IntelliPay is a PCI DSS Level 1 certified payment processor and AutoManager’s integrated payment partner for dealerships. This guide covers the card network rules and state laws that decide whether, and how, your dealership can surcharge. Learn more about payment solutions for auto dealers and repair shops.
Quick Answer
Yes, most dealerships can legally add a surcharge to credit card payments, as long as they follow card network rules and state law.
Five rules cover most of it:
- Never surcharge more than your cost to accept the card or 3%, whichever is lower.
- Never surcharge debit or prepaid cards, even when they’re run as credit.
- Notify your processor at least 30 days before you start.
- Use one rate and the same terms for Visa, Mastercard, Discover, and American Express credit cards.
- Disclose the surcharge at the entrance, at checkout, and on the receipt.
Surcharging is banned in Connecticut, Maine, Massachusetts, and Puerto Rico. The pending Visa and Mastercard settlement is not in force yet, so today’s rules still apply.
Why Dealers Look at Surcharging
Visa, Mastercard, and the other card networks set interchange and assessment fees on every card transaction. You can’t negotiate those. What you can negotiate is your processor’s markup on top of them. The card type and how it’s taken both affect the cost. Premium rewards cards keyed in or used online cost the most, and issuers use that money to fund cardholder rewards. In plain terms, your margin is helping pay for someone else’s vacation or cash back.
Visa and Mastercard typically update interchange in April and October. The biggest national retailers negotiate their own rates. Dealers and smaller businesses usually don’t have that leverage, so each increase comes straight out of margin. Surcharging lets you recover that cost from customers who choose to pay with a credit card.
Surcharging isn’t illegal, unethical, or unusual. You’ll see it at towing companies, repair shops, and other auto-related businesses. For dealers it has one more advantage: you can accept a card for a larger down payment or a big service ticket without eating 3% of it.
It’s more than adding a line to a receipt, though. Card network rules, state law, and disclosure requirements all apply, and the penalties for getting it wrong land on you and your processor.
What Is a Surcharge Fee?
A surcharge is an amount added to the total when a customer pays with a credit card. It can be used for in-person, online, and phone payments. The surcharge can’t exceed your cost of acceptance for that card or 3%, whichever is lower. If your cost to accept a card is 2.4%, your maximum surcharge on that card is 2.4%, not 3%.
Surcharges are never allowed on debit cards, prepaid cards, or gift cards. That includes a debit card the customer runs as “credit.” Your POS system or payment platform should apply the surcharge automatically, and it needs to tell a credit card from a debit card in real time to do it correctly.
Surcharges, cash discounts, and convenience fees
These three get mixed up all the time, and the rules for each are different.
| Fee type | How it works | Key limits |
|---|---|---|
| Surcharge | A percentage added only when the customer pays with a credit card. It’s triggered by the payment method. | Credit cards only. Lower of cost or 3%. 30-day notice. Banned in some states. |
| Cash discount or dual pricing | You post a card price and a lower cash price, and give the discount to customers who pay by cash or check. | If you post one price and add a fee at checkout for card payments, the networks treat it as a surcharge, no matter what you call it. |
| Convenience fee | A flat dollar amount for paying through an alternative channel, such as online or by phone, when your standard way to pay is somewhere else. | Must be flat, not a percentage, and clearly disclosed. Not allowed on in-person payments. Can apply to credit, debit, and prepaid cards. |

Card Network Rules for Surcharging
Visa, Mastercard, Discover, and American Express all allow surcharging, with conditions.
