The SSR and Low-Income Safeguards
The child support formula for $10,900 includes the SSR protection. For 2026, this is $2,394. It guarantees the parent paying $1,542 isn't left with less than $2,394 to cover their own basic rent and food.
Income Bracket Context
At $10,900/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 $1,542, particularly for lifestyle-based deviation arguments in Washington.
Deviation Likelihood in Washington
At the $10,900 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 $1,542 is upheld in the majority of standard cases at this income tier.
Children-Specific Insight
For one child at $10,900/mo, the $1,542 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $2,322 — an increase of $780 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $10,900 — at $11,000/mo — would face a presumptive order of $1,545/mo for one child in Washington. Those earning slightly less at $10,800/mo would owe $1,539/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 $10,900 provide a clear expectation of $1,542 for one child. While Washington rules add complexity, the $10,900 baseline remains the most important factor.

DSHS and the Washington Superior Court are the final authorities on support orders. These 2026 $10,900 and $1,542 estimates for one child help explain the general legal framework in Washington State.
