Child Support Calculation Worksheet - Alaska

IMPORTANT: THIS IS A PREPARATION GUIDE — NOT THE OFFICIAL COURT WORKSHEET

Alaska Civil Rule 90.3(e) requires each parent in a court proceeding involving child support to file a sworn income statement with supporting documentation. The court provides the DR-305 Child Support Guidelines Affidavit. Use the applicable official calculation form—DR-306 (shared custody), DR-307 (divided custody), or DR-308 (hybrid custody)—when that custody arrangement applies.
This template provides preparation fields only. Transfer the information to the current official affidavit and calculation forms before filing.
The official form is available at https://courts.alaska.gov/shc/family/support.htm.
Do not file this document directly with the court.

1. Case Information

2. Children Subject to This Order

Total Number of Children: [____]

Custody Arrangement:
☐ Primary Physical Custody
☐ Shared Physical Custody (each parent has physical custody for at least 30% of overnights)
☐ Divided Custody (each parent has primary custody of at least one child)
☐ Hybrid Custody

3. Income Determination

Noncustodial Parent — Annual Gross Income

Custodial Parent — Annual Gross Income (for shared custody calculation)

4. Allowable Deductions

Noncustodial Parent Deductions

5. Adjusted Annual Income

Low-income adjustment (Rule 90.3(a)(5)): If this parent's total annual income from all sources is $30,000 or less, calculate both amounts below and use the lesser as adjusted annual income:

☐ Adjusted annual income exceeds $138,000
☐ Evidence presented for inclusion of income above $138,000: ☐ Yes ☐ No

6. Child Support Calculation

Primary Custody Percentage Schedule

Calculation

Rule 90.3(c)(3) generally sets a $50 monthly minimum, subject to the exceptions in Rule 90.3(a)(3) and (b). Apply the income limit and minimum when calculating each parent's Rule 90.3(a) amount for shared, divided, or hybrid custody.

7. Shared, Divided, and Hybrid Custody Adjustments

Shared Custody (Rule 90.3(b))

☐ Shared custody applies

Parent obligated to pay: ☐ Parent A ☐ Parent B

If the custody percentages do not accurately reflect the ratio of funds each parent will directly spend on the children, Rule 90.3(b)(1)(B) permits the court to vary the percentages to reflect its findings. The order may use a different monthly payment schedule in the limited circumstances stated in Rule 90.3(b)(1)(D).

Divided Custody (Rule 90.3(b))

☐ Divided custody applies

Parent obligated to pay: ☐ Parent A ☐ Parent B

Divided custody is an unusual circumstance under Rule 90.3(b)(2). After offsetting the two primary-custody calculations, the court must consider whether the result should be varied under Rule 90.3(c)(1).

Hybrid Custody (Rule 90.3(b)(3))

☐ Hybrid custody applies: use current court form DR-308. Calculate the primary-custody and shared-custody components with the Rule 90.3(a)(2) percentages adjusted pro rata for the children in each custody type, combine the amounts, and consider a variation under Rule 90.3(c)(1).

8. Health Insurance and Additional Expenses

9. Deviation Factors

☐ No deviation requested

☐ Deviation requested based on:

☐ Especially large family size
☐ Significant income of a child
☐ Health or other extraordinary needs of the child
☐ Unusually low expenses
☐ Other: [________________________________]

Rule 90.3(c)(1) requires clear and convincing evidence that the ordinary calculation would cause manifest injustice; the court must give written reasons for a variation. An additional award based on adjusted annual income above $138,000 is governed separately by Rule 90.3(c)(2).

Proposed deviation amount: $ [________________________________]

Justification:
[________________________________]
[________________________________]

10. Duration and Modification

Duration stated in the current or proposed order: [________________________________]

Child and event to review for a possible duration change: [________________________________]

Modification:

☐ This is a modification of a prior order dated [__/__/____]
☐ Existing order amount: $ [____________] per month
☐ Recalculated amount: $ [____________] per month
☐ Recalculated Rule 90.3 support (including qualifying health insurance payments) is more than 15% greater or less than the outstanding order: ☐ Yes ☐ No

11. State-Specific Notes

1. Percentage of Income Model: Alaska uses a Percentage of Income model focused primarily on the noncustodial parent's income, unlike Income Shares states that combine both parents' incomes.

2. Income Cap: The standard calculation applies to the first $138,000 of adjusted annual income. Income above this threshold requires separate evidence and court determination.

3. Permanent Fund Dividend: The Alaska Permanent Fund Dividend is included in gross income for child support calculation purposes.

4. Shared Custody Threshold: Shared custody provisions apply when each parent has physical custody for at least 30% of overnights annually (approximately 110 nights).

5. Military Benefits: Include pay, allowances, and significant in-kind housing benefits that reduce living expenses where applicable. Do not exclude military housing benefits categorically.

6. Currency Check: Use the Alaska Court System's current Rule 90.3 compilation and current DR-305 through DR-308 forms. Do not rely on a bill number or an older form revision as proof of the current calculation rules.
