§ How Arizona calculates support

Arizona uses the Income Shares Model adopted by the Supreme Court through Administrative Orders (current guidelines effective Jan. 1, 2022). Both parents' adjusted gross incomes are combined and matched to the Schedule of Basic Support Obligations; each parent pays a share proportional to income, with health insurance, childcare, and extraordinary costs added. Notable features: a parenting-time credit (reduces the obligation as overnights rise, up to 50% at 164+ days), a self-support reserve (80% of state minimum-wage earnings, about $2,100/mo in 2026), an older-child adjustment (+10% for age 12+), and Social Security derivative-benefit credits.

◈ Illustrative examples

Illustrative example

Illustrative example — two children, combined $6,000

Scenario: Parent A adjusted gross $3,600 (60%), Parent B $2,400 (40%); two children.

Walk-through: Combined $6,000 → schedule basic obligation ≈ $1,429/month. Parent A's 60% share ≈ $857/month before parenting-time and add-on adjustments.

Takeaway: Arizona splits the schedule amount by each parent's income percentage; parenting time and insurance/childcare adjust the final number.

Illustrative example

Illustrative example — parenting-time credit

Scenario: Same incomes, but the paying parent has 150 parenting days per year.

Walk-through: The parenting-time table reduces the basic obligation by about 32.5% before splitting; Parent A's payment drops accordingly.

Takeaway: More overnights mean a larger parenting-time credit in Arizona.

? Frequently asked questions

What is 'child support income' in Arizona?

A broad measure of gross income from any recurring source — wages, bonuses, self-employment, military pay, pensions, Social Security, unemployment, disability, and recurring gifts. Child support received for other children and means-tested benefits are excluded.

How does parenting time change the amount?

The Parenting Time Table reduces the basic obligation from 0% (under 20 days/year) up to 50% (164+ days). Credit is applied before splitting each parent's share.

What is the self-support reserve?

It equals 80% of monthly full-time earnings at the state minimum wage (about $2,100/month in 2026); the order cannot push the payor below it.

Is there an adjustment for older children?

Yes. The guidelines add 10% to the basic obligation for each child age 12 or older.

What if the child gets Social Security derivative benefits?

Those payments are credited against the paying parent's obligation month by month.
