To revoke or cancel an EFW payment, the taxpayer should contact the IRS E-File Payment Inquiry and Cancellation Service at 1-888-353-4537.
They should wait at least ten (10) days from when the IRS e-File return was accepted before calling. The caller should be prepared to provide the TIN (EIN or SSN), whether the payment is a business payment or individual payment, the exact payment amount (dollars and cents), and bank account number entered in the payment record. Cancellations must be made by 11:59 p.m. ET two business days prior to the scheduled payment date.
