Alaska Child Support: Calculation, Orders, and Enforcement

Child support in Alaska is set by a percentage-of-income formula under Civil Rule 90.3, administered mostly by the Child Support Services Division (CSSD), and paid until the child turns 18 (or 19 if the child is still in high school or equivalent vocational training and living with the custodial parent). How much you pay or receive depends on the noncustodial parent’s adjusted annual income, how many children are covered, and how parenting time is split.

How the Amount Is Calculated

The starting point is the noncustodial parent’s adjusted annual income. That figure is total income from all sources minus mandatory deductions: federal, state, and local income taxes, Social Security and Medicare, mandatory union dues, required retirement contributions, the parent’s own health insurance premiums (capped at 10% of total income), and work-related child care costs for the children covered by the order.¹ “Total income from all sources” is read broadly: wages, self-employment earnings, investment returns, rental income, and most government benefits all count.

Adjusted income is then multiplied by a set percentage based on the number of children:

One child: 20%
Two children: 27%
Three children: 33%
Each additional child: add 3%

Those percentages apply directly in a primary custody arrangement.¹ There is a ceiling on the income that gets counted: adjusted annual income above $138,000 is excluded from the calculation unless the other parent shows evidence supporting a higher figure.²

How Custody Time Changes the Number

Parenting time reshapes the formula. Alaska recognizes four arrangements.

Primary custody is when the children live with the other parent less than 30% of the year. The standard percentages above apply directly to the noncustodial parent’s adjusted income.

Shared custody is when each parent has the children at least 30% but no more than 70% of the year. An overnight generally requires the child to sleep at that parent’s home, and 30% works out to roughly 110 overnights per year.³ Under shared custody, both parents’ incomes and the actual split of parenting time feed into the formula, which usually produces a lower obligation than a primary custody calculation.

Divided custody applies when different children from the same parents live primarily with different parents. Each parent’s obligation is calculated separately for the child living with the other parent, and the two amounts are offset into a single net payment. Hybrid custody covers situations where at least one child is in shared custody while another is in primary custody with one parent.

When a Court Can Deviate From the Formula

The Rule 90.3 amount is a presumption, not a hard cap. A court can go higher or lower if the standard number would be clearly unjust, but the bar is real: the parent asking for a deviation has to show by clear and convincing evidence that the formula amount would cause manifest injustice. If the court grants a deviation, it must put its reasons in writing, state the amount the formula would have produced, and estimate the value of any property transferred in place of ongoing support.¹

Facts that sometimes justify a deviation include unusually high medical expenses for a child, significant prior debts that predate the relationship, or a paying parent whose income is so low that the guideline number leaves them unable to meet basic needs. The court can also weigh the custodial parent’s income when deciding whether to adjust.

What Happens if a Parent Is Unemployed or Underemployed

Losing a job or taking a pay cut does not automatically lower support. If a court finds a parent voluntarily and unreasonably unemployed or underemployed, it can impute income, meaning support is calculated on what the parent could be earning rather than what they actually earn.

Before imputing income, the court looks at:

Whether the reduced income is temporary or reflects a long-term choice
Work history and job skills, including education and past earnings
Age, health, and any criminal record limiting employment options
Local job market conditions and the parent’s record of seeking work
Whether the children benefit from the decision, such as a parent returning to school for a credential that will raise future earnings

Income cannot be imputed to a parent who is physically or mentally unable to work, or who is caring for a child under two years old to whom both parents owe a legal responsibility.¹

Health Insurance and Medical Expenses

Every Alaska child support order has to address health care. The court is required to order health insurance for the children if coverage is available to either parent at a reasonable cost and is accessible to the children. Insurance is presumed reasonable if it costs no more than 5% of the adjusted annual income of the parent who would carry it.¹ Before ordering private coverage, the court also considers whether the children qualify for services through Indian Health Service or another existing plan.

The cost of the children’s insurance is split equally between the parents unless the court finds good cause to divide it differently. Uncovered medical expenses (copays, deductibles, treatments insurance won’t pay for) are also split equally. A parent who pays an uncovered expense is entitled to reimbursement of the other parent’s share within 30 days of submitting the bill and any insurance explanation of benefits.¹ Federal rules mirror this: state child support agencies must include health coverage in every new or modified order when it is available at reasonable cost, or a cash medical support provision until coverage becomes available.⁴

Getting an Order in Place

Alaska has two paths to a legally binding support order. Which one you use usually depends on whether you already have another family case running.

