Washington Child Support Guidelines (2026 Updates)
The 2026 state guidelines provide clear estimates for one child and a $12,400 monthly income. By examining the $12,400 tier, we can establish the mathematical baseline used by Washington judges.
Breakdown of the $12,400 Calculation
The $1,616 amount for one child at the $12,400 level was established by the Washington State Legislature using updated economic data. This ensures $1,616 is sufficient to sustain the children's needs.
High-Income Notice
Because your combined income of $12,400 exceeds the $12,000 statutory ceiling, the $1,616 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 $12,400, 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 $1,616 limit.
Income Bracket Context
At $12,400/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 $1,616, particularly for lifestyle-based deviation arguments in Washington.
Deviation Likelihood in Washington
High-income deviation arguments are frequently raised in Washington at the $12,400 level. Since the schedule caps at $12,000 combined net income, the $1,616 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 $12,400/mo, the $1,616 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $2,450 — an increase of $834 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $12,400 — at $12,500/mo — would face a presumptive order of $1,626/mo for one child in Washington. Those earning slightly less at $12,300/mo would owe $1,605/mo. These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
