Illinois lets businesses add surcharges to credit card transactions, but the rules are a bit tighter here than in other states. Let’s dive into what Illinois business owners need to know about surcharging in 2024—plus a look at some big changes coming up that could help cut your processing costs.
Let’s start with the basics. Illinois does allow credit card surcharges, but with a few key limits:
If you’re running a business in Illinois, understanding these guidelines is crucial to stay compliant—and to know your options for keeping credit card fees in check.
Illinois has a pretty strict limit on surcharges: 1% of the transaction or your actual cost of processing the payment, whichever is lower. Sound straightforward? Let’s go over some examples to see how it plays out.
Example 1: When Processing Costs Are Higher Than 1%
In this case, even though processing costs are higher than 1%, Illinois law limits the surcharge to 1%, or $0.50.
Example 2: When Processing Costs Are Lower Than 1%
Here, your cost of processing the payment is less than 1%, so the surcharge cap defaults to your processing cost of $0.50.
For most Illinois businesses, processing costs usually exceed 1%, so you’ll likely be using the 1% cap regularly to cover a portion of your expenses.
Surcharging laws in Illinois cover all types of credit card transactions, whether in-person, online, or over the phone. To comply, businesses must notify customers before they pay if a surcharge applies to their credit card transaction. This rule falls under Illinois’s Consumer Fraud and Deceptive Business Practices Act, so it’s essential to get it right to avoid any issues.
The good news? Clear and honest communication about surcharges can actually help build trust with customers. A simple sign at checkout or a message during online checkout should do the trick.
On July 1, 2025, Illinois will start enforcing a groundbreaking new rule on interchange fees. The Illinois Interchange Fee Prohibition Act will prevent card networks and processors from charging interchange fees on tax and gratuity amounts.
Here’s how this new rule might look in action:
For many Illinois businesses, this change could lead to substantial savings on transactions involving tax and gratuity charges—like in the restaurant or hospitality industry.
While Illinois allows credit card surcharges, it’s one of the strictest states in terms of limits and transparency requirements. These rules protect consumers from unexpected fees and keep surcharges reasonable for everyone involved.
