Net Operating Losses on Corporate Income Tax Returns
PURPOSE: This rule explains the proper Missouri income tax
treatment of net operating losses by corporations.
(1) Federal Taxable Income Less Than Zero (0). Federal taxable
income is the starting point for computing a corporation’s
Missouri taxable income. Federal taxable income, as it is used
to compute a corporation’s Missouri taxable income, may be a
positive figure, a negative figure, or zero.
(2) Net Operating Loss (NOL).
(A) Taxpayers who file a consolidated Missouri return must
treat NOLs identically on the federal and Missouri returns.
(B) Taxpayers who file separate federal and Missouri returns
must treat NOLs identically on the federal and Missouri returns.
(C) Consolidated Federal and Separate Missouri Return.
Taxpayers who file consolidated federal and separate Missouri
returns shall compute separate federal taxable income as if
each member filed a separate federal return with the limitation
that the taxpayer shall be bound by the election to carry losses
forward or backward made on the consolidated return. If there
is a consolidated gain, then the Missouri taxpayer may elect
to carry loss backward or forward to the extent allowed under
Internal Revenue Code section 172.
(D) Notwithstanding the foregoing subsections of section (2)
of this rule, to the extent an NOL is carried backward for more
than two (2) years or carried forward for more than twenty (20)
years on the federal income tax return, that amount of the NOL
generally must be added to federal taxable income in arriving
at Missouri taxable income pursuant to section 143.121.2(4),
RSMo. Any amount of NOL taken against federal taxable income
but disallowed for Missouri income tax purposes under section
143.121.2(4), RSMo, may be carried forward and taken against
any income on the Missouri corporate income tax return for a
period of not more than twenty (20) years following the year of
initial loss.
(3) Recomputation of the Federal Income Tax Deduction
for Separate Missouri Return Filers to Reflect Consolidated
Return NOL. Taxpayer’s federal income tax deduction shall be
determined as follows. First, a fraction shall be created, the
numerator of which is the taxpayer’s original federal taxable
income reduced by its pro rata share of the consolidated loss
and the denominator of which is the original consolidated
federal taxable income reduced by total consolidated loss.
Next, total federal income tax of the consolidated group
after deduction of the net operating loss is multiplied by the
fraction, and then multiplied by fifty percent (50%), to arrive at
the adjusted federal income tax deduction.
(A) Example: 2014 consolidated loss of $75,000 carried back
to 2012.
First, allocate the loss to the loss companies.

Third, multiply the resulting adjusted federal income tax liability of the taxpayer by fifty percent (50%).
(B) Actual separate return loss will be used to compute
separate return federal taxable income.
(4) Leaving a Consolidated Group. A former member of a
consolidated group who filed a separate Missouri return
must recompute its federal income tax deduction to reflect
any decrease in consolidated federal income tax liability
attributable to an NOL carry back by the group and to reflect
any change in its relative share of federal income tax liability
attributable to the net operating loss carry back by the group.
(5) Taxpayers who elect a proper method of computing the
federal income tax deduction for a particular year shall
continue to use that method to compute the effect of NOL on
the federal income tax deduction for that year, regardless of
the method used in the year of the loss.
(6) When the filing status or combination for the Missouri
return for any taxable year is different from the federal filing
status or combination for that taxable year, the taxpayer must
follow the federal Internal Revenue Code (IRC) as it would apply
to the facts and circumstances for the Missouri return. Under
no circumstances may the same loss or deduction be used
more than once for Missouri purposes. A taxpayer claiming an
NOL deduction shall provide a schedule identifying the source
of each loss or deduction. If a corporate member of an affiliated
group incurs an NOL arising from a loss year for which such
member files a separate Missouri return or no Missouri return,
then that NOL cannot be carried to a consolidated Missouri
income tax return for a different tax year (the carryover tax
year), except insofar as that particular NOL is carried forward
or backward and actually deducted on the affiliated group’s
consolidated federal income tax return for that carryover
tax year, as reflected in the affiliated group’s federal taxable
income for that carryover tax year.
(7) If a corporation derives only part of its income from sources
within Missouri, its Missouri taxable income shall only reflect
an apportioned amount of the NOL deduction, consistent with
section 143.455.19, RSMo.
(8) The loss year referred to in section 143.431.4, RSMo, may
include the loss year of another taxpayer if the NOL occurred
in a loss year of another taxpayer. For example, in the situation
of a corporate merger where the taxpayer whose loss year gave
rise to the NOL did not survive the merger, the net operating
loss addition modification must still be computed by reference
to the addition and subtraction modifications for the loss
year of the corporation that did not survive the merger. For
purposes of section 143.431.4, RSMo, if more than one (1) net
operating loss addition modification must be computed for a
given tax year, the net operating loss addition modifications
are computed in the same order that the net operating losses
are used as net operating loss deductions for federal income
tax purposes.
(9) Notwithstanding any provision of this rule to the contrary,
nothing in this rule shall be interpreted or construed as
incorporating by reference any rule, regulation, standard, or
guideline of a federal agency.
