The drama over debit and credit card payments in Illinois got a little hotter last month when Sen. Dick Durbin (D-IL) issued a press release in support of the controversial Illinois Interchange Fee Prohibition Act. This is the state law passed late last spring that prevents issuers from charging interchange fees on the collection of taxes and gratuities. The law becomes effective July 1, 2025, and anyone who collects interchange on tax and tip payments will be subject to fines of up to $1,000 per transaction.
