43-1029. Restoration of a substantial amount
held under claim of right; computation of tax


A. This section applies if:


1. An item of income was included in gross income for a prior taxable year or years
because it appeared that the taxpayer had an unrestricted right to the item.


2. A deduction would be allowable under the internal revenue code or this title for
the taxable year, without application of section 1341(b)(3) of the internal revenue code
or section 43-1021, paragraph 20, because after the close of the prior taxable year or
years it was established that the taxpayer did not have an unrestricted right to all or
part of the item.


3. The amount of the deduction exceeds three thousand dollars.


B. If all of the conditions in subsection A of this section apply, the tax imposed
by this chapter for the taxable year is an amount equal to the tax for the taxable year
computed without the deduction, minus the decrease in tax under this chapter for the
prior taxable year or years that would result solely from excluding the item or portion
of the item from gross income for the prior taxable year or years.


C. If the decrease in tax exceeds the tax imposed by this chapter for the taxable
year, computed without the deduction, the excess is considered to be a payment of tax on
the last day prescribed by law for the payment of tax for the taxable year and shall be
refunded or credited in the same manner as if it were an overpayment for the taxable
year.


D. Subsection B of this section does not apply to any deduction that is allowable
with respect to an item that was included in gross income by reason of the sale or other
disposition of stock in trade of the taxpayer, or other property of a kind that would
properly have been included in the inventory of the taxpayer on hand at the close of the
prior taxable year, or property that is held by the taxpayer primarily for sale to
customers in the ordinary course of the taxpayer's trade or business. This subsection
does not apply if the deduction arises out of refunds or repayments with respect to rates
made by a regulated public utility that is listed in section 7701(a)(33)(A) through (H)
of the internal revenue code, if the refunds or repayments are:


1. Required to be made by the government, political subdivision, agency or
instrumentality referred to in that section.


2. Required to be made by an order of a court.


3. Made in settlement of litigation or under threat or imminence of litigation.


E. If the exclusion under subsection B of this section results in:


1. A net operating loss for the prior taxable year or years for purposes of
computing the decrease in tax for the prior year or years under subsection B of this
section:


(a) The loss shall be:


(i) Carried over under this chapter to the same extent and in the same manner as
was provided under prior law for taxable years beginning on or before December 31, 1989.


(ii) Carried back and carried over to the same extent and in the same manner as
provided under section 172 of the internal revenue code for taxable years beginning from
and after December 31, 1989.


(b) No carryover beyond the taxable year may be taken into account.


2. A capital loss for the prior taxable year or years, for purposes of computing
the decrease in tax for the prior taxable year or years under subsection B of this
section:


(a) The loss shall be carried back and carried over to the same extent and in the
same manner as is provided under section 1212 of the internal revenue code.


(b) No carryover beyond the taxable year may be taken into account.


F. In computing Arizona taxable income for taxable years subsequent to the current
taxable year, the net operating loss or capital loss determined in subsection E of this
section shall be taken into account to the same extent and in the same manner as a net
operating loss or capital loss sustained for prior taxable years.
