Iowa Credit Card Surcharge Law
Iowa credit card surcharge law allows surcharging. No state statute bans or caps it, so card network rules set the ceiling. The section people cite as Iowa's surcharge law is a lending statute that says nothing about your counter.
Iowa Allows Credit Card Surcharging
No ban, no cap, no disclosure statute. The state layer is empty.
As of July 2026, Iowa has never passed a law banning, capping, or regulating credit card surcharges for private businesses. There is no state disclosure statute either. With no state statute in play, the card networks set the rules, the same as they do everywhere else surcharging is legal.

Iowa is one of 47 states where surcharging is legal. See the full table at credit card surcharge laws by state.
The Card Networks Set the Ceiling
With no state cap on the books, Visa and Mastercard's own rules do the work.
-
Visa: 3% Cap
In force nationwide since April 2023. Iowa has no state ceiling.
-
Mastercard: 4% Cap
Same network standard as Visa applies, just a higher ceiling.
-
Debit Never Surcharges
Debit, prepaid, and gift cards can never carry a surcharge, in Iowa 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.
Two Numbers, No State Layer
With no state statute on the books, Visa's 3 percent and Mastercard's 4 percent are the only numbers an Iowa dealership runs against. A standard 3 percent credit card surcharge sits inside Visa's cap.
What Iowa Law Actually Says
The section people point to is not a surcharge law at all.
Guides around the web cite Iowa Code 537.2501 as if it were Iowa's surcharge law. It is not. That section sits in the Iowa Consumer Credit Code and lists the additional charges a creditor may add in a consumer credit transaction, things like official fees, insurance charges, and annual credit card membership fees. The only surcharge anywhere in the entire section is for a bounced check, tucked into subsection 1(g). It says nothing about what a merchant may add at the point of sale. Iowa has no merchant surcharge statute at all; the card network rules are the whole rulebook.
Iowa Code 12.21 lets state departments add a fee for taking credit card payments on what residents owe the state. That authority covers government payments, not private businesses, and has no bearing on what a dealership charges a customer.
House Study Bill 324, introduced in the Iowa House in April 2025, would have barred interchange fees on the tax portion of card transactions. A Ways and Means subcommittee recommended passage twice, in April 2025 and again in March 2026, but the bill never got a full committee vote and died when the legislature adjourned on May 3, 2026. As of July 2026 it is not law. And it was never a surcharge bill: it targeted the interchange fees networks charge merchants upstream, not what a dealership may surcharge a customer. Iowa's surcharge rules were never in play.
The Playbook Does Not Change
House Study Bill 324 never touched the surcharge playbook. The program already posts notice at the point of entry and the point of sale and itemizes the surcharge on the receipt. We track the state, not your front desk.
What This Means at the Counter
One playbook, plus one tax wrinkle for your accountant.
The checklist at an Iowa counter is the card network playbook and nothing more. A standard 3 percent credit card surcharge sits inside Visa's cap, with notice posted at the point of entry, posted again at the point of sale, and the surcharge itemized as its own line on the receipt. Debit never carries a surcharge, no exceptions and no workarounds.
The one wrinkle: the Iowa Department of Revenue's Sales and Use Tax Guide treats a credit card processing fee charged on a taxable sale as part of the taxable sales price. Tax applies to the fee on taxable work; on a nontaxable sale, the fee is not taxable. Ask your accountant how that lands on your ROs. It is a tax question, not something this program calculates, files, or advises on.
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 exactly what happens at the terminal on the how it works page.
