Washington Child Support Guidelines (2026 Updates)
Calculating support for one child when the combined net income is $3,400 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 $3,400 Calculation
With a combined $3,400 per month, parents are expected to provide $740 in basic support for one child. The 2026 rules split this obligation based on each parent's proportional share of the $3,400.

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 $740 would leave the payor with less than $2,394, the court may reduce the obligation for fairness.
Income Bracket Context
At $3,400/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 $740 figure.
Deviation Likelihood in Washington
At the $3,400 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 $740 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
For one child at $3,400/mo, the $740 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $1,132 — an increase of $392 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $3,400 — at $3,500/mo — would face a presumptive order of $762/mo for one child in Washington. Those earning slightly less at $3,300/mo would owe $718/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 $3,400 level requires attention to the 2026 guidelines. Since $740 is the starting point for one child, you can better prepare for the financial change in Washington State.
