How Alaska calculates child support
Alaska multiplies the paying parent's adjusted annual income by 20% for one child, 27% for two, 33% for three and 3% more for each additional child. The other parent's income isn't used when one parent has the children most of the year. The yearly amount is paid in twelve equal monthly installments.
Adjusted annual income is total income from all sources, including the Permanent Fund Dividend, minus income tax, Social Security and Medicare tax, unemployment insurance tax, mandatory union dues and retirement contributions, and a few other listed deductions. When you enter gross pay, this estimate works out the taxes the way the Child Support Enforcement Division calculator does (a single filer with the standard deduction); your actual taxes may differ.
When each parent has the children at least 110 overnights a year (thirty percent), Alaska uses its shared custody formula: each parent's amount is multiplied by the other parent's share of custody, the difference is multiplied by 1.5, and the result can't be more than the paying parent's amount without shared custody.
If a parent's total income is $30,000 a year or less, adjusted income is the lower of the usual figure and total income minus $7,500. The minimum support is $50 a month, except in shared custody.
Work-related child care for these children is subtracted from the income of the parent who pays it. The children's health insurance premium is shared equally: the paying parent's support goes down by half the premium if they pay it, or up by half if the other parent pays it. Uninsured medical costs are split equally outside the monthly payment.
Court-ordered support for children of an earlier relationship is subtracted from income. For earlier children living with the parent, the parent subtracts what Alaska's percentage would be for those children on their own income.
Adjusted income above $138,000 a year isn't counted. The court can add more only if it finds that just and proper, given the children's needs and the parent's ability to pay.
Alaska works with yearly amounts to the cent; the monthly payment is the yearly amount divided by twelve.
Parenting time in Alaska
When each parent has the children at least 110 overnights a year (thirty percent), Alaska uses its shared custody formula: each parent's amount is multiplied by the other parent's share of custody, the difference is multiplied by 1.5, and the result can't be more than the paying parent's amount without shared custody.
| Overnights with Parent A | Guideline amount | Who pays |
|---|---|---|
| 0 | $1,128 a month | Parent A pays Parent B |

What is the child support for one child in Alaska on $50,000?
If Parent A earns $50,000 a year, Parent B earns $40,000 and the child lives mostly with Parent B, Alaska's guideline amount for one child is about $702 a month (Parent A pays Parent B). Courts can deviate from the guideline amount.
Does 50/50 custody mean no child support in Alaska?
Not necessarily. With about equal parenting time, 2 children, Parent A earning $60,000 and Parent B $40,000, the guideline amount is about $270 a month (Parent A pays Parent B). When each parent has the children at least 110 overnights a year (thirty percent), Alaska uses its shared custody formula: each parent's amount is multiplied by the other parent's share of custody, the difference is multiplied by 1.5, and the result can't be more than the paying parent's amount without shared custody.

When does child support end in Alaska?
Unless the order says otherwise, support ends when the child turns 18, marries, is legally emancipated, joins the armed forces and is no longer supported as a dependent, dies or is adopted. On a parent's motion, a court can continue support while the child is 18 if the child is unmarried, actively pursuing a high school diploma or equivalent technical or vocational training, and living as a dependent with a parent, guardian or designee. Past-due support remains collectible.
