How New Mexico calculates child support
New Mexico uses the income shares model: the schedule gives the support for both parents at their combined gross monthly income, and each parent is responsible for their share.
Gross income from almost all sources counts, before taxes, including alimony received. Means-tested public assistance such as TANF and SSI does not count. Alimony paid and court-ordered support paid for prior children are subtracted first.
New Mexico counts parenting time in twenty-four-hour days. When the children spend at least 128 days a year in each home, Worksheet B multiplies the schedule amount by 1.5, each parent keeps their share in proportion to their days, and the parent with the larger remaining share pays the difference.
The schedule has a built-in self-support reserve of $1,200 a month. If the paying parent's own income is in the shaded low-income area (up to $1,800 a month for one child and $3,100 for six), the support is the schedule amount on that parent's income alone, with no add-ons. This applies only when the paying parent has less than shared time.
The children's health and dental insurance premium, work-related child care and uninsured medical costs above $100 per child a year are added to the schedule amount and divided by income share; each parent gets credit for what they pay.
Court-ordered support a parent pays for prior children is subtracted from that parent's gross income. The guidelines allow a reasonable amount for prior children living with a parent but don't set it, so the estimate doesn't include it.
The schedule runs to $40,000 of combined monthly income. Above that, the guideline is the amount at $40,000 plus 5.4% (one child) to 11.6% (six children) of the income over $40,000.
Combined income is rounded to the nearest $50 to find the schedule row; worksheet amounts are kept to the cent and the shared-time percentages are whole percents.
Parenting time in New Mexico

When does child support end in New Mexico?
In New Mexico, child support is set for unemancipated minor children, and a minor child is one younger than 18. Support continues until high school graduation for a child who is 18 only by age, is under 19 and is still attending high school. The court may order support for education after high school only under a written agreement between the parents. We didn't locate an official source on support for an adult child with a disability.
