Federal agency casts further uncertainty on Illinois’ credit card ‘swipe fee’ law

A federal agency says Illinois can’t limit credit card swipe fees for federally chartered banks, even though a federal judge earlier this year ruled that it could.

Two interim filings posted last week by the Office of the Comptroller of the Currency, an independent subsection of the U.S. Treasury Department, represent the latest twist in a two-year legislative fight between banks and retailers.

One of the filings specifically preempts the state’s first-of-its-kind Interchange Fee Prohibition Act, throwing the policy into further uncertainty by creating a second legal front and added pressure on state lawmakers amid an ongoing appellate court case.

Interchange or “swipe fees” are automatically applied to debit and credit card transactions, redirecting about 1-2% or more of a transaction’s cost from the merchant to the banks, credit unions and card companies. The fees include both a set amount and a percentage of the transaction, but the credit card companies, namely Visa and Mastercard, control how they’re calculated.

Illinois lawmakers passed the Interchange Fee Prohibition Act as part of the state budget in May 2024 to prohibit financial institutions from charging such fees on the tax and tip portion of credit and debit card transactions.

At stake is more than $100 million annually between retailers and banks, as exempting tax and tips from interchange fees would reduce the banks’ cut of swipe fees by 10% or more.

Banks have since warned of impending “credit card chaos.” They say the current system only asks for the total amount of a transaction, meaning consumers might have to do multiple swipes or pay cash to cover the tax and tip portion of transactions. Retailers say they’re bluffing and can implement the changes with mere software upgrades.

Given the pending court case and a hard push from financial institutions, lawmakers are considering pushing back the state law beyond its July 1 effective date that was already delayed by a year.

Reaction to the filings

The financial institutions praised the OCC’s filings but warned they create a piecemeal legal landscape by only applying to banks that are federally chartered. Smaller state-chartered institutions would still be subject to the law.

A joint statement from the Illinois Bankers Association, Illinois Credit Union League, American Bankers Association and America's Credit Unions urged similar application to national credit unions.

“They (the filings) reinforce the firm legal foundation of our ongoing appeal and underscore that Illinois’ misguided law is unlawful and should not be implemented,” the statement reads. “The OCC’s actions should also send a strong signal to other states to follow the law and not repeat Illinois' mistake.”

Rob Karr of the Illinois Retail Merchants Association accused the Trump administration of trying “to evade the law, undermine the legal system and threaten the very consumers they purport to serve.”

IRMA was heavily involved in the Illinois law’s passage, which was a concession to retailers after the state capped a tax exemption merchants claim for serving as the state’s de facto sale tax collectors.

“We are confident the courts will make the final decision in this matter — not an agency operating at the behest of big banks and credit card companies,” Karr said in a statement.

The case has been tied up in court for two years. The law initially was set to take effect in July 2025, but lawmakers pushed it back a year to allow time for implementation and to allow the court challenge to play out.

A U.S. district judge sided with the retailers and the state in February. Judge Virginia Kendall ruled that the National Banking Act prohibits states from regulating fees charged by banks — but swipe fees are set by third parties, namely card companies. Because of that, the state has the authority to regulate, she ruled.

But the banks quickly appealed to the 7th Circuit Court of Appeals, and arguments are slated for May 13. Some believe the matter could even come before the U.S. Supreme Court.
