Section 105.500 Purpose
a) Form IL-8453 is the signature portion of the return. It must
be completed and signed by all appropriate parties before the return is
transmitted electronically. Form IL-8453 serves the following purposes:
1) Authenticates the return;
2) Serves as a transmittal for the associated non-electronic
documents that will be stapled to the declaration and sent to the Department,
when requested. Section 105.100(c) lists documents and forms to be attached to
Form IL-8453;
3) Authorizes the electronic return originator to file the return
electronically on behalf of the taxpayer;
4) Provides the taxpayer's written authorization to have the
refund directly deposited as designated on the form; and
5) Authorizes the Department to inform the electronic return originator,
or the transmitter, that the taxpayer's return has been accepted or rejected.
When rejected, authorizes the Department to identify the reasons for rejection.
b) Form IL-8453 does not serve as a power of attorney or as a
substitute for the information required on the electronic tax return.
c) Form IL-8453 cannot be used to submit forms or schedules which
are not listed in Section 105.100. Returns requiring forms that are excluded
from electronic filing must be filed on a paper Form IL-1040.
