Washington Child Support Guidelines (2026 Updates)
The 2026 state guidelines provide clear estimates for one child and a $900 monthly income. By examining the $900 tier, we can establish the mathematical baseline used by Lewis County judges.
Breakdown of the $900 Calculation
The $477 amount for one child at the $900 level was established by the Washington State Legislature using updated economic data. This ensures $477 is sufficient to sustain the children's needs.
Low-Income Protective Measures
For families with a combined monthly income of $900, Washington's 2026 guidelines trigger automatic poverty protections. At this level, the standard $477 obligation is often reduced to the statutory minimum of $50 per child per month. Want a complete breakdown including deviations and expenses?

The SSR and Low-Income Safeguards
Regardless of your share of the $900, the SSR of $2,394 may apply if your net income is low. The court's priority is the child, but they must also ensure the payor can function within the $477 limit.

Income Bracket Context
At $900/mo, this household falls in the lower income bracket of Washington's 2026 schedule — below the state median of $7,114/mo. At this level, SSR protections and low-income deviations are more likely to influence the final order than the presumptive $477 figure.
Deviation Likelihood in Lewis County
Deviation requests are very common at the $900 income level in Lewis County. Because $477 at this tier frequently conflicts with the $2,394 SSR floor, judges routinely reduce orders to the $50/child statutory minimum. Parents at this income level should come prepared with full financial documentation.
