The Illinois Department of Revenue accepts EFT Debit and EFT Credit payments of withholding taxes.

How to apply

The Illinois Department of Revenue requires some EFT users to complete and sign Form EFT-1 Authorization Agreement for Electronic Funds Transfer for approval before submitting tax payment files. Once approved, you will receive payment instructions and the date you can begin making payments. Please use this information to verify that all bank account information is correctly entered in the application prior to remitting any tax payments to your bank for processing. For more information about making EFT credit payments and to obtain the State of Illinois' Form EFT-1, please visit the Illinois Department of Revenue website and click the link for the Tax Professionals page.

Payment and other information

If you are paying via EFT, you are not required to file IL-501 payment forms. However, you are still required to file the IL-941 tax payment reconciliation forms on the regular due date for the particular tax period being paid.
