Wyoming Child Support Calculator

Wyoming uses the income shares model under Statute § 20-2-304, combining both parents' net monthly incomes and applying a statutory table based on the number of children. For example, $5,000 combined net income yields a $693 presumptive obligation for one child. Each parent pays their proportional share — if one parent earns 60% of combined income, they pay 60% of the obligation.

Wyoming uses net income, calculated by subtracting federal, state, and local taxes, FICA contributions, mandatory retirement payments, union dues, and health insurance premiums from gross income. Gross income includes wages, salaries, commissions, bonuses, self-employment earnings, and investment income from all sources. If a parent fails to provide financial information, the court may impute income at minimum wage for 40 hours per week.

Wyoming Statute § 20-2-304 provides three calculation methods based on custody. Basic calculation applies to sole custody arrangements. Shared custody applies when each parent has overnights exceeding 25% of the year — the total obligation is multiplied by 150% and offset between parents. Split custody applies when each parent has physical custody of at least one child, with per-child obligations calculated and offset.

Wyoming allows child support modification when a material change in circumstances occurs. The state presumes a change is material if recalculating support under current guidelines produces an amount differing by 20% or more from the existing order. Common grounds include job loss, significant income changes, changes in custody arrangements, or changes in the child's needs. Either parent may petition the court for modification.

The presumptive child support amount under § 20-2-304 covers basic needs including housing, food, clothing, and transportation. Beyond the base amount, courts may order additional contributions for healthcare premiums, unreimbursed medical expenses, childcare costs necessary for employment or education, and extraordinary expenses such as special education needs. These additional costs are typically split proportionally based on each parent's share of combined net income.

Wyoming has no statutory maximum on child support orders, though federal law caps wage garnishment at 50% of net income. On the low end, the statutory table begins at $833 combined net monthly income — below that threshold, the non-custodial parent pays 25% of net income. Wyoming also enforces a self-support reserve at the federal poverty level ($1,255 per month in 2024), reducing obligations for low-income obligors.

Child support in Wyoming generally continues until the child turns 18 years old. If the child is still enrolled in high school at age 18, support continues until graduation or the child turns 19, whichever comes first. Support may also terminate if the child marries, is emancipated, or enters active military duty. Parents cannot waive child support obligations on behalf of their children.

Wyoming enforces child support through multiple mechanisms managed by the Department of Family Services. Enforcement tools include income withholding from wages, interception of federal and state tax refunds, suspension of driver's licenses and professional licenses, passport denial for arrears exceeding $2,500, liens on property, and contempt of court proceedings that can result in fines or jail time.
