026 landscape includes these current rules:
Federal level: No federal law directly regulates credit card surcharges. The Durbin Amendment (2010) addressed debit card interchange fees but left credit card surcharges to states and card networks.
State level: Connecticut and Massachusetts maintain complete bans. All other states allow surcharges with disclosure requirements. No state has passed new surcharge restrictions in recent legislative sessions.
Card network level: Visa and Mastercard continue enforcing the 3% cap and disclosure requirements. Both networks require merchants to register surcharging programs and apply fees consistently across card brands.
| 2026 Status | Details |
|---|---|
| States Allowing Surcharges | 48 |
| States Banning Surcharges | 2 (CT, MA) |
| Maximum Allowed | 3% or actual cost |
| Federal Regulation | None specific to surcharges |
| Enforcement Trend | Stable, focused on disclosure violations |
Recent trends show increasing surcharge adoption by small businesses facing inflation and rising operational costs. Consumer complaints have risen correspondingly, but enforcement remains consistent.
Looking ahead, no pending legislation appears likely to change the status quo. Both Connecticut and Massachusetts have resisted repealing their bans despite business pressure. States that allow surcharges show no appetite for new restrictions.
