The SSR and Low-Income Safeguards
The child support formula for $9,300 includes the SSR protection. For 2026, this is $2,394. It guarantees the parent paying $1,387 isn't left with less than $2,394 to cover their own basic rent and food.
Income Bracket Context
At $9,300/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 $1,387 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 $9,300 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 $1,387 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
For one child at $9,300/mo, the $1,387 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $2,094 — an increase of $707 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $9,300 — at $9,400/mo — would face a presumptive order of $1,396/mo for one child in Washington. Those earning slightly less at $9,200/mo would owe $1,379/mo. These neighboring brackets help illustrate how Washington's 2026 schedule scales support incrementally with income.
Calculation Summary & Requirements
In summary, the 2026 guidelines for $9,300 provide a clear expectation of $1,387 for one child. While Washington rules add complexity, the $9,300 baseline remains the most important factor.
