Mastercard Surcharge Rules
Mastercard surcharge rules let a franchise dealership add a fee to a Mastercard credit card transaction, up to 4 percent, but never more than the store's own cost of accepting that card. Debit and prepaid Mastercard cards are always off limits, no matter which button gets pressed at the terminal. This page breaks down what Mastercard actually requires: the real cap, the two ways to structure it, the disclosure rules, and where a state law can tighten things further.
The 4% Cap, Capped at Your Cost
4 percent is the ceiling, not the number every dealership gets to charge.
-
Visa: 3% Cap
In force since April 2023, for contrast only. Mastercard did not follow.
-
Mastercard: 4% Cap
Capped at your actual cost of acceptance, with 4 percent as the ceiling.
-
Debit Never Surcharges
Debit and prepaid Mastercard cards can never carry a surcharge.
-
Disclosure Is Mandatory
Notice at entry, notice at checkout, and its own line on the receipt.
The real rule is not a flat 4 percent allowance. Mastercard caps your surcharge at your own cost of accepting that Mastercard credit card, full stop, and 4 percent is simply the ceiling that cost can never cross. If your cost of acceptance sits below 4 percent, your surcharge cap sits at that lower number too, not at 4 percent.
As of July 2026, Visa's cap sits at 3 percent and Mastercard's cap sits at 4 percent. Visa cut its cap to 3 percent effective April 2023. Mastercard did not follow, and its rule ceiling has stayed at 4 percent since. A dealership running one uniform rate across both brands still answers to Visa's lower number, but Mastercard's own rule allows more room.
Worked Example
Take a store with a 2.5 percent cost of acceptance on Mastercard credit cards. Its surcharge cap is 2.5 percent, not 4 percent, because the rule caps at cost first and 4 percent only sets the outer limit.
Brand-Level or Product-Level, Not Both
Mastercard allows two different surcharging methods. A dealership picks one and runs it consistently.
Brand-level surcharging applies one rate to every Mastercard credit card that comes through the terminal, no matter which bank issued it. Product-level surcharging goes a level deeper: it sets a separate rate for each Mastercard product tier, Standard, World, and World Elite for example, each priced on its own.
| Method | How It Works |
|---|---|
| Brand-level surcharge | One surcharge rate applies to every Mastercard credit card, regardless of the issuing bank. |
| Product-level surcharge | A separate rate applies to each Mastercard product tier, each set on its own. |
A dealership chooses one method, not both at once, and applies it the same way across every Mastercard credit transaction. Switching methods transaction by transaction is not how the rule works.
Debit and Prepaid Stay Off Limits
No surcharge, no lower rate, no exception, and the mechanism is not the one most guides name.
Debit and prepaid Mastercard cards can never carry a surcharge. This holds true even if the card gets run through the terminal's credit button. Pressing credit does not turn a debit card into a credit card. The card's underlying type is what the rule tracks, not which button gets pressed at checkout, so a debit card run as credit still cannot be surcharged.
The source of this rule matters, because it gets misattributed often. The debit no-surcharge rule comes from Mastercard's own network rules, put in place through its 2013 merchant settlement, not from the Durbin Amendment. Durbin caps what banks can charge merchants in debit interchange fees. It has nothing to do with whether a merchant may surcharge a debit card. The ban on debit surcharges is a Mastercard network rule, on its own.
Notice, Then Disclosure
One notice before you start, then three disclosure points every time a Mastercard credit card is surcharged.
Before a dealership can start surcharging Mastercard credit cards, Mastercard's rules require at least 30 days' advance notice to your acquirer. Your acquirer registers you with the card networks off the back of that notice, and it happens as part of onboarding, well ahead of the first surcharged transaction.
| Where | What Mastercard Requires |
|---|---|
| Store entry or first e-commerce page | Post your surcharge policy and note that it is never higher than your Mastercard cost of acceptance. |
| Checkout or point of sale | Show the surcharge percentage, that the dealership, not the card network, is imposing it, and that it is not higher than your cost of acceptance. |
| Receipt | Show the surcharge as its own line, separate from the sale price. |
A dealership writes its own signage for these disclosures, and one sign at the door can cover both Visa and Mastercard together. None of this is a workaround; it is the standard Mastercard expects every merchant to meet, every time a credit surcharge applies.
What the Guides Get Wrong
Three claims that circulate constantly, and what Mastercard's own rules actually say.
"Visa and Mastercard both dropped to 3 percent in 2023"
Only Visa moved. That cap cut was a Visa decision, not a joint one, and Mastercard's ceiling never followed it down. The two networks have run different numbers ever since.
"There is a federal 4 percent surcharge cap"
There is no federal law setting a 4 percent, or any, surcharge cap. The 4 percent figure is a Mastercard network rule, not a statute. A state can set its own tighter limit, or ban surcharging outright, and Mastercard's rule yields to that state law.
"The Durbin Amendment bans debit card surcharges"
The debit no-surcharge rule is a Mastercard network rule, not the Durbin Amendment. Durbin caps debit interchange fees charged to merchants; it does not touch whether a merchant can surcharge a debit transaction. Mastercard's own rule is what makes that a flat no.
What This Means at Your Store
None of the rules above are something your front desk has to track on its own.
The 30-day notice to your acquirer, the disclosure signage, and the setup that keeps every transaction inside Mastercard's rules are handled as part of onboarding under the surcharge program. Your team makes zero compliance decisions at the counter.
At the terminal, card type is read automatically. A Mastercard debit or prepaid card passes through with no fee, every time, without an advisor having to check anything. A Mastercard credit card shows the disclosed surcharge, the customer accepts it with one tap, and the payment posts straight to the repair order. Walk through the full sequence on the how it works page.
State law can tighten what Mastercard allows, never loosen it. A dealership watching for a change in its own state, or operating across more than one, can check the current status on the surcharge laws by state hub. For what running the program costs, see pricing.
Straight Answers on Mastercard's Rules
4 percent is the outer limit only. Your real number is whatever your dealership actually pays to accept that card, which is usually lower.
No, only Visa moved. If you run one blended rate across both brands, Visa's tighter 3 percent number is the one that actually governs you, even though Mastercard's own rule leaves more room.
Never. Debit and prepaid Mastercard cards cannot carry a surcharge, even if the card gets run through the terminal's credit button. This is a Mastercard network rule, not the Durbin Amendment.
Yes. Mastercard's rules require at least 30 days' advance notice to your acquirer before you start. Your acquirer then registers you with the card networks.
Yes, but only in one direction. A state can cap the surcharge below 4 percent or ban it outright, and Mastercard's rule yields to that law. A state can never loosen what Mastercard allows. See the surcharge laws by state hub for your state's status.
