Title 86 - REVENUE
Part 107 - TELEFILING OF ILLINOIS INDIVIDUAL INCOME TAX RETURNS
Section 107.400 - Confirmation of TeleFile Returns

a) Upon successfully entering all the required return, form or schedule information using the number keys on a touch-tone telephone, the TeleFile Filer will be given a confirmation number by the automated voice prompt system.

b) TeleFile Filers must maintain a record of the confirmation number in order to establish that the returns, forms or schedules were received by the Department on the dates that the confirmation numbers were issued.

c) The date that the telephone call is completed and a confirmation number is issued by the automated voice prompt system is the received date for the return to which the confirmation number relates. Where a telephone call is initiated on one date and completed on another, the date that the telephone call is completed is the date of filing. The telephone call must be completed by 11:59 p.m. CST (with adjustments for Daylight Savings Time if applicable) on the due date of the return for the TeleFile filing to be considered timely.

d) TeleFile Filers cannot recall or intercept TeleFile filed returns after the returns have been confirmed as received. If TeleFile Filers wish to change any entries after a return has been confirmed, a paper amended return, Form IL-1040-X, must be filed with the Department. (See also 86 Ill. Adm. Code 100.9400(f)(3).)

e) When a TeleFile return has not been confirmed after several attempts, the TeleFile Filer should contact the Department for assistance by calling the telephone number provided in the IL-1040 booklet.

f) Unless a TeleFile return is confirmed as filed by the Department, it will not be considered a filed return.
