Section 7-4-10 - Apportionment of business income.
7-4-10. Apportionment of business income.
A. Except as provided in Subsection B of this section, all business income shall be apportioned to this state by multiplying the income by a fraction, the numerator of which is the property factor plus the payroll factor plus the sales factor and the denominator of which is three.
B. For taxable years beginning prior to January 1, 2020, a taxpayer whose principal business activity is manufacturing may elect to have business income apportioned to this state by multiplying the income by a fraction, the numerator of which is the property factor plus the payroll factor plus twice the sales factor and the denominator of which is four. To elect the method of apportionment provided by this subsection, the taxpayer shall notify the department of the election, in writing, no later than the date on which the taxpayer files the return for the first taxable year to which the election will apply. The election will apply to that taxable year and to each taxable year thereafter until the taxpayer notifies the department, in writing, that the election is terminated, except that the taxpayer shall not terminate the election until the method of apportioning business income provided by this subsection has been used by the taxpayer for at least three consecutive taxable years, including a total of at least thirty-six calendar months. Notwithstanding any provisions of this subsection to the contrary, the taxpayer shall use the method of apportionment provided by Subsection A of this section for the taxable year unless:
(1) the taxpayer's corporate income tax liability for the taxable year, computed by the same method of apportionment used in the preceding taxable year, exceeds the corporate income tax liability for the taxpayer's immediately preceding taxable year; or
(2) the sum of the taxpayer's payroll factor and property factor for the taxable year exceeds the sum of the taxpayer's payroll factor and property factor for the taxpayer's base year. For purposes of this paragraph, "base year" means the taxpayer's first taxable year beginning on or after January 1, 1991.
C. For purposes of this section, "manufacturing" means combining or processing components or materials to increase their value for sale in the ordinary course of business, but does not include:
(1) construction;
(2) farming;
(3) power generation, except for electricity generation at a facility other than one for which both location approval and a certificate of convenience and necessity are required prior to commencing construction or operation of the facility, pursuant to the Public Utility Act [62-13-1 NMSA 1978]; or
(4) processing natural resources, including hydrocarbons.
