N.M. Code R. § 3.3.4.9
APPORTIONMENT OF SECTION 7-2-5.2 NMSA 1978 EXEMPTION
B. For taxable years beginning in 1987, 1988 or 1989, apportionment shall be accomplished by reducing the individual's deduction for non-New Mexico income by an amount equal to the product of the maximum allowable amount for the individual's filing status and adjusted gross income multiplied by the percentage of non-New Mexico income computed on the individual's New Mexico income tax return or any schedules or attachments thereto.
(1) Example 1: X is a single individual over sixty-five years of age whose total adjusted gross income is $19,000. Thirty percent of X's adjusted gross income is non-New Mexico income. X must reduce X's non-New Mexico income by $2,100, computed as follows:
Maximum allowable amount for a single
individual with $19,000 AGI $ 7,000
30% x $7,000 x .30
Adjustment to non-New Mexico Income $ 2,100
(2) Example 2: A and B are married and file a joint return. A is over 65. B is 62 and blind. 10% of their $25,000 adjusted gross income is from outside New Mexico. A & B must reduce their non-New Mexico income by an amount of 1,600 computed as follows:
Maximum allowable amount per individual for a
married couple filing jointly with $25,000 AGI $ 8,000
Multiply by 2 since both individuals qualify x 2
$16,000
10% x $16,000 x .10
Adjustment to non-New Mexico Income $ 1,600
D. This version of this section (3.3.4.9 NMAC) is retroactively applicable to taxable years beginning on or after January 1, 1990.
