CO HB1154

Prohibits charging interchange fees on the portion of credit or debit card transactions that represents state, local, or district taxes.

Makes it unlawful to circumvent this prohibition by increasing interchange fees on the non-tax portion of transactions to compensate for lost revenue.

Allows the Attorney General or District Attorneys to bring civil actions with penalties of $1,000 to $5,000 per intentional violation, plus potential injunctive relief without proving inadequacy of other remedies.

Permits individuals who paid prohibited interchange fees to recover the greater of actual damages or $500 per violation.

Includes a 2-year grace period allowing existing contracts and software to continue unchanged through June 30, 2017, after which the prohibition applies to all transactions.
