Washington Child Support Guidelines (2026 Updates)
The 2026 state guidelines provide clear estimates for one child and a $15,500 monthly income. By examining the $15,500 tier, we can establish the mathematical baseline used by Washington judges.
Breakdown of the $15,500 Calculation
The $1,923 amount for one child at the $15,500 level was established by the Washington State Legislature using updated economic data. This ensures $1,923 is sufficient to sustain the children's needs.
High-Income Notice
Because your combined income of $15,500 exceeds the $12,000 statutory ceiling, the $1,923 base is a minimum starting point. Judges in Washington State have discretion to increase support proportional to the family's standard of living. Want a complete breakdown including deviations and expenses?

Note: The 45% net income cap remains a vital legal defense.
The SSR and Low-Income Safeguards
Regardless of your share of the $15,500, the SSR of $2,394 may apply if your net income is low. The court's priority is the child, but they must also ensure the payor can function within the $1,923 limit.
Income Bracket Context
At $15,500/mo, this household falls in the upper income bracket of Washington's 2026 schedule — above the state median of $7,114/mo. At this level, courts have wider discretion to order above the presumptive $1,923, particularly for lifestyle-based deviation arguments in Washington.
Deviation Likelihood in Washington
High-income deviation arguments are frequently raised in Washington at the $15,500 level. Since the schedule caps at $12,000 combined net income, the $1,923 figure is a floor — not a ceiling. Attorneys often argue for upward deviations based on the children's established standard of living and available parental resources.
Children-Specific Insight
For one child at $15,500/mo, the $1,923 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $2,966 — an increase of $1,043 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $15,500 — at $15,600/mo — would face a presumptive order of $1,933/mo for one child in Washington. Those earning slightly less at $15,400/mo would owe $1,914/mo. These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
