The Consumer Inflation Reduction and Tax Fairness Act aims to regulate interchange fees associated with electronic payment transactions, specifically addressing the treatment of tax and gratuity amounts. The bill defines key terms such as "acquirer bank," "merchant," "interchange fee," and "tax documentation," establishing a framework for how these entities interact during electronic transactions. Notably, it stipulates that issuers, payment card networks, acquirer banks, or processors cannot charge merchants interchange fees on the tax or gratuity amounts if the merchant provides this data during the authorization or settlement process. If the merchant fails to do so, they can submit tax documentation within 180 days to receive a credit for the interchange fees charged on those amounts.

Furthermore, the bill imposes civil penalties on entities that willfully manipulate interchange fees to circumvent these provisions, allowing aggrieved merchants to seek damages and refunds for unlawful fees. The Attorney General or local district attorneys are empowered to enforce these provisions, and any penalties collected will be allocated to the respective state or county general funds. The act also includes a severability clause, ensuring that if any part of the law is deemed invalid, the remaining provisions will still be enforceable.
