Illinois interchange fee ban blocked, restaurants face ongoing tipping costs

Every card tip in an Illinois restaurant still runs through a payments system that can skim fees before a server ever sees the money. A federal judge’s injunction against the state’s Interchange Fee Prohibition Act keeps that plumbing intact for now, leaving operators to absorb the same processing costs tied to tips, sales taxes, payroll math, and bookkeeping.

The ruling blocked enforcement of a law that was designed to stop payment processors and financial institutions from charging interchange fees on the tip and tax portions of electronic transactions. In June, the U.S. District Court for the Northern District of Illinois found that federal law preempted the Illinois measure for national banks, federal savings associations, out-of-state state-chartered banks protected by federal law, and payment card networks. The American Bankers Association said the injunction also barred enforcement of the law’s data-usage limits against those covered institutions.

For restaurants, the fight has always been about more than banks. The National Restaurant Association backed the Illinois law through the Merchant Payments Coalition, saying swipe fees are among the highest and fastest-growing costs facing restaurant owners. The group also said the measure was the first state law of its kind to bar interchange fees on the sales-tax and tip portions of electronic transactions, a change that had been set to take effect statewide on July 1, 2026 before lawmakers pushed the date back.

Illinois lawmakers did that in early June, extending the implementation deadline to July 1, 2027. That delay came after an earlier round of litigation in which the law survived a challenge on Feb. 10, 2026, when the Northern District of Illinois upheld the core of the IFPA. At the time, the restaurant lobby said the ruling would put money back in the pockets of local restaurant owners, while opponents said they would appeal.

The divide has been sharp inside Illinois’ business community. The Illinois Bankers Association, Illinois Credit Union League, Illinois Chamber of Commerce, Illinois State Black Chamber of Commerce, and Illinois Hispanic Chamber of Commerce all warned that splitting out tips and taxes would be costly, complex, and disruptive, especially for small businesses. Trade groups on the other side argued the law could save businesses and consumers millions of dollars a year if it ever fully took effect.

The IFPA itself was folded into Illinois’ fiscal year 2024 budget after lawmakers and the governor capped an existing tax discount claimed by retailers to help close a budget gap. That origin matters because the dispute has never stayed in one lane: it has tied restaurant tipping, state budgeting, and payments policy into the same fight. For line cooks, servers, bartenders, and managers, the practical question is whether card-based tipping stays clean and fast, or whether legal delays keep turning earned gratuities into another source of accounting friction.
