Washington Child Support Guidelines (2026 Updates)
Understanding Washington child support for a combined monthly net income of $120,600 requires reviewing the 2026 economic schedules. Whether filing in Wahkiakum County or elsewhere, the base amount depends on the proportion of parental income dedicated to the children.
Breakdown of the $120,600 Calculation
Applying the Income Shares approach to a $120,600 income, Washington assumes parents would dedicate Court Discretion of their combined resources to one child. This serves as the presumptive transfer payment.
What This Number Means For You
At $7,000 or more in monthly net income, the standard 2026 economic table still applies as long as combined income stays under $50,000 — but the 45% net income cap becomes something worth paying attention to. Courts can't order you to pay more than 45% of your net monthly income in total child support without making a specific finding of good cause, and at higher income levels that ceiling matters. Deviation requests are also more common here, particularly around private school tuition, extracurricular costs, and travel expenses for custody exchanges. Use the scenario comparison tool to model how different custody arrangements and expense splits change your total obligation before you sit down with the other parent.
Number of Children: What To Expect
A single-child obligation is the lowest tier in Washington's table, and it's also the most frequently modified when custody schedules change. If your parenting time increases significantly, a modification petition is worth running through the calculator first.
What To Do After Seeing Your Number
The number on this page is a presumptive estimate — it's where the court starts, not necessarily where it ends. Don't let it panic you before you understand what's actually negotiable. Your parenting time schedule directly affects what you pay, and even a modest increase in overnight stays can produce a meaningful credit under Washington's residential time formula. Extraordinary expenses like daycare and health insurance premiums get added on top of the base, so your real total may be higher than what you see here. You also have the legal right to request a deviation if your circumstances qualify — high debt, other dependents, or a shared custody arrangement all count.
