Washington Child Support Guidelines (2026 Updates)
Washington's 2026 child support laws are designed to be predictable. This review explains how the state arrives at the support figure for one child at the $28,500 mark, providing clarity for the process in King County.
Breakdown of the $28,500 Calculation
Washington's 2026 schedule provides a specific line item for $28,500 net income. For families with one child, this dictates a $2,876 base obligation, though King County judges may deviate for cause.
High-Income Notice
Because your combined income of $28,500 exceeds the $12,000 statutory ceiling, the $2,876 base is a minimum starting point. Judges in King 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
The 2026 Washington schedule incorporates the approximately $2,394 SSR. For a $28,500 income, the $2,876 obligation is subject to a check to ensure the payor isn't reduced to a net income below the poverty threshold.
Application in King County Superior Court
While the 2026 economic schedule is uniform statewide, the King County Superior Court handles procedural enforcement. In King County, judges may require additional proof of income before finalizing the $2,876 order.
Calculation Summary & Requirements
Determining support for a $28,500 income in Washington is a multi-step process. While the 2026 tables set a $2,876 baseline for one child, the final order in King County considers deviations and the SSR.
Accuracy & Legal Status
While we strive for accuracy, these figures for $28,500 are for informational purposes. The 2026 guidelines are subject to change, and the King County Superior Court has the final authority on all support amounts.
