Washington Child Support Guidelines (2026 Updates)
The 2026 state guidelines provide clear estimates for one child and a $2,900 monthly income. By examining the $2,900 tier, we can establish the mathematical baseline used by Washington judges.
Breakdown of the $2,900 Calculation
The $630 amount for one child at the $2,900 level was established by the Washington State Legislature using updated economic data. This ensures $630 is sufficient to sustain the children's needs.

The SSR and Low-Income Safeguards
Regardless of your share of the $2,900, 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 $630 limit.
Income Bracket Context
At $2,900/mo, this household falls in the lower income bracket of Washington's 2026 schedule — below the state median of $7,114/mo. At this level, SSR protections and low-income deviations are more likely to influence the final order than the presumptive $630 figure.
Deviation Likelihood in Washington
At the $2,900 level, deviation requests are less common but still possible in Washington. The most frequent grounds are extraordinary healthcare costs, shared custody arrangements, or documented debts. The presumptive $630 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
For one child at $2,900/mo, the $630 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $966 — an increase of $336 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $2,900 — at $3,000/mo — would face a presumptive order of $652/mo for one child in Washington. Those earning slightly less at $2,800/mo would owe $609/mo. These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
Calculation Summary & Requirements
Successfully managing support at the $2,900 level starts with knowing the 2026 rules. For one child, the $630 calculation is the framework for all negotiations and orders in Washington.
Accuracy & Legal Status
The $630 amount and other calculations provided for a $2,900 income are estimates based on the 2026 Washington Child Support Schedule. Actual orders in Washington may vary based on case details, discretion, and local rules.
