How Arizona calculates child support
Arizona uses the income shares model: the schedule gives the basic obligation for the parents' combined monthly income, and each parent is responsible for their share.
Gross income from almost all sources counts, before taxes. Spousal maintenance paid is deducted and maintenance received is added; support paid for other children is deducted, and a parent's income may be reduced for other children living with them.
The parenting time table gives a percentage for the number of parenting-time days a year, from 20 days. That percentage of the basic obligation (plus the older-child adjustment) is subtracted from the share of the parent who has the time. With essentially equal time both parents get the top percentage and the parent with the larger amount pays.
A self-support reserve protects the paying parent: 80% of full-time earnings at the Arizona minimum wage of $15.15 an hour. Support can't take the paying parent's income below it. Amounts under the $8 monthly clearinghouse fee are not ordered.
The basic obligation goes up by 10% for each child aged 12 or older, shared across the children. The children's insurance premium and work-related child care are added and divided by income; the parent who pays them gets credit.
Support paid under other orders is deducted from income, and a parent may deduct the schedule amount for other children living with them, based on their own income.
The schedule runs to $30,000 of combined income a month. Above that the top amount applies unless a party asks the court for more.
Income shares are rounded to four decimal places and the final amount to the nearest dollar.
