How to make a Citi online payment

Citi® Double Cash Card – 18 month BT offer payments can be made online in one of two ways:

  • Make a Payment is for one-time payments. You’ll need to sign in to your account and then set your payment amount, payment method and date. You will then be able to confirm your payment and receive a confirmation code and an email notification that your payment was submitted.
  • Another option is to set up AutoPay for automatic payments to be deducted monthly on your due date. This is a good backup plan to never miss a payment, but you need to make sure that you have the available funds.

Note: You can schedule one payment per day within your current billing cycle, as well as up to four future payments beyond your current billing cycle.

Customers can also make payments by mail or phone.
