ACI Payments, Inc. (formerly Official Payments) is a leading digital bill payment provider that lets consumers pay federal and state taxes, utility bills, college tuition, and local government fees online, by phone, or via mobile app. It partners with the IRS, dozens of states, and thousands of municipalities and universities nationwide to process secure card and e-check payments.

Use Fluz to maximize rewards on the bills you pay through ACI Payments, like taxes, tuition, or utility bills. Instead of paying with your card directly on the site, buy a Fluz gift card for your exact payment amount and use it to complete the transaction, earning cashback on payments you have to make anyway. Since Fluz stacks with other rewards, you can layer this cashback on top of anything else you're earning. It's an easy way to turn mandatory tax and bill payments into an opportunity for extra savings.
