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.
Things to know about this example
- Net income was estimated with Alaska's standard assumptions (single filer, 2026 tax year). Your actual taxes may differ.
How Alaska works it out
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.
