New Mexico’s child support guidelines, under § 40-4-11.1 NMSA and 8.50.108 NMAC (effective January 1, 2024), use an Appendix 1 schedule reaching $40,000 in combined monthly income across 772 rows, with a distinct self-support-reserve area below that. A 35% shared-responsibility threshold triggers Worksheet B with a 1.5 multiplier, instead of the standard Worksheet A.
