Section 100
Section 100.2300 Illinois
Net Loss Deduction for Losses Occurring On or After December 31, 1986 (IITA
207)
a) In General - For taxable years ending on or after
December 31, 1986, IITA Section 207 provides for computation of Illinois
net losses for corporations (including Subchapter S Corporations), trusts,
estates and partnerships. If, after applying all of the modifications
provided for in IITA Sections 203(b)(2), 203(c)(2) or 203(d)(2) and the
allocation and apportionment provisions of IITA Article 3, the taxpayer's
net income results in an Illinois net loss, such loss shall be allowed as a
carryback or carryover deduction in the manner allowed under Section 172 of
the Internal Revenue Code, as in effect during the loss year for tax years
ending prior to December 31, 1999. For losses incurred in tax years ending on
or after December 31, 1999, the Illinois net loss is allowed as a carryback to
the 2 preceding taxable years and as a carryforward to the 20 succeeding tax
years. The rules for members of a unitary business group are set out in
Sections 100.2340 and 100.2350. Sections 100.2200 through 100.2250 which also
relate to net operating losses of unitary business groups are only applicable
to losses incurred in taxable years ending prior to December 31, 1986. Section
100.9410(f) sets forth the statute of limitations for reporting an Illinois
net loss carryback. An Illinois net loss deduction is not available for
individuals. Losses incurred by individuals are recognized for Illinois tax
purposes in the computation of adjusted gross income for federal tax
purposes.
b) Definitions
1) "Illinois net loss" means the amount of loss
determined under IITA Section 207. That is, it is the amount of loss, if
any, after applying the modifications and allocation and apportionment
provisions of the Act, as calculated for tax years occurring on or after
December 31, 1986.
2) "Illinois net loss deduction" means the deduction
which may be carried pursuant to IITA Section 207.
3) "Net operating loss" means either: The amount of
net operating loss determined for federal tax purposes; or for losses
occurring prior to December 31, 1986, the amount recognized for Illinois
tax purposes.
4) "Net operating loss deduction" means either: The
amount of deduction recognized for federal tax purposes; or for losses
occurring prior to December 31, 1986, the amount recognized for Illinois
tax purposes.
5) The following terms have the following meanings: NOL - Net
Operating Loss NOLD - Net Operating Loss Deduction corp. - corporation
Treas. - Treasury Reg. - Regulation Sec. - Section Apport. - Apportionment
Ill. - Illinois sep. - separate comb. - combined
c) Treatment of capital losses of corporations. The treatment of
capital losses is separate and apart from the rules governing Illinois net
losses and Illinois net loss deductions. Capital losses will continue to be
governed by federal provisions. For federal purposes, capital losses are
permitted only to the extent of capital gains and the carryback of capital losses
is permitted only to the extent of capital gains in the carryback year. Since
the federal carryback of capital losses changes federal taxable income,
Illinois claims for refund based on such a federal change are permitted
pursuant to IITA Section 506(b). A change in federal taxable income resulting
from a federal capital loss carryback would be given effect before applying an
Illinois net loss deduction to the same year.
