Can I use more than one credit card or debit card with Scheduled Payments/AutoPay?
Yes. . However, you are limited to one credit card or debit card for each payment schedule. For example, you may establish two separate payment schedules for a single payment obligation, e.g., an IRS Installment Agreement and use a different credit/debit card for each schedule. Also, different credit cards or debit cards may be used with different payment schedules set-ups that have been established for different Official Payments clients.
