These figures are the presumptive basic support obligation from the 2026 Washington State economic table. Actual court orders may differ based on custody arrangements, healthcare costs, and judicial decisions.
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.
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. Fill out your worksheet to see how this model applies to your specific income.
The 2026 economic tables cover combined monthly net incomes from $0 to $50,000.
Washington's primary low-income protection is the SSR, set at $2,394 per month for 2026. If a payment would leave the payer with less than this, the court may deviate the payment downward.
Total support obligations typically cannot legally exceed 45% of a parent's monthly net income without explicit judicial approval for good cause.
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.
