Washington Child Support Guidelines (2026 Updates)
Calculating support for one child when the combined net income is $2,800 involves more than a simple table lookup. Factors like the Self-Support Reserve and local King County rules often influence the final order.
Breakdown of the $2,800 Calculation
With a combined $2,800 per month, parents are expected to provide $609 in basic support for one child. The 2026 rules split this obligation based on each parent's proportional share of the $2,800.

The SSR and Low-Income Safeguards
A vital component of the 2026 system is the Self-Support Reserve (SSR), set at $2,394. If paying $609 would leave the payor with less than $2,394, the court may reduce the obligation for fairness.
