Louisiana recently passed a new law that restricts businesses from charging customers extra for paying with a debit card. Act 751 takes effect on August 1, 2026, officially banning surcharge fees on debit cards throughout the state of Louisiana.
But it raises the obvious question: Wasn’t this already illegal?
The answer is yes, it was (and still is). But not exactly in the way that this is often explained. And it points to a larger trend worth talking about further around federal enforcement and state-level laws.
Were Debit Card Surcharges Already Illegal?
You’ll frequently hear that debit card surcharges are illegal nationwide under federal law.
We’ve used versions of that shorthand before, too. Because it gets merchants to the correct practical answer that they should not add a surcharge to debit card transactions.
But technically, the federal law explanation isn’t quite right.
The Durbin Amendment gives the Federal Reserve authority over debit card interchange, routing, and related network rules. However, it doesn’t explicitly state a provision that bans businesses from adding a surcharge fee when someone pays with a debit card.
Though it does pave the way for networks, issuers, and acquirers to regulate fees. And that’s largely where the practical debit surcharge prohibition language comes from: It’s network operating rules layered on top of the federal debit framework.
Card Network Rules Are Not the Same as State or Federal Enforcement
The problem with this gap is that there are no civil or criminal penalties at the federal level when a business “illegally” adds a surcharge fee on a debit card transaction.
Those fines would have to come from the network, acquirer, or both.
For example, Visa fines acquirers $1,000 for violations (that penalty will certainly be passed to the merchant). Mastercard, Discover, and Amex have similar rules, which are all completely enforceable based on your merchant agreement.
But that’s very different from the feds knocking on your door with a “legal” penalty. And even with the network rules in place, enforcement is sporadic at best.
Let’s say that a customer notices an extra 3% fee on a debit card transaction. The average consumer may not know:
- That the surcharge is prohibited by the network
- Which card network’s rules apply
- Whether to contact the merchant, bank, processor, or network
- How to submit evidence of the violation
- Whether anything will happen after the complaint
Furthermore, card network rules don’t necessarily give that customer a direct claim against the business under state law.
So even if that customer does know all of the above, are they really going to take all those steps over an extra $0.75 they were charged? It’s not like they’re going to see a piece of any fines paid by the business.
State-Level Debit Card Surcharge Bans Fill Those Gaps
Act 751 is a short law. But addresses nearly everything that the federal language and network-specific rules miss.
Louisiana’s new law gives customers and the state three things that didn’t exist before:
- Direct Claim Against the Business: Cardholders can recover actual damages, with a private right of action for willful violations, repeated violations, or violations the business fails to fix.
- Attorney General Enforcement: Louisiana’s AG can bring civil action and recover attorney fees, court costs, and investigative costs, plus civil penalties up to $500 per violation.
- A Place to Report Violations: The AG is required to maintain a toll-free number and electronic reporting system built specifically for surcharge complaints.
It’s also worth noting that while this is definitely a consumer protection law, it’s not written in a way that’s unfair to merchants. The law contains a “cure period” that gives the business 30 days to correct the problem and reimburse the surcharge after receiving written notice from the customer.
So if there’s a genuine mistake, merchants have a chance to make it right instead of just automatically getting hit with fines and lawsuits.
Other States Are Doing Versions of the Same Thing
New Jersey’s S4107 passed the Senate 40-0 on June 18, 2026 and is currently sitting on the Assembly Commerce and Economic Development Committee. It covers surcharges on debit cards, surcharges on gift cards, and treats violations as unlawful practices under the state’s Consumer Fraud Act, which is already a well-established enforcement path in the state.
Colorado landed in a similar place while coming from the opposite direction. When SB 21-091 legalized credit card surcharges up to 2% back in 2021, the same law explicitly prohibited surcharge fees on cash, checks, debit cards, or gift cards.
Other states ban surcharging outright (which apply to debit cards). And even in some states where surcharging is illegal, there are state laws in place to prohibit extra fees charged on debit card transactions.
Surcharging Debit Cards Doesn’t Make Financial Sense for Businesses
The idea behind surcharging is that you’re recouping costs for swipe fees. But regulated debit card transactions are capped at 0.05% + $0.21 (plus $0.01 for fraud prevention) at the interchange level.
On a $60 regulated debit transaction, the interchange cost would be about $0.25. While a 3% surcharge on that transaction would be $1.80.
I understand that the interchange component doesn’t represent the merchant’s entire cost of accepting that card. You still have to account for processor markups, authorization charges, assessments, and other costs layered on top.
But surcharges aren’t meant to be a profit center. And there’s no reason to pass costs to your customers that well exceed your cost of acceptance.
Once you factor in the potential penalties from the card networks and your acquirer, you could be paying thousands of dollars over something that would have just cost a few cents.
Surcharge Programs Aren’t Built to Detect Debit Cards
One of the biggest problems with surcharge programs is that operationally, it’s near impossible to distinguish from a credit or debit card at the point of sale.
Roughly 70% of POS systems are contactless. And about 90% of new POS terminals support contactless payments.
So an employee is never touching the card or mobile wallet.
With a surcharge program enabled, the POS automatically adds the fee to every card transaction. It’s not like the fee disappears when a debit card gets tapped.
The customer would have to notify the employee or the employee would have to ask. And that’s just not how transactions are happening practically anywhere.
So if you do have a surcharge program, you’re 100% exposed to card network and processor penalties. And if you’re in a state that officially bans debit card surcharges or plans to ban them soon, you can face even more legal penalties (in the actual “legal” sense).
Final Thoughts
I think the state-level bans on debit card surcharging are overall a good thing. They’re filling gaps where enforcement either lacked or was non-existent at all.
For merchants, debit card transaction fees are among the lowest of all merchant fees. So you probably shouldn’t be charging your customers extra for these anyway.
The debit card surcharge fee bans are passing much quicker and smoother than broader outright bans on all surcharges. So I think we’ll see this trend continuing in other states, particularly those that attempted to pass other surcharge-related restrictions that failed along the way.
