(1) For each taxable year an affiliated group of corporations
filing a federal consolidated income tax return does not file a
Missouri consolidated income tax return, the federal income
tax deduction of a member of the affiliated group shall be
determined by applying the formula set forth as follows:
(A) The group’s consolidated federal income tax liability
under Chapter 1 of the Internal Revenue Code (IRC) for the same
taxable year for which the Missouri return is being filed after
reduction for all credits on the return, except for the credit for
the overpayment of any federal tax and the credits allowed by
the IRC of 1986 by Section 31 (tax withheld on wages), Section
27 (taxes of foreign countries and possessions of the United
States) and Section 34 (certain uses of gasoline and special
fuels) shall be multiplied by a fraction, the numerator of which
shall be the federal taxable income of the member in question
and the denominator of which shall be the sum of the federal
taxable incomes of each member of the consolidated group
with a positive federal taxable income; and
(B) The product computed in subsection (1)(A) shall be
multiplied by the apportionment factor of the member in
question calculated under section 143.455, RSMo, or such other
apportionment factor as is computed under the apportionment
method applicable to the member in question.
