Credit card surcharge rules in Illinois allow businesses to pass credit card fees to customers, but only within a strict framework: the surcharge is capped at the lower of 3% or your actual cost of accepting the card, it must be disclosed at three separate points before checkout, and it cannot be applied to debit or prepaid cards. Getting any piece of this wrong exposes the business to civil penalties under the Illinois Consumer Fraud and Deceptive Business Practices Act, which can reach $50,000 per transaction where a court finds intent to defraud.
The Surcharge Cap Is Lower Than You Think
Visa and Mastercard both cap credit card surcharges at 3% of the transaction amount. That ceiling took effect on April 15, 2023, when both networks lowered the previous 4% limit. The 3% figure is the number most businesses remember, and it’s the number most point-of-sale systems get programmed to.
The problem is that 3% is not actually your limit. Your surcharge cannot exceed your actual cost of accepting the card. If your effective merchant discount rate is 2.4%, then 2.4% is your ceiling, not 3%. Pocketing the difference violates card network rules and can support a deceptive-practices claim under Illinois law. Before you set a rate, look at your processor statement and use the lower of the two numbers.
What You Must Disclose, and Where
You must tell the customer about the surcharge at three points before the transaction is complete:
- At the entrance to your business, or on the landing page of your website
- At the point of sale
- On the receipt itself, as a separate line item rather than folded into the total
These requirements come from card network rules. Visa additionally requires that the surcharge amount travel in a dedicated data field within every transaction message, so your payment system has to transmit the surcharge separately from the purchase price.1Visa.

Debit and Prepaid Cards Are Off Limits
Surcharges apply to credit cards only. You cannot surcharge a debit card or a prepaid card, and it doesn’t matter whether the customer runs it as “credit” at the terminal or enters a PIN. The card itself decides eligibility, not the processing path.1Visa. Surcharging Credit Cards Q&A for Merchants
This is where hardware matters. If your point-of-sale system applies a flat surcharge to every card without identifying its type, you will eventually surcharge a debit transaction, and that violates both card network rules and federal law. Any business planning to surcharge needs payment software or hardware that identifies card type before the fee is added.
Register With Your Acquirer 30 Days Before You Start
You cannot begin surcharging on a Monday because you decided to on a Friday. Mastercard requires at least 30 days’ written notice to both Mastercard and your payment processor (acquirer) before you turn on a surcharge program.3Mastercard. Merchant Surcharge FAQ Visa dropped the requirement to notify Visa directly as of April 15, 2023, but the 30-day notice to your acquirer still applies.
Skipping this step is not just paperwork. Networks monitor surcharging activity, and merchants who surcharge without proper registration risk fines, higher processing fees, or termination of their merchant account. The registration process also forces you to document your surcharge percentage against your actual cost of acceptance, which becomes your paper trail if questions come up later.
Cash Discounts Are a Different Legal Structure
Some Illinois businesses avoid surcharge rules by offering a cash discount instead. From the customer’s view the two look similar, but they’re treated differently under the law. A surcharge adds a fee on top of the listed price when someone pays by credit card. A cash discount starts from a higher listed price and reduces it when someone pays with cash, check, or debit.
Federal law protects the right to offer cash discounts and blocks card networks from interfering, as long as the discount is available to all customers and clearly disclosed. The framing also affects sales tax in many jurisdictions, since a surcharge can be treated as part of the taxable transaction while a cash discount can reduce the taxable amount. What the label cannot do is contradict the actual pricing. Calling a surcharge a “cash discount” while pricing from a lower base is itself a compliance risk.
Penalties Under the Consumer Fraud Act
Illinois has no standalone surcharge penalty statute. Improper surcharge practices are enforced through the Consumer Fraud and Deceptive Business Practices Act, and the penalty structure has two tiers that catch businesses off guard.
For a general violation, the court can impose a civil penalty of up to $50,000 total against the business. That’s a single cap for the whole course of conduct. If the court finds the business acted with intent to defraud, the ceiling changes to up to $50,000 per violation, so each improper transaction can be a separate $50,000 penalty.4Illinois General Assembly. 815 ILCS 505/7 For any business running credit card transactions in volume, the gap between those two tiers is the entire risk picture.
An additional penalty of up to $10,000 per violation applies when the victim is 65 or older, with those funds directed to the Department on Aging for senior center grants.4Illinois General Assembly. 815 ILCS 505/7 Beyond fines, the court can order injunctive relief, restitution to affected consumers, and even revoke a business’s license or charter to operate in the state. When restitution and civil penalties are both awarded, restitution takes priority.
How Enforcement Actually Starts
The Illinois Attorney General’s office runs consumer fraud enforcement, including surcharge cases. Under the Consumer Fraud Act, the Attorney General can bring an action whenever there is reason to believe a business is using or about to use an unlawful practice and pursuing the case serves the public interest.4Illinois General Assembly. 815 ILCS 505/7
The office’s tools reach well past filing lawsuits. It can issue subpoenas, hold investigative hearings, and seek preliminary injunctions to stop a surcharge practice while litigation is pending. In serious cases the office can ask a court to appoint a receiver, dissolve a domestic corporation, or terminate a foreign corporation’s right to do business in Illinois.
Most cases begin with consumers reporting unexpected charges to the Attorney General’s Consumer Protection Division. Even a small cluster of complaints can trigger an investigation, particularly when the pattern looks like systematic nondisclosure rather than isolated errors. A business that finds a surcharge compliance problem on its own is almost always better off self-correcting and documenting the fix than waiting.
What’s Changing: The IFPA and Pending Bills
Illinois passed a first-of-its-kind law called the Interchange Fee Prohibition Act (IFPA).5FindLaw. Illinois Statutes Chapter 815 Business Transactions 151/150-1 The IFPA does not regulate what you charge customers. It targets a different piece of the cost chain by prohibiting card issuers and networks from collecting interchange fees on the sales tax, excise tax, and gratuity portions of a transaction. Merchants have to transmit tax and gratuity amounts as part of the transaction data for the prohibition to apply.
The IFPA is scheduled to take effect July 1, 2026. A federal court has upheld it as applied to card networks, Illinois-based banks, and credit unions, but granted preliminary injunctions for nationally chartered banks and out-of-state banks, finding that federal banking law likely preempts the state statute as to those institutions. Card issuers that violate the law after receiving proper tax and gratuity documentation face a $1,000 per transaction civil penalty if they fail to credit the merchant within 30 days.
For Illinois merchants, the IFPA doesn’t change your right to surcharge. It could lower your interchange costs on the tax and tip portions of each sale, which in turn lowers the maximum surcharge you can legally impose, because your surcharge can never exceed your actual processing cost. Payment systems that separate and transmit tax and gratuity data at the transaction level will be a practical requirement.
On the legislative side, Illinois lawmakers have introduced bills that would tighten surcharging, though none have been enacted as of early 2026. Senate Bill 3259 in the 103rd General Assembly would have formally defined “credit card surcharge fee” and made it unlawful to charge extra fees for using cash or debit cards, treating violations as unlawful practices under the Consumer Fraud Act.6Illinois General Assembly. Illinois Bill SB3259 – Fee Surcharge Limits Senate Bill 1931, in the 2025–2026 session, would prohibit credit card surcharges unless the business also accepts cash for all transactions under $1,000. Both are still in early stages. Any business starting a surcharge program now should build in enough flexibility to change course if either bill, or something like it, advances.
