The Fight Over Swipe Fees: Understanding the Illinois Interchange Fee Prohibition Act
Small businesses have long complained about the “hidden tax” of credit card processing. Now, a first-of-its-kind law in Illinois is targeting a specific point of contention: the fees financial institutions charge on the tax and tip portions of a customer’s bill—money that merchants collect but never actually keep.
The Interchange Fee Prohibition Act is set to take effect on July 1, sparking a high-stakes battle between the state’s retail sector and the global financial infrastructure. At its core, the legislation aims to prevent banks and credit card companies from profiting off funds that are destined for the government or service staff.
- The Mandate: Financial institutions are prohibited from charging “swipe” (interchange) fees on the tax and tip portions of consumer transactions.
- Anti-Circumvention: The law bans banks from recouping these lost fees by increasing charges in other areas.
- Financial Impact: The prohibition is estimated to reduce revenue for banks and credit unions from retailers by approximately 10%.
- The Conflict: Banks claim the global payment system cannot technically discern tax and tips, while retailers argue it is a simple coding update.
The Mechanics of the Interchange Fee Prohibition Act
Interchange fees, commonly known as “swipe fees,” are the costs merchants pay to credit card networks and issuing banks every time a customer slides or taps a card. While these fees are standard for the base price of goods and services, the Illinois legislature determined that applying these fees to taxes and tips is an unfair burden on small businesses.
Under the new law, financial institutions cannot charge these fees on the non-revenue portions of a bill. This means if a customer leaves a 20% tip and pays a 10% sales tax, the bank cannot take a percentage of that 30% total. This shift directly protects the margins of restaurants and service-based businesses that operate on razor-thin profits.
“Credit Card Chaos” vs. “Complete Fabrication”
The implementation of the act has triggered a multi-million-dollar lobbying fight, with two starkly different narratives emerging regarding the technical feasibility of the law.
The Financial Institutions’ Perspective
The Electronic Payments Coalition—representing banks, credit unions, and card companies—warns that the law could lead to “credit card chaos.” They argue that the global payment ecosystem is not designed to distinguish between the total transaction amount and its individual components (tax, tip, and base price).
Ashley Sharp of the Illinois Credit Union Association stated that “the global payment system is not set up to where any one party to a transaction can make this happen on their own,” noting that multiple parties are involved in every electronic transaction. The coalition suggests that if the law isn’t repealed, card companies might stop serving Illinois entirely or drastically alter how consumers interact with merchants.
The Retailers’ Perspective
The Illinois Retail Merchants Association dismisses these claims as a “complete fabrication.” Retailers argue that credit card companies already track the necessary data to separate taxes and tips and that implementing the law would require nothing more than a mere coding change.
The Broader Economic Impact
The stakes are high for the financial sector. Industry data suggests that the tax and tip prohibition would shave roughly 10% off the revenue that credit unions and banks receive from retailers via interchange fees. This loss of revenue is the primary driver behind the aggressive lobbying efforts to repeal the act before its July 1 deadline.
For the state’s merchants, however, the law represents a victory in the ongoing struggle to lower the cost of doing business. By removing fees on money that doesn’t stay in the business’s pocket, the act effectively lowers the overhead for thousands of local enterprises.
What’s Next for the Payment Industry?
As the July 1 deadline approaches, the industry is watching Illinois as a test case. If the Interchange Fee Prohibition Act is successfully implemented without the predicted “chaos,” it could provide a blueprint for other states to challenge the pricing power of credit card giants.
The outcome will likely depend on whether the courts or the legislature side with the technical warnings of the Electronic Payments Coalition or the efficiency claims of the Illinois Retail Merchants Association. Regardless of the result, the friction between traditional banking revenue models and merchant sustainability has reached a breaking point.
