ACH Credit is an electronic payment method that you may use to pay tax liabilities. You instruct your financial institution to transfer the funds from your account to ours. We then apply the payment to your tax liability. Payments are made using the Tax Payment (TXP) Banking Convention in the addendum record of a CCD+ formatted record.
If you are mandated or interested in paying your tax by this method voluntarily, 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.
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. 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.
