Paying your Citi credit card bill online is the fastest, most secure way to stay on top of your account. Whether you want to make a one-time payment or set up automatic payments, Citi’s online tools make it simple to manage your balance from anywhere — on desktop or mobile.

​
Why Pay Your Citi Card Online?

Paying online offers several advantages over mailing a check or paying in person:
  • Instant processing — payments post the same or next business day
  • 24/7 access — pay anytime, from anywhere
  • Payment history — track every transaction in one place
  • AutoPay — never miss a due date
  • Secure — protected by bank-grade encryption

​

Before you begin, make sure you have:
  • Your Citi Online User ID and Password
  • Your Citi credit card account number

Payment Tips

Pay Before the Due Date

Submit payments at least 1–2 business days before the due date to allow for processing.

Pay More Than the Minimum

Paying more than the minimum reduces interest charges and pays off debt faster.

Enable Alerts

Turn on due date and payment confirmation alerts in the app.

Keep Records

Save confirmation numbers and email receipts for at least a year.

​
Troubleshooting

Verify the bank account has sufficient funds and that the routing/account numbers are correct. Contact Citi if it still fails.
Log in and cancel or edit the payment before the cutoff time (usually 5 PM ET on the payment date).
Payments made before 5 PM ET typically post the same day. Payments after that post the next business day.
Yes. You can schedule payments up to 90 days in advance through Citi Online or the Mobile App.
