Is credit card surcharging legal in Wisconsin?

Yes, as far as state law goes. We found no Wisconsin statute that specifically addresses credit card surcharging. We found no Wisconsin statute banning or capping merchant credit card surcharges. The provision the NFIB Legal Center cites, Wis. Stat. § 422.422, runs the other way: it stops card issuers from restricting a merchant's ability to offer cash discounts. We have not independently verified that section, so treat this entry as provisional and rely on card-network rules for the operative limits.

Under review

We could not confirm this entry against a Wisconsin statute or a state agency publication. Everything below is written as our current reading of secondary sources, not as a settled statement of Wisconsin law. Verify with counsel before you rely on it.

The statute

Citation: Wis. Stat. § 422.422 (cash discounts) — not independently verified

We have not reproduced operative text here because we could not confirm a clean verbatim quote against the official source. Follow the citation and the source links below.

How much you can charge

We found no Wisconsin cap. No state cap. The binding limits are the card networks: Visa caps a credit card surcharge at the lower of your merchant discount rate or 3% (reduced from 4% effective 15 April 2023) and Mastercard caps it at 4%. Surcharging debit cards is prohibited nationwide.

Disclosure requirements

No state-specific disclosure statute located. Card-network rules still require the surcharge to be disclosed before checkout, itemised as its own line on the receipt, and notified to your acquirer at least 30 days in advance.

Not legal advice

This page is a research summary for merchants, not legal advice, and no attorney-client relationship is created by reading it. Surcharge rules change, they interact with card-network rules and federal law, and they can turn on facts specific to your business. Consult licensed counsel in Wisconsin before you implement or change a surcharge.