| Card network | What the rules say |
|---|---|
| Visa | Cap is the lower of your cost of acceptance or 3%. Visa lowered the cap from 4% to 3% on April 15, 2023. Notify your acquirer (processor) at least 30 days before you start. Disclose the surcharge at the store entrance, at the point of sale, online before checkout, and as a line item on the receipt. Credit cards only. You can surcharge at the brand level (all Visa credit cards) or the product level (specific card products), not both. See Visa’s surcharging requirements. |
| Mastercard | Cap is the lower of your average effective merchant discount rate for Mastercard credit or 4%. Give Mastercard and your acquirer at least 30 days’ notice. Disclose at the point of interaction and show the dollar amount on the receipt. No surcharges on Debit Mastercard or prepaid cards. See Mastercard’s surcharge rules. Since most dealers apply one rate to every brand, Visa’s 3% cap is the practical limit. |
| Discover | Cap is your cost of acceptance for the Discover card sale. Discover doesn’t publish a percentage cap, but if you use one rate across brands, Visa’s 3% limit still applies. Give at least 30 days’ written notice before you start, through your processor. You can’t treat Discover cardholders worse than customers using the same type of card on another network, so if you surcharge Discover credit cards, surcharge other credit cards the same way. Disclosure: at the point of entry (and online, on the page that shows the card brands you accept), state that the surcharge is not greater than your cost of acceptance. At the point of sale, show the amount or percentage and that you, the merchant, are adding it. On the receipt, show the dollar amount as its own line between the subtotal and the total. |
| American Express | Amex’s U.S. rules say merchants can’t impose fees or conditions on Amex cards that aren’t imposed equally on other card products. Cash, check, and electronic funds transfers are exceptions (American Express Merchant Reference Guide). In practice, you can surcharge Amex cards only at the same rate and on the same terms as your other credit cards, and never higher. Amex doesn’t publish its own percentage cap or advance notice rule, but your rate still can’t go above your cost, Visa’s 3% cap, or your state’s limit. Disclose the fee clearly before the customer pays, just as you do for the other brands. |
Why the American Express and Discover rules matter
Both networks require you to treat their cardholders the same as customers using other credit cards. Under today’s Visa and Mastercard rules, a merchant that accepts Amex generally has to surcharge Amex on the same terms in order to surcharge Visa and Mastercard. The simple approach for most dealers is one surcharge rate for all credit cards, set at or below your cost of acceptance and the 3% cap, with no surcharge on any debit or prepaid card.
The networks can see who is surcharging
- Gateways and POS systems now send the surcharge amount in a dedicated field in the transaction data. Notifying your processor isn’t just a best practice. It’s required.
- Visa runs mystery-shopping audits looking for surcharges above the cap or on debit cards. Fines start with the acquirer and get passed down to the merchant.
State Surcharge Laws Dealers Need to Know
Card network rules are only half of it. State law applies on top, and it has changed a lot since 2023.
| State | What the law says |
|---|---|
| Connecticut, Maine, Massachusetts, Puerto Rico | Surcharging is banned (CT Department of Consumer Protection; 9-A M.R.S. § 8-509, which covers credit and debit in Maine). Cash discount programs are still allowed when set up correctly. |
| Colorado | Up to 2% of the total, or up to your actual merchant discount fee. Post the exact notice wording the statute requires, show the surcharge as a separate receipt line, and apply only one surcharge per transaction (C.R.S. § 5-2-212). |
| New Jersey | No more than your actual cost to process the credit card payment. Disclose the amount at the point of entry and the point of sale, on your online checkout page, and verbally on phone payments (NJ Attorney General FAQ). |
| New York | Since February 11, 2024, you have to post the total credit card price in dollars and cents, not just a percentage. On a sticker price or a service quote, that means showing what the customer will actually pay by card (NY Department of State). |
| Oklahoma | SB 677 repealed the old ban. As of November 1, 2025, surcharges are allowed up to the lower of 2% or your actual cost, with disclosure required (Oklahoma Legislature). |
| California | SB 478 has required all-in pricing since July 1, 2024. If the customer can avoid the fee by paying another way, a surcharge may be allowed. If a card is the only way to pay, the fee has to be built into the advertised price. |
| Texas | A ban is still on the books, but a federal court blocked enforcement against the merchants who challenged it. Talk to counsel before you surcharge in Texas. |

What Could Change: The Visa and Mastercard Settlement
On June 9, 2026, a federal judge granted preliminary approval to the revised Visa and Mastercard swipe fee settlement (America’s Credit Unions). If it gets final approval, it would:
- Let merchants surcharge Visa and Mastercard credit cards up to the lower of 3% or their cost of acceptance, whether or not they surcharge American Express.
- Let merchants decline whole card categories, such as premium or commercial credit cards, with 30 days’ notice to their acquirer.
- Lower average credit interchange by 10 basis points for five years (Forbes).
None of this is in force yet. Final approval is expected in late 2026 or early 2027, and some merchant groups have said they will appeal. State law isn’t affected either way. Don’t change your surcharge setup until your processor confirms the new rules have taken effect.
