Washington Child Support Guidelines (2026 Updates)
Calculating support for one child when the combined net income is $4,100 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 $4,100 Calculation
With a combined $4,100 per month, parents are expected to provide $857 in basic support for one child. The 2026 rules split this obligation based on each parent's proportional share of the $4,100.

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 $857 would leave the payor with less than $2,394, the court may reduce the obligation for fairness.
Income Bracket Context
At $4,100/mo, this household sits within Washington's standard mid-range bracket on the 2026 schedule, near the state median of $7,114/mo. The presumptive $857 for one child is typically applied as-is at this level, with fewer deviations than lower or higher income tiers.
Deviation Likelihood in Washington
At the $4,100 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 $857 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
For one child at $4,100/mo, the $857 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $1,306 — an increase of $449 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $4,100 — at $4,200/mo — would face a presumptive order of $867/mo for one child in Washington. Those earning slightly less at $4,000/mo would owe $843/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 $4,100 level requires attention to the 2026 guidelines. Since $857 is the starting point for one child, you can better prepare for the financial change in Washington State.
