Illinois Credit Card Chaos: Understanding the Interchange Fee Prohibition Act

Illinois is currently the center of a fierce battle between financial institutions and retailers over a first-of-its-kind law that could fundamentally change how consumers pay for services. The Interchange Fee Prohibition Act (IFPA), slated to take effect on July 1, 2026, has sparked a million-dollar ad campaign warning of “credit card chaos” at checkout lines across the state.

What is the Interchange Fee Prohibition Act?

At the heart of the controversy are “swipe fees,” formally known as interchange fees. These are fees—typically ranging from 1% to 3%—that credit card companies charge merchants on every transaction to help fund rewards programs and fraud prevention.

The IFPA prohibits financial institutions from charging these interchange fees on the specific portions of a consumer’s bill attributed to sales tax and tips. The law bans these institutions from recouping those lost fees by increasing charges elsewhere in the transaction. The law was championed by the Illinois Retail Merchants Association, which views the measure as a victory for consumers and businesses.

The Battle: “Scare Tactics” vs. “Technical Impossibility”

The conflict has split into two starkly different narratives regarding the law’s feasibility and impact.

The Financial Institutions’ Warning

The Electronic Payments Coalition (EPC)—a lobbying group representing community banks, credit unions, card networks and issuing banks—argues that the law is unworkable. Richard Hunt, Executive Chairman of the EPC, has described the situation as a “reckless policy” that could turn Illinois into the “land of chaos.”

The EPC’s primary concerns include:

• Technical Limitations: Financial institutions claim the global payment system cannot currently distinguish between tax, tips, and the total amount of a transaction.
• Payment Disruptions: The coalition warns that credit and debit cards may stop working for the tip or sales tax portions of a bill, forcing consumers to pay those amounts in cash.
• Collateral Damage: The EPC suggests that tipped workers could lose income if customers are unable to tip via card, and small businesses could suffer from lost sales and frustrated customers.

The Retailers’ Perspective

Retailers and proponents of the law dismiss these warnings as misinformation. Rob Karr, president and CEO of the Illinois Retail Merchants Association, has characterized the EPC’s ad campaign as a “scare tactic” designed to protect the profits of major financial institutions rather than the interests of consumers.

Legal Status and Next Steps

The path to July 1 has not been smooth. The IFPA has already faced legal hurdles, though it recently survived its first legal challenge. Despite this victory for the law’s supporters, the legislation remains under appeal as the EPC continues to urge Illinois lawmakers to repeal the act.

Frequently Asked Questions

Will my credit card stop working in Illinois?

According to ads from the Electronic Payments Coalition, there is a risk that cards may not perform specifically for tips or sales tax starting July 1. However, retailers argue these claims are misinformation.

What are interchange fees?

Interchange fees, or “swipe fees,” are the 1% to 3% charges that card networks and banks levy on merchants for processing electronic payments.

Is this law active in other states?

No. The IFPA is described as a first-in-the-nation law, with the EPC noting that no other jurisdiction has attempted a similar ban on fees for tax and tip portions of transactions.

As the July 1 deadline approaches, the resolution of the ongoing legal appeals will determine whether Illinois consumers and merchants face a seamless transition or the “credit card chaos” predicted by financial institutions.
