Washington Child Support Guidelines (2026 Updates)
Calculating support for one child when the combined net income is $13,500 involves more than a simple table lookup. Factors like the Self-Support Reserve and local Benton County rules often influence the final order.
Breakdown of the $13,500 Calculation
With a combined $13,500 per month, parents are expected to provide $1,729 in basic support for one child. The 2026 rules split this obligation based on each parent's proportional share of the $13,500.
High-Income Notice
Because your combined income of $13,500 exceeds the $12,000 statutory ceiling, the $1,729 base is a minimum starting point. Judges in Benton County, WA have discretion to increase support proportional to the family's standard of living.
Note: The 45% net income cap remains a vital legal defense.
The SSR and Low-Income Safeguards
A vital component of the 2026 system is the Self-Support Reserve (SSR), set at approximately $2,394. If paying $1,729 would leave the payor with less than approximately $2,394, the court may reduce the obligation for fairness.
Application in Benton County Superior Court
While the 2026 economic schedule is uniform statewide, the Benton/Franklin Superior Court handles procedural enforcement. In Benton County, judges may require additional proof of income before finalizing the $1,729 order.
Calculation Summary & Requirements
Finalizing a support order at the $13,500 level requires attention to the 2026 guidelines. Since $1,729 is the starting point for one child, you can better prepare for the financial change in Benton County, WA.
