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 $28,200. In Washington State, this follows the Income Shares Model to benefit one child.
Breakdown of the $28,200 Calculation
For a combined income of $28,200, the 2026 guidelines set the presumptive support for one child at $2,858. This ensures the transfer payment fairly reflects the total resources available to the family.
High-Income Notice
Because your combined income of $28,200 exceeds the $12,000 statutory ceiling, the $2,858 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 $28,200 includes the SSR protection. For 2026, this is $2,394. It guarantees the parent paying $2,858 isn't left with less than $2,394 to cover their own basic rent and food.
Income Bracket Context
At $28,200/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 $2,858, particularly for lifestyle-based deviation arguments in Washington.
Deviation Likelihood in Washington
High-income deviation arguments are frequently raised in Washington at the $28,200 level. Since the schedule caps at $12,000 combined net income, the $2,858 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 $28,200/mo, the $2,858 obligation reflects Washington's base rate. Parents adding a second child to the order would see this figure rise to $4,680 — an increase of $1,822 — reflecting the additional resources required under the 2026 schedule.
Related Income Tiers
Parents earning slightly more than $28,200 — at $28,300/mo — would face a presumptive order of $2,864/mo for one child in Washington. Those earning slightly less at $28,100/mo would owe $2,852/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 $28,200 provide a clear expectation of $2,858 for one child. While Washington rules add complexity, the $28,200 baseline remains the most important factor.
Accuracy & Legal Status
DSHS and the Washington Superior Court are the final authorities on support orders. These 2026 $28,200 and $2,858 estimates for one child help explain the general legal framework in Washington State.
