The transition to a dual-household structure relies on the accurate calculation of support based on your combined net income of $17,500. In King County, WA, this follows the Income Shares Model to benefit 2 children.
Breakdown of the $17,500 Calculation
For a combined income of $17,500, the 2026 guidelines set the presumptive support for 2 children at $3,278. This ensures the transfer payment fairly reflects the total resources available to the family.
High-Income Notice
