I filed 10 days ago, and my return was accepted 9 days ago. I signed up for direct debit as my payment option on 4/11/19, but I need to change that to a payment plan. How can I go about doing that?
Yes, it is possible to cancel an auto debit and set up a payment plan.
You can cancel the auto withdrawal you set up when you filed your return by calling the IRS e-file Payment Services 24/7 at 1-888-353-4537. Be sure to wait 7 to 10 business days after your return was accepted before calling.
Cancellation requests must be received no later than 11:59 p.m. ET two business days prior to the scheduled payment date.
You can set up a payment plan with the IRS online: https://www.irs.gov/payments/payment-plans-installment-agreements
