Illinois Businesses Were Promised Lower Card Fees — The Date Just Moved to 2027

If you run a restaurant, bar, or retail shop in Illinois and you've been waiting for a break on credit card processing costs, keep waiting. The Illinois General Assembly has delayed the state's Interchange Fee Prohibition Act for the second time, pushing the effective date from July 1, 2026 to July 1, 2027. For small business owners who have watched swipe fees eat into already-thin margins, the relief they were promised two years ago has now slipped another full year down the road — and even then, it may not apply to most of their transactions.

What the Law Was Supposed to Do

Illinois passed the Interchange Fee Prohibition Act in 2024 as a first-in-the-nation measure meant to stop banks and card networks from charging interchange fees on the tax and tip portions of a credit or debit card transaction. Right now, when a customer pays $110 for a $100 meal plus tax and tip, the merchant's bank pays an interchange fee to the customer's card-issuing bank on the full $110 — not just the $100 that actually goes to the business. That fee, typically 2% to 3%, is charged on money the business never keeps.

For restaurants and retailers running on tight margins, that adds up fast. Swipe fees are already one of the largest operating costs many small businesses face, often ranking just behind labor. The law was championed by restaurant and retail trade groups specifically because it would have carved tax and tip amounts out of the fee calculation, a change that could meaningfully lower processing costs for any business that takes card payments and charges sales tax.

Why It Keeps Getting Delayed

The law has been fighting a two-front battle since it passed. On the legislative side, lawmakers have now pushed the effective date back twice — first from 2025 to July 2026, and now from July 2026 to July 2027 — under pressure from banking industry groups who argue the law is unworkable and conflicts with federal rules on how card transactions are processed.

On the legal side, the Illinois Bankers Association, the American Bankers Association, and several credit union groups sued the state to block the law entirely. That lawsuit has already produced a partial win for the banks: a federal court entered an injunction exempting national banks, federally chartered banks, out-of-state state banks, and payment card networks from the interchange fee limitation. According to industry estimates, that injunction alone removes roughly 90% of Illinois card transactions from the law's reach, even before accounting for the new one-year delay. The Office of the Comptroller of the Currency has separately issued an order asserting that federal law preempts the state measure for the institutions it regulates, adding another layer of legal uncertainty about whether any version of the law survives in its current form.

What's left, for now, is a much narrower rule that would apply only to Illinois-chartered state banks and credit unions — and only starting in mid-2027, assuming the law isn't struck down entirely before then.

What This Means for Your Business Right Now

If you budgeted for lower processing costs starting this July, you need to reset that expectation. Swipe fees on tax and tip amounts are not going away in 2026, and given the pending litigation, it's not guaranteed they'll disappear in 2027 either. A few practical takeaways:

• Keep your current processing cost assumptions in place for at least the next 12 months. Don't build pricing or margin projections around fee relief that isn't coming this year.
• Ask your payment processor directly which card-issuing banks and networks your transactions actually run through. Since the exemption applies bank-by-bank, your real-world savings — whenever the law does take effect — will depend on which banks issued the cards your customers use, not just where your business is located.
• If swipe fees are a significant cost line for your business, revisit your profit and loss statement to see exactly how much you're losing to interchange fees on tax and tip amounts specifically, so you know precisely what's at stake if and when the law eventually takes hold.
• Consider whether a surcharge or minimum purchase policy for card payments makes sense for your business in the meantime — many states, including Illinois, allow merchants to pass along a portion of card costs to customers, subject to card network rules and disclosure requirements.

The Bigger Picture: This Fight Isn't Just in Illinois

Illinois was the first state to pass this kind of law, but it won't be the last to try. According to the Electronic Transactions Association, at least a dozen other states — including California, Colorado, Nevada, Texas, and Vermont — have introduced similar bills to strip interchange fees off tax and tip amounts. Illinois' experience is likely to shape how those bills are written, especially the exemptions carved out for federally regulated banks.

At the federal level, Senator Dick Durbin of Illinois has also continued pushing the Credit Card Competition Act, a bill that would require banks issuing cards to offer at least two competing networks for processing, aimed at driving down fees through competition rather than a direct prohibition. That bill has been attached to and then stripped from other legislation multiple times and has not become law, but it signals that swipe fee reform remains a live issue in Congress, not just in state capitals.

For now, the practical reality for Illinois business owners is this: nothing changes in your processing costs this year, the promised 2026 relief is now 2027 relief at the earliest, and even that later date only covers a fraction of your transactions given the current court rulings. If you're managing a business bank account and reconciling processing fees monthly, it's worth setting a calendar reminder to revisit this story next spring, since another legislative session — and another possible delay — will happen before the new effective date arrives. In the meantime, reviewing how your business bank account and merchant services are set up can help you spot which fees are negotiable with your processor directly, independent of what state law eventually requires.