How Dealers Can Use Surcharging
- Accept cards on bigger tickets. With the processing cost covered, you can take a card for a larger down payment, deposit, or repair order instead of setting a low card limit or pushing customers to a check.
- Set rates by department. If sales and fixed ops run on separate merchant accounts with different costs, each can carry its own surcharge rate. Neither can go above that account’s cost of acceptance or the 3% cap.
- Improve cash flow. Lower net processing costs go straight to the bottom line.
Illustrative example
A dealership running $200,000 a month in card payments at a 2.9% effective rate pays about $5,800 a month, or $69,600 a year, in processing fees. A compliant surcharge on credit card sales can recover most of the credit share of that cost. Debit card sales still carry their normal cost, which is why splitting credit and debit volume correctly matters.
Is Surcharging Right for Your Dealership?
1. Know your effective rate
Divide one month’s total processing fees by that month’s total card sales. If you paid $450 in fees on $15,000 in card sales, your effective rate is 3.0%. That number tells you what you can legally recover. IntelliPay can do this for you. Send us a few recent processing statements and answer a few questions, and we’ll show you your effective rate and a compliant surcharge amount.
2. Check your state
If you’re in a state that bans surcharging, look at a cash discount or dual pricing program instead.
3. Look at your competition
If other dealers in your market already surcharge, your customers are used to it. If they don’t, a clear sign and a no-fee debit or ACH option go a long way.
4. Go-live checklist
Before your first surcharged transaction, make sure you have:
- ☐ Notified your processor at least 30 days in advance, along with Mastercard and Discover as their rules require.
- ☐ Set one surcharge rate and the same terms for Visa, Mastercard, Discover, and American Express credit cards.
- ☐ Posted signage at the entrance and at every place you take payment.
- ☐ Added disclosure to your online payment page before the customer submits.
- ☐ Set up the surcharge as a separate line item on every receipt.
- ☐ Turned on automatic credit and debit card detection, so debit and prepaid cards are never surcharged.
- ☐ Confirmed your rate is at or below your actual cost and any state cap.
The bottom line
Surcharging can protect your margins, but it isn’t a do-it-yourself project. Card network rules and state laws keep changing, and the settlement could change them again.

Request a Free AnalysisFrequently Asked Questions
Can car dealers legally add a credit card surcharge in 2026?
Yes, in most states. Surcharging is banned in Connecticut, Maine, Massachusetts, and Puerto Rico. Colorado, New Jersey, New York, Oklahoma, and California have their own caps or pricing rules, so check your state first.
What’s the maximum surcharge a dealership can charge?
The lower of your actual cost to accept the card or 3%. Mastercard’s rules allow up to 4%, but Visa caps surcharges at 3%, and most dealers use one rate for every brand. Some states set a lower cap, such as 2% in Colorado and Oklahoma.
Can I surcharge debit cards at my dealership?
No. Card network rules prohibit surcharges on debit and prepaid cards, even when the customer runs a debit card as credit.
Do I have to notify anyone before I start surcharging?
Yes. Visa requires at least 30 days’ notice to your processor. Mastercard requires 30 days’ notice to both Mastercard and your processor. Discover requires 30 days’ written notice. You also need to post signage and disclose the surcharge before the customer pays.
Can I surcharge American Express and Discover cards?
Yes, as long as you treat them the same as other credit cards. American Express doesn’t allow fees on Amex cards that aren’t applied equally to other card products. Discover caps the surcharge at your cost of acceptance and requires 30 days’ written notice. Use one rate for all credit card brands and never go above your actual cost.
Is a convenience fee the same as a surcharge?
No. A convenience fee is a flat amount for paying through an alternative channel, like online, and can’t be charged in person. A surcharge is a percentage added only to credit card payments.
Can I charge a different surcharge in sales and service?
Yes, if sales and fixed ops run on separate merchant accounts with different costs. Each rate has to stay at or below that account’s cost of acceptance, the 3% cap, and any state limit.
Does the Visa and Mastercard settlement change surcharging rules now?
Not yet. The settlement received preliminary approval on June 9, 2026, but its changes don’t take effect until final approval. Until then, current network rules and state laws apply.
