Wisconsin Credit Card Surcharge Law
Wisconsin credit card surcharge law allows surcharging, with no state statute on the books that bans it, caps it, or sets disclosure rules for a private merchant like a dealership. Card network caps set the ceiling instead. The one wrinkle worth knowing is a tax one: Wisconsin treats the surcharge as part of the taxable sale.
Wisconsin Allows Credit Card Surcharging
No statute bans it, caps it, or sets disclosure rules for it. Not one on the books for a private merchant like a dealership.
Wisconsin has no state statute in force that bans, caps, or imposes disclosure requirements on credit card surcharges by private merchants. A dealership charging a standard credit card surcharge is not working around any Wisconsin law. The card network rules are the whole rulebook here, and there is no Wisconsin section number to cite against a private business.
Lawmakers tried once: in 2013, Senate Bill 213 would have written a surcharge ban into Wisconsin's cash discount law, but it never reached a floor vote and died when the session closed in 2014, and nothing has replaced it since.

As of July 2026, Wisconsin is one of 47 states where surcharging is legal, every state except Connecticut, Maine, and Massachusetts. See the full table at credit card surcharge laws by state.
The Card Networks Set the Ceiling
With no state statute on the books, Visa and Mastercard's own rules do the work.
-
Visa: 3% Cap
Visa caps credit card surcharges at 3 percent nationwide. Wisconsin has no lower state ceiling.
-
Mastercard: 4% Cap
Mastercard caps credit card surcharges at 4 percent nationwide, its own standard alongside Visa's.
-
Debit Never Surcharges
Debit, prepaid, and gift cards can never carry a surcharge, in Wisconsin or anywhere else.
-
Disclosure Is Mandatory
Post notice at the door and the counter, and show the surcharge as its own line on the receipt.
No State Cap Does Not Mean No Ceiling
A missing state statute is not an open field. Visa's 3 percent and Mastercard's 4 percent still apply to every Wisconsin dealership, and they are the only numbers a dealership needs to run against today. A standard 3 percent credit card surcharge sits inside Visa's cap.
The One Law on the Books Is on Your Side
Wisconsin has a single statute that speaks to card pricing, and it protects the merchant.
Search the Wisconsin statutes for a surcharge rule and you will not find one. No section limits what a dealership may add for a credit card payment. The one Wisconsin law that touches card pricing at all runs the other way and protects the merchant: Wisconsin Statute 422.422, the state's cash discount law, says a credit card company cannot use its contract to stop a business from offering customers a discount for paying by cash or check.
That statute matters here for one reason. It is the exact provision the 2013 bill tried to change. Senate Bill 213 would have bolted a surcharge ban onto the cash discount law, and it failed, so the section reads today as it has since 2005: it shields cash discounts and says nothing to restrict a surcharge. For a dealership the takeaway is simple. Wisconsin leaves the surcharge rules to the card networks, and the only state law in this corner is one that keeps your pricing options open.
No Wisconsin Surcharge Statute
There is nothing to comply with at the state level, because Wisconsin never passed a surcharge law. A disclosed program that stays inside the network caps is already doing everything state law asks, which is nothing, and everything the networks ask, which is disclosure.
What This Means at the Counter
The counter needs three things right, plus one note for your accountant.
Customers pay the standard credit card surcharge, and disclosure is handled at the door, at the point of sale, and as a line on the receipt. Debit never carries a surcharge, in Wisconsin or anywhere else, with no exceptions and no workarounds. Phone, text to pay, and online link payments run through the program with the same required disclosure, and when a payment is refunded the surcharge refunds automatically and proportionally. We track the state, not your front desk.
One Wisconsin specific note for your accountant. The Wisconsin Department of Revenue treats a credit card surcharge as part of the taxable sales price. In guidance published in January 2024 and restated in April 2025, the department said that when a taxable item is sold, the added credit card fee is taxable too, so state sales tax applies to the surcharge along with the item. Wisconsin's state sales tax is 5 percent and most counties add a local share on top. How you handle that on your system is a question for your tax advisor. DealerPayments does not calculate, file, or advise on sales tax.
Payments post straight to the repair order in CDK Drive, so the surcharge line shows up where your advisors already work. See the full mechanics on the surcharge program page, or walk through what happens at the terminal on the how it works page.
Straight Answers on Wisconsin Rules
Yes. Wisconsin has no state statute that bans or caps credit card surcharges for private merchants. Card network rules govern instead.
No. There is no Wisconsin state cap. Visa's 3 percent ceiling governs a credit card surcharge, and Mastercard allows up to 4 percent under its own rules.
Wisconsin has no state disclosure statute for private merchants. The standard comes from the card networks: post notice at the point of entry, post it again at the point of sale, and show the surcharge as its own line on the receipt. For pricing and program questions beyond state law, see the FAQ page.
No. Debit, prepaid, and gift cards can never carry a surcharge, in Wisconsin or any other state. That is a card network rule, not a state one, and it follows the card itself regardless of how it runs at the terminal.
Yes. The Wisconsin Department of Revenue has said a credit card surcharge is part of the taxable sales price, so when the item being sold is taxable, state sales tax applies to the surcharge too. The state rate is 5 percent plus any county share. Talk to your accountant about how to handle it. DealerPayments does not advise on tax.
