Child support in Washington depends on both parents’ incomes. When one parent chooses not to work, the court may still “impute” income—meaning it assigns an income amount based on what that parent could earn—under certain circumstances.
How Washington determines income for child support
Washington courts use the state’s child support schedule to calculate payment amounts. This schedule starts with each parent’s actual income from wages, self-employment, or other sources. If a parent has no income, the court reviews work history, education, training, and local job opportunities to decide whether to impute income.
When income may be imputed
If a parent remains voluntarily unemployed or underemployed, the court can assign an income amount even without a paycheck. For example, a parent with a steady work history who chooses to stay home without a valid reason related to the child’s needs may still have earning potential. In that case, the court might base the imputed income on full-time earnings at the parent’s previous job, a similar position, or full-time minimum wage.
Exceptions for caregiving and other circumstances
Courts do not impute income to stay-at-home parents every time. Judges may decide against assigning earning capacity when a parent cares for a child under the age of two, provides full-time care for a child with special needs, or faces a serious health issue. They consider the child’s best interests and evaluate whether the parent’s choice to remain at home supports the child’s well-being.
Why this matters
Imputed income directly affects the child support amount and can significantly change monthly payments. Parents who understand how Washington applies these rules can prepare accurate financial information and present evidence about their work status when necessary.
Child support rules on imputed income aim to keep support fair between parents while ensuring children receive consistent care. By understanding these standards, both parents can make informed choices about work, caregiving, and financial obligations.