Through CSSD

The CSSD can set up an order without any court hearing. A parent files an application for services, a caseworker verifies both parents’ income, and the agency issues an administrative order based on Rule 90.3. If the parents were not married, the CSSD can establish paternity as part of the same process.

Through the Superior Court

Parents already in a divorce, dissolution, or custody case get their support order from the Superior Court. The court has to issue a support order alongside any custody determination. Both parents file a Child Support Guidelines Affidavit (Form DR-305) laying out income and allowable deductions so the court can run the Rule 90.3 calculation.⁵

Enforcement When Payments Stop

Unpaid support builds into arrearages, and the CSSD has broad collection authority without going back to court for most tools.

Wage Withholding

The most common method is automatic income withholding. The employer receives a withholding order and deducts support from the paycheck before the parent sees it. Alaska caps withholding at 40% of net disposable earnings, or 50% when health insurance costs are included.⁶ Federal law sets its own ceilings: 50% of disposable earnings if the paying parent supports another spouse or child, 60% if not, plus an extra 5% in either case when arrearages exceed 12 weeks.⁷

Other Collection Tools

Permanent Fund Dividend interception. The PFD is not exempt from child support collection and can be seized to cover arrearages.⁸
Federal and state tax refund interception.
Liens on real property and other assets, and direct bank account levies.
Suspension of driver’s licenses, professional licenses, and recreational licenses.

Contempt and Criminal Nonsupport

For persistent or willful refusal to pay, the custodial parent can ask the court to hold the other parent in contempt, which can lead to fines or jail. Alaska also has a separate criminal nonsupport statute for the most egregious cases. These are rare next to administrative enforcement, but they carry real consequences.

Changing an Existing Order

Support orders can be modified, but you have to show a material change in circumstances. The clearest way to meet that standard is a change in income or custody time that would move the calculated amount by at least 15%.³ Common triggers are a significant raise or pay cut, involuntary job loss, a child aging out, or a real shift in parenting time.

Administrative orders go back to the CSSD for modification. Court orders go through the Superior Court on a Motion to Modify. The filing fee is $75, waived when parents file jointly or by stipulation, and low-income parents can apply for a separate fee waiver.⁹

One rule catches people out: modifications are not retroactive. Under the federal Bradley Amendment, arrearages that have already accrued cannot be reduced. In Alaska, the new amount takes effect from the date the modification request is filed, not the date your circumstances actually changed.¹⁰ If your income dropped six months ago and you file today, you still owe the full original amount for those six months. Filing promptly matters more than most people realize.

When One Parent Lives Out of State

If one parent lives in Alaska and the other lives somewhere else, the Uniform Interstate Family Support Act (UIFSA), codified at AS 25.25.101, controls. Only one state’s order is in effect at a time. The state that issued the original order keeps exclusive jurisdiction to modify it as long as one of the parties or the child still lives there; every other state has to honor that order. If nobody involved still lives in the original state, another state can take over modification. Registering an out-of-state order in Alaska goes through the Superior Court, and there is no filing fee for a motion to modify a registered foreign child support order.⁹

Bankruptcy Doesn’t Wipe Out Support

Child support survives bankruptcy. Domestic support obligations are specifically excluded from discharge in both Chapter 7 and Chapter 13.¹¹ The automatic stay that normally halts collection also doesn’t apply to most support enforcement. The following continue even after a bankruptcy petition is filed:

Establishing or modifying a support order
Income withholding
Suspending a driver’s, professional, or recreational license for nonpayment
Intercepting federal or state tax refunds for past-due support
Enforcing medical support obligations
Reporting overdue support to credit agencies¹²

Taxes and Claiming the Child

Child support is tax-neutral at the federal level. The paying parent gets no deduction, and the receiving parent doesn’t report it as income.

Which parent claims the child as a dependent is a separate question. By default, the custodial parent (the one with whom the child spent more nights during the year) claims the child. The custodial parent can release that claim by signing IRS Form 8332, letting the noncustodial parent claim the child instead, and the noncustodial parent has to attach the signed form to their return every year they claim the child.¹³ If your divorce or custody agreement specifies who claims the child, make sure the Form 8332 paperwork matches before filing. For agreements finalized after 2008, the IRS won’t accept a court order alone without the signed release.
