Liability for Combined Tax, Penalty and Interest
Section 100
TITLE 86: REVENUE
CHAPTER I: DEPARTMENT OF REVENUE
PART 100 INCOME TAX
SECTION 100.5250 LIABILITY FOR COMBINED TAX, PENALTY AND INTEREST
Section 100.5250 Liability
for Combined Tax, Penalty and Interest
a) Joint and several liability of members of a combined group.
The members of a combined group shall be jointly and severally liable for the
combined tax, penalty and interest computed in accordance with this Subpart
Q
, as well as the Uniform Penalty and Interest Act
and rules adopted pursuant to the UPIA at 86 Ill. Adm. Code 700.
b) Effect of intercompany agreements. No agreement entered into
by one or more members of a combined group with any other member of such group
or with any other person shall in any case have the effect of reducing the
liability prescribed under this Section.
c) Penalties. If a penalty is imposed under the IITA and the
UPIA with respect to a combined return year, the amount shall be based on the
combined tax liability or deficiency for the common taxable year.
1) For purposes of applying the penalties for failure to file a
return imposed by Section 3-3(a), Section 3-3(a-5) and Section 3-3(a-10) of the
Uniform Penalty and Interest Act (UPIA) [35 ILCS 735/3-3]:
A) A corporation which erroneously fails to join in the filing of
a combined return, but which timely files a separate Illinois income tax return
or joins in the timely filing of a combined return for another combined group,
shall not be subject to any penalty. In determining whether such separate or
combined return is timely filed, the separate taxable year of such corporation
or the common taxable year of the combined group such corporation erroneously
joined shall be used, rather than the common taxable year of the combined group
with which such corporation should have filed.
B) A corporation which erroneously fails to join in the filing of
a combined return, and which fails, without reasonable cause, to timely file a
separate Illinois income tax return or to join in the timely filing of a
combined return for another combined group, shall be subject to penalty
computed on the amount of tax shown (or required to be shown) due on the
combined return for its proper combined group. Because it is the duty of the
designated agent, acting on behalf of the combined group, to include such
corporation in the combined return, the members of the combined groups shall be
jointly and severally liable for the penalty.
C) A corporation which erroneously joins in the timely filing of a
combined return shall not be subject to penalty for failure to file a return.
2) For purposes of applying the penalty for failure to timely pay
tax imposed by UPIA Section 3-3(b), Section 3-3(b-5), Section 3-3(b-10)
, Section 3-3(b-15), Section 3-3(b-20) and Section
3-3(b-25)
[35 ILCS 735/3-3]:
A) In a case where a corporation erroneously fails to join in the
filing of a combined return for a common taxable year, neither that corporation
nor the combined group shall be subject to any failure-to-pay penalty under
UPIA Section 3-3(b)(1), Section 3-3(b-5)(1), Section 3-3(b-10)(1)
, Section 3-3(b-15), Section 3-3(b-20)(1), or Section
3-3(b-25)(1)
if timely payment is made of the tax shown on a separate
return filed by such corporation or on a combined return in which it
erroneously joins in filing for each taxable year ending with or within such
common taxable year. Unless there is reasonable cause for the failure of such
corporation to join in the filing of the combined return, such corporation and
the combined group may be jointly and severally liable for a penalty under UPIA
Section 3-3(b)(2), Section 3-3(b-5)(2), Section 3-3(b-10)(2)
, Section 3-3(b-15), Section 3-3(b-20)(2), or Section
3-3(b-25)(2)
for failure to pay any additional amount which would have
been shown on the combined return had such corporation been included.
