86 Ill. Adm. Code 100.5180
Composite Returns: Overpayments and Underpayments
Section 100.5180 Composite Returns: Overpayments and
Underpayments
a) When
an authorized agent has made an error in determining the amount of any item of
income, deduction, addition, subtraction or credit reported on a composite
return, the authorized agent shall file an amended return to correct the error
and claim a refund or credit, or pay the liability, for any person included on
the composite return.
b) For
taxable years ending on or after December 31, 2008, a partnership or subchapter
S corporation may report the changes in liabilities of its partners or
shareholders and pay the resulting underpayments, on behalf of its partners and
shareholders, whether or not a composite return was filed for the taxable year
or any specific partner or shareholder was included on that composite return. A
partnership or subchapter S corporation may claim a refund or credit of any
amount it paid on behalf of its partners or shareholders under Section
100.5100, subsection (a) or this subsection, but may not claim a refund or
credit of any amount paid to the Department by a partner or shareholder.
c) If
the amount of tax properly reportable on any return filed under Section
100.5100 or any original or amended return filed under subsection (a) or (b) is
not reported and timely paid, the Department may issue a notice of deficiency
to the authorized agent with respect to that underpayment and any associated
penalties and interest and may issue notices of deficiency to the partners or
shareholders, provided that:
1) The
Department may not collect the underpaid amount of tax, including associated
penalties and interest, more than once, and, if claims for refund or credit of
any amount collected more than once are timely filed by both a partner or
shareholder and the authorized agent, any amount collected from that partner or
shareholder in excess of the underpayment attributable to that partner or
shareholder shall be refunded or credited to that partner or shareholder rather
than to the authorized agent; and
2) No
penalty for failure to timely file a return or pay the amount of tax due shall
be assessed against a partner or shareholder who had timely requested the
authorized agent in writing to file composite original or amended returns and
pay tax on his or her behalf under this Part, and had no knowledge that the
authorized agent would not comply with that request prior to the earlier of the
date of filing or the due date (including extensions) for filing the partner's
or shareholder's return.
