Washington Child Support Guidelines (2026 Updates)
Washington's 2026 child support laws are designed to be predictable. This review explains how the state arrives at the support figure for one child at the $1,000 mark, providing clarity for the process in King County.
Breakdown of the $1,000 Calculation
Washington's 2026 schedule provides a specific line item for $1,000 net income. For families with one child, this dictates a $477 base obligation, though King County judges may deviate for cause.
Low-Income Protective Measures
For families with a combined monthly income of $1,000, 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

Income Bracket Context
At $1,000/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 King County
Deviation requests are very common at the $1,000 income level in King 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.
