Washington Child Support Guidelines (2026 Updates)
The transition to a dual-household structure relies on the accurate calculation of support based on your combined net income of $13,400. In Washington State, this follows the Income Shares Model to benefit one child.
Breakdown of the $13,400 Calculation
For a combined income of $13,400, the 2026 guidelines set the presumptive support for one child at $1,719. This ensures the transfer payment fairly reflects the total resources available to the family.
High-Income Notice
Because your combined income of $13,400 exceeds the $12,000 statutory ceiling, the $1,719 base is a minimum starting point. Judges in Washington State have discretion to increase support proportional to the family's standard of living. Want a complete breakdown including deviations and expenses?

The SSR and Low-Income Safeguards
The child support formula for $13,400 includes the SSR protection. For 2026, this is $2,394. It guarantees the parent paying $1,719 isn't left with less than $2,394 to cover their own basic rent and food.
Income Bracket Context
At $13,400/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 $1,719, particularly for lifestyle-based deviation arguments in Washington.
Deviation Likelihood in Washington
High-income deviation arguments are frequently raised in Washington at the $13,400 level. Since the schedule caps at $12,000 combined net income, the $1,719 figure is a floor — not a ceiling. Attorneys often argue for upward deviations based on the children's established standard of living and available parental resources.
Children-Specific Insight
For one child at $13,400/mo, the $1,719 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $2,620 — an increase of $901 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $13,400 — at $13,500/mo — would face a presumptive order of $1,729/mo for one child in Washington. Those earning slightly less at $13,300/mo would owe $1,709/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 $13,400 provide a clear expectation of $1,719 for one child. While Washington rules add complexity, the $13,400 baseline remains the most important factor.
Accuracy & Legal Status
DSHS and the Washington Superior Court are the final authorities on support orders. These 2026 $13,400 and $1,719 estimates for one child help explain the general legal framework in Washington State.