B) A corporation which erroneously fails to join in the filing of
a combined return for a common taxable year and also fails to timely pay the
tax shown on a separate return it files or on a combined return in which it
joins in filing for each taxable year ending with or within such common taxable
year shall be subject to penalty under UPIA Section 3-3(b)(1), Section
3-3(b-5)(1), Section 3-3(b-10)(1)
, Section 3-3(b-15),
Section 3-3(b-20)(1), or Section 3-3(b-25)(1)
only for failure to pay
the tax shown on the return it actually files or joins in filing. Unless there
is reasonable cause for the failure of such corporation to join in the filing
of the combined return, such corporation and the combined group may be jointly
and severally liable for a penalty under UPIA Section 3-3(b)(2), Section
3-3(b-5)(2), Section 3-3(b-10)(2)
, Section 3-3(b-15),
Section 3-3(b-20)(2), or Section 3-3(b-25)(2)
for failure to pay any
additional amount which would have been shown on the combined return had such
corporation been included.
C) If a corporation erroneously joins in the filing of a combined
return, neither such corporation nor the combined group shall be subject to
penalty under UPIA Section 3-3(b)(2), Section 3-3(b-5)(2), Section 3-3(b-10)(2)
, Section 3-3(b-15), Section 3-3(b-20)(2), or Section
3-3(b-25)(2)
for failure to pay any tax required to be shown on a
separate company return and the combined group shall not be subject to penalty
under UPIA Section 3-3(b)(2), Section 3-3(b-5)(2), Section 3-3(b-10)(2)
, Section 3-3(b-15), Section 3-3(b-20)(2), or Section
3-3(b-25)(2)
for failure to pay any increase in tax resulting from the
exclusion of such corporation from the combined group if the tax timely paid
with the original combined return exceeds the total tax required to be shown on
the correct returns.
3) For purposes of applying the negligence penalty imposed by
UPIA Section 3-5 [35 ILCS 735/3-5] or the fraud penalty imposed by UPIA Section
3-6 [35 ILCS 735/3-6] in any case in which a corporation erroneously joins or
fails to join in the filing of a combined return, the penalty may be imposed on
any deficiency resulting from such error, without taking into account any
overpayment which may have resulted from the error.
Example.
Corporations A, B and C meet all the requirements of a unitary business group,
except that Corporations A and B are financial organizations which cannot be
included in the same unitary business group as Corporation C, a manufacturer.
On a separate-return basis, Corporation A has an Illinois net loss of $500,
Corporation B has Illinois net income of $300 and Corporation C has Illinois
net income of $700. Corporations A and C file a combined return reporting combined
Illinois net income of $200, while Corporation B files a separate return
reporting Illinois net income of $300. On audit, the Department corrects the
liabilities by combining Corporations A and B, which eliminates Corporation B's
separate return income and entitles them to a refund of the taxes paid by
Corporation B, and by determining a separate return deficiency for Corporation
C. If the combination of Corporations B and C on the original return was due
to negligence or an intent to defraud, Corporation C will be subject to the
applicable penalty on its entire deficiency without regard to the overpayment
made by Corporation B.
4) For purposes of applying the penalty for failure to pay
estimated taxes under IITA Section 804, see Section 100.5230 of this Part.
d) Interest. If interest is imposed under the IITA, at the rate
determined under the UPIA, with respect to a combined return year, the amount
shall be based on the combined tax liability or deficiency for the common
taxable year. For purposes of computing any combined overpayment or
underpayment on which interest is imposed:
1) in a case in which one or more corporations erroneously failed
to join in the filing of the combined return, all payments, credits and other
amounts collected from such corporations which are properly attributable to the
common taxable year shall be treated as having been paid by the combined group
for such common taxable year; and
2) in a case where one or more corporations are erroneously
included in a combined return, the designated agent may allocate to each such
corporation some or all of the payments, credits and other amounts collected
from the combined group which are properly attributable to the common taxable
year, and all overpayments and underpayments for such corporations and the
combined group will be computed in accordance with such allocation. The amount
of estimated tax payments allocated to each such corporation pursuant to this
subsection (d)(2) must be consistent with the amounts allocated to such corporation
under Section 100.5230(a) and (g) of this Part.
