Note: You cannot use Form EFT-1 to register with the Illinois Department of Revenue for authorization to make ACH Credit payments. You must use MyTax Illinois to register for ACH Credit authorization. At the MyTax Illinois login screen, select "Register for ACH Credit Payments" under the REGISTRATION tab. You will be contacted by the department after we process your ACH Credit authorization request. We will reject all attempts to use Form EFT-1 for this purpose. Using MyTax Illinois is the only method to submit an ACH credit request for authorization. 



If you have questions, contact our Electronic Payments Section at 217 782-6257.
