The SSR and Low-Income Safeguards
The 2026 Washington schedule incorporates the $2,394 SSR. For a $4,200 income, the $1,320 obligation is subject to a check to ensure the payor isn't reduced to a net income below the poverty threshold.
Income Bracket Context
At $4,200/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 $1,320 for 2 children is typically applied as-is at this level, with fewer deviations than lower or higher income tiers.
Deviation Likelihood in Washington
At the $4,200 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 $1,320 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
The $1,320 for 2 children at $4,200/mo reflects Washington's standard two-child rate. Compared to a one-child order ($867) at the same income, the second child adds $453/mo — a 52% increase rather than a full doubling, reflecting shared household costs.
Related Income Tiers
Parents earning slightly more than $4,200 — at $4,300/mo — would face a presumptive order of $1,336/mo for 2 children in Washington. Those earning slightly less at $4,100/mo would owe $1,306/mo. These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
Calculation Summary & Requirements
Determining support for a $4,200 income in Washington is a multi-step process. While the 2026 tables set a $1,320 baseline for 2 children, the final order in Washington considers deviations and the SSR.
