Washington Child Support Guidelines (2026 Updates)
Calculating support for one child when the combined net income is $10,400 involves more than a simple table lookup. Factors like the Self-Support Reserve and local Washington rules often influence the final order.
Breakdown of the $10,400 Calculation
With a combined $10,400 per month, parents are expected to provide $1,495 in basic support for one child. The 2026 rules split this obligation based on each parent's proportional share of the $10,400.

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 $1,495 would leave the payor with less than $2,394, the court may reduce the obligation for fairness.
Income Bracket Context
At $10,400/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 $1,495, particularly for lifestyle-based deviation arguments in Washington.
Deviation Likelihood in Washington
At the $10,400 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 $1,495 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
For one child at $10,400/mo, the $1,495 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $2,258 — an increase of $763 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $10,400 — at $10,500/mo — would face a presumptive order of $1,507/mo for one child in Washington. Those earning slightly less at $10,300/mo would owe $1,484/mo. These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
Calculation Summary & Requirements
Finalizing a support order at the $10,400 level requires attention to the 2026 guidelines. Since $1,495 is the starting point for one child, you can better prepare for the financial change in Washington State.
