Presumptive Base Support
$1,446/ mo
In King County, courts apply the standard Washington economic schedule. For a combined net income of $5,000 with 2 children, the presumptive base support is $1,446 per month. This amount is typically shared between parents based on their proportional income share.
How Washington State Calculates Child Support in 2026
Washington State uses the Income Shares Model, where both parents' monthly net incomes are combined. A proportional share is dedicated to the children, reflecting what would have been spent if the household remained together.
The 2026 Schedule
The 2026 economic tables cover combined monthly net incomes from $0 to $50,000.
- Statutory minimum: $50 per child per month.
- Calculations cover all 39 Washington counties.
- Updated for 2026 economic standards.
The Self-Support Reserve (SSR)
Washington's primary low-income protection is the SSR, set at approximately $2,394 per month for 2026. If a payment would leave the payer with less than this, the court may deviate the payment downward.
The 45% Net Income Cap
Total support obligations typically cannot legally exceed 45% of a parent's monthly net income without explicit judicial approval for good cause.
Frequently Asked Questions About Washington Child Support
The statutory minimum child support in Washington is $50 per child per month. Judges may deviate below this amount in extraordinary circumstances only, to ensure the paying parent's self-support reserve is protected.
Washington uses an Income Shares Model. Both parents' net incomes are calculated and combined. The total presumptive support obligation is derived from the state's 2026 economic table and then split proportionally between the parents based on their percentage of the combined income.
The 2026 Self-Support Reserve (SSR) is approximately $2,394 per month. This low-income protection ensures that a paying parent is not left with less than approximately $2,394 to live on after making a basic child support payment.
No, the basic child support obligation covers only food, shelter, and basic clothing. Extraordinary expenses, such as work-related daycare, health insurance premiums, and approved educational costs, are apportioned separately based on the parents' proportional share of income.
